Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has approved Pifeltro (doravirine, 100 mg), a new non-nucleoside reverse transcriptase inhibitor (NNRTI) to be administered in combination with other antiretroviral medicines. Pifeltro is indicated for the treatment of HIV-1 infection in adult patients with no prior antiretroviral treatment experience, and is administered orally once daily with or without food. Pifeltro does not cure HIV-1 infection or AIDS.


The FDA also approved Delstrigo, a once-daily fixed-dose combination tablet of doravirine (100 mg), lamivudine (3TC, 300 mg) and tenofovir disoproxil fumarate (TDF, 300 mg).

Pifeltro is contraindicated when co-administered with drugs that are strong cytochrome P450 (CYP)3A enzyme inducers as significant decreases in doravirine plasma concentrations may occur, which may decrease the effectiveness of Pifeltro.
