Biogen (BIIB) Partner Eisai Seeks Nod for Lecanemab in Japan

Read MoreHide Full Article

Biogen Inc. (BIIB - Free Report) and partner Eisai announced that the latter submitted a marketing authorization application seeking approval for their anti-amyloid beta protofibril antibody candidate, lecanemab to treat mild cognitive impairment due to Alzheimer’s disease (AD) mild AD dementia (collectively known as early AD) with confirmed presence of amyloid pathology in the brain to the Pharmaceuticals and Medical Devices Agency.

The filing in Japan was based on data from the phase III Clarity AD study and the phase IIb clinical study (Study 201), which evaluated lecanemab for the given indication.

Data from the Clarity AD study showed that treatment with lecanemab led to highly statistically significant results and met its primary endpoint. All key secondary endpoints also showed highly statistically significant results.

Shares of Biogen have rallied 20.4% in the past year against the industry’s decline of 12.8%.

Earlier this month, the FDA granted accelerated approval to lecanemab under the brand name Leqembi to treat early Alzheimer’s disease (early AD).

Eisai has priced Leqembi at a wholesale acquisition cost of $26,500 per year.

Eisai also filed a supplemental biologics license application to the FDA to get traditional approval for Leqembi. Eisai plans to file an MAA for lecanemab in Japan by March 2023.

Last week, BIIB filed a marketing authorization application to the European Medicines Agency, seeking approval for lecanemab to treat early Alzheimer’s disease (mild cognitive impairment due to Alzheimer’s disease [AD] and mild AD dementia).

Biogen has developed lecanemab in collaboration with Eisai, with the latter leading the clinical development and regulatory submissions. Eisai and Biogen will co-commercialize and co-promote the drug. The companies also developed another anti-amyloid antibody, Aduhelm, which was approved by the FDA in June 2021 but failed to generate meaningful sales.

Aduhelm’s FDA approval in June 2021 faced a lot of criticism about its mixed efficacy results, the FDA selection of the accelerated approval path and the regulatory process in general. The FDA approved Aduhelm despite an FDA advisory committee voting against its approval due to mixed outcomes data from the ENGAGE and EMERGE phase III studies. All these issues affected demand, patient access and reimbursement for Aduhelm, which resulted in a slow launch.

Some other large-cap pharma companies like Roche (RHHBY - Free Report) and Eli Lilly (LLY - Free Report) are developing beta amyloid-targeting drugs for AD indication. The Alzheimer’s candidates of these companies are in late-stage development or review and are expected to be launched in the upcoming months.

Eli Lilly’s BLA seeking accelerated the approval of donanemab, based on data from the TRAILBLAZER-ALZ study, is already under review with the FDA. A decision is expected in early 2023. Lilly also expects a data readout from the phase III TRAILBLAZER-ALZ 2 study by mid-2023, which, if positive, will form the basis of its application for traditional regulatory approval for donanemab.

Roche’s phase III GRADUATE I and II studies on a key Alzheimer’s pipeline candidate, gantenerumab, failed to meet the primary endpoint of slowing clinical decline in people with early Alzheimer’s disease in November 2022. The level of beta-amyloid removal by gantenerumab was less than expected. Roche was developing the candidate in collaboration with MorphoSys.
