A Two-part, Phase 1/2, Randomized, Double-blind, Placebo-controlled, Single-ascending-dose Study of PRO-203 in Healthy Adult Volunteers Followed by an Open-label, Single-ascending-dose With Priming Study of PRO-203 in Participants With Systemic Sclerosis

Detailní popis
This two-part study is designed to characterize the first-in-human safety, tolerability, PK, and PD profile of PRO-203 across ascending dose levels.
Part 1 - Healthy Volunteers (HV) Part 1 enrollment is complete and has enrolled 20 healthy volunteers across 3 cohorts. Participants within each cohort received a single SC dose of PRO-203 or matching placebo. Part 1 has completed enrollment.
Part 2 - Systemic Sclerosis (SSc) Up to 24 participants with SSc will be enrolled in multiple cohorts (with optional additional cohorts) Participants within each cohort will receive a single SC cycle of PRO-203. Part 2 includes a Main Study and an optional Long-term Extension (LTE). In the LTE, eligible participants may receive retreatment if they meet retreatment criteria. Total study duration per participant is up to 53 weeks.
