Research Summary

Since the early 1990's Dr. Fowler has worked on a number of the key phase I-III perinatal and pediatric HIV treatment clinical trials conducted both in the U.S and in international settings. These include some of the early treatment trials of pediatric antiretrovirals as well as international trials for prevention of mother to child transmission of HIV (PMTCT) including the HIVNET 06 and 012 trials the PEPI infant prophylaxis trial, the Kisumu Infant Breastfeeding trial, Kesha Bora Trial in Nairobi, the HIVIGLOB/ SWEN trial, the HPTN 027 ALVAC perinatal vaccine trial, and the HPTN 046 trial of extended infant nevirapine infant prophylaxis.

Most recently Dr. Fowler has served as Chair of the NIH supported PROMISE trial (1077BF/1077FF), a large multisite PMTCT trial within the IMPAACT network assessing what the optimal strategies are for both PMTCT, safety and improving maternal and infant health. In addition, Dr. Fowler oversee studies of HIV primary prevention using microbicides and oral antiretroviral agents in Kampala Uganda at as part of the MTN network. These primary prevention trials include both young and older women, ages 18-49 who are at high risk for HIV acquisition.
