Conditions

MASH

Brief summary

The purpose of this study is to assess the safety, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity and activity of RO7790121 in participants with advanced metabolic dysfunction-associated steatohepatitis (MASH) fibrosis.

Interventions

Participants will be administered RO7790121 via IV infusion on Day 1, and Weeks 2, 6 and 10. Participants will then be administered RO7790121 SC injections every four weeks (Q4W) from week 14 up to and including Week 50.
