Biohaven reported "compelling" results regarding its proprietary extracellular MoDE - BHV-1300 - and TRAP - BHV-1400 - degrader platform. Key highlights from the Phase 1b Graves' Disease patient experience with BHV-1300 include: weekly administration of BHV-1300 1000 mg achieved mean reductions of pathogenic TSHR-IgG1 of greater than 80% by week 12 in patients with Graves' hyperthyroidism, a deeper reduction than demonstrated with the competition; patients with elevated thyroid hormones experienced a normalization of free T4 at a median of 3 weeks and a normalization of free T3 within a median of 5 weeks, with reported improvements in classic symptoms of hyperthyroidism. BHV-1300 has been safe and well-tolerated through 12 weeks of dosing. BHV-1300 preserved the immune protection that FcRn inhibitors have not demonstrated. Biohaven is advancing BHV-1300 to a pivotal trial in Graves' disease in the coming weeks. Key highlights from the Phase 1b IgA nephropathy disease patient experience with BHV-1400 include: administration of BHV-1400 achieved deep, rapid, and sustained mean reductions of pathogenic Gd-IgA1 of greater than 60% within 48 hours of subcutaneous administration and 70% within the one month of dosing in patients with IgAN; participants also subjectively reported improvements in fatigue. BHV-1400 has been safe and well-tolerated throughout one month of dosing. Biohaven plans to study BHV-1400 in patients with IgAN, initiating a pivotal trial in mid-2026 designed to support regulatory approval.
