Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Body Mass Index (BMI) ≥ 18.0 to ≤ 32.0 kg/m^2 after rounding to the tenths decimal at the time of screening and upon initial confinement. BMI is calculated as weight in kg divided by the square of height measured in meters.
  • Body weight greater than 40 kg and less than 100 kg at screening and upon initial confinement.
  • A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile, and a 12-lead ECG

Exclusion criteria

  • Previous exposure to any anti-interleukin-12/23 or anti interleukin-23 treatment for at least one year prior to Screening.
  • Intention to perform strenuous exercise to which the participant is unaccustomed within one week prior to administration of first dose of study drug and during the study.

    AUCt of Risankizumab

  6. Area Under the Plasma Concentration-Time Curve (AUC) From Time 0 to Infinity (AUCinf) of Risankizumab

    Time frame: Up to approximately 141 days

  7. Number of Participants Experiencing Adverse Events

    Time frame: Up to approximately 141 days

    An adverse event is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment
