Reports positive early clinical experience from first and only clinically validated, extracellular protein degraders using Biohaven's proprietary MoDE™ and next-generation, highly selective TRAP™ degraders exclusively licensed from Yale University. Early clinical experience in patients demonstrates rapid removal of circulating disease-causing proteins, resulting in robust clinical improvement with a well-tolerated profile to date:
IgA Nephropathy (IgAN) Program: First dosing of BHV-1400 TRAP degrader in IgAN patients achieved early observations of both biomarker and clinical responses including: selective lowering of only the disease-causing galactose-deficient IgA1 (Gd-IgA1) while sparing off-target effects on healthy antibodies (IgA, IgM, IgE, IgG), resolution of blood in the urine (hematuria), deep reductions in proteinuria, and improvement in fatigue and kidney function (eGFR) within weeks.
Completed 4Q25 FDA meeting to align on pivotal IgAN study design; study to initiate in early 2026
Graves' Disease Program: First-in-patient clinical experience with BHV-1300, an IgG MoDE degrader, resulted in a complete suppression of disease-causing TSH receptor-stimulating antibodies with accompanying normalization of previously elevated thyroid hormones within weeks after dosing a patient with Graves' disease. BHV-1300 has shown the potential for best-in-class reductions of IgG, with maximum reductions of up to an 87% decrease from baseline within weeks of dosing.
Biohaven is planning a pivotal study of BHV-1300 in Graves' disease in 2026.
Advancement of Broad Degrader Portfolio: With clinical proof-of-concept now established, Biohaven is positioned to advance multiple next-generation degraders targeting high value immune-mediated disease indications and explore strategic partnerships to advance the breadth of this platform technology.
Announces preliminary data with opakalim, a selective Kv7 channel activator, in an ongoing open-label extension (OLE) clinical study in focal epilepsy.
Demonstrated clinically meaningful reductions in seizure frequency compared to pretreatment baseline. Specifically, the majority of participants treated with opakalim 75 mg once daily who completed at least 6 months of OLE treatment showed ≥50% reductions in seizure frequency compared to pretreatment baseline.
Well-tolerated in the OLE with a low incidence of central nervous system adverse events, representing a potential paradigm-shift for patients with a highly favorable and differentiated safety profile compared to other approved or investigational antiseizure medicines.
Pivotal results for opakalim in the treatment of focal epilepsy expected in 2026.
Announces initiation of obesity Phase 2 study with Biohaven's myostatin-activin inhibitor targeting high quality weight loss. Dosing began in 4Q 2025 with topline results expected in 2026
Taldefgrobep alfa, an inhibitor of the myostatin-activin II receptor signaling pathways, directly targets: fat reduction, increased lean muscle mass and improves in bone density while avoiding intolerable adverse effects.
Taldefgrobep-myostatin complexes also result in the inhibition of Activin E - ALK7 in adipocytes, thereby having a direct effect on reducing adipose tissue.
Taldefgrobep has demonstrated a highly favorable safety and tolerability profile in >700 clinical trial participants studied to date.
Highlights clinical progress with Biohaven's next generation antibody drug conjugates (ADCs) in oncology
Phase 1/2 study evaluating BHV-1510 (Trop2 ADC) as monotherapy and in combination with Regeneron's anti-PD-1 monoclonal antibody cemiplimab shows continued clinical activity with confirmed responses and a differentiated safety profile in the ongoing study.
Endometrial cancer expansion cohort has been initiated with the combination of BHV-1510 and cemiplimab.
Initiated novel subcutaneous dosing with BHV-1510, first and only Trop2 ADC in clinic with potential subcutaneous route of administration.
First-in-class FGFR3 directed ADC, BHV-1530, continues with dose escalation and no dose limiting toxicities to date.
Advancements across portfolio of early clinical and next-generation future programs, including:
Pivotal clinical trial continues to advance enrollment with Biohaven's brain-penetrant TYK2/JAK1 inhibitor, BHV-8000 to treat early Parkinson's disease.
BHV-1955, a novel, long-acting intranasal formulation of oxytocin, for the central treatment of tinnitus.
BHV-8100, a brain-penetrant activator of the M2 isoform of pyruvate kinase (PKM2) for neurodegenerative disorders and aging.
