Lanreotide Autogel and Pegvisomant Combination Therapy in Acromegalic Patients

• Status: Completed
• Trial end date: 2008-10-01
• Target enrollment: 0
• Participant gender: All

Summary

The main aim of this study is to assess the efficacy of the co-administration of lanreotide Autogel 120 mg (administered via deep sub-cutaneous injections every 28 days) and pegvisomant (administered at 40 to 120 mg per week via sub-cutaneous injection given once or twice a week) on IGF-1 levels over 28 weeks in acromegalic patients. The primary endpoint will be the percentage of acromegalic patients with normalised (age and sex adjusted) IGF-1 level at the end of the co-treatment period.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

• The patient must have had documentation supporting the diagnosis of acromegaly, including elevated GH and/or IGF-1 levels

• The patient is treated with pegvisomant, because of IGF-1 level remaining above ULN when treated with somatostatin analogue, on a daily basis for at least 3 months and has normal (age and sex adjusted) IGF-1 level, or IGF-1 level above the upper limit of normal (ULN) after treatment with pegvisomant 30 mg per day, OR the patient is treated with lanreotide Autogel or octreotide LAR for at least 6 months including 3 months at the highest marketed dose and has a serum IGF-1 level above ULN, 28 days after the last injection

• At the end of the run-in period, The patient has a serum IGF-1 level above 1.2 x ULN, or a serum IGF-1 level between ULN and 1.2 x ULN and a serum GH nadir > 1 µg/L (assessed by an OGTT), 28 days after the 3rd injection of lanreotide Autogel 120 mg OR the patient is diabetic and has a serum IGF-1 level above 1.2 ULN, 28 days after the 3rd injection of lanreotide Autogel 120 mg

Exclusion Criteria:

• The patient has undergone pituitary surgery or radiotherapy within 6 months prior to study entry, or it is anticipated that it will be done during the study

• The patient has already been treated with a somatostatin analogue associated with a GH antagonist

• The patient has received dopamine agonist within 6 weeks prior to the study entry

• The patient has abnormal hepatic function at study entry (defined as AST, ALT, GGT, alkaline phosphatase, prothrombin time or total bilirubin above 2 ULN)

• The patient is at risk of pregnancy or is lactating
