Denominator for time points up to Month 12 is the Full Analysis Set (FAS). Denominator for time points after Month 12 excludes patients who completed the core and did not enter the extension. Patients who discontinued were considered non-responders for the time points after discontinuation, patients who crossed over were considered non-responders for all time points after crossover. Analysis was based on data up to crossover (i.e., included data from both blinded core & ext. phase up to 26 Months for patients who continued the same treatment in the extension. For patients who switched to the other treatment, only data collected before crossover was included.)

Health-related Quality-of-life as Measured by the AcroQoL Questionnaire
Acromegalyy quality of life (AcroQoL) total scores. The AcroQoL questionnaire is unidimensional and contains 22 items divided in two scales: one that evaluates physical aspects (eight items) and another one that evaluates psychological aspects (14 items). The scoring of the questionnaire was performed as specified by the instrument developers. Total scores range from 0 to 100. Higher scores represent better quality of life. Analysis was based on data up to crossover (i.e., included data from both blinded core and extension phase up to 26 Months for patients who continued the same treatment in the extension. For patients who switched to the other treatment, only data collected before crossover was included).

Duration of Response for Patients Achieving a Reduction of Mean GH Level to <2.5 μg/L and the Normalization of IGF-1 at Month 12 (No. of Responders: Pasireotide LAR = 51, Octreotide LAR = 32)
The duration of response is defined as the time from the date that patient first met and maintained the response criteria based on primary efficacy variable to the date that patient lost response status.
Median and corresponding 95% CI are derived based on Kaplan-Meier method. Analysis was based on data up to crossover (i.e., included data from both blinded core and extension phase up to 26 Months for patients who continued the same treatment in the extension. For patients who switched to the other treatment, only data collected before crossover was included).
