Pharmaceutical company focused on dementia and oncology

Overview

Eisai is a Japanese research-based pharmaceutical company that discovers, develops, and markets prescription medicines under its "human health care (hhc)" concept.

Pfizer, Eisai partner to co-promote Nurtec in Japan.

Pfizer, Eisai partner to co-promote Nurtec in Japan. On Jul 29, 2026 Pfizer Japan Inc. and Eisai Co., Ltd. have announced a new collaboration to co-promote the migraine treatment Nurtec OD Tablet 75mg (rimegepant sulfate hydrate) across Japan beginning September 1, 2026. The agreement is designed to expand awareness of the appropriate use of Nurtec among healthcare professionals and improve access to treatment information for patients living with migraine. While both companies will jointly provide medical information to healthcare institutions nationwide, Pfizer will continue to oversee the drug's development, manufacturing, distribution, and commercialization. Nurtec is an oral calcitonin gene-related peptide (CGRP) receptor antagonist approved for both the acute treatment of migraine attacks and the preventive treatment of migraine. The dual indication makes it one of the few oral therapies that can address both immediate symptom relief and long-term prevention. Under the co-promotion arrangement, Pfizer and Eisai will combine their respective strengths to support the broader adoption of Nurtec in clinical practice. Pfizer, as the product's marketing authorization holder, brings its expertise in developing and commercializing innovative medicines, while Eisai contributes its established presence in neurology, one of the company's strategic therapeutic focus areas. The companies said the collaboration is intended to accelerate the delivery of accurate and timely medical information to physicians and healthcare providers. By leveraging their combined healthcare networks, they aim to ensure that patients who may benefit from Nurtec have greater access to appropriate treatment options. Migraine is a chronic neurological disorder that affects millions of people worldwide and is often accompanied by severe headaches, nausea, sensitivity to light, and sensitivity to sound. Frequent migraine attacks can significantly interfere with work, education, family responsibilities, and overall quality of life. Despite advances in treatment, many patients continue to experience inadequate symptom control or remain undiagnosed and undertreated. With migraine placing a substantial burden on both patients and healthcare systems, the companies believe wider awareness of effective treatment options could help improve disease management and patient outcomes. Pfizer and Eisai said the partnership reflects their shared commitment to supporting people living with migraine by promoting the appropriate use of Nurtec. Through the expanded educational and promotional efforts, the companies aim to help more patients receive timely treatment, reduce the impact of migraine attacks, and regain their everyday lives.

The initiative underscores the companies' commitment to addressing unmet medical needs and enhancing patient care in the neurology sector.

Eisai invests £48M in UK cold-chain pharma packaging hub.

Eisai invests £48M in UK cold-chain pharma packaging hub. 19 Jun 2026 Key takeaways. * Eisai is investing approximately £48 million (US$63.5 million) at its Hatfield, UK, site to build cold-chain packaging and supply capabilities. * The project, supported by the UK Government's LSIMF, aims to strengthen domestic pharma manufacturing and improve supply resilience. * The investment will allow Eisai to bring more packaging operations in-house. Eisai, a Japanese pharmaceutical company, has announced an investment, supported by the UK government under the Life Sciences Innovative Manufacturing Fund (LSIMF), at its manufacturing site in Hatfield, UK, to establish supply chain and packaging capabilities for medicines that require cold-chain management. LSIMF is a capital grants scheme aiming to enhance life sciences manufacturing capabilities in the UK and improve supply resilience. The project is being implemented in multiple phases, with a total investment from Eisai of approximately £48 million (US$63.5 million). Haruo Naito, CEO at Eisai, says: "This strategic investment reflects our long-term commitment to strengthening resilient supply capabilities for our innovative medicines and pipeline products, while further deepening our long-standing relationship with the UK. We value the opportunity to work with the UK government in strengthening life sciences manufacturing and healthcare resilience for the future." Strengthen pharmaceutical manufacturing resilience. The investment is said to align with the UK government's policy to strengthen domestic pharmaceutical manufacturing. The Hatfield site aims to serve as a manufacturing hub serving multiple regions, including Europe, the Middle East, and Africa. Lord Vallance, Minister of State for Science, says: "Building world-class manufacturing capabilities here in the UK will secure the supply of vital medicines, including treatments for Alzheimer's disease, that can transform lives. Eisai's government-backed investment will also support the creation of new skilled jobs in Hatfield and is another example of the benefits of international companies investing in the UK - bolstering our reputation as a life sciences hub while growing our economy." According to Eisai, the investment will help expand the company's manufacturing capabilities, "broadening its role beyond traditional oral solid dose operations to support the packaging and supply of temperature-controlled medicines for injection and infusion." Moreover, the company is set to enhance supply stability and flexibility by transitioning from reliance on external contract manufacturers to an in-house packaging model. The investment covers facilities capable of handling temperature-controlled products, including the expansion of goods receipt and dispatch functions, construction of ambient and cold-chain warehouses, along with installation of packaging buildings and packaging lines. In addition, the site's advanced production flexibility, capacity for multilingual and small-batch packaging, and robust quality management systems will support Eisai's global supply network. In related pharmaceutical packaging manufacturing news, this month, Amcor boosted its healthcare packaging production capacity with a multi-million-dollar investment in its facility in Sira, Karnataka, India, and with a US$35 million investment to open a healthcare packaging coating facility in Subang Jaya, Selangor, Malaysia. Earlier this year, Sharp, a pharmaceutical packaging company, invested over €20 million (US$21.6 million) in its European packaging facilities in response to "strong market demand" for injectables.
