The LINC 4 study demonstrated superiority of ISTURISA® (osilodrostat) over placebo in achieving cortisol control during the 12-week, double-blind, randomized phase (77% vs 8%, P<0.0001).
ISTURISA provided rapid and sustained control of cortisol secretion in the majority of patients throughout the 48-week core phase of the study.
LEBANON, N.J.–(BUSINESS WIRE)– Recordati Rare Diseases Inc. announce today the publication of positive results from the Phase III LINC 4 study of ISTURISA in The Journal of Clinical Endocrinology & Metabolism.1 These data reinforce ISTURISA as an effective and well-tolerated oral therapy for patients with Cushing’s disease. ISTURISA is indicated in the United States for the treatment of adult patients with Cushing’s disease,2 a rare and debilitating condition of hypercortisolism that is caused by a pituitary adenoma.3
The LINC 4 study augments the efficacy and safety data for ISTURISA in patients with Cushing’s disease, confirming the results from the Phase III LINC 3 study. This study in 73 adults is the first Phase III study of a medical treatment in patients with Cushing’s disease to include an upfront, randomized, double-blind, placebo-controlled period during which 48 patients received ISTURISA and 25 received placebo for the first 12 weeks, followed by an open-label period during which all patients received ISTURISA until week 48; thereafter, patients could enter an optional extension phase.
Key findings published in the manuscript entitled ‘Randomised trial of osilodrostat for the treatment of Cushing’s disease’ include:1
“These results show convincingly that osilodrostat is an effective treatment for Cushing’s disease,” said Peter J. Snyder MD, Professor of Medicine at the University of Pennsylvania. “Osilodrostat rapidly lowered cortisol excretion to normal in most patients with Cushing’s disease and maintained normal levels throughout the core phase of the study. Importantly, this normalization was accompanied by improvements in cardiovascular and metabolic parameters, which increase morbidity and mortality in Cushing’s disease.”
“These compelling data build on the positive Phase III LINC 3 study, published in The Lancet Diabetes & Endocrinology in 2020,4 demonstrating that ISTURISA enables most patients with Cushing’s disease to gain rapid control of their cortisol levels, which in turn provides relief from a host of undesirable symptoms,” said Alberto Pedroncelli, Clinical Development & Medical Affairs Lead, Global Endocrinology, Recordati AG. “Recordati Rare Diseases is committed to improving the lives of patients with this rare, debilitating and life-threatening condition. I would like to thank everyone who has contributed to LINC 4 and the LINC clinical program.”
“Suffering from Cushing’s disease has affected every system in my body, including my mental health. For me, the only thing worse than receiving my initial diagnosis of Cushing’s disease was receiving the diagnosis a second time after what was considered a ‘successful’ surgical treatment,” said Alicja D., a patient being successfully treated for Cushing’s Disease using ISTURISA. “My current medical treatment has contributed greatly to the stability of my overall wellness and my hope for continued relief moving forward.”
Important safety information for ISTURISA
Indications and usage
ISTURISA (osilodrostat) is a cortisol synthesis inhibitor indicated for the treatment of adult patients with Cushing’s disease for whom pituitary surgery is not an option or has not been curative.

About Cushing’s disease
Cushing’s disease is a form of Cushing’s syndrome, in which chronically elevated cortisol levels is triggered by a pituitary adenoma secreting excess adrenocorticotropic hormone (ACTH).5 It is a rare, serious and difficult-to-treat disease that affects approximately one to two patients per million per year. Prolonged exposure to elevated cortisol levels is associated with considerable morbidity, mortality and impaired QoL as a result of complications and comorbidities.6 Normalization of cortisol levels is therefore a primary objective in the treatment of Cushing’s disease.7
About LINC 4
LINC 4 is a large randomized, double-blinded, multicenter, 48-week trial with an initial 12-week placebo-controlled period to evaluate the safety and efficacy of osilodrostat in patients with Cushing’s disease. The primary endpoint in the LINC 4 trial is the proportion of patients randomized to ISTURISA and placebo, separately, with an mUFC ≤ULN at the end of the 12-week, placebo-controlled period. The key secondary endpoint is the proportion of patients in both arms combined with an mUFC ≤ULN after 36 weeks. LINC 4 involved 73 patients with persistent or recurrent Cushing’s disease or those with de novo disease who were not candidates for surgery.
ISTURISA is a cortisol synthesis inhibitor that works by inhibiting 11-beta-hydroxylase, an enzyme responsible for the final step of cortisol biosynthesis in the adrenal gland. ISTURISA is available as 1 mg, 5 mg and 10 mg film-coated tablets. Please see prescribing information for detailed recommendations for the use of this product.2 In March 2020, the FDA granted marketing authorization for ISTURISA in the United States.
