A Randomized, Double-Blind, Placebo-Controlled, Phase 2a Study to Evaluate the Efficacy and Safety of RIST4721 in Subjects with Palmoplantar Pustulosis.

ABSTRACT:

Introduction

Palmoplantar pustulosis (PPP) is a chronic inflammatory skin condition with neutrophilic infiltration of the epidermis. RIST4721 antagonizes CXC chemokine receptor type 2, which is important in neutrophil recruitment and migration. In this study, the efficacy and safety of RIST4721 versus placebo were assessed in adult subjects with moderate to severe PPP.

Methods

This phase 2a, multicenter, randomized, double-blind, placebo-controlled study investigated RIST4721 versus placebo in subjects with moderate to severe PPP. Key eligibility criteria included: Palmoplantar Pustulosis Area and Severity Index (PPPASI) ≥ 8 and Palmoplantar Pustulosis Physician Global Assessment ≥ 3. Subjects were randomized 1:1 to RIST4721 300 mg or placebo once daily for 28 days. The prim
