Abstract
Abstract
Purpose
The pharmacology, pharmacokinetics, and role in therapy of fostemsavir in management of HIV-1 infection are reviewed, with an emphasis on clinical efficacy and safety data from phase 2 and phase 3 clinical trials.
Summary
Fostemsavir (Rukobia, ViiV Healthcare), is a prodrug of temsavir, a novel pyridine compound with potent activity against HIV-1. Fostemsavir, the first oral attachment inhibitor, was approved and granted the breakthrough therapy designation by the Food and Drug Administration for use in combination with other antiretroviral agents for the treatment of HIV-1 infection in heavily treatment-experienced adults. As absorption of temsavir is not altered with increased gastric pH, patients may take acid suppressive agents such as famotidine during fostemsavir therapy.Temsavir is primarily metabolized through hydrolysis but also via cytochrome P-450 (CYP) oxidation; therefore, coadministration of fostemsavir with strong CYP3A inducers such as rifampin, carbamazepine, phenytoin, mitotane, enzalutamide, or St John’s wort is contraindicated because it may result in significantly lower temsavir exposure, which can ultimately impair virologic response. The most common adverse reactions associated with fostemsavir use include nausea, diarrhea, headache, abdominal pain, dyspepsia, fatigue, rash, and sleep disturbance.
Conclusion
Fostemsavir may be an effective option for heavily treatment-experienced adults with multidrug-resistant HIV-1 infection. Fostemsavir is a particularly attractive treatment option for patients who are no longer able to achieve viral suppression with use of currently available antiretroviral therapies and who are able to adhere to a twice-daily oral regimen.
