Title: A Phase II Open Label Clinical Trial of Maternal Zidovudine/Lamivudine and Either Nevirapine or Nelfinavir for Maximal Reduction of Mother-to-child HIV Transmission in Resource-limited Settings Among Breastfeeding Populations
Brief Summary: The purpose of the study is to demonstrate that a regimen using highly active antiretroviral therapy (HAART) to maximally suppress maternal viral load in the late antenatal period and during the first six months of lactation is safe, effective and can be implemented in resource poor settings in order to reduce the risk of HIV transmission to the infant.
