Confirmed positive test for hepatitis B serology for:

1. Hepatitis B surface antigen, OR

2. Hepatitis B core antibody (HBcAb) AND hepatitis B virus (HBV) DNA detected above the lower limit of quantitation Note: Patients who were HBcAb positive at screening were tested every 3 months for HBV DNA. To remain eligible for the study, the patient's HBV DNA levels must have remained below the limit of quantitation

   • Positive test for hepatitis C antibody

   • Any of the following:

     1. Clinically significant chronic infection (ie, osteomyelitis, bronchiectasis, etc) within 8 weeks prior to Inclusion Visit (chronic nail infections not causing open skin lesions are allowed)

   • Any infection requiring IV or oral anti-infectives (including antivirals) within 2 weeks prior to Inclusion visit

   • Have evidence of active TB or latent TB:

     1. have evidence of active TB, defined in this study as the following: Documented by a positive PPD test (≥5 mm induration between approximately 48 and 72 hours after application, regardless of vaccination history), medical history, clinical features, and abnormal chest x-ray at screening. The QuantiFERON®-TB Gold test or TSPOT®.TB test (as available and if compliant with local TB guidelines) may be used instead of the PPD test. Patients are excluded from the study if the test is not negative and there is clinical evidence of active TB.

        Exception: Patients with a history of active TB who have documented evidence of appropriate treatment, have no history of re-exposure since their treatment was completed, and have a screening chest x-ray with no evidence of active TB may be enrolled if other entry criteria are met. Such patients would not be required to undergo the protocol-specific TB testing for PPD, QuantiFERON®-TB Gold test, or T-SPOT® TB test but must have a chest x-ray at screening.

     2. have evidence of untreated/inadequately or inappropriately treated latent TB, defined in this study as the following: documented to have a positive PPD test (≥5 mm induration between approximately 48 and 72 hours after application, regardless of vaccination history), no clinical features consistent with active TB, and a chest x-ray with no evidence of active TB at screening; or PPD test is positive and the patient has no medical history or chest x-ray findings consistent with active TB, the patient may have a QuantiFERON®-TB Gold test or TSPOT® TB test (as available and if compliant with local TB guidelines). If the test results are not negative, the patient will be considered to have latent TB (for purposes of this study); or QuantiFERON®-TB Gold test or T-SPOT® TB test (as available and if compliant with local TB guidelines) may be used instead of the PPD test. If the test results are positive, the patient will be considered to have latent TB. If the test is not negative, the test may be repeated once within approximately 2 weeks of the initial value. If the repeat test results are again not negative, the patient will be considered to have latent TB (for purposes of this study). Exception: Patients who have evidence of latent TB may be enrolled if he or she completes at least 4 weeks of appropriate treatment prior to randomization and agrees to complete the remainder of treatment while in the trial.

Exception: Patients with a history of latent TB who have documented evidence of appropriate treatment, have no history of re-exposure since their treatment was completed, and have a screening chest x-ray with no evidence of active TB may be enrolled if other entry criteria are met.

Such patients would not be required to undergo the protocol specific TB testing for PPD, QuantiFERON®-TB Gold test, or TSPOT® TB test but must have a chest x-ray at screening.
