What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

itacitinib (a drug taken as a tablet)

What this could lead to

If successful, this study could show that long-term itacitinib is safe and helps control symptoms of these chronic conditions.

What could go wrong

This is a small, early-phase rollover study (only 18 participants) with no placebo group, so results may not apply broadly. Side effects are possible, and it does not test a new treatment.

Conditions
