NJ-CELGENE

Celgene Corporation (NASDAQ:CELG) today announced that findings from ongoing clinical trials of OTEZLA^® (apremilast), the Company's oral, selective inhibitor of phosphodiesterase 4 (PDE4), conducted in patients with moderate or moderate to severe plaque psoriasis, and in adult patients (18 years or older) with active psoriatic arthritis, will be presented at the 75^th Annual Meeting of the American Academy of Dermatology (AAD) in Orlando, Florida. Ten abstracts will be presented at the meeting.

Among the data that will be presented is an analysis of the phase 4 UNVEIL trial, which evaluates the clinical efficacy and safety of oral OTEZLA 30 mg twice daily compared with placebo at week 16 in patients with moderate plaque psoriasis [defined as a body surface area (BSA) involvement of 5-10 percent and a static Physician’s Global Assessment (sPGA) of 3] who were naïve to systemic and biologic therapy. At baseline, more than 80 percent of patients enrolled in the trial had previously received topical therapy.

"We are excited to present new clinical research to the scientific community at AAD showing the efficacy and safety of OTEZLA in a variety of studies in patients with plaque psoriasis, including longer-term data," said Scott Smith, President, Celgene Inflammation & Immunology. “Furthermore, we are eager to share the results from UNVEIL, which is the first trial to evaluate a systemic therapy in patients with moderate plaque psoriasis who have not previously been treated with a systemic therapy, including biologics.”

The following abstracts will be presented at American Academy of Dermatology as an exchange of scientific and clinical information (all times, EST):

OTEZLA is not indicated for the treatment of plaque psoriasis patients with BSA involvement of less than 10 percent or sPGA less than 3.

About UNVEIL

UNVEIL is the first prospective, randomized, controlled study to evaluate the clinical efficacy and safety of OTEZLA in patients with moderate plaque psoriasis (defined as a BSA involvement of 5-10 percent and sPGA of 3 based on a 0 to 5 scale) who were naïve to systemic and biologic therapies. Patients (n=221) were randomized 2:1 to receive either OTEZLA 30 mg twice daily or placebo for 16 weeks, followed by an open-label extension phase in which placebo patients were switched to OTEZLA through week 52. All doses were titrated over the first week of treatment. At baseline, more than 80 percent of patients had previously received topical therapy. The primary endpoint was the mean percentage change from baseline in the product of Physician's Global Assessment (PGA) and BSA (%) at week 16.

About OTEZLA ^®

OTEZLA^® (apremilast) 30 mg tablets is an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP). PDE4 inhibition results in increased intracellular cAMP levels which is thought to indirectly modulate the production of inflammatory mediators. The specific mechanism(s) by which OTEZLA exerts its therapeutic action in patients with psoriasis or psoriatic arthritis is not well defined.

INDICATION

Otezla^® (apremilast) is indicated for the treatment of patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy and for the treatment of adult patients with active psoriatic arthritis.

IMPORTANT SAFETY INFORMATION

Contraindications

Otezla (apremilast) is contraindicated in patients with a known hypersensitivity to apremilast or to any of the excipients in the formulation.

Warnings and Precautions

Depression: Carefully weigh the risks and benefits of treatment with Otezla for patients with a history of depression and/or suicidal thoughts/behavior, or in patients who develop such symptoms while on Otezla. Patients, caregivers, and families should be advised of the need to be alert for the emergence or worsening of depression, suicidal thoughts or other mood changes, and they should contact their healthcare provider if such changes occur.

Psoriasis: Treatment with Otezla is associated with an increase in adverse reactions of depression. During clinical trials, 1.3% (12/920) of patients treated with Otezla reported depression compared to 0.4% (2/506) on placebo; 0.1% (1/1308) of Otezla patients discontinued treatment due to depression compared with none on placebo (0/506). Depression was reported as serious in 0.1% (1/1308) of patients exposed to Otezla, compared to none in placebo-treated patients (0/506). Suicidal behavior was observed in 0.1% (1/1308) of patients on Otezla, compared to 0.2% (1/506) on placebo. One patient treated with Otezla attempted suicide; one patient on placebo committed suicide.

Psoriatic Arthritis: During clinical trials, 1.0% (10/998) of patients treated with Otezla reported depression or depressed mood compared to 0.8% (4/495) treated with placebo; 0.3% (4/1441) of patients treated with Otezla discontinued treatment due to depression or depressed mood compared with none in placebo treated patients (0/495). Depression was reported as serious in 0.2% (3/1441) of patients exposed to Otezla, compared to none in placebo treated patients (0/495). Suicidal ideation and behavior were observed in 0.2% (3/1441) of patients on Otezla, compared to none on placebo (0/495). Two patients who received placebo committed suicide compared to none on Otezla.

Weight Decrease: Monitor body weight regularly; evaluate unexplained or clinically significant weight loss, and consider discontinuation of Otezla.

Psoriasis: Body weight loss of 5-10% occurred in 12% (96/784) of patients treated with Otezla and in 5% (19/382) of patients treated with placebo. Body weight loss of ≥10% occurred in 2% (16/784) of patients treated with Otezla compared to 1% (3/382) of patients treated with placebo.

Psoriatic Arthritis: Body weight loss of 5-10% was reported in 10% of patients taking Otezla and in 3.3% of patients taking placebo. Monitor body weight regularly; evaluate unexplained or clinically significant weight loss, and consider discontinuation of Otezla.

Drug Interactions: Apremilast exposure was decreased when Otezla was co-administered with rifampin, a strong CYP450 enzyme inducer; loss of Otezla efficacy may occur. Concomitant use of Otezla with CYP450 enzyme inducers (e.g., rifampin, phenobarbital, carbamazepine, phenytoin) is not recommended.

Adverse Reactions

Psoriasis: Adverse reactions reported in ≥5% of patients were (Otezla%, placebo%): diarrhea (17, 6), nausea (17, 7), upper respiratory tract infection (9, 6), tension headache (8, 4), and headache (6, 4).

Psoriatic Arthritis: Adverse reactions reported in ≥2% of patients taking Otezla, that occurred at a frequency at least 1% higher than that observed in patients taking placebo, for up to 16 weeks (after the initial 5-day titration), were (Otezla%, placebo%): diarrhea (7.7, 1.6); nausea (8.9, 3.1); headache (5.9, 2.2); upper respiratory tract infection (3.9, 1.8); vomiting (3.2, 0.4); nasopharyngitis (2.6, 1.6); upper abdominal pain (2.0, 0.2).

Use in Specific Populations

Pregnancy and Nursing Mothers: Otezla is Pregnancy Category C; it has not been studied in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether apremilast or its metabolites are present in human milk. Caution should be exercised when Otezla is administered to a nursing woman.

Renal Impairment: Otezla dosage should be reduced in patients with severe renal impairment (creatinine clearance less than 30 mL/min); for details, see Dosage and Administration, Section 2, in the Full Prescribing Information.
