Conditions

Acromegaly is typically caused by a growth hormone (GH) secreting tumor in the pituitary. Excess GH secretion results in excess secretion of insulin-like growth factor-1 (IGF-1) from the liver, which causes bone overgrowth, organ enlargement, and changes in glucose and lipid metabolism. The symptoms of acromegaly include abnormal growth of hands and feet and changes in shape of the bones that result in alteration of facial features.

Design outcomes

Primary

MeasureTime frame
Main Objective: This study is designed ito evaluate the long-term safety and tolerability of CRN00808 in acromegaly subjects; to evaluate the efficacy of CRN00808 in acromegaly patients.;Secondary Objective: Not Applicable;Primary end point(s): Primary endpoint: The primary endpoint is the incidence of treatment-emergent AEs (TEAEs) throughout the study. ;Timepoint(s) of evaluation of this end point: study duration

Secondary

MeasureTime frame
Secondary end point(s): Secondary endpoints: -Change from W16 in IGF-1 levels; -Change from W16 in growth hormone (GH) levels Exploratory endpoints: -Proportion of subjects with the mean of their last 2 consecutive IGF-1 measurements =ULN at W52; -Proportion of subjects with the mean of their last 2 consecutive IGF-1 measurements =1.3×ULN at W52; -Proportion of subjects who achieve serum GH <5.0 ng/mL; -Proportion of subjects who achieve serum GH <2.5 ng/mL; -Number of consecutive visits with IGF-1 =ULN; -Number of consecutive visits with IGF-1 =1.3×ULN; -Change from baseline in serum Insulin-like growth factor binding protein-3 (IGFBP-3) levels; - Increase in serum GH, IGF-1, and IGFBP-3 levels after withdrawal of CRN00808; - Change from baseline in Acromegaly Quality of Life (AcroQoL) total score; - Change from baseline in acromegaly symptom diary (ASD total) score; - Subject treatment preference, as assessed by the Treatment Preference Questionnaire at W52; Other Safety Endpoints: - Clinical laboratory tests (hematology, serum chemistry, and urinalysis) at each post-baseline study visit; - Vital signs at each post-baseline study visit; - 12-lead ECG at each post-baseline study visit.;Timepoint(s) of evaluation of this end point: Specific time points are given in E.5.2
