6. Adverse Reactions/Side Effects

The following clinically significant adverse reactions are described in greater details elsewhere in the labeling:

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates 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.

Prurigo Nodularis
A total of 508 adult subjects with prurigo nodularis were treated with NEMLUVIO in two placebo-controlled trials and an open label long-term extension trial. Of these, 375 subjects were exposed for at least 1 year in the drug development program for prurigo nodularis.

The safety of NEMLUVIO in adult subjects with prurigo nodularis was evaluated in two randomized, doubleblind, placebo-controlled, multicenter trials (OLYMPIA 1 and OLYMPIA 2). Subjects were treated for up to 24 weeks in OLYMPIA 1 and up to 16 weeks in OLYMPIA 2. In these 2 trials, 370 subjects were treated with subcutaneous injections of NEMLUVIO, and 186 subjects received placebo [see Clinical Studies (14.1)].

Subjects weighing less than 90 kg in the NEMLUVIO group received an initial NEMLUVIO dose of 60 mg or placebo at Week 0, followed by a NEMLUVIO dose of 30 mg or placebo every 4 weeks. Subjects weighing 90 kg or more in the NEMLUVIO group received an initial NEMLUVIO dose of 60 mg or placebo at Week 0 followed by a NEMLUVIO dose of 60 mg or placebo every 4 weeks.

During the treatment period in Trials OLYMPIA 1 and OLYMPIA 2, the proportion of subjects who discontinued treatment because of adverse reactions was 4% in the NEMLUVIO group versus 3% in the placebo group. Table 1 summarizes the adverse reactions that occurred at a rate of at least 1% in the NEMLUVIO group, and for which the rate exceeds the rate in the placebo group through Week 16.

Specific Adverse Reactions
Hypersensitivity reactions
Type 1 hypersensitivity reactions (Ig-E mediated reactions), including one report of discrete facial (peri-ocular) angioedema, were reported in subjects treated with NEMLUVIO [see Contraindications (4)].

Atopic Dermatitis
Adults and Pediatric Subjects 12 Years of Age and Older
A total of 1148 subjects, including 180 subjects 12 to 17 years of age, with moderate-to-severe atopic dermatitis were treated with NEMLUVIO for at least 1 year during the drug development program.

The safety of NEMLUVIO was evaluated in a pool of two randomized, double-blind, placebo-controlled, multicenter phase 3 trials (ARCADIA 1, ARCADIA 2). In these two trials, 1135 adult and pediatric subjects 12 years of age and older with moderate-to-severe AD were treated with subcutaneous injections of NEMLUVIO (initial dose of 60 mg, followed by 30 mg every 4 weeks), with concomitant topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) for up to 16 weeks (Initial Treatment Period) [see Clinical Studies (14.2)].

After the Initial Treatment Period, subjects who responded to NEMLUVIO were re-randomized to receive NEMLUVIO 30 mg every 4 weeks, NEMLUVIO 30 mg every 8 weeks, or placebo every 4 weeks for the Maintenance Treatment Period (Week 16 through Week 48) [see Clinical Studies (14.2)]. The safety population during the Maintenance Treatment Period had a mean age of 31 to 33 years (median age of 26 to 29 years) for the NEMLUVIO cohorts.

Week 0 to Week
16 In ARCADIA 1 and ARCADIA 2 trials through Week 16, the proportion of subjects who discontinued treatment because of adverse events was 2.3% in the NEMLUVIO every 4 weeks group and 2.2% in the placebo groups. Table 2 summarizes the adverse reactions that occurred at a rate of at least 1% in the NEMLUVIO group, and for which the rate exceeds the rate in the placebo group during the first 16 weeks of treatment.

Assessment of the safety profile of NEMLUVIO in 505 subjects up through Week 48 in the ARCADIA 1 and ARCADIA 2 trials was generally consistent with the safety profile observed at Week 16.

Specific Adverse Reactions

Hypersensitivity reactions
Type 1 hypersensitivity reactions (Ig-E mediated reactions) were reported in subjects treated with NEMLUVIO. This included occurrence of mild urticaria that did not lead to discontinuation of treatment.

Injection site reactions
The incidence of injection site reactions during the initial treatment period was reported for 1.2% of subjects treated with NEMLUVIO and 0.9% of subjects receiving placebo; during the maintenance period, the incidence was 0.6% with NEMLUVIO every 4 weeks, 0% with NEMLUVIO every 8 weeks, and 0% with placebo. None of these reactions led to discontinuation of treatment.

Herpes Zoster
During the initial treatment period, herpes zoster infections were reported in 5 subjects (0.4%) treated with NEMLUVIO (including 1 case of ophthalmic herpes zoster) and no subjects receiving placebo. Cases of herpes zoster were mild to moderate in severity and did not lead to discontinuation of treatment.

Pediatric Subjects 12 Years of Age and Older
The safety of NEMLUVIO was assessed in 176 subjects 12 to 17 years of age with moderate-to-severe atopic dermatitis enrolled in the ARCADIA 1 or ARCADIA 2 trials who received at least one dose of NEMLUVIO from Week 0 to Week 16 in the primary safety population. The safety profile of NEMLUVIO in these subjects through Week 16 was consistent with the safety profile observed in adults with atopic dermatitis.

The safety profile of NEMLUVIO in 98 subjects 12 to 17 years of age followed through Week 48 was consistent with the safety profile observed at Week 16.

8. Use In Specific Populations

8.1 Pregnancy

Risk Summary
Available data on NEMLUVIO use in pregnant women exposed during clinical trials are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In an enhanced pre- and postnatal development study in cynomolgus monkeys, when nemolizumab-ilto was administered subcutaneously during organogenesis to parturition, an increase in early postnatal death was observed at a dose 36 times the maximum recommended human dose (MRHD) for PN and 50 times for AD (see Data). The clinical significance of this nonclinical finding is unknown.

The background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations

Fetal/Neonatal Adverse Reactions

Transport of endogenous IgG antibodies across the placenta increases as pregnancy progresses, and peaks during the third trimester. Therefore, NEMLUVIO may be present in infants exposed in utero. The potential impact of infants being exposed in utero to NEMLUVIO should be considered.

Data

Animal Data

In an enhanced pre- and postnatal development study, subcutaneous doses up to 25 mg/kg of nemolizumab-ilto were administered to pregnant cynomolgus monkeys once every two weeks during organogenesis to parturition. No maternal or embryofetal toxicities were observed at doses up to 25 mg/kg (36 times the MRHD for PN and 50 times for AD, based on AUC comparison). Early postnatal death occurred in the offspring of one control monkey and 3 monkeys at 25 mg/kg (36 times the MRHD for PN and 50 times for AD, based on AUC comparison). The clinical significance of this nonclinical finding is unknown. Nemolizumab-ilto was administered subcutaneously to the offspring at doses up to 25 mg/kg (122 times the MRHD for PN and 168 times for AD, based on AUC comparison), once every 2 weeks for 6 months, starting from postnatal day 35. No adverse effects were noted in the remaining offspring.

8.2 Lactation

Risk Summary
There are no data on the presence of nemolizumab-ilto in human milk, the effects on the breastfed infant, or the effects on milk production. Nemolizumab-ilto was detected in breast milk of monkeys (see Data). Endogenous maternal IgG and monoclonal antibodies are transferred in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to nemolizumab-ilto are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NEMLUVIO and any potential adverse effects on the breastfed child from NEMLUVIO or from the underlying maternal condition.

Data
Nemolizumab-ilto was detected in breast milk of monkeys in the enhanced pre- and postnatal development study following subcutaneous doses up to 25 mg/kg once every two weeks during organogenesis to parturition. The mean nemolizumab-ilto concentrations in milk were approximately 0.3 – 0.5% of the maternal plasma levels from lactation day 7 to 63. The concentration of nemolizumab-ilto in animal milk does not necessarily predict the concentration of drug in human milk.

8.4 Pediatric Use

Prurigo Nodularis
The safety and effectiveness of NEMLUVIO have not been established in pediatric patients.

Atopic Dermatitis
The safety and effectiveness of NEMLUVIO for the treatment of moderate-to-severe atopic dermatitis in combination with topical corticosteroids and/or calcineurin inhibitors have been established in pediatric patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies. Use of NEMLUVIO for this indication is supported by evidence from two randomized, double-blind, placebo-controlled trials [See Adverse Reactions (6.1) and Clinical Studies (14.2)].

The safety and effectiveness of NEMLUVIO have not been established in pediatric patients younger than 12 years of age.

8.5 Geriatric Use

Prurigo Nodularis
Of the 370 subjects with prurigo nodularis exposed to NEMLUVIO in OLYMPIA 1 and OLYMPIA 2, 99 (26.8%) subjects were 65 years of age or older. The long-term safety of NEMLUVIO was assessed in 508 subjects, among which 133 (26.2%) were 65 years of age or older. Clinical trials of NEMLUVIO did not include sufficient numbers of subjects 65 years of age or older to determine whether they respond differently than younger adult subjects. [see Clinical Pharmacology (12.3)].

Atopic Dermatitis
Of the 1192 subjects with atopic dermatitis exposed to NEMLUVIO in the primary safety population, 72 (6.0%) subjects were 65 years of age or older. The long-term safety of NEMLUVIO was assessed in 78 (4.5%) subjects 65 years of age or older. Clinical studies of NEMLUVIO did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger adult subjects [see Clinical Pharmacology (12.3)].

10. Overdosage

There is no specific treatment for NEMLUVIO overdosage. In the event of overdosage, contact Poison Control (1-800-222-1222) for the latest recommendations and monitor the patient for any signs or symptoms of adverse reactions and institute appropriate symptomatic treatment immediately.

11. Nemluvio Description

Nemolizumab-ilto, an interleukin-31 receptor alpha (IL-31RA) antagonist, is a humanized monoclonal modified immunoglobulin G (IgG) antibody with a molecular weight of approximately 144 kDa. Nemolizumab-ilto is produced by recombinant DNA technology in Chinese Hamster Ovary cells.

NEMLUVIO (nemolizumab-ilto) for injection is a sterile, preservative-free, white lyophilized powder in a dualchamber, single-dose, prefilled pen for subcutaneous use. One chamber contains 30 mg of nemolizumab-ilto with inactive ingredients arginine hydrochloride (9.5 mg), poloxamer 188 (0.15 mg), sucrose (25.8 mg), trometamol (0.10 mg), and tris hydrochloride for pH adjustment. The diluent, water for injection, is in the other chamber. Following reconstitution, each prefilled pen delivers 30 mg/0.49 mL of nemolizumab-ilto with a pH of 6.7 to 7.3.

12. Nemluvio - Clinical Pharmacology

12.1 Mechanism of Action

Nemolizumab-ilto is a humanized IgG2 monoclonal antibody that inhibits IL-31 signaling by binding selectively to IL-31 RA. IL-31 is a naturally occurring cytokine that is involved in pruritus, inflammation, epidermal dysregulation, and fibrosis. Nemolizumab-ilto inhibited IL-31-induced responses including the release of proinflammatory cytokines and chemokines.

12.2 Pharmacodynamics

Pharmacodynamics of nemolizumab-ilto in the treatment of prurigo nodularis and atopic dermatitis are unknown.

12.3 Pharmacokinetics

After a single-dose, nemolizumab-ilto exposure increased dose proportionally over a dose range of 0.03 and 3 mg/kg following subcutaneous administration. After multiple doses, nemolizumab-ilto systemic exposure increased in an approximately dose-proportional manner across the subcutaneous dose range up to 30 mg. There was a decrease in bioavailability by 9% with the 60 mg subcutaneous dose and by 15% with the 90 mg subcutaneous dose.

  • Prurigo Nodularis: Following multiple doses of NEMLUVIO in subjects with prurigo nodularis, the estimated mean (SD) steady-state trough concentrations of nemolizumab-ilto were 3.04 (1.23) μg/mL in subjects with bodyweight less than 90 kg; and 3.66 (1.63) μg/mL in subjects with bodyweight of 90 kg or more. Steady state nemolizumab-ilto concentrations were achieved by week 4 in subjects weighting less than 90 kg and by week 12 in subjects weighing 90 kg or more.
  • Atopic Dermatitis: Following multiple doses of NEMLUVIO in subjects with atopic dermatitis, the estimated mean (SD) steady-state trough concentrations of nemolizumab-ilto were 2.63 (1.27) μg/mL for 30 mg administered every 4 weeks and 0.74 (0.44) μg/mL for 30 mg administered every 8 weeks. Steady-state nemolizumab-ilto concentrations were achieved 4 weeks after the initial 60 mg loading dose.

Absorption
Following an initial subcutaneous dose of 60 mg, nemolizumab-ilto reached peak mean (SD) concentrations (Cmax) of 7.5 (2.31) μg/mL by approximately 6 days post dose.

Distribution
The volume of distribution of nemolizumab-ilto was estimated to be 7.67 L.

Elimination
Nemolizumab-ilto is expected to be degraded in the same manner as endogenous IgG. The terminal elimination half-life (SD) of nemolizumab-ilto was estimated to be 18.9 (4.96) days and systemic clearance was estimated to be 0.263 L/day.

Metabolism
The metabolic pathway of nemolizumab-ilto has not been characterized. Nemolizumab-ilto is expected to be degraded into small peptides by catabolic pathways.

Specific Populations

Geriatric Populations

No clinically significant difference in the pharmacokinetics of nemolizumab-ilto was estimated based on age (subjects 18 to 65 years of age and older than 65 years of age). Dose adjustment in this population is not needed.

Pediatric Population

  • Atopic Dermatitis: No clinically significant difference in the pharmacokinetics of nemolizumab-ilto was estimated in pediatric subjects 12 to 17 years of age compared to adults. Dose adjustment in this population is not needed.

Renal or Hepatic Impairment
No clinically significant differences in the pharmacokinetics of nemolizumab-ilto were estimated based on mild to moderate renal or hepatic impairments. The effect of severe renal and severe hepatic impairments on the pharmacokinetics of nemolizumab-ilto is unknown.

Body Weight
The exposure of nemolizumab-ilto decreases with increasing body weight. After a 30-mg dose every 4 weeks, the steady state mean exposure parameters (AUCss, Cmaxss and Ctrough) of subjects with bodyweight of above 87 kg is expected to be 1.7-fold lower than that of subjects weighing below 62 kg.

  • Prurigo Nodularis: The variability in systemic exposure due to body weight had a clinically meaningful impact on skin lesion efficacy (IGA response) but not on pruritus improvement.
    Atopic Dermatitis: The difference in systemic exposure due to body weight had no clinically meaningful impact on efficacy in subjects with atopic dermatitis. Dose adjustment based on body weight is not needed.

Drug Interaction Studies
The effects of nemolizumab on the pharmacokinetics of midazolam (CYP3A4/5 substrate), warfarin (CYP2C9 substrate), omeprazole (CYP2C19 substrate), metoprolol (CYP2D6 substrate), and caffeine (CYP1A2 substrate) were evaluated in a study in 14 subjects with moderate to severe AD receiving an initial SC dose of 60 mg followed by 30 mg SC every four weeks for 12 weeks. No clinically significant changes in the exposure of CYP450 substrates before and after multiple nemolizumab injections were observed, with Cmax and AUC ratios ranging from 88.2 to 107.8%. The concomitant use of nemolizumab-ilto is unlikely to influence the PK profiles of CYP substrates.

12.6 Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of nemolizumab-ilto or other nemolizumab products.

Prurigo Nodularis:

  • In the Phase 3 trials (OLYMPIA 1, OLYMPIA 2) up to 24 weeks, the incidence of treatment-emergent ADAs was 7%; neutralizing antibodies were seen in 3% of subjects.

Atopic Dermatitis:

  • In the phase 3 trials (ARCADIA 1, ARCADIA 2) up to 16 weeks, the incidence of treatment-emergent ADAs was 6.1% (67/1092). Among subjects who continued treatment from week 16 through week 48 in the two studies, the ADA incidence was 13.9% (23/166) for those that received 30 mg every 4 weeks, and 10.6% (17/161) for those that received 30 mg every 8 weeks. Neutralizing antibody incidence was 4.5% (3/67) among the ADA+ subjects throughout 48 weeks in ARCADIA 1 and ARCADIA 2, respectively.

Anti-Drug Antibody Effects on Pharmacokinetics and Pharmacodynamics

  • Prurigo Nodularis: In the phase 3 trials in subjects with prurigo nodularis, there was no identified clinically significant effect of anti-drug antibodies on the pharmacokinetics, safety or efficacy of nemolizumab-ilto over the treatment duration of 24 weeks.

  • Atopic Dermatitis: In the phase 3 trials in subjects with atopic dermatitis, antibodies to nemolizumab-ilto were associated with reduced serum nemolizumab-ilto concentrations beyond Week 16. NEMLUVIO treated subjects who developed ADAs had nemolizumab-ilto concentrations that were 20% to 70% lower compared to subjects who did not develop ADAs. There was no clinically significant effect of anti-drug antibodies on safety or efficacy of nemolizumab-ilto over the treatment duration of 48 weeks.

13. Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Animal studies have not been conducted to evaluate the carcinogenic or mutagenic potential of NEMLUVIO.

No effects on fertility parameters as reproductive organ morphology, menstrual cycle length, or sperm/testicular analysis were observed in male or female sexually mature cynomolgus monkeys that were administered nemolizumab-ilto at subcutaneous doses up to 25 mg/kg once every two weeks for 6 months (53 times the MRHD for PN and 72 times for AD, based on AUC comparison). The monkeys were not mated to evaluate fertility.

14. Clinical Studies

14.1 Prurigo Nodularis

Two randomized, double-blind, placebo-controlled trials (OLYMPIA 1 [NCT04501666] and OLYMPIA 2 [NCT04501679]) enrolled a total of 560 adult subjects with prurigo nodularis (PN). Disease severity was defined using an Investigator’s Global Assessment (IGA) in the overall assessment of prurigo nodularis nodules on a severity scale of 0 to 4. Subjects enrolled in these two trials had an IGA score ≥ 3, severe pruritus as defined by a weekly average of the peak pruritus numeric rating scale (PP-NRS) score of ≥7 on a scale of 0 to 10, and greater than or equal to 20 nodular lesions. OLYMPIA 1 and OLYMPIA 2 assessed the effect of NEMLUVIO on the signs and symptoms of PN, targeting improvement in skin lesions and pruritus over 16 weeks. In OLYMPIA 1, subjects were extended up to 24 weeks of treatment.

Subjects weighing less than 90 kg in the NEMLUVIO group received subcutaneous injections of NEMLUVIO 60 mg at Week 0, followed by NEMLUVIO 30 mg injections every 4 weeks. Subjects weighing 90 kg or more in the NEMLUVIO group received subcutaneous injections of NEMLUVIO 60 mg at Week 0 and every 4 weeks.

In these trials, at baseline, 60% of subjects were female, 81% were White, 9% were Asian, 7% were Black or African American; for ethnicity, 4% of subjects identified as Hispanic or Latino. Twenty-five (25)% of subjects were older than 65 years of age. Thirty-two (32)% of subjects had a history of atopy. The baseline weekly average PP-NRS score was a mean of 8.5. Fifty-eight (58)% of subjects had a baseline IGA score of 3 (moderate PN), and 42% of subjects had a baseline IGA of 4 (severe PN).

The PP-NRS score is a weekly average of daily PP-NRS scores on an 11-point scale from 0-10 that assesses the maximal intensity of pruritus in the last 24 hours with 0 being no itch and 10 being worst itch imaginable. The IGA is a 5-category scale, including “0 = clear”, “1 = almost clear”, “2 = mild”, “3 = moderate” or “4 = severe” indicating the investigator’s overall assessment of the pruriginous nodules.

Efficacy was assessed with the proportion of subjects with an improvement of ≥4 from baseline in PP-NRS, the proportion of subjects with an IGA of 0 (Clear) or 1 (Almost Clear) and a ≥2-point improvement from baseline, the proportion of subjects who achieved a response in both PP-NRS and IGA per the criteria described above, and the proportion of subjects with PP-NRS <2.

The efficacy results for OLYMPIA 1 and OLYMPIA 2 are presented in Table 3 and Figures 1, 2, and 3.

14.2 Atopic Dermatitis

Two randomized, double-blind, placebo-controlled trials (ARCADIA 1 [NCT03985943] and ARCADIA 2 [NCT03989349]) enrolled a total of 1728 subjects 12 years of age and older with moderate-to-severe atopic dermatitis not adequately controlled by topical treatments. Disease severity was defined by an Investigator’s Global Assessment (IGA) score of 3 (moderate) and 4 (severe) in the overall assessment of atopic dermatitis, an Eczema Area and Severity Index (EASI) score of ≥16, a minimum body surface area (BSA) involvement of ≥10%, and a Peak Pruritus Numeric Rating Scale (PP-NRS) score of ≥ 4.

During the initial 16-week treatment period, subjects in the NEMLUVIO group received an initial subcutaneous injection of NEMLUVIO 60 mg (two 30 mg injections), followed by 30 mg injections every 4 weeks. Concomitant low and/or medium potency TCS and/or TCI were administered for at least 14 days prior to baseline and continued during the trial. Based on disease activity, these concomitant therapies could be tapered and/or discontinued at investigator discretion.

After 16 weeks, subjects achieving either EASI-75 or IGA success (i.e. NEMLUVIO responders) continued into the trial maintenance period for another 32 weeks to evaluate the maintenance of response achieved at Week 16. NEMLUVIO responders were re-randomized to receive either NEMLUVIO 30 mg every 4 weeks, NEMLUVIO 30 mg every 8 weeks, or placebo every 4 weeks (all groups continued background TCS/TCI). Subjects randomized to placebo in the initial treatment period who achieved the same clinical response at Week 16 continued to receive placebo every 4 weeks.

In these trials, at baseline, 51% of subjects were male, 80% were White, 13% were Asian, and 6% were Black or African American; for ethnicity, 9% of subjects identified as Hispanic or Latino. Fifteen (15)% of subjects were 12-17 years of age. Seventy (70)% of subjects had a baseline IGA score of 3 (moderate AD), and 30% of subjects had a baseline IGA score of 4 (severe AD). The baseline mean EASI score was 27.5 and the baseline mean weekly average PP-NRS was 7.1. Overall, 63% of subjects received other previous systemic treatments for AD.

The IGA is a 5-category scale, including “0 = clear”, “1 = almost clear”, “2 = mild”, “3 = moderate” or “4 = severe” indicating the investigator’s overall assessment of the AD. EASI scores range from 0 to 72 points and reflect the severity and extent of AD. EASI-75 indicates at least a 75% improvement in EASI score from baseline. The PP-NRS score is a weekly average of daily PP NRS scores on an 11-point scale from 0-10 that assesses the maximal intensity of pruritus in the last 24 hours with 0 being no itch and 10 being worst itch imaginable.

Both ARCADIA 1 and ARCADIA 2 assessed the co-primary endpoints of:

  • Proportion of subjects with an IGA success (defined as an IGA of 0 [clear] or 1 [almost clear] and a ≥2- point reduction from baseline) at Week 16
  • Proportion of subjects with EASI-75 (≥75% improvement in EASI from baseline) at Week 16

PP-NRS improvement ≥ 4 from baseline at Week 16 was a key secondary outcome in both trials.

Clinical Response at Week 16 (ARCADIA 1 and ARCADIA 2)
The efficacy results for ARCADIA 1 and ARCADIA 2 evaluating the initial treatment period with NEMLUVIO administered every 4 weeks over 16 weeks are presented in Table 4.

Maintenance and Durability of Response (Week 16 to Week 48)
The maintenance and durability of response in NEMLUVIO responders (IGA 0/1 or EASI-75 at Week 16) was evaluated between Week 16 and Week 48 in ARCADIA 1 and ARCADIA 2 trials. For the maintenance treatment period, NEMLUVIO responders were re-randomized to NEMLUVIO 30 mg every 4 weeks, NEMLUVIO 30 mg every 8 weeks or placebo every 4 weeks (NEMLUVIO withdrawal) with concomitant TCS/TCI. The results are presented in Table 5.

A. Preparing to inject NEMLUVIO

Step 1: Let NEMLUVIO reach room temperature
Injecting cold medicine might result in pain at the injection site.
Take the NEMLUVIO carton out of the refrigerator and let it come to room temperature for 30 to 45 minutes before starting Step 2 (see Figure A).

figure-a

Do not:

  • warm the pen with any heat source (such as microwave or direct sunlight). This might damage NEMLUVIO.
  • directly expose the pen to liquids.

Step 2: Wash your hands
a. Wash your hands with soap and water to avoid contamination and infection (see Figure B).
b. Dry hands completely.


figure-b



Step 3: Gather Supplies (see Figure C)
a. Remove the pen from the carton.
b. Gather the following supplies on a clean, flat and well-lit surface:

figure-c

  1. Pen
  2. Alcohol wipes*
  3. Sharps disposal container*
  4. Gauze pads or cotton balls*

*Items not included in the carton.

Note:
In some cases, your healthcare provider may prescribe 2 pens. Use 1 pen after the other.

Step 4: Check the NEMLUVIO pen for the following:
a. Expiration date has not passed.
b. The lyophilized powder is white and not dissolved (see Figure D).
c. The pen has not been dropped and is not damaged or cracked.

figure-d

Do not use the pen, unless all conditions above are met.
If any condition is not met, call: 1-866-735-4137.

Throw away (dispose of) the pen and use a new one (see Section C: Throwing away (Disposing of) NEMLUVIO).

Step 5: Activate the NEMLUVIO pen
Hold the pen upright and unlock the pen by turning the activation knob to the right until it stops (see Figure E).

This starts the process of transferring water to the powder chamber.

Only turn the activation knob to the right once.

figure-e



Step 6: Wait until the gray rod stops moving
Watch inspection window until gray rod has stopped moving (see Figure F).

figure-f
Do not shake the pen. Shaking the pen before the gray rod has completely stopped can affect the medicine dose.


Step 7: Dissolve the medicine
When the gray rod has completely stopped, hold the pen upright and shake the pen up and down for 30 seconds (see Figure G).

figure-g

Step 8: Wait 5 minutes for bubbles to decrease
Wait for bubbles to decrease and the lyophilized powder to dissolve completely. This will take about 5 minutes (see Figure H).

figure-h

Note: If the medicine has not dissolved completely, shake the pen up and down again for 30 seconds and then wait 5 minutes.
Note:
It is normal for a small foam layer or a few small air bubbles to remain in the dissolved medicine.

Step 9: Check the medicine in the inspection window
Check to see if the dissolved medicine:

  1. is clear and colorless to slightly yellow,
  2. does not contain particles (see Figure I).
    figure-i

Do not use the pen if the dissolved medicine is cloudy or contains any particles.

Throw away (dispose of) the pen and use a new one (see Section C: Throwing away (Disposing of) NEMLUVIO).

Note: After the medicine has dissolved, it must be used within 4 hours. During this time, it should be kept at room temperature (up to 77°F (25°C)). If you have not used it within 4 hours, throw it away (dispose of it).

B. Injecting NEMLUVIO

Step 10: Select one injection site (see Figure J)

Note: When using a second pen, select a different injection site at least 1 inch away from the first injection site.

Select the injection site using the following chart:

figure-j


Where not to inject:

  • near your waistline within about 2 inches around the navel.
  • into tender, bruised, red skin, or areas with scars or stretch marks.
  • twice into the same site (for example, within 1 inch).

Step 11: Clean the injection site (see Figure K)

a. Always use a new alcohol wipe to clean the injection site to avoid contamination and infection.
b. Let the skin air dry.

figure-k

Do not:

  • touch the injection site after cleaning.
  • fan, or blow air on the cleaned injection site.
  • reuse the alcohol wipe.

Step 12: Twist the gray cap

Do not:

  • pull the gray cap when twisting to avoid damaging the device.
  • touch the orange needle guard.
  1. Hold the pen upright (see Figure L, a)
  2. Gently twist the gray cap to the left (counterclockwise) until the orange needle guard pops up (see Figure L, b).
  3. Gently pull the gray cap off the orange needle guard (see Figure L, c). Do not press on the orange needle guard until ready to inject.
  4. After cap removal, please throw away (dispose of) the cap in a sharps disposal container (see Step 17).

Note: If the cap cannot be removed, refer back to Step 5 and make sure the activation knob is turned completely to the right until it stops.

figure-l

Step 13: Place the NEMLUVIO pen

Read Steps 13-16 before starting Step 13.

Note: Always inject the way your healthcare provider showed you.

Place the pen on the injection site vertically so that the orange needle guard is flat against the skin (see Figure M).

Note: Make sure you can easily see the inspection window during injection.

figure-m

Step 14: Start injection and hold the NEMLUVIO pen on the skin

Gently push the pen down until the orange needle guard is completely pushed in.

The injection starts right away with a click (see Figure N).

The orange rod will begin to move down the injection window.

Do not lift the pen yet and keep pushing down.

figure-n


Step 15: Inject for 15 seconds

Hold the pen in position and slowly count to 15 or use a timer or clock to count 15 seconds.

Check the inspection window to make sure the orange rod and gray rod have stopped moving (see Figure O).

This means the injection has been completed.

Note: It is normal that the orange rod does not cover the whole inspection window at the end of injection.


figure-o

Do not lift the pen until the orange rod and gray rod have stopped moving.

If the orange rod is not visible, please call: 1-866-735-4137. Throw away (dispose of) the pen and use a new one (see Section C for disposal details).


Step 16: Lift the NEMLUVIO pen up

a. Lift the pen straight up from your skin.
The orange needle guard automatically locks into place to cover the needle (see Figure P).

b. If there is bleeding, press a cotton ball or gauze over the injection site.

figure-p

Do not rub the injection site.


turn-over

C. Throwing away (disposing of) NEMLUVIO

Step 17: Throw away (dispose of) NEMLUVIO in a sharps disposal container

Avoid contact with the needle.

Throw away (dispose of) the used pen and the gray cap in an FDA cleared sharps disposal container right away after use (see Figure Q).

figure-q

Do not:

  • recap the pen after use,
  • dispose of the NEMLUVIO pen and cap in your household trash,
  • dispose of your used sharps disposal container in your household trash unless your community guidelines permit this,
  • recycle your used sharps disposal container.

If you do not have an 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 dispose of used pens.

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:

The needle is attached to the NEMLUVIO pen and covered by the gray cap.

When you twist the gray cap, the orange needle guard pops up and covers the needle until you inject the medicine.

For more information, please see the figures in Step 12 in this Instructions for Use.
Holding the NEMLUVIO pen with the gray cap upright helps prevent the medicine from leaking. It is normal to see a few drops of medicine inside the gray cap even when you hold the pen upright and remove the gray cap.
Dissolving the medicineHow do I know I injected myself the full dose of medicine in the pen?
How do I know if the medicine is fully dissolved?


To be sure you get the full dose of medicine, press and hold the NEMLUVIO pen against your skin.

You will feel the needle go into your skin. Hold the NEMLUVIO pen against your skin for 15 seconds. This will allow enough time for all the medicine to go from the pen to under your skin.

Only remove the NEMLUVIO pen when the orange rod and the gray rod have stopped moving.

After removing the NEMLUVIO pen, look for the orange rod in the window as a way to tell that the dose has been given. If the orange rod does not appear, contact 1-866-735-4137.

For details please refer to Step 15 in this Instructions for Use.
To dissolve, shake the NEMLUVIO pen in an upright position, up and down, until the white particles are no longer on the bottom, top, or sides. The dissolved medicine should look clear. Please refer to Step 9 in this Instructions for Use.

After shaking the NEMLUVIO pen, look through both sides of the inspection window. You should not see any white particles along the bottom, top, or sides.

It is acceptable to have small air bubbles or a small foam layer on top of the medicine. It does not harm you.

If you see white particles in the medicine, the medicine powder is not fully dissolved.
