(Nasdaq: CLYM), a clinical stage biotechnology company developing therapeutics for patients with immune-mediated diseases, today reported financial results for the first quarter ended March 31, 2025, and provided business updates. “2025 is a critical year of execution for Climb Bio and we continue to make excellent progress developing a differentiated pipeline targeting immune-mediated diseases with expansive therapeutic and commercial potential,” said Aoife Brennan, President and CEO of Climb Bio. “Our most advanced program, budoprutug, a potential best-in-class anti-CD19 monoclonal antibody designed to treat B-cell mediated diseases, remains on track to initiate clinical studies in ITP and SLE in the coming weeks and in pMN in the second half of 2025. We plan to provide clarity on the anticipated timing of clinical readouts later this year when enrollment dynamics are clearer. In parallel, we are advancing the subcutaneous formulation of budoprutug and subject to regulatory clearance, anticipate initiating a Phase 1 clinical trial in healthy volunteers in the second half of the year.” Dr. Brennan continued, “We have also made progress with our CLYM116 program, a potential best-in-class anti-APRIL monoclonal antibody with potential to provide therapeutic benefit to patients living with IgA nephropathy and other B-cell mediated diseases. We look forward to sharing detailed preclinical data from the program, including pharmacokinetic and pharmacodynamic markers of biological activity, in the second half of 2025 and we anticipate submitting an investigational new drug (IND) or clinical trial application (CTA) for CLYM116 by year end.”  First Quarter 2025 and Recent Highlights FDA clearance for budoprutug Phase 2 pMN clinical trial. In March 2025, the Company announced that it had received clearance from the FDA to initiate a Phase 2 clinical trial of budoprutug in patients with pMN. This open-label, dose-ranging trial is designed to further evaluate the efficacy and safety of budoprutug in pMN.FDA clearance of budoprutug IND in ITP. In March 2025, the Company announced that it had received clearance from the FDA of its IND to initiate a Phase 1b/2a clinical trial of budoprutug in patients with ITP. In parallel, the Company is also pursuing ex-U.S. regulatory clearance for this clinical trial. This open-label, dose escalation and expansion trial is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary clinical efficacy of budoprutug in ITP. Pursuing ex-U.S. regulatory clearance for budoprutug clinical trial in SLE. Following the Company’s receipt of clearance from the FDA of its IND for SLE, the Company is also pursuing regulatory clearance to initiate the Phase 1b clinical trial of budoprutug in SLE at sites outside the United States. The open-label, single ascending dose study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary signs of clinical efficacy of budoprutug in SLE. Completed studies supporting a cell line switch for budoprutug. In March 2025, the Company announced that it was advancing the productivity and scalability of the manufacturing process for budoprutug to support later-stage clinical development.Expanded pipeline to include CLYM116, an antibody targeting the APRIL pathway for IgAN. In January 2025, Climb Bio entered into a technology transfer and exclusive license agreement with Beijing Mabworks Biotech Co., Ltd. (Mabworks) for the rights to develop and commercialize CLYM116 in the territory outside of Greater China. CLYM116 is a highly potent, Fc-engineered antibody that has the potential to enable more rapid, deep, and durable inhibition of APRIL signaling through its novel, pH-dependent mechanism of action. CLYM116 is currently in IND-enabling studies and the Company anticipates submitting an IND or CTA by year end.Appointed Kim Cobleigh Drapkin, CPA, and Bo Cumbo as Independent Directors in April 2025.

About Climb Bio, Inc.Climb Bio, Inc. is a clinical-stage biotechnology company developing therapeutics for patients with immune-mediated diseases. The Company’s pipeline includes, budoprutug, an anti-CD19 monoclonal antibody that has demonstrated B-cell depletion and has potential to treat a broad range of B-cell mediated diseases, and CLYM116, an anti-APRIL monoclonal antibody currently in IND-enabling studies for IgA nephropathy. For more information, please visit climbbio.com.  About BudoprutugBudoprutug is a clinical-stage, anti-CD19 monoclonal antibody being developed by Climb Bio to address a broad range of B-cell mediated, immune-driven diseases. Designed with enhanced effector function and low picomolar affinity, budoprutug targets and depletes CD19-expressing B cells, including plasma blasts that are key sources of pathogenic autoantibodies. Climb Bio plans to evaluate budoprutug in multiple clinical trials across three lead indications—primary membranous nephropathy (pMN), immune thrombocytopenia (ITP), and systemic lupus erythematosus (SLE)—which represent distinct mechanistic subtypes of immune-mediated disease. Early clinical data suggest budoprutug may offer durable B-cell depletion, rapid reductions in autoantibodies, and clinical remission in pMN. A subcutaneous formulation is also in development to enable broader patient access and potential home-based dosing. Budoprutug has been granted orphan drug designation by the FDA for the treatment of pMN. About CLYM116CLYM116 is a preclinical-stage monoclonal antibody targeting APRIL (A Proliferation-Inducing Ligand), a key driver of pathogenic B-cell activity in autoimmune diseases. CLYM116 employs a novel pH-dependent bind-and-release mechanism to potently block APRIL signaling, promote lysosomal degradation of APRIL, and recycle the antibody to extend its half-life. This differentiated design offers the potential for rapid, deep, and durable inhibition of APRIL with a favorable safety profile and less frequent dosing. CLYM116 is being advanced for the treatment of IgA nephropathy (IgAN), with plans to initiate a Phase 1 clinical trial following completion of IND-enabling studies and subject to regulatory clearance. The molecule may also have broader utility across other B-cell mediated diseases where APRIL plays a critical role.
