A Novel Mechanism for the Treatment of Autoimmune Neurologic Diseases: Robust, Rapid, and Tunable Removal of IgG with the MoDE™ Degrader BHV-1300 (AAN 2026) - "BHV-1300 was safe and well-tolerated. Robust, rapid, and selective lowering of IgG was observed, highlighting the potential benefit as a treatment in acute and chronic antibody-mediated neurologic diseases. TRAP degraders that exclusively target specific pathogenic antibodies are also in development for the potential treatment of several antibody-mediated neurologic diseases."

Deep, Rapid, and Tunable IgG Removal with BHV-1300, Differentiated Small Molecule MoDE Degrader, Targeting the Autoimmune Etiology of Graves' Disease (ATA 2025) - "BHV-1300 was safe and well-tolerated and demonstrated target engagement, with median maximal reductions in IgG from baseline of up to 83% by day 18. Reductions at all doses occurred within hours of administration, were progressive, and effects were durable between dosing intervals. BHV-1300 was selective for IgG1, 2, and 4, with no clinically significant reduction in IgM, IgA, IgE, or IgG3 relative to baseline."

Biohaven Reports Positive Degrader Data Achieving > 80% Sustained Reductions in Total IgG with Potential First-in-Class BHV-1300 (PRNewswire) - P1 | N=8 | ACTRN12624001129572 | Sponsor: Biohaven Therapeutics Limited | "Up to 84% reduction of total IgG was observed with a median reduction of 80% after subcutaneous weekly 1000 mg dosing in the ongoing Phase 1 study. Subcutaneous BHV-1300 achieved progressive reductions in IgG levels within hours of each weekly dose administration, and pharmacodynamic effects were sustained compared to baseline over the four-week period...BHV-1300 has been safe and well tolerated across the ongoing Phase 1 studies with subcutaneous doses now administered up to 2000 mg. Most adverse events (AEs) were mild and self-resolving, there were no discontinuations due to AEs related to study drug, and there were no serious or severe AEs...Biohaven reiterates its plans to initiate a Phase 2 study in Graves' disease in mid-2025."

Molecular Degraders of Extracellular Protein (MoDEsTM) Rapidly and Effectively Remove Interstitial IgG and Disease-Relevant Immune Complexes Through Endo-lysosomal Degradation in the Liver (ACR Convergence 2024) - "In these in vitro and in vivo studies, extracellular IgG degraders (BHV-1300/-1310) from the MoDE drug platform demonstrated the ability to remove interstitial IgG and disease-relevant immune complexes through endo-lysosomal degradation in the liver. This new modality offers an attractive and differentiated therapeutic strategy for treating a spectrum of autoimmune conditions by targeting pathogenic autoantibodies and immune complexes that play a critical role in disease onset, progression and end organ damage."

Novel IgG Degrader BHV-1300 Demonstrates the Ability to Remove Anti-bDMARD ADA and Allows for Co-administration with Fc-containing Biologics (ACR Convergence 2024) - "These data demonstrate BHV-1300 does not adversely affect exposure to adalimumab and that it can reduce neutralizing ADAs. MoDE IgG degraders can be co-administered with bDMARDs in RA. Thus, MoDE degraders offer a unique combinatorial therapeutic approach for difficult to treat RA and other rheumatologic diseases, enabling removal of ADAs, pathogenic autoantibodies, and immune complexes as key differentiated features compared to other approaches."

PHARMACOKINETICS OF ADALIMUMAB IN CYNOMOLGUS MONKEYS FOLLOWING DOSING WITH BHV-1300, A FIRST-IN-CLASS MOLECULAR DEGRADER OF IgG (EULAR 2024) - "These data demonstrate that BHV-1300 does not adversely affect exposure to adalimumab and provide supporting evidence that MoDE IgG degraders such as BHV-1300 can be effectively used in combination with biological DMARDs in the management of difficult-to-treat autoimmune diseases. These results represent a key differentiating feature from neonatal Fc receptor inhibitors, which adversely affect the exposure to and effectiveness of, and cannot be co-administered with, Fc-containing biologics, including adalimumab. Moreover, BHV-1300 potentially offers a significantly improved benefit-risk based on other important mechanistic advantages including rapid onset of IgG-lowering, shortened time to maximal effect, depth of IgG lowering, brief period of exposure, potential for reduced immunosuppression, and lack of effects on albumin, cholesterol or triglycerides."

Novel Bispecific Degrader BHV-1300 Achieves Rapid, Robust, and Selective IgG Reduction in Preclinical Models Including Nonhuman Primates (AAN 2024) - "BHV-1300 demonstrated rapid, robust, safe, and selective IgG reductions in monkeys and rabbits. This compares favorably to published data for FcRn inhibitor IgG reducing therapies; BHV-1300 has important differentiating properties: speed of onset, shortened time to maximal effect, depth of IgG lowering, ability to be co-administered with biologics and target-related safety. Coupled with other potential mechanistic advantages (brief period of exposure; lack of effects on albumin, cholesterol, or triglycerides; potential for reduced immunosuppression; and compatibility with Fc-containing biologics), BHV-1300 represents the first member of a new drug class with potentially significantly improved benefit-risk for neuroinflammatory and autoimmune disorders including acute manifestations (MG crises/flares) or chronic disease (MG, rheumatoid arthritis, etc)."
