Evaluating Islatravir Administered Via Microneedle Array Patch for Long-Acting HIV Pre-exposure Prophylaxis Using Physiologically Based Pharmacokinetic Modelling.

Technologies for long-acting administration of antiretrovirals (ARVs) for the prevention and treatment of HIV are at the forefront of research initiatives aiming to tackle issues surrounding drug adherence with the current standard of once-daily oral administration. Islatravir (ISL) is an emerging ARV that shows promising characteristics for long-acting prevention and treatment both orally as well as through alternative routes of administration.

    Cabotegravir extended-release (ER) injectable suspension (Apretude™) is the first long-acting injectable option to be approved for HIV-1 pre-exposure prophylaxis (PrEP). As an HIV-1 integrase strand transfer inhibitor, cabotegravir ER injectable suspension prevents DNA integration and inhibits HIV-1 replication.

      People who inject drugs (PWID) have extraordinarily low uptake of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) despite high levels of need. Long-acting PrEP modalities hold promise for HIV prevention among PWID, but product preferences remain poorly understood.

            A novel long-acting regimen (LAR) of cabotegravir and rilpivirine for HIV treatment requires dosing every 2 months instead of daily. We assessed what proportion of people living with HIV and physicians would be interested in trying and offering LAR respectively and why.

              Notice of Special Interest (NOSI): Sustained Release of Antivirals for Treatment or Prevention of HIV or Treatment of Latent TB/HBV (SRATP)

              Clinical experience for HIV treatment and prevention has demonstrated that adherence to a drug regimen schedule is a significant factor in the success of the HIV treatment regime and/or prevention strategies. Effective treatment of HIV-infected individuals requires strict adherence to a multi-component regimen of antiretroviral agents taken at least daily for the remainder of a patient’s life. Non-adherence can lead to emergence of drug-resistance and loss of therapeutic effectiveness. Among people living with HIV, morbidity and mortality is increasingly driven by co-infections, such as tuberculosis (TB) and hepatitis B, where the compliance and completion of prolonged multidrug regimens are significant factors in treatment success.

              Effective prevention requires that the inhibitor be present at the right time, place, and concentration to stop HIV transmission and acquisition. Although many factors (social, behavioral, and individual preference) can influence adherence, the use of drug delivery systems to provide for a longer therapeutic exposure or window of protection and/or less frequent administration may improve their consistent use, reduce dosing intervals, and potentially improve adherence to the drug regimens.

              Development of safe, effective, and well-tolerated sustained release (SR)/long acting (LA) products and strategies that maintain consistent and effective drug levels in plasma and target tissues for longer periods of time is critical for successful treatment and prevention of HIV and HIV-associated co-infections.

                Increasing Uptake of Long-Acting Injectable Antiretrovirals Among People with HIV

                This notice announces the opportunity to apply for funding under the Increasing Uptake of Long-Acting Injectable Antiretrovirals Among People with HIV cooperative agreement Increasing viral suppression and client retention in care are critical components of meeting the goals of the National HIV/AIDS Strategy (2022-2025) and ending the HIV epidemic. In order to reach these goals, it is imperative for HIV care communities to address health care inequities. With the advent of FDA-approved long-acting injectable (LAI) antiretroviral (ARV) medication formulations, initiatives that promote, facilitate, and evaluate the uptake and ongoing utilization of LAI ARV medication may improve clinical outcomes for people with HIV, especially for minority populations who continue to face disparate health care inequities and stigma. This project is designed to develop protocols, implement them and modify as needed, to increase uptake of LAI ARV medications among people of color with HIV, since LAI ARV medications may offer benefits in addressing health inequities and achieving viral suppression.

                    The ability to successfully develop a safe and effective vaccine for the prevention of HIV infection has proven challenging. Consequently, alternative approaches to HIV infection prevention have been pursued, and there have been a number of successes with differing levels of efficacy. At present, only two oral preexposure prophylaxis (PrEP) products are available,
