We’ve been unlocking the potential of cortisol modulation for more than 25 years. We’re leading the way in the research and development of cortisol modulators, molecules that regulate cortisol activity at the glucocorticoid receptor (GR). To date, we have discovered more than 1,000 selective proprietary cortisol modulators. In 2012, we received FDA approval of a groundbreaking cortisol receptor blocker and the first approved treatment for hypercortisolism (Cushing’s syndrome). Today, our team and collaborators continue to unlock the possibilities of cortisol modulation as a way to treat serious diseases. With more than 30 ongoing studies across a wide range of disease areas, including endocrinology, oncology, metabolism, and neurology, we remain dedicated to advancing the possibilities of cortisol modulation. What began as a ripple of scientific truth is now poised to unleash a sea change of discovery representing a fundamental shift in the way we understand and treat disease.
