Frequently asked questions about PI

What is PI used for?

PI is an investigational small molecule being studied for the treatment of Acquired Immunodeficiency Syndrome (AIDS) and HIV infections. It is being developed by Gilead Sciences, Inc. (GILD) and is currently in Phase 3 clinical development.

What does PI target?

PI is a protease inhibitor, a class of antiretroviral drugs that work by blocking the protease enzyme, which HIV needs to replicate. By inhibiting this enzyme, PI helps reduce the viral load in patients with HIV infection.

Who makes PI?

PI is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol GILD. Gilead is conducting clinical trials to evaluate the safety and efficacy of PI in patients with HIV.

What phase is PI in?

PI is currently in Phase 3 clinical development. It is an investigational drug and has not yet been approved by regulatory authorities. A Phase 3 trial has been completed to evaluate its efficacy and safety in virologically suppressed HIV-1 infected patients.

What clinical trials is PI in?

PI has been studied in a completed Phase 3 clinical trial with the identifier NCT01475838. This trial enrolled 438 participants and evaluated switching from a ritonavir-boosted protease inhibitor regimen to a single-tablet regimen containing elvitegravir, cobicistat, emtricitabine, and tenofovir DF in virologically suppressed HIV-1 infected patients.

Is PI the same as elvitegravir/cobicistat/emtricitabine/tenofovir DF?

PI is not the same as the combination product elvitegravir/cobicistat/emtricitabine/tenofovir DF. In the clinical trial NCT01475838, PI was studied as a comparator, and the trial evaluated switching from a PI-based regimen to the elvitegravir-containing single-tablet regimen.
