Frequently asked questions about Delstrigo

What is Delstrigo used for?

Delstrigo is a small molecule treatment for HIV-1 infection in adults. It is being studied as a first-line antiretroviral therapy for people starting treatment, and it is given as a complete regimen rather than combined with other HIV medicines.

Who makes Delstrigo?

Delstrigo is developed by Merck & Company, Inc., which trades on the New York Stock Exchange under the ticker MRK. Merck is the sponsor of the clinical program evaluating the drug in HIV-1 infection.

What phase is Delstrigo in?

Delstrigo is in Phase 3 clinical development for HIV-1 infection. It is an investigational regimen and is not described as approved. The Phase 3 program is evaluating it in adults beginning first-line antiretroviral therapy.

What clinical trials is Delstrigo in?

Delstrigo is being studied in the Phase 3 trial NCT05924438, a randomized, controlled, non-inferiority study comparing DOR/3TC/TDF with DTG/TAF/FTC in participants infected with HIV-1 who are starting first-line antiretroviral therapy. The trial is active and not recruiting, with 600 participants enrolled in South Africa.

How is the Delstrigo trial designed?

NCT05924438 is a randomized, controlled, Phase 3 non-inferiority study with 600 participants. It enrolls adults aged 18 years and older of all sexes in South Africa and compares DOR/3TC/TDF against DTG/TAF/FTC in people with HIV-1 beginning first-line antiretroviral therapy.
