In the pharmaceutical world, mergers and acquisitions are often transformative, shaping the trajectory of innovation and accessibility to critical treatments. In May 2022, Pfizer announced a pivotal $11.6 billion acquisition of Biohaven Pharmaceuticals, a company known for its breakthrough treatments for migraine. This acquisition strengthens Pfizer’s position in the growing field of neurological treatments and emphasizes the pharmaceutical giant’s commitment to expanding beyond its COVID-19 vaccine success. The deal also highlights how big pharmaceutical companies are increasingly turning to specialized firms like Biohaven to bolster their portfolios with modern therapies.
This article explores the significance of this acquisition, what it means for patients suffering from migraines, and how Pfizer’s expanding footprint in neurology could redefine treatment options.
The Background of the Deal

On May 10, 2022, Pfizer announced its intent to acquire Biohaven Pharmaceuticals, specifically targeting Biohaven’s migraine portfolio, which includes the FDA-approved Nurtec ODT (rimegepant). Nurtec ODT is a first-in-class calcitonin gene-related peptide (CGRP) receptor antagonist used for the acute treatment and prevention of migraines. The drug had already achieved blockbuster status, generating more than $400 million in sales in 2021, making it a key asset for Pfizer’s expansion into neurological treatments.
Biohaven, a leader in migraine treatment innovation, focuses heavily on the development of CGRP therapies. CGRP antagonists are part of a new wave of migraine medications that target the protein responsible for causing inflammation and pain in the brain during migraine attacks. This approach offers patients relief from both acute migraine pain and frequent, recurring migraines, a market Pfizer was eager to tap into.
Under the terms of the deal, Pfizer agreed to pay $11.6 billion in cash to acquire Biohaven, including all of its migraine-related assets. However, Biohaven’s non-CGRP assets, including therapies for neurological and psychiatric disorders, were spun off into a separate entity, New Biohaven, which will continue to focus on other areas of drug development.
Pfizer’s Strategy: Beyond COVID-19 and into Neurology

Pfizer’s acquisition of Biohaven represents a strategic shift in its focus beyond the COVID-19 vaccines and treatments that dominated its recent success. The pharmaceutical giant had already partnered with Biohaven in 2020, investing $350 million for a 2.6% stake and exclusive marketing rights outside the U.S. for Biohaven’s migraine treatments. However, this acquisition allows Pfizer to fully integrate Biohaven’s CGRP portfolio into its own pipeline and take complete control over its marketing and distribution.
This move strengthens Pfizer’s presence in the neurology space, an area with significant growth potential as treatments for neurological disorders remain largely underserved. The global migraine treatment market is expected to grow rapidly, reaching over $12 billion by 2026, driven by rising awareness and demand for better preventive treatments. By acquiring Biohaven, Pfizer gains a competitive edge in this expanding market, positioning itself as a leader in migraine therapy.
Additionally, Pfizer’s acquisition comes at a time when the company is eager to diversify its revenue streams. While its COVID-19 vaccine, Comirnaty, and antiviral treatment, Paxlovid, have been enormously profitable, Pfizer is looking ahead to a post-pandemic world. Neurology, and specifically migraine treatment, offers a lucrative opportunity for the company to continue its growth trajectory.
What This Means for Migraine Patients
For the millions of people who suffer from migraines, the Pfizer-Biohaven merger could have a positive impact on access to cutting-edge treatments. Migraine is a debilitating neurological condition affecting more than 1 billion people worldwide, with patients often seeking new options after conventional treatments fail.
Nurtec ODT, Biohaven’s leading product, has been a game-changer in migraine management. Approved by the FDA for both the acute treatment and prevention of migraines, Nurtec is taken orally, offering patients a convenient alternative to injectable CGRP therapies. As one of the first medications capable of addressing both acute and preventive needs, it has quickly become a preferred option for migraine sufferers.
With Pfizer’s global reach, extensive distribution networks, and marketing capabilities, the acquisition could significantly expand access to Nurtec ODT, making it available to more patients worldwide. Pfizer’s ability to scale production and push for regulatory approvals in more countries will likely lead to greater availability of migraine therapies, particularly in underserved markets.
Furthermore, Pfizer’s financial muscle and expertise in conducting clinical trials could accelerate the development of new treatments within the CGRP space. Biohaven’s pipeline includes next-generation migraine drugs, such as zavegepant, an intranasal CGRP antagonist. Pfizer’s involvement could speed up the approval and commercialization of these treatments, offering patients additional options for migraine management.
Broader Implications for the Pharmaceutical Industry

Pfizer’s acquisition of Biohaven is part of a broader trend in the pharmaceutical industry, where large firms are increasingly acquiring smaller, specialized companies to gain access to innovative therapies. This “bolt-on” acquisition strategy allows big pharmaceutical companies to stay competitive by integrating the latest scientific advancements into their portfolios without having to spend years developing those treatments in-house.
For companies like Biohaven, being acquired by a larger entity can provide the resources needed to accelerate research and bring therapies to market faster. In this case, the acquisition allows Biohaven’s migraine therapies to benefit from Pfizer’s global marketing and distribution capabilities, while also providing the resources for further innovation in neurological treatments.
This deal also underscores the growing importance of migraine treatment as a high-growth sector within neurology. As awareness of migraines and the impact they have on quality of life increases, demand for innovative treatments is rising. Pfizer, with its acquisition of Biohaven, is well-positioned to capitalize on this trend.
Summary: A Win for Pfizer and Migraine Patients?
Pfizer’s acquisition of Biohaven is a bold move that has significant implications for both the company and the millions of people suffering from migraines. With Biohaven’s cutting-edge CGRP therapies now under its control, Pfizer is set to become a major player in the neurology space, particularly in migraine treatment. The deal gives Pfizer access to a rapidly growing market, diversifies its portfolio, and positions it to continue driving growth post-pandemic.
For migraine patients, the merger offers hope that modern treatments like Nurtec ODT will become more widely available, and that future therapies in Biohaven’s pipeline will reach the market sooner. As Pfizer integrates Biohaven’s products and expertise into its operations, the future of migraine treatment looks bright.
