Do you have congenital adrenal hyperplasia? (CAH)

You're not alone. Learn about a new, no cost research study.

Right now, doctors at select centers in the U.S. are accepting participants for a new clinical research study.

This study is for a new investigational oral drug for CAH that aims to treat the underlying disease, and reduce the steroid burden on patients.

Congenital Adrenal Hyperplasia

Congenital adrenal hyperplasia (CAH) is a rare genetic disorder affecting the adrenal glands.

People with CAH have an impaired ability to produce cortisol, also known as “the stress hormone,” which has an effect on energy, blood pressure, and the body’s response to stress, illness and injury.

While chronic high dose steroids can effectively replace the body’s cortisol, they may cause a number of health challenges, including obesity, high blood pressure, osteoporosis and infertility.

Why participate?

If you qualify and choose to join the study, you will receive study-related:

  • Evaluations of your Congenital Adrenal Hyperplasia (CAH) condition by a local specialist.
  • Access to a new investigational oral drug for CAH only available through this study.
  • All study-related care, medical exams and study medication at no cost. You do not need insurance to participate.
  • Compensation for your time and travel to attend study visits.

Who is this study for?

If you are 18 years of age or older, and have been diagnosed with classic CAH, you may qualify to participate.

To see if you might qualify for the study, and to get connected with your local study center to discuss the study further, the next step is taking the pre-screening questionnaire.

What should I expect?

  • If you join the study, your participation will last about 10 weeks
  • There will be up to 5 scheduled visits to your local study center.
  • Some of these visits will involve an overnight stay, for which you will receive compensation and no-cost transportation to your local study center.
  • You will continue your current CAH treatment during the course of the study.
  • As with all clinical studies, your participation is completely voluntary and you may choose to leave the study at any time. Your study center will be able to discuss these visits with you in much more detail.

Frequently asked questions

What is the purpose of a clinical study?

Clinical studies (also called clinical trials) are used to learn about the safety and effectiveness of possible new medications, medical devices, and medical procedures. Although there are many types of clinical trials, all must conform to strict rules set by the U.S. Food and Drug Administration (FDA). These rules help protect the rights and safety of those who volunteer to take part in clinical trials.

Who is sponsoring the study?

The study is being sponsored by Spruce Biosciences, a biopharmaceutical company based in San Francisco.
