- Female participants INC#7: A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: o Is a WONCBP as defined in Section 10.4 (Appendix 4: Contraceptive and Barrier Guidance). OR o Is a WOCBP and using a contraceptive method that is highly effective, with a failure rate of <1%, as described in Section 10.4 (Appendix 4: Contraceptive and Barrier Guidance) during the study intervention period and for at least 4 months after the last dose of study intervention. The investigator should evaluate potential for contraceptive method failure (e.g., noncompliance, recently initiated) in relationship to the first dose of study intervention. A WOCBP must have a negative highly sensitive pregnancy test (urine or serum, as required by local regulations) within 24 hours before the first dose of study intervention. See Section 8.3.5. If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive. Additional requirements for pregnancy testing during and after study intervention are located in Section 8.3.5. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.

A positive TST or a positive (not indeterminate) interferon-gamma release assay (IGRA) TB test such as QuantiFERON-TB Gold Plus test is indicative, but not required for diagnosis of active TB. A positive TST is defined as a skin induration ≥5 mm at 48 to 72 hours (regardless of Bacillus Calmette-Guerin or other vaccination history).

Those with IGRA positive tests with documentation of the following may also be enrolled: o Successful completion of treatment for active TB o Completion of treatment for LTBI (with treatment as per local practice, for example: 3 months of isoniazid and rifampin or 4 months of rifampin or 3 months weekly isoniazid and rifapentine, or 9 months of isoniazid) o For those participants requiring Isoniazid (INH) therapy for latent TB, AST and ALT must be assessed following 3 weeks of INH treatment in screening. Participants will fail screening if ALT >2 × ULN is identified; these participants may be re-screened if ALT elevation resolves to ALT <2 × ULN during ongoing INH therapy following discussion with the medical monitor. • Those enrolled with positive IGRA or TST will be monitored during the study for new pulmonary symptoms (worsening cough, worse in intensity and productive) as well as fevers, night sweats or weight loss. Those reporting any of the above must be immediately evaluated by a physician for physical examination, imaging by chest x-ray or CT chest scan, laboratory evaluation of sputum (microscopy smear and culture for mycobacteria), and referral to TB specialist.

- Serologic evidence of Hepatitis B infection based on the results of testing for HBsAg, Anti-HBc and Anti-HBs as follows: EXC#35: • Patients positive for HBsAg are excluded. • Patients negative for HBsAg but positive for Anti-HBc, regardless of Anti-HBs antibody status, will require clarification of their status by testing for HBV DNA. o if HBV DNA is detectable, patients will be excluded from participation. o if HBV DNA is not detectable, patients will be eligible to enroll. NOTE: For those subjects included, additional ongoing assessment is required. Safety assessment for Hepatitis B during the trial will be as follows: • ALT, AST, HBsAg and HBV DNA will be tested approximately once a month for the first 6 months after initiation of study treatment, and approximately once every 3 months thereafter. • If HBsAg is positive or HBV DNA is detectable, study drug must be discontinued and the participant should be referred for a review by a liver specialist or hepatologist and consideration of hepatitis B treatment initiation. • If there is ALT/AST elevation greater than 2.5×ULN but repeat HBV DNA levels are nondetectable and HBsAg is negative, then investigate other causes for ALT/AST elevation. The suspected reason for ALT and/or AST elevation should be documented. • In case of Hepatitis B reactivation, follow local guidelines for treatment of Hepatitis B. "

NOTE: Stable non-cirrhotic chronic liver disease (including Gilbert’s syndrome, asymptomatic gallstones, and chronic stable hepatitis B or C) is acceptable if the participant otherwise meets entry criteria
- QTc >450 msec or QTc >480 msec for patients with bundle branch block NOTE: The QTc is the QT interval corrected for heart rate according to Bazett’s formula (QTcB), Fridericia’s formula (QTcF), and/or another method. It is either machine-read or manually over-read. The specific formula used to determine eligibility and discontinuation for an individual participant should be determined prior to initiation of the study and used throughout the study for the individual participant. In other words, several different formulas cannot be used to calculate the QTc for an individual participant and then the lowest QTc value used to include or discontinue the participant from the trial.
