Incidence of Hepatitis B Reactivation in Non-Hodgkin's Lymphoma Patients

Summary

This is a single-arm study. Key eligibility criteria include (1) newly diagnosed, diffuse large B-cell or follicular cell non-Hodgkin's lymphoma; (2) negative test for hepatitis B surface antigen (HBsAg) and positive for antibody to hepatitis B core antigen (anti-HBc); (3) adequate bone marrow, liver, and kidney function. All eligible patients will receive rituximab-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) chemotherapy according to current treatment guidelines. The primary endpoint of this study is the incidence of hepatitis B virus (HBV) reactivation, defined by a greater than 10-fold increase, compared with previous nadir levels, of HBV DNA during rituximab-CHOP chemotherapy and within 1 year after completion of the last course of rituximab-CHOP chemotherapy. Patients who have HBV reactivation during the study period will receive free entecavir treatment, one of the standard treatment for chronic hepatitis B, for 48 weeks. The secondary endpoints include the incidence of hepatitis flare, defined as a greater than 3 fold increase of serum alanine aminotransferase (ALT) level that exceeded 100 IU/L, and the efficacy and safety of rituximab-CHOP chemotherapy.

In the T1408 study we enrolled patients with newly diagnosed lymphoma who were HBsAg (-) and anti-HBc (+) and were to receive rituximab-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone)-based chemotherapy. Key findings of this study included (1) HBV reactivation, defined as a greater than 10-fold increase in HBV DNA compared with previous nadir levels, occurred to 10-20% of patients, depending on the sensitivity of the HBV DNA tests; (2) no HBV-related death with the prompt anti-viral therapy upon HBV reactivation; (3) patients with HBV reactivation were associated with poorer progression-free survival and overall survival; (4) serological breakthrough (i.e., re-appearance of HBsAg) is an important predictor of HBV-related hepatitis flare.

In this amendment we will enroll more patients to clarify the above findings: (1) the association between HBV reactivation and survival; (2) diagnostic value of quantitative HBsAg and anti HBc tests on HBV reactivation; (3) whether host factors (DNA polymorphism) may help predict HBV reactivation. A larger patient cohort is needed to identify (1) baseline features that may help predict HBV reactivation, and (2) on-treatment features that may help timely anti-viral therapy.
