| NCT00805675 | Effects of Telbivudine and Tenofovir Disoproxil Fumarate Treatment on the Hepatitis B Virus DNA Kinetics in CHB | PHASE3 | COMPLETED | 83 | — | — | Nov 1, 2008 | - | Feb 28, 2012 | 1 | China |
Baseline HBV DNA is defined as the last pre-dose assessment of HBV DNA. Serum HBV DNA determinations were performed at a central laboratory through use of the COBAS TaqMan™ HBV DNA assay (Roche Molecular Systems, Pleasanton, CA, USA) which utilized the Real-time polymerase chain reaction (PCR) method and automated extraction by Cobas Ampliprep (threshold for detection 12 IU/mL). The Screening serum HBV DNA values must be ≥ 7 log10 copies/mL by COBAS TaqMan™ HBV DNA assay.
| Arm | Type | Description |
|---|---|---|
| Telbivudine 600 mg monotherapy | EXPERIMENTAL | All patients in this arm were randomized to receive Telbivudine (LDT) 600 mg QD. Patients were randomized prior to the first dose of study medication, which was defined as the study Baseline (Day 1) Visit. Subsequently, patients returned to the clinic at Days 2, 4, 6, 8, 11, 15 (Wk 2), 22 (Wk 3), 29 (Wk 4), 43 (Wk 6), 57 (Wk 8), and 85 (Wk 12) during the 12 weeks treatment phase. |
| Tenofovir disproxil fumarate 300 mg monotherapy | ACTIVE_COMPARATOR | All patients in this arm were randomized to receive Tenofovir disoproxil fumarate 300 mg(equivalent to tenofovir disoproxil 245 mg)QD. Patients were randomized prior to the first dose of study medication, which was defined as the study Baseline (Day 1) Visit. Subsequently, patients returned to the clinic at Days 2, 4, 6, 8, 11, 15 (Wk 2), 22 (Wk 3), 29 (Wk 4), 43 (Wk 6), 57 (Wk 8), and 85 (Wk 12) during the 12 weeks treatment phase. |
| Telbivudine 600 mg and Tenofovir 300 mg | ACTIVE_COMPARATOR | All patients in this arm were randomized to receive Telbivudine (LDT) 600 mg QD and Tenofovir (TDF) 300 mg (equivalent to Tenofovir disoproxil 245 mg)QD. Patients were randomized prior to the first dose of study medication, which was defined as the study Baseline (Day 1) Visit. Subsequently, patients returned to the clinic at Days 2, 4, 6, 8, 11, 15 (Wk 2), 22 (Wk 3), 29 (Wk 4), 43 (Wk 6), 57 (Wk 8), and 85 (Wk 12) during the 12 weeks treatment phase. |
