6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

…

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, double- blind, 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.

Table 1: Adverse Reactions Occurring in greater than or equal to 1% of Adult Subjects with Prurigo Nodularis in the NEMLUVIO Group and Greater than in the Placebo Group in the OLYMPIA 1 and OLYMPIA 2 Trials 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.

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underline:

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 wasadministered 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.

Prurigo Nodularis

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

8.5 Geriatric Use

Additions and/or revisions underlined:

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)].
