Brief summary

The purpose of this study is to determine the mid levels of the tenofovir, lamivudine, and efavirenz, and 144 weeks safety and efficacy of the generic fixed dose combination of tenofovir /lamivudine/efavirenz tablets 300/300/600 mg in Thai HIV-infected patients.

Detailed description

The trial drug FDC of TDF/3TC/EFV is a new formulation combining fixed doses of the nucleoside reverse transcriptase inhibitors lamivudine 300 mg and tenofovir disoproxil fumarate 300 mg with the non nucleoside reverse transcriptase inhibitor efavirenz 600 mg for once daily and one-tablet HAART. Co-formulated TDF/3TC/EFV demonstrated bioequivalent to original individual EFV 3TC and TDF in Indian healthy volunteers (unpublished data). It has not been evaluated in clinical trials.

Interventions

DRUGgeneric FDC of TDF/3TC/EFV

Patients who were on individual TDF 3TC and EFV regimen before baseline will undergo TDM at baseline. Therapeutic drug monitoring (TDM) of generic FDC of TDF/3TC/EFV will be done after 4 weeks, to ensure steady state. At baseline and week 4 safety data will be obtained. In order to assess the efficacy and the long term safety of this drug, at week 12, 24 and 48 viral load, CD4 and safety parameters will be obtained.
