Biohaven Pharmaceuticals Reports Third Quarter 2019 Financial Results And Recent Business Developments

NEW HAVEN, Conn., Nov. 1, 2019 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN, the "Company"), a clinical-stage biopharmaceutical company with a portfolio of innovative, late-stage product candidates targeting neurological and neuropsychiatric diseases, today reported financial results for the quarter ended September 30, 2019, and provided a review of recent accomplishments and anticipated milestones.

Vlad Coric, M.D., CEO of Biohaven commented, "The Biohaven team continues to deliver on the R&D front with 5 pivotal trials expected to read out over the next few months. Additionally, we are eagerly preparing for a potential drug launch of rimegepant in the first quarter of 2020."  Dr. Coric added, "We have completed hiring our commercial leadership team, and we are building a world class sales organization that can fully realize the potential of our entire pipeline—CGRP antagonism in migraine, glutamate modulation in neuropsychiatric disorders and myeloperoxidase inhibition in rare neurologic disorders. Our goal is to create value for patients and shareholders while maintaining an efficient and high performing culture."

Third Quarter and Recent Business Highlights

Calcitonin Gene-Related Peptide (CGRP) Antagonist Programs:

• Announced acceptance by the FDA of the NDAs for the Zydis^® ODT and tablet formulations of rimegepant; mid-cycle communication received from FDA with no specific issues identified; expected PDUFA date for rimegepant Zydis^® ODT is the first quarter of 2020 – In September 2019, Biohaven presented at the 2019 Annual Wells Fargo Healthcare Conference, which included a discussion of pipeline progress, an update on the NDA filing acceptances and PDUFA date for rimegepant Zydis^® ODT and updates on other commercial launch activities.
   
  In October 2019, the Company presented an update to investors on its broad pipeline of late stage product candidates, which included updates for the mid-cycle communication received from the FDA regarding the rimegepant new drug application review. All FDA comments are preliminary and do not reflect a final decision on the review. At the time of the mid-cycle communication:
• No major safety concerns were identified; the Company does not anticipate the need for a Risk Evaluation and Mitigation Strategy (REMS).
• There were no plans for an Advisory Committee meeting.
• There were no specific issues requiring input from the Company.
   
• Completed enrollment of pivotal Phase 3 trial of rimegepant for the preventive treatment of migraine – In August, the Company announced that it completed enrollment in its pivotal Phase 3 preventative treatment of migraine trial with rimegepant and expects topline data at the end of the fourth quarter of 2019 or early first quarter of 2020. Given rimegepant's high affinity for the CGRP receptor and its relatively long half-life, the Company believes that rimegepant may possess unique "dual-therapy" action with a potential ability to provide acute treatment of migraine attacks and preventive effects. To the Company's knowledge, rimegepant is currently the only small molecule CGRP antagonist being developed for both the acute and preventive indications in the treatment of migraine.
   
• Completed enrollment in pivotal Phase 2/3 trial of vazegepant for the acute treatment of migraine – In September, the Company announced it completed enrollment in its Phase 2/3 trial of intranasally administered vazegepant for the acute treatment of migraine. The Phase 2/3 trial is designed to measure efficacy on regulatory endpoints for acute treatment of migraine – pain freedom and freedom from the most bothersome migraine-associated symptom at 2 hours post-dose – for vazegepant across three doses (5 mg, 10 mg and 20 mg) versus placebo. The trial will also study other clinical measures considered critically important to people living with migraine, such as pain relief and the return to normal functioning. Top line data is expected in the fourth quarter of 2019.
   
• Presented expanded data from long term clinical study demonstrating clinically important benefits after oral treatment of rimegepant on migraine-specific disability and quality of life at the International Headache Conference – In September, the Company presented expanded data and post-hoc analyses from its long term clinical study (BHV3000-201) demonstrating clinically important benefits of rimegepant on migraine-specific disability and quality of life in late breaking oral and poster sessions at the International Headache Conference in Dublin, Ireland.
• Acute treatment of migraine with rimegepant, an oral CGRP receptor antagonist, decreased disability by approximately 41% as measured by the Migraine Disability Assessment (MIDAS) questionnaire.
• Rimegepant treatment also demonstrated clinically significant improvements in daily functioning and health-related quality of life as measured by the Migraine-Specific Quality of Life Scale (MSQoL).
• Rimegepant dosed up to once daily for the acute treatment of migraine reduced lost productivity time by approximately 50% over the one-year treatment period.

Glutamate Program:

• Completed enrollment in pivotal Phase 3 trial of troriluzole for the treatment of GAD – In October, the Company announced that it completed enrollment in its pivotal Phase 3 clinical trial assessing troriluzole in GAD and expects topline data at the end of the fourth quarter of 2019 or early first quarter of 2020. This multicenter, randomized, placebo-controlled, trial enrolled over 880 patients in less than nine months. The primary outcome measure in this 8-week GAD trial with troriluzole is the change in a patient's score on the Hamilton Anxiety Rating Scale (HAM-A), a scale designed to assess the severity and type of symptoms in patients with GAD. The HAM-A is a widely used and validated scale that has served as the primary outcome measure to obtain approval in GAD both in the United States and globally. The trial will also assess the safety, tolerability and pharmacokinetics of troriluzole. 

Myeloperoxidase Program:

• Verdiperstat selected for platform trial collaboration at Massachusetts General Hospital's Healey & AMG Center for ALS – In September, the Company announced that its myeloperoxidase (MPO) inhibitor, verdiperstat, was selected as an investigational therapy in the first Amyotrophic Lateral Sclerosis (ALS) platform trial, a program designed by the Sean M. Healey & AMG Center for ALS at Mass General Hospital to help accelerate a path to new and effective ALS treatments. An independent advisory council selected verdiperstat for inclusion in the platform based on a thorough scientific and clinical review. In contrast with traditional trials that typically evaluate only one drug at a time, platform trials create an infrastructure for the ongoing study of multiple investigational drugs in parallel using specialized statistical methods to help maximize resources and efficiency. 
   
• Enrolled first patient in phase 3 clinical trial of verdiperstat for the treatment of multiple system atrophy – In July, the Company announced that it enrolled the first patient in a Phase 3 clinical trial to evaluate the efficacy and safety of verdiperstat in subjects with MSA. The study will enroll subjects with MSA diagnosed using consensus clinical criteria and include both subtypes of MSA, MSA-Parkinsonism (MSA-P) and MSA-Cerebellar (MSA-C). Researchers will evaluate the efficacy of verdiperstat, compared to placebo, as measured by a change from baseline in a modified version of the Unified MSA Rating Scale (UMSARS) at Week 48.

Upcoming Milestones
Biohaven is progressing drug candidates for a number of common and rare disorders through clinical and preclinical programs. The Company expects to reach significant pipeline milestones with its CGRP receptor antagonists, glutamate modulators and myeloperoxidase inhibitor in the coming quarters.

The Company expects to:

• Continue to advance the rimegepant Zydis^® ODT (orally dissolving tablet) program towards commercialization for the acute treatment of migraine.
• Report Phase 2/3 topline efficacy and safety results for vazegepant in acute treatment of migraine in fourth quarter of 2019.
• Complete enrollment in Phase 2/3 trial of troriluzole in Alzheimer's disease and conduct futility analysis in the fourth quarter of 2019.
• Report Phase 2/3 topline of troriluzole in GAD at the end of the fourth quarter of 2019 or early first quarter of 2020.
• Report Phase 3 topline data for rimegepant in preventive treatment of migraine at the end of the fourth quarter of 2019 or early first quarter of 2020.
• Complete enrollment in Phase 2/3 trial with troriluzole in Obsessive-compulsive Disorder by the end of 2019.
• Complete enrollment in Phase 3 trial of troriluzole in Spinocerebellar Ataxia in the first quarter of 2020.
• Continue enrolling patients in Phase 2 proof of concept trial evaluating the safety and efficacy of rimegepant in patients with treatment refractory trigeminal neuralgia.
• Continue enrolling patients in Phase 3 clinical trial for the treatment of MSA, a rare, rapidly progressive and fatal neuroinflammatory disease with no cure or effective treatments.
• Conduct ongoing non-clinical studies defined under the scientific research agreement with University of Connecticut to support the advancement of UC1MT, a therapeutic antibody targeting extracellular metallothionein.

Third Quarter Financial Results

Cash Position: Cash as of September 30, 2019, was $416.6 million, compared to $465.7 million as of June 30, 2019. The decrease in cash during the period of $49.1 million primarily reflects cash used in operations of $70.1 million to prepare for commercial launch expected in early 2020 and to advance our broad pipeline of late stage product candidates, partially offset by $21.2 million in net proceeds from the partial exercise of the underwriters option to purchase additional common shares in July 2019 from the June 2019 public offering of common shares.

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $61.7 million for the three months ended September 30, 2019, compared to $47.4 million for the three months ended September 30, 2018. The increase of $14.3 million was primarily due to increased expenses due to later stage trials in our CGRP platform and troriluzole program of $12.8 million and $4.7 million, respectively, and an increase in personnel related costs of $4.4 million. The increase in R&D expenses was partially offset by a $7.1 million one-time license payment to AstraZeneca in the third quarter of 2018.  Included in R&D expense for the three months ended September 30, 2019 is $7.5 million in costs related to process validation batches of rimegepant to support our expected commercial launch in the first quarter of 2020.

The increase in personnel-related costs, including non-cash share-based compensation, was a result of additional options issued and hiring additional personnel related to the anticipated commercial launch of rimegepant. Our headcount, in R&D, increased to 59 as of September 30, 2019, compared to 34 as of September 30, 2018.  Non-cash share-based compensation expense was $3.6 million for the three months ended September 30, 2019, an increase of $1.9 million as compared to the same period in 2018. 

General and Administrative (G&A) Expenses:  G&A expenses, including non-cash share-based compensation costs, were $28.8 million for the three months ended September 30, 2019, compared to $7.6 million for the three months ended September 30, 2018. The increase of $21.2 million was primarily due to increases in spending to prepare for commercial launch expected in early 2020, and personnel-related costs, including non-cash share-based compensation, due to the hiring of additional personnel primarily to prepare for commercialization of our product candidates, increases in professional fees supporting ongoing business operations, and additional fees to comply with the requirements of being a public company. Our headcount, in G&A activities, increased to 119 as of September 30, 2019, compared to 23 as of September 30, 2018.  Non-cash share-based compensation expense, included in personnel-related costs, was $6.3 million for the three months ended September 30, 2019, an increase of $4.4 million as compared to the same period in 2018.

Net Loss:  The Company reported a net loss attributable to common shareholders for the three months ended September 30, 2019 of $106.2 million, or $2.04 per share, compared to $61.4 million, or $1.53 per share for the same period in 2018.
