Clinical Trial Summary

This exploratory study is a proof of concept study to determine whether LCI699 can safely reduce the level of urinary free cortisol in patients with Cushing's disease. In addition, this study evaluated the long term efficacy and safety of LCI699 including an additional 12 week of treatment followed by a 12 month long term optional extension. A second extension provided patients who were clinically benefitting from LCI699 an opportunity to continue to have access to the drug until LCI699 was commercially available and reimbursed or through the availability of a local access program.


Description:

The Primary objective of this study was to assess the effect of 10-week treatment osilodrostat on 24 hour urine free cortisol (UFC) in patients with Cushing's disease. The study consisted of a screening period of up to 60 days (to allow an adequate washout period for any medications that modified cortisol levels), a 10-14-day baseline period, a 10-week sequential dose escalation treatment period and a 14-day washout period followed by a Study Completion evaluation approximately 14 days after the last drug administration. Twelve patients were recruited and completed Part l of the study. Eligible patients were dosed at 2 mg b.i.d for the first two weeks, the dose could then be increased every two weeks as necessary (to doses of 5, 10, 20 and 50 mg b.i.d). If at anytime, the subject's UFC was < Upper Limit of Normal (ULN), dose escalation was halted and the subject remained on the current, efficacious dose through Week 10, with continued monitoring of UFC responses every 2 weeks to allow continued dose adjustments if necessary. If at any time the subject experienced side effects which were either intolerable or met dose adjustment criteria, the prescribed dose was adjusted. The primary endpoint (UFC ≤ ULN or ≥50% decrease at Day 70) was achieved by all patients. Subsequently, in order to confirm these observations, protocol was amended (Protocol amendment 4) and new patients were enrolled and investigated for a longer treatment period. Following Protocol amendment 4, the study design was modified to include patients in Part II of the study for evaluating the long-term efficacy and safety of osilodrostat treatment for 22 weeks. Nineteen patients (15 who were treated in the expansion cohort in Part ll and 4 who participated in Part l) with Cushing's disease were enrolled as part of the Expansion cohort in Part II of the study. The 12 patients who had entered the study in Part I, were allowed to re-enter the study as the Core proof of concept (PoC) Follow-up cohort. At Day 70 ± 2 days (Week 10), all patients (both patients entering for the first time and those reentering the study) entered the 12-week assessment period. At Day 154, patients completed the End of Treatment-Core visit. On Day 154 (Week 22), patients had the option to enter the 12-month extension phase (long-term extension 1). On Day 490, patients who continued in the study had the option to enter a second long term extension phase (extension-2) at the Investigator's discretion, provided they did not meet any of the study discontinuation criteria.

Study Design


Intervention

Drug:
LCI699
Osilodrostat 1 mg and 5 mg capsules, was prepared by Novartis and supplied to the Investigator. The capsule formulation of osilodrostat was later changed to tablets and this change was implemented in the study with Protocol amendment 6. Osilodrostat was open labeled 1 mg, 5 mg, 10 mg and 20 mg tablets.

Primary Percentage of Responders to LCI699 Based on the Change in Mean Urinary Free Cortisol (UFC) From Baseline to Week 10 A patient was considered to be a responder if his/her mean UFC level from the three 24-hour urine samples collected at Week 10 was = Upper Limit of Normal (ULN), as defined by the local laboratories, or represented a =50% decrease from baseline. Patients who discontinued for a disease or treatment related reason (e.g. death, adverse event, clinical disease progression etc.), or whose mean Week 10 24-hour UFC levels were higher than the normal limit and experienced <50% decrease in UFC were classified as non-responders. 10 weeks

Secondary Actual Change From BL in Cardiovascular and Other Metabolic Parameters: Quantitative Insulin Sensitivity Check Index (QUICKI) Improving metabolic abnormalities was assessed by descriptive statistics on the change from baseline. QUICKI is the quantitative insulin sensitivity check index and is derived using the inverse of the sum of algorithms (base 10) of the fasting insulin and fasting glucose: 1/(log(fasting insulin mU/mL)+log(fasting glucose mg/dL)).
Values typically associated with the QUICKI calculation for insulin resistance in humans fall broadly within a range between 0.45 for unusually healthy individuals and 0.30 in diabetics. So lower numbers reflect greater insulin resistance.
