Merck Discloses New Islatravir Data Supporting Safety Profile For PrEP Regime For HIV Infection - Merck & Co (NYSE:MRK)

Merck & Co Inc MRK has announced new data from Phase 2a trial evaluating islatravir for pre-exposure prophylaxis (PrEP) of HIV-1 infection in adults at low risk of contracting HIV-1.

These data were shared at the International AIDS Society Conference on HIV Science.
Islatravir (MK-8591) is an investigational nucleoside reverse transcriptase translocation inhibitor.
