Latency and Early Neonatal Provision of Antiretroviral Drugs Clinical Trial — LEOPARD  

HIV Clinical Trial

Official title: Latency and Early Neonatal Provision of Antiretroviral Drugs Clinical Trial

Status Completed

Clinical Trial Summary

The investigators propose a non-randomized clinical trial of 60 HIV-infected infants identified within 48 hours of birth and their mothers to investigate the consequences of very early ART on the establishment and maintenance of the viral reservoir.

The first phase (early ART initiation within 48 hours of birth) will examine the trajectory i.e. changes over time of the viral reservoir and detection of HIV-specific antibody responses in infants testing HIV-positive within 48 hours of birth and initiating early ART.

Secondary pathogenesis aims will test whether markers of neonatal immune quiescence are associated with the extent of seeding and rate of decline of the viral reservoir when ART is started at a young age and investigate whether markers in infant stool samples can be used as a non-invasive method of defining relevant immune and HIV-specific parameters associated with viral reservoir size.

The investigators hypothesize that developmental characteristics of newborn immunity may make this period the optimal time to begin ART and influence the seeding of the viral reservoir.

Clinical Trial Description

Prevention of mother-to-child transmission (PMTCT) programs using antiretrovirals (ARVs) have had tremendous success in sub-Saharan Africa. However, HIV transmission continues to occur because (1) implementation of PMTCT is incomplete and (2) ARV interventions are not 100% effective in blocking infection. Thus the challenge of providing treatment to HIV-infected children is far from over. The capacity of early ART treatment to favorably influence the viral reservoir and potentially lead to post-treatment cessation viral control needs to be described in the population of infants, and to identify useful public health strategies. ;
