Known hypersensitivity to apremilast or to any of the excipients in the formulation ( 4 )

6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: Hypersensitivity [see Warnings and Precautions (5.1) ] Diarrhea, Nausea, and Vomiting [see Warnings and Precautions (5.2) ] Depression [see Warnings and Precautions (5.3) ] Weight Decrease [see Warnings and Precautions (5.4) ] Drug Interactions [see Warnings and Precautions (5.5) ] Psoriatic Arthritis : The most common adverse reactions (≥ 5%) are diarrhea, nausea, and headache ( 6.1 ) Plaque Psoriasis : The most common adverse reactions (≥ 5%) are diarrhea, nausea, upper respiratory tract infection, and headache, including tension headache ( 6.1 ) Behçet's Disease : The most common adverse reactions (≥ 10%) are diarrhea, nausea, headache, and upper respiratory tract infection ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amgen Inc. at 1-800-77-AMGEN (1-800-772-6436) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 clinical practice. 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.

7 DRUG INTERACTIONS 7.1 Strong CYP450 Inducers Co-administration with strong CYP450 inducers (such as rifampin) decreases apremilast exposure and may result in loss of efficacy of OTEZLA/OTEZLA XR [see Warnings and Precautions (5.5) and Clinical Pharmacology (12.3) ] .

8 USE IN SPECIFIC POPULATIONS Severe Renal Impairment : Increased systemic exposure of OTEZLA has been observed. For adults and for pediatric patients weighing 50 kg or more, reduce dosage to OTEZLA 30 mg once daily. For pediatric patients weighing 20 kg to less than 50 kg, reduce dosage to OTEZLA 20 mg once daily ( 2.3 , 8.6 ). 8.1 Pregnancy Risk Summary Available data with OTEZLA use in pregnant women have not identified a drug-associated risk of major birth defects or adverse maternal or fetal outcomes (see Data ) . In animal embryo-fetal development studies, the administration of apremilast to pregnant cynomolgus monkeys during organogenesis resulted in dose-related increases in abortion/embryo-fetal death at dose exposures approximately 2-times the maximum recommended human therapeutic dose (MRHD) and no adverse effect at an exposure of 1.4-times the MRHD. When apremilast was administered to pregnant mice during organogenesis, there were no apremilast-induced malformations up to exposures 4-times the MRHD. Based on findings from animal reproduction studies, OTEZLA/OTEZLA XR may increase the risk for fetal loss (see Data ) . Advise pregnant women of the potential risk of fetal loss. The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, 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. Data Human Data A pregnancy registry conducted by the Organization of Teratology Information Specialists (OTIS) in the United States and Canada assessed the risk of major birth defects in liveborn infants of women with psoriatic arthritis, psoriasis, or Behçet's Disease exposed to apremilast in the first trimester. The study compared pregnant women treated with apremilast (n = 15) with disease matched pregnant women who were not exposed to apremilast (n = 106). In the apremilast-exposed cohort, there were no reports of liveborn infants with major birth defects nor miscarriages. One stillbirth was reported in the apremilast exposed cohort. These data are limited by the small sample size of apremilast-exposed pregnancies. Animal Data In an embryo-fetal developmental study, pregnant cynomolgus monkeys were administered apremilast at doses of 20, 50, 200, or 1000 mg/kg/day during the period of organogenesis (gestation Days [GD] 20 through 50). There was a dose -related increase in spontaneous abortions, with most abortions occurring during Weeks 3 to 4 of dosing in the first trimester, at doses approximately 2-times the MRHD and greater (on an area under the curve [AUC] basis at doses ≥ 50 mg/kg/day). No abortifacient effects were observed at a dose approximately 1.4-times the MRHD (on an AUC basis at a dose of 20 mg/kg/day). Although there was no evidence for a teratogenic effect at doses of 20 mg/kg/day and greater when examined at Day 100, aborted fetuses were not examined. In an embryo-fetal development study in mice, apremilast was administered at doses of 250, 500, or 750 mg/kg/day to dams during organogenesis (GD 6 through 15). In a combined fertility and embryo-fetal development study in mice, apremilast was administered at doses of 10, 20, 40, or 80 mg/kg/day starting 15 days before cohabitation and continuing through GD 15. No teratogenic findings attributed to apremilast were observed in either study; however, there was an increase in post-implantation loss at doses corresponding to a systemic exposure of approximately 2-times the MRHD and greater (≥ 20 mg/kg/day). At doses of ≥ 20 mg/kg/day skeletal variations included incomplete ossification sites of tarsals, skull, sternebra, and vertebrae. No effects were observed at a dose approximately 1.3-times the MRHD (10 mg/kg/day). Apremilast distributed across the placenta into the fetal compartment in mice and monkeys. In a pre …

12.1 Mechanism of Action Apremilast is an oral small molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP). PDE4 inhibition results in increased intracellular cAMP levels. The specific mechanism(s) by which apremilast exerts its therapeutic action is not well defined.
