Duopa

Generic Name: carbidopa and levodopa
Dosage Form: enteral suspension

Indications and Usage for Duopa

Duopa is indicated for the treatment of motor fluctuations in patients with advanced Parkinson’s disease.

Duopa Dosage and Administration

Duopa Daily Dose

Duopa is administered over a 16-hour infusion period. The daily dose is determined by individualized patient titration and composed of:

  • A Morning Dose
  • A Continuous Dose
  • Extra Doses

The maximum recommended daily dose of Duopa is 2000 mg of the levodopa component (i.e., one cassette per day) administered over 16 hours. At the end of the daily 16-hour infusion, patients will disconnect the pump from the PEG-J and take their night-time dose of oral immediate-release carbidopa-levodopa tablets.

Treatment with Duopa is initiated in 3 steps [see Dosage and Administration (2.2)]:

  1. Conversion of patients to oral immediate-release carbidopa-levodopa tablets in preparation for Duopa treatment.
  2. Calculation and administration of the Duopa starting dose (Morning Dose and Continuous Dose) for Day 1.
  3. Titration of the dose as needed based on individual clinical response and tolerability.

Extra Doses

Duopa has an extra dose function that can be used to manage acute “Off” symptoms that are not controlled by the Morning Dose and the Continuous Dose administered over 16 hours. The extra dose function should be set at 1 mL (20 mg of levodopa) when starting Duopa. If the amount of the extra dose needs to be adjusted, it is typically done in 0.2 mL increments. The extra dose frequency should be limited to one extra dose every 2 hours. Administration of frequent extra doses may cause or worsen dyskinesias.

Once no further adjustments are required to the Duopa Morning Dose, Continuous Dose, or Extra Dose, this dosing regimen should be administered daily. Over time, additional changes may be necessary based on the patient’s clinical response and tolerability.

Initiation and Titration Instructions

Prepare for Duopa Treatment

Prior to initiating Duopa, convert patients from all other forms of levodopa to oral immediate-release carbidopa-levodopa tablets (1:4 ratio). Patients should remain on a stable dose of their concomitant medications taken for the treatment of Parkinson's disease before initiation of Duopa infusion.

Healthcare providers should ensure patients take their oral Parkinson's disease medications the morning of the PEG-J procedure.

Determine the Duopa Starting Dose for Day 1

The steps for determining the initial Duopa daily dosing (Morning Dose and Continuous Dose) for Day 1 are outlined below.

Step 1: Calculate and administer the Duopa Morning Dose for Day 1
a. Determine the total amount of levodopa (in milligrams) in the first dose of oral immediate-release carbidopa-levodopa that was taken by the patient on the previous day.
b. Convert the oral levodopa dose from milligrams to milliliters by multiplying the oral dose by 0.8 and dividing by 20 mg/mL. This calculation will provide the Morning Dose of Duopa in milliliters.
c. Add 3 milliliters to the Morning Dose to fill (prime) the intestinal tube to obtain the Total Morning Dose.
d. The Total Morning Dose is usually administered over 10 to 30 minutes.
e. Program the pump to deliver the Total Morning Dose.
Step 2: Calculate and administer the Duopa Continuous Dose for Day 1
a. Determine the amount of oral immediate-release levodopa that the patient received from oral immediate-release carbidopa-levodopa doses throughout the previous day (16 waking hours), in milligrams. Do not include the doses of oral immediate-release carbidopa-levodopa taken at night when calculating the levodopa amount.
b. Subtract the first oral levodopa dose in milligrams taken by the patient on the previous day (determined in Step 1 (a)) from the total oral levodopa dose in milligrams taken over 16 waking hours (determined in Step 2 (a)). Divide the result by 20 mg/mL. This is the dose of Duopa administered as a Continuous Dose (in mL) over 16 hours.
c. The hourly infusion rate (mL per hour) is obtained by dividing the Continuous Dose by 16 (hours). This value will be programmed into the pump as the continuous rate.
d. If persistent or numerous “Off” periods occur during the 16-hour infusion, consider increasing the Continuous Dose or using the Extra Dose function. If dyskinesia or Duopa-related adverse reactions occur, consider decreasing the Continuous Dose or stopping the infusion until the adverse reactions subside.

Duopa Titration

The daily dose of Duopa can be titrated as needed, based on the patient’s individual clinical response and tolerability after Day 1 of Duopa treatment and until a stable daily dose is maintained. Adjustments to concomitant Parkinson’s disease medications may be needed. In the controlled trial, the average number of titration days required to establish a stable Morning and Continuous Dose was 5 days. Additional dose adjustments may be necessary over time based on the patient level of activity and disease progression.

The recommendations for adjusting the Duopa Morning and Continuous Doses are provided below.

Morning Dose Adjustment

If there was an inadequate clinical response within 1 hour of the Morning Dose on the preceding day, adjust the Morning Dose (excluding the 3 mL to fill the tube) as follows:

  • If the Morning Dose on the preceding day was less than or equal to 6 mL, increase the Morning Dose by 1 mL.
  • If the Morning Dose on the preceding day was greater than 6 mL, increase the Morning Dose by 2 mL.

If the patient experienced dyskinesias or Duopa-related adverse reactions within 1 hour of the Morning Dose on the preceding day, decrease the Morning Dose by 1 mL.

Continuous Dose Adjustment

Consider increasing the Continuous Dose based on the number and volume of Extra Doses of Duopa (i.e., total amount of levodopa component) that were needed for the previous day and the patient’s clinical response.

Consider decreasing the Continuous Dose if the patient experienced troublesome dyskinesia, or other troublesome Duopa-related adverse reactions on the preceding day:

  • For troublesome adverse reactions lasting for a period of one hour or more, decrease the Continuous Dose by 0.3 mL per hour.
  • For troublesome adverse reactions lasting for two or more periods of one hour or more, decrease the Continuous Dose by 0.6 mL per hour.

Administration Information

  • Duopa should be used at room temperature. Take one Duopa cassette out of the refrigerator and out of the carton 20 minutes prior to use; failure to use the product at room temperature may result in the patient not receiving the right amount of medication.
  • Duopa is delivered as a 16-hour infusion through either a naso-jejunal tube for short-term administration or through a PEG-J for long-term administration.
  • The cassettes are for single-use only and should not be used for longer than 16 hours, even if some drug product remains.
  • An opened cassette should not be re-used.
  • The PEG-J should be disconnected from the pump at the end of the daily 16-hour administration period and flushed with room temperature potable water with a syringe.

Long-term administration of Duopa requires placement of a PEG-J outer transabdominal tube and inner jejunal tube by percutaneous endoscopic gastrostomy. Duopa is dispensed from medication cassette reservoirs that are specifically designed to be connected to the CADD®-Legacy 1400 pump.

Establishment of the transabdominal port should be performed by a gastroenterologist or other healthcare provider experienced in this procedure. See Table 1 for the recommended tubing sets for PEG-J administration.

For short-term, temporary administration of Duopa prior to PEG-J tube placement, treatment may be initiated by a naso-jejunal tube with observation of the patient’s clinical response. See Table 2 for the recommended tubing sets for naso-jejunal administration.

Discontinuation of Duopa

Avoid sudden discontinuation or rapid dose reduction in patients taking Duopa.

If patients need to discontinue Duopa, the dose should be tapered or patients should be switched to oral immediate-release carbidopa-levodopa tablets [see Warnings and Precautions (5.7)].

When using a PEG-J tube, Duopa can be discontinued by withdrawing the tube and letting the stoma heal. The removal of the tube should only be performed by a qualified healthcare provider.

Dosage Forms and Strengths

Enteral suspension: 4.63 mg carbidopa and 20 mg levodopa per mL in a single-use cassette. Each cassette contains approximately 100 mL of suspension.

Contraindications

Duopa is contraindicated in patients who are currently taking a nonselective monoamine oxidase (MAO) inhibitor (e.g., phenelzine and tranylcypromine) or have recently (within 2 weeks) taken a nonselective MAO inhibitor. Hypertension can occur if these drugs are used concurrently [see Drug Interactions (7.1 and 7.2)].

Warnings and Precautions

Gastrointestinal and Gastrointestinal Procedure-Related Risks

Because Duopa is administered using a PEG-J or naso-jejunal tube, gastrointestinal complications can occur.

These complications include bezoar, ileus, implant site erosion/ulcer, intestinal hemorrhage, intestinal ischemia, intestinal obstruction, intestinal perforation, pancreatitis, peritonitis, pneumoperitoneum, and post-operative wound infection. These complications may result in serious outcomes, such as the need for surgery or death.

Instruct patients to notify their healthcare provider immediately if they experience abdominal pain, prolonged constipation, nausea, vomiting, fever, or melanotic stool [see Patient Counseling Information (17)].

Falling Asleep During Activities of Daily Living and Somnolence

Patients treated with levodopa, a component of Duopa, have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes resulted in accidents. Although many of these patients reported somnolence while on levodopa, some perceived that they had no warning signs (sleep attack), such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some of these events have been reported more than one year after initiation of treatment.

Falling asleep while engaged in activities of daily living usually occurs in patients experiencing preexisting somnolence, although patients may not give such a history. For this reason, prescribers should reassess patients for drowsiness or sleepiness in Duopa-treated patients, especially since some of the events occur well after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities while taking Duopa.

Before initiating treatment with Duopa, advise patients about the potential to develop drowsiness and specifically ask about factors that may increase the risk for somnolence with Duopa such as the use of concomitant sedating medications or the presence of sleep disorders. Consider discontinuing Duopa in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating). If Duopa is continued, they should be advised to avoid driving and other potentially dangerous activities that might result in harm if the patient becomes somnolent.

Orthostatic Hypotension

Duopa-treated patients were more likely to experience a decline in orthostatic blood pressure than patients treated with oral immediate-release carbidopa-levodopa in the controlled clinical study. Orthostatic systolic hypotension (≥30 mm Hg decrease) occurred in 73% of Duopa-treated patients compared to 68% of patients treated with oral immediate-release carbidopa-levodopa in the controlled clinical study. Orthostatic diastolic hypotension (≥20 mm Hg decrease) occurred in 70% of Duopa-treated patients compared to 62% of patients treated with oral immediate-release carbidopa-levodopa. Inform patients about the risk for hypotension and syncope. Monitor patients for orthostatic hypotension, especially after starting Duopa or increasing the dose.

Hallucinations/Psychosis/Confusion

There is an increased risk for hallucinations and psychosis in patients taking Duopa. In the controlled clinical trial, hallucinations occurred in 5% of Duopa-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa. Confusion occurred in 8% of Duopa-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa, and psychotic disorder occurred in 5% of Duopa-treated patients compared to 3% of patients treated with oral immediate-release carbidopa-levodopa.

Hallucinations associated with levodopa may present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Confusion, insomnia, and excessive dreaming may accompany hallucinations. Abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychosis, disorientation, aggressive behavior, agitation, and delirium.

Because of the risk of exacerbating psychosis, patients with a major psychotic disorder should not be treated with Duopa. In addition, medications that antagonize the effects of dopamine used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of Duopa [see Drug Interactions (7.3)].

Impulse Control/Compulsive Behaviors

Patients may experience intense urges to gamble, increased sexual urges, intense urges to spend money, binge or compulsive eating, and/or other intense urges, and the inability to control these urges while taking one or more of the medications, including Duopa, that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease. In some cases, although not all, these urges were reported to have stopped when the dose was reduced or the medication was discontinued.

Because patients may not recognize these behaviors as abnormal, it is important for prescribers to ask patients or their caregivers specifically about the development of new or increased gambling urges, sexual urges, uncontrolled spending, binge or compulsive eating, or other urges while being treated with Duopa. Consider reducing the dose or discontinuing Duopa if a patient develops such urges.

Depression and Suicidality

In the controlled clinical trial, 11% of Duopa-treated patients developed depression compared to 3% of oral immediate-release carbidopa-levodopa-treated patients.

Monitor patients for the development of depression and concomitant suicidal tendencies.

Withdrawal-Emergent Hyperpyrexia and Confusion

A symptom complex that resembles neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction, withdrawal of, or changes in dopaminergic therapy. Avoid sudden discontinuation or rapid dose reduction in patients taking Duopa. If Duopa is discontinued, the dose should be tapered to reduce the risk of hyperpyrexia and confusion [see Dosage and Administration (2.4)].

Dyskinesia

Duopa may cause or exacerbate dyskinesias. In the controlled clinical trial, dyskinesia occurred in 14% of Duopa-treated patients compared to 12% of patients treated with oral immediate-release carbidopa-levodopa. The occurrence of dyskinesias may require a dosage reduction of Duopa or other medications used to treat Parkinson’s disease.

Neuropathy

In clinical studies, 19 of 412 (5%) patients treated with Duopa developed a generalized polyneuropathy. The onset of neuropathy could be determined in 13 of 19 patients. Most cases (12/19) were classified as subacute or chronic in onset. The neuropathy was most often characterized as sensory or sensorimotor. Electrodiagnostic testing performed in 16 patients was most often (15/16) consistent with an axonal polyneuropathy, and one patient was classified as having a demyelinating neuropathy. There was insufficient information to determine the potential role of vitamin deficiencies in the etiology of neuropathy associated with Duopa.

Patients should have clinical assessments for the signs and symptoms of peripheral neuropathy before starting Duopa. Monitor patients periodically for signs of neuropathy after starting Duopa, especially in patients with pre-existing neuropathy and in patients taking medications or those who have medical conditions that are also associated with neuropathy.

Cardiovascular Ischemic Events

In clinical studies, myocardial infarction and arrhythmia were reported in patients taking carbidopa-levodopa. Ask patients about symptoms of ischemic heart disease and arrhythmia, especially those with a history of myocardial infarction or cardiac arrhythmias.

Melanoma

Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2 to approximately 6-fold higher) of developing melanoma than the general population. Whether the increased risk observed was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. In the clinical studies, 2 of 416 (0.5%) Duopa-treated patients developed melanoma.

Appropriately qualified health care providers (e.g., dermatologists) should perform periodic skin examinations to monitor for melanoma in patients receiving Duopa.

Laboratory Test Abnormalities

Duopa may increase the risk for elevated (above the upper limit of normal for the reference range) blood urea nitrogen (BUN) and creatine phosphokinase (CPK). In the controlled clinical trial, the shift from a low or normal value at baseline to an increased BUN value was greater for Duopa-treated patients (13%) than for patients treated with oral immediate-release carbidopa-levodopa (4%). The shift from a low or normal value at baseline to an increased CPK value was greater for Duopa-treated patients (17%) than for patients treated with oral immediate-release carbidopa-levodopa (7%). The incidence of patients with a markedly increased BUN (≥10 mmol/L; ≥28 mg/dL) was greater for patients treated with Duopa (11%) than that for patients treated with oral immediate-release carbidopa-levodopa (0%). The incidence of patients with an increased CPK (>3 times the upper limit of normal) was greater for patients treated with Duopa (9%) than that for patients treated with oral immediate-release carbidopa-levodopa (0%).

Patients taking levodopa or carbidopa-levodopa may have increased levels of catecholamines and their metabolites in plasma and urine giving false positive results suggesting the diagnosis of pheochromocytoma in patients on levodopa and carbidopa-levodopa.

Glaucoma

Carbidopa-levodopa may cause increased intraocular pressure in patients with glaucoma. Monitor intraocular pressure in patients with glaucoma after starting Duopa.

Clinical Trials Experience

Because clinical studies are run under widely varying conditions, the incidence of adverse reactions observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical studies, 416 patients with advanced Parkinson’s disease received Duopa. 338 patients were treated with Duopa for more than 1 year, 233 patients were treated with Duopa for more than 2 years, and 162 patients were treated with Duopa for more than 3 years.

In a 12-week, active-controlled clinical trial (Study 1), a total of 71 patients with advanced Parkinson’s disease were enrolled and had a PEG-J procedure. Of these, 37 patients received Duopa and 34 received oral immediate-release carbidopa-levodopa.

The most common adverse reactions for Duopa (incidence at least 7% greater than oral immediate-release carbidopa-levodopa) were: complication of device insertion, nausea, depression, peripheral edema, hypertension, upper respiratory tract infection, oropharyngeal pain, atelectasis, and incision site erythema.

Table 3 lists the incidence of adverse reactions occurring in the Duopa-treated group (requiring at least 2 patients in this group) in Study 1 when the incidence was numerically greater than that for oral immediate-release carbidopa-levodopa.

Procedure and Device- Related Adverse Reactions

The most common adverse reactions associated with complications due to naso-jejunal (NJ) insertion were: oropharyngeal pain, abdominal distention, abdominal pain, abdominal discomfort, pain, throat irritation, gastrointestinal injury, esophageal hemorrhage, anxiety, dysphagia, and vomiting.

The most common adverse reactions associated with complications due to PEG-J insertion were: abdominal pain, abdominal discomfort, abdominal distension, flatulence, or pneumoperitoneum.

Additional adverse reactions that were co-reported with complication of naso-jejunal and PEG-J insertion included upper abdominal pain, duodenal ulcer, duodenal ulcer hemorrhage, erosive duodenitis, erosive gastritis, gastrointestinal hemorrhage, peritonitis, post-operative abscess, and small intestine ulcer.

Drug Interactions

Monoamine Oxidase (MAO) Inhibitors

The use of nonselective MAO inhibitors with Duopa is contraindicated [see Contraindications (4)]. Discontinue use of any nonselective MAO inhibitors at least two weeks prior to initiating Duopa.

The use of selective MAO-B inhibitors (e.g., rasagiline and selegiline) with Duopa may be associated with orthostatic hypotension. Monitor patients who are taking these drugs.

Antihypertensive Drugs

The concurrent use of Duopa with antihypertensive medications can cause symptomatic postural hypotension. A dose reduction of the antihypertensive medication may be needed after starting or increasing the dose of Duopa.

Dopamine D2 Receptor Antagonists and Isoniazid

Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone, metoclopramide, papaverine) and isoniazid may reduce the effectiveness of levodopa. Monitor patients for worsening Parkinson’s symptoms.

Iron Salts

Iron salts or multi-vitamins containing iron salts can form chelates with levodopa, carbidopa, and can cause a reduction in the bioavailability of Duopa. If iron salts or multi-vitamins containing iron salts are co-administered with Duopa, monitor patients for worsening Parkinson’s symptoms.

High-Protein Diet

Because levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be decreased in patients on a high-protein diet. Advise patients that a high-protein diet may reduce the effectiveness of Duopa.

USE IN SPECIFIC POPULATIONS

Pregnancy

Pregnancy Category C.

There are no adequate or well-controlled studies in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. In animal studies, carbidopa-levodopa has been shown to be developmentally toxic (including teratogenic effects) at clinically relevant doses. Duopa should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

When administered to pregnant rabbits throughout organogenesis, carbidopa-levodopa caused both visceral and skeletal malformations in fetuses at all doses and ratios of carbidopa-levodopa tested. No teratogenic effects were observed when carbidopa-levodopa was administered to pregnant mice throughout organogenesis.

There was a decrease in the number of live pups delivered by rats receiving carbidopa-levodopa during organogenesis.

Nursing Mothers

Carbidopa is excreted in rat milk. In a study of one nursing mother with Parkinson’s disease, excretion of levodopa in human milk was reported. Caution should be exercised when Duopa is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

In the controlled clinical trial, 49% of patients were 65 years and older, and 8% were 75 years and older. In patients 65 years and older, there was an increased risk for elevation of BUN and CPK (above the upper limit of the normal reference range for these laboratory analytes) during treatment with Duopa compared to the risk for patients less than 65 years.

Overdosage

Management of acute overdosage with Duopa is the same as management of acute overdosage with levodopa. Pyridoxine is not effective in reversing the actions of oral immediate-release carbidopa-levodopa.

In the event of an overdosage with Duopa, the infusion should be stopped and the pump disconnected immediately. Administer intravenous fluids and maintain an adequate airway. Patients should receive electrocardiographic monitoring for arrhythmias and hypotension.

Duopa Description

Duopa is a combination of carbidopa, an inhibitor of aromatic amino acid decarboxylation, and levodopa, an aromatic amino acid.

Carbidopa is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.2. It is designated chemically as (2S)-3-(3,4-dihydroxyphenyl)-2-hydrazino-2-methylpropanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is:

The content of carbidopa in Duopa is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. The 4.63 mg/mL of anhydrous carbidopa is equivalent to 5.0 mg/mL of carbidopa.

Levodopa is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (2S)-2-Amino-3-(3,4-dihydroxyphenyl) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is:

The inactive ingredients in Duopa are carmellose sodium and purified water.

Duopa - Clinical Pharmacology

Mechanism of Action

Carbidopa

When levodopa is administered orally, it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. Carbidopa inhibits the decarboxylation of peripheral levodopa, making more levodopa available for delivery to the brain.

Levodopa

Levodopa is the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa treats the symptoms of Parkinson's disease.

Pharmacodynamics

Because its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available to the brain. The addition of carbidopa to levodopa reduces the peripheral effects (e.g., nausea and vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa.

Pharmacokinetics

The pharmacokinetics of carbidopa and levodopa with 16-hour intrajejunal infusion of Duopa was evaluated in 18 patients with advanced Parkinson's disease who had been on Duopa therapy for 30 days or longer. Patients remained on their individualized Duopa doses.

The plasma concentrations versus time profile for levodopa with Duopa 16-hour intrajejunal infusion is presented in Figure 1.

Figure 1. Plasma Concentrations (mean ± standard deviation) versus Time Profile of Levodopa with Duopa (levodopa, 1580 ± 403 mg; carbidopa, 366 ± 92 mg) 16-Hour Infusion

Absorption and Bioavailability

Following initiation of the 16-hour intrajejunal infusion of Duopa, peak plasma levels of levodopa is reached at 2.5 hours. The absorption of levodopa may be decreased in patients on a high-protein diet because levodopa competes with certain amino acids for transport across the gut wall. The gastric emptying rate does not influence the absorption of Duopa since it is administered by continuous intestinal infusion. In a cross-study population pharmacokinetic analysis, Duopa had comparable bioavailability to the oral immediate-release carbidopa-levodopa (25/100 mg) tablets (over-encapsulated tablets). The estimated bioavailability for levodopa from Duopa relative to oral immediate-release carbidopa-levodopa tablets was 97% (95% confidence interval; 95% to 98%).

In the controlled clinical trial, the intra-subject variability in carbidopa and levodopa plasma concentrations were lower for patients treated with Duopa (N=33, 25% and 21%, respectively) than in patients treated with oral immediate-release carbidopa-levodopa (25/100 mg) tablets (N=28, 39% and 67%, respectively).

Distribution

Carbidopa is approximately 36% bound to plasma proteins. Levodopa is approximately 10-30% bound to plasma proteins.

Metabolism and Elimination

Carbidopa

Carbidopa is metabolized to two main metabolites (α-methyl-3-methoxy-4-hydroxyphenylpropionic acid and α-methyl-3,4-dihydroxyphenylpropionic acid). These 2 metabolites are primarily eliminated in the urine unchanged or as glucuronide conjugates. Unchanged carbidopa accounts for 30% of the total urinary excretion. The elimination half-life of carbidopa is approximately 2 hours.

Levodopa

Levodopa is mainly eliminated via metabolism by the aromatic amino acid decarboxylase (AAAD) and the catechol-O-methyl-transferase (COMT) enzymes. Other routes of metabolism are transamination and oxidation. The decarboxylation of levodopa to dopamine by AAAD is the major enzymatic pathway when no enzyme inhibitor is co-administered. O-methylation of levodopa by COMT forms 3-O-methyldopa. When administered with carbidopa, the elimination half-life of levodopa is approximately 1.5 hours (see Figure 1).

Drug Interaction Studies

COMT Inhibitors

Systemic exposure of levodopa is expected to increase in the presence of entacapone.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

In rat, oral administration of carbidopa-levodopa for two years resulted in no evidence of carcinogenicity. Duopa contains hydrazine, a degradation product of carbidopa. In published studies, hydrazine has been demonstrated to be carcinogenic in multiple animal species. Increases in liver (adenoma, carcinoma) and lung (adenoma, adenocarcinoma) tumors have been reported with oral administration of hydrazine in mouse, rat, and hamster.

Mutagenesis

Carbidopa was positive in the in vitro Ames test, in the presence and absence of metabolic activation, and the in vitro mouse lymphoma tk assay in the absence of metabolic activation but was negative in the in vivo mouse micronucleus assay.

In published studies, hydrazine was reported to be positive in in vitro genotoxicity (Ames, chromosomal aberration in mammalian cells, and mouse lymphoma tk) assays and in the in vivo mouse micronucleus assay.

Impairment of Fertility

In reproduction studies, no effects on fertility were observed in rats receiving carbidopa -levodopa.

Clinical Studies

The efficacy of Duopa was established in a randomized, double-blind, double-dummy, active-controlled, parallel group, 12-week study (Study 1) in patients with advanced Parkinson's disease who were levodopa-responsive and had persistent motor fluctuations while on treatment with oral immediate-release carbidopa-levodopa and other Parkinson's disease medications.

Patients were eligible for participation in the studies if they were experiencing 3 hours or more of “Off” time on their current Parkinson's disease drug treatment and they demonstrated a clear responsiveness to treatment with levodopa. Seventy-one (71) patients enrolled in the study and 66 patients completed the treatment (3 patients discontinued treatment because of adverse reactions, 1 patient for lack of effect, and 1 patient for non-compliance).

Patients enrolled in this study had a mean age of 64 years and disease duration of 11 years. Most patients (89%) were taking at least one concomitant medication for Parkinson’s disease (e.g., dopaminergic agonist, COMT-inhibitor, MAO-B inhibitor) in addition to oral immediate-release carbidopa-levodopa. Thirty nine percent of patients were taking two or more of such concomitant medications.

Patients were randomized to either Duopa and placebo capsules or placebo suspension and oral immediate-release carbidopa-levodopa 25/100 mg capsules. Patients in both treatment arms had a PEG-J device placement. Duopa or placebo-suspension was infused over 16 hours daily through a PEG-J tube via the CADD®-Legacy 1400 model ambulatory infusion pump. The mean daily levodopa dose was 1117 mg/day in the Duopa group and 1351 mg/day in the oral immediate-release carbidopa-levodopa group.

The clinical outcome measure in Study 1 was the mean change from baseline to Week 12 in the total daily mean “Off” time, based on a Parkinson's disease diary. The "Off" time was normalized to a 16-hour awake period, based on a typical person's waking day and the daily infusion duration of 16 hours. The mean score decrease (i.e., improvement) in “Off” time from baseline to Week 12 for Duopa was significantly greater (p=0.0015) than for oral immediate-release carbidopa-levodopa. Additionally, the mean score increase (i.e., improvement) in “On” time without troublesome dyskinesia from baseline to Week 12 was significantly greater (p=0.0059) for Duopa than for oral immediate-release carbidopa-levodopa. The treatment difference (Duopa – oral immediate release carbidopa-levodopa) for decrease in “Off” time was approximately 1.9 hours and the treatment difference for the increase in “On” time without troublesome dyskinesia was approximately 1.9 hours. Results of Study 1 are shown in Table 4.

How Supplied/Storage and Handling

How Supplied

Single-use cassettes containing 4.63 mg carbidopa (as 5 mg of the monohydrate) and 20 mg levodopa per mL of enteral suspension. Each cassette contains approximately 100 mL of suspension.

Carton of 7 Duopa cassettes: NDC 0074-3012-07

Storage and Handling

Store in freezer at -20oC (-4oF). Thaw in refrigerator at 2oC to 8oC (36oF to 46oF) prior to dispensing. Cassettes should be protected from light and kept in the carton prior to use.

Thawing instructions for pharmacies

  • Assign a 12 week “Use By” date based on the time the cartons are put into the refrigerator to thaw.
  • Fully thaw Duopa in the refrigerator prior to dispensing.
  • In order to ensure controlled thawing of Duopa, take the cartons containing the seven individual cassettes out of the transport box and separate the cartons from each other.
  • Thawing may take up to 96 hours when the cartons are taken out of the transport box.
  • Once the product has thawed, the individual cartons may be packed in a closer configuration within the refrigerator.

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (Medication Guide and Instructions for Use).

Administration Information

Ask patients if they have had any previous surgery in the upper part of their abdomen that may lead to difficulty in performing the gastrostomy or jejunostomy [see Dosage and Administration (2.3)].

Advise patients that foods that are high in protein may reduce the effectiveness of Duopa [see Drug Interactions (7.5) and Clinical Pharmacology (12.3)].

Interruption of Duopa Infusion

If the patient anticipates disconnecting the pump for a short period of time (less than 2 hours such as to swim, shower, or short medical procedure), no supplemental oral medication is needed, but the patient may be advised to take an extra-dose of Duopa before disconnecting. Instruct the patient to stop the continuous rate, turn off the pump, clamp the cassette tube, disconnect the tubing, and replace the red cap on the cassette tube. The Duopa cassette can remain attached to the pump until the tubing is reconnected. Refer the patient to the Patient Instructions for Use for additional information (i.e., changing the Duopa Cassette: disconnecting Steps 1-5 and reconnecting Steps 10-16).

Advise the patient to contact their healthcare provider and to take oral carbidopa-levodopa until the patient is able to resume Duopa infusion, if the patient will have prolonged interruption of therapy lasting more than 2 hours [see Dosage and Administration (2.4)].

Gastrointestinal and Gastrointestinal Procedure-Related Risks

Inform patients of the gastrointestinal procedure-related risks including bezoar, ileus, implant site erosion/ulcer, intestinal hemorrhage, intestinal ischemia, intestinal obstruction, intestinal perforation, pancreatitis, peritonitis, pneumoperitoneum, post-operative wound infection and sepsis. Advise patients of the symptoms of the above listed complications and instruct them to contact their healthcare provider if they experience any of these symptoms [see Warnings and Precautions (5.1)].

Falling Asleep during Activities of Daily Living and Somnolence

Alert patients to the potential sedating effects caused by Duopa, including somnolence and the possibility of falling asleep while engaged in activities of daily living. Because somnolence is a common adverse reaction with potentially serious consequences, patients should not drive a car, operate machinery, or engage in other potentially dangerous activities until they have gained sufficient experience with Duopa to gauge whether or not it affects their mental and/or motor performance adversely. Advise patients that if increased somnolence or episodes of falling asleep during activities of daily living (e.g., conversations, eating, driving a motor vehicle, etc.) are experienced at any time during treatment, they should not drive or participate in potentially dangerous activities until they have contacted their physician.

Advise patients of possible additive effects when patients are taking other sedating medications, alcohol, or other central nervous system depressants (e.g., benzodiazepines, antipsychotics, antidepressants, etc.) in combination with Duopa or when taking a concomitant medication that increases plasma levels of levodopa [see Warnings and Precautions (5.2)].

Orthostatic Hypotension

Advise patients that they may experience syncope and may develop hypotension with or without symptoms such as dizziness, nausea, syncope, and sometimes sweating while taking Duopa. Accordingly, caution patients against standing rapidly after sitting or lying down, especially if they have been doing so for prolonged periods and especially at the initiation of treatment with Duopa [see Warnings and Precautions (5.3)].

Hallucinations/Psychosis/Confusion

Inform patients that they may experience hallucinations (unreal visions, sounds, or sensations) and other symptoms of psychosis can occur while taking Duopa. Tell patients to report hallucinations, abnormal thinking, psychotic behavior or confusion to their healthcare provider promptly should they develop [see Warnings and Precautions (5.4)].

Impulse Control/Compulsive Behaviors

Advise patients that they may experience impulse control and/or compulsive behaviors while taking Duopa. Advise patients to inform their physician or healthcare provider if they develop new or increased gambling urges, sexual urges, uncontrolled spending, binge or compulsive eating, or other urges while being treated with Duopa [see Warnings and Precautions (5.5)].

Depression and Suicidality

Inform patients that they may develop depression or experience worsening of depression while taking Duopa. Instruct patients to contact their healthcare provider if they experience depression, worsening of depression, or suicidal thoughts [see Warnings and Precautions (5.6)].

Withdrawal-Emergent Hyperpyrexia and Confusion

Advise patients to contact their healthcare provider before stopping Duopa. Tell patients to inform their healthcare provider if they develop withdrawal symptoms such as fever, confusion, or severe muscle stiffness [see Warnings and Precautions (5.7)].

Dyskinesia

Inform patients that Duopa may cause or exacerbate pre-existing dyskinesias [see Warnings and Precautions (5.8)].

Neuropathy

Inform patients that neuropathy may develop or they may experience worsening neuropathy on Duopa, and to contact their healthcare provider if they develop any symptoms or features suggesting neuropathy [see Warnings and Precautions (5.9)].

Melanoma

Advise patients with Parkinson’s disease that they have a higher risk of developing melanoma. Advise patients to have their skin examined on a regular basis by a qualified healthcare provider (e.g., dermatologist) when using Duopa [see Warnings and Precautions (5.11)].

Nursing Mothers

Because of the possibility that carbidopa or levodopa may be excreted in human milk, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother [see Use in Specific Populations (8.3)].

MEDICATION GUIDE

Duopa (Do-oh-pa)

(carbidopa and levodopa) enteral suspension


Read this Medication Guide before you start using Duopa and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.

What is the most important information I should know about Duopa?

Duopa can cause serious side effects, including:

  • Stomach and intestine (gastrointestinal) problems and problems from the procedure you will need to have to receive Duopa (gastrointestinal procedure-related problems).

    Some of these problems may require surgery and may lead to death.

    • a blockage of your stomach or intestines (bezoar)
    • stopping movement through intestines (ileus)
    • drainage, redness, swelling, pain, feeling of warmth around the small hole in your stomach wall (stoma)
    • bleeding from stomach ulcers or your intestines
    • inflammation of your pancreas (pancreatitis)
    • air or gas in your abdominal cavity
    • skin infection around the intestinal tube, infection in your blood or abdominal cavity may occur, after surgery
    • stomach pain, nausea or vomiting
  • Tell your healthcare provider right away if you have any of the following symptoms of stomach and intestine problems and gastrointestinal procedure-related problems:
    • stomach (abdominal) pain
    • constipation that does not go away
    • nausea or vomiting
    • fever
    • blood in your stool or a dark tarry stool (melanotic stool)

You will need to have a procedure to make a small hole (called a “stoma”) in your stomach wall to place a gastro-jejunostomy tube (called a PEG-J tube) in an area of your small intestine called the jejunum. Duopa is delivered directly to your small intestine through this tube. Your healthcare provider will talk to you about the stoma procedure. Before the stoma procedure, tell your healthcare provider if you have ever had a surgery or problems with your stomach.

Talk to your healthcare provider about what you need to do to care for your stoma. After the procedure, you and your healthcare provider will need to regularly check the stoma for any signs of infection.

If your PEG-J tube becomes kinked, knotted, or blocked this may cause you to have worsening of your Parkinson’s symptoms or recurring movement problems (motor fluctuations). Call your healthcare provider if your Parkinson’s symptoms get worse or you have slow movement while you are treated with Duopa.

What is Duopa?

Duopa is a prescription medicine used for treatment of advanced Parkinson's disease. Duopa contains 2 medicines, carbidopa and levodopa.

Duopa should not be given to children (younger than 18 years).

Who should not use Duopa?

Do not use Duopa if you:

  • take a medicine called a nonselective Monoamine Oxidase (MAO) Inhibitor (such as phenelzine or tranylcypromine) or have taken a nonselective MAO Inhibitor within the last 14 days.
    Ask your healthcare provider or pharmacist if you are not sure if you take an MAO Inhibitor.

What should I tell my healthcare provider before using Duopa?

Before you use Duopa, tell your healthcare provider if you:

  • have or have had stomach ulcers or stomach surgery
  • have low blood pressure (hypotension) or if you feel dizzy or faint, especially when getting up from sitting or lying down
  • have had problems with fainting (syncope)
  • feel sleepy or have fallen asleep suddenly during the day
  • have or have had depression (feelings of hopelessness or sadness) or any mental problems
  • drink alcohol. Alcohol can increase the chance that Duopa will make you feel sleepy or fall asleep when you should be awake
  • have trouble controlling your muscles (dyskinesia)
  • have nerve problems (peripheral neuropathy)
  • have or have had heart problems, an abnormal heart rate or have had a heart attack in the past
  • have or have had a type of skin cancer called melanoma
  • have or have had high blood pressure (hypertension)
  • have eye problems that cause increased pressure in your eye (glaucoma)
  • have a history of attacks of suddenly falling asleep and without warning
  • have any other medical conditions
  • are pregnant or planning to become pregnant. It is not known if Duopa will harm your unborn baby
  • are breastfeeding or plan to breastfeed. Duopa can pass into your milk and may harm your baby. Talk to your healthcare provider about the best way to feed your baby if you take Duopa

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, herbal supplements.

Using Duopa with certain other medicines may affect each other and cause serious side effects.

Especially tell your healthcare provider if you take:

  • medicines used to treat high blood pressure (hypertension)
  • medicines used to treat depression called nonselective Monoamine Oxidase (MAO) Inhibitor (such as phenelzine or tranylcypromine) or have taken one within the last 14 days
  • dopamine D2 receptor antagonists (antipsychotics or metoclopramide), and isoniazid
  • iron or multivitamins with iron

Eating high protein foods may affect how Duopa works. Tell your healthcare provider if you change your diet.

Ask your healthcare provider or pharmacist for a list of these medicines or foods if you are not sure.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

How should I use Duopa?

  • Use Duopa exactly as your healthcare provider tells you to use it.
  • Your healthcare provider should show you how to use Duopa before you use it for the first time. Ask your healthcare provider or pharmacist if you have any questions.
  • Your prescribed dose of Duopa will be programmed into your pump by a healthcare provider and should only be changed by your healthcare provider or while you are with your healthcare provider.
  • Do not stop using Duopa or change your dose unless you are told to do so by your healthcare provider. Tell your healthcare provider if you develop withdrawal symptoms such as fever, confusion, or severe muscle stiffness.
  • Keep a supply of oral carbidopa-levodopa immediate release (IR) tablets with you in case you are unable to give your Duopa infusion.
  • Duopa is given continuously over 16 hours through a tube that is put into your stomach called a PEG-J. A small pump (CADD-Legacy 1400) is used to move Duopa from the medication cassette through your PEG-J tube.
  • Your Duopa dose has three parts:
    • a morning dose
    • a continuous dose
    • extra doses
  • Duopa can also be given for a short time (short-term) through a tube put into your nose called a naso-jejunal (NJ) tube.
  • The CADD-Legacy 1400 portable infusion pump should be used to give Duopa through your PEG-J tube. See the Instructions for Use that comes with your CADD-Legacy 1400 portable infusion pump for complete instructions on how to use the pump.
  • Duopa comes in a small plastic container (cassette) that you connect to the pump to get your medicine.
    • Each cassette can only be used 1 time. An opened cassette should not be reused.
    • The cassette should not be used for longer than 16 hours.
    • The cassette should be thrown away at the end of the infusion, even if there is some medicine still in the cassette.
  • Disconnect the pump from your PEG-J tube after the 16 hour dosing time is finished. Use a syringe filled with room temperature water to flush your PEG-J tube. See the “Instructions for Use” for more information about how to flush your PEG-J tube with a syringe.
  • After your daily Duopa infusion, you should take your usual night-time dose of oral carbidopa-levodopa tablets as prescribed.
  • If you stop your Duopa infusion for more than 2 hours during your 16 hour dosing time for any reason, call your healthcare provider and take oral carbidopa-levodopa as prescribed until you are able to restart your Duopa infusion.
  • If you stop your Duopa infusion for less than 2 hours, you do not need to take oral carbidopa-levodopa, but your healthcare provider may tell you to take an extra dose of Duopa.

What should I avoid while using Duopa?

  • Do not drive, operate machinery, or do other activities until you know how Duopa affects you. Sleepiness and falling asleep suddenly caused by Duopa can happen as late as 1 year after you start your treatment.

What are the possible side effects of Duopa?

Duopa may cause serious side effects, including:

  • See “What is the most important information I should know about Duopa?”
  • Falling asleep during normal daily activities. Duopa may cause you to fall asleep while you are doing daily activities such as driving, talking with other people, or eating.
    • You could fall asleep without any warning.
    • Some people using Duopa have had car accidents because they fell asleep while driving.
      Do not drive or operate machinery until you are sure how Duopa affects you.
      Tell your healthcare provider if you take other medicines that can make you sleepy such as sleep medicines, antidepressants, or antipsychotics.
  • Low blood pressure when you sit or stand up quickly. After you have been sitting or lying down, stand up slowly until you know how Duopa affects you. This may help reduce the following symptoms while you are using Duopa:
    • dizziness
    • nausea
    • sweating
    • fainting
  • Seeing things that are not there, hearing sounds or feeling sensations that are not real (hallucinations). Hallucinations can happen in people who use Duopa. Tell your healthcare provider if you have hallucinations.
  • Unusual urges. Some people taking certain medicines to treat Parkinson’s disease, including Duopa, have reported problems, such as gambling, compulsive eating, compulsive shopping, and increased sex drive.
    If you or your family members notice that you are having unusual urges or behaviors, talk to your healthcare provider.
  • Depression and suicide. Duopa can cause depression or make your depression worse. Pay close attention to sudden changes in your mood, behavior, thoughts, or feelings. Call your healthcare provider right away if you feel depressed or have thoughts of suicide.
  • Uncontrolled sudden movements (dyskinesia). If you have new dyskinesia, or your dyskinesia gets worse, tell your healthcare provider. This may be a sign that your dose of Duopa or other medicines to control your Parkinson’s disease may need to be adjusted.
  • Progressive weakness or numbness or loss of sensation in the fingers or feet (neuropathy).
  • Heart attack or other heart problems. Tell your healthcare provider if you have experienced increased blood pressure, a fast or irregular heartbeat or chest pain.
  • Skin cancer (melanoma). Parkinson's disease may be associated with a higher chance of having melanoma than people who do not have Parkinson’s disease. It is not known if the chance of having melanoma is higher because of the medicines used to treat Parkinson’s disease, like Duopa, or from the Parkinson’s disease. People who use Duopa should have their skin checked regularly for melanoma by a qualified healthcare professional.
  • Abnormal blood tests. Duopa may cause changes in certain blood tests, especially certain hormone and kidney function blood tests.
  • Worsening of the increased pressure in your eyes (glaucoma). The pressure in your eyes should be checked after starting Duopa.
  • The most common side effects of Duopa include:
    • swelling of legs and feet
    • nausea
    • high blood pressure (hypertension)
    • depression
    • mouth and throat pain

Call your healthcare provider or get medical care right away if you have any of the above symptoms. Your healthcare provider will tell you if you should stop treatment with Duopa and if needed, tell you how to discontinue Duopa.

Tell your healthcare provider if you have any side effect that bothers you or does not go away.

These are not all of the possible side effects of Duopa. For more information, ask your healthcare provider or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

How should I store Duopa?

  • Store Duopa in the refrigerator between 36ºF to 46ºF (2ºC to 8ºC). Do not freeze.
  • Use at room temperature. Take one Duopa cassette out of the carton and out of the refrigerator 20 minutes prior to use. Use the product at room temperature or you may not get the right amount of medication.
  • Protect the cassette from light and keep it in the carton before using.
  • Use Duopa before the expiration date printed on the cassette.

Keep Duopa and all medicines out of the reach of children.

Warnings

  • This operator’s manual should be used by clinicians only. Do not permit patients to have access to this manual, as the information contained would allow the patient complete access to all programming and operating functions. Improper programming could compromise patient treatment.
  • To avoid explosion hazard, do not use the pump in the presence of flammable anesthetics or explosive gases.
  • The CADD-Legacy® 1400 pump and medication cassette reservoir are designed for enteral delivery of medication only. They are NOT intended for IV or other parenteral routes of infusion.
  • Do not disclose to the patient the pump’s security codes or any other information that would allow the patient complete access to all programming and operating functions. Improper programming could compromise patient treatment.
  • Always have new batteries available for replacement. If power is lost, non-delivery of medication will occur.
  • If the pump is dropped or hit, the battery door or tabs may break. Do not use the pump if the battery door or tabs are damaged because the batteries will not be properly secured; this may result in loss of power and non-delivery of medication.
  • If a gap is present anywhere between the battery door and the pump housing, the door is not properly latched. If the battery door becomes detached or loose, the batteries will not be properly secured; this could result in loss of power and non-delivery of medication.
  • System delivery inaccuracies beyond the stated accuracy may occur as a result of back pressure or fluid resistance, which depends upon temperature, medication viscosity, catheter size, extension set tubing, flow rate, and orientation of the pump system.
  • Programming the pump at a delivery rate other than what is prescribed will cause over- or under-delivery of medication.
  • Clamp the fluid path tubing and/or disconnect the tubing from the enteral access device before removing the medication cassette reservoir from the pump to prevent unintended delivery of medication.
  • Use only approved Duopa medication cassette reservoirs to maintain pump accuracy and assure proper pump operations.
  • Use only extension sets approved for use with Duopa, paying particular attention to all warnings and cautions associated with their use.
  • Attach the cassette properly. The cassette is the part of the medication cassette reservoir that attaches to the pump. A detached or improperly attached cassette could result in unintended delivery of medication.
  • Do not prime the fluid path with the tubing connected to a patient as this could result in over-delivery of medication.
  • If the pump is dropped or hit, inspect the pump for damage. Do not use a pump that is damaged or is not functioning properly, as this could compromise patient treatment.
  • The use of power supplies and a remote dose cord other than those listed in the electromagnetic emissions declaration may result in increased emissions or decreased immunity of the pump.
  • The pump should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the user should verify normal operation of the pump in the configuration in which it is to be used.
  • There are potential health hazards associated with improper disposal of batteries, electronics, and contaminated (used) reservoirs and extension sets. Dispose of used batteries, reservoirs, extension sets and other used accessories, or a pump that has reached the end of its useful life, in an environmentally safe manner, and according to any regulations that may apply.

Cautions

  • Use only Smiths Medical accessories and replacement parts, as using other brands may adversely affect the operation of the pump.
  • Do not operate the pump at temperatures below 2°C (36°F) or above 40°C (104°F).
  • Do not store the pump at temperatures below -20°C (-4°F) or above 60°C (140°F). Do not store the pump with the medication cassette reservoir attached. Use the protective cassette provided.
  • Do not expose the pump to humidity levels below 20% or above 90% relative humidity.
  • Do not sterilize the pump or medication cassette reservoir as this could cause damage.
  • When the upstream occlusion sensor is turned off, the pump will not detect occlusions in the medication cassette reservoir. Periodically inspect the medication cassette reservoir for decreasing volume. Undetected occlusions could result in under- or non-delivery of medication.
  • Do not use rechargeable NiCd or nickel metal hydride (NiMH) batteries. Do not use carbon zinc (“heavy duty”) batteries. They do not provide sufficient power for the pump to operate properly.
  • Do not store the pump for prolonged periods of time with the batteries installed. Battery leakage could damage the pump.
  • Prior to starting medication delivery, inspect the fluid path for kinks, a closed clamp, or other obstruction. An undetected occlusion may result in under- or non-delivery of medication and/or nuisance alarms.
  • When you enter a new value, any lockout time already in effect will be cleared. An extra dose or morning dose could be requested and delivered immediately upon starting the pump, which may result in over-delivery of medication.
  • Do not immerse the pump in cleaning fluid or water. Do not allow solution to soak into the pump, accumulate on the keypad, or enter the battery compartment. Moisture buildup inside the pump may damage the pump.
  • Do not clean the pump with acetone, other plastic solvents, or abrasive cleaners, as damage to the pump may occur.
  • Do not expose the pump to ther­apeutic levels of ionizing radiation as permanent damage to the pump’s electronic circuitry may occur. The best procedure to fol­low is to remove the pump from the patient during therapeutic radia­tion sessions. If the pump must remain in the vicinity during a ther­apy session, it should be shielded, and its ability to function properly should be confirmed following treatment.
  • Do not expose the pump directly to ultrasound, as permanent damage to the electronic circuitry may occur.
  • Do not use the pump in the vicinity of magnetic resonance imaging (MRI) equipment as magnetic fields may adversely affect the operation of the pump. Remove the pump from the patient during MRI procedures and keep it at a safe distance from magnetic energy.
  • This pump may interfere with ECG equipment. Monitor ECG equipment carefully when using this pump.
  • CADD-Legacy® 1400 pumps are sealed units. A broken or damaged seal will, therefore, be considered conclusive evidence that the pump has been misused and/or altered, which voids any and all warranties. All service and repair of CADD-Legacy® 1400 pumps must be performed by Smiths Medical or its authorized agents.
  • Review programming screens when complete to make sure desired programming has been entered. Check to make sure unintended changes were not made to the morning dose, continuous rate, or extra dose volume. If unintended changes were made, go to the appropriate screen and program the desired value.

Pump Diagram

Description of the Keys, Display, and Features

AC Indicator Light

The green indicator light is on when you are using the AC adapter to power the pump.

Display

The liquid crystal display (LCD) shows programming information and messages. In this manual, the term “display” is synonymous with display panel or LCD.

Keypad

The keys on the keypad are described below. A key beeps when pressed if it is operable in the current lock level.

used to start and stop pump delivery; silences alarms.
used to enter (save) a new value in the pump’s memory when programming doses or pump settings or to clear values from record-keeping screens. It is also used to return from the biomed functions to the main screen (see Section 4).
used to fill the tubing with medication.
used to confirm and deliver the morning dose (typically used as a daily loading dose) when the pump is running. When the pump is stopped, it is used to view or change the pump’s current lock level. Lock levels are used to limit patient access to certain programming and operating functions. (See Lock Levels, this section.)
used to move from one programming screen to the next without changing the setting or value displayed; silences alarms.
used to “scroll up” or increase a value, or scroll through biomed function settings.
used to “scroll down” or decrease a value, or scroll through biomed function settings.
used to put the pump into a low power state when not in use or back into full power.
used by the patient to deliver a programmed amount of medication upon request (extra dose).

Power Jack

You may plug an AC adapter into the power jack as an alternate source of power. The indicator light on the front of the pump will illuminate when the AC adapter is in use.

Accessory Jack

The accessory jack is used for attaching accessory cables. See the instructions for use supplied with those accessories.

Medication Cassette Reservoir

The medication cassette reservoir is the single-use reservoir designed for use with the CADD-Legacy® 1400 pump. In this manual and on the pump’s display, the word “disposable” refers to the medication cassette reservoir. In AbbVie’s patient instructions for use, medication cassette reservoir is referred to as Duopa cassette.

Battery Compartment

Two AA batteries fit into the battery compartment. The AA batteries serve as the primary source of power, or as backup power when an AC adapter is in use.

Cassette Latch

The cassette latch attaches the cassette to the pump. The term “cassette” refers to the part of the medication cassette reservoir that attaches to the bottom of the pump. If the cassette becomes unlatched while the pump is running, delivery will stop and an alarm will occur. If the cassette becomes unlatched while the pump is stopped, an alarm will occur.

Other Features Not Shown

Upstream Occlusion Sensor: The pump contains an upstream occlusion sensor. This feature may be turned on or off (see Section 4, Biomed Functions). When the sensor is turned on, and an occlusion in the reservoir is detected, an alarm will sound, delivery will stop, and the display will show Upstream Occlusion.

CAUTION: When the upstream occlusion sensor is turned off, the pump will not detect occlusions in the medication cassette reservoir. Periodically inspect the medication cassette reservoir for decreasing volume. Undetected occlusions could result in under- or non-delivery of medication.

Downstream Occlusion Sensor: The pump contains a downstream occlusion sensor. When a downstream occlusion (between the pump and the patient) is detected, an alarm will sound, delivery will stop, and the display will show High Pressure.

Reservoir Volume Alarm: The reservoir volume alarm indicates when the volume of medication in the medication cassette reservoir is low or depleted. Each time you change the medication cassette reservoir, you may reset the reservoir volume to the originally programmed value. Then, as medication is delivered, the reservoir volume automatically decreases. When the pump calculates that 5 ml remain in the medication cassette reservoir, beeps sound and ResVol Low appears on the main screen. This alarm recurs at every subsequent decrease of 1 ml until the reservoir volume reaches 0 ml, at which point the pump stops and the reservoir volume empty alarm sounds.

NOTE: The default setting for Reservoir Volume is Not in Use. The reservoir volume alarm is activated only when a value is programmed into the Reservoir Volume screen. Programming a reservoir volume value is not required for general use, but is available at provider discretion.

The Main Screen

The main screen is the starting point for programming or viewing the pump’s settings.

If no keys are pressed for 2 minutes, the display reverts to the main screen. When the two AA batteries are low, LowBat appears on the main screen.

*Does not appear on the main screen if reservoir volume is programmed to Not In Use.

Lock Levels

Lock levels are used to limit patient access to certain programming and operating functions. The table on the next page lists the functions that are accessible in lock level 0 (LL0), lock level 1 (LL1), and lock level 2 (LL2). When a function is accessible, the key associated with the function beeps when pressed. If a function is not accessible, the pump ignores the key press and a beep does not sound. Section 2, Pump Setup and Programming, describes how to change the lock level.

Security Codes

2.0 Pump Setup and Programming

Installing or Replacing the Batteries

Use new, AA alkaline batteries such as DURACELL® or EVEREADY® ENERGIZER® batteries to power the pump. The pump retains all programmed values while the batteries are removed.

Dispose of used batteries in an environmentally safe manner, and according to any regulations which may apply.

WARNING:
  • Always have new batteries available for replacement. If power is lost, non-delivery of medication will occur, which could compromise patient treatment.
  • If the pump is dropped or hit, the battery door or tabs may break. Do not use the pump if the battery door or tabs are damaged because the batteries will not be properly secured; this may result in loss of power and non-delivery of medication, which could compromise patient treatment.
CAUTION: Do not use rechargeable NiCd or nickel metal hydride (NiMH) batteries. Do not use carbon zinc (“heavy duty”) batteries. They do not provide sufficient power for the pump to operate properly.

In order to install or replace the batteries, be sure the pump is Stopped. Then, follow these steps:

1. Push down and hold the arrow button while sliding the door off.

2. Remove the used batteries. Pulling on the end of the battery strap will make battery removal easier.

3. Install the new batteries in the compartment, making sure the battery strap is positioned correctly under the batteries.

NOTE:

  • Be sure to match the polarity markings of the new batteries (+ and –) with those labeled in the battery compartment. If you put the batteries in backwards, the display will remain blank, and you will not hear a beep.
  • Use two new, AA alkaline batteries to power the pump. You may use any alkaline batteries, including DURACELL® Alkaline and EVEREADY® ENERGIZER® Alkaline, for example.

4. Place the battery door over the battery compartment and slide the door closed.

5. Ensure that the door is latched by trying to remove the door without pressing the arrow button.

NOTE: The power-up sequence will start, the pump will go through an electronic self-test, and the pump will beep 6 times at the end of the power-up sequence. All of the display indicators, the software revision, and each parameter will appear briefly.

WARNING: If a gap is present anywhere between the battery door and the pump housing, the door is not properly latched. If the battery door becomes detached or loose, the batteries will not be properly secured; this could result in loss of power and non-delivery of medication, which could compromise patient treatment.

6. Resume operation of the current program by pressing and holding to start the pump or proceed to program the pump.

NOTE:

  • The life of the batteries is dependent on the amount of medication delivered, delivery rate, battery age, and the temperature.
  • At the rate of 100 ml per day, alkaline batteries will usually last about 7 days.
  • The power of the batteries will be quickly depleted at temperatures below 10°C (50°F).
CAUTION: Do not store the pump for prolonged periods of time with the batteries installed. Battery leakage could damage the pump.

Watching Power Up

When you install the batteries, the pump will start its power up sequence during which it performs self-tests and displays programmed values. Watch for the following:

  • Pump model number and last error code (“LEC”) if any, will appear. (If an error code appears, the pump should be removed from use and returned for service.)
  • The software revision will appear.
  • The display will turn on, showing a series of blocks. Look for any blank areas, which would indicate a faulty display.
  • The display will turn off briefly.
  • The pump’s program screens will appear, followed by the current lock level setting. The pump will beep after each screen. If messages appear, see Messages and Alarms Table, Section 5 for further explanation and instruction.
  • When power up is complete, 6 beeps will sound, and the pump will be stopped on the main screen.

NOTE: To move quickly through the power-up screens, press repeatedly. To skip the automatic review entirely, pressIf you attempt to skip screens before the pump is powered up, it will not respond.

  2. Wipe the entire surface dry with another soft, lint-free cloth. Allow the pump to dry completely before use.

Cleaning the Battery Contacts

Routinely clean the battery contacts, possibly as part of the preventative maintenance cycle, to remove buildup of foreign material on the contacts.

Use the following to clean the battery contacts:

  • Cotton swab wetted with Isopropyl Alcohol (70% minimum)

    NOTE: Do not use an alcohol formulation that contains components other than alcohol and water.

    OR
  • Pre-moistened alcohol swab
  1. Using a swab wetted with alcohol, rub the entire battery contact for a minimum of 10 back and forth cycles (20 total wipes over the contact).
  2. Using a clean surface of the swab, repeat process for second battery contact.
  3. Using a clean swab wetted with alcohol, rub each battery contact again, a minimum of 4 back and forth cycles (8 total wipes over the contact).
  4. Allow the contacts to dry completely before use.

Exposure to Radiation, Ultrasound, Magnetic Resonance Imaging (MRI), or Use near ECG Equipment

CAUTION:
  • Do not expose the pump to therapeutic levels of ionizing radiation as permanent damage to the pump’s electronic circuitry may occur. The best procedure to follow is to remove the pump from the patient during therapeutic radiation sessions. If the pump must remain in the vicinity during a therapy session, it should be shielded, and its ability to function properly should be confirmed following treatment.
  • Do not expose the pump directly to ultrasound, as permanent damage to the electronic circuitry may occur.
  • Do not use the pump in the vicinity of magnetic resonance imaging (MRI) equipment as magnetic fields may adversely affect the operation of the pump. Remove the pump from the patient during MRI procedures and keep it at a safe distance from magnetic energy.
  • This pump may interfere with ECG equipment. Monitor ECG equipment carefully when using this pump.

Safety Features and Fault Detection

Hardware Safety Features

Key hardware safety features include a watchdog timer circuit, motor driver and motor watchdog circuits, and a voltage detector circuit. Each safety circuit performs a unique function to insure the overall safety of the device.

Watchdog Timer Circuit

The microprocessor must send an appropriate signal to the watchdog circuit at least once per second. If the microprocessor does not, the watchdog circuit will time out and shut down the pump controller.

Watchdog timer circuitry is provided to monitor the status of the microprocessor and disable the motor and enable the audible alarm if the microprocessor fails to function properly. The microprocessor must strobe the watchdog circuit at least once every second in order to prevent the watchdog from performing its reset function. The reset output from the watchdog circuit is a pulse output. This acts to “jump startˮ the microprocessor. This unique feature allows the microprocessor to test the watchdog circuit on every power-up.

By setting a flag in the memory and not strobing the watchdog, the microprocessor can force a watchdog time-out. After being reset, the microprocessor checks the status flag to see if this was a time-out test. If so, the microprocessor continues normal power-up activities. If the reset occurred when the microprocessor was not expecting it, the microprocessor traps the event, sounds the audible alarm and displays an error message on the LCD.

Motor Driver/Motor Watchdog Circuit

Motor drive circuitry is composed of a series of power FET transistors, passive components, and 2 voltage comparators. Built into the motor drive circuitry is an RC timer which times how long the motor runs each time it is turned on. If the motor runs for more than an average of 3 seconds, the circuit will time out and disable the motor. A unique feature of this circuit is that control lines to and from the microprocessor circuit allow the microprocessor to perform a complete functional test of the motor drive circuit without running the motor. The microprocessor performs this test function every several minutes to assure its continued functionality. An input from the watchdog circuit prevents motor operation if the watchdog timer expires. The software verifies this function during the watchdog test described above.

Voltage Detector Circuit

Low voltage detection is performed by part of the watchdog circuit and by the microprocessor via software. Three low voltage levels are detected. The first 2 levels are detected by software and the third by hardware. The first level to be reached is the low battery warning threshold which occurs when the battery voltage decays to a nominal value of 2.4 volts when the motor is off or 1.8 volts when the motor is active. An analog to digital converter (ADC) built into the microprocessor allows the microprocessor, via software, to monitor the battery voltage. At the low battery warning threshold, the microprocessor enables a periodic series of beeps and displays a low battery warning message on the LCD. As the voltage operating the motor reaches a nominal value of 4.75 volts, the software disables delivery, places a battery depleted message on the LCD, and enables a constant two tone audible alarm. When the battery voltage decays to a nominal value of 1.0 volts, a hardware reset circuit is triggered which places the microprocessor in reset. This prevents ambiguous microprocessor operation when the battery voltage continues to decay. The hardware reset continues until the battery is completely discharged or until it is removed. Once the pump controller goes into low battery shutdown, only replacing the depleted batteries with new ones will clear the condition.

Software Safety Features

Hardware-related Software Safety Features

Program Memory Check

At power up and at regular intervals thereafter, the program memory is tested by calculating a cyclic redundancy code (CRC) on the program and then comparing it with the CRC stored with the program.

If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

RAM Memory Check

At power up, the random access memory is checked. A series of bit patterns is written to and read from each address in the RAM. If the read data is different from the written data, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Motor Circuit Check

At power up and at regular intervals thereafter, the motor circuit is checked to ensure that no power is being applied to the motor unless the motor is actually on. If the software detects power being applied to the motor at any other time, it will sound a continuous two-tone audible alarm and will no longer attempt to deliver medication. During every pump activation, the software checks to see whether the motor completes one activation. If the motor fails to turn, or fails to complete a cycle, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Keyboard Encoder Check

Every time the software receives data from the keyboard encoder, it is checked. If the data is not a valid key press, the software will disregard the key press. The keyboard is designed with redundant switches for , , and . The software must detect that both switches are activated before taking any action.

Data Handling Software Safety Features

Data Stored in RAM

Before use, data associated with delivery and stored in RAM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Stored in EEPROM

Before use, data associated with delivery and stored in EEPROM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Stored in NOVRAM

Before use, data associated with delivery and stored in NOVRAM is tested by calculating a CRC on the data and then comparing it with the CRC stored with the data. If the stored and calculated CRCs do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Data Used in Calculations

Calculations on data used in some way to control the delivery of medication are performed redundantly.

The two calculated values are then compared. If the two values do not match, the software will display a system fault screen, turn on a continuous two-tone audible alarm, and stop all medication delivery.

Timer Data Registers

The data in the real time clock is checked at regular intervals. If the data is not reasonable, the software will turn on a continuous two-tone audible alarm and stop all medication delivery.

Annual Functional Inspection

Smiths Medical recommends annual functional inspections and tests on the CADD-Legacy® 1400 pump. Contact Smiths Medical to coordinate return and inspection of the pump.
