IgA nephropathy medical
"CLYM116 for the treatment of IgA nephropathy (IgAN)."
A kidney disease caused when deposits of the antibody called IgA collect in the tiny filters of the kidney, gradually reducing their ability to clear waste — like grit building up in a water filter. It matters to investors because it creates demand for diagnostics, drugs and long‑term care, drives clinical trial activity and regulatory decisions, and can influence the financial outlook of companies in pharma, biotech, medical devices and health insurance.
primary membranous nephropathy medical
"PrisMN Phase 2 primary membranous nephropathy (pMN) trial, enrollment ongoing."
An autoimmune kidney disorder in which the immune system attacks the thin filtering layer of the kidney, causing protein to leak into the urine and, over time, reduced kidney function—imagine tiny coffee filters developing holes and letting grounds through. It matters to investors because it shapes demand for diagnostics and therapies, drives clinical trials and regulatory decisions, and can influence drug revenues, treatment costs and insurer exposure tied to chronic kidney disease outcomes.
immune thrombocytopenia medical
"Phase 1b data in previously treated immune thrombocytopenia (ITP) patients"
Immune thrombocytopenia is a blood disorder in which the body's immune system mistakenly destroys platelets, the small cells that help blood clot, causing easy bruising, bleeding and a low platelet count. Investors care because the condition drives demand for diagnostic tests, treatments and clinical trials, affects regulatory and reimbursement decisions, and can influence revenue and risk profiles for companies developing therapies—think of it as the immune system removing the repair crew needed to stop leaks.
systemic lupus erythematosus medical
"Phase 1b/2a trial of budoprutug in systemic lupus erythematosus (SLE)"
Systemic lupus erythematosus is a chronic autoimmune disease in which the body's immune system mistakenly attacks healthy tissue, causing inflammation that can affect skin, joints, kidneys, heart, lungs and other organs. It matters to investors because disease severity, prevalence, and gaps in effective treatments drive demand for new drugs and diagnostics—think of it as a large, persistent market need where a successful therapy can change patient outcomes and create significant commercial value.
Orphan Drug Designation regulatory
"Budoprutug has been granted Orphan Drug Designation and Fast Track Designation"
Orphan drug designation is a special status given to medicines developed to treat rare diseases affecting only a small number of people. This status often provides benefits like faster approval processes and financial incentives, making it more attractive for companies to develop these drugs. For investors, it signals potential for exclusive market rights and reduced competition, which can impact the drug’s profitability.
A Proliferation-Inducing Ligand medical
"CLYM116 is a monoclonal antibody targeting APRIL (A Proliferation-Inducing Ligand)"
Cash, cash equivalents and marketable securities $239.2 million Company expects this balance to fund operations into the second half of 2028
R&D expenses Q2 2026 $9.7 million compared to $6.6 million for the three months ended June 30, 2025

WELLESLEY HILLS, Mass., August 6, 2026 (GLOBE NEWSWIRE) -- Climb Bio, Inc. (Nasdaq: CLYM), a clinical stage biotechnology company developing therapeutics for patients with immune-mediated diseases, today reported financial results for the second quarter ended June 30, 2026, and provided business updates.

 

“2026 is proving to be a defining year for Climb Bio, and I am thrilled by the team’s execution ,” said Aoife Brennan, M.B., Ch.B., President and Chief Executive Officer of Climb Bio. “We achieved important milestones for both budoprutug and CLYM116 over the past few months, and that momentum continues into the second half of the year with further data readouts across all four of our ongoing trials and the initiation of a Phase 2 trial of CLYM116 in IgAN patients. Currently at the forefront, I look forward to sharing initial Phase 1 data from CLYM116 in our September R&D Spotlight, where we will further highlight its potential as a best-in-class anti-APRIL antibody and provide additional details on our development strategy. With our continued progress across our pipeline, and supported by our strengthened balance sheet, we are well positioned to continue to execute on our strategic priorities and rapidly advance both programs toward pivotal development, setting the stage for what we believe will be an exciting 2027 for Climb.”

 

CLYM116 Program Updates and Anticipated Milestones

CLYM116 R&D Spotlight to be held on September 3, 2026. The Company will host a webcast to review the initial Phase 1 PK/PD data and development plans for CLYM116 for the treatment of IgA nephropathy (IgAN).
Presented CLYM116 initial Phase 1 safety data and translational PK/PD modeling at the European Renal Association (ERA) Congress in June 2026. Clinical data demonstrated a favorable initial safety profile and supported continued development of CLYM116 for IgA nephropathy (IgAN). Anticipate additional Phase 1 data at a medical meeting in the fourth quarter of 2026.
Mabworks Phase 1/2 study, enrollment ongoing. The Phase 1/2 trial being conducted by the Company's partner, Beijing Mabworks Biotech Co., Ltd., is ongoing, with dosing of IgAN patients in the Phase 2 portion expected to begin in the third quarter of 2026. Anticipate initial Phase 1 data at an upcoming medical meeting, and initial Phase 2 data in 2027.

 

Budoprutug Program Updates and Anticipated Milestones

PrisMN Phase 2 primary membranous nephropathy (pMN) trial, enrollment ongoing. PrisMN is a global open-label, dose-ranging Phase 2 study designed to evaluate pharmacodynamics (including B cells, anti-PLA2R, and total immunoglobulin) and preliminary efficacy (including complete and partial remission) in pMN patients with persistent proteinuria despite optimized renin-angiotensin-aldosterone system (RAAS) inhibition, and to identify a dose for Phase 3 clinical development. Enrollment is now ongoing in the second cohort (600 mg) and anticipate initial data, including preliminary B cell and anti-PLA2R data from low dose cohort (200mg at 12-24 weeks), at a medical meeting in the fourth quarter of 2026.
Presented initial Phase 1b data in previously treated immune thrombocytopenia (ITP) patients at European Hematology Association Congress in June 2026. Initial safety data from the 250 mg and 500 mg cohorts demonstrated favorable safety and tolerability, and initial efficacy data from the 250 mg cohort demonstrated robust B-cell depletion, and encouraging platelet responses. These data support continued development of budoprutug across multiple autoimmune indications. Anticipate additional data from the 500 mg and 1000 mg cohorts in the fourth quarter of 2026.

 

First patient dosed in China Phase 1b/2a trial of budoprutug in systemic lupus erythematosus (SLE); Global Phase 1b SLE trial enrollment ongoing.The global, open-label, dose-escalation Phase 1b trial of budoprutug in moderate to severe SLE is designed to evaluate safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy, including B-cell depletion, autoantibody levels, and clinical activity. The parallel China Phase 1b/2a trial in SLE is anticipated to provide complementary data and will also seek to enroll SLE patients with lupus nephritis. Data from these trials are expected to provide insights into budoprutug activity and will also help to inform future development efforts for the program broadly. Anticipate data, including safety and biomarker data from the Global study in the fourth quarter of 2026.
Presented positive topline data for subcutaneous (SC) formulation of budoprutug at Company R&D Spotlight in May 2026. The SC formulation of budoprutug was generally safe and well-tolerated and resulted in robust B-cell depletion, which was similar to the IV formulation at a matched dose. The results support the advancement of the SC formulation to a multiple dose study in autoimmune disease patients to evaluate full B-cell depleting doses and optimal dosing regimen. Plan to initiate a multiple-dose study of the SC formulation in autoimmune patients; anticipate initial data in 2027.

About Climb Bio, Inc.
Climb Bio, Inc. is a clinical-stage biotechnology company with a mission to deliver high impact, disease-modifying medicines for individuals living with immune-mediated diseases, including those affecting kidney health. The Company’s pipeline includes, budoprutug, an anti-CD19 monoclonal antibody that has potential to treat a broad range of B-cell mediated diseases, and CLYM116, an anti-APRIL monoclonal antibody being developed for IgA nephropathy. For more information, please visit
climbbio.com.

 

About Budoprutug
Budoprutug is a clinical-stage, anti-CD19 monoclonal antibody with the potential 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 plasmablasts and certain plasma cells, key sources of pathogenic autoantibodies. Early clinical data suggest budoprutug may offer durable B-cell depletion, rapid reductions in autoantibodies, and clinical remission in primary membranous nephropathy (pMN). Budoprutug is being evaluated in clinical trials for pMN, immune thrombocytopenia (ITP), and systemic lupus erythematosus (SLE). A subcutaneous formulation is also in development to enable broader patient access. Budoprutug has been granted Orphan Drug Designation and Fast Track Designation by the FDA for the treatment of pMN.

 

About CLYM116

CLYM116 is a clinical-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 ‘sweeper’ 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) and may also have broader utility across other B-cell mediated diseases where APRIL plays a critical role.
