Therapeutic Strategies in Acromegalic Subjects Treated With Lanreotide 120mg

Study Overview
=================
Brief Summary
-----------------
The study aims to evaluate the biochemical and clinical effectiveness on symptoms and tumor size of a monotherapy with Lanreotide 120mg in acromegalic subjects, to describe criteria for starting alternative strategies, and to describe the modalities and the global effectiveness of alternative strategies.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of subjects who achieve a safe concentration of random Growth Hormone (GH) (≤2.5 ng/mL) and normal age and sex-matched Insulin-like Growth Factor-1 (IGF-1) concentration of the monotherapy phase. |  | Month 5 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

| History of acromegaly | Description of the date of diagnosis, GH and IGF-1 levels and tumor volume at diagnosis | Baseline | 
| History of treatment | Description between the diagnosis of acromegaly and the 1st injection of Lanreotide 120mg (treatments, doses) | Baseline | 
| Achievement of safe concentration of random GH (≤2.5 ng/mL) and normal age- and sex-matched IGF-1 concentrations of the monotherapy phase |  | Month 12 and 18 | 
| Raw values at each visit and change from baseline in random Growth Hormone (GH) |  | Baseline, month 5, 12 and 18 | 
| Raw values at each visit and change from baseline in overall health status (Patient-Assessed Acromegaly Symptom Questionnaire - PASQ) of the monotherapy phase |  | Baseline, month 5, 12 and 18 | 
| Raw values at each visit and change from baseline in the Acromegaly Quality of Life Questionnaire (ACROQoL total score and each dimension) of the monotherapy phase |  | Baseline, month 5, 12 and 18 | 
| Description of the GH and Insulin-like Growth Factor-1 (IGF-1) levels when the physician decides to start the first alternative strategy | Assessed in the alternate strategy phase | Day 1 (Visit 5) | 
| Proportion of subjects achieving biochemical control (random GH ≤2.5 ng/mL and normal age- and sex-matched IGF-1 concentrations) at month 18 time point of the alternative strategy phase (18 months after the start of the first alternative strategy) |  | Month 18 | 
| Number of alternative strategies used during the alternative strategy phase |  | Month 18 | 
| Treatments received at least once during the alternative strategy phase |  | Month 18 |

| Change in clinical score (PASQ) between baseline (month 0) of the monotherapy phase and month 18 time point of the alternative strategy phase |  | Month 18 | 
| Change in overall health status (PASQ) between baseline (month 0) of the monotherapy phase and month 18 time point of the alternative phase |  | Month 18 | 
| Change in Acromegaly Quality of Life Questionnaire (ACROQoL total score and dimensions) between baseline (month 0) of the monotherapy phase and Month 18 time point of the alternative strategy phase |  | Month 18 |
