Climb Bio, Inc. (NASDAQ: CLYM) Announces Initial Data from Phase 1b Study of Budoprutug in Primary Immune Thrombocytopenia (ITP)
Key Highlights
- Climb Bio, Inc. (formerly Eliem Therapeutics, Inc.) has released initial data from the ongoing Phase 1b portion of its Phase 1b/2a study evaluating budoprutug, an anti-CD19 monoclonal antibody.
- The study is focused on adult patients with primary immune thrombocytopenia (ITP), a rare autoimmune bleeding disorder characterized by low platelet counts.
- The Company expects to announce additional data from the study by year-end 2026.
- The initial results are aimed to inform dose and regimen selection, assess safety, and evaluate the depth and duration of platelet response and B-cell depletion.
Details of the Announcement
On June 11, 2026, Climb Bio, Inc. provided an update to investors regarding progress in its clinical pipeline, specifically focusing on budoprutug, a next-generation anti-CD19 monoclonal antibody. The current clinical trial is investigating the safety and efficacy of this therapy in adults diagnosed with primary ITP, a disease where existing treatment options are often limited and unsatisfactory.
The Company is leveraging the initial Phase 1b data to guide critical decisions on dosing and scheduling for subsequent phases of the study. This step is particularly important in drug development for rare diseases, where optimizing the therapeutic window can significantly impact both efficacy and safety outcomes.
According to the announcement, the ongoing trial is also evaluating the effect of budoprutug on B-cell depletion, a key biomarker in immune-mediated diseases like ITP. The preliminary safety data and the durability of platelet responses will be closely watched by both regulators and investors.
Climb Bio has indicated its intention to share further results from this clinical program by the end of 2026, suggesting a potentially significant catalyst for the company’s share price within the next 6-12 months.
