| Description | Tenofovir Disoproxil Fumarate is a nucleotide reverse transcriptase inhibitor to treat HIV and chronic Hepatitis B.In Vitro:Tenofovir shows cytotoxic effects on cell viability in HK-2 cells, with IC50 values of 9.21 and 2.77 μM at 48 and 72 h in MTT assay, respectively. Tenofovir diminishes ATP levels in HK-2 cells. Tenofovir (3.0 to 28.8 μM) increases oxidative stress and protein carbonylation in HK-2 cells. Furthermore, Tenofovir induces apoptosis in HK-2 cells, and that apoptosis is induced via mitochondrial damage[1]. Tenofovir and M48U1 formulated in 0.25% HEC each inhibits the replication of both R5-tropic HIV-1BaL and X4-tropic HIV-1IIIb in activated PBMCs, and inhibits several laboratory strains and patient-derived HIV-1 isolates. The combined formulation of M48U1 and tenofovir in 0.25% HEC exhibits synergistic antiretroviral activity against infection with R5-tropic HIV-1BaL, and is not toxic to PBMCs[2].In Vivo:Tenofovir Disoproxil Fumarate (20, 50, 140, or 300 mg/kg) administered to BLT mice, shows dose dependent activity during vaginal HIV challenge in BLT humanized mice. Tenofovir Disoproxil Fumarate (50, 140, 300 mg/kg) significantly reduces HIV transmission in BLT mice[3]. Tenofovir Disoproxil Fumarate (0.5, 1.5, or 5.0 mg/kg/day, p.o.) induces a dose-dependent decline in serum viremia in woodchucks chronically infected with WHV. Tenofovir Disoproxil Fumarate administration is safe and effective in the woodchuck model of chronic HBV infection[4]. References: | |||||

Tenofovir disoproxil fumarate is a nucleotide reverse transcriptase inhibitor that inhibits the replication of human immunodeficiency virus (HIV) in MT-2 cells and PBMC with the half maximal effective concentration EC50 values of 0.007 μmol/L and 0.005 μmol/L [1].
Shortly upon administration, tenofovir disoproxil fumarate rapidly goes through esterase hydrolysis removing the two ester groups and yielding tenofovir, which is a nucleotide analogue with anti-viral activity against retroviruses including HIV-1, HIV-2 and hepadnaviruses. Tenofovir is phosphorylated by cellular nucleotide kinase and adenylate kinase and eventually converted into its active anabolite tenofovir diphosphate, which inhibits HIV-1 reverse transcriptase and terminates the growing DNA chain [2].

Bone mineral density reductions after tenofovir disoproxil fumarate initiation and changes in phosphaturia: a secondary analysis of ACTG A5224s.[Pubmed:28369419]
J Antimicrob Chemother. 2017 Jul 1;72(7):2042-2048.
Background: It is unknown if the greater reductions in bone mineral density (BMD) associated with initiation of Tenofovir Disoproxil Fumarate compared with abacavir in previously untreated HIV-infected participants in the ACTG A5224s clinical trial were associated with potentially worsening tenofovir-related phosphaturia. Methods: We correlated changes in BMD at the hip and spine with changes in phosphaturia [transtubular reabsorption of phosphorus (TRP) and tubular maximum phosphate reabsorption per glomerular filtration rate (TmP/GFR)] from entry through week 96 in those initiating tenofovir ( n = 134) versus abacavir ( n = 135) with efavirenz or atazanavir/ritonavir in A5224s. We also correlated changes in BMD with tenofovir AUC measured between weeks 4 and 24. Results: Changes in TRP and TmP/GFR through week 96 between the tenofovir and abacavir arms were not significantly different (both P >/= 0.70) and did not differ with use of efavirenz versus atazanavir/ritonavir. There were no significant correlations between changes in either TRP or TmP/GFR and with either hip or spine BMD in the tenofovir arms. Tenofovir AUC was significantly correlated with changes in hip BMD, but not spine BMD, at week 24 ( r = -0.22, P = 0.028) and week 48 ( r = -0.26, P = 0.010), but not at week 96 ( r = -0.14, P = 0.18). Conclusions: Changes in phosphaturia were not different between the tenofovir and abacavir arms in A5224s. Changes in hip and spine BMD with tenofovir were not related to changes in phosphaturia. However, tenofovir exposure was weakly associated with changes in hip BMD through week 48.
Liver fibrosis regression and progression during controlled hepatitis B virus infection among HIV-HBV patients treated with tenofovir disoproxil fumarate in France: a prospective cohort study.[Pubmed:28362068]
J Int AIDS Soc. 2017 Feb 28;20(1):21426.
INTRODUCTION: Long-term Tenofovir Disoproxil Fumarate (TDF) use has been associated with significant regression of liver fibrosis during hepatitis B virus (HBV) mono-infection, yet little is known during HIV-HBV coinfection. The aim of this study was to evaluate the evolution of liver fibrosis and its determinants in TDF-treated coinfected patients. METHODS: In this prospective cohort study, 167 HIV-HBV-infected patients initiating TDF-containing antiretroviral therapy were included. Fibrosis was assessed using the FibroTest(R) at baseline and every six to twelve months. Risk factors for fibrosis progression (F0-F1-F2 to F3-F4) and regression (F3-F4 to F0-F1-F2) were evaluated. RESULTS: At baseline, 134 (80.2%) patients had detectable HBV-DNA (median = 4.93 log10 IU/mL, IQR = 2.94-7.15) and 104 (62.3%) had hepatitis B "e" antigen-positive serology. Median follow-up was sixty months (IQR = 36-93). In the 47 (28.1%) patients with F3-F4 baseline fibrosis, 7/47 (14.9%) regressed to F0-F1-F2 at last follow-up visit. Fibrosis regression was significantly associated with higher CD4+ cell counts (P = 0.009) and lower fasting triglyceride levels (P = 0.007) at TDF-initiation. In the 120 (71.9%) patients with F0-F1-F2-baseline fibrosis, 20/120 (16.7%) progressed to F3-F4 at last follow-up visit. Fibrosis progression was associated with male gender (P = 0.01), older age (P = 0.001), from low/moderate HBV-endemic country (P = 0.007), lower nadir CD4+ cell count (P = 0.03), higher fasting glycaemia (P = 0.03) and anaemia (P = 0.004) at TDF-initiation. Control of HBV replication at end of follow-up was extensive (88.1%), while no HBV-related factors emerged as predictors of progression/regression. Incidence of severe liver-related events was low (n = 4, rate = 0.5/100 person-years). CONCLUSION: Liver fibrosis levels are stable for most coinfected patients undergoing TDF, despite control of HBV replication. Nevertheless, a concerning amount of liver fibrosis progression did occur, which could be partly explained by metabolic abnormalities and past severe immunosuppression and requires further evaluation.
Monotherapy with tenofovir disoproxil fumarate for multiple drug-resistant chronic hepatitis B: 3-year trial.[Pubmed:28370419]
Hepatology. 2017 Sep;66(3):772-783.
Combination therapy has been recommended for the treatment of patients harboring multiple drug-resistant hepatitis B virus (HBV). However, we recently demonstrated that monotherapy with Tenofovir Disoproxil Fumarate (TDF) for 48 weeks displayed noninferior efficacy to TDF plus entecavir (ETV) combination therapy in patients with HBV resistant to multiple drugs, including ETV and adefovir. Nonetheless, whether prolonged TDF monotherapy would be safe and increase the virologic response rate in these patients was unclear. Among 192 patients with HBV-resistance mutations to ETV and/or adefovir, who were randomized to receive TDF monotherapy (n = 95) or TDF/ETV combination therapy (n = 97) for 48 weeks, 189 agreed to continue TDF monotherapy (TDF-TDF group) or to switch to TDF monotherapy (TDF/ETV-TDF group) and 180 (93.8%) completed the 144-week study. Serum HBV DNA <15 IU/mL at week 48, the primary efficacy endpoint, was achieved in 66.3% in the TDF-TDF group and 68.0% in the TDF/ETV-TDF group (P = 0.80). At week 144, the proportion with HBV DNA <15 IU/mL increased to 74.5%, which was significantly higher compared with that at week 48 (P = 0.03), without a significant difference between groups (P = 0.46). By on-treatment analysis, a total of 79.4% had HBV DNA <15 IU/mL at week 144. Transient virologic breakthrough occurred in 6 patients, which was due to poor drug adherence. At week 144, 19 patients who had HBV DNA levels >60 IU/mL qualified for genotypic resistance analysis, and 6 retained some of their baseline resistance mutations of HBV. No patients developed additional resistance mutations throughout the study period. CONCLUSION: TDF monotherapy was efficacious and safe for up to 144 weeks, providing an increasing rate of virologic response in heavily pretreated patients with multidrug-resistant HBV.
