DUBLIN, Ireland and TREVOSE, Pa., Nov. 24, 2020 (GLOBE NEWSWIRE) — Strongbridge Biopharma plc, (Nasdaq: SBBP), a global commercial-stage biopharmaceutical company focused on the development and commercialization of therapies for rare diseases with significant unmet needs, today announced that secondary endpoint results from the Phase 3 SONICS study of RECORLEV™ (levoketoconazole) for the potential treatment of endogenous Cushing’s syndrome were published online in advance of print publication in the peer-reviewed journal, Pituitary, the official publication of the Pituitary Society and the Growth Hormone Research Society.
“People with Cushing’s syndrome often experience a variety of problematic signs, symptoms, and comorbidities related to excess cortisol, testosterone or both,” said Fredric Cohen, M.D., chief medical officer of Strongbridge Biopharma. “The SONICS study provided important evidence that RECORLEV treatment was associated with durable improvements in several of the more common and bothersome signs and symptoms of the syndrome, including those that most commonly affect women, such as hirsutism and acne, which are related to increases in testosterone produced by the adrenal glands.”
The manuscript, entitled “Levoketoconazole improves clinical signs and symptoms and patient-reported outcomes in patients with Cushing’s syndrome,” includes analyses demonstrating that treatment with RECORLEV led to significant improvements in Cushing’s syndrome signs and symptoms, patient-reported quality of life (QoL) outcomes, depression symptoms, and testosterone levels.
- Significant mean improvements from baseline were noted at end of the Maintenance phase (Month 6) for acne, hirsutism (females only), and peripheral edema.
- These improvements were observed as early as Day 1 of Maintenance for hirsutism, the end of Month 1 of Maintenance for acne, and Month 4 of Maintenance for peripheral edema.
- By Month 3 of Maintenance, significant mean improvements in patient-reported QoL outcomes were observed and by Month 6, symptoms of depression had improved.
- A reduction in mean free-testosterone in women, consistent with improvements in clinical signs of hyperandrogenism was observed, and a modest increase in mean free-testosterone in men was observed.
- RECORLEV was generally well-tolerated; the most commonly reported adverse events during the dose-titration and maintenance phases were nausea (32%) and headache (28%).

About Cushing’s Syndrome
Endogenous Cushing’s syndrome is a rare, serious and potentially lethal endocrine disease caused by chronic elevated cortisol exposure – often the result of a benign tumor of the pituitary gland. This benign tumor tells the body to overproduce high levels of cortisol for a sustained period of time, and this often results in undesirable physical changes. The disease is most common among adults between the ages of 30 to 50, and it affects women three times more often than men. Women with Cushing’s syndrome may experience a variety of health issues including menstrual problems, difficulty becoming pregnant, excess male hormones (androgens), primarily testosterone which can cause hirsutism (growth of coarse body hair in a male pattern), oily skin, and acne. Additionally, the internal manifestations of the disease are potentially life threatening. These include metabolic changes such as high blood sugar, or diabetes, high blood pressure, high cholesterol, fragility of various tissues including blood vessels, skin, muscle and bone, and psychologic disturbances such as depression, anxiety and insomnia. Untreated, the five-year survival rate is only approximately 50 percent.
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 mUFC 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 mUFC 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.
RECORLEV® (levoketoconazole) is an investigational cortisol synthesis inhibitor in development for the treatment of patients with endogenous Cushing’s syndrome, a rare but serious and potentially lethal endocrine disease caused by chronic elevated cortisol exposure. RECORLEV is the pure 2S,4R enantiomer of ketoconazole, a steroidogenesis inhibitor. RECORLEV has demonstrated in two successful Phase 3 studies to significantly suppress serum cortisol and has the potential to be a next-generation cortisol inhibitor.
The Phase 3 program for RECORLEV includes SONICS and LOGICS: two multinational studies designed to evaluate the safety and efficacy of RECORLEV when used to treat endogenous Cushing’s syndrome. The SONICS study met its primary and secondary endpoints, demonstrating a statistically significant normalization rate of urinary free cortisol at six months. The LOGICS study, which met its primary endpoint, is a double-blind, placebo-controlled randomized-withdrawal study of RECORLEV that is designed to supplement the long-term efficacy and safety information supplied by SONICS. The ongoing long-term open label OPTICS study will gather further useful information related to the long-term use of RECORLEV.
RECORLEV has received orphan drug designation from the FDA and the European Medicines Agency for the treatment of endogenous Cushing’s syndrome.
