Canadian Continuation of Roll-over Study in Patients With Endogenous Cushing's Syndrome

Continuation of an Open-label, Multi-center Study to Assess Long Term Safety in Canadian Patients With Endogenous Cushing's Syndrome Who Have Completed Prior Recordati-sponsored Osilodrostat (LCI699) Study LCI699C2X01B and Are Judged by the Investigator to Benefit From Continued Treatment With Osilodrostat

The purpose of this study is to continue the evaluation of long-term safety of osilodrostat in 7 Canadian patients who have already received osilodrostat treatment in a previous Global Recordati-sponsored roll-over study and who, based on investigators' judgement, will continue benefiting with its administration.

There will be no screening period for this study. Eligible subjects can start their treatment with osilodrostat as soon as they are enrolled in the study. The first study visit will be scheduled at the time of the last study visit for the parent study. Subjects must return to the study center at least on a quarterly basis (every 12 weeks ± 2 weeks) for safety and clinical benefit assessments, and resupply of study medication. Drug dispensing and administration information and adverse events will be collected. The subject may return to the clinic at any given time as per standard of care or treating physician recommendation; however, only the quarterly study visits will be recorded in the Case Report Form (CRF). Study medication dispensed will be recorded in the CRF dose administration page.

All adverse events and serious adverse events, including pregnancy, will be collected throughout the study. Subjects will continue to be treated in this roll-over study until they are no longer benefiting from their osilodrostat treatment as judged by the Investigator or until osilodrostat is commercially available or until one of other discontinuation criteria is met.

Inclusion Criteria:

1. Patient is currently participating in a Global Recordati-sponsored roll-over study receiving osilodrostat for any type of endogenous CS and has fulfilled all their requirements in the parent study.

3. Patient has demonstrated compliance, as assessed by the Investigator, with the parent roll-over study protocol requirements.
