The North America Metabolic Dysfunction–Associated Steatohepatitis (MASH) Treatment Market is witnessing exponential growth, rising from USD 3.70 billion in 2024 to an anticipated USD 17.15 billion by 2033, at a strong compound annual growth rate (CAGR) of 19.3% from 2025 to 2033.

This dynamic expansion is fueled by the increasing prevalence of obesity, Type 2 diabetes, aging population, and groundbreaking advancements in pharmacological therapies designed to combat liver fibrosis and improve MASH resolution outcomes.

Key Market Drivers and Opportunities

Surge in Obesity and Type 2 Diabetes
The rising rates of obesity and metabolic syndrome across North America have driven a sharp increase in MASH cases. It is estimated that over 6 million individuals in the U.S. are affected, contributing to escalating demand for liver-specific treatment solutions.

FDA Approval of Rezdiffra (resmetirom)
The approval of Rezdiffra, the first FDA-cleared drug for MASH treatment, marks a pivotal milestone in liver therapeutics. The drug addresses liver fibrosis and steatosis, significantly improving disease resolution rates and establishing a benchmark for future therapies.

Promising Clinical Pipeline
Multiple therapies are in advanced trial stages. Tirzepatide, an antidiabetic GLP-1 analog, demonstrated up to 73% MASH resolution in clinical trials. Other promising candidates include pegozafermin (FGF21 analog), efruxifermin, and combination regimens that address both metabolic dysfunction and fibrosis reversal.

Strategic Collaborations and Biotech Innovation
Pharmaceutical giants and biotech firms are forming strategic alliances to accelerate clinical development. These partnerships enhance resource sharing and fast-track regulatory pathways for novel drugs targeting the full spectrum of MASH pathophysiology.

Integration of AI and Biomarker-Based Diagnostics
Advancements in non-invasive diagnostics, including AI-assisted biomarker discovery and elastography, are transforming early detection of MASH and enabling precision therapy for patient subgroups based on liver disease staging.

Latest Trends and Developments

• March 2024: Rezdiffra approval triggered broad market adoption with a projected treatment cost of around USD 47,000 annually per patient.

• Clinical Success: Efruxifermin showed 39% fibrosis reversal in advanced MASH patients during Phase 2b trials, reinforcing its potential for regulatory clearance.

• AI in MASH Management: AI-based algorithms and machine learning are now being integrated into diagnostic protocols to enable earlier detection and reduce dependency on invasive liver biopsy.

• Expanded Therapeutic Scope: Combination regimens combining anti-inflammatory, anti-fibrotic, and metabolic agents are progressing through multi-center trials.

Challenges Facing the Market

High Treatment Costs
New-generation MASH therapies, including resmetirom, have high price tags that may limit initial accessibility. Broader insurance coverage and cost-sharing mechanisms are needed.

Diagnostic Gaps
Non-invasive diagnostic tools such as elastography are not yet standard in all clinics, leading to underdiagnosis or delayed diagnosis in early stages.

Competition from Adjacent Therapies
GLP-1 drugs developed for diabetes and obesity, such as semaglutide and tirzepatide, are increasingly being evaluated for their impact on MASH, creating competitive overlap.

Limited Awareness
Despite increasing disease burden, awareness of MASH among general practitioners and patients remains low, leading to missed therapeutic opportunities and underreporting.
