Arms and Interventions

Arm Intervention/treatment
Experimental: ROADMAP Group (Group I)

Patients were to take telbivudine 600 mg orally daily from Baseline.At Week 24, patients in Group I were split into Group I-A or Group I-B based on their virologic load:

  • Group I-A: This group of patients was those with HBV DNA ≥300 copies/mL at Week 24 and adefovir was to be added at Week 28;
  • Group I-B: This group of patients was those with HBV DNA <300 copies/mL at Week 24. Telbivudine monotherapy was to be continued until there was a viral breakthrough (confirmed by two examinations with at least 1 month interval with compliance factor excluded) and then adefovir was to be added;

The total treatment duration was 104 weeks.

Drug: telbivudine
telbivudine, 600mg, oral, daily
Other Name: Sebivo®
Active Comparator: SOC (Standard of Care) Group (Group II)
patients were to take telbivudine 600 mg monotherapy from Baseline until Week 104. If viral breakthrough (defined as HBV DNA 1 log10 above nadir) was confirmed (by two examinations with at least a 1 month interval with compliance factor excluded), adefovir 10 mg daily was to be added.
Drug: telbivudine

Other Name: Sebivo®

Outcome Measures

Primary Outcome Measures :
  1. To demonstrate the percentage of patients achieving HBV DNA< 300copies/mL at Week 104 in Group I is superior than that in Group II [ Time Frame: Week 104 ]

Secondary Outcome Measures :
  1. Percentage of patients achieving HBV DNA <60IU/mL (300copies/mL) at Week 52 [ Time Frame: week 52 ]
  2. Serum HBV DNA reduction from baseline at week 104 [ Time Frame: week 104 ]
  3. Percentage of patients with HBeAg loss & HBeAg seroconversion at week104 in patients with HBeAg positive at baseline [ Time Frame: week 104 ]
  4. Percentage of patients with HBV DNA<300copies/mL AND HBeAg loss or seroconversion at Week 104 in patients with positive HBeAg at baseline [ Time Frame: week 104 ]
  5. Serum HBV DNA reduction from baseline at week 52 [ Time Frame: week 52 ]
