August 28, 2020 updated by: Novartis Pharmaceuticals

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

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.

Detailed Description

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

Intervention / Treatment
EXPERIMENTAL: pasireotide +/- cabergoline
pasireotide alone or with cabergoline
The trial consisted of Pasireotide-untreated patients who started pasireotide 0.6mg twice a day for 8 weeks. If biochemical control was not achieved by the end of the 8 weeks, and the 0.6mg dose is well-tolerated, the dose was increased to 0.9mg twice a day for another 8 weeks. If biochemical control is not achieved, cabergoline was added and patients began combination treatment with cabergoline at the starting dose of 0.5mg once a day for 8 weeks. If biochemical control is still not achieved at the end of the third 8 week period, the dose of cabergoline was increased to 1.0mg once a day. Patients could also immediately start the combination treatment by adding cabergoline 0.5mg once a day at study entry to their current maximal tolerated dose of pasireotide. Patients continued with the combination treatment for 8 weeks. If biochemical control was not not achieved by the end of the 8 week period, the dose of cabergoline was increased to 1mg once a day.

Raw scores were obtained for the 12 items using the following scoring: 1) always or very much, 2) often or quite a bit, 3) sometimes or somewhat, 4) rarely or very little, 5) never or not at all. Then the standardized score, Y, was calculated for each patient as follows: Y = 100* (X - n) / n*5 - n*1) = 100 * (X - n) / 4*n where X denoted the raw score and n the number of questions answered by the patient. The higher the score, the better the QoL. The best possible standardized score was 100 and the worst possible standardized score was 0

Mean Scores of SF-12v2 Domain Scores at Week 17 and 35
Time Frame: Baseline, week 17 and 35
SF-12v2 General Health Survey is a general patient reported outcome instrument over time. It is scored to provide eight health domain scores (Bodily Pain (BP), General Health (GH), Physical Functioning (PF), Role-Physical (RP), Social Functioning (SF), Role-Emotional (RE), Vitality (VT) and Mental Health (MH)). These eight domain scores can be combined to form two summary scores reflecting overall physical and mental health: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). The analyses reported here focus on PCS and MCS scores. The domain scores use a norm-based score, which standardizes the scores with respect to the mean and standard deviation of a nationally representative sample of United States (US) adults. These are the scores on the original scale which have not been transformed in any way. The possible range of scores is 0 to 100, with higher scores representing better outcomes.
