NEW HAVEN, Conn., Aug. 11, 2025 /PRNewswire/ -- Biohaven Ltd. (NYSE: BHVN) (Biohaven or the Company), a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies to treat a broad range of rare and common diseases, today reported financial results for the second quarter ended June 30, 2025, and provided a review of recent accomplishments and anticipated upcoming developments.

Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "As we eagerly await a regulatory decision on the VYGLXIA® (troriluzole) NDA for spinocerebellar ataxia, Biohaven has made important progress on multiple clinical stage assets this quarter, highlighted by the momentum we showcased at our recent R&D Day, where we unveiled advancements across our innovative therapeutic platforms." Dr. Coric added, "We are excited about the prospects of launching the first treatment for SCA if VYGLXIA is approved by the FDA and our commercial team is taking the appropriate steps to ensure an efficient launch to meet this high unmet need. We are also enthusiastic about the progress made across our Inflammation and Immunology (I&I) platform where we have observed compelling evidence of targeted protein degradation with our MoDE and TRAP degraders, BHV-1300 and BHV-1400. The body of evidence we have presented to date, combined with the safety profiles observed and convenient subcutaneous administration, continues to support our belief in our degrader platform's ultimate potential in addressing a range of immune-mediated diseases. We are also very pleased with the advancement of another key pillar of our I&I platform -- the brain-penetrant, TYK2/JAK1 inhibitor, BHV-8000, which has the potential to revolutionize the treatment of neuroinflammatory and neurodegenerative diseases. We initiated a pivotal Phase 2/3 study in Parkinson's disease, an unrelenting illness for which there is an urgent need for novel therapies to halt the progression of the disease."

Dr. Coric continued, "We also continue to take bold steps in other therapeutic areas to address important unmet medical needs for patients including in our Ion Channel and Oncology platforms. Our Kv7 platform continues to advance clinical programs toward completion in epilepsy and depression, and we are pleased to hear the promising early observations of a DEE pediatric patient successfully transitioned from ezogabine to opakalim.  Finally, our Oncology platform is also generating early promising clinical data, demonstrating tumor reduction in the first 6 out of 6 patients treated with BHV-1510 plus cemiplimab. Our oncology team has also been the first to advance an FGFR3-directed ADC with potential application in urothelial cancers into clinical testing."

"Biohaven is committed to following cutting edge science to attempt to help patients across multiple areas of high unmet need. For the balance of the year, we expect to deliver continued excellence in study execution and patient enrollment across key trials in our portfolio, as well as prepare for the potential commercialization of VYGLXIA in SCA if approved. We believe the SCA data supports approval in this rare, progressive and fatal indication for which no other treatments are available. Biohaven is well-positioned to execute on our commitment to transforming the treatment landscape for patients with serious and underserved diseases and we are excited to deliver on our promise to advance our programs for patients, caregivers, and shareholders in the balance of the year."

Second Quarter 2025 and Recent Business Highlights

• Released new data with MoDE (Molecular Degrader of Extracellular Proteins) program: In May 2025, the Company released new positive data from the Phase 1 study of BHV-1300, a MoDE initially being developed for the treatment of common immune-mediated diseases, such as Graves' disease and rheumatoid arthritis. In the Phase 1 multiple-dose study, subcutaneous administered BHV-1300 achieved IgG reductions up to 87%. Median maximum reductions of 83% were achieved within 18 days. The range of IgG lowering enabled by different dose levels of BHV-1300 potentially offers tunability and flexibility in dosing paradigm, with higher doses planned for management of acute conditions, and lower, less frequent dosing planned for the management of chronic disease.
• Released new data with TRAP (Targeted Removal of Aberrant Protein) degrader program: In May 2025, the Company announced further data from the Phase 1 study of BHV-1400, a TRAP degrader initially being developed to target Gd-IgA1, the aberrant immunoglobulin that drives IgA Nephropathy. In the Phase 1 study, a single dose of BHV-1400 was subcutaneously administered at a dose of 500 mg and achieved rapid, deep and sustained reductions in Gd-IgA1 of up to 81%, with a median reduction of 66%. Reductions occurred within hours of each dose, were progressive, and were sustained for weeks after a single dose administration. Effects were selective, with no significant reductions observed in other immunoglobulins (IgA, IgG, IgE, or IgM).
• Demonstrated early clinical activity and favorable PK profile with BHV-1510: In May 2025, the Company announced early clinical results from a Phase 1 study of BHV-1510, a next-generation Trop2-directed ADC incorporating the proprietary TopoIx payload. The data demonstrated early signs of clinical activity and a differentiated, manageable safety profile, both as monotherapy and in combination with Regeneron's anti-PD-1, cemiplimab. Partial responses were observed across multiple tumor types with BHV-1510 monotherapy, accompanied by low rates of payload-related toxicities. The most common adverse event was stomatitis, an anticipated and manageable class effect associated with Trop2-targeted therapies. Notably, tumor reduction was seen in all six of the first patients treated with the BHV-1510 and cemiplimab combination, including confirmed partial responses. The combination regimen was well tolerated, with no dose-limiting toxicities or cases of interstitial lung disease reported in these initial cohorts. These encouraging early clinical data, along with the favorable pharmacokinetic profile and proprietary stable linker technology, support continued investigation of BHV-1510 as monotherapy and in combination with cemiplimab in difficult-to-treat tumor types, including potential evaluation in earlier lines of therapy for patients with advanced or metastatic disease.
• First patient dosed with Biohaven's TopoIx ADC, BHV-1530: In May 2025, the Company commenced dosing with BHV-1530, a potential first-in-class fibroblast growth factor receptor 3 (FGFR3)-directed ADC which utilizes the proprietary Topolx payload. BHV-1530 has potential in cancer indications driven by FGFR3 alterations and/or upregulated FGFR3 protein expression, including urothelial cancers and other solid tumors.
• Phase 2/3 PD trial initiated: In May 2025, the Company commenced enrollment in a global, pivotal, Phase 2/3 study of the first-in-clinic, orally-administered, brain-penetrant, and highly selective TYK2/JAK1 inhibitor, BHV-8000, for the treatment of early Parkinson's disease (PD).
• Compassionate use of opakalim (BHV-7000) in a child with intractable epilepsy due to Kv7 gene mutation (KCNQ2 Developmental and Epileptic Encephalopathy [KCNQ2-DEE]) provides early evidence of potential clinical benefit. A child with KCNQ2-DEE and a history of intractable epilepsy who was previously maintained on ezogabine, as well as other antiepileptics, was successfully transitioned to treatment with opakalim, Biohaven's next-generation Kv7 activator. Opakalim was administered after receiving a compassionate use request, under a single patient IND approved by the FDA, as the child was being withdrawn from ezogabine treatment. The child had multiple unsuccessful attempts in the past to taper ezogabine, leading to severe seizure exacerbations requiring admission to the hospital intensive care unit. Dosing of opakalim in this pediatric patient was selected to achieve comparable exposures as the 75mg dose being investigated in ongoing Phase 2/3 clinical trials. Following the transition, the patient demonstrated signs of therapeutic benefit as assessed by initial seizure control and a favorable side effect profile. Although generalizability of these observations is limited, given it represents a single case report of treating a KCNQ2-DEE patient and a short initial follow-up period after transition from ezogabine, the early clinical experience after initiation of opakalim, a selective Kv7 activator, is promising for its observed antiseizure effects and favorable tolerability.
• Phase 3 trial in OCD with troriluzole was completed with no efficacy signal detected. The OCD development program is being ended to allow resources to be applied to other development programs. Study results will be presented at an upcoming academic meeting.

Capital Position:

Cash, cash equivalents, marketable securities and restricted cash as of June 30, 2025 totaled approximately $408.2 million.

Second Quarter 2024 Financial Highlights:

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $184.4 million for the three months ended June 30, 2025, compared to $314.8 million for the three months ended June 30, 2024. The decrease of $130.5 million was primarily due to a one-time non-cash expense during the three months ended June 30, 2024, paid to Knopp for a milestone and royalty buyback related to the BHV-7000 and broader Kv7 platform. The decrease was partially offset by increased direct program costs for advancing clinical trials and preclinical research programs in 2025, including one-time developmental milestone payments of $15.0 million and $10.0 million for our BHV-8000 and BHV-1530 programs, respectively, as well as increased non-cash share-based compensation expense. Non-cash share-based compensation expense was $13.1 million for the three months ended June 30, 2025, an increase of $6.0 million as compared to the same period in 2024. Non-cash share-based compensation expense was higher in 2025 primarily due to our annual equity incentive awards granted in the first quarter of 2025.

General and Administrative (G&A) Expenses: G&A expenses, including non-cash share-based compensation costs, were $27.3 million for the three months ended June 30, 2025, compared to $19.0 million for the three months ended June 30, 2024. The increase of $8.4 million was primarily due to increased non-cash share-based compensation expense and increased expenses related to fees incurred in connection with the Note Purchase Agreement with Beetlejuice SA LLC, an affiliate of Oberland Capital Management LLC, entered into during the second quarter of 2025 (the Note Purchase Agreement) and other legal costs. Non-cash share-based compensation expense was $7.7 million for the three months ended June 30, 2025, an increase of $2.5 million as compared to the same period in 2024. Non-cash share-based compensation expense was higher in 2025 primarily due to our annual equity incentive awards granted in the first quarter of 2025.

Other Income, Net: Other income, net was $13.8 million for the three months ended June 30, 2025, compared to other income, net of $14.2 million for the three months ended June 30, 2024. The decrease of $0.4 million was primarily due to decreased investment income and an increase in non-cash losses related to changes in fair value of our notes payable liability under the Note Purchase Agreement during the second quarter of 2025, partially offset by an increase in gains recorded for the non-cash changes in the fair value of our forward contract and derivative liability recorded in connection with the amendment to our Membership Interest Purchase Agreement with Knopp Biosciences LLC in May 2024 (the Knopp Amendment).

Net Loss: Biohaven reported a net loss for the three months ended June 30, 2025 of $198.1 million, or $1.94 per share, compared to $319.8 million, or $3.64 per share, for the same period in 2024. Non-GAAP adjusted net loss for the three months ended June 30, 2025 was $166.4 million, or $1.63 per share, compared to $308.6 million, or $3.52 per share, for the same period in 2024. These non-GAAP adjusted net loss and non-GAAP adjusted net loss per share measures, more fully described below under "Non-GAAP Financial Measures," exclude non-cash share-based compensation charges and losses from the change in fair value of derivatives. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below.

Non-GAAP Financial Measures
This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and certain non-GAAP financial measures. In particular, Biohaven has provided non-GAAP adjusted net loss and adjusted net loss per share, which are adjusted to exclude non-cash share-based compensation, which is substantially dependent on changes in the market price of common shares, and changes in the fair value of derivative liabilities, which do not correlate to actual cash payment obligations in the relevant periods. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, Biohaven believes the presentation of non-GAAP adjusted net loss and adjusted net loss per share, when viewed in conjunction with GAAP results, provides investors with a more meaningful understanding of ongoing operating performance and can assist investors in comparing Biohaven's performance between periods.

In addition, these non-GAAP financial measures are among those indicators Biohaven uses as a basis for evaluating performance, and planning and forecasting future periods. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between these non-GAAP measures and the most directly comparable GAAP measures is provided later in this news release.
