Frequently asked questions about eneboparatide

What is eneboparatide used for in chronic hypoparathyroidism?

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 targets the parathyroid hormone (PTH) pathway. It is a peptide-based agent designed to address the hormonal deficiency characteristic of chronic hypoparathyroidism. By engaging this pathway, it aims to restore physiological functions that depend on adequate parathyroid hormone activity.

Who is developing eneboparatide?

Eneboparatide is being developed by AstraZeneca PLC, a multinational pharmaceutical company listed on major stock exchanges under the ticker symbol AZN. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational therapy for 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. This randomized, double-blind, placebo-controlled study is assessing the safety and efficacy of eneboparatide in patients with chronic hypoparathyroidism. The trial is active but not recruiting, with an enrollment target of 165 participants across multiple countries.

Is eneboparatide the same as AZP-3601?

Yes, eneboparatide is also known as AZP-3601. The Phase 3 clinical trial NCT05778071, which evaluates the safety and efficacy of eneboparatide in patients with chronic hypoparathyroidism, refers to the drug by this alternative name, confirming that both names identify the same investigational therapy.
