Celgene Corporation, today announced that results from long-term (104-week) efficacy and safety analyses of OTEZLA® (apremilast) from the open-label phase of two PALACE phase III clinical trials were presented at the 2014 American College of Rheumatology (ACR)/Association of Rheumatology Health Professionals (ARHP) annual meeting in Boston. OTEZLA is the Company's oral, selective inhibitor of phosphodiesterase 4 (PDE4), approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with active psoriatic arthritis and for the treatment of patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy.

In PALACE 1, 84 percent (144/171) of patients who completed one year (52 weeks) of 30 mg twice daily therapy continued to receive OTEZLA at two years (104 weeks). Improvements in efficacy measures observed at 52 weeks were sustained through 104 weeks of treatment. At week 104, among patients receiving OTEZLA 30 mg twice daily, the ACR20 response rate was 65.3 percent. ACR50 and 70 response rates were 34.0 percent and 19.6 percent, respectively, at week 104.

Similar findings were observed in PALACE 4. In this trial, nearly 84 percent (168/201) of DMARD-naïve patients who completed one year of OTEZLA 30 mg twice daily monotherapy continued to receive OTEZLA at two years. At week 104, among patients treated with OTEZLA 30 mg twice daily monotherapy, an ACR20, 50 and 70 response was reached by 61.4 percent, 40.7 percent and 19.2 percent of patients, respectively.

In both PALACE 1 and PALACE 4, changes in other efficacy measures—including the HAQ-DI, which assesses improvements in physical function, and swollen and tender joint counts—were also generally sustained between weeks 52 and 104 with continued OTEZLA treatment. In PALACE 4, treatment with OTEZLA in patients with pre-existing enthesitis (inflammation at sites where tendons or ligaments insert into bone) or dactylitis (inflammation of an entire digit), two key manifestations of psoriatic arthritis, resulted in improvements in enthesitis and dactylitis that were sustained through 104 weeks of treatment.

"Given the chronic nature of this condition, dealing with psoriatic arthritis can be an ongoing struggle for many people," said Alvin Wells, M.D., Ph.D., director, Rheumatology and Immunology Center, Franklin, WI. "Evidence-based data show that different treatment options are frequently required to continue to manage a patient's symptoms. At our center, we see patients with active psoriatic arthritis who present with significant disease activity despite effective prior treatments. These new data from ongoing open-label studies add to our understanding of how apremilast may help meet treatment goals in such patients."

Similar to adverse events (AEs) reported during weeks 0 to 52 in PALACE 1 and 4, most AEs reported during weeks 52 to 104 were mild or moderate in severity. The rates of diarrhea, nausea, headache and upper respiratory tract infection (URTI)—AEs reported in at least five percent of patients receiving OTEZLA 30 mg twice daily at 52 weeks in both studies—decreased or were similar between weeks 52 to 104 compared with the 0 to 52 week period. Rates of diarrhea, nausea, headache and URTI at week 104 in PALACE 1 and 4 respectively, were as follows: diarrhea (1.8 percent and 2.0 percent), nausea (0.6 percent and 2.0 percent), headache (4.7 percent and 1.0 percent) and URTI (4.7 percent and 4.5 percent). Serious AEs occurred in 4.7 percent and 5.0 percent of patients, respectively. In addition, discontinuation rates due to AEs in both studies decreased during the 52 to 104 week period compared with the 0 to 52 week period.
