Brief summary
The main aim of this study is to find out how zasocitinib (TAK-279) interacts with other medicines taken by mouth (orally). This will be examined by how the body processes medicines, which is called pharmacokinetics or PK. In this study, other medicines that will be administered together with zasocitinib include a contraceptive (levonorgestrel (LNG) and ethinyl estradiol \[EE\]), a medicine for diabetes (metformin), a medicine used for heart problems (digoxin), and a medicine that blocks the production of stomach acid (esomeprazole). Another aim is to learn about the side effects of zasocitinib and how well it is tolerated when taken alone and together with these other medicines. During the study, participants will need to stay at the clinic for up to 27 days.
Detailed description
The drug being tested in this study is called zasocitinib. Zasocitinib is being tested to assess the effect of zasocitinib on the pharmacokinetics of Combined Oral Contraceptive (COC \[containing LNG and EE\] in Part 1), multidrug and toxic compound extrusion (MATE) substrate (metformin in Part 2), and a P-glycoprotein (P-gp) substrate (digoxin in Part 3). Additionally, the effect of proton-pump inhibitor (PPI) (esomeprazole in Part 4) on the pharmacokinetics of zasocitinib is being evaluated in healthy participants. The study will enroll approximately 78 participants. Participants will be enrolled in one of the four parts to evaluate the following treatments: * Part 1: COC (LNG and EE) + Zasocitinib * Part 2: Metformin + Zasocitinib * Part 3: Digoxin + Zasocitinib * Part 4: Zasocitinib + Esomeprazole The overall time (including screening and follow-up periods) to participate is approximately 68 days for Part 1, 54 days for Part 2, 62 days for Part 3 and 56 days for Part 4. All participants will be followed up for up to 14 days after the last dose of Period 2 in each Part.

Inclusion criteria
1. Body mass index (BMI) greater than or equal to (\>=) 18.0 and less than or equal to (\<=) 32.0 kilograms per square meter (kg/m\^2) at the screening visit. 2. Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs, and Electrocardiograms (ECGs) as outlined in the protocol. Part 1 Only: 3. Healthy, adult, female, aged 18 to 65 years, inclusive, at the screening visit. Parts 2-4 Only: 4. Healthy, adult, male or female, aged 18 to 55 years, inclusive, at the screening visit.
Exclusion criteria
1. Positive urine drug or alcohol results at the screening visit or at check-in. 2. Unable to refrain from or anticipates the use of: * Any drugs, including prescription and non-prescription medications, herbal remedies, or vitamin supplements and other drugs outlined in protocol. * Any drugs known to be inducers of Cytochrome P450 3A4 (CYP3A4) and/or P-gp, including St. John's Wort, for 28 days prior to the first dosing. 3. Has been on a diet incompatible with the on-trial diet, in the opinion of the investigator or designee, within the 30 days prior to first dosing and throughout the trial. 4.
