Brief summary
The MONOD trial aim to evaluate the implementation of early antiretroviral treatment strategies in HIV-infected infants and assess the feasibility and efficacy of simplifying the initial proposed regimen after a successful one year treatment. The initial treatment is AZT-3TC-LPV/r twice a day. After one year, the children will be randomized in one of the following : arm 1-reference AZT-3TC-LPV/r twice daily; arm 2-simplified ABC-3TC-EFV once daily. The perspective of this project is to identify antiretroviral strategies to improve treatment access and adherence for children in sub-saharian Africa.
Interventions
AZT sirup (10mg/ml): 4 mg/kg or 180 mg/m2 twice daily 3TC sirup (10mg/ml): 4 mg/kg twice daily LPV/r sirup (80/20 mg/ml): 12 mg/kg twice daily
ABC sirup (20mg/ml): 16 mg/kg once daily in the morning 3TC sirup (10mg/ml): 8 mg/kg once daily in the morning EFV sirup (30mg/ml): 25 mg/kg once daily in the morning before food intake

Eligibility
Inclusion criteria
for antiretroviral treatment initiation: * infant follow-up in one of the trial site * HIV-1 infection diagnose by RT PCR after 6 weeks of life * age between 3 and 12 month at the antiretroviral treatment initiation * naive of antiretrovirals except if received for the prevention of mother to child HIV transmission * HB\>=7 g/dl, neutrophiles\>750/mm3, creatinin\<3xULN, TGO and TGP\<3xULN * signed informed consent
Exclusion criteria
for antiretroviral treatment initiation: * HIV-2 infection or HIV-1/HIV-2 co-infection * Known intolerance to one of the trial treatment * HB\<7 g/dl, neutrophiles\<750/mm3, creatinin\>3xULN, TGO or TGP\>3xULN Inclusion Criteria for randomisation at 12 months in the simplification phase: * age 24 months at most * virological success define as 2 consecutive indetectable HIV RNA measured by RT PCR at least 3 months apart.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Initial therapeutic cohort: Virological success | 12 months | survival without virological failure (death or loss of follow-up or virologic failure, i.e. HIV-ARN ≥400 copies/mL on one consecutive sample), analysis of resistance profile. |
| Randomised simplification phase: Virological success | 25 months | survival without virological failure (death or loss of follow-up or virologic failure (HIV-ARN ≥400 copies/mL ))from M13 to M25. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Virological success | 12 months | HIV RNA \< 400 copies / mL |
| Immunological response | 12 and 25 months | CD4+ lymphocyte absolute count and percentage |
| Adherence | 12 and 25 months | measurement at each protocol visit of the three last days treatment intake to be corelated to the antiretroviral concentration and virological success |
| Tolerance | 12 and 25 month | occurence of grade 3 and 4 adverse events related to the trial treatment, particularly occurence of immune reconstitution inflammatory syndrome |
| Antiretroviral and cotrimoxazol pharmacokinetic parameters | 6, 19 and 25 months | The following parameters will be measured or calculated: maximal and minimal concentration (Cmax, Cmin), half life (t1/2), Aire Under the Curve (AUC), clearance and volume of distribution, for all antiretroviral (according to treatment arm : AZT, 3TC, LPV, ABC, EFV) and cotimoxazol. |
| Resistance to antiretroviral | 12 and 25 months | Genotyping to analyse resistance mutation when virological failure |
