Novel Antiretroviral Agents

AbstractPurpose of ReviewCombination antiretroviral therapy (cART) has had dramatic effects on morbidity and mortality for persons living with HIV (PLWH). Despite significant progress in treatment efficacy, tolerability, and reducing pill burden, new agents are needed to address issues of resistance, drug-drug interactions, end organ disease, and adherence. This review covers novel ART agents recently approved or in development.Recent FindingsCapsid inhibitors (CAI) demonstrate high potency and potential for extended-duration dosing in pre-clinical trials. While previous maturation inhibitors (MI) were hampered by issues of drug resistance, a recent phase IIa trial for a second-generation MI demonstrated promising antiviral activity. A phase I trial to evaluate a transdermal implant of islatravir, a nucleoside reverse transcriptase translocation inhibitor (NRTTI), maintained concentrations above the target pharmacokinetic threshold at 12  weeks. The attachment inhibitor fostemsavir is available in the USA for compassionate use in multi-drug-resistant (MDR) HIV.SummaryNew antiretroviral agents show promise for both extended-duration dosing and MDR HIV.
