A Phase 3 Study Evaluating the Safety and Efficacy of Denifanstat in Patients With MASLD and MASH

A phase 3, randomized, double-blind, placebo-controlled study evaluating the safety and tolerability of denifanstat 50 mg compared to placebo in patients with metabolic dysfunction-associated steatotic liver disease (MALSD)/metabolic dysfunction-associated steatohepatitis (MASH) after 52 weeks of treatment.

Up to 2000 patients will be randomized to receive either denifanstat 50 mg or placebo.

1. T2DM

   OR
2. At least 2 out of 4 of the following:

   * BMI ≥30 kg/m2,
   * Hypertension, or on active antihypertensive treatment
   * Elevated fasting serum TGs or on active treatment for hypertriglyceridemia
   * Reduced fasting serum HDL-c, or on active treatment for dyslipidemia.

5. For patients with T2DM:

1. HbA1c ≤9.5%
2. If treatment naive: patients must have been diagnosed for at least 12 weeks prior to screening

6. Suspected or confirmed diagnosis of MASH or MASLD or non-invasively diagnosed MASH or MASLD

4. Presence of cirrhosis on liver histology and/or cross-sectional imaging evidence consistent with cirrhosis and/or portal hypertension.

5. Current or historical clinically evident hepatic decompensation.

6. Evidence of another form of active liver disease.

7. Positive serologic evidence of current infectious liver disease.

8. MELD score ≥12.

9. Planned or history of liver transplantation.

10. Prior or planned bariatric surgery.

11. Gain or loss of \>5% of body weight in the 3 months or \>10% of body weight in the 6 months prior to screening, qualifying liver biopsy, and the baseline visit (V1).
