Frequently asked questions about Avibactam

What is Avibactam?

Avibactam is a small molecule developed by Pfizer, Inc. (ticker PFE) as part of a combination antibacterial therapy for complicated infections, including bacterial infections. It is an investigational agent in clinical development and is being studied in combination with aztreonam under the name aztreonam-avibactam (ATM-AVI).

What is Avibactam used for in complicated infection?

Avibactam is being developed for complicated infections, including bacterial infections, as a component of combination antibacterial therapy. It is studied together with aztreonam as aztreonam-avibactam (ATM-AVI). It is investigational and has not been established as a marketed treatment for these infections.

Who makes Avibactam?

Avibactam is developed by Pfizer, Inc., which trades under the ticker PFE. Pfizer is the company associated with the clinical development program for aztreonam-avibactam (ATM-AVI), the combination in which avibactam is being studied for complicated infections.

What phase is Avibactam in?

Avibactam is in Phase 1 clinical development. The completed Phase 1 trial evaluated the safety and tolerability of aztreonam-avibactam (ATM-AVI). Avibactam is investigational and is not an approved product based on this development stage.

What clinical trials is Avibactam in?

Avibactam has been studied in the Phase 1 trial NCT01689207, titled "To Investigate the Safety and Tolerability of Aztreonam-Avibactam (ATM-AVI)." That trial enrolled 222 participants in the United Kingdom, was randomized, double-blind, and placebo-controlled, and has completed. It included healthy volunteers aged 18 years and older.

Is Avibactam the same as Avibactam (AVI)?

Yes. Avibactam is also referred to as Avibactam (AVI). Both names refer to the same small molecule being developed by Pfizer, Inc. (ticker PFE) as part of the aztreonam-avibactam (ATM-AVI) combination for complicated infections, including bacterial infections.
