• Males must be willing to abstain from sperm donation while on study through 2 weeks after receiving the (last [multiple dose studies]) dose of study drug.

• Females must be of non-reproductive potential (ie, postmenopausal - age ≥ 55 years with cessation of menses for 12 months or more, or according to the definition of "postmenopausal range" for the laboratory involved OR history of hysterectomy; OR history of bilateral oophorectomy).

Exclusion criteria

• Positive Hepatitis B Surface Antigen (HepBsAg) (indicative of chronic Hepatitis B) or detectable Hepatitis C virus Ribonucleic acid (RNA) by Polymerase Chain Reaction (PCR) (indicative of active Hepatitis C - screening is generally done by Hepatitis C Antibody (HepCAb), followed by Hepatitis C virus RNA by PCR if HepCAb is positive).
• Positive results for Human Immunodeficiency Virus (HIV).
• Participant has a history of residential exposure to tuberculosis without a documented history of prophylactic treatment of tuberculosis or participant has a positive purified protein derivative (PPD) or QuantiFERON or T-Spot test at Screening. Participants with a documented negative PPD or QuantiFERON or T-Spot test within 4 weeks prior to screening who have no known tuberculosis exposure and have not traveled to an area with tuberculosis do not need to have a test performed at screening.
• Currently receiving treatment in another investigational device or drug study, or less than 30 days or less than 5 half-lives, whichever is longer, since ending treatment on another investigational device or drug study.
• Malignancy except non-melanoma skin cancers, cervical or breast ductal carcinoma in situ within the last 5 years.
• Any active infection for which systemic anti-infectives were used within 4 weeks prior to Day 1.
• Females who are lactating/breastfeeding or who plan to breastfeed while on study through 2 weeks after receiving the dose of study drug.
• Female participants with a positive pregnancy test.
• Males with partners who are pregnant or planning to become pregnant while the participant is on study through 2 weeks after receiving the dose of study drug.
