- Scientific TitleRandomized double blind multi-centre study of the effects on low-dose pegvisomant treatment in acromegalic subjects in whom the IGF-I levels has been normalized by long-acting somatostatin analogs.
- hypothesis1. Addition of weekly pegvisomant administrations improves quality of life;
2. Addition of weekly pegvisomant administrations improves insulin sensitivity.
- Healt Condition(s) or Problem(s) studiedSomatostatin analogues , Acromegalia, Pituitary disease, Normal IGF1, Pegvisomant
- Inclusion criteria1. Provision of written informed consent prior to any study related procedures;
2. Male or female aged between 18 and 75 years inclusive;
3. The patient must have had documentation supporting the diagnosis of acromegaly based on elevated GH and/or IGF-1 levels;
4. The patient is treated with lanreotide Autogel or octreotide LAR for at least 6 months and has a serum IGF-1 level above the 60th percentile and below ULN, 28 days after the last injection.
- Exclusion criteria1. Has undergone pituitary surgery or radiotherapy within 6 months prior to study entry;
2. It is anticipated that the patient will receive pituitary surgery or radiotherapy during the study;
3. Has a history of hypersensitivity to lanreotide, octreotide or pegvisomant or drugs with a similar chemical structure;
4. Has already been treated with a somatostatin analogue associated with pegvisomant;
5. Has received a dopamine agonist within 6 weeks prior to study entry;
6. Has been treated with any unlicensed drug within the last 30 days before study entry;

Non-childbearing potential is defined as post-menopause for at least one year, surgical sterilization or hysterectomy at least three months before the start of the study;
9. Has a history of, or known current, problems with alcohol or drug abuse;
10. Has a mental condition rendering the subject unable to understand the nature, scope and possible consequences of the study, and/or evidence of an uncooperative attitude;
11. Has abnormal baseline findings, any other medical condition(s) or laboratory findings that, in the opinion of the investigator, might jeopardize the subjectís safety or decrease the chance of obtaining satisfactory data needed to achieve the objective(s) of the study;
12. Renal insufficiency, clearance < 60 ml/min;
13. Participation in a clinical trial in the last 6 months.

- Brief summaryRandomized double blind multi-centre study of the effects on low-dose pegvisomant treatment in acromegalic subjects in whom the IGF-I levels has been normalized by long-acting somatostatin analogs.

Primary Study Objective:
To assess the efficacy and safety of the co-administration of low-dose pegvisomant (40 mg, administered via subcutaneous injection given once a week) and long-acting somatostatin analogs (administered once monthly) on the Quality of Life over 16 weeks in 60 acromegalic patients.
The primary endpoint will be the change in the AcroQol-physical score at the end of the treatment period.

Secondary Study Objectives:
To assess the effect of low-dose pegvisomant co-administration on: Quality of life and insuline sensitivity.
1. AcroQoL and PASQ;
2. Oral glucose loading;
3. Total body water / body weight;
4. Blood pressure;
5. HbA1c;
6. BNP levels;
7. Ring-size;
8. IGF-I levels;
9. Safety based on:
A. Adverse events, clinical examination, vital signs;
B. Glucose tolerance;
C. Standard hematology and biochemistry, including liver function tests.
