Biohaven Pharmaceuticals Reports Fourth Quarter And Full Year 2017 Financial And Business Results
NEW HAVEN, Conn., March 6, 2018 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN), a clinical-stage biopharmaceutical company with a portfolio of innovative, late-stage product candidates targeting neurological diseases, including rare disorders, today reported financial results for the fourth quarter and year ended December 31, 2017 and provided a review of recent accomplishments and anticipated upcoming milestones.
"2017 was an exciting year for Biohaven in which we completed a very successful IPO and advanced multiple drug candidates that we believe have the potential to be first-in-class or best-in-class across our two main technology platforms, making particularly rapid clinical progress with rimegepant, our oral CGRP receptor antagonist for the acute treatment of migraine," said Vlad Coric, M.D, Chief Executive Officer of Biohaven. "We have started 2018 with the same strong momentum as we prepare for important data announcements, drive toward key FDA filings, and continue to build our organization to support our expanded development pipeline and the eventual commercialization of approved products to help patients with severe neurological disorders."
Full Year and Recent Business Highlights
CGRP Receptor Antagonist Platform - Milestones and Next Steps
- Enrollment complete in two pivotal Phase 3 clinical trials of rimegepant - In November 2017, the Company completed enrollment in the second of two pivotal Phase 3 trials to evaluate the safety and efficacy of orally-dosed rimegepant, a small molecule, new chemical entity (NCE) for the acute treatment of migraine. Topline results from both trials are expected in the first quarter of 2018. Together, the two pivotal trials enrolled approximately 3,000 subjects, which is expected to support a robust assessment of the efficacy of rimegepant in the acute treatment of migraine as required by the U.S. Food and Drug Administration (FDA) for registration.
- Long-term safety study underway - Biohaven continues to evaluate the long-term safety of rimegepant in a third trial. To date, more than 1,000 patients are enrolled in this trial, and the Company expects that enrollment will be complete by the end of the first half of 2018.
- Entered into license agreement and initiated Phase 3 clinical trial using rimegepant orally dissolving tablets - In January 2018, the Company entered into an exclusive worldwide license agreement with Catalent U.K. Swindon Zydis Limited, a subsidiary of Catalent, Inc. (Catalent) to provide Catalent's Zydis® orally dissolving tablet (ODT) fast-dissolving formulation for the development of rimegepant and an exclusive agreement for the use of the Zydis® ODT formulation technology with small molecule CGRP receptor antagonists. In February 2018, a bioequivalence study was conducted to compare this new ODT formulation to the tablet in current clinical development and provided evidence of equivalence. A third Phase 3 efficacy study with rimegepant commenced in February 2018, and the study is expected to complete in the fourth quarter of 2018.
- FDA agreement on initial pediatric study plan (iPSP) for rimegepant - In November, the Company received agreement from the FDA on the initial pediatric study plan (iPSP) for orally-dosed rimegepant. Agreement on an iPSP is one of the regulatory requirements that must be met prior to submitting a new drug application (NDA).
- Continued progress for BHV-3500 toward IND submission and Phase 1 clinical trial in 2018 -- The Company remains on track to submit an investigational new drug application (IND) in first half of 2018 for BHV-3500, a third-generation CGRP receptor antagonist, for the acute treatment and prevention of migraine, and expects to conduct a Phase 1 clinical trial in the second half of 2018 to assess safety, tolerability and pharmacokinetics of BHV-3500 in healthy volunteers.
Glutamate Modulation Platform - Milestones and Next Steps
- Positive results from bioequivalence study of sublingual BHV-0223 Zydis® orally dissolving tablet - In January 2018, the Company announced positive results from its bioequivalence study with BHV-0223, an innovative sublingual formulation of riluzole. Topline results confirmed that sublingual BHV-0223 (40 mg) achieves bioequivalent exposures relative to Rilutek (50 mg). In the study, 138 healthy volunteers were administered BHV-0223 and Rilutek under fasted conditions. In the pre-specified primary analysis, BHV-0223 achieved area-under-the-curve and peak exposures of approximately 90% and 113%, respectively, compared to those generated by generic riluzole. According to previously received regulatory feedback from the FDA, the Section 505(b)(2) pathway is acceptable and, beyond this study, no additional efficacy or toxicology studies will be necessary for the submission of an NDA.
- First patient dosed in clinical trial for trigriluzole in Obsessive-Compulsive Disorder (OCD)
-- In October 2017, the FDA informed the Company that it may proceed with a Phase 2/3 clinical trial assessing the efficacy and safety of trigriluzole in patients with OCD, and Biohaven commenced dosing in the trial in December 2017. Trigriluzole is a novel third-generation prodrug glutamate modulator that has been observed to have a favorable safety and tolerability profile in clinical trials. Exposure data from recent clinical experience with trigriluzole in spinocerebellar ataxia (SCA) has helped inform the dosing of trigriluzole in the trial.
- Extension study of trigriluzole in patients with SCA -- Following top-line results of trigriluzole in patients with SCA, Biohaven is continuing a long-term (48-week) extension study. In dialogue with the FDA on the further development of trigriluzole in ataxias, the FDA has expressed willingness to accept a modification of the trial's primary endpoint, the Scale for Assessment and Rating of Ataxia, also called SARA, as an acceptable registrational endpoint.
- First patient dosed with BHV-5000 -- In December 2017, enrollment of subjects started for the IND opening study, which tests single and multiple doses of a solid-dose formulation of BHV-5000 in healthy volunteers. BHV-5000 is being developed as a potential treatment for neuropsychiatric disorders such as Rett syndrome. The Company also plans to explore development of BHV-5000 in other potential future indications including neuropathic pain and treatment-resistant depression.
- First patient treated with trigriluzole in Rutgers Cancer Institute collaboration -- As part of a clinical collaboration with Drs. Ann Silk and James Goydos at the Rutgers Cancer Institute of New Jersey, trigriluzole is being evaluated for safety in a Phase 1 trial in combination with PD-1 blocking antibodies in patients with inoperable, advanced or refractory cancers. The study began enrollment in October 2017, and the first patient has started treatment.
- In February 2017, Biohaven closed a second tranche of $40 million as part of a Series A preferred financing that raised $80 million in total.
- In May 2017, Biohaven raised nearly $194 million in its initial public offering on the New York Stock Exchange (NYSE), representing the largest biopharma IPO on NYSE in over 2 years and third largest biopharma IPO in 2017.
