The Unmet Need
For millions of women, endometriosis means years of chronic pelvic pain, fatigue, digestive problems, and the emotional toll of anxiety and depression, often dismissed or misdiagnosed for 7 to 10 years. When a diagnosis finally comes, the available treatments can only be prescribed for 12 months at a time due to serious side effects, including bone density loss and suicidal ideation.

Our Approach
Targeting the Root Cause, Not the Symptoms
Sur180 Therapeutics is pioneering a new direction by targeting the hypothalamic-pituitary-adrenal (HPA) axis, also known as the stress axis, rather than the traditional gonadal hormonal pathway.
​
Our research has identified that the corticotropin-releasing hormone receptor 1 (CRHR1) plays a fundamental role in inflammation, pain, and the development of endometriosis lesions. By blocking this receptor with a non-hormonal, orally available drug candidate, we aim to reduce pain, suppress inflammation within lesions, and reduce adhesions, without disrupting reproductive hormones or fertility.
By repositioning a molecule already known to be safe, Sur180 significantly reduces developmental costs compared to a novel compound. This translates into a more capital-efficient path to market and potential savings for health insurers and patients, increasing the commercial attractiveness of our approach.
