\- Patients without a history of AIDS-defining opportunistic infections within the past 12 months.
- Patients with Hepatitis B (HBV): chronic carriers of HBV infection (HBsAg-positive) or individuals who have serologic evidence of a resolved prior HBV infection (i.e., HBsAg-negative and anti-HBc-positive) are eligible if they are receiving appropriate suppressive antiviral therapy that does not include medications known to alter metabolism or tolerability of component drugs in the protocol treatment (see Appendix) prior to initiation of cancer therapy, and liver function tests meet study eligibility criteria.
- Patients with Hepatitis C (HCV): patients with a history of HCV infection who have completed curative antiviral treatment are eligible if the HCV RNA viral load is below the limit of quantification within 90 days of study enrollment. Patients on concurrent HCV treatment must have HCV RNA viral load below the limit of quantification within 30 days of study enrollment. Patients must also meet liver function test eligibility requirements and antiviral therapy does not include medications known to alter metabolism or tolerability of component drugs in the protocol treatment
