Study to Evaluate APVO210 in Healthy Subjects, Patients With Psoriasis, and Patients With Ulcerative Colitis

Phase 1 Randomized, Double-Blind, Placebo-Controlled, Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of APVO210 in Healthy Subjects, Patients With Psoriasis, and Patients With Ulcerative Colitis

Phase 1 study in 2 stages with 2 expansion cohorts. The first stage is a single ascending dose (SAD) study of APVO210 in healthy volunteers. The second stage is a multiple ascending dose (MAD) study of APVO210 in healthy volunteers. Two expansion cohorts evaluate multiple doses of APVO210 in psoriasis patients and ulcerative colitis patients.
