Conditions

Rhematoid Arthritis

Brief summary

This is a Phase 1, first in human study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending doses of JADE201 compared to placebo in participants with Rheumatoid Arthritis

Detailed description

This is a multisite, Phase 1, double-blind, placebo-controlled, randomized, first-in-human (FIH), single ascending dose study evaluating the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of JADE201 in participants with Rheumatoid Arthritis. Approximately 36 evaluable participants (6 in each cohort) will be enrolled. JADE201 will be administered by a subcutaneous injection. The results of this study will form the foundation for subsequent clinical development of JADE201 in autoimmune indications.
