Prophylactic or Preemptive Entecavir in Patients With Gastrointestinal Cancer Who Are Inactive Hepatitis B Carriers

Официальное название

An Open, Multicentre, Phase 3, Randomized Controlled Clinical Trial to Compare the Prophylactic Use or Preemptive Use of an Anti-viral Drug Entecavir in Patients With Gastrointestinal Cancer Who Are Inactive Hepatitis B Carriers

Обзор

There has been no report on whether the patients with gastrointestinal cancer who are also inactive hepatitis B carriers should receive prophylactic use or preemptive use of an anti-viral drug entecavir during anti-tumor therapy. This open, multicentre, phase 3, randomized controlled clinical trial aims to compare the impact of the prophylactic use or preemptive use of an anti-viral drug entecavir on the outcomes of patients with gastrointestinal cancer who are also inactive hepatitis B carriers during chemotherapy or immunotherapy and the subsequent follow-ups, including two cohorts of chemotherapy and immunotherapy.

Подробное описание

Patients with gastrointestinal cancer who are also inactive hepatitis B carriers are enrolled and randomized into two groups as following. Patients in experimental group are treated with entecavir prophylactically in the dose of 0.5mg p.o. every day from the initiation of chemotherapy or immunotherapy till 6 months after the end of chemotherapy or immunotherapy. Patients in active comparator group are only treated with entecavir in the dose of 0.5mg p.o. every day from the time that the DNA copies of hepatitis B virus become positive till 6 months after the end of chemotherapy or immunotherapy.
