Efficacy and Safety of Pasireotide Long Acting Release (LAR) Versus Octreotide LAR or Lanreotide Autogel (ATG) in Patients With Inadequately Controlled Acromegaly

Percentage of Participants With a Reduction of Mean GH Levels to < 2.5 µg/L and Normalization of Sex- and Age-adjusted IGF-1.

Time frame · At 24 weeks

The primary objective of this study was to compare the percentage of patients achieving biochemical control (defined as mean GH levels \<2.5 µg/L and normalization of sex- and age- adjusted IGF-1) at 24 weeks with pasireotide LAR 40 mg and pasireotide LAR 60 mg separately versus continued treatment with octreotide LAR 30 mg or lanreotide autogel (ATG) 120 mg. The primary efficacy variable is the proportion of patients with a reduction of mean GH levels to \< 2.5 µg/L and normalization of sex- and age-adjusted IGF-1 at 24 weeks.

Percentage of Patients With Mean GH < 2.5 μg/L and Normalization of IGF-1, Treated With Pasireotide LAR Alone or With Concomitant Medications Used to Treat Acromegaly (Extension Full Analysis Set)

Time frame · Extension baseline up to approximately week 268

The percentage of patients achieving mean growth hormone (GH) levels \< 2.5 μg/L and normalization of sex and age-adjusted IGF-1 was calculated with two sided 95% confidence interval. All GH assessments were based on a 5-point mean growth hormone (GH) assessed from a 2-hour profile. Scheduled time points for blood sampling were pre-dose at 0, 30, 60, 90 and 120 minutes. Total insulin-like growth factor (IGF-1) levels were assessed with one pre-dose sample at the same visits as GH. Concomitant medication known to affect GH or IGF-1 levels were allowed in patients who were not biochemically controlled after at least one year treatment with pasireotide LAR monotherapy: dopamine agonists and growth hormone receptor antagonists (extension full analysis set)

n is the number of patients achieving response criteria. The weeks correspond to duration of first response (in weeks) for patients achieving biomedical control. Median and 95% CI are derived from Kaplan-Meier curves. Kaplan-Meier estimates \[95% CI\] at each time point are estimates of probability of response.
