Detailed Description

The study LCI699C2302 (LINC-4) is a multi-center, randomized, double-blind study to evaluate the safety and efficacy of osilodrostat in patients with Cushing's disease.

Enrolled patients were initially randomized to either osilodrostat or placebo, in a 2:1 ratio, for a 12-week double-blind period (Period 1). Randomization was stratified by history of pituitary radiation. After Week 12, all patients received open-label osilodrostat until the end of the Core phase at Week 48 (Period 2).

After Week 48, patients could join an optional 48 week extension period.

Description

Key inclusion criteria:

• Confirmed Cushing's Disease (CD) that is persistent or recurrent as evidenced by all of the following criteria being met (i.e., a, b and c):

  1. mUFC > 1.3 x ULN (Mean of three 24-hour urine samples collected preferably on 3 consecutive days, during screening after washout of prior medical therapy for CD (if applicable), confirmed by the central laboratory and available before Day 1), with ≥2 of the individual UFC values being > 1.3 x ULN.
  2. Morning plasma Adrenocorticotropic hormone (ACTH) above Lower Limit of Normal

  3. Confirmation (based on medical history) of pituitary source of excess

     ACTH as defined by any one or more of the following three criteria:

  i. Histopathologic confirmation of an ACTH-staining adenoma in patients who have had prior pituitary surgery. OR ii. Magnetic resonance imaging (MRI) confirmation of pituitary adenoma > 6 mm OR iii. Bilateral inferior petrosal sinus sampling (BIPSS) with either corticotropic-releasing hormone (CRH) or desmopressin (DDAVP) stimulation for patients with a tumor ≤ 6mm. The criteria for a confirmatory BIPSS test are any of the following: Pre-dose central to peripheral ACTH gradient > 2; Post-dose central to peripheral ACTH gradient > 3 after either CRH or DDAVP stimulation

• Patients that received glucocorticoid replacement therapy must have discontinued such therapy for at least seven days or 5 half-lives prior to screening, whichever is longer.
• Patients with de novo CD can be included only if they are not considered candidates for surgery (e.g., poor surgical candidates due to co-morbidities, inoperable tumors, patients who refuse to have surgical treatment, or surgical treatment is not available).

Key exclusion criteria:

• Patients with pseudo-Cushing's syndrome. This may be diagnosed by a normal late night salivary cortisol value collected during the screening period and after washout of prior CD medication.
• Patients with risk factors for QT corrected (QTc) prolongation or Torsade de Pointes, including:

patients with a baseline QT corrected (Fridericia QT formula) (QTcF) > 450 ms for males and QTcF > 460 ms for females; personal or family history of long QT syndrome; concomitant medications known to prolong the QT interval; patients with hypokalemia, hypocalcaemia, or hypomagnesaemia, if not corrected before pre-dose Day 1.

• Patients likely to require adrenalectomy, pituitary surgery, or radiation therapy during the placebo-controlled period (Weeks 1-12) for the treatment of severe hypercortisolism or pituitary tumor growth causing compression of the optic chiasm.
• Patients with compression of the optic chiasm due to a macroadenoma or patients at high risk of compression of the optic chiasm (tumor within 2 mm of optic chiasm).
• Patients who have a known inherited syndrome as the cause for hormone over secretion (i.e. Carney Complex, McCune-Albright syndrome, MEN-1, AIP).
• Patients with Cushing's syndrome due to ectopic ACTH secretion or ACTH independent (adrenal) Cushing's syndrome. Pregnant or nursing (lactating) women. 8. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 1 week after completion of dosing. Highly effective contraception methods include: A. Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. B. Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study drug. In case of bilateral oophorectomy, documentation is required (e.g. operative report, pelvic ultrasound or other reliable imaging method). C. Male sterilization (at least 6 months prior to screening). For female subjects on the study the vasectomized male partner should be the sole partner for that subject.

D. Combination of any two of the following (a+b or a+c, or b+c):

1. Use of oral*, injected, or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception
2. Placement of an intrauterine device (IUD) or intrauterine system (IUS)
3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository. *In the case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study drug. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (i.e., age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy, or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of child bearing potential.

The questionnaire consists of 12 items measured on a five point Likert-type scale assessing how often or how much each item has been related to the patient's Cushing's disease in the previous week. The raw score is calculated by summing the individual item scores prior to being standardized so that the total score ranges from 0 to 100. Increases from baseline are indicative of an improvement.	Baseline to Week 12 and 48, Week 12 to Week 36, Week 36 to Week 48.
Change From Baseline in Standardized Psychosocial Issues Score, Using Cushing Disease-specific Quality of Life Patient Reported Outcome (PRO) Assessment	The CushingQoL is a valid and reliable disease-specific QoL questionnaire which assesses health-related quality of life (HRQoL) in patients with Cushing's syndrome and has been validated in patients with Cushing's disease. The CushingQoL consists of questions reflecting dimensions of HRQoL related to physical aspects (e.g. 'I bruise easily'), psychological aspects (e.g. 'I am more irritable, I have sudden mood swings and angry outbursts'), and social aspects (e.g. 'I have had to give up my social or leisure activities due to my illness'). The questionnaire consists of 12 items measured on a five point Likert-type scale assessing how often or how much each item has been related to the patient's Cushing's disease in the previous week.

The CushingQoL consists of questions reflecting dimensions of HRQoL related to physical aspects (e.g. 'I bruise easily'), psychological aspects (e.g. 'I am more irritable, I have sudden mood swings and angry outbursts'), and social aspects (e.g. 'I have had to give up my social or leisure activities due to my illness'). The questionnaire consists of 12 items measured on a five point Likert-type scale assessing how often or how much each item has been related to the patient's Cushing's disease in the previous week. The raw score is calculated by summing the individual item scores prior to being standardized so that the total score ranges from 0 to 100. Increases from baseline are indicative of an improvement.	Baseline to Week 12 and 48, Week 12 to Week 36, Week 36 to Week 48.
Change From Baseline in EQ-5D-5L Utility Index	EQ-5D-5L Utility Index: The EQ-5D-5L questionnaire is a standardized measure of health status developed by the EuroQol Group in order to provide a simple, generic measure of health for clinical and economic appraisal. The EQ-5D-5L measures 5 items on mobility, self-care, usual activities, pain/discomfort, anxiety/depression, measured on 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. A utility index can be computed from the EQ 5D-5L descriptive system with utility scores ranging from -0.281 (worst imaginable health state) to 1 (best imaginable health state), with -0.281 representing an "unconscious" health state. A single index value is analyzed for the EQ-5D-5L score. An increase from baseline in the EQ-ED-5L utility index is indicative of an improvement.	Baseline to Week 12 and 48, Week 12 to Week 36, Week 36 to Week 48.
Change From Baseline in EQ-5D VAS	The EQ-5D-5L also includes a 20 cm vertical, VAS (visual analogue scale) with a scale of 0-100, with endpoints labeled 100='the best health you can imagine' and 0='the worst health you can imagine'. A single index value is analyzed for the EQ-5D-5L VAS score. An increase from baseline in the EQ-ED-5L VAS is indicative of an improvement.	Baseline to Week 12 and 48, Week 12 to Week 36, Week 36 to Week 48.
Change From Baseline in Beck Depression Inventory-II - Total Score Derived	The Beck Depression Inventory II (BDI-II) is a patient reported instrument that consists of 21 items designed to assess the intensity of depression in clinical and normal patients in the preceding two weeks. Each item is a list of four statements arranged in increasing severity about a particular symptom of depression. A global score ranges from 0 to 63 and is calculated with a higher score representing a greater level of depression. The following scoring guidelines for interpretation of BDI-II have been suggested (Smarr, 2011): Minimal range =0-13, Mild depression =14-19, Moderate depression =20-28 and Severe depression = 29-63. A reduction from baseline in BDI-II is indicative of an improvement.	Baseline to Week 12 and 48, Week 12 to Week 36, Week 36 to Week 48.
