Study of the Efficacy and Safety of Pasireotide s.c. +/- Cabergoline in Patients With Cushing's Disease
Study of the Efficacy and Safety of Pasireotide s.c. +/- Cabergoline in Patients With Cushing's Disease
The main purpose of this prospective, multicenter, open-label phase II study, was to evaluate
 the efficacy and safety of pasireotide alone or in combination with cabergoline in patients
 with Cushing's disease.
This was an open-label, multi-center, international, non-comparative study with adult
 patients with confirmed diagnosis of Cushing's disease. Given the fact that CD patients may
 need a multimodality treatment approach, the trial design aimed to mimic CD treatment by
 using a medical stepwise approach. Therefore, the whole patient population started treatment
 with Pasireotide and only in patients within this population who did not achieve biochemical
 control, cabergoline was added.

 The whole patient population had never received pasireotide or had received it in the past
 (reasons of discontinuation not related to safety).

 Core Phase

 -  Pasireotide naïve patients started pasireotide monotherapy at the dose of 0.6 mg s.c.
 bid. If at the end of the 8 week treatment period, the biochemical control was not
 achieved and the 0.6mg bid dose was well tolerated, the pasireotide dose was increased
 to 0.9mg bid. If the 0.9mg bid dose of pasireotide did not lead to biochemical control,
 cabergoline was added with a starting dose of 0.5mg qd. If the combination dose of 0.9mg
 bid of pasireotide plus 0.5mg qd cabergolinedid not achieve biochemical control, the
 cabergoline dose will be increased to 1.0mg qd.

 -  Patients who were currently being treated with maximal tolerated doses of pasireotide
 monotherapy for at least 8 weeks at screening without achieving normal mUFC, entered the
 study with a combination therapy starting with cabergoline 0.5mg qd.

 Extension Phase

 • After 35 weeks of treatment in core phase, patients had the option to continue study
 treatment if pasireotide was not yet approved for commercial use and/or reimbursed - if
 country reimbursement was applicable - in each respective country, or until 31st December
 2017, or once an applicable roll over protocol became available, or whichever occurred first.

 Novartis had a local transition plan in order to ensure that all trial patients had access to
 the study medication without any delay in their treatment
Inclusion criteria:

 1. Written informed consent obtained prior to screening procedures

 2. Adult patients with confirmed diagnosis of ACTH-dependent Cushing's disease as
 evidenced by all of the following:

 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 was required. If IPSS had not previously been performed, IPSS with
 CRH stimulation was required.

 3. Patients with de novo Cushing's disease could only be included only if they were not
 considered candidates for pituitary surgery (e.g. poor surgical candidates, surgically
 unapproachable tumors, patients who refused to have surgical treatment)

 4. Male or female patients aged 18 years or greater

 5. Karnofsky performance status ≥ 60 (i.e. required occasional assistance, but was able
 to care for most of their personal needs)

 6. Patients on medical treatment for Cushing's disease the following washout periods must
 have been completed before screening assessments were performed

 -  Inhibitors of steroidogenesis (ketoconazole, metyrapone): 1 week

 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 could have been considered to enter the trial if they met any one of the
 following criteria: 1) They were naive to pasireotide 2) They had 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 were on maximal tolerated dose but had not achieved biochemical control

 8. Women of child-bearing potential, defined as all women physiologically capable of
 becoming pregnant, if they were using highly effective methods of contraception during
 dosing and for 30 days after stopping study medication.

 9. Male participants in the trial must have agreed to use a condom during intercourse,
 and not to father a child during the study and for the period of 30 days following
