A Phase II Trial to Assess the Efficacy and Safety of Pasireotide s.c. Alone or in Combination With Cabergoline in Patients With Cushing's Disease
This study is to assess whether pasireotide alone and combined with cabergoline will give
reliefs on patients with recurrent, persistent and newly diagnosed Cushing's disease. The
study will also assess study drug safety, the changes in Quality of Life and on clinical
signs and symptoms of Cushing's disease.

This study is to assess whether pasireotide alone and combined with cabergoline will give
reliefs on patients with recurrent, persistent and newly diagnosed Cushing's disease. The
study will also assess study drug safety, the changes in Quality of Life and on clinical
signs and symptoms of Cushing's disease. The study consists pasireotide-untreated patients at
screening and patients currently treated with maximal tolerated doses of pasireotide. Core
phase will consist of pasireotide-untreated patients at screening - this includes patients
who have never received pasireotide or patients who have received pasireotide sometime in the
past but it was not discontinued because of safety. These patients will start pasireotide at
0.6mg twice a day for 8 weeks. Should biochemical control not be achieved the dose will be
increased to 0.9mg twice a day. If biochemical control is still not achieved, cabergoline at
increasing dose will be added. Patients currently treated with maximal tolerated doses of
pasireotide monotherapy for at least 8 weeks at 0.3mg twice a day, 0.6mg twice a day or 0.9mg
twice a day, but still did not achieve biochemical control will add cabergoline at increasing
dose. After 35 weeks of treatment at core phase, patients will have the option to continue
study treatment in extension phase if pasireotide is not yet approved for commercial use
and/or reimbursed - if country reimbursement is applicable.

Inclusion criteria:
1. Written informed consent obtaine prior to screening procedures
2. Adult patients with confirmed diagnosis of ACTH-dependent Cushing's disease as
evidenced by all of the following:
1. The mean of three 24-hour urine samples collected within 2 weeks > 1xULN with 2
out of 3 samples >ULN
2. Morning plasma ACTH within the normal or above normal range
3. Either MRI confirmation of pituitary adenoma > 6 mm, or inferior petrosal sinus
gradient >3 after CRH stimulation for those patients with a tumor less than or
equal to 6 mm*. For patients who have had prior pituitary surgery, histopathology
confirming an ACTH staining adenoma *If IPSS had previously been performed
without CRH (e.g. with DDAVP), then a central to peripheral pre-stimulation
gradient > 2 is required. If IPSS had not previously been performed, IPSS with
CRH stimulation is required.
3. Patients with de novo Cushing's disease can be included only if they are not
considered candidates for pituitary surgery (e.g. poor surgical candidates, surgically
unapproachable tumors, patients who refuse to have surgical treatment)
4. Male or female patients aged 18 years or greater
5. Karnofsky performance status ≥ 60 (i.e. requires occasional assistance, but is able to
care for most of their personal needs)
6. Patients on medical treatment for Cushing's disease the following washout periods must
be completed before screening assessments are performed
- Inhibitors of steroidogenesis (ketoconazole, metyrapone): 1 week
- Pituitary directed agents: Dopamine agonists (bromocriptine, cabergoline) and
PPARγ agonists (rosiglitazone or pioglitazone): 4 weeks
- Octreotide LAR, Lanreotide SR and Lanreotide autogel: 14 weeks
- Octreotide (immediate release formulation): 1 week
- Progesterone receptor antagonist (mifepristone): 4 weeks
7. Patients can be considered to enter the trial if they meet any one of the following
criteria: 1) They are naive to pasireotide 2) They have received pasireotide in the
past and have been discontinued because of lack of efficacy (2 weeks for washout prior
to screening for patients treated with pasireotide subcutaneously and 12 weeks of
washout prior to screening for patients treated with pasireotide LAR) 3) Patients who
are on maximal tolerated dose but have not achieved biochemical control
8. Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, if they are using highly effective methods of contraception during
dosing and for 30 days after stopping study medication.
9. Male participants in the trial must agree to use a condom during intercourse, and not
to father a child during the study and for the period of 30 days following stopping of
the study treatment.
