A Prospective Observational Study of Effect of Somatropin on Growth Hormone Deficient Adults

Study Overview
=================
Brief Summary
-----------------
The Hypopituitary Control and Complications Study HypoCCS is a prospective, open label, global, multicentre, observational study on routine clinical care of adults with growth hormone deficiency occurring either isolated or in combination with other pituitary hormone deficiencies. The objective of this observational study is to evaluate long-term safety and health outcomes for adult growth hormone deficient participants with or without somatropin replacement therapy. As an observational study, data are collected only as provided at the discretion of the attending physician. The participant enrolled meet the criteria of growth hormone deficiency in adults as per the Humatrope label in the country where their attending physician practices, and this diagnosis is at the discretion of the attending physician. The decision to receive somatropin or remain untreated is made by the participant in consultation with their attending physician. While treatment of adult growth hormone deficient participants with somatropin has been shown to be safe and effective in clinical trials of 18 months duration, this observational study aims to provide information on health outcome and replacement therapy over longer periods of time for a larger number of participants in the context of the overall disease environment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinically Significant Adverse Events | A summary of all reported serious adverse events (SAE) and other adverse events regardless of causality are provided in the Adverse Events module of this record. | Baseline to study completion (approximately 10 years) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cardiovascular Risk Factor-Change From Baseline in Body Mass Index (BMI) | Change in BMI was used as an indicator of cardiovascular risk. Body mass index (BMI) is an estimate of body fat based on body weight divided by height squared. | Baseline, interim time point (5 years), and study completion (10 years) | 
| Cardiovascular Risk Factor-Change From Baseline in Systolic (SBP) and Diastolic Blood Pressure (DBP) | Change in SBP and DBP were used as an indicator of cardiovascular risk. | Baseline, interim time point (5 years), and study completion (10 years) | 
| Cardiovascular Risk Factor-Change From Baseline in Cholesterol and Triglycerides | Change from baseline in total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides were used as an indicator of cardiovascular risk and are presented. | Baseline, interim time point (5 years), and study completion (10 years) | 
| Cardiovascular Risk Factor-Change From Baseline in Waist Circumference | Change in waist circumference was used as an indicator of cardiovascular risk. | Baseline, interim time point (5 years), and study completion (10 years) | 
| Percentage of Participants Experiencing a Bone Fracture (Fracture Incidence) |  | Baseline through 10 years | 
| Change From Baseline in the Total Z Score of the Disease-specific Module of the Questions of Life Satisfaction (QLS-H). | QLS-H is a self-administered, weighted, quality of life (QoL) questionnaire consisting of 9 items developed for participants with growth hormone deficiency. Scores were corrected for age, gender, and country differences, and expressed as Z-scores based on country-specific reference ranges. Participants indicate how important a certain dimension of QoL is to them and are then questioned as to their degree of satisfaction with that dimension. Each item is rated on a 5-point Likert scale ranging from not important (1) to extremely important (5) and from dissatisfied (1) to very satisfied (5). The weighted score for the degree of satisfaction (weighted satisfaction) with a particular dimension=(importance - 1)x(2 x satisfaction - 5). Total Z-score is obtained by adding the individual item scores of the 9 dimensions, and range from -108 (representing very low satisfaction) to +180 (representing very high satisfaction). | Baseline, interim time point (5 years), and study completion (10 years) |
