Frequently asked questions about NaxRedy

What is NaxRedy?

NaxRedy is an investigational small molecule medicine developed by Pfizer, Inc. (ticker PFE). It is being studied in a Phase 1 clinical program, and the specific therapeutic indication has not been disclosed. NaxRedy is also written as NaxRedy ™.

Who makes NaxRedy?

NaxRedy is developed by Pfizer, Inc., which trades under the ticker PFE. Pfizer is the sponsor of the clinical program studying the asset.

What phase is NaxRedy in?

NaxRedy is in Phase 1 clinical development. It is an investigational asset and has not been approved by the FDA. One Phase 1 trial has been completed, and no trials are currently active.

What clinical trials is NaxRedy in?

NaxRedy has been studied in one completed Phase 1 trial, NCT05264493, titled Bioavailability Study of Naloxone 5 Milligrams (mg) Intramuscular (IM) Autoinjector. The trial enrolled 13 participants in the United States, used an active-controlled, randomized design, and was conducted in healthy volunteers aged 18 years and older.

Is NaxRedy the same as NaxRedy ™?

Yes. NaxRedy and NaxRedy ™ refer to the same Pfizer asset. NaxRedy ™ is the trademarked styling of the name, so searches for either form point to the same investigational small molecule in Phase 1 development.

What is NaxRedy used for?

NaxRedy is an investigational small molecule in Phase 1 development, and its intended therapeutic indication has not been disclosed. The completed Phase 1 trial, NCT05264493, evaluated bioavailability of a naloxone 5 mg intramuscular autoinjector in healthy volunteers rather than in a patient population.
