Frequently asked questions about eneboparatide

What is eneboparatide used for?

Eneboparatide is an investigational small molecule being developed for the treatment of chronic hypoparathyroidism, a condition where the parathyroid glands produce insufficient parathyroid hormone. It is currently in Phase 3 clinical development and has not been approved by regulatory authorities.

What does eneboparatide target?

Eneboparatide is a peptide-based therapeutic, classified as a -tide (peptide) agent. It is designed to act on pathways related to parathyroid hormone regulation, though its specific molecular target is not disclosed in the available clinical trial information.

Who makes eneboparatide?

Eneboparatide is being developed by AstraZeneca PLC, a global biopharmaceutical company listed on the stock exchange under the ticker symbol AZN. The company is conducting a Phase 3 clinical trial to evaluate the drug's safety and efficacy in patients with chronic hypoparathyroidism.

What phase is eneboparatide in?

Eneboparatide is currently in Phase 3 clinical development. It is an investigational drug, meaning it has not yet received regulatory approval and is still being studied in clinical trials to assess its safety and effectiveness for treating chronic hypoparathyroidism.

What clinical trials is eneboparatide in?

Eneboparatide is being evaluated in a Phase 3 clinical trial registered as NCT05778071, titled 'Evaluation of the Safety and Efficacy of Eneboparatide (AZP-3601) in Patients With Chronic Hypoparathyroidism.' This randomized, double-blind, placebo-controlled study has an enrollment of 165 participants and is active but not recruiting.

Is eneboparatide the same as AZP-3601?

Yes, eneboparatide is also known as AZP-3601. The Phase 3 clinical trial NCT05778071 explicitly refers to the drug as 'Eneboparatide (AZP-3601),' confirming that these names refer to the same investigational compound being developed for chronic hypoparathyroidism.
