Clinical Trial Summary

There has been no report on whether the patients with gastric cancer who are also inactive Hepatitis B carriers should receive prophylactic use or preemptive Use of an Anti-viral Drug Entecavir. This open, 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 gastric cancer who are also inactive hepatitis B carriers during chemotherapy and the subsequent follow-ups.

Description:

Patients with gastric 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 till 6 months after the end of chemotherapy.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 are more than 100 IU/ml till 6 months after the end of chemotherapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of hepatitis B virus associated hepatitis	Hepatitis is defined as a 3-fold or greater increase in the serum ALT level that exceeded the reference range (>58U/L) or an absolute increase in the level of ALT of greater than 100 U/L compared with the baseline level	through study completion, an average of 1 year
Secondary	The incidence of hepatitis B virus reactivation	Reactivation of HBV is defined as a 10-fold or greater increase in the HBV DNA level or an absolute increase of 10^5 copies/mL or greater compared with the baseline value.	through study completion, an average of 1 year
Secondary	Interruption of chemotherapy due to hepatitis	Chemotherapy disruption is defined as either premature termination or a delay of at least 7 days between chemotherapy cycles.	through study completion, an average of 1 year
