Astellas' R&D isn't defined by therapeutic area or technology. Instead, their "focus area approach" creates a "triangle" of core biology, the best modality, and the right patient population. This model is designed to generate multiple follow-on programs, like their KRAS degraders, by pivoting any corner of this triangle.
To offset the impending 2027 patent loss for its blockbuster drug Xtandi, Astellas is not relying on a single successor. The company is betting on five distinct strategic brands across bladder cancer, AML, geographic atrophy, and women's health to collectively replace the revenue and mitigate the impact.
Astellas isn't resting on its first-to-market Claudin 18.2 antibody. It's proactively developing next-generation therapies—a CD3 bispecific to reach more patients and an in-licensed ADC for a potential chemo-free regimen. This multi-asset strategy aims to create an enduring leadership position in this specific cancer target.
