Brief Summary:
This phase III trial studies the effect of tenofovir alafenamide in preventing liver complications in patients with current or past hepatitis B virus (HBV) who are receiving anti-cancer therapy for solid tumors. People with chronic or past HBV who are undergoing therapy for cancer are at an increased risk for changes in the liver which could be minor or severe. Tenofovir alafenamide is a drug that acts against infections caused by HBV and may help reduce the chance that HBV gets worse or comes back in patients receiving anti-cancer therapy for solid tumors.

Primary Outcome Measures :
- Time until adverse liver outcome, assessed by incidence of adverse liver outcome [ Time Frame: From the start of study treatment up to 24 months ]Graded according to Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 4.0. Adverse liver outcome defined as liver-related death or liver failure (ascites, hepatic encephalopathy or impaired hepatic synthetic function defined as total bilirubin >= 5 mg/dL or international normalized ration [INR] >= 2.0) not due to disease progression in the liver. The study will recruit patients with multiple different cancer types, but predominantly lung, breast, colon, prostate, gynecological, and head and neck cancers. Estimates of adverse liver outcomes at 1 year will be derived using cumulative incidence to account for the competing risk of death. The final analysis will rely on Cox regression, adjusting for the stratification factors.
Secondary Outcome Measures :
- Incidence of hepatitis B Virus (HBV) reactivation among patients with solid malignancies and chronic or past HBV infection during or after completion of anti-cancer therapy [ Time Frame: Up to 24 months ]Estimates of HBV reactivation at one year will be derived using cumulative incidence to account for competing risks. Under this scenario, a sample size of n=222 patients for each randomized study will allow the investigators to estimate the confidence interval to within +/- 6% (based on the upper bound of the 95% confidence interval using an exact binomial in patients with complete follow-up), if the assumed incidence is at least 20%. Thus, this sample size will allow the confidence interval to be estimated to within +/- 31.1% of the assumed incidence (the "relative accuracy", defined as: (95% confidence interval [CI] upper bound - p)/p], where p is the assumed incidence).
- HBV reactivation rate [ Time Frame: Up to 24 months ]The investigators will compare HBV reactivation rates by arm within each randomized trial. Based on a two-sample survival design accounting for the competing risk of death (~20% deaths at 1 year [hazard rate of 0.223]), and a one-sided alpha=0.05 test, then n=222 patients (111 per arm) will give 81% power to detect a hazard ratio for HBV reactivation for experimental to standard arms of 0.47, representing a 53% reduction in the hazard risk of HBV reactivation in the first year (from a hazard=0.223 down to hazard = 0.105), or an absolute reduction of 50% (from 20% down to 10%). Multivariable Cox regression will compare the effect of intervention assignment, adjusting for the stratification factors specified in the main clinical study.
- Hepatitis flare [ Time Frame: Up to 24 months ]Defined as alanine aminotransferase (ALT) > 3 x baseline and > 100 U/L.
- Initiation of upon indication tenofovir alafenamide (TAF) therapy [ Time Frame: Up to 24 months ]
- Cancer therapy interruption [ Time Frame: Up to 24 months ]Defined as dose reduction, treatment delay, or termination of anti-cancer therapy due to hepatic-related reasons other than disease progression in the liver.
- Death due to any cause [ Time Frame: From date of randomization up to 24 months ]
