Study Endpoints

Primary Endpoints

Minimum age and weight for ATV is ≥ 3 months and ≥ 5 kg, respectively; participants receiving LPV/r will not receive cobicistat TOS.
Cohort 4 (Group 4)EXPERIMENTALParticipants age ≥ 4 weeks old weighing 3 to \< 6 kg will receive cobicistat TOS 30 mg (twice daily) and F/TAF TOS 15/1.88 mg, once daily with either ATV or LPV/r. Minimum age and weight for ATV is ≥ 3 months and ≥ 5 kg, respectively; participants receiving LPV/r will not receive cobicistat TOS.
Cohort 5 (Group 1)EXPERIMENTALParticipants ages ≥ 4 weeks old weighing ≥ 10 to \< 14 kg will receive F/TAF TOS 60/7.5 mg, once daily with the third unboosted drug.
Cohort 5 (Group 2)EXPERIMENTALParticipants ages ≥ 4 weeks old weighing ≥ 6 to \< 10 kg will receive F/TAF TOS 30/3.75 mg, once daily with the third unboosted drug.
Cohort 5 (Group 3)EXPERIMENTALParticipants ages ≥ 4 weeks old weighing ≥ 3 to \< 6 kg will receive F/TAF TOS 15/1.88 mg, once daily with the third unboosted drug.

Frequently asked questions about ATV

What is ATV used for in AIDS?

ATV is an investigational small molecule being studied for the treatment of Acquired Immune Deficiency Syndrome (AIDS) and HIV infections. It is currently in Phase 2 clinical development, and it is not yet approved by regulatory authorities.

Who makes ATV?

ATV is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol GILD. The company is conducting a Phase 2 clinical trial to evaluate the drug in pediatric patients with HIV.

What phase is ATV in?

ATV is in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved for commercial use. The drug is being studied in an active but not recruiting clinical trial for the treatment of AIDS and HIV infections.

What clinical trials is ATV in?

ATV is being studied in one Phase 2 clinical trial with the identifier NCT02016924. This trial is titled "Study of Cobicistat-Boosted Atazanavir (ATV/co), Cobicistat-Boosted Darunavir (DRV/co) and Emtricitabine/Tenofovir Alafenamide (F/TAF) in Children With HIV" and is enrolling 133 participants.

Is ATV the same as Atazanavir?

ATV is an abbreviation for Atazanavir, an antiretroviral medication. In the context of the clinical trial NCT02016924, ATV refers to Atazanavir boosted with cobicistat, which is being studied in combination with other antiretroviral agents for the treatment of HIV in children.
