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.

MeasureTime frameDescription
Number of Participants with Adverse Events (AEs)Up to 99 DaysAn 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.
