Abstract

Objective: Safe, effective, long-term oral therapies are needed for plaque psoriasis. This study aimed to assess the safety and effectiveness of tepilamide fumarate (a fumaric acid ester) extended-release tablets.

Methods: This Phase IIb, randomized, double-blind, placebo-controlled, 24-week, multicenter study treated adults with moderate-to-severe plaque psoriasis with tepilamide fumarate 400 mg once (QD) or twice daily (BID), 600 mg BID, or placebo. Coprimary endpoints were the proportion of patients achieving ≥75% reduction in the Psoriasis Area and Severity Index (PASI-75) and Investigator's Global Assessment (IgA) of clear or almost clear (≥2 points' reduction).

Results: A total of 426 patients were randomized (mean age 49.6 [±13.0] years). There was a ≥75% PASI reduction in 39.7%, 47.2%, 44.3%, and 20.0% in the 400 mg QD, 400 mg BID, 600 mg BID, and placebo groups, respectively; IgA treatment success was 35.7%, 41.4%, 44.4%, and 22.0%, respectively. Between 50%-66% of tepilamide fumarate and 48% of placebo patients experienced ≥1 treatment-emergent adverse event. Gastrointestinal intolerance (20%-42%), Infection (6%-18%), and decreased lymphocyte count (4%-9%) were more common with tepilamide fumarate.

Limitations: High placebo response somewhat limits the utility of these findings.

Conclusion: Patients with moderate-to-severe plaque psoriasis treated with oral tepilamide fumarate demonstrated positive response.
