  15. Slide 15: Summary of ARGON-1 Study Efficacy

    Summary of ARGON-1 Study Efficacy Primary (ALT change) and key secondary (MRI-PDFF) endpoints were met at Week 12 • EDP-305 2.5mg achieved statistically significant ALT change - Mean reduction of ~28 U/L vs. 15 U/L in Placebo group (p<0.05) - Numerically higher reduction with 1mg (~22 U/L) vs. Place

  16. Slide 16: Summary of ARGON-1 Study Safety and Tolerability

    Summary of ARGON-1 Study Safety and Tolerability • EDP-305 regimens were generally safe in patients with NASH for up to 12 weeks with the majority of TEAEs being mild to moderate - The most common (≥5%) TEAEs included pruritus, GI related symptoms (nausea, vomiting, diarrhea), headache and dizziness
