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

Phase 2
Conditions
Colorectal Neoplasms
Interventions
Registration Number
NCT02777814
Lead Sponsor
Sun Yat-sen University
Brief Summary

There has been no report on whether the patients with colorectal 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 colorectal cancer who are also inactive hepatitis B carriers during chemotherapy and the subsequent follow-ups.

Study Design
PARALLEL
Arm && Interventions
GroupInterventionDescription
Prophylactic EntecavirEntecavirEntecavir is prophylactically used from the time of chemotherapy initiation at the dose of 0.5 mg p.o daily
Preemptive EntecavirEntecavirEntecavir is preemptively used from the time that hepatitis B virus DNA copies are more than 100 IU/ml at the dose of 0.5 mg p.o daily
Primary Outcome Measures
NameTimeMethod
Incidence of hepatitis B virus associated hepatitisthrough study completion, an average of 1 year

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

Secondary Outcome Measures
NameTimeMethod
Incidence of hepatitis B virus reactivationthrough study completion, an average of 1 year

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.

Interruption of chemotherapy due to hepatitisthrough study completion, an average of 1 year

Chemotherapy disruption is defined as either premature termination or a delay of at least 7 days between chemotherapy cycles.
