In another cautionary tale of kicking all the tires before an acquisition, Pfizer Inc. agreed to a nearly $60 million settlement to resolve a whistleblower’s claims that Biohaven Pharmaceutical Holding Co. Ltd. was paying kickbacks to induce prescriptions of its migraine drug ahead of Pfizer’s $11.6 billion acquisition of the company in October 2022.
Pfizer Inc. is taking over Biohaven Pharmaceutical Holding Co. Ltd. for $11.6 billion to bring aboard Nurtec ODT (rimegepant), the calcitonin gene-related peptide (CGRP) receptor antagonist first approved in February 2020 for acute migraine in adults with or without aura.
Biohaven Pharmaceutical Holding Co. Ltd. signed a deal that could be worth more than $1 billion to take over Channel Biosciences LLC, a subsidiary of Knopp Biosciences LLC, and its Kv7 channel targeting platform. A key part of the deal is BHV-7000, formerly known as KB-3061, described as a potent activator of Kv7.2 and Kv7.3, key subunits involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy. The compound is expected to enter clinical investigation this year, with focal epilepsy as the lead indication.
In the Biohaven Pharmaceutical Holding Co. Ltd. and Pfizer Inc. collaboration to commercialize Nurtec ODT (rimegepant) outside the U.S., Biohaven will receive tiered double-digit royalties on ex-U.S. net sales as well as milestone payments of up to $1.24 billion. The target: more than 1 billion migraine sufferers worldwide with lots of clinical competition.
Although 14 of the 17 stocks that make up BioWorld’s Neurological Disease Index (NDI) dropped in value over the last month, the index is still ahead by about 9% this year, with a huge surge by Prothena Corp. plc leading the way.
Stock market exuberance, particularly in favor of an innovative industry working to pull the world out of the deadly COVID-19 pandemic, led to drug developers shares surging 30% in 2020. But if one thing is certain, it is this: Markets usually pull back and that is partially why BioWorld’s Drug Developers Index is showing only a 2.06% gain so far this year, in contrast to both the Nasdaq Biotechnology Index and the Dow Jones Industrial Average, which are up 6.28% and 10.96%, respectively.
Public biopharmaceutical companies did manage to attract some investors off the sidelines in May with medical conference season getting into full gear. However, it was generally another lackluster month, with the Nasdaq Biotech index dropping 2% in the period in contrast to the broader markets with the Dow Jones Industrial Average growing by 2%. The sector, however, could get a significant boost in the next few days if the FDA gives the green light to Biogen Inc. and Eisai Co. Ltd.’s experimental Alzheimer’s disease therapy, aducanumab, a recombinant chimeric human IgG1 monoclonal antibody targeting beta-amyloid, that could be the first disease-modifying therapy for an indication that has seen no novel therapies approved in more than 15 years.
The second oral CGRP antagonist to win FDA approval for acute migraine care is now the first to add preventive treatment to its label, marking a valuable win for Biohaven Pharmaceutical Holding Co. Ltd. and its oral dissolving tablet, Nurtec (rimegepant). The U.S. approval, for preventive treatment of episodic migraine, officially blesses a use for the medicine already adopted by many doctors, Piper Sandler analyst Christopher Raymond wrote, while opening up a potentially rich new stream of revenue for Biohaven.
Investors appear to be maintaining a bullish outlook on biopharma companies developing innovative medicines, with the BioWorld Drug Developers index currently tracking up over 5% in value so far this month heading into third-quarter earnings season.
