HPP737 in Adult Patients With Moderate-to-severe Plaque Psoriasis.
A Multicenter, Randomized, Double-blind, Placebo-controlled Phase III Clinical Trial to Evaluate the Efficacy and Safety of Oral HPP737 in Adult Patients With Moderate-to-severe Plaque Psoriasis.
The goal of this clinical trial is to learn if drug HPP737 works to treat moderate-to-severe plaque psoriasis in adults. It will also learn about the safety of drug HPP737. The main questions it aims to answer are:
Does drug HPP737 improve psoriasis severity compared to a placebo at Week 16, as measured by the proportion of patients achieving a significant reduction in the Psoriasis Area and Severity Index (PASI) score? What medical problems do participants have when taking drug HPP737? Researchers will compare drug HPP737 to a placebo (a look-alike substance that contains no drug) to see if drug HPP737 works to treat moderate-to-severe plaque psoriasis.
This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical trial. Participants will:
Take drug HPP737 or a placebo orally every day Visit the clinic regularly for checkups and tests throughout the study Have their psoriasis severity assessed using standardized scoring tools, including the Psoriasis Area and Severity Index (PASI), static Physician's Global Assessment (sPGA), and Body Surface Area (BSA) Eligible participants are adults aged 18 years and older with a confirmed diagnosis of chronic plaque psoriasis for at least 6 months and moderate-to-severe disease at screening.

Descrizione dettagliata
HPP737-Psoriasis-301 is a phase III, multicenter, randomized, double-blind, parallel-group, placebo-controlled trial designed to evaluate the efficacy and safety of oral HPP737 in adult patients with moderate-to-severe plaque psoriasis. The study is sponsored by Newsoara Biopharma Co., Ltd. The trial involves approximately 504 patients across multiple centers nationwide.
HPP737 is a novel, potent, orally administered, and selective phosphodiesterase type 4 (PDE4) inhibitor. PDE4 is a validated therapeutic target for inflammatory diseases including psoriasis. By inhibiting PDE4, HPP737 raises intracellular cyclic adenosine monophosphate (cAMP) levels, thereby exerting broad anti-inflammatory effects. Preclinical and clinical data have demonstrated that HPP737 potently inhibits interleukin-23 (IL-23) and tumor necrosis factor alpha (TNF-α) production both in vitro and in vivo. Notably, HPP737 has shown a favorable safety and tolerability profile in phase I studies, with no dose-limiting gastrointestinal side effects-such as nausea, vomiting, or diarrhea-commonly associated with other PDE4 inhibitors.
This is a randomized, double-blind, placebo-controlled, parallel-group trial. Eligible patients are adults aged ≥18 years with a confirmed diagnosis of stable chronic plaque psoriasis for ≥6 months and moderate-to-severe disease at screening, defined by Psoriasis Area and Severity Index (PASI) score ≥12, static Physician's Global Assessment (sPGA) score ≥3, and body surface area (BSA) involvement ≥10%. Patients are randomized in a 1:1:1 ratio to one of three treatment arms: HPP737 10 mg once daily, HPP737 20 mg once daily, or placebo.
The total treatment duration is 52 weeks, divided into two phases:
Core Phase (Weeks 0-16): Patients receive double-blind treatment with HPP737 10 mg, HPP737 20 mg, or placebo.
Extension Phase (Weeks 16-52): Patients who complete the core phase enter the extension phase. Those originally assigned to placebo are switched to HPP737 20 mg; patients in the HPP737 10 mg and 20 mg groups continue on their assigned doses without adjustment.
The primary objective is to evaluate the efficacy of HPP737 compared with placebo at Week 16 in patients with moderate-to-severe plaque psoriasis. Secondary objectives include: (1) evaluation of additional efficacy characteristics of HPP737 versus placebo; (2) assessment of the safety of HPP737 in patients with moderate-to-severe chronic plaque psoriasis; and (3) evaluation of population pharmacokinetic (PPK) characteristics of HPP737 in this patient population.
The study is conducted in accordance with Good Clinical Practice guidelines and the Declaration of Helsinki.
