Long-acting drug delivery systems are promising platforms to improve patient adherence to medication by delivering drugs over sustained periods and removing the need for patients to comply with oral regimens. This research paper provides a proof-of-concept for the development of a new optimized in situ forming injectable depot based on a tetrabenzylamine-tetraglycine-d-lysine-O-phospho-d-tyrosine peptoid-D-peptide formulation ((NPhe)4GGGGk(AZT)y(p)-OH).

      Healthcare trends continue to move from hospital to home and many targeted therapies and precision medicines are now being designed to be self-administered by patients or delivered in a home setting. In the case of long acting injectables and bio-therapeutics, the importance of optimal drug/biologic-device combination in terms of user needs becomes critical for successful clinical outcomes.

          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 long-acting formulation of rifabutin is effective for prevention and treatment of Mycobacterium tuberculosis. Nat Commun. 2022 Aug 8;13(1):4455. doi: 10.1038/s41467-022-32043-3. PMID: 35941109.

                Tuberculosis (TB) is a communicable disease caused by Mycobacterium tuberculosis (Mtb) and is a major cause of morbidity and mortality. Successful treatment requires strict adherence to drug regimens for prolonged periods of time. Long-acting (LA) delivery systems have the potential to improve adherence.

                    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.
