This Funding Opportunity Announcement (FOA) invites applications for Planning Grants (R34) that will strengthen the HIV oral pre-exposure prophylaxis (PrEP) care continuum by developing and pilot testing interventions to improve PrEP care engagement and retention among individuals at substantial risk for HIV infection, as well as interventions to support PrEP medication adherence and persistence as indicated.

The National Institute on Drug Abuse (NIDA) supports a program of longitudinal cohorts to address emerging and high priority research on HIV/AIDS in the context of injection and non-injection substance abuse. These cohorts provide a strong resource platform for current and future collaborative efforts with other investigators to address emerging questions related to HIV pathogenesis, prevention, and treatment in the context of substance abuse, as well as to foster the creativity and efficiency of investigator–initiated research projects.

This Funding Opportunity Announcement (FOA) encourages Exploratory and developmental bi-phasic research applications to support the identification and optimization of small molecules or RNAs that interact with host epigenetic machinery to mediate long-term or permanent epigenetic silencing of HIV-1 proviruses.

The purpose of this FOA is to encourage applications for research training programs to strengthen the scientific capacity of institutions in low- and middle-income countries (LMICs) to conduct HIV research relevant to the evolving HIV epidemic in their country.

The overall goal of the Fogarty International Center (FIC) HIV Research Training Program is to strengthen the scientific capacity of institutions in low- and middle-income countries (LMICs) to conduct HIV research on the evolving HIV epidemic in their countries. This FOA encourages collaborative applications from U.S.

The Fogarty HIV Research Training Program supports research training that strengthens HIV research capacity of institutions in low-and middle-income countries (LMIC). This FOA offers an opportunity for LMIC institutions to submit a planning grant application to participate in the Fogarty HIV Research Training Program. These applications must propose a plan to develop a research training program and the subsequent application that will be submitted in response to the companion D43 FOA (PAR-16-279).
