Filter by:Evaluate biochemical differences in acromegalic patients treated with surgery versus somatostatin analogues (SMS) (after surgery or alone). Hypothesis: Treatment modality exhibit different biochemical responses in acromegaly.
To test the hypothesis that both lack and excess of growth hormone (GH) is associated with cardiac abnormalities. Cardiac function and morphology will be evaluated by MRI before and after treatment.
Hypothesis: Fractionated stereotactic radiotherapy is a safe therapy for treatment of patients with acromegaly in terms of both tumour control and biochemical remission
Growth hormone (GH) and Insulin-like growth factor-I (IGF-I) secretion are altered in acromegaly and type 2 Diabetes Mellitis (DM). The secretion of GH is mediated by central hypothalamic hormones (GH Releasing Hormone and somatostatin) as well as peripheral factors providing feedback inhibition (IGF-I and glucose, among others). The purpose of this study is to compare growth hormone suppression after an oral glucose tolerance test (OGTT) to growth hormone suppression after recombinant human IGF-I (rhIGF-I) administration. This study will recruit participants with active acromegaly, type 2 diabetes mellitus, and healthy control subjects. Each participant will undergo a screening evaluation, and three subsequent visits. Each participant will receive a placebo subcutaneous injection, OGTT, and administration of rhIGF-I, on separate visit days. Glucose, insulin, GH, bioactive IGF-I and IGF-I binding proteins will be measured after each intervention. Results will be compared between the three groups. It is predicted that the administration of rhIGF-I will demonstrate GH suppression in all healthy subjects and subjects with type 2DM. Some acromegaly subjects may demonstrate GH suppression in response to IGF-I administration, but not to the degree seen in healthy subjects or type 2 DM. OGTT will demonstrate suppression of GH in normal subjects, and will show attenuated suppression in type 2 DM and a failure of suppression in acromegaly.
To evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) response of a hydrated and non-hydrated 84 mg octreotide implant in patients with acromegaly in the first 6 weeks of treatment.
This open-label, national, prospective, observational, non-interventional, multi-center, post marketing surveillance study was performed in order to examine the efficacy and safety of Somavert® in treatment of subjects with acromegaly and its effects on acromegaly related co-morbidities.
The purpose of this study, is to assess the safety and local tolerability of the long-term use of Somatuline Autogel when administered by patients or their partners ("Home Injection Group") and the safety and local tolerability in patients receiving their injection from a healthcare professional (HCP) ("Reference Group").
To investigate the 60 month impact of surgery and somatostatin analogues (SSA) on glucose metabolism in acromegaly we will analyzed data from 100 patients with acromegaly according with different treatments (group A=with SSA only; group B= SSA followed by surgery; group C= surgery only; group D= surgery followed by SSA). At diagnosis and after 6-12 and 60 months were analyzed as primary outcome measure changes in fasting glucose and as secondary outcome measures changes of glycated hemoglobin (HbA1c) and insulin levels, HOMA-R and HOMA-β, representing insulin resistance and β-cell function, respectively. We will enrol 100 patients and expect half of them to have IGT or diabetes mellitus. We do not expect changes according with different treatment after 60 months while SSA-treated patients might experience deterioration of glucose tolerance after 6-12 months. We intend to look for predictors of deterioration of glucose tolerance.
The purpose of the study is to assess the efficacy of an extended injection interval schedule of lanreotide Autogel 120 mg in acromegalic subjects who are biochemically controlled on long term treatment with octreotide LAR 10 or 20 mg
Acromegaly is a chronic disease caused by excessive secretion of growth hormone (GH) and mainly due to benign tumour localized in the pituitary gland. The disease develops insidiously, causing a gradual progression of symptoms; consequently most patients are diagnosed in their fourth decade of life. Administration of somatostatin analogues such as lanreotide have been shown to result in normalisation or the decrease of GH and insulin growth factor (IGF-1) levels and improvement of clinical symptoms in acromegalic patients. The purpose of this study is to evaluate whether lanreotide is also effective on tumour volume reduction (tumour shrinkage) and the benefits of this potential tumour shrinkage on disease symptoms and patient's quality of life.
