NEW HAVEN, Conn., Nov. 14, 2023 /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 third quarter ended September 30, 2023, and provided a review of recent accomplishments and anticipated upcoming milestones.

Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "Our team at Biohaven continued to make tremendous progress this past quarter in advancing multiple development programs and innovating across our entire pipeline. Most recently, we shared important data from our molecular degrader of extracellular proteins (MoDE™) program and demonstrated the potential for this technology in the field of immunology where targeting pathologic antibodies has been shown to have important therapeutic potential.  We have demonstrated that BHV-1300, our lead IgG degrader, has great potential with a differentiated profile including: rapid onset of action, deeper reductions in IgG levels compared to FcRN targeting agents, lack of anticipated mechanistic effects on albumin or cholesterol, potential for self-administered subcutaneous dosing, and the compatibility to dose in combination with standard of care biologic therapeutic agents. BHV-1300 offers a highly competitive mechanism of action and potential for favorable differentiation from FcRn targeting agents. In addition, our technology can be readily modified to expand therapeutic targets past IgG to include other immunoglobulins (IgA, IgM, IgE, etc) and antigen specific autoantibodies. With multiple opportunities to address rare and common diseases alike, we continue to be impressed by the expansive potential of our degrader program.

Beyond our extracellular degraders, we also shared key data from ongoing studies with BHV-7000, our highly selective Kv7.2/7.3 activator for epilepsy, mood disorders and pain. Consistent with results observed in clinical and non-clinical studies, EEG data reported last month confirmed CNS target engagement without showing waveform increases in frequencies typically associated with adverse events commonly associated with existing ASMs, such as somnolence and other CNS effects; we expect to present additional details and analyses from this EEG study at an upcoming scientific meeting soon. With target engagement now confirmed in EEG biomarker studies, a favorable safety profile demonstrated in Phase 1 studies, and development of a once-daily formulation of BHV-7000 complete, we look forward to initiating our Phase 3 program in focal epilepsy, which we expect to commence before the end of 2023 -- a program poised to offer paradigm shifting potential in preventing seizures without burdensome CNS side effects. Separately, we completed enrollment in RESILIENT, our Phase 3 pivotal study of taldefgrobep alfa in SMA in record time, thanks to our partnership with the global SMA community and the remarkably efficient clinical trial expertise that we have in-house at Biohaven."

Dr. Coric continued, "With the closing of our recent public offering and achievement of several important milestones across our programs, we are in a strong position with access to approximately $495 million in capital following our public offering this month to continue to invest in accelerating and executing on our innovative pipeline. Our unwavering patient focus and methodical scientific approach drives every layer of our decision making, and we will progress and phase programs to balance our commitment with prudent resource allocation."

Third Quarter 2023 and Recent Business Highlights

• Reported on continued progress with first-in-class bispecific IgG degrader, BHV-1300, as compound advances to IND submission by the end of 2023 - In September 2023, the Company announced preliminary analyses and positive pharmacodynamic data from a preclinical study evaluating BHV-1300 in cynomolgus monkeys. Repeat dosing of BHV-1300 produced dose-dependent reductions of over 90% in IgG levels from baseline, suggesting the potential for achieving greater efficacy with finely calibrated, deeper IgG reductions as compared with existing standard of care FcRn targeting treatments. The Company remains on track to submit an IND application for BHV-1300 in 2023; the Company also expects to submit an IND application for its first-in-class bispecific IgA degrader BHV-1400 in the second half of 2024.
• Public offering - On October 5, 2023, the Company closed its previously announced underwritten public offering of 11,761,363 of its common shares, which included the full exercise of the underwriters' option to purchase 1,534,090 additional shares, at the public offering price of $22.00 per share. The net proceeds raised in the offering, after deducting underwriting discounts and estimated expenses of the offering payable by the Company, were approximately $242.4 million. As of November 10, 2023, we had 80,233,656 common shares outstanding.
• Announced preliminary analyses and positive biomarker data from Biohaven's exploratory Phase 1 EEG biomarker study and completed once-daily formulation development - In September 2023, the Company announced preliminary analyses and positive biomarker data from its Phase 1 EEG biomarker study confirming CNS activity of BHV-7000 at projected therapeutic concentrations and drug concentration-dependent (i.e., dose-dependent and time-dependent) changes in EEG spectral power consistent with EEG effects observed with other ASMs approved for the treatment of epilepsy. BHV-7000 was well tolerated in the exploratory EEG study and the safety profile was consistent with the previously reported safety data from the Phase 1 SAD/MAD trial completed to date in healthy volunteers. The Company expects to share additional results from this EEG study at the upcoming American Epilepsy Society (AES) medical meeting in December.
• Successfully dosed three cohorts with single ascending doses of oral, brain penetrant, dual TYK2/JAK1 agent, BHV-8000 - In July 2023, the Company announced that it successfully dosed three cohorts in the SAD portion of an ongoing SAD/MAD Phase 1 study evaluating brain penetrant TYK2/JAK1 agent, BHV-8000 in healthy volunteers. The ongoing Phase 1 study is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple ascending doses of BHV-8000 in healthy volunteers. Based on the preliminary data available, projected therapeutic concentrations of BHV-8000 were achieved, and BHV-8000 was well tolerated with only mild adverse events reported. These data provide support for further development of BHV-8000, and the Company anticipates beginning a Phase 2/3 clinical trial with BHV-8000 in Parkinson's disease and potentially other neuroinflammatory diseases in 2024.
• Presented preclinical data demonstrating taldefgrobep alfa reduces fat and improves lean mass at ObesityWeek® - In October 2023, the Company announced the presentation of preclinical data demonstrating the ability of taldefgrobep alfa to significantly reduce fat mass while increasing lean mass in an obese mouse model at The Obesity Society's annual ObesityWeek conference. Separately, the Company reported data supporting the correlation between change in waist circumference and change in total body weight among adults living with overweight and obesity treated with approved anti-obesity medications.
• Completed enrollment in pivotal Phase 3 study of taldefgrobep alfa in SMA - In September 2023, the Company announced that it had completed enrollment in RESILIENT, a pivotal Phase 3 study designed to evaluate the efficacy and safety of taldefgrobep as adjunctive therapy to enhance muscle mass and function in SMA patients treated with standard-of-care treatments. Taldefgrobep is the only myostatin inhibitor in clinical development that targets both myostatin and activin A signaling, two key regulators of muscle mass. In July 2023, the Company announced that taldefgrobep received ODD from the European Commission for the treatment of SMA. Taldefgrobep previously received Fast-Track and ODD from the FDA.

Capital Position:

Cash, cash equivalents, marketable securities and restricted cash totaled approximately $495 million as of October 5, 2023, which included net proceeds of $242 million from completed public offering on October 5, 2023.

Third Quarter 2023 Financial Highlights:

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $95.5 million for the three months ended September 30, 2023, compared to $52.8 million for the three months ended September 30, 2022. The increase of $42.7 million was primarily due to increases in direct program spend for additional and advancing clinical trials, including late Phase 2/3 studies, and preclinical research programs in 2023, as compared to the same period in the prior year. Non-cash share-based compensation expense was $2.2 million for the three months ended September 30, 2023, a decrease of $7.5 million as compared to the same period in 2022. Non-cash share-based compensation expense was higher in the third quarter of 2022 primarily because expense allocated from Biohaven Pharmaceutical Holding Company Ltd.'s (the Former Parent[1]) equity plan, prior to the spin-off, was based on equity awards with higher grant date fair values, which was partially offset by increased personnel costs related to increased headcount in 2023.

General and Administrative (G&A) Expenses: General and administrative expenses were $15.0 million for the three months ended September 30, 2023, compared to $14.8 million for the three months ended September 30, 2022. The increase of $0.2 million was increased personnel costs in the third quarter of 2023 due to a majority of the personnel costs in three months ended September 30, 2022 being allocated to the Former Parent, offset by decreased non-cash share-based compensation costs. Non-cash share-based compensation expense was $2.3 million for the three months ended September 30, 2023, a decrease of $5.0 million as compared to the same period in 2022. Non-cash share-based compensation expense was higher in the third quarter of 2022 primarily because expense allocated from the Former Parent equity plan, prior to the spin-off, was based on equity awards with higher grant date fair values.

Other Income (Expense), Net: Other income (expense), net was a net income of $4.7 million for the three months ended September 30, 2023. The Company did not record any other income (expense) for the three months ended September 30, 2022. The increase of $4.7 million was primarily due to an increase in net investment income of $3.8 million and an increase of $1.2 million in other income related to our transition services provided to the Former Parent, which is largely non-recurring.

Net Loss: Biohaven reported a net loss for the three months ended September 30, 2023, of $102.6 million, or $1.50 per share, compared to $68.9 million, or $1.75 per share, for the same period in 2022. Non-GAAP adjusted net loss for the three months ended September 30, 2023 was $98.1 million, or $1.44 per share, compared to $49.2 million, or $1.25 per share for the same period in 2022. 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. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below. For periods prior to the Spin-Off, net loss per share and non-GAAP adjusted net loss per share were calculated based on the 39,375,944 common shares of Biohaven distributed to the Former Parent shareholders at the time of the distribution, including common shares issued in connection with the Former Parent share options that were settled on October 3, 2022 and common shares issued in connection with the Former Parent restricted share units that vested on October 3, 2022.  The same number of shares is being utilized for the calculation of basic and diluted earnings per share for all periods presented prior to the Spin-Off.

Non-GAAP Financial Measures
This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also 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 transaction-related cost incurred relating to the company's spin-off from Biohaven Pharmaceutical Holding Company Ltd., which are limited to a specific period of time and related to Biohaven Ltd. being established as a standalone public company. 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.
