Primary Outcome Measures

  • HIV viral load [ Time Frame: 48 weeks ]
Secondary Outcome Measures:
  • CD4 Count [ Time Frame: 48 weeks ]
Other Outcome Measures:
  • Drug Plasma Concentration [ Time Frame: Day 7,14,21,28 ]

Enrollment: 10
Study Start Date: April 2015
Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)

Arms Assigned Interventions
Experimental: Low-dose
Drug: Tenofovir(TDF)+Lamivudine(3TC)+Efavirenz(EFV)

The first 2 weeks, TDF (300 mg) + 3-TC (300 mg) + EFV (400 mg); week 3, TDF (200 mg) + 3-TC (300 mg) + EFV (400 mg ); week 4, TDF (150 mg) + 3-TC (300 mg) + EFV (400 mg).From week5, if the HIV viral load decreased as expected or no rebound, use TDF (200 mg) + 3-TC (300 mg) + EFV (400 mg) until study complete; if the viral load increases, switch to the standard treatment regimen: TDF (300 mg) + 3-TC (300 mg) + EFV (600 mg).

Detailed Description:

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.
