Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief 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.
