Roche enters into a definitive merger agreement to acquire 89bio, and its phase 3 FGF21 analog for the therapy

Roche, announced that it has entered into a definitive merger agreement to acquire 89bio, a publicly listed clinical-stage biopharmaceutical company pioneering the development of innovative therapies for the treatment of liver and cardiometabolic diseases. 89bio’s pegozafermin is a FGF21 analog currently in late-stage development for MASH in moderate and severe fibrotic patients (F2 and F3 stages) as well as cirrhotic patients (F4 stage). The transaction is expected to close in the fourth quarter of 2025.

This acquisition underscores Roche’s dedication to advancing innovative therapies in cardiovascular, renal, and metabolic diseases (CVRM), especially for patients affected by overweight, obesity, and related health challenges such as MASH. Pegozafermin offers a distinct mechanism of action that not only holds the potential for enhanced efficacy and tolerability but also unlocks opportunities for future combination development with incretins, creating synergies with Roche’s CVRM portfolio. Acquiring 89bio, therefore, fosters Roche’s activities to build a robust and differentiated pipeline that targets additional causes of metabolic disease.

“This acquisition further strengthens our portfolio in cardiovascular, renal, and metabolic diseases and offers opportunities to explore combinations with existing programmes in our pipeline,” said Thomas Schinecker, Roche Group CEO. “We are highly encouraged by pegozafermin’s potential to become a transformative treatment option in MASH, one of the most prevalent comorbidities of obesity, and to meet diverse patient needs associated with this complex disease. With its combined anti-fibrotic and anti-inflammatory mechanism, pegozafermin could potentially offer best-in-disease efficacy for all moderate to severe MASH patients.”
