Stopping the control arm in response to the DSMB: Mother's choice of HIV prophylaxis during breastfeeding in the BAN Study

Abstract: The Data and Safety Monitoring Board (DSMB) for the Breastfeeding, Antiretrovirals, and Nutrition study, a clinical trial aimed to prevent postnatal HIV transmission, recommended halting randomization to the enhanced standard-of-care (control) arm. The 67 mother–infant pairs on the control arm and less than 21weeks postpartum at the time of the DSMB recommendation were read a script informing them of the DSMB decision and offering them the maternal or infant antiretroviral interventions for the remainder of the 28-week breastfeeding period. This paper describes the BAN study response to the DSMB decision and what the women on the control arm chose, when given a choice to start the maternal or infant antiretroviral interventions.
