Investigational Antiretroviral Drugs: What is Coming Down the Pipeline.

ABSTRACT: Over the past 30 years, antiretroviral drug regimens for treating HIV infection have become more effective, safer, and more convenient. Despite 31 currently approved drugs, the pipeline of investigational HIV drugs remains full. Investigational antiretroviral drugs include the nucleoside analogue reverse transcriptase translocation inhibitor (NRTTI) MK-8591, a long-acting compound that could be dosed once weekly. Investigational nonnucleoside analogue reverse transcriptase inhibitors (NNRTIs) include doravirine, which is active in vitro against NNRTI-resistant HIV and was potent and well-tolerated when used in combination with a dual-nucleoside analogue RTI (nRTI) backbone in treatment-naive individuals.New integrase strand transfer inhibitors (InSTIs) include recently approved bictegravir, which is active against InSTI-resistant viral strains in vitro and was potent and well-tolerated in combination regimens in treatment-naive individuals, and investigational cabotegravir, which is being studied with monthly parenteral dosing for HIV maintenance treatment and with bimonthly dosing for HIV preexposure prophylaxis (PrEP). Investigational HIV entry inhibitors include the new CD4 attachment inhibitor fostemsavir, which targets HIV envelope glycoprotein 120, and recently approved ibalizumab, which binds the CD4 receptor.
