Psoriatic Arthritis Clinical Trials OTEZLA was evaluated in three multicenter, randomized, double-blind, placebo-controlled trials (PsA-1, PsA-2, and PsA-3) of similar design in adult subjects with active psoriatic arthritis [see Clinical Studies (14.1) ] . Across the three trials, there were 1493 subjects randomized equally to placebo, OTEZLA 20 mg twice daily or OTEZLA 30 mg twice daily. Titration was used over the first 5 days [see Dosage and Administration (2.1) ] . Placebo subjects whose tender and swollen joint counts had not improved by at least 20% were re-randomized 1:1 in a blinded fashion to either OTEZLA 20 mg twice daily or 30 mg twice daily at week 16 while OTEZLA subjects remained on their initial treatment. Subjects ranged in age from 18 to 83 years, with an overall median age of 51 years. The majority of the most common adverse reactions presented in Table 3 occurred within the first 2 weeks of treatment and tended to resolve over time with continued dosing. Diarrhea, headache, and nausea were the most commonly reported adverse reactions. The most common adverse reactions leading to discontinuation for subjects taking OTEZLA were nausea (1.8%), diarrhea (1.8%), and headache (1.2%). The proportion of subjects with psoriatic arthritis who discontinued treatment due to any adverse reaction was 4.6% for subjects taking OTEZLA 30 mg twice daily and 1.2% for placebo-treated subjects. Table 3. Adverse Reactions Reported in ≥ 2% of Adult Subjects with Active Psoriatic Arthritis on OTEZLA 30 mg Twice Daily and ≥ 1% than That Observed in Subjects on Placebo up to Day 112 (Week 16) Placebo OTEZLA 30 mg BID BID = twice daily.

Subjects were randomized to receive OTEZLA 30 mg twice daily or placebo twice daily. Titration was used over the first 5 days [see Dosage and Administration (2.1) ] . Subjects ranged in age from 18 to 83 years, with an overall median age of 46 years. Diarrhea, nausea, and upper respiratory tract infection were the most commonly reported adverse reactions (see Table 4 ). The most common adverse reactions leading to discontinuation for subjects taking OTEZLA were nausea (1.6%), diarrhea (1.0%), and headache (0.8%). The proportion of subjects with plaque psoriasis who discontinued treatment due to any adverse reaction was 6.1% for subjects treated with OTEZLA 30 mg twice daily and 4.1% for placebo-treated subjects.

OTEZLA was evaluated in a Phase 3, multicenter, randomized, placebo-controlled trial (PSOR-3) in adults with moderate to severe plaque psoriasis of the scalp [see Clinical Studies (14.2) ] . A total of 302 subjects were randomized to receive OTEZLA 30 mg twice daily or placebo twice daily. The most commonly reported adverse reactions that occurred at a higher rate in the OTEZLA group than in the placebo group were: diarrhea (31% vs. 11%), nausea (22% vs. 6%), headache (12% vs. 5%), and vomiting (6% vs. 2%). The proportion of subjects who discontinued treatment because of any adverse reaction during the 16-week placebo-controlled period of the trial was 6% for subjects who received OTEZLA 30 mg twice daily and 3% for subjects who received placebo. Gastrointestinal adverse reactions that led to discontinuation of treatment were diarrhea (3% vs. 0%), nausea (1.5% vs. 1%), and vomiting (1.5% vs. 0%) in the OTEZLA group compared to placebo. OTEZLA was evaluated in a Phase 3, multicenter, randomized, placebo-controlled trial (PSOR-5) in adults with moderate to severe plaque psoriasis of the genital area [see Clinical Studies (14.2) ] . A total of 289 subjects were randomized to receive OTEZLA 30 mg twice daily or placebo twice daily. Overall, the safety profile observed in the OTEZLA group during the placebo-controlled phase was consistent with the safety profile previously established in adult subjects with moderate to severe plaque psoriasis. Adverse Reactions from Clinical Trials in Pediatric Subjects 6 to 17 Years of Age OTEZLA was evaluated in a Phase 3, multicenter, randomized, placebo-controlled trial (PSOR-6) in pediatric subjects 6 to 17 years of age with moderate to severe plaque psoriasis [see Clinical Studies (14.3) ] . A total of 245 subjects were randomized to receive OTEZLA (163 subjects, at a dosage of 20 mg twice daily or 30 mg twice daily, based on body weight) or placebo (82 subjects) twice daily during the 16-week placebo-controlled phase of the trial. The trial also included a 36-week extension phase during which all subjects received OTEZLA 20 mg or 30 mg twice daily. Overall, the safety profile observed in pediatric subjects treated with OTEZLA during the study was consistent with the safety profile established in adult subjects with moderate to severe plaque psoriasis. Mild to Moderate Plaque Psoriasis Clinical Trial in Adults OTEZLA was evaluated in a Phase 3, multicenter, randomized, placebo-controlled trial (PSOR-4) in adult subjects with mild to moderate plaque psoriasis [see Clinical Studies (14.4) ] . A total of 595 subjects were randomized to receive OTEZLA 30 mg twice daily (297 subjects) or placebo twice daily (298 subjects) during the placebo-controlled phase of the trial. The trial also included an open label extension phase during which all subjects received OTEZLA 30 mg twice daily. Overall, the safety profile observed in the OTEZLA group during the placebo-controlled phase was consistent with the safety profile previously established in adult subjects with moderate to severe plaque psoriasis. Behçet's Disease Clinical Trials OTEZLA was evaluated in a Phase 3, multicenter, randomized, placebo-controlled trial (BCT-002) in adult subjects with Behçet's Disease (BD) with active oral ulcers [see Clinical Studies (14.5) ] . A total of 207 subjects were randomized to receive OTEZLA 30 mg twice daily or placebo twice daily. Titration was used over the first 5 days [see Dosage and Administration (2.1) ] . After Week 12, all subjects received treatment with OTEZLA 30 mg twice daily. Subjects ranged in age from 19 to 72, with a mean age of 40 years. Diarrhea, nausea, headache, and upper respiratory tract infection were the most commonly reported adverse reactions (see Table 5 ). The proportion of subjects with BD who discontinued treatment due to any adverse reaction during the placebo-controlled period of the trial, was 2.9% for subjects treated with OTEZLA 30 mg twice daily and 4.9% for placebo-treated subjects. Table 5.
