Summary

This trial is testing Tildacerfont to see if it can help adults with classic CAH reduce their steroid doses. The study will initially compare Tildacerfont to another treatment for several months, then allow all participants to use Tildacerfont for an extended period, with an optional longer-term extension. The goal is to find a safer way to manage CAH by lowering the need for high steroid doses. Tildacerfont has been studied in earlier trials for adults with classic congenital adrenal hyperplasia (CAH).

Who is the study for?
This trial is for adults over 18 with classic Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency. It's not open to those with other forms of CAH, a history of bilateral adrenalectomy, or hypopituitarism.
What is being tested?
The study tests if Tildacerfont can reduce the need for high doses of glucocorticoids in CAH patients. Participants will receive either Tildacerfont or a placebo and may continue treatment up to 240 weeks.
What are the potential side effects?
While specific side effects are not listed here, participants should be aware that they might experience unexpected reactions from taking Tildacerfont or the placebo during the trial.

Mechanism Of Action

Other Research
The most common treatments for Congenital Adrenal Hyperplasia (CAH) involve glucocorticoids and mineralocorticoids. Glucocorticoids work by replacing cortisol, a hormone that CAH patients cannot produce adequately, thereby reducing the overproduction of androgens and preventing adrenal crises. Mineralocorticoids help maintain salt balance and blood pressure, which are often disrupted in CAH. Tildacerfont, a CRF1 receptor antagonist, is being studied for its potential to reduce the need for high doses of glucocorticoids by inhibiting the CRF1 receptor, which plays a role in the stress response and adrenal hormone production. This is significant for CAH patients as it may help manage the condition with fewer side effects associated with long-term high-dose glucocorticoid therapy.
