Biohaven Unveils Breakthrough Data from MoDE and TRAP Platforms at R&D Day

On May 28th, 2025, Biohaven Ltd., a prominent biopharmaceutical company, conducted its R&D Day in New Haven, Connecticut, unveiling pivotal advancements in its TRAP and MoDE platforms. These technologies hold significant promise in treating IgA Nephropathy (IgAN) and other diseases by precisely targeting harmful proteins in the immune system. The event highlighted exceptional results from Biohaven's innovative TRAP Degrader, BHV-1400, cementing its potential as a first-in-class therapy.

Key Findings on BHV-1400

At the R&D event, Biohaven reported groundbreaking data demonstrating that BHV-1400 achieved sustained reductions exceeding 80% in Galactose-deficient IgA1 (Gd-IgA1), an immunoglobulin linked to IgAN. This efficacy was observed after a single subcutaneous dose, with notable reductions in Gd-IgA1 persisting for weeks. This rapid and profound action distinguishes BHV-1400 from current therapies, which often aim to suppress immune responses more broadly.

Dr. Jonathan Barratt, an esteemed professor of Renal Medicine at the University of Leicester and an expert in IgAN, praised BHV-1400, stating, “It specifically targets the fundamental abnormality in IgA nephropathy while leaving the rest of the immune system untouched.” He emphasized that by removing the main driver causing immune complex formation, BHV-1400 could act as a safer alternative to existing immunosuppressive treatments that can compromise overall immune function.

Clinical Perspectives

BHV-1400 is uniquely designed to selectively eliminate Gd-IgA1 while preserving healthy forms of immunoglobulins like IgA, IgG, IgE, and IgM, crucial for maintaining immune activity. Biohaven is gearing up to initiate pivotal clinical trials for BHV-1400 targeting IgAN in 2026, with the goal of securing accelerated approval based on urine protein-creatinine ratio (UPCR) as a surrogate endpoint.

In addition, clinical results from Phase 1 trials showed that adverse events associated with BHV-1400 were mild and self-resolving, demonstrating a favorable safety profile. Importantly, there were no significant impacts on liver enzymes or other immunoglobulin levels during the study, affirming BHV-1400's targeted approach.

Advancements with BHV-1300

Beyond BHV-1400, Biohaven also showcased data on its MoDE degrader, BHV-1300, designed to target IgG for removal. The recent Phase 1 trials revealed that BHV-1300 could achieve IgG reductions of up to 87% within 18 days, showcasing its rapid efficacy. This selective targeting allows for various dosing strategies, making it a versatile candidate for managing both acute and chronic conditions like Graves' Disease, for which pivotal trials are anticipated to start in the latter half of 2025.

Biohaven's Mission

Biohaven remains at the forefront of biopharmaceutical innovation, focusing on developing effective treatments for immune-mediated diseases using its advanced drug discovery platforms. The company aims to leverage cutting-edge biochemical technology to provide precision therapies that directly address the underlying causes of diseases, ensuring better outcomes for patients.

With exciting future prospects on the horizon, including significant clinical trials for BHV-1400 and BHV-1300, Biohaven is set to redefine treatment paradigms in immunology, enhancing the quality of life for individuals affected by complex conditions like IgA Nephropathy and Graves' Disease.
