Breastfeeding, Antiretroviral, and Nutrition Study
- Conditions
- HIV Infections
- Interventions
- Drug: Maternal zidovudine/lamivudine/lopinavir-ritonavirDietary Supplement: Maternal protein and calorie supplement
- Registration Number
- NCT00164736
- Lead Sponsor
- Centers for Disease Control and Prevention
- Brief Summary
This is a comparative clinical trial among HIV-infected women and their infants to determine:
1. the benefit of nutritional supplementation given to women during breastfeeding
2. the benefit and safety of antiretroviral (ARV) medications given either to infants or to their mothers to prevent HIV transmission during breastfeeding
3. the feasibility of exclusive breastfeeding followed by early, rapid breastfeeding cessation
- Detailed Description
This study addresses the complex issues of HIV related maternal morbidity, mortality, and postnatal HIV transmission during breastfeeding and weaning in resource-poor countries. Objectives include assessment of mortality and morbidity among HIV-infected women; evaluation of interventions to reduce HIV transmission to infants exposed by breast milk; and assessment of early weaning as a risk-reduction strategy for infants of HIV-infected mothers.
The study will evaluate the following:
1. The efficacy of a high-density caloric/micronutrient nutritional supplement given to HIV-infected women who breastfeed in preventing maternal depletion (weight loss and micronutrient status).
2. The safety and efficacy of maternal or infant antiretroviral regimens, taken for up to 6 months during breastfeeding, in reducing infant HIV infection rates at 48 weeks.
3. The feasibility of exclusive breastfeeding for 6 months followed by rapid weaning.
Additional study objectives are to evaluate the feasibility of delivering these interventions in resource poor settings and to identify maternal, infant, and virologic factors associated with HIV transmission during breastfeeding.

Group Intervention Description Maternal ARVs & Nutrition Supplement Maternal zidovudine/lamivudine/lopinavir-ritonavir Extended maternal ARVs for prophylaxis (for the infant) \& daily nutritional supplement given to the mother Maternal ARVs & Nutrition Supplement Maternal protein and calorie supplement Extended maternal ARVs for prophylaxis (for the infant) \& daily nutritional supplement given to the mother Infant NVP & Nutrition Supplement Infant nevirapine Extended infant nevirapine for prophylaxis \& daily nutritional supplment given to the mother Infant NVP & Nutrition Supplement Maternal protein and calorie supplement Extended infant nevirapine for prophylaxis \& daily nutritional supplment given to the mother Maternal ARVs & No Nutrition Supplement Maternal zidovudine/lamivudine/lopinavir-ritonavir Extended maternal ARVs for prophylaxis (for the infant) \& no nutritional supplement given to the mother Infant NVP & No Nutrition Supplement Infant nevirapine Extended infant nevirapine for prophylaxis \& no nutritional supplment given to the mother No Drugs & Nutrition Supplement Maternal protein and calorie supplement No extended maternal ARV prophylaxis nor infant nevirapine prophylaxis \& daily nutritional supplement given to the mother. Note: As of March 2008, the third arm of the antiretroviral intervention, in which neither mother nor infant received drugs beyond enhanced standard of care, was stopped based on recommendations of a Data and Safety Monitoring Board review of interim efficacy results and safety data after 77% participants had received treatment assignment.
