Merck Reports Topline Data From Phase 3 Trials Of Doravirine + Islatravir To Treat HIV-1 Infection

(RTTNews) - Merck & Co Inc. (MRK), Thursday reported topline results from two pivotal Phase 3 trials evaluating the company's drug candidate islatravir in combination with its approved HIV drug doravirine for the treatment of adults with virologically suppressed HIV-1 infection.

The trials met primary efficacy criteria for non-inferiority of doravirine/ islatravir (DOR/ISL) combination compared to antiretroviral therapies in adults with virologically suppressed HIV-1. However, the superiority criteria were not met in one of the trials. Safety profiles of DOR/ISL were generally comparable with other therapies in these trials.

The company plans to file these data with regulatory authorities.

A Phase 3 study of DOR/ISL combination in people with HIV who had not previously received treatment is underway.

Islatravir is currently being evaluated in multiple early and late-stage studies in combination with other antiretroviral therapies for the treatment of HIV-1.
