Study Summary

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of RO7303509 treatment in participants with systemic sclerosis (SSc) during a multiple-ascending-dose (MAD) portion of the trial. The MAD stage will consist of a treatment period of 12 weeks followed by either a safety follow-up period of 9 weeks or continued treatment in an optional open-label safety extension (OSE) stage of 52 weeks to assess the long-term safety.
