Effect of Verdiperstat on Microglial Activation in Well-characterized MSA Patients

This study will comprise of two phases, an observational phase and a treatment phase.
In the observational phase the specific aims are: 1. To determine the presence and regional distribution of microglial activation, as assessed by 18F-PBR06 PET, in subjects with MSA as compared to healthy controls, at baseline and at 6-9 months' follow-up.
2. To assess the relationship between microglial activation and clinical progression at baseline and follow-up.
In the treatment phase the specific aims of the study are:
The specific aims of the study are:
To assess whether verdiperstat (BHV-3241) reduces 18F-PBR06 PET signal, and thus microglial activation and inflammation, in well-characterized MSA patients.
To assess the relationship between PET changes and clinical progression at baseline and follow-up in patients treated with verdiperstat.
To assess the relationship between PET changes and volumetric brain MRI at baseline and follow-up in patients treated with verdiperstat.
Currently there is no known disease modifying therapy for MSA. Recently, the drug verdiperstat (BHV-3241) has appeared in the investigational arena specifically for the indication of Multiple System Atrophy. Verdiperstat (BHV-3241) is currently being used in a phase 3 active drug trial at Massachusetts Hospital. Verdiperstat (BHV-3241) is known to target Myeloperoxidase, an enzyme implicated in neuroinflammation, a major driver in disease pathogenesis. Our previous study (IRB protocol #2016P002373) demonstrated that applying TSPO (translator protein) PET imaging enabled us to track changes in neuroinflammation and thus provide a viable biomarker for disease progression.
In this pilot study, the investigators aim to assess the effect of an investigational drug, verdiperstat (BHV-3241) on microglial activation in MSA patients using [F-18]PBR06 and to link it with clinical and morphometric MRI brain changes following treatment.

Paul ; Penney, Ellen B. ; Sadri‐Vakili, Ghazaleh ; Fernandez‐Cerado, Cara ; Lei, Dan ; Diesta, Cid Czarina E. ; Motlagh, Negin Jalali ; Tanzi, Rudolph E. ; Zhang, Can ; Ang, Mark C. ; Qureshi, Irfan A. ; Chen, John W. ; Bragg, D. Cristopher ; Petrozziello, Tiziana ; Monsanto, Ranee Zara B. ; Murcar, Micaela G.

ABSTRACT:

Aims:

Although the genetic locus of X‐linked dystonia parkinsonism (XDP), a neurodegenerative disease endemic in the Philippines, is well‐characterized, the exact mechanisms leading to neuronal loss are not yet fully understood. Recently, we demonstrated an increase in myeloperoxidase (MPO) levels in XDP postmortem prefrontal cortex (PFC), suggesting a role for inflammation in XDP pathogenesis. Therefore, we hypothesized that inhibiting MPO could provide a therapeutic strategy for XDP.

Methods:

MPO activity was measured by using an MPO‐activatable fluorescent agent (MAFA) in human postmortem PFC. Reactive oxygen species (ROS) and MPO activity were measured in XDP‐derived fibroblasts and SH‐SY5Y cells following MPO inhibition.

Results:

MPO activity was significantly increased in XDP PFC. Additionally, treatment of cell lines with postmortem XDP PFC resulted in a significant increase in ROS levels. To determine whether increases in MPO activity caused increases in ROS, MPO content was immunodepleted from XDP PFC, which resulted in a significant decrease in ROS in SH‐SY5Y cells. Consistently, the treatment with verdiperstat, a potent and selective MPO inhibitor, significantly decreased ROS in both XDP‐derived fibroblasts and XDP PFC‐treated SH‐SY5Y cells.

Conclusions:

Collectively, our results suggest that MPO inhibition mitigates oxidative stress and may provide a novel therapeutic strategy for XDP treatment.

Prediction of the liver safety profile of a first-in-class myeloperoxidase inhibitor using quantitative systems toxicology modeling

Article

Author: Gebremichael, Yeshi ; Wirtz, Victoria ; Woodhead, Jeffrey L. ; Howell, Brett A. ; Woodhead, Jeffrey L ; Macwan, Joyce ; Howell, Brett A ; Bertz, Richard ; Qureshi, Irfan A ; Qureshi, Irfan A.

The novel myeloperoxidase inhibitor verdiperstat was developed as a treatment for neuroinflammatory and neurodegenerative diseases. During development, a computational prediction of verdiperstat liver safety was performed using DILIsym v8A, a quantitative systems toxicology (QST) model of liver safety.A physiologically-based pharmacokinetic (PBPK) model of verdiperstat was constructed in GastroPlus 9.8, and outputs for liver and plasma time courses of verdiperstat were input into DILIsym. In vitro experiments measured the likelihood that verdiperstat would inhibit mitochondrial function, inhibit bile acid transporters, and generate reactive oxygen species (ROS); these results were used as inputs into DILIsym, with two alternate sets of parameters used in order to fully explore the sensitivity of model predictions. Verdiperstat dosing protocols up to 600 mg BID were simulated for up to 48 weeks using a simulated population (SimPops) in DILIsym.Verdiperstat was predicted to be safe, with only very rare, mild liver enzyme increases as a potential possibility in highly sensitive individuals. Subsequent Phase 3 clinical trials found that ALT elevations in the verdiperstat treatment group were generally similar to those in the placebo group. This validates the DILIsym simulation results and demonstrates the power of QST modelling to predict the liver safety profile of novel therapeutics.

Abstract:

Introduction/Aims:

Expanded access (EA) is a Food and Drug Administration‐regulated pathway to provide access to investigational products (IPs) to individuals with serious diseases who are ineligible for clinical trials. The aim of this report is to share the design and operations of a multicenter, multidrug EA program for amyotrophic lateral sclerosis (ALS) across nine US centers.

Methods:

A central coordination center was established to design and conduct the program. Templated documents and processes were developed to streamline study design, regulatory submissions, and clinical operations across protocols. The program included three protocols and provided access to IPs that were being tested in respective regimens of the HEALEY ALS Platform Trial (verdiperstat, CNM‐Au8, and pridopidine). Clinical and safety data were collected in all EA protocols (EAPs). The program cohorts comprised participants who were not eligible for the platform trial, including participants at advanced stages of disease progression and with long disease duration.

Results:

A total of 85 participants were screened across the 3 EAPs from July 2021 to September 2022. The screen failure rate was 3.5%. Enrollment for the regimens of the platform trial was completed as planned and results informed the duration of the corresponding EAP. The verdiperstat EAP was concluded in December 2022. Mean duration of participation in the verdiperstat EAP was 5.8 ± 4.1 months. The CNM‐Au8 and pridopidine EAPs are ongoing.

Discussion:

Multicenter EAPs conducted in parallel to randomized clinical trials for ALS can successfully enroll participants who do not qualify for clinical trials.

The HEALEY Platform Trial: Quick Failures and New Hope for ALS

iStock/ higyou Launched in 2020 to more quickly bring to market an effective medicine for amyotrophic lateral sclerosis, the HEALEY Platform Trial has generated disappointing results for many but also continuing programs from Clene and Prilenia. Clinical wins have been few and far between for the HEALEY ALS Platform Trial . A heterogeneous patient population and delays have posed challenges, with several biotechs discontinuing programs based on underwhelming results. But optimism persists among the trial’s leaders and early participants, with two companies, Clene Nanomedicine and Prilenia Therapeutics, moving their investigational amyotrophic lateral sclerosis (ALS) treatments forward. The first seed for an ALS platform trial was planted when Massachusetts General Hospital’s Merit Cudkowicz read an article on master platform trials by former FDA Principal Deputy Commissioner Janet Woodcock. “I read that one and thought it might be appropriate for ALS,” Cudkowicz told BioSpace . Then, along came Sean Healey, a prominent American businessman who had recently been diagnosed with ALS, with an attractive opportunity. He said, “I might not save myself from this illness, but I want to make a difference. Give me a proposal,” Cudkowicz recalled. So she and her team worked around the clock, ultimately pitching the platform trial, and “[Healey] loved it. He just got it right away, that it was efficient and good for patients.” Healey, in partnership with his global asset management firm, Affiliated Managers Group (AMG), donated $40 million to launch the Sean M. Healey & AMG Center for ALS at Mass General, and set in motion a new chapter in ALS research. Cudkowicz serves as the center’s director. Biopharma quickly jumped on board with the platform trial, with dozens of companies—in addition to Clene and Prilenia, UCB, Biohaven Pharmaceutical and Seelos Therapeutics—vying to be a part of it. Fast forward four years and none of these drugs has hit the trial’s primary endpoints. But Clene CEO Rob Etherington said that doesn’t reflect a failure of the study itself. The HEALEY trial was designed to “fast fail” assets that don’t have utility, he explained, “and it worked in that respect, for a few of the regimens.” Indeed, Cudkowicz noted that Biohaven, which ultimately opted against moving forward with the program, also viewed the trial as a success because “they got a quick answer, a clear answer.” Biohaven did not respond to BioSpace ’s request for comment. But perhaps most notably, Clene and Prilenia showed positive data on secondary endpoints that prompted those companies to progress their candidates, Cudkowicz said. “So, I really actually view that as a success.” The First Five To select the initial round of participants in the trial, Cudkowicz and her team decided to host a competition. She noted that many aspiring platform trials seemed to be stuck at the funding stage and believed a call for proposals would speed up the process. The prize: entry into the Healey ALS Platform Trial, where some costs for the first companies would be covered. The team received 30 proposals from all over the world. Cudkowicz and her colleagues assessed each therapy based on clinical potential, mechanism of action, and diversity of approach. “We did want to pick drugs with different targets for the first five,” Cudkowicz said. Finally, they selected five programs. UBC’s zilucoplan inhibits complement component 5, the dysregulation of which is implicated in ALS, while Biohaven’s verdiperstat blocks the enzyme that reduces oxidative stress and neuroinflammation. Clene’s CNM-Au8, by contrast, is an oral, liquid suspension of gold nanocrystals designed to improve the survival, function, and communication of nerve cells. Prilenia’s pridopidine is also a neuroprotective agent, and Implicit Bioscience’s IC14 is an anti-CD14 monoclonal antibody devised to regulate the pathogenic inflammatory responses to infection and injury. Of these, Clene and Prilenia fared the best. Although both companies’ assets missed their primary endpoints, positive biomarker data and benefit to a subgroup of patients in Prilenia’s case supported moving the programs forward. With Prilenia’s candidate, a subgroup of patients with early-stage ALS who were rapidly declining had “substantially less decline” in ALS Functional Rating Scale-Revised (ALSFRS-R) total score compared to placebo. The company has stated plans to launch a Phase III trial. Meanwhile, Clene has a briefing book in front of the FDA based on HEALEY data and additional biomarker results gleaned from the RESCUE-ALS trial and survival data from ongoing compassionate use protocols. While the agency originally said the data were insufficient to support a new drug application, Clene has since submitted more information, including mechanistic and ALS-specific biomarkers and data on a super-responder group, which Etherington said is now under review. Clene also gathered promising survival and biomarker data from its arm of the HEALEY study. Treatment with CNM-Au8 for up to 133 weeks decreased the risk of death by 49% compared to PRO-ACT database–matched placebo, according to Clene, while also reducing levels of neurofilament light chain (NfL), which is gaining ground as a predictor of clinical outcomes in neurodegenerative diseases. “Without the survival secondary endpoint win and the exploratory endpoint win and the neurofilament biomarker win that HEALEY gave Clene, we’d be in a very different position today,” Etherington said. “We certainly wouldn’t have a briefing book under consideration at the FDA without HEALEY.” The other companies have either shut down their programs or are still determining next steps. Implicit never moved forward to the design phase. UCB’s arm of the trial was stopped early after an interim analysis demonstrated futility, according to a Massachusetts General press release . Meanwhile, Biohaven’s verdiperstat failed to statistically differentiate from placebo, and the drug is no longer listed in the company’s pipeline . Seelos joined after Implicit departed and got mixed results. The company stated in a March press release that while its drug trehalose failed to meet statistical significance in the primary and secondary endpoint in the HEALEY study, it showed a “potential signal of efficacy” in a subgroup of patients not taking Amylyx’s Relyvrio, which was given to some trial participants after its approval in September 2022 . And the HEALEY trial marches on. In July 2022, Calico Life Sciences signed on to test ABBV-CLS-7262, and Denali Therapeutics announced its participation with DNL343 in December of the same year. Data from these arms of the trial are expected in early 2025. Another company, Australian outfit PharmAust, recently committed to studying its drug monepantel, and Cudkowicz said talks are ongoing with several more companies. Cudkowicz said that no matter what the result of the various arms, “you can learn a lot about [ALS].” Patient- and Business-Centric Platform trials are a fairly new phenomenon, and Cudkowicz shared that she learned a lot from the DIAN Alzheimer’s trial at Washington University. The model offers myriad benefits, including efficiency. While a clinical trial typically takes more than a year to get off the ground, the HEALEY study is a perpetual trial , meaning a new drug regimen can be added in just 30 days. It’s also patient-centric. The use of a shared placebo between all regimens means that more patients receive a potentially efficacious drug. This also means companies have to recruit fewer patients. The fact that some of their costs were covered was a significant benefit for the smaller companies in the HEALEY trial. Prilenia, for example, had six employees at the time it applied to join the trial. “The good news was they paid for the drug, so we didn’t have to raise money for [that],” Hayden told BioSpace . The infrastructure build and support were also partially funded by several foundations, Cudkowicz said. “I’m grateful. Without HEALEY, we would never have done this trial,” Hayden said. “We didn’t have the money.” The companies involved also have access to elite experience in the ALS space. Cudkowicz is widely considered to be the dean of ALS drug development, and both Etherington and Hayden referenced the gravitas associated with the HEALEY trial, which includes 75 research sites. “The advantage of HEALEY is undeniably the fact that you have an easy network of top expert centers . . . so you’re really able to access the top centers in the United States of America,” Etherington told BioSpace . “That is a tremendous advantage for young startup companies to have access to and to be involved with.” Etherington added that acceptance into the trial gave CNM-Au8 credibility “because it really was a testament of others’ stamp of approval that are well respected in the space.” Growing Pains Still, a complex structure with so many moving parts is bound to take time to perfect. Etherington noted that every drug is unique, and “a platform study does not enable an individual drug and its unique aspects of mechanism or side effects or administration to actually make any changes” to the trial’s protocol. For example, each cohort in the HEALEY trial has run for six months. For CNM-Au8, this was too short of a window to prove efficacy, Etherington said. “To have everybody come in and have to fit the framework with no exceptions, that’s a challenge.” Notably, Cudkowicz shared that the team is currently considering amending the protocol based on learnings from the first five regimens. “This includes possibly longer duration of follow up on the randomized controlled trial period to address the possibility that some medications need more time to achieve biological and clinical effects,” she said. Cudkowicz added that a voice app developed by Aural Analytics and used in the first four regimens is “turning out to be a very good digital biomarker. We also did home spirometry (a measure of lung function), which looks pretty much just as good as in clinic.” Another challenge for a trial with multiple centers across the U.S., Etherington said, was an initial delay in receiving data from every center, though Clene is now in possession of the final datasets from the HEALEY trial. Because every regimen starts at a different time, they all finish at different times, slowing down the rate at which results are available. For a company conducting a single study, “all hands are on deck,” Etherington said. By contrast, in a platform trial, “we have to be more ecumenical. We have to share, as it were, the load and the timeline, and we need to recognize that the company’s individual interests need to be subjugated, to some degree, to the whole of the platform study.” Hayden agreed, saying that the HEALEY team was sometimes “overwhelmed” with running what amounts to eight trials, and that there sometimes is “a little frustration in terms of the speed of response, the ability to get statistical analysis done. All of that can be slower than we would like.” Cudkowicz acknowledged that the trial has faced challenges in this regard. “Since the idea of platform trials is efficiency and speed, we want all parts of it to be efficient,” she said. “Some of the structural, operational things that slow down trials in general are still in play in platform trials [and] how trials are started up at academic institutions is still too slow, in my opinion. We have some new initiatives to improve this dramatically for the next several new regimens,” she said in an email. Cudkowicz added that interest in the trial overwhelmed the capacity of some of the trial sites. “There’s high interest in it from the companies, from the patients, but now we’ve gotta do it even faster.” A heterogeneous patient population was another challenge, Hayden said. “The study included essentially everybody with ALS, and that was maybe . . . both positive and negative. The positive was that this gave hope to everybody.” However, ALS has a “very heterogeneous population.” The HEALEY trial included patients with definite, probable and possible ALS, as well as those more than three years out from diagnosis. “We were concerned about that right in the beginning because we knew that all the trials that had been successful in ALS had a different population” that included patients with only definite and probable ALS, and a shorter disease duration, Hayden said. Prilenia ultimately prespecified that it wanted to also study pridopidine in patients with early-stage ALS, diagnosed less than 18 months before the trial’s start, and HEALEY investigators were able to recruit from such a population for the arm of the trial testing the drug. And while pridopidine failed the primary endpoint in the full analysis set, in patients with early ALS, “what we saw is that we had a very wonderful positive effect,” Hayden said. “We delayed progression for the first time ever seen in an ALS trial at eight weeks.”

(NYSE: BHVN) ("Biohaven" or the "Company"), a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies for people with debilitating neurological and neuropsychiatric diseases, including ultra-rare disorders, today reported financial results for the first quarter ended March 31, 2023, and provided a review of recent accomplishments and anticipated upcoming milestones. Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "We have set forth ambitious goals for the balance of 2023, as we continue advancing what we believe is one of the most innovative and exciting neuroscience platform in development. We were energized by the preliminary safety, tolerability and pharmacokinetic data we reported from our SAD/MAD Phase 1 study of Kv7.2/Kv7.3 activator BHV-7000 earlier in the quarter, supported by the preponderance of preclinical efficacy data generated to date with BHV-7000 demonstrating potent anti-seizure efficacy, concentration-dependent hyperpolarization of the resting membrane potential, meaningful increases in action potential threshold, and encouragingly low GABAA activity. We also look forward to unlocking Kv7 platform expansion opportunities across a spectrum of indications with high unmet medical need." Dr Coric continued, "With our glutamate platform, we look to gain clarity on the regulatory path forward for SCA and expect to complete enrollment in our Phase 3 OCD program in 2023, which we believe are two critically important milestones given the dearth of approved therapies for these distinct patient populations. Regarding our myostatin platform, we continue to activate sites and drive enrollment in our ongoing Phase 3 SMA study. With our recently acquired TYK2/JAK1 platform, we remain focused on starting Phase 1 studies in 2023 and exploring BHV-8000's potential to address an array of immune-mediated brain disorders. And finally, we look forward to submitting IND applications across three separate programs, including BHV-7010, a next-gen Kv7 activator targeting epilepsy and mood disorders, BHV-2011, a TRPM3 inhibitor targeting chronic pain, and BHV-1300, our IgG degrader, following the report of robust preclinical data earlier in the year. We remain as committed as ever to driving data-driven, efficient results for patients and the shareholders who support our continued work, and look forward to executing and delivering continued value in the year ahead." First Quarter 2023 and Recent Business Highlights Acquired BHV-8000, a brain-penetrant inhibitor of TYK2/JAK1, from Highlightll - As previously reported, in March 2023, the Company acquired exclusive rights (excluding China) to a novel, oral, first-in-class, brain-penetrant, dual inhibitor of TYK2/JAK1 offering wide therapeutic index with TYK2 inhibition and high selectivity for JAK1 inhibition without the severely limiting adverse class effects of JAK2/JAK3 inhibitors. The Company expects to commence Phase 1 development in 2023, exploring its potential to address immune-mediated brain disorders. Delivered oral and poster presentations demonstrating preclinical efficacy and initial Phase 1 safety and tolerability of BHV-7000 on ASENT 2023 virtual platform - In March 2023, the Company presented data at the 2023 American Society for Experimental Neurotherapeutics Annual Meeting (ASENT 2023) demonstrating that activating Kv7.2/7.3 with BHV-7000, a structurally and pharmacologically distinct compound from ezogabine, produced concentration-dependent hyperpolarization of the resting membrane potential, potentiated meaningful increases in action potential threshold, exhibited significantly lower GABAA activity than ezogabine, and delivered potent anti-seizure efficacy in the maximal electroshock seizure (MES) model, without negatively impacting neurobehavior. The Company also presented data from the Phase 1 SAD/MAD clinical trial, demonstrating BHV-7000 was well-tolerated at single doses up to 100 mg and multiple doses up to 40 mg per day for 15 days. Most adverse events were mild and resolved spontaneously, and there were no serious or severe adverse events or dose-limiting toxicities reported. In BHV-7000 treated subjects in the MAD study, CNS-related adverse events typically associated with other anti-seizure medications were not reported. Taldefgrobep Alfa Granted Fast Track Designation and Orphan Drug Designation - As previously reported, Taldefgrobep alfa, an anti-myostatin adnectin in development for SMA, was granted Fast Track designation and Orphan Drug designation by the U.S. Food and Drug Administration (FDA) in February 2023, and December 2022, respectively. Phase 3 studies are ongoing; the Company expects to enroll approximately 180 patients in this randomized, double-blind, placebo-controlled global trial. Reported preclinical data with extracellular target degrader platform technology (MoDE™), a pan-IgG degrader - As previously reported, in January 2023, the Company evaluated the effect of a single dose of IgG degrader, BHV-1300, in cynomolgus monkeys. The Company reported 75% reduction of IgG levels from baseline and noted the observation occurred in three days; the data in this pre-clinical study compares favorably to standard of care therapy efgartigimod, where reduction of IgG levels with efgartigimod was observed to be 50% and had taken 5-7 days. The Company expects BHV-1300 will be ready for IND submission in the second half of 2023. Reported preclinical data with second MoDE in bispecific platform targeting IgA Nephropathy - As previously reported, in January 2023, the Company reported preclinical data with a second MoDE targeting galactose deficient IgA (Gd-IgA), which is believed to play a pathogenic role in IgA Nephropathy. Specific removal of pathogenic Gd-IgA with preservation of normal IgA potentially permits disease remission without incurring an infection risk. The Company shared preliminary data demonstrating the chimeric antibody-ASGPR ligand conjugate specifically mediated endocytosis of Gd-IgA, as opposed to normal IgA, in an endocytosis assay with HepG2 cells. Leadership team expanded with key appointment - In April 2023, Biohaven announced the appointment of Nick Kozauer, M.D. as SVP of Clinical Development and Regulatory Strategy following his tenure as Director of the Division of Neurology 2 in the Office of New Drugs of the FDA. Dr. Kozauer had supervised and reviewed the approval of over 15 marketed drugs during his tenure at the FDA. Upcoming Expected Milestones: Biohaven is progressing its product candidates through clinical programs in a number of common and rare disorders. The Company expects to reach significant pipeline milestones in the coming periods. Biohaven expects to: Initiate EEG study with BHV-7000 in the first half of 2023: Following Phase 1 study completion, Biohaven expects to initiate pivotal trials in patients with epilepsy and patients with bipolar disorder in the second half of 2023. Submit IND with BHV-7010 in epilepsy and mood disorders: The Company expects to submit an IND with next-generation Kv7 activator BHV-7010 in epilepsy in the second half of 2023. Submit IND with BHV-2100 in chronic pain: The Company expects to submit an IND with BHV-2100, a TRPM3 antagonist in the Company's ion channel platform targeting a pain disorder in the second half of 2023. Submit IND with BHV-1300: The Company expects to submit an IND with pan-IgG degrader BHV-1300 in the second half of 2023. Commence Phase 1 studies with BHV-8000: The Company expects to commence Phase 1 studies with BHV-8000, an oral, brain-penetrant, dual TYK2/JAK1 inhibitor for immune-mediated brain disorders in 2023. Complete enrollment in Phase 3 study of troriluzole in OCD in 2023: Two Phase 3 randomized, double-blind, placebo-controlled studies are expected to enroll up to 700 patients (in each trial) across nearly 200 global study sites. The Company anticipates completing enrollment in year-end 2023. Provide an update on troriluzole in SCA: The Company intends to interact with the FDA and/or European Medicines Agency in the first half of 2023 on next steps. Continue advancing Phase 3 clinical studies of taldefgrobep alfa in SMA: The Company expects to enroll approximately 180 patients in the study through patient enrollment in up to 60 clinical sites. Continue advancements across multiple neuroscience and immunoscience indications: The Company's preclinical pipeline includes molecular degraders of extracellular proteins, CD38 targeting antibody recruiting molecules (ARMs), TRP channels, and other undisclosed targets, including those with disease-modifying potential. Capital Position: Cash, cash equivalents and marketable securities as of March 31, 2023 was $392.0 million, including $4.0 million of restricted cash, and excluding $61.5 million of cash payable to Biohaven Pharmaceutical Holding Company Ltd. (the "Former Parent"), compared to $467.9 million, including $2.5 million of restricted cash, and excluding $35.2 million of cash payable to the Former Parent, as of December 31, 20221. First Quarter 2023 Financial Highlights: Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $63.5 million for the three months ended March 31, 2023, compared to $70.1 million for the three months ended March 31, 2022. The decrease of $6.6 million was primarily due to a decrease of $14.7 million in personnel-related costs including non-cash share-based compensation costs, and a decrease in expenses for verdiperstat, BHV-2100 and BHV-1200, partially offset by an increase in expenses for our clinical programs for Kv7 (BHV-7000 and 7010), troriluzole and BHV-2000. The decrease in personnel-related costs is due to non-cash share-based compensation expense for the first quarter of 2022 being allocated from the Former Parent equity plan based on equity awards with higher grant date fair values, which was partially offset by increased personnel costs related to an increase in headcount for our discovery operations. Non-cash share-based compensation expense was $2.2 million for the three months ended March 31, 2023, a decrease of $22.3 million as compared to the same period in 2022. General and Administrative (G&A) Expenses: G&A expenses, including non-cash share-based compensation costs, were $14.3 million for the three months ended March 31, 2023, compared to $19.7 million for the three months ended March 31, 2022. The decrease of $5.4 million was primarily due to decreased non-cash share-based compensation costs. This was partially offset by increased personnel costs in the first quarter of 2023 compared to the same period in 2022, due to a majority of the personnel costs in the first quarter of 2022 being allocated to the Former Parent. Non-cash share-based compensation expense was $1.5 million for the three months ended March 31, 2023, a decrease of $14.1 million as compared to the same period in 2022. The decrease in non-cash share-based compensation expense is due to the first quarter of 2022 expense being allocated from the Former Parent equity plan based on equity awards with higher grant date fair values. Other Income (Expense), Net: Other income (expense), net was a net income of $8.2 million for the three months ended March 31, 2023, compared to net expense of $4.0 thousand for the three months ended March 31, 2022. The increase of $8.2 million was primarily due to an increase in net investment income and an increase of $3.9 million in other income related to our transition services provided to our Former Parent, which is largely non-recurring. Net Loss: Biohaven reported a net loss for the three months ended March 31, 2023, of $70.5 million, or $1.03 per share, compared to $97.0 million, or $2.46 per share, for the same period in 2022. Non-GAAP adjusted net loss for the three months ended March 31, 2023 was $66.7 million, or $0.98 per share, compared to $56.9 million, or $1.45 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 Biohaven's spin-off from the Former Parent on October 3, 2022 (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. 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 Ltd. launched post-closing of the Biohaven Pharmaceutical Holding Company Ltd. sale to Pfizer on October 4, 2022, and completed a public offering of 28,750,000 Biohaven Ltd. common shares at a price of $10.50 per share on October 25, 2022, with a total initial capitalization and net cash proceeds from offering of approximately $541 million, and no debt. Advancing multiple late-stage clinical programs including innovative drug candidates targeting Kv7 modulation for epilepsy and neuropsychiatric disorders, glutamate modulation in Obsessive-Compulsive Disorder (OCD) and spinocerebellar ataxia (SCA), and myostatin in spinal muscular atrophy (SMA). Key industry executives added to leadership team, including: Bruce Car, Ph.D. as Chief Scientific Officer; Irfan Qureshi, M.D. as Chief Medical Officer, and Tanya Fischer, M.D., Ph.D. as Chief Development Officer and Head of Translational Medicine. NEW HAVEN, Conn., Nov. 9, 2022 /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 for people with debilitating neurological and neuropsychiatric diseases, including rare disorders, today reported financial results for the third quarter ended September 30, 2022, and provided a review of recent accomplishments and anticipated upcoming milestones. The reported financial results present, on a historical basis, the combined assets, liabilities, expenses and cash flows directly attributable to the Company, which have been prepared from Biohaven Pharmaceutical Holding Company Ltd., the former parent, consolidated financial statements and accounting records, and are presented on a stand-alone basis as if the operations had been conducted independently from the former parent. Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "Just weeks after launching in October as a new publicly traded company and separate independent entity as part of the merger agreement with Pfizer, we continued to advance our late stage clinical development programs and substantially enhanced our resources by raising gross proceeds of approximately $301.9 million in a public financing that drew support from a breadth of longstanding and new Biohaven investors. We are well positioned with an outstanding drug development team, a deep late-stage pipeline and a strong capital position to favorably position us to accelerate development across our portfolio." Dr. Coric continued, "Our Kv7 platform, with its vast potential to address epilepsy and neuropsychiatric indications, is being prioritized by the team with the goal of at least one Phase 2/3 study start in 2023. We also continue to make progress with our Phase 3 study evaluating taldefgrobep alfa in patients with spinal muscular atrophy, as well as with our Phase 3 study evaluating troriluzole in patients with OCD. Finally, our discovery efforts remain a key pillar of our pipeline formation strategy; with IND-enabling studies underway across several programs, we expect to provide updates on programs like TRPM3, a potential breakthrough, non-opioid treatment option for pain, and other earlier stage protein degrader programs in the coming months and years. Our unwavering commitment to patients continues propelling us forward and we cannot wait to deliver additional therapeutic breakthrough medicines to drive outcomes for patients, shareholders and employees." Third Quarter and Recent Business Highlights: Company launch - On October 3, 2022, Biohaven Ltd. began operating as a separate independent entity in connection with the merger agreement entered into with Pfizer Inc. in May 2022. As of October 4, 2022, Biohaven Ltd. commenced regular way trading under the symbol "BHVN" on the New York Stock Exchange as an independent, publicly traded company focused on delivering innovative life-changing treatments for neurological and neuropsychiatric diseases, including rare disorders, and leveraging its proven drug development capabilities and proprietary technology platforms to advance a pipeline of best-in-class therapies. The Company, led by Vlad Coric, M.D. as Chairman and Chief Executive Officer, launched with approximately $257.8 million in cash and no debt. Public offering - On October 25, 2022, the Company closed its previously announced underwritten public offering of 28,750,000 of its common shares, which includes the full exercise of the underwriters' option to purchase 3,750,000 additional shares, at the public offering price of $10.50 per share. The gross proceeds raised in the offering, before deducting underwriting discounts and estimated expenses of the offering payable by the Company, were approximately $301.9 million. As of November 7, 2022, we had 68,160,979 common shares, without par value per share, outstanding. Advanced Phase 1 studies for BHV-7000 - As previously reported, in the second quarter of 2022, the Company's Clinical Trial Application for BHV-7000 was approved by Health Canada, and the Company subsequently began clinical development. BHV-7000, the lead asset from the Kv7 platform, is an activator of Kv7.2/Kv7.3, a key ion channel involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy. Advanced development of extracellular target degrader platform technology (MoDEs™) for therapies across a variety of diseases including neuroscience, immunology and oncology - In October, Biohaven announced advancements in the development of its MoDE extracellular target degrader platform technology licensed from Yale University for various disease indications, including, but not limited to, neurological disorders, cancer, infectious and autoimmune diseases. Biohaven made further innovations in this ground-breaking technology with new patent applications covering additional targets and functionality. Operationalized fully-equipped Biohaven Cambridge laboratory - In October, the Company expanded its footprint to include new laboratory space in Cambridge, Massachusetts. Commenced enrollment in Phase 3 SMA study - In July, the Company commenced enrollment in a Phase 3 clinical trial assessing the efficacy and safety of taldefgrobep alfa in SMA. Taldefgrobep targets myostatin, a natural protein that limits skeletal muscle growth, through two mechanisms: lowering myostatin directly and blocking key downstream signaling mechanisms. The Company expects to enroll approximately 180 patients in this randomized, double-blind, placebo-controlled global trial. Global Coalition for Adaptive Research (GCAR) commenced enrollment in Glioblastoma Adaptive Global Innovative Learning Environment (GBM Agile) Phase 2-3 adaptive platform trial for patients with glioblastoma - In July, GCAR announced the activation of Biohaven's troriluzole in GBM AGILE, a patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent glioblastoma (GBM). GBM AGILE is an international, innovative platform trial designed to more rapidly identify and confirm effective therapies for patients with glioblastoma through response adaptive randomization. The new interventions are opening first at Henry Ford Health Cancer in Detroit under Henry Ford site Principal Investigator Dr. Tom Mikkelsen and will subsequently open at more than 40 trial sites across the United States with additional global sites to follow. Upcoming Milestones: Biohaven is progressing its product candidates through clinical programs in a number of common and rare disorders. The Company expects to reach significant pipeline milestones in the coming periods. Biohaven expects to: Complete Phase 1 studies of BHV-7000 in the first half of 2023: If the Phase 1 studies are successfully completed, Biohaven expects to initiate at least one pivotal trial in patients with epilepsy in the second half of 2023. Complete enrollment in Phase 3 study of troriluzole in OCD in 2023: Two Phase 3 randomized, double-blind, placebo-controlled studies are expected to enroll approximately 1,300 patients across nearly 200 global study sites. The Company anticipates completing enrollment in 2023. Provide an update on troriluzole in SCA: The Company had previously reported top-line results from a Phase 3 clinical trial evaluating the efficacy and safety of its investigational therapy, troriluzole, in patients with SCA in May of 2022. While the primary endpoint, change from baseline to Week 48 on the modified functional Scale for the Assessment and Rating of Ataxia did not reach statistical significance in the overall SCA population, as there was less than expected disease progression over the course of the study, post hoc analysis of efficacy measures by genotype suggested a treatment effect in patients with the SCA Type 3 (SCA3) genotype, which represents the most common form of SCA and accounted for 41 percent of the study population. The Company intends to interact with the FDA and/or EMA in the first half of 2023. We have not yet decided on the format of such a regulatory interaction but we could seek advice through various formal or informal interactions with regulatory agencies or we could choose to submit a New Drug Application (NDA) if we believe that is warranted from the results of our ongoing post-hoc analyses. Continue advancing Phase 3 clinical studies of taldefgrobep alfa in SMA: The Company expects to enroll approximately 180 patients in the study. Continue advancing early discovery portfolio across multiple neuroscience and immunoscience indications: The Company's preclinical pipeline includes molecular degraders of extracellular proteins, CD38 targeting antibody recruiting molecules (ARMs), TRP channels, TDP-43 targeting small molecules, and other undisclosed targets, including those with disease-modifying potential. Continue pursuing formulation development work with BHVN-5500 for use in combination studies with Kv7 platform: The Company is developing BHV-5500 (lanicemine), a low-trapping NMDA receptor antagonist. One potential target indication includes Complex Regional Pain Syndrome. Other disorders of interest include post-herpetic neuralgia and diabetic peripheral neuralgia. Current work is focused on formulation development. Capital Position: Cash as of September 30, 2022 was $50.7 million, excluding $0.8 million of restricted cash, compared to $76.1 million as of December 31, 2021. On October 3, 2022, in connection with the closing of the acquisition of Biohaven Pharmaceutical Holding Company Ltd. by Pfizer, Biohaven Ltd. launched with a cash balance of approximately $257.8 million. On October 25, 2022, the Company closed its previously announced public offering, which resulted in net proceeds to the Company of approximately $282.8 million. Third Quarter 2022 Financial Highlights: Research and Development ("R&D") Expenses: R&D expenses, including non-cash share-based compensation costs, were $52.8 million for the three months ended September 30, 2022, compared to $47.0 million for the three months ended September 30, 2021. The increase of $5.9 million was primarily due to increased expenses relating to our clinical programs partially offset by decreases in our program expenses for verdiperstat. Non-cash share-based compensation expense was $9.7 million for the three months ended September 30, 2022, a decrease of $0.5 million as compared to the same period in 2021. General and Administrative ("G&A") Expenses: G&A expenses, including non-cash share-based compensation costs, were $14.8 million for the three months ended September 30, 2022, compared to $8.5 million for the three months ended September 30, 2021. The increase of $6.3 million was primarily due to increased expenses related to accounting, legal and other professional fees associated with the Pfizer acquisition and spin-off of Biohaven Ltd. as an independent, publicly traded company. Non-cash share-based compensation expense was $7.3 million for the three months ended September 30, 2022, an increase of $2.1 million as compared to the same period in 2021. Net Loss: Biohaven reported a net loss for the three months ended September 30, 2022, of $68.9 million, or $1.75 per share, compared to $54.4 million, or $1.38 per share, for the same period in 2021. Non-GAAP adjusted net loss for the three months ended September 30, 2022 was $49.2 million, or $1.25 per share, compared to $39.0 million, or $0.99 per share for the same period in 2021. 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 gains or losses from equity method investment. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below. Net loss per share and Non-GAAP adjusted net loss per share were calculated based on the 39,368,042 shares of Biohaven Ltd. common stock distributed to Biohaven Pharmaceutical Holding Company Ltd. shareholders at the time of the Distribution, including common shares issued in connection with Biohaven Pharmaceutical Holding Company Ltd. stock options that were exercised on October 3, 2022 and common shares issued in connection with Biohaven Pharmaceutical Holding Company Ltd. restricted stock 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, adjusted to exclude the items below. 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, when viewed in conjunction with GAAP results, provides investors with a more meaningful understanding of ongoing operating performance. These measures exclude (i) non-cash share-based compensation, which is substantially dependent on changes in the market price of common shares, (ii) gains or losses from equity method investment, which are non-cash and based on the financial results and valuation of another company that we did not manage or control, and (iii) 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. Biohaven believes the presentation of these non-GAAP financial measures provides useful information to management and investors regarding Biohaven's results of operations. When GAAP financial measures are viewed in conjunction with these non-GAAP financial measures, investors are provided with a more meaningful understanding of Biohaven's ongoing operating performance and are better able to compare 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 press release.
