Clinical Trial Summary

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.
