A late-breaking oral presentation will feature 96-week data from HARMONY, a Phase 2b study evaluating the efficacy and safety of EFX in patients with metabolic dysfunction-associated steatohepatitis (MASH), fibrosis stage 2 or 3 (F2–F3). The study met its primary endpoint of ≥1-stage improvement in fibrosis with no worsening of MASH after 24 weeks of treatment for both the 50 mg EFX (41%, p<0.05) and 28 mg EFX (39%, p<0.05) dose groups, compared to 20% for the placebo group. At Week 96, response rates for this endpoint increased to 75% (p<0.001) for 50 mg EFX and 46% (p=0.07) for 28 mg EFX, vs 24% for placebo.

The study also met additional histology endpoints at week 96. Notably 36% (p<0.01) and 31% (p<0.01) of patients treated with 50 mg EFX and 28 mg EFX, respectively, had a 2-stage improvement in fibrosis without worsening of MASH, more than 10-fold the placebo rate of 3%.
