简要总结
The primary objective is to assess the safety and tolerability of 200 mg of belumosudil administered orally once daily for 28 days.
详细描述
This will be a Phase 2a, open-label, single-arm, safety and tolerability study of belumosudil given daily for treatment of psoriasis.
Eight subjects with moderately severe psoriasis who have failed at least 1 line of systemic therapy will be enrolled.
Treatment Period Eligible subjects who have failed at least 1 line of systemic therapy will be entered and treated for 4 weeks (28 days) with 200 mg of belumosudil given orally once daily (QD).
Subjects will undergo medical history evaluations, physical examinations, vital sign measurements, weight, adverse event assessments, concomitant medication assessments, and laboratory testing including but not limited to blood sample collection for hematology and chemistry, urinalysis, coagulation, lipid panel, electrocardiogram, pregnancy test for females of childbearing potential, testing with the Psoriasis Area and Severity Index (PASI) scale and Physician Global Assessment (PGA) scale, and pharmacokinetic sampling.
