Adherence to antiretroviral therapy (ART) is imperative for viral suppression and reducing HIV transmission, but many people living with HIV report difficultly sustaining long-term adherence. Long-acting injectable (LAI) ART has the potential to transform HIV treatment and prevention. However, little LAI ART-related behavioral research has occurred among women, particularly outside of clinical trials.

Transgender Women's Concerns and Preferences on Potential Future Long-Acting Biomedical HIV Prevention Strategies: The Case of Injections and Implanted Medication Delivery Devices (IMDDs). AIDS Behav. 2020 May;24(5):1452-1462. doi: 10.1007/s10461-019-02703-5. PMID: 31654172; PMCID: PMC7181384.

There are several long-acting biomedical HIV prevention products in the development pipeline, including injections and implanted medication delivery devices (IMDDs). It is critical to understand concerns and preferences on the use of these products in populations that shoulder a disproportionate burden of the HIV epidemic, such as transgender women. This will allow researchers and public health professionals to construct interventions tailored to the needs of these women to promote optimal use of these tools. In studies of other biomedical HIV prevention products (e.g., oral PrEP) it is clear that transgender women have unique concerns related to the use of these strategies.

High HIV incidence and low adherence to daily oral PrEP among women underscore the need for more acceptable and easier to use HIV prevention products. Global demand for injectable contraception suggests that new, long-acting, injectable formulations could meet this need. We examine acceptability of a long-acting injectable PrEP among HIV-uninfected women in Zimbabwe, South Africa and two United States phase 2 trial sites.

Sustained Release of Antivirals for Treatment or Prevention of HIV (SRATP) (R01 Clinical Trial Not Allowed)

Grant Source: 

The purpose of this Funding Opportunity Announcement (FOA) is to stimulate the high-risk research needed to develop new and innovative sustained release antiviral strategies for treatment of HIV disease or the prevention of HIV transmission and acquisition. Adherence to dosing regimens is a shared critical issue for both HIV treatment and prevention.

Advancing Sustained/Extended Release for HIV Prevention (A-SER)

Grant Source: 

The purpose of this Funding Opportunity Announcement (FOA) is to stimulate the development of new and innovative sustained/extended release (SER) drug delivery systems (DDS) that can achieve extended durations (months to years) and provide systemic protection from all routes of HIV infection/transmission in at-risk individuals.

Structural and pharmacological evaluation of a novel non-nucleoside reverse transcriptase inhibitor as a promising long acting nanoformulation for treating HIV

Structural and pharmacological evaluation of a novel non-nucleoside reverse transcriptase inhibitor as a promising long acting nanoformulation for treating HIV. Antiviral Res. 2019;167:110-116. doi:10.1016/j.antiviral.2019.04.010. PMID: 31034849; PMCID: PMC6554724.

Combination antiretroviral therapy (cART) has been proven effective in inhibiting human immunodeficiency virus type 1 (HIV-1) infection and has significantly improved the health outcomes in acquired immune deficiency syndrome (AIDS) patients. The therapeutic benefits of cART have been challenged because of the toxicity and emergence of drug-resistant HIV-1 strains along with lifelong patient compliance resulting in non-adherence.

Semi-solid prodrug nanoparticles for long-acting delivery of water-soluble antiretroviral drugs within combination HIV therapies

The increasing global prevalence of human immunodeficiency virus (HIV) is estimated at 36.7 million people currently infected. Lifelong antiretroviral (ARV) drug combination dosing allows management as a chronic condition by suppressing circulating viral load to allow for a near-normal life; however, the daily burden of oral administration may lead to non-adherence and drug resistance development.
