Brief summary
The study will begin with a two-week lead-in period (W-2 and W-1), when participants randomized to Codivir® will receive Codivir® 2 mL, 1 subcutaneous injection every day. Participants randomized to Standard Antiretroviral Treatment will wait for the next step. At V0 (W0, D0) all participants will start the antiretroviral treatment described above. From V0 (W0, D0) to V6 (W12, D84) participants randomized to Codivir® will receive Codivir® as complementary therapy to the above antiretrovirals on alternate days (every other day). At V6 (W12, D84) treatment with Codivir® will end. At V7 (W24, D168) participation in the study will end. Viral load will be monitored during the study. In case of failure, participation in the study will be discontinued and the participant will be referred to receive the best treatment available for their case.
Interventions
Application of Informed Consent Form.
Assessment of inclusion, exclusion and discontinuation criteria.
Collection of demographic data.
Weight and height measurement and body mass index calculation.
HR, BP and FR and T°, in addition to oximetry.
Medical history and physical examination at screening. In other consultations, the medical evaluation is focused on viral load, CD4+ and new complaints.
Blood collection for safety laboratory exams. Blood count, Na, K, U, C, amylase, total cholesterol and fractions, triglycerides, coagulation tests (TTTP, TT, platelets), TGO, TGP, AP, GGT, glycated hemoglobin, total bilirubin and fractions, creatine kinase and CKmB and urine I.
β-HCG in urine in non-sterile women
HBV (HBsAg, Anti-HBc) and HCV (anti-HCV-Ab).
Assignment to the Standard Antiretroviral Treatment + Codivir® group or the Standard Antiretroviral Treatment only group
Caspases and Annexin V.
PBMCs will be isolated by density gradient centrifugation. The cells will then be tested for CD4+, CD8+, CD38 and HLA DR
ultrasensitive CRP, D-dimer.
Total HIV DNA will be measured to estimate the size of the viral reservoir throughout the preparation.
Anti-HIV-1 specific antibody titers in plasma.
Performed on plasma.
The participant is trained to self-inject Codivir®
the participant receives Codivir®
The Codivir® used since the last visit is accounted for
Record of concomitant medications used.
Collection and recording of adverse events.
Tenofovir - inhibits HIV-1 reverse transcriptase activity by competing with the natural substrate, deoxyadenosine 5'-triphosphate and, upon incorporation into DNA, causes DNA chain termination. * Lamivudine - potent selective inhibitor of HIV-1 and HIV-2 replication in vitro. * Darunavir - prevents the formation of mature infective viral particles, indicated for the treatment of the human immunodeficiency virus (HIV), which causes AIDS. * Ritonavir: antiretroviral protease inhibitor, widely used in combination with other protease inhibitors in the therapy and prevention of HIV infection, which causes the syndrome acquired immunodeficiency (AIDS). * Single solid formulation (in 1 tablet) 1x/day with: * Tenofovir (TDF) 300 mg * Lamivudine (3TC) 300 mg * Darunavir (DRV) 800 mg, 1x/day * Ritonavir (RTV) 100 mg, 1x/day

Study design
Intervention model description
Randomization Forty participants with a recent diagnosis of HIV infection, without previous antiretroviral treatment and indication to start antiretroviral treatment, will be randomized as follows: * 20 participants will receive Standard Antiretroviral Treatment + Codivir * 20 participants will only receive Standard Antiretroviral Treatment A randomization will be balanced by sex and age.
