What researchers measure

Primary outcomes

  1. Maximum Plasma Concentration (Cmax)

    It is defined as the maximum observed plasma concentration (Cmax) for upadacitinib.

    Time frame: Up to 7 days

  2. Time to Maximum Observed Plasma Concentration (Tmax)

    It is defined as the time to maximum plasma concentration (Tmax) of upadacitinib.

    Time frame: Up to 7 days

  3. Area under the plasma concentration-time curve within a dosing interval (AUCtau)

    The area under the plasma concentration-time curve (AUCtau) is a method of measurement of the total exposure of a drug in plasma.

    Time frame: Up to 7 days

  4. Oral Clearance

    Clearance is defined the volume of plasma cleared of the drug per unit time.

    Time frame: Up to 7 days

  5. Number of Participants With Treatment Emergent Adverse Events (TEAE)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug as either probably related, possibly related, probably not related or not related. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events (TEAEs) are defined as any event that began or worsened in severity after the first dose of study drug.

    Time frame: Up to 2 years
