Driving clinical, regulatory, and operational excellence across five innovative platforms focused on immunology, neuroscience, and oncology: Portfolio targeting large indications including obesity, epilepsy, bipolar disorder, depression, obsessive-compulsive disorder (OCD), migraine, pain, Alzheimer's disease, Parkinson's disease, multiple sclerosis, rheumatoid arthritis, and cancer. Also advancing potential novel treatments for rare autoimmune and inflammatory diseases, including myasthenia gravis, cardiomyopathy, spinal muscular atrophy (SMA) and IgA nephropathy. Pivotal clinical data milestones expected across three distinct programs: First-in-human Phase 1 study with BHV-1300 initiated in 1Q 2024. Preliminary immunoglobulin G (IgG) lowering data from the single ascending dose (SAD) portion of the study expected in late 1Q 2024/early 2Q 2024. The MAD portion of the study is being planned in a relevant patient population with the possibility of benefit from BHV-1300. Phase 3 database lock for interim efficacy analysis with troriluzole in OCD remains on schedule for 1Q 2024, with results expected in 2Q 2024. Phase 3 topline data in ongoing fully enrolled SMA study with taldefgrobep expected 2H 2024. Multiple trial initiations and Investigational New Drug (IND) filings projected over next three years present potential for continued growth and value creation. NEW HAVEN, Conn., Feb. 29, 2024 /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 fourth quarter and full year ended December 31, 2023, and provided a review of recent accomplishments and anticipated upcoming developments. Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "We embarked on a bold execution plan after completing our spin-off, re-emerging as a separate entity focused on immunology, neuroscience, and oncology. In just over a year's time, we made tremendous strides in progressing our programs, providing impressive and supportive pre-clinical and clinical outcomes for our key stakeholders, including patients, who may gain access to differentiated drugs for difficult to treat medical conditions. Today we are focused on delivering outcomes across five platforms spanning inflammation and immunology, ion channel modulation, myostatin inhibition, glutamate modulation, and oncology. In the year ahead, we expect to deliver potentially groundbreaking data across three distinct programs. In the near-term, we expect to report first-in-human Phase 1 IgG lowering data with our pan-IgG degrader, BHV-1300, with broad potential application. Given the profoundly deep and rapid reduction in IgG levels observed in non-human primate studies, unique ability to co-administer with Fc-containing biologics, ease of self-administration, and favorable toxicology profile observed to date, we are eagerly awaiting the proof-of-concept human data. We also plan to report OCD Phase 3 topline data in the second quarter of 2024 from an interim analysis with our glutamate modulating agent, troriluzole. There has been little to no innovation in advancing treatments for this disorder in decades and a win in this Phase 3 trial would be a substantial clinical success for the three million patients across the OCD community, many of whom are plagued by debilitating intrusive thoughts and compulsions. And finally, we're expecting Phase 3 topline data in the second half of the year with our anti-myostatin compound, taldefgrobep alfa, for patients with SMA. Dr. Coric continued, "Beyond data expectations, we are excited with the progress made across the balance of our portfolio, starting with our Kv7 ion channel activation program, where we have operationalized over 110 clinical trial sites in our focal epilepsy trials and are advancing development programs in generalized epilepsy, bipolar disorder, and major depressive disorder. Excitement is also mounting for the potential of taldefgrobep alfa in weight loss, a compound that we believe will maintain and grow muscle mass as a means of helping to address the global obesity crisis. We also expect to deliver additional trial initiations across our broad IgG degrader program targeting both large indications and rare autoimmune/inflammatory diseases, TYK2/JAK1 inhibition in neuroinflammatory disorders, TRPM3 antagonism initially in migraine and neuropathic pain, and with our antibody drug conjugates program in an array of oncology indications. We are passionate about helping patients in need, and excited about our portfolio, the skilled drug development team we have in place, and the vast opportunity in the year ahead." Full Year and Recent Business Highlights Ion Channel Platform - Milestones and Next Steps: Kv7 Ion Channel Activation: Epilepsy & Neuropsychiatric Indications BHV-7000, the lead asset from the Kv7 platform, is a selective activator of Kv7.2/Kv7.3, a key ion channel involved in regulation of neuronal signaling and hyperexcitability. Reported BHV-7000 Phase 1 study results: In December 2023, the Company reported full results from the BHV-7000 Phase 1 SAD and multiple ascending dose (MAD) studies examining doses up to 120mg daily, demonstrating BHV-7000 was well-tolerated at all doses studied without the typical central nervous system (CNS) adverse effects associated with other anti-seizure medications (ASMs), such as somnolence and cognitive/mood disturbances. Results were consistent with previously reported preclinical data demonstrating BHV-7000's lack of GABAA receptor activation and lack of adverse impacts on neurobehavior in preclinical testing. Demonstrated CNS target engagement: In December 2023, the Company reported additional data from a Phase 1 electroencephalogram (EEG) biomarker study, where BHV-7000 demonstrated dose-dependent target engagement in the brain as shown by dose-dependent effects on EEG spectral power across all frequency bands. While changes in spectral power were observed across all frequency bands with BHV-7000, the minimal impact on slower frequencies (i.e., delta) is consistent with the low incidence of CNS adverse events observed in the BHV-7000 Phase 1 SAD/MAD studies. EEG delta activity is associated with somnolence, an undesirable CNS adverse event commonly reported with other ASMs. Developed once-daily formulation: In September 2023, the Company announced it had formulated an extended release, once-a-day tablet designed to achieve target therapeutic concentrations (25mg, 50mg and 75mg). This dosing approach with a Kv7 activator will allow for assessment of distinct target concentrations over a wide range, above and below projected efficacious EC50 drug concentrations, not previously feasible with drugs in this class. Sites operationalized: In January 2024, the Company completed its End-of-Phase 2 meeting with FDA to advance to Phase 3 trials and announced that more than 110 global clinical sites have been selected in the ongoing focal epilepsy trial, with enrollment planned for 1Q 2024. Upcoming trial initiations: The Company expects to initiate Phase 2/3 programs in focal epilepsy in 1Q 2024 and in generalized epilepsy in 2Q 2024; the Company also expects to initiate a Phase 2 study in major depressive disorder and a Phase 2/3 study in bipolar disorder in 1H 2024. TRPM3 Ion Channel Antagonism: Migraine & Neuropathic Pain BHV-2100 is an oral, selective TRPM3 antagonist offering a novel, non-addictive treatment for migraine and neuropathic pain. Phase 1 study data supports evaluation in acute migraine: In January 2024, the Company detailed preliminary pharmacokinetic (PK) and safety data from an ongoing Phase 1 study; in the study, BHV-2100 was rapidly absorbed, achieved 90% inhibitory concentrations within one hour, and was well tolerated at projected therapeutic concentrations Upcoming trial initiations: The Company expects to initiate a BHV-2100 Phase 2 study in acute migraine in 2H 2024 and conduct a POC study for neuropathic pain in 2H 2024. Inflammation and Immunology Platform - Milestones and Next Steps: Targeted Extracellular Protein Degradation: Molecular Degraders of Extracellular Proteins (MoDEs™) uniquely harness the hepatic ASGPR receptor for efficient and safe removal of circulating pathogenic targets; BHV-1300, is an IgG degrader. Reported on progress with BHV-1300: The Company has demonstrated the effect of a single dose of BHV-1300 in lowering IgG in nonhuman primates (NHPs), previously reporting over 75-80% reduction of IgG levels from baseline in three days. These data compare favorably to other IgG targeting agents, such as the FcRn inhibitor efgartigimod, where reduction of IgG levels, following a single dose, was shown to be approximately 50% in 5-7 days. In September 2023, the Company announced positive multiple dose, pharmacodynamic (PD) data from a NHP study with BHV-1300 demonstrating 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. Demonstrated potential for same-day, co-administration with Fc-containing biologics: In January 2024, the Company presented new NHP data demonstrating that Biohaven's IgG degrader technology allows for co-administration with Fc-containing biologics; PK of Humira® was unaltered after being dosed 12 hours after BHV-1300 administration. Reported preclinical pharmacodynamic data with single dose of BHV-1310: In January 2024, the Company showed that a next generation and optimized IgG degrader, BHV-1310, allowed for much deeper 90% reductions in IgG after a single dose. Given the deep and rapid reductions observed, the Company believes BHV-1310 may have potential application in acute settings. Unveiled plans for BHV-1600: next-generation, selective degrader targeting β1-AR autoantibodies: In January 2024, the Company reported preclinical data demonstrating degradation of anti-β-1AR antibody in mice. The Company expects to file an IND application and initiate a first-in-human Phase 1 study in 2H 2024. BHV-1600 will initially be evaluated in patients with dilated cardiomyopathy. Near-term data expected: The Phase 1 SAD study examining BHV-1300 in healthy subjects was initiated in 1Q 2024 and the Company expects preliminary results in late 1Q 2024/early 2Q 2024. The FDA indicated that the MAD assessment of BHV-1300 should be performed in a relevant patient population. Upon completion of the SAD study, Biohaven is planning the MAD portion of the study in a relevant patient population with the possibility of benefit from BHV-1300. Upcoming trial initiations: A total of 4 INDs are expected for the degrader program in 2024. TYK2/JAK1 Inhibition: BHV-8000 is an oral, brain-penetrant, selective TYK2/JAK1 inhibitor with broad potential for neuroinflammatory and neurodegenerative disorders. Successfully completed single ascending dose cohorts; advanced multiple ascending dose cohorts in ongoing Phase 1 study of TYK2/JAK1 inhibitor, BHV-8000: In January 2024, the Company provided a program update for the ongoing Phase 1 study designed to evaluate the safety, tolerability, PK and PD of single and multiple ascending doses of BHV-8000 in healthy volunteers. The SAD cohorts have now completed dosing (10, 20 and 30 mg); in the MAD cohorts, the Company completed up to the 20 mg dose. 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. Upcoming trial initiations: The Company expects to initiate a Phase 2 study in multiple sclerosis in 2H 2024, a Phase 2a study in prevention of amyloid therapy induced ARIA in 2H 2024, and Phase 2/3 studies in early Parkinson's disease and early Alzheimer's disease in 2H 2024. Myostatin Platform - Milestones and Next Steps: Taldefgrobep alfa is a novel myostatin inhibitor optimized to target myostatin and associated signaling pathways of muscle growth. Taldefgrobep alpha also has promise as a potential treatment for obesity and, in preclinical models as well as preliminary healthy human studies, has demonstrated meaningful reductions in fat mass, the primary pathogenic tissue in obesity, while increasing lean mass. Biohaven is also studying taldefgrobep in a global Phase 3 study in Spinal Muscular Atrophy to enhance muscle mass and function in patients treated with standard-of-care gene therapy treatments. Preclinical data demonstrated taldefgrobep alfa reduces fat and improves lean mass: In October 2023, the Company presented 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. Completed enrollment in pivotal Phase 3 study 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. In July 2023, the Company announced that taldefgrobep received orphan drug designation (ODD) from the European Commission for the treatment of SMA. Taldefgrobep previously received Fast-Track and ODD from the FDA. Topline data expected: The Company expects to announce Phase 3 topline data from the ongoing SMA study in 2H 2024. Upcoming trial initiation: The Company expects to initiate a Phase 2 study in patients with obesity in 2Q 2024. Glutamate Modulation Platform - Milestones and Next Steps: Troriluzole is a novel glutamate modulator currently being evaluated in Phase 3 trials for obsessive-compulsive disorder as an adjunctive therapy in patients with an inadequate response to existing standard-of-care treatment. Topline data from interim analysis in OCD expected in 2Q 2024: In January 2024, the Company shared an update on the ongoing Phase 3 trial in OCD. The Company remains on schedule for a database lock in 1Q 2024, with an interim efficacy analysis expected in 2Q 2024. Biohaven has also continued to have constructive dialogue with the FDA regarding its SCA development program and potential future data analyses to address regulatory concerns in the previously issued refuse-to-file decision on its NDA application for SCA3. Biohaven will provide further updates on the SCA development program as warranted by any continued positive progress from the outcome of future regulatory interactions on this topic. Next-Generation ADC Platform - Milestones and Next Steps: Biohaven's antibody drug conjugate (ADC) technology is focused on novel conjugation chemistry with the potential to be superior to the current industry standard maleimide and lipophilic click chemistry. BHV-1510 is a TROP2 directed ADC, with a highly differentiated efficacy and safety profile providing an opportunity to broaden therapeutic margin, increase time on treatment, and improve efficacy; BHV-1500 demonstrated superior efficacy to Adcetris® (brentuximab vedotin) and improved survival in a mouse xenograft model. Upcoming trial initiations: The Company completed its regulatory interactions to begin first-in-human studies with BHV-1510 (TROP2 directed ADC) and expects to initiate a Phase 1 trial in 2Q 2024. The company also expects to submit an IND for BHV-1500 (next-generation brentuximab ADC) in 2H 2024. Corporate Updates: 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.

Fourth Quarter 2023 Financial Highlights: Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $134.8 million for the three months ended December 31, 2023, compared to $137.0 million for the three months ended December 31, 2022. The decrease of $2.2 million was primarily due to decreased non-cash share-based compensation expense during the three months ended December 31, 2023, and $5.2 million of one-time employee costs related to the Pfizer acquisition of Biohaven Pharmaceutical Holding Company Ltd. (the Former Parent) in the fourth quarter of 2022. This was partially offset by increased costs related to advancing additional clinical development program activities, including late Phase 2/3 studies and preclinical research programs, and recognition of one-time expenses of a $10.0 million cash payment and a $21.8 million non-cash issuance of common shares to acquire rights related to our agreement with Highlightll in the three months ended December 31, 2023, as compared to the same period in the prior year. Non-cash share-based compensation expense was $9.1 million for the three months ended December 31, 2023, a decrease of $60.3 million as compared to the same period in 2022. The decrease was primarily due to $61.7 million of expense allocated from the Former Parent recognized in connection with the settlement of outstanding Former Parent stock options and restricted stock units (RSUs) upon the effectiveness of the Former Parent's distribution to holders of all outstanding common shares of Biohaven and the spin-off of Biohaven from the Former Parent (the Separation) in the fourth quarter of 2022. General and Administrative (G&A) Expenses: General and administrative expenses were $18.9 million for the three months ended December 31, 2023, compared to $76.4 million for the three months ended December 31, 2022. The decrease of $57.5 million was primarily due to decreased non-cash share-based compensation expense during the three months ended December 31, 2023, and $8.2 million of transaction-related expenses and $8.9 million of one-time employee costs related to the Pfizer acquisition of the Former Parent in the fourth quarter of 2022. Non-cash share-based compensation expense was $6.8 million for the three months ended December 31, 2023, a decrease of $39.5 million as compared to the same period in 2022. The decrease was primarily due to $39.7 million of expense allocated from the Former Parent recognized in connection with the settlement of outstanding Former Parent stock options and RSUs upon the effectiveness of the Separation in the fourth quarter of 2022. Other Income (Expense), Net: Other income (expense), net was a net income of $7.7 million for the three months ended December 31, 2023, compared to a net expense of $1.8 million for the three months ended December 31, 2022. The increase of $9.6 million was primarily due to a $10.0 million impairment loss recognized during the fourth quarter of 2022 on our Artizan Series A-2 Preferred Stock Investment. Net Loss: Biohaven reported a net loss for the three months ended December 31, 2023, of $144.8 million, or $1.81 per share, compared to $201.1 million, or $3.32 per share, for the same period in 2022. Non-GAAP adjusted net loss for the three months ended December 31, 2023 was $128.9 million, or $1.61 per share, compared to $77.3 million, or $1.27 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 and transaction-related costs incurred relating to the Company's spin-off from Biohaven Pharmaceutical Holding Company Ltd. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below.

Other Income (Expense), Net: Other income (expense), net was a net income of $26.5 million for the year ended December 31, 2023, compared to a net expense of $1.9 million for the three months ended December 31, 2022. The increase of $28.4 million was primarily due to increased net investment income of $14.5 million and increased service revenue from the Transition Service Agreement we entered into with the Former Parent of $5.2 million in 2023, as compared to the same period in the prior year, as well as a $10.0 million impairment loss recognized during the fourth quarter of 2022 on our Artizan Series A-2 Preferred Stock Investment. Net Loss: The Company reported a net loss attributable to common shareholders for the year ended December 31, 2023 of $408.2 million, or $5.73 per share, compared to $570.3 million, or $12.75 per share for the same period in 2022. Non-GAAP adjusted net loss for the year ended December 31, 2023 was $379.4 million, or $5.33 per share, compared to $362.7 million, or $8.11 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 and transaction-related costs incurred relating to the Company's spin-off from Biohaven Pharmaceutical Holding Company Ltd. 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 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 costs 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.

Biohaven reported full results from the BHV-7000 Phase 1 study examining doses up to 120 mg daily, demonstrating BHV-7000 was well-tolerated at all doses studied without the typical central nervous system (CNS) adverse effects associated with other anti-seizure medications (ASMs), such as somnolence and cognitive/mood disturbances. In a Phase 1 electroencephalogram (EEG) biomarker study, BHV-7000 demonstrated dose-dependent target engagement in the brain as measured by changes in EEG spectral power across all brain regions. Additional poster presentations at the American Epilepsy Society Annual Meeting will include: BHV-7000 preclinical data, health-related quality of life in patients with focal epilepsy, and functional impairments in patients with KCNQ2‐associated developmental and epileptic encephalopathy (KCNQ2-DEE). NEW HAVEN, Conn., Dec. 1, 2023 /PRNewswire/ -- Biohaven Ltd. (NYSE: BHVN) announced today that it is presenting expanded EEG and safety data for BHV-7000 at the 2023 American Epilepsy Society (AES) Annual Meeting, taking place December 1-5, 2023, in Orlando, Florida. The presentations include results from the BHV-7000 Phase 1 EEG biomarker study and additional BHV-7000 safety and tolerability data from Phase 1 single ascending dose (SAD) / multiple ascending dose (MAD) studies. Additional posters showcase BHV-7000's preclinical data, findings from a systematic literature review on health-related quality of life (HRQoL) in patients with focal epilepsy, and results from a cross-sectional survey assessing functional impairments in patients with KCNQ2-DEE. Jason Lerner, M.D., Medical Director and Epilepsy Clinical Lead at Biohaven, commented "Selective Kv7 activators are one of the most exciting new drug targets for the treatment of epilepsy, and BHV-7000 has shown a favorable and differentiated profile in preliminary Phase 1 studies to date. We are pleased to see favorable safety and tolerability with BHV-7000 dosed up to 120 mg daily for 15 days, without the CNS adverse effects typically associated with other ASMs, such as somnolence. Together with the preclinical data showing BHV-7000 is a selective Kv7.2/7.3 channel opener lacking GABAA activation and the results from our Phase 1 EEG study confirming target engagement, we are excited to advance BHV-7000 into late-stage development in epilepsy patients." Dr. Lerner added, "The robust BHV-7000 data presentations at the AES meeting underscore Biohaven's progress and commitment to developing novel, efficacious and well-tolerated therapies for people living with epilepsy." In addition, both the systematic literature review and parental survey illustrated the importance of Health-Related Quality of Life issues among patients with focal epilepsy and developmental manifestations of KCNQ2-DEE that are relevant to parents, such as communication, eating abilities, and motor impairments. Presentation Highlights: Poster 2.510: Novel, Selective Kv7.2/7.3 Potassium Channel Activator, BHV-7000, Demonstrates Dose-Dependent Pharmacodynamic Effects on EEG Parameters in Healthy Adults In this Phase 1 study, pharmacodynamic activity of BHV-7000 in the brain of healthy adults was demonstrated by dose-dependent increases in EEG spectral power. Unlike prior reports where EEG effects of a Kv7.2/7.3 activator showed the greatest power increase in the delta frequency band (Biondi et al. 2022), the highest spectral power increases with BHV-7000 were seen in alpha, beta, and gamma frequency bands. While changes in spectral power were observed across all frequency bands with BHV-7000, the minimal impact on slower frequencies (i.e., delta) is consistent with the low incidence of CNS adverse events, in particular somnolence, seen in the BHV-7000 Phase 1 SAD/MAD studies. EEG delta activity is associated with somnolence, an undesirable CNS adverse event often seen with other ASMs. Poster 3.265: A First in Human Phase 1 Study Evaluating the Safety and Tolerability of BHV-7000, a Novel, Selective Kv7.2/7.3 Potassium Channel Activator, in Healthy Adults BHV-7000 was safe and well-tolerated at single doses up to 100 mg and multiple doses up to 120 mg daily for 15 days No serious adverse events or severe treatment emergent adverse events were reported Adverse events typically associated with other ASMs, such as somnolence and cognitive/mood disturbances, were not reported Poster 2.249: Characterization of BHV-7000: A Novel Kv7.2/7.3 Activator for the Treatment of Seizures BHV-7000 is a potent activator of Kv7.2/7.3 channels, impacting both deactivation kinetics and voltage dependence of activation BHV-7000 requires the Kv7.2 W236 residue for channel activity No significant activation of the GABAA receptor with BHV-7000 BHV-7000 is potent in the maximal electroshock seizure (MES) test without impact on neurobehavior or motor (rotorod) behavior Poster 1.487: Determinants of Health-Related Quality of Life of Patients with Focal Epilepsy: A Systematic Literature Review This systematic literature review identified multiple factors associated with lower HRQoL in patients with focal epilepsy Depression and anxiety were among the most significant and frequent determinants of HRQoL change Other relevant and frequent determinants of HRQoL change included cognition, ASM adverse events, seizure freedom, and employment A comprehensive understanding of the modifiable determinants of HRQoL is relevant to patient health and well-being and can inform clinical practice and observational/interventional studies Poster 2.451: Functional Impairments in Patients with KCNQ2-DEE: Associations Among Key Clinical Features Data obtained from a cross-sectional survey (2018-2020) of parents of children aged ≥2 years with KCNQ2-DEE was analyzed Among individuals with KCNQ2-DEE, there is a hierarchy of impairments wherein communication is the most sensitive domain and is often affected in isolation from others Gross and fine motor skill impairments tend to be correlated Hand use impairment is closely correlated with multiple other functional impairments Full posters will be available on the Posters and Presentations page at: .

About BHV-7000 BHV-7000, the lead asset from Biohaven's Kv7 platform, is a novel and selective activator of Kv7.2/Kv7.3, a key ion channel involved in neuronal signaling and in regulating the hyperexcitable state, that Biohaven is developing for the treatment of epilepsy and mood disorders. BHV-7000 was rationally developed as a potent activator of heteromeric Kv7.2/7.3 potassium channels, the molecular substrate that underlies the M-current (IKM). BHV-7000 is highly differentiated from ezogabine (known as retigabine in Europe), a Kv7 activator that was previously approved for adjunctive treatment of partial-onset seizures in adults. In comparison with ezogabine, BHV-7000 belongs to a significantly different structural class and differentiates from ezogabine in key properties, including pharmacology, plasma stability and stability to photooxidation. In addition, BHV-7000 does not exhibit GABAA receptor positive allosteric molecular activity as seen with ezogabine and similar compounds, which may contribute to the poor tolerability of ezogabine. This lack of GABAA receptor activity potentially gives BHV-7000 a wide therapeutic window which, based on dose-dependent clinical responses seen in other ASM clinical trials, should translate to improved efficacy without the typical dose dependent side effect profile often seen in patients receiving ezogabine and other anti-seizure medications.

Pictured: MRI scans of a brain/iStock, Nur Ceren Demir Results from the Phase IIb X-TOLE study showed that Xenon Pharmaceuticals’ investigational potassium channel opener XEN1101 could safely reduce seizure burden in adults with focal epilepsy, the company announced Monday. The data, published Monday in the journal JAMA Neurology, came from a randomized, double-blinded, parallel-group and placebo-controlled mid-stage study of 325 patients suffering from focal-onset seizures—the most common type of epileptic seizures. XEN1101 treatment led to a dose-dependent drop in seizure burden and the effect was significantly better than placebo at all dose levels. At 25 mg, seizure frequency dropped by a median of 52.8% after eight weeks of treatment, while the 20-mg dose reduced seizures by 46.4% versus baseline. Even at the lowest dose level of 10 mg, XEN1101 led to a significant 33.2% decrease in seizure frequency from baseline compared with placebo, which was only associated with an 18.2% reduction. In terms of safety, X-TOLE found Xenon’s candidate to be generally well-tolerated. The observed treatment-emergent adverse events were broadly in line with other drugs in the same class. None of the toxicities led to death. “XEN1101 continues to demonstrate its efficacy through sustained seizure reduction and a compelling product pro once-daily dosing with food and no titration required,” Xenon CEO Ian Mortimer said in a statement. With these latest data, Xenon will “continue to advance” the candidate through its Phase III development in the X-TOLE2 and X-TOLE3 studies in focal-onset seizures as well as the X-ACKT trial in primary generalized tonic-clonic seizures, Mortimer said. XEN1101 is a selective small molecule opener of the Kv7.2/Kv7.3 voltage-gated potassium channels, dysfunctions in which have been linked to seizures. By enhancing the opening of these channels, XEN1101 could help prevent seizures. Also targeting Kv7.2/Kv7.3 voltage-gated potassium channels is pharma company Biohaven. Like XEN-1101, its candidate BHV-7000 is a selective activator of the channel, which in turn facilitates neuronal signaling and prevents seizures. Last month, Biohaven posted positive electroencephalogram biomarker data for the candidate at projected therapeutic concentrations, which could point to its potential as an antiseizure treatment. With these promising biomarker data, Biohaven is pushing through with Phase III development for BHV-7000 in focal epilepsy, which is set to begin before the year ends. Biohaven is an established leader in the neurology and migraine space. In May 2022, its predecessor company Biohaven Pharmaceuticals was acquired by Pfizer for more than $11 billion. Following the buyout, Biohaven launched anew on October 2022 with its renewed focus on the Kv7 ion channel. Tristan Manalac is an independent science writer based in Metro Manila, Philippines.
