Brief summary
In this study, we will evaluate the incidence of hepatitis B virus reactivation within the first 6 months of treatment with rituximab, standard chemotherapy and TAF in patients with diffuse Large B-Cell Lymphoma/Chronic Lymphoid Leukemia HBsAg-positive.
Detailed description
This is a prospective, multicenter, interventional, single arm, evaluating the incidence of hepatitis B virus (HBV) reactivation within the first 6 months treatment period in HBsAg positive patients treated for DLBCL/Chronic Lymphoid Leukemia with Rituximab, standard chemotherapy, and TAF. Approximate duration of the recruitment period based on the number of patients available The duration of the recruitment period has been estimated at 12 months. Patients will receive Rituximab+Chemotherapy+TAF for 6 months, followed by TAF as monotherapy for further 12 months. All subjects will receive TAF 1-3 weeks before Rituximab+Chemotherapy and withdrawn 12 months after the completion of chemotherapy. Then patients will be also observed for further12 months
Interventions
DRUGRituximab
Patients will receive Rituximab+Chemotherapy+TAF for 6 months, followed by TAF as monotherapy for further 12 months. All subjects will receive TAF 1-3 weeks before Rituximab+Chemotherapy and withdrawn 12 months after the completion of chemotherapy.
DRUGChemotherapy
Patients will receive Rituximab+Chemotherapy+TAF for 6 months, followed by TAF as monotherapy for further 12 months. All subjects will receive TAF 1-3 weeks before Rituximab+Chemotherapy and withdrawn 12 months after the completion of chemotherapy.
DRUGTenofovir alafenamide
Patients will receive Rituximab+Chemotherapy+TAF for 6 months, followed by TAF as monotherapy for further 12 months. All subjects will receive TAF 1-3 weeks before Rituximab+Chemotherapy and withdrawn 12 months after the completion of chemotherapy.

Inclusion criteria

(inactive carriers). * No previous treatment with antiviral drugs for HBV infection. * Patients with satisfactory renal function.
Exclusion criteria
* Hepatic insufficiency for any reason * History of other liver diseases such as hepatitis C, D, autoimmune hepatitis, primary biliary cirrhosis, Wilsons' disease * Positive viral markers, such as IgM antibody to hepatitis A virus, hepatitis C virus, IgG antibody to hepatitis D virus, IgM antibody to hepatitis E virus, or antibody to HIV * Pregnant or breastfeeding women * Other major systemic diseases, such as active infection, significant cardiac disease, neurological deficit or psychiatric disorder, that the investigators consider being a significant risk * Patients with moderate or severe renal failure. * Intolerance to any of the components of the therapeutic regimen. Treatment with any investigational medicinal product (unapproved) in the last 30 days. * Any other disorder that, in the investigator's opinion, makes the patient ineligible for recruitment or that could interfere in his/her participation or in the conclusion of the study.
