Summary

This trial is testing a new medication called crinecerfont in adults with a genetic condition that affects hormone production. The study aims to see if crinecerfont can help balance their hormone levels and improve their symptoms. Participants will take the medication for several months, with an option to continue longer.

Who is the study for?
Adults with classic Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency can join. They must be on stable CAH medication, agree to use contraception if they can have children, and follow study rules. Excluded are those with unstable conditions, hypersensitivity to similar drugs, certain medical histories like cancer or chronic glucocorticoid therapy needs.
What is being tested?
The trial is testing Crinecerfont against a placebo for CAH over 24 weeks in a double-blind setup where neither the participants nor the researchers know who gets what. After this phase, there's an open-label period where everyone receives Crinecerfont for up to three years.
What are the potential side effects?
While specific side effects of Crinecerfont aren't listed here, common ones may include reactions at the injection site, hormonal imbalances leading to mood changes or skin issues, and potential risks associated with long-term hormone therapy.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Congenital Adrenal Hyperplasia (CAH) include glucocorticoids and CRF1 receptor antagonists like Crinecerfont. Glucocorticoids replace deficient cortisol and suppress excess adrenocorticotropic hormone (ACTH) production, thereby reducing the overproduction of androgens. CRF1 receptor antagonists block the corticotropin-releasing factor 1 receptor, reducing ACTH release from the pituitary gland. This helps manage the hormonal imbalances in CAH patients, which is essential for controlling symptoms and improving long-term health outcomes.
