Study to Evaluate Safety and Efficacy of Oral MP1032 in Psoriasis Patients

Phase 2

Completed

Conditions: Psoriasis
Plaque Psoriasis

Interventions: Drug: Placebo
Drug: MP1032

Registration Number: NCT02908347

Lead Sponsor: MetrioPharm AG

Brief Summary: This Phase IIa study is designed to assess the safety, tolerability and pharmacokinetics of oral MP1032 in patients with moderate to severe psoriasis over a period of 6 weeks. Secondary endpoints to evaluate clinical parameters for psoriasis during the 6 week treatment period and a 4-week follow up will provide an opportunity to perform a first assessment of oral MP1032's clinical efficacy in the treatment of moderate to severe psoriasis.

The study population will consist of 44 enrolled (40 completed) patients with moderate to severe chronic plaque psoriasis. Patients must be able to provide written consent and meet all the inclusion criteria and none of the exclusion criteria.

Detailed Description: This study is a randomized, double-blind, parallel, placebo-controlled exploratory pilot study to evaluate safety, pharmacokinetics and efficacy of systemic oral (po) administration of 100 mg MP1032 bid in adult patients with moderate to severe chronic plaque psoriasis.

The study design consists of a 28-day screening/run-in period, a 42-day treatment period, 1 day for the End of Treatment visit, and a 28-day follow-up period. Forty-four patients who meet the entry criteria will be randomized on Day 1 in a 1:1 ratio to receive either 100 mg MP1032 or placebo orally twice daily for 42 days. The goal is to have 40 patients (20 in each treatment group) complete the study.

Pharmacokinetic sampling will occur on 3 designated study days. Safety will be monitored from the signing of the informed consent form (ICF) until the last follow-up visit on Day 71.

Efficacy will be assessed on 6 designated study days using the following assessments: PASI, PGA, DLQI, mNAPSI, and EQ-5D 5L (VAS).
