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.

Condition Intervention Phase
Colorectal Neoplasms
Drug: Entecavir
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: An Open, Randomized Controlled Clinical Trial to Compare the Prophylactic Use or Preemptive Use of an Anti-viral Drug Entecavir in Patients With Colorectal Cancer Who Are Inactive Hepatitis B Carriers

Primary Outcome Measures:
  • Incidence of hepatitis B virus associated hepatitis [ Time Frame: through study completion, an average of 1 year ] [ Designated as safety issue: Yes ]
    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:
  • Incidence of hepatitis B virus reactivation [ Time Frame: through study completion, an average of 1 year ] [ Designated as safety issue: Yes ]
    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 hepatitis [ Time Frame: through study completion, an average of 1 year ] [ Designated as safety issue: Yes ]
    Chemotherapy disruption is defined as either premature termination or a delay of at least 7 days between chemotherapy cycles.

Estimated Enrollment: 50
Study Start Date: May 2015
Estimated Study Completion Date: May 2018
Estimated Primary Completion Date: May 2017 (Final data collection date for primary outcome measure)
