Key inclusion & exclusion criteria

Inclusion criteria:
1. Written informed consent must be obtained before any assessment is performed.
2. Male or female patients aged 18 - 75 years

a. mUFC > 1.5 x ULN (Mean of three 24-hour urine samples collected within 14 days)

Primary Outcome(s)

Primary end point(s): Proportion of randomized patients in each arm with: mUFC = ULN at the end of 8 weeks of randomized withdrawal (Week 34), and were neither discontinued, nor had LCI699 dose increase above the level at week 26 during the randomized withdrawal period.

Main Objective: To compare the complete response rate at the end of the 8-week period of randomized withdrawal (Week 34) between patients randomized to continued LCI699 therapy vs. placebo.

Secondary Objective: To assess the complete response rate at the end of individual dose-titration and treatment with LCI699 in the initial single-arm, open label period (Week 24).
1. Compare the time-to-last control of mUFC during the randomized withdrawal period between patients randomized to continued LCI699 therapy and placebo.
2. Assess the complete, partial, and overall response rate at Week 12, Week 24 and Week 48.
3. Assess the change in mUFC during the core and extension periods of the study.
4. To assess the change in cardiovascular-related parameters associated with Cushing’s disease during the core period of the study.
5. Change in Patient-Reported Outcomes (Health- Related Quality of Life) during the core period of the study
6. Change from baseline in the physical features of Cushing’s disease by photography at Week 12, 24, 34, and 48.
7. Percent change from baseline in bone mineral density by DEXA scan at the lumbar spine and total hip at Week 48.
Other objectives may apply.

• Actual and percentage change from the randomization (Week 26) to the end of randomized withdrawal period (Week 34), or the last measurement available prior to early discontinuation, whichever occurs earlier (see bullet above for individual parameters).
5. • Change in standardized score of CushingQoL, Beck Depression Inventory-II, and EQ-5D-5L, from baseline to Week 24 and Week 48.
• Change in standardized score of CushingQoL, Beck Depression Inventory-II, and EQ-5D-5L, from the randomization (Week 26) to the end of randomized withdrawal period (Week 34), or the last measurement prior to early discontinuation, whichever occurs earlier.
6. Mean change from baseline to Week 12, 24, 34, and 48 in each of the following clinical signs of Cushing’s disease by photography: facial rubor, hirsutism, striae, supraclavicular fat pad, dorsal fat pad, proximal muscle wasting (atrophy), central (abdominal) obesity, and ecchymoses (bruises).
