Apremilast meets psoriasis endpoints at week 32

SAN FRANCISCO – Apremilast met its primary endpoint at week 32 with no new or serious safety signals among patients with moderate to severe plaque psoriasis, according to phase III data from the ongoing LIBERATE study.

At week 16, 40% of patients who received oral apremilast achieved PASI-75, compared with 12% of the placebo group, Dr. Kristian Reich reported at the annual meeting of the American Academy of Dermatology.

By week 32, PASI-75 response for apremilast had further risen to 53%, he added. “This drug may not be a quick fix, but the longer you give it, the higher the response,” said Dr. Reich of SCIderm Research Institute and Dermatologikum Hamburg in Germany.

The randomized, double-blind LIBERATE study compared the safety and efficacy of apremilast (30 mg twice daily) and injectable etanercept (50 mg weekly) with placebo among 250 patients with plaque psoriasis who had not previously received biologic therapy. Patients received one of the three treatments through week 16, and then all were switched to or continued apremilast.

At week 16, PASI-75 response rates were 40% for apremilast, 48% for etanercept, and 12% for placebo (P < .0001 for apremilast versus placebo), reported Dr. Reich. The high rate of response to placebo might have occurred because patients in the study were treatment naive, he said. At week 32, PASI-75 response rates were 53% for patients who received apremilast from baseline, and 61% for patients who switched from etanercept to apremilast at week 16.

Based on the results, “I would probably use apremilast more in the moderate [psoriasis] space than in the severe space, but its efficacy does not correlate with baseline disease severity, as far as I know,” said Dr. Reich. Apremilast also beat placebo in analyses of secondary endpoints, including static physician global assessment of clear or almost clear and the Dermatology Quality of Life Index, he added.

Safety analyses showed that the drug was generally well tolerated. Fewer than 4% of patients discontinued treatment because of adverse events, the most common of which were diarrhea, nausea, vomiting, and headache (including tension headache). No new side effects emerged after patients switched from etanercept to apremilast at week 16, he said.

A post hoc analysis found that apremilast was noninferior to etanercept (P > .05) in terms of PASI-75, although the study was not powered to directly compare the two biologics, Dr. Reich noted.

Celgene Corporation makes apremilast and sponsored the study. Dr. Reich reported serving as a speaker for and receiving honoraria from Celgene.
