Background/Aim: To evaluate amino acid changes within HBV pol/RT after 96 weeks of treatment with TDF or FTC/ TDF and determine their potential association with TDF resistance. Methods: In Study GS-US-174-0121, 280 patients receiving lamivudine (LAM) with detectable LAM-resistance mutations in HBV pol/RT (LAM-R: rtM204V/I±rtL180M) were randomized 1:1 to receive blinded treatment with TDF or FTC/TDF for 96 weeks. Virologic breakthrough (VB) was defined as confirmed HBV DNA >1 log10 increase from nadir or HBV DNA ≥400 copies/mL (69 IU/mL) after <400 copies/mL. Resistance genotyping by HBV pol/RT sequencing was attempted for all patients at baseline and if viremic (HBV DNA ≥400 copies/ mL) at Week 96/study discontinuation. Results: Overall, 18 patients (9 TDF, 9 FTC/TDF) were viremic viremic at Week 96/last visit. The mean baseline HBV DNA was significantly higher for viremic patients (8.04 log10 copies/mL) compared to patients who did not qualify for genotyping (6.39 log10 copies/mL). In the TDF arm, 3 patients had conserved site changes/reversions (1 with VB), 1 had unique polymorphic site changes, 2 had no change, and 3 were unable to be genotyped. In the FTC/TDF arm, 2 patients had conserved site changes/reversions, 1 had unique polymorphic site changes, 4 had no change, and 2 were unable to be genotyped. No phenotypic resistance to TDF was observed. Four of eight (50%) patients had LAM-R reversions (rtV/I204M±rtM180L) on TDF while 1/8 (12.5%) patients on FTC/TDF had LAM-R reversions. Thirteen patients (4.6%) with prior entecavir (ETV) exposure and 25 patients (8.9%) with baseline ETV-R were enrolled; neither had an impact on viral kinetics. Conclusions: No TDF resistance has been detected through 96 weeks of treatment with either TDF or FTC/TDF in LAM-R patients. The presence of ETV-R or ETV exposure did not impact viral kinetics through 96 weeks. Resistance surveillance in this population will continue through Year 5.

Background: Efficacy and safety of tenofovir DF (TDF) have been demonstrated over 6 years in pivotal HBV studies, but have yet to be established in lamivudine-resistant (LAM-R) patients in a prospective, randomized trial. Methods: Phase 3b, double-blind, randomized (1:1) comparison of TDF and emtricitabine (FTC)/TDF in chronic HBV patients on LAM at screening with HBV DNA ≥103 IU/mL and documented LAM-R (rtM204V/I±rtL180M; INNO-LiPA HBV v2/ v3). Patients were stratified by ALT (≥ or <2×ULN) and HBeAg status. Efficacy and safety, including bone mineral density (BMD) monitoring by DXA were assessed over 96 weeks. Results: Of 280 randomized and treated patients, 133/141 (94%) and 125/139 (90%) in TDF and FTC/TDF groups completed 96 weeks. Groups were well matched: mean age 47 years, 75% males, 34% Asian, 47% HBeAg+, 42% ALT <ULN; HBV genotypes: 22% A, 14% B, 19% C, and 45% D. By ITT analysis, missing=failure, 89% and 86% receiving TDF and FTC/TDF, respectively, had HBV DNA <400 copies/mL at Week 96 (P =0.43); 70% in each arm had normal ALT. HBeAg loss was observed in 10/65 (15%) and 9/68 (13%) in TDF and FTC/TDF arms, respectively. One patient (FTC/TDF) had HBsAg loss without seroconversion. Both treatments were well tolerated with 1% (3/280) discontinuing for adverse event (1 TDF, 2 FTC/TDF). No patients had confirmed increase in serum creatinine of ≥0.5 mg/dL, and 1% (2 TDF) had serum phosphorus <2 mg/dL. BMD of spine and hip revealed no clinically relevant bone loss, and there were no non-traumatic fractures reported. No TDF resistance was detected through 96 weeks. Conclusions: A high rate of HBV DNA suppression with no detectable TDF resistance was achieved with TDF monotherapy in LAM?R patients through 96 weeks. TDF was safe and well tolerated, with a low rate of renal events and no evidence of clinically relevant bone loss.
