Population Inadequately Controlled on other Somatostatin Analog
A multicenter, randomized, 3-arm trial was conducted in subjects with acromegaly inadequately controlled on somatostatin analogs. Subjects were randomized to double-blind Signifor LAR 40 mg (n=65) or Signifor LAR 60 mg (n=65) or to continued open-label pre-trial somatostatin analog therapies at maximal or near
maximal doses (n=68). A total of 181 subjects completed the 6 month trial. The efficacy endpoint was the proportion of subjects with a mean GH level less than 2.5 mcg/L and normal IGF-1 levels at week 24. The primary analysis compared Signifor LAR 60 mg and 40 mg to continued pretrial therapy (i.e., no change in treatment). The proportion of subjects achieving biochemical control was 15.4% and 20.0% for Signifor LAR 40 mg and 60 mg, respectively, at 6 months. Biochemical control was achieved by Month 3 in 15.4% and 18.5% of subjects in the Signifor LAR 40 mg and 60 mg arms, respectively.
