Comparison of Otezla to SFA-002 to Placebo in Plaque Psoriasis Patients

Phase 3Not Yet RecruitingNCT06863493

SFA Therapeutics125 enrolled

Overview

The goal of this clinical trial\] is to learn if SFA002 can treat mild, moderate and severe plaque psoriasis as good or better than Otezla, compared to placebo in adult and pediatric patients. The main questions it aims to answer are: How much does oral SFA002 treatment improve plaque psoriasis measured at different timepoints, 12 weeks, 24 weeks and 52 weeks of treatment. How much does Oral Otezla (Apremilast) improve plaque psoriasis measured at different timepoints, 12 weeks, 24 weeks and 52 weeks of treatment. These treatments will be compared to placebo, a look-alike substance that contains no drug. Participants will be randomly placed into 3 groups to receive either SFA002, or oral apremilast or placebo for the duration of the trial. Patients that do not respond to apremilast or placebo treatment in 12 weeks will be offered the opportunity to take SFA002 for the remainder of the study. There may be a higher burden for participants in this study compared to usual standard of care. Participants will attend regular visits per routine clinical practice. The effect of the treatment will be checked by medical assessments, checking for side effects, and questionnaires.

Inclusion Criteria:- 1. Candidates for systemic therapy with mild to moderate chronic plaque psoriasis (PsO) (with or without psoriatic arthritis) at Screening and Baseline for at least 6 months prior to Baseline defined as: 2. Body Surface Area (BSA) \>= 10% and \<= 15%; and Psoriasis Area and Severity Index (PASI) \>= 12; and Static Physician Global Assessment (sPGA) = 3 (moderate) based on a 5-point scale (0 to 4) - Exclusion Criteria: 1. Participant has any form of PsO other than chronic plaque PsO (e.g., pustular PsO, palmoplantar pustulosis, acrodermatitis of Hallopeau, erythrodermic, or guttate PsO). 2. History of current drug-induced PsO or a drug-induced exacerbation of pre-existing psoriasis. 3. History of active ongoing inflammatory skin diseases other than PsO and psoriatic arthritis that could interfere with the assessment of PsO (e.g., hyperkeratotic eczema). 4. Prior exposure to SFA002 or apremilast. -

Outcomes

Primary Outcomes

Percentage of Participants Achieving Psoriasis Area Severity Index (PASI) 90 (Defined as at Least 90% Improvement in PASI From Baseline) in Intent to Treat Population at Week 12 (ITT_A)

The PASI is used to evaluate a participant's overall psoriasis disease state that includes the percent of surface area of skin that is affected and the severity of erythema, induration, and desquamation over four body regions (head, upper extremities, trunk, and lower extremities). Scores range from 0 to 72, with higher scores indicating more severe disease.

Time frame: Week 12

Percentage of Participants Achieving Static Physician Global Assessment (sPGA) 0 or 1 With at Least 2-grade Improvement From Baseline in Intent to Treat Population at Week 12 (ITT_A)

The sPGA is the physician's current assessment of the average thickness, erythema, and scaling of all psoriatic lesions. Scores range from 0 (clear) to 4 (severe).

Time frame: 12 weeks

Percentage of Participants Achieving PASI 90 in Intent to Treat Population for Apremilast Non-Responders at Week 52 (ITT_B_NR)

Time frame: week 52

Secondary Outcomes

Percentage of Participants Achieving PASI 75 (Defined as at Least 75% Improvement in PASI From Baseline) in Intent to Treat Population at Week 12 (ITT_A)
