Seven questions, a 60-second thesis frame.
What changed, and when
Novo Nordisk announced a definitive agreement on 09 Oct 2025 to acquire Akero Therapeutics for $54 per share in cash plus a $6 CVR, up to $5.2 billion total consideration. (Company announcement, Akero press release). Independent reports confirm terms and strategic rationale. (Reuters, Financial Times).
60-second thesis frame
Deal adds efruxifermin, an FGF21 analogue in Phase 3 for MASH across F2–F4, to complement Novo’s GLP-1 portfolio and potential MASH indication for semaglutide, raising the probability of a differentiated combo or sequencing strategy in metabolic liver disease. (Company announcement). Peer-reviewed 96-week data in compensated cirrhosis show fibrosis regression signals, providing rare late-stage cirrhosis evidence in MASH. (NEJM article via NATAP PDF). Regulatory path is legible after FDA’s acceptance of surrogate approaches and EU openness to intermediate endpoints and AI-assisted biopsy reading, but payer access norms are forming around Rezdiffra benchmarks and prior auth. (FDA surrogate endpoint update, EMA CHMP AI tool coverage, FDA Rezdiffra approval page). Competitive heat is rising, with Roche buying 89bio’s FGF21 pegozafermin and strong GLP-1 data in MASH. (Roche announcement, NEJM tirzepatide Phase 2, NEJM semaglutide Phase 3).
The seven diligence questions
Clinical
- What is the reproducibility of efruxifermin’s fibrosis-regression signal at 96 weeks in F4, and how did 36-week results compare to longer-term data in NEJM and extension analyses? (NEJM article via NATAP PDF).
- Does SYNCHRONY Histology target one or both standard histology endpoints at 52 weeks, and when is the primary readout expected? (Akero corporate presentation, Akero Q2’25 update).
Payer or Access
- If approved, will access criteria mirror Rezdiffra, including non-biopsy diagnosis pathways and prior authorization scaffolding, and what will be required for cirrhosis stages? (FDA Rezdiffra approval page, UHC PA policy example).
- How will EU and UK HTA bodies view histology versus outcomes for pricing and uptake, given CHMP acceptance of AI-assisted biopsy reads and conditional approval pathways? (EMA AI tool coverage, EMA reflection paper).
Ops or Adoption
- Can Novo scale MASH diagnostics and referral flows beyond biopsy, using NITs and PCP-to-hepatology pathways, to find F2–F4 patients at commercial launch? (AASLD practice resources summary).
Competitive
- How does efruxifermin differentiate from pegozafermin and GLP-1s on fibrosis and outcomes, and could combo or sequencing with semaglutide drive superior real-world liver and cardio-renal endpoints? (Roche–89bio deal, NEJM semaglutide Phase 3, NEJM tirzepatide Phase 2).
Team or Cap table
- What execution risks exist under Novo’s new CEO, and how will integration milestones be tied to SYNCHRONY data timing and CVR triggers? (Reuters CEO coverage, Company announcement).
Red flags
- Phase 3 miss on histology or lack of confirmatory outcomes in F4 would materially erode the thesis. (FDA MASH guidance overview).
- Payer friction if labels require biopsy-like certainty or if PA criteria resemble high-friction Rezdiffra analogues, slowing uptake. (UHC PA policy example).
- Competitive displacement if GLP-1 monotherapy delivers comparable fibrosis benefit, or if Roche’s pegozafermin reads out stronger. (NEJM semaglutide Phase 3, Roche–89bio deal).
Next catalyst
HSR and other antitrust clearances and Akero shareholder approval, closing targeted around year-end 2025, plus first Phase 3 data from SYNCHRONY Real-World in first half 2026. (Company announcement, Akero Real-World timing).

FAQs
- What exactly changed with Novo Nordisk’s acquisition of Akero Therapeutics on 09 Oct 2025, and why does it matter for MASH? The company agreed to buy Akero for $54 per share plus a $6 CVR, adding efruxifermin, an FGF21 analogue in Phase 3 for MASH. The asset targets fibrosis regression and could complement Novo’s GLP-1 franchise. (Company announcement, Reuters).
- What is the regulatory path after the 09 Oct 2025 announcement in the US, UK, and EU? FDA recently accepted a surrogate endpoint proposal pathway in MASH, while EMA signaled flexibility on intermediate endpoints and AI-assisted biopsy reading, shaping potential accelerated or conditional approvals. UK processes would follow MHRA guidance with RWD options. (FDA surrogate endpoint update, EMA reflection paper, MHRA RWD trial guidance).
- Which endpoints in Akero’s SYNCHRONY program are pivotal, and how meaningful are prior effect sizes? Histology co-primaries or composites at 52 weeks for F2–F3 and fibrosis regression with outcomes follow-up for F4 underpin Phase 3, building on 96-week Phase 2b fibrosis regression signals in F4 and strong F2–F3 data. (Akero program overview, NEJM article via NATAP PDF, HARMONY Phase 2b PubMed).
- What safety considerations matter post-deal and do they change real-world use? FGF21 class effects include GI events and lipid changes; long-term cirrhosis safety and bone endpoints require monitoring. Label-defining safety will be compared to Rezdiffra’s experience and GLP-1 hepatic safety in MASH. (NEJM F4 article, FDA Rezdiffra approval page).
- How will major US payers treat access if efruxifermin is approved, and are codes available? Rezdiffra policies preview PA frameworks and diagnosis documentation without mandatory biopsy, implying similar criteria may emerge for next entrants; coding will follow standard NDC for oral or J-code for injectables if assigned. (UHC PA policy example, DailyMed NDCs reference).
