Pasireotide trough levels (Ctrough) was 1 of the parameters used for PK assessments. Ctrough is the pre-dose PK concentration with an elapsed time from previous injection of 28+/-2 days. All patients randomized to the study had at least 1 PK observation & were therefore included in the pharmacokinetic analysis set. PK observations with missing concentrations, missing dose, missing elapsed time or an elapsed time from previous injection outside of 28 ±2 days window were excluded. Given that SOM230 LAR was administered once a month, Ctrough was collected every 28 days and thus this provides a summary of Ctrough values provided by incident dose (last dose administered prior to PK sample collection), not by randomized dose, hence each column is equivalent to an incident dose & not an arm/group. Patients randomized to either 10mg or 30mg could be titrated down to 5mg due to safety, or titrated up to 40mg, hence the 4 incident doses/columns that were allowed per protocol during this study.

Pharmacokinetic analysis set (PAS): The PAS consists of all randomized patients who have received at least one dose of study drug and had at least one post dosing PK assessment.

Patients were analyzed according to incident dose (defined as the last dose prior to the PK sample).

Pasireotide peak levels (Cmax) was one of the parameters used for PK assessments. Cmax is the post-dose PK concentration with an elapsed time from the previous injection of 21+/-2 days. All patients randomized to the study had at least one PK observation and were therefore included in the pharmacokinetic analysis set (PAS). Cmax PK observations ("Day 20" and "Day 104") with an elapsed time from the previous injection outside of 21+/-2 days window were excluded. Given that SOM230 LAR was administered once a month, the Cmax were collected every 28 days in this study, thus this provides a summary of Cmax values provided by incident dose (last dose administered prior to PK sample collection), not by randomized dose, hence each column is equivalent to an incident dose and not an arm/group. Patients randomized to either the 10mg or 30mg could be titrated down to 5mg due to safety, or titrated up to 40mg, hence the 4 incident doses/columns that were allowed per protocol during this study.

CushingQol is a disease-specific patient-reported outcome instrument. It is a single-domain 12 item Cushing's disease quality of life instrument. The Cushing's syndrome quality of life (CushingQoL) questionnaire is a single domain questionnaire which includes 12 self-report items scored using a five point Likert scale anchored at (1=always/very much and 5=never/not at all). The patient is asked to report what they think or feel about their Cushing's syndrome and how much the illness has interfered in usual activities over the past 4 weeks. The total score is standardized on a 0-100 scale with lower scores indicating a greater impact on quality of life.

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.
