Safety and Efficacy of Pasireotide Long Acting Release (LAR) vs. Octreotide LAR in Patients With Active Acromegaly

Percentage of Participants With a Reduction of Mean GH Level to <2.5 μg/L and the Normalization of IGF-1

Time frame · 12 months

Percentage of participants with a reduction of mean GH levels to \<2.5μg/L (based on a 5-point 2-hour profile) and normalization of sex- and age-adjusted IGF-1. Post surgery = patients with prior surgery but no previous medical treatment for acromegaly De novo = patients with de novo disease who refused pituitary surgery or for whom pituitary surgery was contraindicated.

Percentage of Participants With a Reduction of Mean GH Level to < 2.5μg/L

Time frame · 12 Months

Percentage of participants with a reduction of mean GH levels to \< 2.5μg/L (based on a 5-point 2-hour profile). Post surgery = patients with prior surgery but no previous medical treatment for acromegaly De novo = patients with de novo disease who refused pituitary surgery or for whom pituitary surgery was contraindicated.

Change From Baseline in Tumor Volume at 12 Months

Time frame · Baseline, 12 Months

Absolute and percentage change from baseline in tumor volume (assessed by pituitary MRI) Post surgery = patients with prior surgery but no previous medical treatment for acromegaly De novo = patients with de novo disease who refused pituitary surgery or for whom pituitary surgery was contraindicated.

Percentage of Participants With Normalization of IGF-1

Time frame · 12 Months

Percentage of participants with normalization of sex- and age-adjusted IGF-1. Post surgery = patients with prior surgery but no previous medical treatment for acromegaly De novo = patients with de novo disease who refused pituitary surgery or for whom pituitary surgery was contraindicated.

Percentage of Participants With a Reduction of Mean GH Level to < 2.5μg/L and Normalization of IGF-1

Time frame · Months 3, 6, 9, 12, 16, 19, 22, 25

Percentage of participants with a reduction of mean GH levels to \< 2.5μg/L (based on a 5-point 2-hour profile) and normalization of sex- and age-adjusted IGF-1. 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.)

Summary of Mean GH Values

Time frame · Baseline, Months 3, 6, 9, 12, 16, 19, 22, 25

Mean GH levels (based on a 5-point profile over 2 hours). 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).

Time to First Response for Patients Achieving a Reduction of Mean GH Level to < 2.5 μg/L and Normalization of IGF-1 (No. of Responders: Pasireotite LAR = 81, Octreotide LAR = 63) )

Time frame · Up to 26 months

Time to first response for patients achieving a reduction of mean GH level to \< 2.5 μg/L and normalization of IGF-1. 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).

Severity Scores of Acromegaly Symptoms

Time frame · Baseline, Months 12, 25

Severity scores of acromegaly symptoms (Headache, Fatigue, Perspiration, Paresthesias, Osteoarthralgia). Symptoms were scored from 0 (no symptom) to 4 (very severe). 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).

Ring Size

Time frame · Baseline, Months 12, 25

Ring size (based on jeweler's finger gauge). 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).

Health-related Quality-of-life as Measured by the AcroQoL Questionnaire

Time frame · Baseline, Months 12, 25

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).

Summary of Prolactin Levels

Time frame · Baseline, Months 12, 25

Prolactin Levels. 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).
