Phase 3 MAESTRO Clinical Development Program

NAFLD, nonalcoholic fatty liver disease; NASH, nonalcoholic steatohepatitis; OLE, open-label extension.

  • At Week 52, NASH resolution and fibrosis improvement were achieved in significantly more patients treated with resmetirom versus placebo (P<0.001)
  • At Week 24, LDL-C was reduced from baseline with resmetirom versus placebo (P<0.001)

  • The results of additional biopsy endpoints and sensitivity analyses were generally supportive of the results of the primary analyses of the dual primary endpoints
  • At Week 52, the proportion of NAS improvement and fibrosis responders was numerically greater with resmetirom compared with placebo

LDL-C, low-density lipoprotein cholesterol; NAFLD, nonalcoholic fatty liver disease; NAS, NAFLD activity score; NASH, nonalcoholic steatohepatitis.
