Inclusion Criteria
  • 18 to 65 years.
  • Documented asymptomatic HIV-1 infection of 3-12 months duration (all patients must have a positive Western blot, including the p31 band whose appearance indicates infection of more than 90 days duration).
  • Not having received ART
  • CD4 T-lymphocyte count> 350 / μl
  • Patient giving written informed consent
Exclusion Criteria
  • Active HBV (HBsAg+ or DNA+) and/or HCV (RNA+) infection in screening.
  • ALT> 2 UNL, glomerular filtration rate <70 mL / 1.73 m2, leukocytes <4000 / mm3, total lymphocyte count <1000 / mm3, platelets <100,000 / mm3 or Hg <12g / dL.
  • Pregnancy or active breastfeeding
  • Ongoing or previous pleural effusion
  • Chronic obstructive pulmonary disease, bronchial asthma or recent chest trauma.
  • History of gastrointestinal or other bleeding.
  • Any concomitant treatment with potentially dangerous drug interaction with dasatinib.
  • Any clinical condition, at the opinion of the investigator, contraindicating participation (for example,
  • Active neoplastic disease, active concomitant infection, etc.)

PlaceboPlaceboPlacebo monotherapy will be given for 4 weeks. Antiretroviral therapy (ART) based on unboosted integrase inhibitors will be initiated at week 4 (S4) and placebo will be continued with ART until week 12.
DasatinibDasatinibDasatinib monotherapy (70 mg/day) will be given for 4 weeks. Antiretroviral therapy (ART) based on unboosted integrase inhibitors will be initiated at week 4 (S4) and dasatinib will be continued with ART until week 12.
Primary Outcome Measures
NameTimeMethod
Safety and tolerance of dasatinib with and without antiretroviral therapy, measured by number of AEs and SAEs52 weeks

Measured by number of AEs and SAEs

Secondary Outcome Measures
NameTimeMethod
Antiretroviral capacity of dasatinibat week 0 and 4

Measured by quantification of plasma HIV-1 viral load during 4-week administration of dasatinib monotherapy.

Changes in the viral reservoirs of patients with recent HIV-1 infection induced by dasatinib administration.at week 0, 4, 16 and 52

Measured by changes in the viral reservoirs (integrated DNA, genetically intact virus, residual and induced viral replication and determination of integration sites)

Changes in markers of inflammation and immune activation induced by dasatinib administration.at week 0, 4, 16 and 52

Measured by changes in ultra-sensitive CRP, IL6, TNF alpha and CD4/CD8, CD25, CD69, CD38, HLA-DR+.

Changes in SAMHD1 phosphorylation levels and cytotoxic activity against HIV-1 induced by dasatinib.at week 0, 4, 16 and 52

Measured by NK phenotyping and in vitro replication inhibition tests.

Pharmacokinetic interactions of coadministration non-boosted integrase inhibitor-based antiretroviral therapy with dasatinib.at week 1, 2, 3, 4, 8, 12, 16

Measured by Cmin

Impact of dasatinib on markers of senescenceat week 0, 4, 16 and 52

Measured by expression in PBLs of beta-galactosidase, Bcl-2, Histone H2A, p16 and CD87.
