Shaping the Future of MASH Care

Our pipeline is anchored in advancing therapies for metabolic dysfunction-associated steatohepatitis (MASH), guided by our expertise in liver care and commitment
to patients.

Our Pipeline

Resmetirom

Oral THR-β agonist

POPULATION

Additional MASH Assets

Three exploratory assets in varying stages of development

  1. Ervogastat Phase 2b trial completed by Pfizer. Resmetirom/ervogastat Phase 1 drug-drug interaction trial expected to initiate in 4Q26; Phase 2 combination trial expected to initiate in 2027 following regulatory discussions.
  2. MGL-2086 Phase 1 single ascending dose trial initiated in 2Q26.
  3. MGL-0795 (formerly ARO-PNPLA3) monotherapy Phase 1 trial completed by Arrowhead.

Our Resmetirom Clinical Development Program

Madrigal has established the leading clinical development program in MASH, including multiple Phase 3 clinical trials:

Pivotal MAESTRO-

NASH Study

Patients with noncirrhotic MASH with moderate to advanced fibrosis (F2-F3)

MAESTRO-NAFLD-1 
Safety Study

The first noninvasive Phase 3 study in MASLD (presumed MASH) (F1-F3)

MAESTRO-NASH-OUTCOMES Cirrhosis Study

An outcomes study in patients with well-compensated MASH cirrhosis (F4c)
