A clinical trial to assess the safety and tolerability of THV01, a therapeutic treatment against HIV composed of two vaccines, in HIV-infected patients treated by antiretroviral treatment. Three doses will be assessed and a control group of patients who will receive a placebo (non-active product) is included. The immune response generated by the THV01 treatment will also be assessed.

Inclusion Criteria

1.Patient infected with clade B HIV-1;
2.Confirmation of a Gag clade B genotyping performed at screening;
3.Patient must be treated by a triple agents therapy for more than 12 months at baseline: two nucleosidic reverse transcriptase inhibitors plus one boosted protease inhibitor, or two nucleosidic reverse transcriptase inhibitors plus one non nucleosidic reverse transcriptase inhibitor;
4.Patient must be treated for more than 60 days at baseline by two (2) nucleosidic reverse transcriptase inhibitors plus a ritonavir boosted protease inhibitor treatment among darunavir+ritonavir or lopinavir+ritonavir;
5.Patient’s HIV plasma viral load must have remained = 150,000 copies mL-1 at any monitoring time (apart measurement during primo-infection if recorded);
6.Patient with HIV plasma viral load persistently = 50 copies mL-1 during the 12 months prior to screening;
7.Patient’s CD4+ T cells count = 300 cells per mm3 at any time since diagnosis;
8.Patient’s CD4+ T cells count < 500 cells per mm3 at least once from diagnosis to initiation of antiretroviral treatment
9.Patients with CD4+ T cells count = 600 cells per mm3 at baseline;
10.Man or woman aged 18-55 years;
11.Patient with haematological and biochemical laboratory parameters as follows and within 7 days of baseline:
?Haemoglobin > 9.0 g dL-1;
?Absolute neutrophil count = 750 mm-3;
?Platelets = 100,000 mm-3;
?Total serum creatinine = 1.3 x ULN (upper limit of normal);
?Creatinine clearance > 50 mL min-1 by the Cockcroft-Gault equation within 60 days of entry ;
?Prothrombin time (PT) < 1.2 x ULN;
?Total serum bilirubin < 2.0 x ULN (a higher total bilirubin value may be permitted if the subject was taking atanazir or indinavir and the elevation in total bilirubin is due to increased unconjugated bilirubin);
?Alkaline phosphatase, AST (SGOT) and ALT (SGPT) < 1.5 x ULN;
?Serum lipase less than or equal to 2.0 x ULN;
12.Patient should be able and willing to comply with study visits and procedures as per protocol;
13.Patient should understand, sign and date the written voluntary informed consent form at the screening visit prior to any protocol-specific procedures being performed;
14.Patient should be affiliated to a social security regimen (for French sites);
15.Patients must agree to use in addition to the condom, a second method (one for the patient and one for the partner) of medically acceptable form of contraception during the study and for 3 months after end of study or early termination;
16.Women of childbearing potential will enter the study after confirmed menstrual period and a negative pregnancy test In case of pregnancy suspicion, a pregnancy test must be performed immediately.
