Official Title: A Phase 2, Double-blind, Randomized, Placebo-controlled Multicenter Study to Evaluate Safety, Tolerability, Efficacy, and Pharmacokinetics of JBT-101 in Diffuse Cutaneous Systemi

Brief Summary: The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and efficacy of JBT-101 in adult subjects with diffuse cutaneous systemic sclerosis.

Detailed Summary:

Part A of the study is an interventional, double-blind, randomized, placebo-control design will be used to test safety, tolerability, pharmacokinetics, and efficacy of JBT-101 in subjects ≥ 18 and ≤ 70 years of age with active diffuse cutaneous systemic sclerosis. The screening period is up to 28 days, with 84 days treatment period and 28 days follow-up off active treatment.

Part B of the study is an interventional, open-label design will be used. All subjects who complete dosing in Part A without permanent discontinuation of study drug and who pass repeat safety screening will be eligible for enrollment. The screening period is up to 28 days, with a 364 day treatment period and 28 day follow up after last dose of JBT-101.
