FDA Accepts 2 Merck sNDAs for HIV Drugs
FDA has accepted for review two Merck supplemental NDAs for Pifeltro (doravirine, 100 mg) and Delstrigo (doravirine 100 mg, lamivudine 300 mg and tenofovir disoproxil fumarate 300 mg). The applications seek approval for Pifeltro (in combination with other antiretroviral medicines) and Delstrigo for use in people living with HIV-1 who are switching from a stable antiretroviral regimen and whose virus is suppressed. The agency has set a user fee review action target date of 9/20 for both submissions.
The submissions were based on data from the Phase 3 DRIVE-SHIFT trial that met its primary endpoint — demonstrating non-inferior efficacy of switching to Delstrigo compared with continuing on a baseline regimen of two nucleoside reverse transcriptase inhibitors plus a boosted protease inhibitor, or boosted elvitegravir, according to the company.
