About the SONICS Study

SONICS is an open-label, Phase 3 study of RECORLEV as a treatment for endogenous Cushing’s syndrome that enrolled 94 patients at centers in North America, Europe and the Middle East. Following a screening phase, SONICS has three treatment phases:

(1) Dose Titration Phase: Patients started RECORLEV at 150 mg twice daily (300 mg total daily dose) and titrated in 150 mg increments with the goal of achieving a therapeutic dose – a dose resulting in mean UFC normalization – at which point titration was stopped; (2) Maintenance Phase: The dose was fixed and should not have been changed other than for safety reasons or loss of efficacy. At the end of the six-month maintenance phase, the mean UFC response rate was measured; and (3) Extended Evaluation Phase: Patients continued on RECORLEV for another six months to evaluate long-term safety and tolerability and explore efficacy durability.

About Endogenous Cushing’s Syndrome

Endogenous Cushing’s syndrome (CS) is a rare but serious and potentially lethal endocrine disease caused by chronic elevated cortisol exposure. Most people with CS have a variety of signs and symptoms – many of which, when they occur by themselves, are common and do not necessarily point to an underlying disease; this makes recognition of CS difficult. Common presenting symptoms include weight gain or obesity, fatigue, muscle weakness, headaches, mood or sleep disturbances, facial rounding or redness, excess body hair growth in women or baldness in men, thinned skin with stretch marks, easy bruising and other skin changes including acne, mood or sleep disturbances and irregular periods or loss of libido. Patients are often found by their doctors to have new-onset or worsening of high blood pressure, abnormal levels of blood lipids, such as cholesterol, polycystic ovaries and abnormal blood glucose or diabetes. People with uncontrolled disease are seriously ill and have a 2- to 4-fold higher mortality rate than age- and gender-matched controls, mainly due to metabolic and cardiovascular complications. Treatment options for CS include surgery, radiation therapy, and medical treatment. CS most commonly affects adults ages 20-50 and is more prevalent in females, accounting for about 70 percent of all cases.
