Merck to launch two new HIV-1 medicines

October 10, 2018 0 By CH Unnikrishnan

Delstrigo and Pifeltro are cleared for sale in US to treat HIV-1 infection, Merck said.

Delstrigo is a once-daily fixed-dose combination tablet of doravirine (100 mg), lamivudine (3TC, 300 mg) and tenofovir disoproxil fumarate (TDF, 300 mg). Pifeltro (doravirine, 100 mg) is a new non-nucleoside reverse transcriptase inhibitor (NNRTI) to be administered in combination with other antiretroviral medicines.

Both Delstrigo and Pifeltro are indicated for the treatment of HIV-1 infection in adult patients with no prior antiretroviral treatment experience, and are administered orally once daily with or without food. Delstrigo contains a boxed warning regarding post-treatment acute exacerbation of hepatitis B infection.

The approvals are based on findings from the pivotal, randomized, multicenter, double-blind, active controlled Phase 3 trials, DRIVE-AHEAD and DRIVE-FORWARD, evaluating the efficacy and safety of Delstrigo and Pifeltro, respectively, in participants infected with HIV-1 with no antiretroviral treatment history.
