Frequently asked questions about Naloxegol

What is naloxegol used for?

Naloxegol is being studied for opioid induced constipation and drug induced constipation. It is a small molecule developed by AstraZeneca PLC (ticker AZN) and is currently in Phase 1 clinical development. The available trials enrolled healthy volunteers to evaluate its pharmacokinetics and bioequivalence.

What does naloxegol target?

Naloxegol targets OPRM1, the mu opioid receptor, and acts as an antagonist. By blocking this receptor, it is designed to counteract opioid-induced slowing of the gastrointestinal tract, which is the basis for its investigation in opioid induced constipation and drug induced constipation.

Who makes naloxegol?

Naloxegol is developed by AstraZeneca PLC, which trades under the ticker AZN. The company is responsible for the clinical program, including the Phase 1 trials conducted in the United Kingdom and the United States.

What phase is naloxegol in?

Naloxegol is in Phase 1 clinical development. It has completed one Phase 1 trial and is not approved for any indication. The program includes a completed bioequivalence study and a completed drug interaction study, both in healthy volunteers.

What clinical trials is naloxegol in?

Naloxegol has been evaluated in two completed Phase 1 trials: NCT01623609, a bioequivalence study in healthy volunteers with opioid induced constipation, and NCT01594619, which investigated the effects of diltiazem on naloxegol pharmacokinetics in healthy volunteers with drug induced constipation.
