Key inclusion & exclusion criteria

Inclusion criteria:
•Male or female patients aged 18 years or greater
•Patients with confirmed diagnosis of ACTH-dependent Cushing’s disease, as evidenced by (1) mean UFC from two 24-hour urinary collections at least two times the upper limit of the laboratory normal range collected within 2 weeks; (2) morning plasma ACTH within the normal or above normal range; (3) either MRI confirmation of pituitary macroadenoma (greater than or equal to 1 cm) or inferior petrosal sinus gradient >3 after corticotrophin-releasing hormone (CRH) or for patients who have had prior pituitary surgery, documentation confirming an ACTH staining adenoma (an MRI is also required). This diagnosis must be verified within 2 months prior to study entry
•Patients with de novo Cushing’s disease can be included only if they are not considered candidates for pituitary surgery (poor surgery candidates, surgically unapproachable tumors, patients who refuse to have surgical treatment)
•Karnofsky performance status =60 (i.e. requires occasional assistance, but is able to care for most of his personal needs)
•For patients on medical treatment for Cushing’s disease the following washout periods must be completed before baseline efficacy assessments are performed
- Inhibitors of steroidogenesis – ketoconazole, metyrapone, rosiglitazone: 1 week
- Dopamine agonists – bromocriptine, cabergoline: 4 weeks
- Octreotide LAR and Lanreotide autogel: 8 weeks
- Lanreotide SR: 4 weeks
- Octreotide – immediate release formulation: 1 week
•Patients with a known history of impaired fasting glucose or Diabetes Mellitus (DM) may be included, however blood glucose and antidiabetic treatment must be monitored closely throughout the trial and adjusted as necessary

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion criteria:
Patients who:
•received pituitary irradiation
•were treated with mitotane during the last 6 months
•with compression of the optic chiasm causing any visual field defect
•with Cushing’s syndrome due to ectopic ACTH secretion
•with hypercortisolism secondary to adrenal tumors or Nodular (primary) bilateral adrenal hyperplasia
• have a known inherited syndrome as the cause for hormone over secretion (i.e. Carney Complex, McCune-Albright syndrome, MEN-1)
•with a diagnosis of glucocorticoid-remedial aldosteronism (GRA)
•are not biochemically euthyroid
•have undergone major surgery within 1 month
•with symptomatic cholelithiasis
• Diabetic patients on antidiabetic medications whose fasting blood glucose is poorly controlled as evidenced by HbA1c >8%
•with abnormal coagulation (PT or PTT elevated by 30% above normal limits)
•receiving anticoagulants that affect PT or PTT
•have congestive heart failure (NYHA Class III or IV), unstable angina, sustained ventricular tachycardia, symptomatic bradycardia, advanced heart block, history of acute MI less than one year prior to study entry or clinically significant impairment in cardiovascular function
•with liver disease such as cirrhosis, chronic active hepatitis, or chronic persistent hepatitis, or patients with ALT/AST more than 2 X ULN, serum creatinine >2.0 X ULN, serum bilirubin >2.0 X ULN, serum albumin >1.5 X ULN
•with WBC <3 X 109/L; Hgb <13 g/dL for males and <12 g/dL for females; PLT <100 X 109/L
•have any current or prior medical condition that can interfere with the conduct of the study or the evaluation of its results in the opinion of the investigator or the sponsor’s medical monitor
• Female patients who are pregnant or lactating, or are of childbearing potential and not practicing a medically acceptable method for birth control. Female patients must use barrier contraception with condoms. If oral contraception is used, the patient must have been practicing this method for at least two months prior to enrollment and must agree to continue the oral contraceptive throughout the course of the study and for one month after the last dose of study drug. Male patients who are sexually active are required to use condoms during the study and for 1 month afterwards
•with the presence of active or suspected acute or chronic uncontrolled infection

Health Condition(s) or Problem(s) studied

Cushing’s disease is rare disease that is caused by an adrenocorticotropic hormone (ACTH) secreting pituitary adenoma. The elevated ACTH secreted by these tumors stimulates the adrenal glands to produce excess cortisol, leading to the subsequent development of the clinical signs and symptoms of hypercortisolism. Cushing's disease is associated with severe morbidity and premature mortality and most commonly affects adults aged 20-50, primarily females
MedDRA version: 8.1 Level: LLT Classification code 10011651 Term: Cushing's disease

Primary Outcome(s)

Secondary Objective: TO ASSESS
• censor-adjusted response
• pooled dose response
• time to response
• response by dose group
• normalization of UFC at 6 months
• effect on plasma ACTH and serum cortisol
• improvement in clinical signs: blood pressure, body mass index, waist circumference and weight reduction
•improvement in clinical symptoms: depression, facial rubor, buffalo hump, supraclavicular and dorsal fat pads, hirsutism, striae, muscle strength, bone density and body composition
• effect on Quality of Life
• effect on tumor size (MRI)

•determine the pharmacokinetics of pasireotide s.c. b.i.d.
•identify patient related factors that may affect the PK, PD or safety/tolerability of pasireotide after s.c. b.i.d. dosing
•explore potential pharmacokinetic/pharmacodynamic relationships
•evaluate the safety and tolerability of pasireotide s.c. in patients with Cushing’s disease
EXPLORATORY OBJECTIVE
•to compare pasireotide 600 µg s.c and 900 µg s.c. b.i.d. dose response

Primary end point(s): Proportion of patients in each independent treatment arm with <1.5 X ULN and >50% reduction in UFC from baseline, at month 6

Main Objective: To assess the efficacy in terms of response to pasireotide 600 µg s.c. b.i.d. and 900 µg s.c. b.i.d. independently in patients with Cushing’s disease as measured by UFC =1.5 X ULN and =50% reduction of urinary free cortisol (UFC) from baseline after 6 months of treatment
