AI Summary
Biohaven Ltd. presented promising Phase 1 results for BHV‑1400, its innovative therapeutic for IgA nephropathy, at the 43rd Annual J.P. Morgan Healthcare Conference. BHV‑1400, a second-generation TRAP™ degrader, quickly reduced the problematic antibody Gd‑IgA1—responsible for IgA nephropathy—by 60% within four hours and over 70% within eight hours after a single 125mg dose. Importantly, the drug selectively lowered only the disease-causing antibody while sparing normal immunoglobulins, indicating a more precise approach than existing therapies.
The treatment has been safe and well-tolerated so far, with no significant changes in white blood cell counts, immunoglobulins, liver tests, or cholesterol levels. These encouraging results suggest that BHV‑1400 could offer effective disease control with fewer risks, and a pivotal trial using an accelerated regulatory pathway is planned once Phase 1 is complete.
