ACROSTUDY is a world-wide non-interventional, post marketing surveillance study performed to monitor the safety and outcomes of pegvisomant (PEG) in clinical practice. We report data from acromegaly patients who have been included in the Italian ACROSTUDY registry. The data of 341 acromegaly patients (171 males) were available for analysis using data freeze (12/9/2012). Patients were enrolled in 25 Italian endocrine centres. Before and during PEG treatment IGF-I, liver enzymes, metabolic parameters, and pituitary MRI were assessed. Before PEG, 54.3 % patients had been treated with medical therapy and surgery, 22.9 % medical therapy only, and 15.8 % medical plus radiation and surgical therapy. 199 adverse events were reported in 98 patients (28.7 %). Serious adverse events were documented in 29 patients (8.5 %). 71.1 % of patients had no significant change in tumor volume. Central MRI reading was performed in 34 patients; in 7 patients, an increase in tumor volume was found. Hormonal efficacy progressively increased since the start of PEG. After 6 years, normal IGF-I levels were found in 70.9 % of patients (mean daily dose 18.1 mg). 87.1 % of patients were treated with daily PEG although in 8.8 % of patients, it was administered 2-6 times per week and in 3.8 % with weekly injections. 74.8 % received a PEG dose 10-15 mg/daily. PEG is a drug with a favorable safety profile which is efficacious also considering that in Italy it is currently available as third-line therapy.

Abstract

ACROSTUDY is a world-wide non-interventional, post marketing surveillance study performed to monitor the safety and outcomes of pegvisomant (PEG) in clinical practice. We report data from acromegaly patients who have been included in the Italian ACROSTUDY registry. The data of 341 acromegaly patients (171 males) were available for analysis using data freeze (12/9/2012). Patients were enrolled in 25 Italian endocrine centres. Before and during PEG treatment IGF-I, liver enzymes, metabolic parameters, and pituitary MRI were assessed. Before PEG, 54.3 % patients had been treated with medical therapy and surgery, 22.9 % medical therapy only, and 15.8 % medical plus radiation and surgical therapy. 199 adverse events were reported in 98 patients (28.7 %). Serious adverse events were documented in 29 patients (8.5 %). 71.1 % of patients had no significant change in tumor volume. Central MRI reading was performed in 34 patients; in 7 patients, an increase in tumor volume was found. Hormonal efficacy progressively increased since the start of PEG. After 6 years, normal IGF-I levels were found in 70.9 % of patients (mean daily dose 18.1 mg). 87.1 % of patients were treated with daily PEG although in 8.8 % of patients, it was administered 2-6 times per week and in 3.8 % with weekly injections. 74.8 % received a PEG dose 10-15 mg/daily. PEG is a drug with a favorable safety profile which is efficacious also considering that in Italy it is currently available as third-line therapy.
