Swiss pharma giant Roche has agreed to acquire US-based biotech 89bio for up to $3.5 billion. The deal immediately expands Roche’s footprint in the treatment of liver diseases and marks a calculated entry into a high-growth therapeutic market.
89bio’s lead drug, pegozafermin, is central to Roche’s strategy. The acquisition brings Roche closer to leadership in metabolic dysfunction-associated steatohepatitis, a condition affecting millions globally, and accelerates the pharmaceutical firm’s ambitions in cardiometabolic therapy.
What drives Roche's bold move into liver disease?
The rising prevalence of MASH, linked to obesity and diabetes, presents significant commercial and scientific opportunity. Roche aims to capture a meaningful share of an estimated $31.8 billion market by 2033, nearly four times larger than in 2024.
By acquiring 89bio, Roche signals intent to compete directly with major players already active in the space.
Roche’s CEO Thomas Schinecker highlighted pegozafermin’s promise: "We are highly encouraged by pegozafermin’s potential to become a transformative treatment option in MASH, one of the most prevalent comorbidities of obesity."
The size and complexity of the deal's payment structure reflect Roche's history of making significant investments at strategic inflection points.
Did you know?
FGF21, the basis for pegozafermin, was first discovered in 2005 and has since become a focus for metabolic disease research.
How does pegozafermin stand out among treatments?
Pegozafermin is a Phase 3 version of fibroblast growth factor 21, created to address both scarring and inflammation in the liver. This differentiates it from most competitors, which focus narrowly on metabolic or fibrotic mechanisms.
The drug’s broad therapeutic window could address moderate to severe MASH, including cases with advanced fibrosis and cirrhosis.
Unlike first-generation treatments, pegozafermin’s design is meant to reduce adverse events and improve efficacy.
Analysts believe the drug’s potential to hit multiple disease pathways at once will be key in securing regulatory approval and commercial traction against rivals such as Novo Nordisk’s Wegovy and Madrigal Pharmaceuticals’ Rezdiffra.
What does the competitive MASH market look like now
The liver disease treatment arena has become fiercely competitive. Novo Nordisk’s Wegovy recently won FDA approval for MASH and is the first GLP-1 therapy to address this indication.
As of 2024, Madrigal Pharmaceuticals is leading the market with Rezdiffra, the first drug specifically approved for MASH, launching at a price point close to $47,400 annually.
Analysts project that the patient pool in the United States alone will grow from 22 million to 27 million by 2030. This anticipated surge is driving record spending and aggressive deal-making among top pharma companies.
Roche’s buy-in elevates the firm into direct competition with incumbents for both patient share and innovative drug development.

How will Roche integrate 89bio for strategic growth?
Roche has structured the acquisition with an initial $2.4 billion cash payment, plus contingent value rights up to $6 per share based on regulatory and commercial milestones.
These payouts will depend on key triggers, including the approval and successful launch of pegozafermin in advanced MASH patients and the drug’s sales performance.
Upon closing, 89bio’s staff will join Roche’s Pharmaceuticals Division, contributing expertise in metabolic diseases.
The addition of pegozafermin fortifies Roche’s pipeline and expands its capabilities across cardiovascular and renal treatment areas. A coordinated global rollout is expected if clinical results continue to show promise.
What does this mean for future therapies in metabolic diseases
The acquisition is already being viewed as a catalyst for accelerating innovation in the metabolic disease space.
Roche’s investment could spur additional research collaborations and new approaches to targeting MASH and related conditions.
Industry experts anticipate ripple effects in regulatory trends and cross-company partnerships.
Looking ahead, Roche’s move signals greater integration of biotech advances into traditional pharma business models and fuels optimism for broader access to next-generation liver therapies.
The competitive landscape is set for further evolution, driven by patient needs and sector-wide scientific progress.
Roche’s 89bio deal brings new momentum to metabolic disease treatment and may reshape pricing and access standards globally in the years ahead.
