Researchers are evaluating budoprutug, a humanized monoclonal antibody targeting CD19, in adults with immune thrombocytopenia ITP, a condition characterized by low platelet counts. This Phase 1b2a open-label study aims to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary clinical effects of budoprutug in patients with platelet counts below 30,000L despite prior treatment attempts. The study is sponsored by Climb Bio, Inc. Participants will receive budoprutug as two intravenous infusions administered 14 days apart. The study includes sequential cohorts with escalating doses, followed by a dose expansion group. Each participant receives a single IV dose on Day 1 and another on Day 15. The trial monitors the effects of budoprutug on platelet counts and CD20 B-cell levels, among other factors. Throughout the study, participants will be closely monitored up to 48 weeks for treatment-related side effects, blood levels of the drug, immune cell changes, platelet responses, and the development of anti-drug antibodies. Safety labs including coagulation tests and bilirubin levels will be assessed. The study does not include placebo groups and participation involves scheduled visits for infusions and follow-up evaluations to track both safety and preliminary clinical outcomes over nearly a year.
