Eisai has signed an agreement for the divestiture of rights for Merislon and Myonal, two of its long-standing products in Japan, to Kaken Pharmaceutical. The transaction is valued at Y3.8bn ($25.10m). Merislon treats vertigo and equilibrium disturbances and Myonal is a muscle relaxant, which patients have used since their respective launches in 1969 and 1983. The agreement stipulates that Eisai will complete the transfer of marketing capabilities by March 2025, followed by manufacturing and marketing approval transfer. The deal will not impact Eisai’s consolidated financial forecast for 31 March 2024. The company stated: “Eisai has determined that divesting rights for these products to Kaken, which has strengths in the products’ disease areas, is the optimal choice to ensure they continue contributing to a greater number of patients.” Eisai will continue to focus on creating and delivering products to target diseases with higher unmet medical needs such as neurology, oncology and ...
More than two years after Aduhelm’s controversial and ill-fated FDA accelerated approval, Biogen is discontinuing the Alzheimer’s disease therapy after walking a rocky path. Wednesday, Biogen said it’s pulling all efforts from the first-of-its-kind anti-amyloid beta therapy to focus on Leqembi, its Eisai-partnered newer medicine, and its pipeline candidates. The newer drug, Leqembi, won a full FDA approval early last year, making the partners’ marketing efforts on the therapy much simpler than was the case with Aduhelm. Biogen is taking a $60 million charge and is discontinuing all development and sales of Aduhelm, the company said. It’s terminating the ENVISION clinical study, which sought to confirm the benefit of the medicine as required under its 2021 accelerated approval. The decision follows Biogen’s move to launch a strategic review in early 2023 under new CEO Chris Viehbacher, the former Sanofi chief who joined the Massachusetts drugmaker in November 2022. During that ...
By Connor Lynch Pictured: Merck logo on building/iStock, Sundry Photography Merck and Eisai have dropped another joint drug trial after disappointing Phase III results. The companies announced Friday that they would be ending their combination treatment of Keytruda and Lenvima, respectively, after a second interim analysis found no improvement in overall survival. The LEAP-010 trial was evaluating the safety and effectiveness of Merck’s anti-PD-1 therapy in combination with Eisai’s multiple receptor tyrosine kinase inhibitor for metastatic or unresectable head and neck squamous cell carcinoma (HNSCC). An independent monitoring committee conducted two interim analyses over the course of 11 months. Initial results from the first analysis were promising: the therapy combo met two of the trial’s three primary endpoints of progression-free survival and objective response (OS) rate. However, the treatment failed to show evidence of meeting the third endpoint, overall survival, in the second analysis. The companies in Friday’s announcement said ...
After a full FDA approval last week triggered Medicare coverage of Eisai and Biogen’s Leqembi, doctors are still trying to work out the logistics of testing and reimbursement. But at least two experts remain positive about the drug’s efficacy and safety profile.The new Leqembi label carries a boxed warning about the risks of brain bleeding and swelling known as amyloid-related imaging abnormalities (ARIA). But two Alzheimer’s opinion leaders suggested the side effect is manageable typically by extensive monitoring in the first six months, Leerink Partners analysts said in a Wednesday note. But the two experts were split on whether they intend to treat patients with the ApoE ε4 genetic trait. The FDA label requires testing for that biomarker before initiating Leqembi to inform the risk of ARIA. While one expert felt comfortable giving Leqembi to APOE4 carriers as long as the patients are informed of the risk, the other ...
The US Food and Drug Administration (FDA) has granted traditional approval for Eisai and Biogen’s Leqembi (lecanemab-irmb) 100mg/mL injection to treat Alzheimer’s disease (AD) in adults. With the approval of the supplemental biologics licence application (sBLA), Leqembi becomes the first therapy to slow disease progression rate and cognitive and functional decline in AD patients. This development is based on findings from the Phase III portion of Eisai’s Clarity AD clinical trial. Trial data showed that the product met the Leqembi primary endpoint and all crucial secondary endpoints, and also demonstrated clinical benefit. In January 2023, the regulatory agency granted accelerated approval for Leqembi. Leqembi is a humanised immunoglobulin gamma 1 (IgG1) monoclonal antibody that targets aggregated soluble (protofibril) and amyloid beta’s (Aβ) insoluble forms. Eisai CEO Haruo Naito stated: “The FDA approved Leqembi under the traditional approval pathway, making Leqembi the first and only approved anti-amyloid Alzheimer’s disease treatment shown ...
It’s official: Roughly half a year after the FDA granted an accelerated nod to Eisai and Biogen’s new Alzheimer’s disease med lecanemab, the companies have converted that green light into a full-fledged, traditional approval. Now, the drug—also known as Leqembi—is set to unshackle itself from a strict coverage determination by the Centers for Medicare & Medicaid services (CMS). With a full approval in hand, Leqembi has become the first treatment shown to reduce the rate of disease progression and slow cognitive and functional decline in adults with Alzheimer’s under the traditional approval pathway, Eisai Executive Vice President Alex Scott, who oversees government affairs, said in an interview. Those benefits stand across a “broad patient group that’s generalizable to the whole Medicare population,” he added. Leqembi won an accelerated FDA approval in January based on its ability to reduce amyloid beta plaque, a marker of Alzheimer’s disease that’s believed to be ...
After a daylong discussion among experts on an FDA advisory committee, Eisai and Biogen’s Leqembi is heading into the final stretch of its regulatory review on strong footing.During a Friday meeting, members of the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee took a careful look at the data behind the partners’ Alzheimer’s disease drug. Ultimately, the group voted 6 to 0 that the drug’s Clarity AD study verify its clinical benefit. In the discussion portion of the meeting, advisory committee members described the trial results as “robust,” “meaningful,” “consistent” and “significant.” Now, it’s up to the FDA to decide whether to follow the advisory committee’s guidance. The agency is expected to decide on the application by July 5. Before the Friday discussion, the FDA released its own briefing document that appeared to outline agency support for a full approval. During the meeting, the FDA’s acting director of the ...
By Rosemary Scott Pictured: Three side-by-side scans of a human brain/iStock, semnic The FDA released briefing documents Wednesday that signal it is likely to grant Eisai and Biogen’s Leqembi (lecanemab) full approval to treat Alzheimer’s disease on its decision date in July. The documents come just two days before an advisory committee is scheduled to vote on whether to recommend the drug’s approval. The FDA has asked the six members of the advisory committee to answer the following question: Do the results of a pivotal trial dubbed Study 301 (CLARITY AD) verify the clinical benefit of lecanemab for the treatment of AD? But it appears the agency may have already decided for itself. Both the briefing documents and the committee’s decision will be based on the Study 301results. In the documents, the FDA stated that the data from the trial showed “consistently favorable results for the primary and secondary endpoints,” ...
As Alzheimer’s disease partners Eisai and Biogen lay the groundwork for a wider launch of Leqembi, their efforts center on winning a full FDA approval. Wednesday, that vision came into better focus as the FDA released a document showing how the agency views the drug.In advance of a highly anticipated FDA advisory committee set for Friday, the agency released a briefing document that appears to support a full FDA approval for Leqembi. On efficacy, the agency said the drug’s treatment effect in its pivotal trial, called Study 301, is “supported by the consistently favorable results for the primary and secondary endpoints across the prespecified subgroups of interest.” In the study, investigators tested Leqembi against placebo in patients with mild cognitive impairment due to Alzheimer’s or mild Alzheimer’s dementia. The study measured the drug’s efficacy on an endpoint called the Clinical Dementia Rating-Sum of Boxes at 18 months of treatment. On ...
Eisai is the latest drugmaker to be hit with a ransomware attack.The Japanese company said it “immediately” set up a company-wide task force after suffering a cyberattack Saturday night. Now, it’s working to respond with external experts and law enforcement officials, Eisai said in a statement. The possibility of data leaks is currently under investigation, the company said. Eisai expects it will take “some time to gauge the full extent of the incident.” During the response, Eisai took some of its computer systems, both inside and outside of Japan, offline. For now, its corporate websites and email systems remain operational. As for the impact on the company’s earnings, Eisai is “carefully examining” any potential impact on its earnings forecast and will announce “as soon as possible” if revisions are necessary. Japan has seen an increasing amount of cyberattacks recently, according to The Japan Times. An official at the National Center ...
