Elsulfavirine

Elsulfavirine (trade name Elpida; also known as VM 1500) is drug used to treat HIV infection. It is a non-nucleoside reverse transcriptase inhibitor (NNRTI).^[1][2][3] Elsulfavirine is a prodrug which is metabolized to the active antiviral agent deselsulfavirine (also known as VM 1500A).^[4] It was developed by the Russian company Viriom.^[5]

In June 2017, elsulfavirine was approved for use in Russia as an oral formulation for the treatment of HIV-1 infections in combination with other antiretroviral drugs.^[4][6] Currently, elsulfavirine is used in antiretroviral therapy regimens in the Russian Federation, which includes the combination elsulfavirine + lamivudine (or emtricitabine) + tenofovir.^[7]

Long-acting injectable formulations of eslulfavarinin and deselsulfavarine are under investigation.^[8][9]

In addition, Roche is investigating the use of elsulfavirin for the treatment of COVID-19 and it is currently in Phase II clinical trials for this possible indication.^[5]
