A Study to Investigate Whether the Immediate Use or Deferred Use of an Anti-viral Drug Lamivudine Will Help to Better Safe-guard the Delivery of Chemotherapy in Patients With Cancer Who Are Also Hepatitis B Carriers
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Patients with non-lymphoma and non-leukaemia cancer who are also hepatitis B carriers will have a risk of hepatitis B reactivation during chemotherapy. Lamivudine can be used effectively to control hepatitis upon reactivation during chemotherapy and the chemotherapy may not need to be interrupted. The study aims to investigate whether adding the anti-viral drug Lamivudine at the start of chemotherapy for all patients, rather than at the time of hepatitis reactivation for those with reactivation, will help to improve the delivery of chemotherapy in these patients.
