What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are BMS-986528. The registry lists allocation as randomized. This study wants to measure the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and the preliminary evidence of disease-modifying effect of BMS-986528 in participants with refractory, difficult-to-treat rheumatoid arthritis (RA).
They plan to enroll about 84 people at 39 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
