Titration of Soliqua 100/33
- After starting with the recommended dosage of Soliqua 100/33, [see Dosage and Administration (2.2)], titrate the dosage upwards or downwards by two to four units (see Table 2) every week based on the patient's metabolic needs, blood glucose monitoring results, and glycemic control goal until the desired fasting plasma glucose is achieved.
- To minimize the risk of hypoglycemia or hyperglycemia, additional titration may be needed with changes in physical activity, meal patterns (i.e., macronutrient content or timing of food intake), or renal or hepatic function; during acute illness; or when used with other medications [see Warnings and Precautions (5.4) and Drug Interactions (7)].
|Self-Monitored Fasting Plasma Glucose||Soliqua 100/33 Dosage Adjustment|
|Above target range||+2 units (2 units of insulin glargine and 0.66 mcg of lixisenatide) to +4 units (4 units insulin glargine and 1.32 mcg lixisenatide)|
|Within target range||0 units|
|Below target range||-2 units (2 units of insulin glargine and 0.66 mcg of lixisenatide) to -4 units (4 units of insulin glargine and 1.32 mcg lixisenatide)|
Instruct patients who miss a dose of Soliqua 100/33 to resume the once-daily regimen as prescribed with the next scheduled dose. Do not administer an extra dose or increase the dose to make up for the missed dose.
Important Administration Instructions
- The Soliqua 100/33 prefilled pen is for single-patient-use only [see Warnings and Precautions (5.3)].
- Train patients on proper use and injection technique before initiating Soliqua 100/33.
- Always check the Soliqua 100/33 label before administration [see Warnings and Precautions (5.5)].

- Do not split the dose of Soliqua 100/33.
Dosage Forms and Strengths
Soliqua 100/33 injection: 100 units insulin glargine per mL and 33 mcg lixisenatide per mL is available as a clear, colorless to almost colorless solution in a 3 mL prefilled, disposable, single-patient-use SoloStar® pen.
Soliqua 100/33 is contraindicated:
- During episodes of hypoglycemia [see Warnings and Precautions (5.6)].
- In patients with hypersensitivity to Soliqua 100/33, either of the active drug substances (insulin glargine or lixisenatide), or any of its excipients. Hypersensitivity reactions including anaphylaxis have occurred with both lixisenatide and insulin glargine [see Warnings and Precautions (5.1) and Adverse Reactions (6.1)].
Warnings and Precautions
Anaphylaxis and Serious Hypersensitivity Reactions
In clinical trials of lixisenatide, a component of Soliqua 100/33, there have been cases of anaphylaxis (frequency of 0.1% or 10 cases per 10,000 patient-years) and other serious hypersensitivity reactions including angioedema. Severe, life-threatening, generalized allergic reactions, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock can occur with insulins, including insulin glargine, a component of Soliqua 100/33 [see Adverse Reactions (6.1)].
Inform and closely monitor patients with a history of anaphylaxis or angioedema with another GLP-1 receptor agonist for allergic reactions, because it is unknown whether such patients will be predisposed to anaphylaxis with lixisenatide. Soliqua 100/33 is contraindicated in patients with known hypersensitivity to lixisenatide or insulin glargine [see Contraindications (4)]. If a hypersensitivity reaction occurs, the patient should discontinue Soliqua 100/33 and promptly seek medical attention.
Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been reported postmarketing in patients treated with GLP-1 receptor agonists. In clinical trials of lixisenatide, a component of Soliqua 100/33, there were 21 cases of pancreatitis among lixisenatide-treated patients and 14 cases in comparator-treated patients (incidence rate of 21 vs 17 per 10,000 patient-years). Lixisenatide cases were reported as acute pancreatitis (n=3), pancreatitis (n=12), chronic pancreatitis (n=5), and edematous pancreatitis (n=1). Some patients had risk factors for pancreatitis, such as a history of cholelithiasis or alcohol abuse.
After initiation of Soliqua 100/33, observe patients carefully for signs and symptoms of pancreatitis (including persistent severe abdominal pain, sometimes radiating to the back and which may or may not be accompanied by vomiting). If pancreatitis is suspected, promptly discontinue Soliqua 100/33 and initiate appropriate management. If pancreatitis is confirmed, restarting Soliqua 100/33 is not recommended. Consider antidiabetic therapies other than Soliqua 100/33 in patients with a history of pancreatitis.
Never Share a Soliqua 100/33 Prefilled Pen Between Patients
Soliqua 100/33 prefilled pens must never be shared between patients, even if the needle is changed. Sharing of the pen poses a risk for transmission of blood-borne pathogens.
Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen
Changes in Soliqua 100/33 regimen may affect glycemic control and predispose to hypoglycemia or hyperglycemia. These changes should be made cautiously and only under close medical supervision, and the frequency of blood glucose monitoring should be increased. Adjustments in concomitant oral antidiabetic treatment may be needed. When converting from basal insulin therapy or a GLP-1 receptor agonist to Soliqua 100/33 follow dosing recommendations [see Dosage and Administration (2.2, 2.3)].
Overdose Due to Medication Errors
Soliqua 100/33 contains two drugs: insulin glargine and lixisenatide. Administration of more than 60 units of Soliqua 100/33 daily can result in overdose of the lixisenatide component. Do not exceed the 20 mcg maximum recommended dose of lixisenatide or use with other glucagon-like peptide-1 receptor agonists.
Accidental mix-ups between insulin products have been reported. To avoid medication errors between Soliqua 100/33 (an insulin-containing product) and other insulins, instruct patients to always check the insulin label before each injection.
Hypoglycemia is the most common adverse reaction associated with insulin-containing products, including Soliqua 100/33 [see Adverse Reactions (6.1)]. Severe hypoglycemia can cause seizures, may be life-threatening or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery). Soliqua 100/33 (an insulin-containing product), or any insulin, should not be used during episodes of hypoglycemia [see Contraindications (4)].
Hypoglycemia can happen suddenly and symptoms may differ in each individual and change over time in the same individual. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using medications that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions (7.1)], or in patients who experience recurrent hypoglycemia.
Risk Factors for Hypoglycemia
The risk of hypoglycemia generally increases with intensity of glycemic control. The risk of hypoglycemia after an injection is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulin-containing preparations, the glucose lowering effect time course of Soliqua 100/33 may vary in different individuals or at different times in the same individual and depends on many conditions, including the area of injection as well as the injection-site blood supply and temperature [see Clinical Pharmacology (12.2)].
Other factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to coadministered medication [see Drug Interactions (7.1)]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6, 8.7)].
Risk Mitigation Strategies for Hypoglycemia
Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended.
The long-acting effect of the insulin glargine component of Soliqua 100/33 may delay recovery from hypoglycemia.
Acute Kidney Injury
Acute kidney injury and worsening of chronic renal failure, which may sometimes require hemodialysis, has been reported postmarketing in patients treated with GLP-1 receptor agonists, such as lixisenatide, a component of Soliqua 100/33. Some of these events were reported in patients without known underlying renal disease. A majority of the reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration.
Monitor renal function when initiating or escalating doses of Soliqua 100/33 in patients with renal impairment and in patients reporting severe gastrointestinal reactions. Advise patients of the potential risk of dehydration due to gastrointestinal adverse reactions and take precautions to avoid fluid depletion. Soliqua 100/33 is not recommended in patients with end-stage renal disease [see Use in Specific Populations (8.6)].
Patients may develop antibodies to insulin and lixisenatide, components of Soliqua 100/33, following treatment. A pooled analysis of studies of lixisenatide-treated patients showed that 70% were antibody positive at Week 24. In the subset of patients (2.4%) with the highest antibody concentrations (>100 nmol/L), an attenuated glycemic response was observed. A higher incidence of allergic reactions and injection-site reactions occurred in antibody positive patients [see Warnings and Precautions (5.1), Adverse Reactions (6.2)].
If there is worsening glycemic control or failure to achieve targeted glycemic control, significant injection-site reactions or allergic reactions, alternative antidiabetic therapy should be considered.
All insulin-containing products, including Soliqua 100/33, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia if indicated (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).
Fluid Retention and Heart Failure with Concomitant Use of PPAR-gamma Agonists
Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin-containing products, including Soliqua 100/33. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin-containing products, including Soliqua 100/33, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered.
There have been no clinical studies establishing macrovascular risk reduction with Soliqua 100/33.
The following adverse reactions are discussed elsewhere:
- Anaphylaxis and Serious Hypersensitivity Reactions [see Warnings and Precautions (5.1)]
- Pancreatitis [see Warnings and Precautions (5.2)]
- Hypoglycemia [see Warnings and Precautions (5.6)]
- Acute Kidney Injury [see Warnings and Precautions (5.7)]
- Hypokalemia [see Warnings and Precautions (5.9)]
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice.
The safety of Soliqua 100/33 (n=834, with a mean treatment duration of 203 days) has been evaluated in two clinical studies (30 weeks duration) in type 2 diabetes patients. The studies, Study A and B [see Clinical Studies (14)], had the following characteristics: mean age was approximately 59 years; approximately 50% were male, 90% were Caucasian, 6% were Black or African American, and 18% were Hispanic. The mean duration of diabetes was 10.3 years, mean HbA1c at screening for Study A was 8.2 and Study B was 8.5. The mean BMI at baseline was 32 kg/m2. Baseline eGFR was ≥60 mL/min in 87.2% of the pooled study population and mean baseline eGFR was 83.0 mL/min/1.73 m2.

Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, and insulin-containing products including Soliqua 100/33 [see Warnings and Precautions (5.6)]. The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for Soliqua 100/33 with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice.
In the Soliqua 100/33 program, severe hypoglycemia was defined as an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions and documented symptomatic hypoglycemia was defined as an event with typical symptoms of hypoglycemia accompanied by a self-monitored plasma glucose value equal to or less than 70 mg/dL (see Table 4).
No clinically important differences in risk of severe hypoglycemia between Soliqua 100/33 and comparators were observed in clinical trials.
|Severe symptomatic hypoglycemia* (%)||0||1.1|
|Hypoglycemia (self-monitored plasma glucose <54 mg/dL) (%)||8.1||17.8|
Gastrointestinal Adverse Reactions
Gastrointestinal adverse reactions are the most commonly observed adverse reaction in patients using lixisenatide. Gastrointestinal adverse reactions occur more frequently at the beginning of Soliqua 100/33 therapy. Gastrointestinal adverse reactions including nausea, diarrhea, vomiting, constipation, dyspepsia, gastritis, abdominal pain, flatulence, gastroesophageal reflux disease, abdominal distension, and decreased appetite have been reported in patients treated with Soliqua 100/33.
In Study A, vomiting was 6.4% in the lixisenatide-treated patients versus 3.2% in the Soliqua 100/33–treated patients and 1.5% in the insulin glargine–treated patients; nausea was 24% in the lixisenatide-treated patients versus 9.6% in the Soliqua 100/33–treated patients, and 3.6% in the insulin glargine–treated patients.
Administration of insulin subcutaneously, including Soliqua 100/33, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) in some patients [see Dosage and Administration (2.5)].
Anaphylaxis and Hypersensitivity
In the lixisenatide development program anaphylaxis cases were adjudicated. Anaphylaxis was defined as a skin or mucosal lesion of acute onset associated with at least 1 other organ system involvement. Symptoms such as hypotension, laryngeal edema or severe bronchospasm could be present but were not required for the case definition. More cases adjudicated as meeting the definition for anaphylaxis occurred in lixisenatide-treated patients (incidence rate of 0.2% or 16 cases per 10,000 patient years) than placebo-treated patient (incidence rate of 0.1% or 7 cases per 10,000 patient years).
Allergic reactions (such as anaphylactic reaction, angioedema, and urticaria) adjudicated as possibly related to the study medication were observed more frequently in lixisenatide-treated patients (0.4%) than placebo-treated patients (0.2%) [see Warnings and Precautions (5.1)].
Severe, life-threatening, generalized allergy, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock may occur with any insulin, including Soliqua 100/33, and may be life threatening.
As with any insulin or GLP-1 receptor agonist–containing product, patients taking Soliqua 100/33 may experience injection-site reactions, including injection-site hematoma, pain, hemorrhage, erythema, nodules, swelling, discoloration, pruritus, warmth, and injection-site mass. In the clinical program the proportion of injection-site reactions occurring in patients treated with Soliqua 100/33 was 1.7%.
Insulin Initiation and Intensification of Glucose Control
Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy.
Some patients taking insulin glargine, a component of Soliqua 100/33 have experienced sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
Weight gain can occur with insulin-containing products, including Soliqua 100/33, and has been attributed to the anabolic effects of insulin.
As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Soliqua 100/33 in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
After 30 weeks of treatment with Soliqua 100/33 in two phase 3 trials, the incidence of formation of anti-insulin glargine antibodies was 21.0% and 26.2%. In approximately 93% of the patients, anti-insulin glargine antibodies showed cross-reactivity to human insulin. The incidence of formation of anti-lixisenatide antibodies was approximately 43%.
In the pool of 9 placebo-controlled studies, 70% of patients exposed to lixisenatide tested positive for anti-lixisenatide antibodies during the trials. In the subset of patients (2.4%) with the highest antibody concentrations (>100 nmol/L), an attenuated glycemic response was observed. A higher incidence of allergic reactions and injection-site reactions occurred in antibody positive patients [see Warnings and Precautions (5.8)].
Anti-lixisenatide antibody characterization studies have demonstrated the potential for development of antibodies cross-reactive with endogenous GLP-1 and glucagon, but their incidence has not been fully determined and the clinical significance of these antibodies is not currently known.
No information regarding the presence of neutralizing antibodies is currently available.
Medications that Can Affect Glucose Metabolism
A number of medications affect glucose metabolism and may require dose adjustment of Soliqua 100/33 and particularly close monitoring.
|Drugs That May Increase the Risk of Hypoglycemia|
|Drugs:||Antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, propoxyphene, salicylates, somatostatin analogs (e.g., octreotide), and sulfonamide antibiotics.|
|Intervention:||Dose reductions and increased frequency of glucose monitoring may be required when Soliqua 100/33 is coadministered with these drugs.|
|Drugs That May Decrease the Blood Glucose Lowering Effect of Soliqua 100/33|
|Drugs:||Atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), and thyroid hormones.|
|Intervention:||Dose increases and increased frequency of glucose monitoring may be required when Soliqua 100/33 is coadministered with these drugs.|
|Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of Soliqua 100/33|
|Drugs:||Alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia.|
|Intervention:||Dose adjustment and increased frequency of glucose monitoring may be required when Soliqua 100/33 is coadministered with these drugs.|
|Drugs That May Blunt Signs and Symptoms of Hypoglycemia|
|Drugs:||Beta-blockers, clonidine, guanethidine, and reserpine.|
|Intervention:||Increased frequency of glucose monitoring may be required when Soliqua 100/33 is coadministered with these drugs.|
Effects of Delayed Gastric Emptying on Oral Medications
Lixisenatide-containing products, including Soliqua 100/33, delay gastric emptying which may reduce the rate of absorption of orally administered medications. Use caution when coadministering oral medications that have a narrow therapeutic ratio or that require careful clinical monitoring. These medications should be adequately monitored when concomitantly administered with lixisenatide. If such medications are to be administered with food, patients should be advised to take them with a meal or snack when lixisenatide is not administered.
- Antibiotics, acetaminophen, or other medications that are particularly dependent on threshold concentrations for efficacy or for which a delay in effect is undesirable should be administered at least 1 hour before Soliqua 100/33 injection [see Clinical Pharmacology (12.3)].
- Oral contraceptives should be taken at least 1 hour before Soliqua 100/33 administration or 11 hours after [see Clinical Pharmacology (12.3)].
USE IN SPECIFIC POPULATIONS
Based on animal reproduction studies, there may be risks to the fetus from exposure to lixisenatide, a component of Soliqua 100/33, during pregnancy. Soliqua 100/33 should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The limited available data with Soliqua 100/33 and lixisenatide in pregnant women are not sufficient to inform a drug-associated risk of major birth defects and miscarriage. Published studies with insulin glargine use during pregnancy have not reported a clear association with insulin glargine and major birth defect or miscarriage risk [see Data]. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations].
Lixisenatide administered to pregnant rats and rabbits during organogenesis was associated with visceral closure and skeletal defects at systemic exposures that decreased maternal food intake and weight gain during gestation, and that are 1-time and 6-times higher than the 20 mcg/day highest clinical dose, respectively, based on plasma AUC [see Data].
The estimated background risk of major birth defects is 6%–10% in women with pregestational diabetes with a HbA1c >7 and has been reported to be as high as 20%–25% in women with a HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%–4% and 15%–20%, respectively.
Disease-associated maternal and/or embryo/fetal risk
Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, still birth, and macrosomia related morbidity.
Published data do not report a clear association with insulin glargine and major birth defects, miscarriage, or adverse maternal or fetal outcomes when insulin glargine is used during pregnancy. However, these studies cannot definitely establish the absence of any risk because of methodological limitations including small sample size and some lacking comparator groups.
Animal reproduction studies were not conducted with the combined products in Soliqua 100/33. The following data are based on studies conducted with the individual components of Soliqua 100/33.
In pregnant rats receiving twice daily subcutaneous doses of 2.5, 35, or 500 mcg/kg during organogenesis (gestation day 6 to 17), fetuses were present with visceral closure defects (e.g., microphthalmia, bilateral anophthalmia, diaphragmatic hernia) and stunted growth. Impaired ossification associated with skeletal malformations (e.g., bent limbs, scapula, clavicle, and pelvis) were observed at ≥2.5 mcg/kg/dose, resulting in systemic exposure that is 1-time the 20 mcg/day clinical dose, based on plasma AUC. Decreases in maternal body weight, food consumption, and motor activity were observed concurrent with the adverse fetal findings, which confounds the interpretation of relevance of these malformations to the human risk assessment. Placental transfer of lixisenatide to developing rat fetuses is low with a concentration ratio in fetal/maternal plasma of 0.1%.
In pregnant rabbits receiving twice daily subcutaneous doses of 2.5, 25, 250 mcg/kg during organogenesis (gestation day 6 to 18), fetuses were present with multiple visceral and skeletal malformations, including closure defects, at ≥5 mcg/kg/day or systemic exposures that are 6-times the 20 mcg/day highest clinical dose, based on plasma AUC. Decreases in maternal body weight, food consumption, and motor activity were observed concurrent with the fetal findings, which confounds the interpretation of relevance of these malformations to the human risk assessment. Placental transfer of lixisenatide to developing rabbit fetuses is low with a concentration ratio in fetal/maternal plasma of ≤0.3%. In a second study in pregnant rabbits, no drug-related malformations were observed from twice daily subcutaneous doses of 0.15, 1.0, and 2.5 mcg/kg administered during organogenesis, resulting in systemic exposures up to 9-times the clinical exposure at 20 mcg/day, based on plasma AUC.
In pregnant rats given twice daily subcutaneous doses of 2, 20, or 200 mcg/kg from gestation day 6 through lactation, decreases in maternal body weight, food consumption, and motor activity were observed at all doses. Skeletal malformations and increased pup mortality were observed at 400 mcg/kg/day, which is approximately 200-times the 20 mcg/day clinical dose based on mcg/m2.
Subcutaneous reproduction and teratology studies have been performed with insulin glargine and regular human insulin in rats and Himalayan rabbits. Insulin glargine was given to female rats before mating, during mating, and throughout pregnancy at doses up to 0.36 mg/kg/day, which is approximately 2-times the recommended human subcutaneous high dose of 60 units/day (0.0364 mg/kg/day), based on mg/m2. In rabbits, doses up to 0.072 mg/kg/day, which is approximately 1-times the maximum recommended human subcutaneous dose of 60 units/day (0.0364 mg/kg/day), based on mg/m2, were administered during organogenesis. The effects of insulin glargine did not generally differ from those observed with regular human insulin in rats or rabbits. However, in rabbits, five fetuses from two litters of the high-dose group exhibited dilation of the cerebral ventricles. Fertility and early embryonic development appeared normal.
There is no information regarding the presence of lixisenatide and insulin glargine in human milk, the effects on the breastfed infant, or the effects on milk production. Endogenous insulin is present in human milk. Lixisenatide is present in rat milk [see Data].
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Soliqua 100/33 and any potential adverse effects on the breastfed child from Soliqua 100/33 or from the underlying maternal condition.
A study in lactating rats showed low (9.4%) transfer of lixisenatide and its metabolites into milk and negligible (0.01%) levels of unchanged lixisenatide peptide in the gastric contents of weaning offspring.
Safety and effectiveness of Soliqua 100/33 have not been established in pediatric patients below 18 years of age.
Of the total number of subjects (n=834) in controlled clinical studies of patients with type 2 diabetes, who were treated with Soliqua 100/33, 25.2% (n=210) were ≥65 years of age and 4% (n=33) were ≥75 years of age. No overall differences in effectiveness and safety were observed in the subgroup analyses across the age groups.
Nevertheless, caution should be exercised when Soliqua 100/33 is administered to geriatric patients. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in the elderly.
Frequent glucose monitoring and dose adjustment may be necessary for Soliqua 100/33 in patients with renal impairment [see Warnings and Precautions (5.7)].
Some studies with human insulin have shown increased circulating levels of insulin in patients with renal failure.
In patients with mild and moderate renal impairment no dose adjustment is required but close monitoring for lixisenatide related adverse reactions and for changes in renal function is recommended because of higher incidences of hypoglycemia, nausea and vomiting that were observed in these patients. Increased gastrointestinal adverse reactions may lead to dehydration and acute renal failure and worsening of chronic failure in these patients.
Clinical experience in patients with severe renal impairment is limited as there were only 5 patients with severe renal impairment (eGFR 15 to less than 30 mL/min/1.73 m2) exposed to lixisenatide in all controlled studies. Lixisenatide exposure was higher in these patients [see Clinical Pharmacology (12.3)]. Patients with severe renal impairment exposed to lixisenatide should be closely monitored for occurrence of gastrointestinal adverse reactions and for changes in renal function.
There is no therapeutic experience in patients with end-stage renal disease (eGFR <15 mL/min/1.73 m2), and it is not recommended to use Soliqua 100/33 in this population.
The effect of hepatic impairment on the pharmacokinetics of Soliqua 100/33 has not been studied. Frequent glucose monitoring and dose adjustment may be necessary for Soliqua 100/33 in patients with hepatic impairment [see Warnings and Precautions (5.6)].
Patients with Gastroparesis
Lixisenatide, one of the components of Soliqua 100/33, slows gastric emptying. Patients with preexisting gastroparesis were excluded from clinical trials of Soliqua 100/33. Soliqua 100/33 is not recommended in patients with severe gastroparesis.
Excess insulin administration may cause hypoglycemia and hypokalemia [see Warnings and Precautions (5.6, 5.9)]. Mild episodes of hypoglycemia can usually be treated with oral carbohydrates. Adjustments in drug dosage, meal patterns, or exercise may be needed.
More severe episodes of hypoglycemia with coma, seizure, or neurologic impairment may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose. After apparent clinical recovery from hypoglycemia, continued observation and additional carbohydrate intake may be necessary to avoid recurrence of hypoglycemia. Hypokalemia must be corrected appropriately.
During clinical studies, doses up to 30 mcg of lixisenatide twice daily (3 times the daily recommended dose) were administered to type 2 diabetic patients in a 13-week study. An increased incidence of gastrointestinal disorders was observed.
In case of overdose, appropriate supportive treatment should be initiated according to the patient's clinical signs and symptoms and the Soliqua 100/33 dose should be reduced to the prescribed dose.
Soliqua 100/33 Description
Soliqua 100/33 (insulin glargine and lixisenatide injection), for subcutaneous use, is a combination of a long-acting basal insulin analog, insulin glargine, and a GLP-1 receptor agonist, lixisenatide.
Each Soliqua 100/33 prefilled single-patient-use disposable pen contains 300 units of insulin glargine and 100 mcg of lixisenatide in 3 mL of a clear, colorless to almost colorless, sterile, and aqueous solution. Each mL of solution contains 100 units insulin glargine and 33 mcg lixisenatide.
Soliqua 100/33 contains the following inactive ingredients (per mL): 3 mg of methionine, 2.7 mg of metacresol, 20 mg of glycerol, 30 mcg of zinc, hydrochloric acid, sodium hydroxide and water for injection.
Insulin glargine is a human insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12) as the production organism. Insulin glargine differs from human insulin in that the amino acid asparagine at position A21 is replaced by glycine and two arginines are added at the C-terminus of the B-chain. Insulin glargine has low aqueous solubility at neutral pH. At pH 4 insulin glargine is completely soluble. Chemically, insulin glargine is 21A-Gly-30Ba-L-Arg-30Bb-L-Arg-human insulin and has the empirical formula C267H404N72O78S6 and a molecular weight of 6063. Insulin glargine has the following structural formula:
Lixisenatide is a synthetic analogue of human GLP-1 which acts as a GLP-1 receptor agonist. Lixisenatide is a peptide containing 44 amino acids, which is amidated at the C-terminal amino acid (position 44). The order of the amino acids is given in the figure below. Its molecular weight is 4858.5, and the empirical formula is C215H347N61O65S with the following chemical structure:
Soliqua 100/33 - Clinical Pharmacology
Mechanism of Action
Soliqua 100/33 is a combination of insulin glargine, a basal insulin analog, and lixisenatide, a GLP-1 receptor agonist.
The primary activity of insulin, including insulin glargine, is regulation of glucose metabolism. Insulin and its analogs lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis and proteolysis, and enhances protein synthesis.
Lixisenatide is a GLP-1 receptor agonist that increases glucose-dependent insulin release, decreases glucagon secretion, and slows gastric emptying.
The combination of insulin glargine and lixisenatide has no impact on the pharmacodynamics of insulin glargine. The impact of the combination of insulin glargine and lixisenatide on the pharmacodynamics of lixisenatide has not been studied in phase 1 studies.
In a clinical pharmacology study in adults with type 2 diabetes mellitus, lixisenatide reduced fasting plasma glucose and postprandial blood glucose AUC0–300min compared to placebo (-33.8 mg/dL and -387 mg∙h/dL, respectively) following a standardized test meal. The effect on postprandial blood glucose AUC was most notable with the first meal, and the effect was attenuated with later meals in the day.
Treatment with lixisenatide 20 mcg once daily reduced postprandial glucagon levels (AUC0–300min) compared to placebo by -15.6 h∙pmol/L after a standardized test meal in patients with type 2 diabetes.
Cardiac electrophysiology (QTc)
At a dose 1.5-times the recommended dose, lixisenatide does not prolong the QTc interval to any clinically relevant extent.
The insulin glargine/lixisenatide ratio has no relevant impact on the PK of insulin glargine in Soliqua 100/33.
Compared to administration of lixisenatide alone, the Cmax is lower whereas the AUC is generally comparable when administered as Soliqua 100/33. The insulin glargine/lixisenatide ratio has no impact on the PK of lixisenatide in Soliqua 100/33. The observed differences in the PK of lixisenatide when given as Soliqua 100/33 or alone are not considered to be clinically relevant.
After subcutaneous administration of insulin glargine/lixisenatide combinations, insulin glargine showed no pronounced peak. Exposure to insulin glargine ranged from 86% to 101% compared to administration of insulin glargine alone.
After subcutaneous administration of insulin glargine/lixisenatide combinations, the median tmax of lixisenatide was in the range of 2.5 to 3.0 hours. There was a small decrease in Cmax of lixisenatide of 22%–34% compared with separate simultaneous administration of insulin glargine and lixisenatide, which is not likely to be clinically significant. There are no clinically relevant differences in the rate of absorption when lixisenatide is administered subcutaneously in the abdomen, thigh, or arm.
The protein binding of lixisenatide is 55%.
Metabolism and elimination
A metabolism study in humans who received insulin glargine alone indicates that insulin glargine is partly metabolized at the carboxyl terminus of the B chain in the subcutaneous depot to form two active metabolites with in vitro activity similar to that of human insulin, M1 (21A-Gly-insulin) and M2 (21A-Gly-des-30B-Thr-insulin). Unchanged drug and these degradation products are also present in the circulation.
Lixisenatide is presumed to be eliminated through glomerular filtration, and proteolytic degradation.
After multiple dose administration in patients with type 2 diabetes, mean terminal half-life was approximately 3 hours and the mean apparent clearance (CL/F) about 35 L/h.
Effects of age, body weight, gender and race
Insulin glargine: Effect of age, race, and gender on the pharmacokinetics of insulin glargine has not been evaluated. In controlled clinical trials in adults with insulin glargine (100 units/mL), subgroup analyses based on age, race, and gender did not show differences in safety and efficacy.
Lixisenatide: Age, body weight, gender, and race were not observed to meaningfully affect the pharmacokinetics of lixisenatide in population PK analyses.
Lixisenatide: Compared to healthy subjects (N=4), plasma Cmax of lixisenatide was increased by approximately 60%, 42%, and 83% in subjects with mild (CLcr 60–89 mL/min [N=9]), moderate (CLcr 30–59 mL/min [N=11]), and severe (CLcr 15–29 mL/min [N=8]) renal impairment. Plasma AUC was increased by approximately 34%, 69% and 124% with mild, moderate, and severe renal impairment, respectively [see Use in Specific Populations (8.6)].
Drug interaction studies with Soliqua 100/33
Due to their peptidic nature, insulin glargine and lixisenatide have no relevant potential to induce or inhibit CYP isozymes and, therefore, no direct drug interaction is expected.
Beyond the interaction studies performed with the individual components no additional interaction studies were conducted with Soliqua 100/33.
Drug interaction studies with lixisenatide
The drug interaction studies focused on the potential for lixisenatide to influence the rate and extent of exposure to coadministered drugs due to its known delaying effect on gastric emptying.
Lixisenatide 10 mcg did not change the overall exposure (AUC) of acetaminophen following administration of a single dose of acetaminophen 1000 mg, whether before or after lixisenatide. No effects on acetaminophen Cmax and tmax were observed when acetaminophen was administered 1 hour before lixisenatide. When administered 1 or 4 hours after 10 mcg lixisenatide, Cmax of acetaminophen was decreased by 29% and 31%, respectively, and median tmax was delayed by 2.0 and 1.75 hours, respectively.
Administration of a single dose of an oral contraceptive medicinal product (ethinylestradiol 0.03 mg/levonorgestrel 0.15 mg) 1 hour before or 11 hours after 10 mcg lixisenatide, did not change Cmax, AUC, t1/2 and tmax of ethinylestradiol and levonorgestrel.
Administration of the oral contraceptive 1 hour or 4 hours after lixisenatide did not affect the overall exposure (AUC) and mean terminal half-life (t1/2) of ethinylestradiol and levonorgestrel. However, Cmax of ethinylestradiol was decreased by 52% and 39%, respectively, and Cmax of levonorgestrel was decreased by 46% and 20%, respectively, and median tmax was delayed by 1 to 3 hours.
When lixisenatide 20 mcg and atorvastatin 40 mg were coadministered in the morning for 6 days, the exposure of atorvastatin was not affected, while Cmax was decreased by 31% and tmax was delayed by 3.25 hours. No such increase for tmax was observed when atorvastatin was administered in the evening and lixisenatide in the morning but the AUC and Cmax of atorvastatin were increased by 27% and 66%, respectively.
Warfarin and other coumarin derivatives
After concomitant administration of warfarin 25 mg with repeated dosing of lixisenatide 20 mcg, there were no effects on AUC or INR (International Normalized Ratio) while Cmax was reduced by 19% and tmax was delayed by 7 hours.
After concomitant administration of lixisenatide 20 mcg and digoxin 0.25 mg at steady state, the AUC of digoxin was not affected. The tmax of digoxin was delayed by 1.5 hour and the Cmax was reduced by 26%.
After concomitant administration of lixisenatide 20 mcg and ramipril 5 mg during 6 days, the AUC of ramipril was increased by 21% while the Cmax was decreased by 63%. The AUC and Cmax of the active metabolite (ramiprilat) were not affected. The tmax of ramipril and ramiprilat were delayed by approximately 2.5 hours.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No animal studies have been conducted with the combination of insulin glargine and lixisenatide to evaluate carcinogenesis, mutagenesis, or impairment of fertility.
In mice and rats, standard two-year carcinogenicity studies with insulin glargine were performed at doses up to 0.455 mg/kg, which was for the rat approximately 2-times and for the mouse approximately 1-times the recommended human subcutaneous high dose of 60 units/day (0.0364 mg/kg/day), based on mg/m2. The findings in female mice were not conclusive due to excessive mortality in all dose groups during the study. Histiocytomas were found at injection sites in male rats (statistically significant) and male mice (not statistically significant) in acid vehicle containing groups. These tumors were not found in female animals, in saline control, or insulin comparator groups using a different vehicle. The relevance of these findings to humans is unknown.
Insulin glargine was not mutagenic in tests for detection of gene mutations in bacteria and mammalian cells (Ames- and HGPRT-test) and in tests for detection of chromosomal aberrations (cytogenetics in vitro in V79 cells and in vivo in Chinese hamsters).
In a combined fertility and prenatal and postnatal study with insulin glargine in male and female rats at subcutaneous doses up to 0.36 mg/kg/day, which was approximately 2-times the recommended human subcutaneous maximum dose of 60 units/day (0.0364 mg/kg/day), based on mg/m2, maternal toxicity due to dose-dependent hypoglycemia, including some deaths, was observed. Consequently, a reduction of the rearing rate occurred in the high-dose group only.
Carcinogenicity studies of 2-years durations were conducted in CD-1 mice and Sprague-Dawley rats with twice daily subcutaneous doses of 40, 200, or 1000 mcg/kg. A statistically significant increase in thyroid C-cell adenomas was observed in males at 2,000 mcg/kg/day, resulting in exposures that are >180-times the human exposure achieved at 20 mcg/day based on plasma AUC.
Statistically significant increases in thyroid C-cell adenomas were seen at all doses in rats, resulting in systemic exposures that are ≥15-times the human exposure achieved at 20 mcg/day based on plasma AUC. A numerical increase in thyroid C-cell carcinomas was observed in rats at ≥400 mcg/kg/day, resulting in systemic exposures that are ≥56-times the human exposure achieved at 20 mcg/day based on plasma AUC.
Lixisenatide was not mutagenic or clastogenic in a standard battery of genotoxicity tests (bacterial mutagenicity [Ames], human lymphocyte chromosome aberration, mouse bone marrow micronucleus).
Impairment of fertility
Studies in which male and female rats received twice daily subcutaneous doses lixisenatide of 2, 29, or 414 mcg/kg prior to pairing through gestation day 6 did not indicate any adverse effects on male or female fertility in rats up to the highest dose tested, 414 mcg/kg, or approximately 400-times the clinical systemic exposure at 20 mcg/day based on mcg/m2.
Overview of Clinical Studies
Soliqua 100/33 was evaluated in two randomized clinical studies in patients with type 2 diabetes mellitus. In each of the active-controlled trials, treatment with Soliqua 100/33 produced statistically significant improvements in HbA1c.
Clinical Study in Patients with Type 2 Diabetes Uncontrolled on OAD Treatment
A total of 1170 patients with type 2 diabetes were randomized in an open-label, 30-week, active-controlled study (Study A: NCT05058147) to evaluate the efficacy and safety of Soliqua 100/33 compared to the individual components, insulin glargine 100 units/mL and lixisenatide.
Patients with type 2 diabetes, treated with metformin alone or treated with metformin and a second OAD treatment that could be a sulfonylurea or a glinide or a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or a dipeptidyl peptidase-4 (DPP-4) inhibitor, and who were not adequately controlled with this treatment (HbA1c range 7.5% to 10% for patients previously treated with metformin alone and 7% to 9% for patients previously treated with metformin and a second OAD treatment) entered a run-in period for 4 weeks. During this run-in period, metformin treatment was optimized and all other OADs were discontinued. At the end of the run-in period, patients who remained inadequately controlled (HbA1c between 7% and 10%) were randomized to either Soliqua 100/33 (n=469), insulin glargine 100 units/mL (n=467), or lixisenatide (n=234).
The type 2 diabetes population had the following characteristics: mean age was 58.4 years, 50.6% were male, 90.1% were Caucasian, 6.7% were Black or African American, and 19.1% were Hispanic. At screening, the mean duration of diabetes was approximately 9 years, the mean BMI was approximately 31.7 kg/m2, and mean eGFR was 84.8 mL/min/1.73 m2.
Soliqua 100/33 and insulin glargine were to be titrated weekly to target a fasting plasma glucose goal of <100 mg/dL. Patients could not increase their dose by more than 4 units per week and the prespecified maximum dose of insulin glargine was limited to 60 units. The targeted fasting plasma glucose goal was achieved in 35% of patients in both groups at 30 weeks.
At Week 30, Soliqua 100/33 provided statistically significant improvement in HbA1c (p-value <0.0001) compared to insulin glargine 100 units/mL and lixisenatide-treated patients (-1.6%, -1.3%, and -0.9%). In a prespecified analysis of this primary endpoint, the differences observed were consistent with regard to baseline OAD use (metformin alone or metformin plus second OAD).
The mean difference (95% CI) in HbA1c reduction between Soliqua 100/33 and insulin glargine was -0.3% (-0.4, -0.2) and -0.7% (-0.8, -0.6) compared to lixisenatide.
See Table 5 for the other endpoints in the study. The difference in the glucose lowering effect observed in the trial may not necessarily reflect the effect that will be observed in the care setting where insulin glargine dosage can be different than that used in the trial.

Clinical Studies in Patients with Type 2 Diabetes Uncontrolled on Basal Insulin
A total of 736 patients with type 2 diabetes participated in a randomized, 30-week, active-controlled, open-label, 2-treatment arm, parallel-group, multicenter study (Study B: NCT02058160) to evaluate the efficacy and safety of Soliqua 100/33 compared to insulin glargine 100 units/mL.
Patients screened had type 2 diabetes were treated with basal insulin for at least 6 months, receiving a stable daily dose of between 15 and 40 units alone or combined with 1 or 2 OADs (metformin, sulfonylurea, glinide, SGLT-2 inhibitor or a DPP-4 inhibitor), had an HbA1c between 7.5% and 10% and a FPG less than or equal to 180 mg/dL or 200 mg/dL depending on their previous antidiabetic treatment.
This type 2 diabetes population had the following characteristics: Mean age was 60 years, 46.7% were male, 91.7% were Caucasian, 5.2% were Black or African American and 17.9% were Hispanic. At screening, the mean duration of diabetes was approximately 12 years, the mean BMI was approximately 31 kg/m2, mean eGFR was 80.6 mL/min/1.73 m2 and 86.1% of patients had an eGFR ≥60 mL/min.
After screening, eligible patients (n=1018) entered a 6-week run-in phase where patients remained on or were switched to insulin glargine 100 units/mL, if they were treated with another basal insulin, and had their insulin glargine dose titrated/stabilized while continuing metformin (if previously taken). The mean HbA1c decreased during run-in period from 8.5% to 8.1%. Any other OADs were discontinued.
At the end of the run-in period, patients with an HbA1c between 7% and 10%, FPG ≤140 mg/dL and insulin glargine daily dose of 20 to 50 units (mean of 35 units), were randomized to either Soliqua 100/33 (n=367) or insulin glargine 100 units/mL (n=369).
Soliqua 100/33 and insulin glargine were to be titrated weekly to target a fasting plasma glucose goal of <100 mg/dL. The mean dose of insulin glargine at baseline was 35 units. The maximum dose of insulin glargine allowed in the trial was 60 units (insulin dose cap) in both groups. The targeted fasting plasma glucose goal was achieved in 33% of patients in both groups at 30 weeks.
At Week 30, there was a reduction in HbA1c from baseline of -1.1% for Soliqua 100/33 and -0.6% for insulin glargine 100 units/mL. The mean difference (95% CI) in HbA1c reduction between Soliqua 100/33 and insulin glargine was -0.5 [-0.6, -0.4] and statistically significant. The trial was designed to show the contribution of the GLP-1 component to glycemic lowering and the insulin glargine dose and the dosing algorithm was selected to isolate the effect of the GLP-1 component. At the end of the trial, the doses of insulin glargine were equivalent between treatment groups. The mean final dose of Soliqua 100/33 and insulin glargine at week 30 was 46.7 units (for Soliqua 100/33: 46.7 units insulin glargine/15.6 mcg lixisenatide). The difference in effect observed in the trial may not necessarily reflect the effect that will be observed in the care setting where alternative insulin glargine dosage can be used. See Table 6 for the other endpoints in the study.

How Supplied/Storage and Handling
Soliqua 100/33 is an injection supplied as a sterile, clear, colorless to almost colorless solution in a 3 mL prefilled, disposable, single-patient-use pen injector:
|Dosage Unit/Strength||Package size||NDC #|
|3 mL Soliqua 100/33 disposable prefilled pen
100 units/mL insulin glargine and 33 mcg/mL lixisenatide
|Package of 5||0024-5761-05|
Needles are not included. Only use needles that are compatible for use with Soliqua 100/33 prefilled pen.
Prior to first use, Soliqua 100/33 pen should be stored in a refrigerator, 36°F–46°F (2°C–8°C). Do not freeze. Protect from light. Discard after the expiration date printed on the label.
Soliqua 100/33 should not be stored in the freezer and should not be allowed to freeze. Discard Soliqua 100/33 if it has been frozen.
After first use, store at room temperature below 77°F (25°C). Replace the pen cap after each use to protect from light.
Discard pen 28 days after first use.
Always remove the needle after each injection and store the Soliqua 100/33 pen without a needle attached. This prevents contamination and/or infection, or leakage of the Soliqua 100/33 pen, and will ensure accurate dosing. Always use a new needle for each injection to prevent contamination.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide and Instructions for Use).
Inform patients that serious hypersensitivity reactions, including anaphylaxis, have been reported in clinical trials of Soliqua 100/33 and during postmarketing use of other GLP-1 receptor agonists. If symptoms of hypersensitivity reactions occur, instruct patients to stop taking Soliqua 100/33 and seek medical advice promptly [see Warnings and Precautions (5.1)].
Risk of Pancreatitis
Inform patients that persistent severe abdominal pain that may radiate to the back and which may or may not be accompanied by vomiting is the hallmark symptom of acute pancreatitis. Instruct patients to promptly discontinue Soliqua 100/33 and contact their physician if persistent severe abdominal pain occurs [see Warnings and Precautions (5.2)].
Never Share a Soliqua 100/33 Pen
Advise patients that they must never share a Soliqua 100/33 prefilled pen with another person, even if the needle is changed because doing so carries a risk for transmission of blood-borne pathogens.
Hyperglycemia or Hypoglycemia
Inform patients that hypoglycemia is the most common adverse reaction with insulin-containing products. Inform patients of the symptoms of hypoglycemia. Inform patients that the ability to concentrate and react may be impaired as a result of hypoglycemia. This may present a risk in situations where these abilities are especially important, such as driving or operating other machinery. Advise patients who have frequent hypoglycemia or reduced or absent warning signs of hypoglycemia to use caution when driving or operating machinery.
Advise patients that changes in Soliqua 100/33 regimen can predispose to hyperglycemia or hypoglycemia. Advise patients that changes in Soliqua 100/33 regimen should be made under close medical supervision [see Warnings and Precautions (5.4, 5.6)].
Dehydration and Renal Failure
Advise patients treated with Soliqua 100/33 of the potential risk of dehydration due to gastrointestinal adverse reactions and to take precautions to avoid fluid depletion. Inform patients of the potential risk for worsening renal function, which in some cases may require dialysis [see Warnings and Precautions (5.7)].
Overdose due to Medication Errors
Inform patients that Soliqua 100/33 contains two drugs: insulin glargine and lixisenatide. Accidental mix-ups between insulin products have been reported. To avoid medication errors between Soliqua 100/33 and other insulin products, instruct patients to always check the label before each injection. Advise patients that the administration of more than 60 units of Soliqua 100/33 daily can result in overdose of the lixisenatide component. Instruct patients not to administer concurrently with other glucagon-like peptide-1 receptor agonists.
Use in Pregnancy
Advise patients to inform their physicians if they are pregnant or intend to become pregnant [see Use in Specific Populations (8.1)].

INSTRUCTIONS FOR USE
SOLIQUA® 100/33 (So - lee - kwa)
(insulin glargine and lixisenatide injection) for subcutaneous use
Read these instructions carefully before using your Soliqua 100/33 pen.
Do not share your Soliqua 100/33 pen with other people, even if the needle has been changed. You may give other people a serious infection, or get a serious infection from them.
Soliqua 100/33 is an injectable prescription medicine that contains 2 diabetes medicines, insulin glargine and lixisenatide in a SoloStar pen. The drug combination in this pen is only for the daily injection of 15 to 60 units of Soliqua 100/33. Each unit dialed contains 1 unit insulin glargine and 0.33 mcg lixisenatide.
- Check the label on the Soliqua 100/33 pen each time you give your injection to make sure you are using the correct medicine.
- Do not use your pen if it is damaged or if you are not sure that it is working correctly.
- Perform a safety test before each injection (see "Step 3: Do a safety test").
- Always carry a spare pen and spare needles in case they are lost or stop working.
- Do not reuse needles. Always use a new sterile needle for each injection. This helps stop blocked needles, contamination, and infection. If you reuse needles, you might not get your dose (underdosing) or get too much (overdosing).
- Do not use Soliqua 100/33 in an insulin pump or inject Soliqua 100/33 into your vein (intravenously) or muscle (intramuscularly).
- Do not mix Soliqua 100/33 in any other type of insulin or liquid medicine prior to injection.
- Change (rotate) your injection sites within the area you chose with each dose. Do not use the same spot for each injection, to avoid skin thickening or pits at the injection site (lipodystrophy).
Learn to inject
- Talk with your healthcare provider about how to use the Soliqua 100/33 pen and how to inject correctly before using your pen.
- Ask for help if you have problems handling the pen, for example if you have vision problems.
- Read all of these instructions before using your pen. You may get too much or too little medicine if you do not follow the instructions correctly.
If you have any questions about your pen or about diabetes, ask your healthcare provider, go to www.soliqua100-33.com or call sanofi-aventis at 1-800-633-1610.
Supplies you will need:
- 1 Soliqua 100/33 pen
- 1 new sterile needle (see Step 2 "Attach a new needle")
- 1 alcohol swab
- a puncture-resistant container for used needles and pens (see "Throwing your pen away" at the end of this Instructions for Use)
Places to inject
Step 1: Check your pen
Take a new pen out of the refrigerator at least 1 hour before you inject. Cold medicine is more painful to inject.
- Check the name and expiration date on the label of your pen.
- Make sure you have the correct medicine. This pen is colored light green with an orange injection button (see the "Get to know your pen" diagram).
- Do not use your pen after the expiration date on the pen label.
- Pull off the pen cap.
- Check that the medicine is clear and colorless to almost colorless.
- If you see small particles, return it to your pharmacy for a replacement.
- Wipe the rubber seal with an alcohol swab.
If you have other injector pens
- Making sure you have the correct medicine is especially important if you have other injector pens.
- Do not reuse needles. Always use a new sterile needle for each injection. This helps stop blocked needles, contamination and infection.
- Only use needles that are meant to be used with Soliqua 100/33. Needles are supplied separately. If you do not know what needles to use, ask your healthcare provider or pharmacist.
- Take a new needle and peel off the protective seal.
- Keep the needle straight and screw it onto the pen until fixed. Do not over-tighten.
- Pull off the outer needle cap. Keep this for later.
- Pull off the inner needle cap and throw it away.
- Take care when handling needles to prevent needle-stick injury and cross-infection.
Perform a safety test before each injection to:
- Check your pen and the needle to make sure they are working properly.
- Make sure that you get the correct dose.
- Press the injection button all the way in.
- When the medicine comes out of the needle tip, your pen is working correctly.
If no liquid appears:
- You may need to repeat this step up to 3 times before seeing the medicine.
- If no medicine comes out after the third time, the needle may be blocked. If this happens:
- Do not use your pen if still no medicine comes out of the needle tip. Use a new pen.
- Do not use a syringe to remove medicine from your pen.
If you see air bubbles
- You may see air bubbles in the medicine. This is normal, they will not harm you.
Step 4: Select the dose
- Do not select a dose or press the injection button without a needle attached. This may damage your pen.
- Only use this pen to inject your daily dose from 15 to 60 units. Do not change your dose unless your healthcare provider has told you to change your dose.
- Do not use this pen if you need a single daily dose that is more than 60 units.
- Do not use the pen if your single daily dose is less than 15 units, the black area in dose window as shown in the picture.
- Make sure a needle is attached and the dose is set to '0'.
- Turn the dose selector until the dose pointer lines up with your dose.
- Do not dial your dose by counting the clicks, because you might dial the wrong dose. Always check the number in the dose window to make sure you dialed the correct dose.
- If you turn past your dose, you can turn back down.
- If there are not enough units left in your pen for your dose, the dose selector will stop at the number of units left.
- If you cannot select your full prescribed dose, use a new pen.
How to read the dose window
- Each line in the dose window equals 1 unit of Soliqua 100/33.
- Even numbers are shown in line with the dose pointer, as shown in picture.
30 units selected
- Odd numbers are shown as a line between even numbers, as shown in picture.
29 units selected
Units of medicine in your pen
- This pen contains 300 units of Soliqua 100/33 and it is intended to be used for more than one dose.
Step 5: Inject your dose
If you find it hard to press the injection button in, do not force it as this may break your pen. See the section after Step 5E below for help.
- Choose a place to inject as shown in the picture labeled "Places to inject."
- Push the needle into your skin as shown by your healthcare provider.
- Do not touch the injection button yet.
- Place your thumb on the injection button. Then press all the way in and hold.
- Do not press injection button at an angle. Your thumb could block the dose selector from turning.
- Keep the injection button held in and when you see "0" in the dose window, slowly count to 10.
- This will make sure you get your full dose.
- After holding and slowly counting to 10, release the injection button. Then remove the needle from your skin.
If you find it hard to press the injection button in:
- Change the needle (see Step 6 to remove the needle and Step 2 to attach a new needle) then do a safety test (see Step 3).
- If you still find it hard to press in, get a new pen.
- Do not use a syringe to remove medicine from your pen.
- Take care when handling needles to prevent needle-stick injury and cross-infection.
- Do not put the inner needle cap back on.
- Grip the widest part of the outer needle cap. Keep the needle straight and guide it into the outer needle cap back. Then push firmly on.
- The needle can puncture the cap if it is recapped at an angle.
- Grip and squeeze the widest part of the outer needle cap. Turn your pen several times with your other hand to remove the needle.
- Try again if the needle does not come off the first time.
- Throw away the used needle in a puncture-resistant container (see "Throwing your pen away" at the end of this Instructions for Use).
- Put your pen cap back on.
- Do not put the pen back in the refrigerator.
- Only use your pen for up to 28 days after its first use.
How to store your pen
Before first use
- Keep new pens in the refrigerator between 36°F to 46°F (2°C to 8°C).

- Do not put your pen back in the refrigerator.

How to care for your pen
Handle your pen with care
- Do not drop your pen or knock it against hard surfaces.
- If you think that your pen may be damaged, do not try to fix it. Use a new one.
Protect your pen from dust and dirt
- You can clean the outside of your pen by wiping it with a damp cloth (water only). Do not soak, wash or lubricate the pen. This may damage it.
- Put the used Soliqua 100/33 pen in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) the Soliqua 100/33 pen in your household trash.
- If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:
- made of a heavy-duty plastic,
- can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
- upright and stable during use,
- leak-resistant, and
- properly labeled to warn of hazardous waste inside the container.
- When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA's website at: http://www.fda.gov/safesharpsdisposal
