Fierce Pharma Asia—Astellas' investment focus; Mitsubishi Tanabe's buyout; Leqembi's 'expansion phase'

Astellas is shifting its investment focus toward more established modalities and later-stage opportunities, its chief strategy officer said. Mitsubishi Tanabe Pharma is being sold to Bain Capital for about $3.3 billion. Eisai expects a Leqembi "expansion phase" on the horizon. And more.

1. Astellas shifts investment focus to later-stage opportunities amid reprioritization

Despite Astellas' early-stage programs in novel technologies, the company is trying to spend more energy on more established therapeutic approaches, the company’s chief strategy officer Adam Pearson said. As part of an R&D repriortization exercise, Astellas will “generally shift our resources to focus on slightly later-stage opportunities,” he explained.

After reports of buyout talks, Bain Capital has inked a deal to acquire Mitsubishi Tanabe Pharma from the Japanese drugmaker’s parent, Mitsubishi Chemical Group, for 510 billion Japanese yen ($3.3 billion). During the last nine months of 2024, Tanabe grew sales by 3% to about 2.3 billion, benefiting from Japanese sales of Mounjaro, which it licenses from Eli Lilly.

After years of slow growth, Eisai expects its Biogen-partnered Leqembi is about to reach an “expansion phase.” Eisai’s chief operating and growth officer Keisuke Naito made that projection because the Alzheimer’s drug could soon have better blood-based diagnostics—versus PET scans or cerebrospinal fluid tests—and easier dosing formats.

After an FDA rejection, Astellas’ geographic atrophy med Izervay has secured a much-needed approval that has now lifted a 12-month dosing limitation on the drug’s U.S. label. After a November complete response letter, Astellas noted that many doctors had paused Izervay use for patients who reached the 12-month mark, leading to a sales growth hiatus in the fourth quarter.
