E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to demonstrate that daily administration of mifepristone in subjects with Cushing's syndrome caused by ectopic ACTH secretion will improve the glucocorticoid-dependent parameters of blood pressure and/or glucose tolerance. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess the impact of long-term administration of mifepristone on other glucocorticoid-dependent parameters, and the safety of the agent. The clinical and biochemical features and safety parameters which will be evaluated are detailed in protocol. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects will be included if they have ALL of the three following criteria:
1. Hypercortisolism from Cushing’s syndrome caused by ectopic ACTH secretion confirmed by: - Inferior petrosal sinus sampling (IPSS) with a central to peripheral ACTH ratio of less than 2.0 before CRH administration and less than 3.0 after CRH administration. - or biopsy with ACTH immunoreactivity. - or presence of a tumor evidenced by imaging combined with both a negative CRH test and a negative 8 mg dexamethasone suppression test. No major change in tumor status/anti-tumor therapy should be expected during the study
AND 2. Glucose intolerance AND/OR hypertension that is considered to be caused or worsened by the hypercortisolism: o Diabetes defined by fasting plasma glucose level ≥ 7.0 mmol/l (126 mg/dl) or 2-hour glucose plasma level after 75 g OGTT ≥ 11.1 mmol/l (200 mg/dl) or treated diabetes or glucose intolerance defined by: fasting plasma glucose values between 5.5 mmol/l (100 mg/dl) and 7.0 mmol/l (126 mg/dl) or 2-hour glucose plasma level after 75 g OGTT ≥ 7.8 mmol/l (140 mg/dl) ) and < 11.1 mmol/l (200 mg/dl) Prior to study entry, fasting blood sugar must be less than 11.1 mmol/l (200 mg/dl) for at least two weeks o Hypertension defined by systolic BP ≥ 140 mm Hg and/or diastolic BP ≥ 90 mm Hg Prior to study entry, BP must be less than 180/110 mmHg for at least two weeks or treated hypertension
AND 3. At least one of the following symptoms attributable to the Cushing’s syndrome: o Body weight increase or truncal obesity o Depression or treated depression or psychiatric disorder o Fatigue o Proximal muscle weakness o Hirsutism o Hypokalemia o Bruising o Violaceous striae o In men, gynecomastia or libido decrease o Impaired cognition or memory o Hyperpigmentation o Amenorrhea o Osteopenia or osteoporosis
In addition, the following criteria should be met: - Written informed consent to participate in the study - Female subjects should be sterilized, post-menopausal, sexually inactive or willing to use barrier methods of contraception throughout the study. - Subject willing to return to investigational site during the full course of the study - Age in the range of 18 to 75 years inclusive |
|
E.4 | Principal exclusion criteria |
- Evidence for Cushing’s disease as judged by positive inferior petrosal sinus sampling or a lesion on pituitary MRI with positive CRH test - Suspected or known adrenocortical cancer or adenomas, as judged by ACTH values < 10 pg/ml and adrenal mass - Subjects with cyclic Cushing’s syndrome defined by at least 3 measurements of Urinary Free Cortisol over the previous two months without normal values. - Children (age less than 18) and subject of more than 75 years of age - Pregnant or lactating women. A urinary pregnancy test will be performed in women of childbearing potential unless they have a history of menopause prior to Cushing’s syndrome or hysterectomy - Life expectancy less than three months - Severe uncontrolled diabetes - Grade III or IV hypertension - Recent (less than two weeks prior to inclusion) initiation of corrective treatments for diabetes, hypertension or depression - Clinically significantly impaired cardiovascular function (e.g. stage IV cardiac failure) - Severe liver disease (liver enzymes ≥ 3 x the institutional upper limit of normal range) - Severe renal impairment (serum creatinine ≥ 2.2 mg/dl or creatinine clearance < 30 ml/min) - Uncontrolled severe active infection - In women, known endometrial cancer, history of endometrial hyperplasia or vaginal bleeding of unknown cause - Recent (less than two weeks prior to inclusion) initiation of or significant change in dose of anti-tumor therapy - Treatment with approved or experimental steroidogenesis inhibitors, adrenolytic agents or somatostatin analogues within four weeks of admission - Plasma mitotane concentration > 5 µg/ml - Impaired mental capacity or markedly abnormal psychiatric evaluation that precludes informed consent - Body weight over 136 kg, which is the limit for the tables used in the scanning areas |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Assessment of primary efficacy data will be based on: Blood pressure (supine blood pressure) and glucose tolerance (fasting glucose in diabetes and 2-hour OGTT in glucose intolerance) measured at visit P and additional visits M1 to M3 as applicable.
