What researchers measure

Primary outcomes

  1. Safety and tolerability of itacitinib as assessed by the changes in frequency and severity of adverse events, ECGs, vital signs, physical examinations, and clinical laboratory evaluations.

    Time frame: Approximately four months.

  2. Preliminary efficacy as assessed by the percentage of patients achieving ACR20 improvement from baseline on the day 28 and day 84 visits.

    Time frame: Approximately 84 days.

Secondary outcomes

  1. Preliminary Pharmacokinetic (PK) collections.

    Plasma concentrations of itacitinib will be used to estimate peak plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC).

    Time frame: Following 15 days of therapy.
