ART Drug Dosage Adjustment in HIV-infected Population

ART Drug Dosage Adjustment Using FSCII in Chinese HIV-infected Population

The purpose of this study is to determine efficacy of the combination of low dose of Tenofovir, Efavirenz and Lamivudine in treating HIV-infection.

The feedback system control (FSC) technique has been developed to rapidly identify optimal combinations for therapeutic purposes. Low dose of TDF+3TC+EFV combination has been test in vitro study by FSC which showed high efficacy and now the investigators apply it to human to further optimize the ART combination.
