Inclusion Criteria: * Participants must voluntarily sign and date an informed consent, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific procedures. * Body Mass Index (BMI) is \>= 18.0 to \<= 32 kg/m2 after rounding to the tenths decimal at screening. BMI is calculated as weight in kg divided by the square of height measured in meters. * A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead Electrocardiogram (ECG). Exclusion Criteria: * History of epilepsy, any clinically significant cardiac, respiratory (except mild asthma as a child), renal, hepatic, gastrointestinal, hematologic, endocrine, immunological, pulmonary, metabolic, neurological or psychiatric disease or disorder, or any uncontrolled medical illness. * History of any clinically significant sensitivity or allergy to any medication or food. * History of or active medical condition(s) or surgical procedure(s) that might affect gastrointestinal motility, pH, or absorption \[e.g., Crohn's disease, celiac disease, gastroparesis, short bowel syndrome, gastric surgery (except pyloromyotomy for pyloric stenosis during infancy), cholecystectomy, vagotomy, bowel resection, etc.\]. * Evidence of dysplasia or history of malignancy (including lymphoma and leukemia) other than successfully treated non-metastatic cutaneous squamous cell, basal cell carcinoma or localized carcinoma in situ of the cervix. * History or evidence of active Tuberculosis disease or latent Tuberculosis infection.

Primary outcome measure(s)

  • Number of Participants with Adverse Events (AEs) — Up to 99 Days
    An adverse event (AE) 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not the event is considered causally related to the use of the product.
  • Maximum Observed Serum Concentration (Cmax) of ABBV-859 — Up to 99 Days
    Cmax of ABBV-859
  • Time to Cmax (Tmax) of ABBV-859 — Up to 99 Days
    Time to Cmax (Tmax) of ABBV-859
  • Terminal Phase Elimination Rate Constant (Beta) of ABBV-859 — Up to 99 Days
    Beta of ABBV-859
  • Terminal Phase Elimination Half-Life (t1/2) of ABBV-859 — Up to 99 Days
    t1/2 of ABBV-859
  • Area Under the Plasma Concentration-Time Curve (AUC) From Time 0 to the Time of the Last Measurable Concentration (AUCt) of ABBV-859 — Up to 99 Days
    AUCt of ABBV-859
  • AUC From Time 0 to the Time Infinity (AUCinf) of ABBV-859 — Up to 99 Days
    AUCinf of ABBV-859
  • Apparent Clearance (CL/F) ABBV-859 — Up to 99 Days
