Resmetirom is a once-daily, oral thyroid hormone receptor beta-selective agonist. The FDA granted the drug breakthrough therapy designation and priority review.
The approval is based on the phase 3 MAESTRO-NASH trial, in which resmetirom was superior to placebo at achieving resolution of nonalcoholic steatohepatitis (NASH) and improving liver fibrosis in both 80-mg and 100-mg doses.
The trial used the earlier nomenclature of NASH and nonalcoholic fatty liver disease (NAFLD). An international consensus group has since changed these terms to MASH and metabolic dysfunction–associated steatotic liver disease (MASLD), respectively. (Note that the terms NASH and NAFLD will be used to discuss the trial results in this article to align with the trial’s original language.)
The results were published online February 6 in The New England Journal of Medicine.
“The approval of the first medication for NASH is a true game-changer for healthcare providers, the research community and, most importantly, patients living with this serious liver condition,” lead MAESTRO-NASH investigator Stephen Harrison, MD, gastroenterologist, hepatologist, and chairman of Pinnacle Clinical Research and Summit Clinical Research, San Antonio, Texas, said in a news release. 
“Based on the robust efficacy and safety data generated in two large Phase 3 MAESTRO studies, I believe Rezdiffra will become the foundational therapy for patients with NASH with moderate to advanced liver fibrosis. Importantly, we continue to study Rezdiffra to determine if the positive results observed in the MAESTRO studies will lead to reduced risk of progression to cirrhosis, liver failure, need for liver transplant and premature mortality,” Dr. Harrison added.
Addressing an Unmet Need
MASH is a progressive liver disease and the leading cause of liver-related mortality. The disease affects an estimated 1.5 million adults in the United States, of which, roughly 525,000 have MASH with significant fibrosis. Until now, there was no FDA-approved medication.
In the ongoing MAESTRO-NASH, 996 adults with biopsy-confirmed NASH and significant stage 2-3 fibrosis were randomly assigned to receive oral once-daily resmetirom (80 mg or 100 mg) or placebo.
Patients were followed for 52 weeks, at which point, they were assessed for the dual primary endpoints of NASH resolution (including a reduction in the NAFLD activity score by ≥ 2 points) with no worsening of fibrosis and an improvement (reduction) in fibrosis by at least one stage with no worsening of the NAFLD activity score.
Patients receiving resmetirom had a significant improvement across both doses and both primary endpoints.
At 52 weeks, NASH resolution with no worsening of fibrosis was achieved in 25.9% and 29.9% of the patients in the 80-mg and 100-mg groups, respectively, compared with 9.7% on placebo.
Fibrosis improved by at least one stage with no worsening of the NAFLD activity score in 24.2% and 25.9% of patients in the 80-mg and 100-mg groups, respectively, compared with 14.2% on placebo.
The trial also met multiple secondary endpoints, including statistically significant reduction from baseline in liver enzymes (alanine transaminase, aspartate aminotransferase, and gamma-glutamyl transferase) and low-density lipoprotein cholesterol with resmetirom compared with placebo.
Improvement in fibrosis biomarkers and relevant imaging tests were also observed in resmetirom treatment groups compared with placebo.
The most common adverse events included diarrhea and nausea, which typically began early in treatment and were mild to moderate in severity. Pruritus, abdominal pain, vomiting, constipation, and dizziness were also reported.
Resmetirom is expected to be available to patients in the United States in April and will be distributed through a limited specialty pharmacy network.
Full prescribing information is available online. Prescribing information does not include a liver biopsy requirement for diagnosis.
