Lanreotide Autogel-120 mg as First-Line Treatment of Acromegaly - Full Text View

Purpose

Recently, a new formulation of lanreotide, lanreotide Autogel (ATG) 60 mg, 90 mg and 120 mg was developed in order to further extend the duration of the release of the active ingredient. The ATG formulation consists of a solution of lanreotide in water with no additional excipients. ATG was found to have linear pharmacokinetics for the 60 to 120 mg doses and provided a prolonged dosing interval and good tolerability (1). In some previous studies, the ATG was demonstrated as effective as the micro-particle lanreotide (2,3) and as octreotide-LAR in patients with acromegaly (4-7).

Data on the efficacy of ATG in newly diagnosed patients with acromegaly are still lacking. Similarly, the prevalence and amount of tumor shrinkage after ATG treatment is unknown. This information is particularly useful in the setting of first-line therapy of acromegaly that is currently becoming a more frequent approach to the disease (8). It is demonstrated that approximately 80% of the patients treated with depot somatostatin analogues as first line have a greater than 20% tumor shrinkage during the first 12 months of treatment (9). A definition of significant tumor shrinkage was provided in 14 studies (including a total number of patients of 424) and the results showed that 36.6% (weighted mean percentage) of patients receiving first-line somatostatin analogues therapy for acromegaly had a significant reduction in tumor size (10). About 50% of the patients were found to have a greater than 50% tumor shrinkage within the first year of treatment (10); in this study we found that percent decrease in IGF-I levels was the major determinant of tumor shrinkage (10).

The current open, prospective study is designed to investigate the prevalence and amount of tumor shrinkage in newly diagnosed patients with acromegaly treated first-line with ATG.

Arms	Assigned Interventions
Experimental: A Newly diagnosed patients with acromegaly	Drug: Lanreotide-Autogel 120 mg ATG120 mg is given as deep subcutaneous injection into the buttock. Each patient receives one deep subcutaneous injection of ATG120 mg at Visit 1 (V1) and subsequent injection every 4 weeks for 3 injections. Based on GH levels, the dosing interval has been determined as follows: if GH levels were > 2.5 mcg/l, ATG 120 mg is given every 4 weeks while if they were < 2.5 mcg/l ATG 120 mg is administered every 6 weeks for another 3 injections. Afterwards, the dose is maintained as above except in patients with GH levels <1 mcg/l receiving ATG 120 mg every 8 weeks.

Detailed Description:

This is an open, prospective, observational, clinical study to be performed in two University Hospitals (Naples and Genova, Italy). The primary objective is to evaluate the efficacy of the ATG 120 mg on control of GH and IGF-I excess in acromegaly according with the currently accepted criteria (12) and on tumor shrinkage. The secondary objectives are to assess improvement of clinical symptoms and safety profile. The study population will consist of at least 20 patients, enrolled in the two centers from Jan 1st 2003 to June 30th 2007. Patients give their written informed consent prior to entering into the study. The study was performed according to the principles defined by the declaration The safety population, as defined by the protocol, consists of patients who received at least one study drug dosing.

Hormonal evaluation GH levels are assessed as a mean value of 5 samples at 30-min intervals (starting between 08:00 and 9:00 in the morning) taken at each visit before the injection of ATG. IGF-I levels are assessed as a single sample taken at each visit at the same time as the first GH sample. All hormonal parameters were assessed in a central laboratory (University of Genoa).

Improvement in clinical symptoms is considered on the basis of a semiquantitative scale for asthenia, hyperhidrosis, headache, swelling of extremities, arthralgia, paraesthesia, carpal tunnel syndrome: symptoms were graded as 0 = absent, 1 = mild, 2 = moderate, 3 = severe.

Any adverse event (AE) during the study is monitored and reported by the investigators. Safety, evaluated by local laboratory data, is assessed at inclusion and at the final visit by: hematology: erythrocytes, leukocytes, platelets, haemoglobin, hematocrit; biochemistry: glucose, creatinine, alkaline phosphatase, total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), electrolytes (sodium, potassium, calcium, phosphorous) glycosylated haemoglobin, triglycerides, total and high density lipoproteins (HDL) cholesterol, blood amylase, iron, transferrin, prothrombin; glucose and insulin concentrations; hormonal evaluation: thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free triiodothyronine (FT4), follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels. Safety related to gallbladder is assessed by ultrasound examination performed at inclusion and at the end of the study.
