Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Comparatore placebo: Placebo
Patients of Placebo Group will be treated with placebo sub-cutaneous in the same way as Somatropin during the double blind treatment phase. To maintain blind subject will be measured in the same way as the treatment group for IGF-I- Levels. Central lab will randomize placebo patients to dose change or maintenance of dose. This will ensure continued blinding of the study to patients and personnel.
Comparatore attivo: Vero
Fixed doses for patients: MALE: < 45y 0,4 mg, > 45y 0,2mg FEMALE: < 45y 0,5mg, >45y 0,3mg. for the first 4 weeks half of the dose will be given. After that dose will be increased to the targeted maintenance dose according to IGF-I Levels +/- 2 SD of age adjusted reference range. In case of side effects dosage will remain on half-dose (during the first 4 weeks) or reduced to half dose (after the first 4 weeks). At week 52 patients have the opportunity to switch to open label study restarting with half the given fixed dose which will be adjusted to full dose after 4 weeks.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change of Visceral Fat Mass Assessed by Magnetic Resonance Imaging Scanning (MRI)
Lasso di tempo: Baseline, 52 weeks
Fat measurements carried out with the subjects lying in a supine position in a MRI scanner. Measurements of regional body fat obtained between the level of the coccygeal bone and the 2nd or 3rd lumbar vertebra.
Baseline, 52 weeks

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Visceral Fat Mass in Subgroups
Lasso di tempo: Baseline, 52 weeks, 78 weeks
Change in visceral fat mass in subgroups. Subgroup 1: isolated GHD due to surgery and/or irradiation of pituitary adenoma and suprasellar tumors. Subgroup 2: history of traumatic brain injury (TBI) or subarachnoid hemorrhage (SAH).
Baseline, 52 weeks, 78 weeks
Change From Baseline in Anthropometric Parameters (Height)
Lasso di tempo: Baseline, 52 weeks, 78 weeks
Baseline, 52 weeks, 78 weeks
Change From Baseline in Anthropometric Parameters (Weight)
Lasso di tempo: Baseline, 52 weeks, 78 weeks
Baseline, 52 weeks, 78 weeks
Change From Baseline in Anthropometric Parameters (Waist Circumference)
Lasso di tempo: Baseline, 52 weeks, 78 weeks
Baseline, 52 weeks, 78 weeks
Change From Baseline in Alertness (Testbatterie Zur Aufmerksamkeitsprüfung [TAP]) and Memory (Auditory Verbal Learning Test [AVLT])
Lasso di tempo: Baseline, Week 52, Week 78
Alertness: software-based neuropsychological assessment for response time and errors. Memory: analysis of learning and retention using 5-trial presentation of 15-word list (A), single presentation of interference list (B), 2 postinterference recall trials - 1 immediate, 1 delayed - and recognition of the target words with distractors (C). Performance variables were immediate word span under overload conditions, final acquisition level, amount learned in 5 trials, interference, delayed recall, and recognition (implicit learning).
Baseline, Week 52, Week 78
Change From Baseline in Blood Pressure
Lasso di tempo: Baseline, Week 52, Week 78
Blood pressure was measured seated, the subject's arm supported at the level of the heart, and recorded to the nearest mm Hg. The same arm (preferably the dominant arm) was used throughout the trial. The subject was seated for 5 minutes before the blood pressure was obtained. Use of an automated device could have been used for measuring blood pressure.
Baseline, Week 52, Week 78
Change From Baseline in Heart Rate
Lasso di tempo: Baseline, Week 52, Week 78
The use of an automated device for measuring pulse rate was acceptable, although, when done manually, pulse rate was measured in the brachial/radial artery for at least 30 seconds.
Baseline, Week 52, Week 78
Change in Executive Function and Memory in Subgroups
Lasso di tempo: Baseline, Week 52, Week 78
Change in executive function and memory in subgroups. Subgroup 1: isolated Growth Hormone Deficiency (GHD)due to surgery and/or irradiation of pituitary adenoma and suprasellar tumors. Subgroup 2: history of traumatic brain injury (TBI) or subarachnoid hemorrhage (SAH). Median reaction time, the total number of errors, the number of omissions and the number of false positive reactions.
Baseline, Week 52, Week 78
Change From Baseline in Safety Laboratory Assessments
Lasso di tempo: Baseline, Week 52, Week 78
Prespecified safety laboratory assessments evaluated for change or no change from baseline. Possible responses were Yes/No.
Baseline, Week 52, Week 78
Change From Baseline in Homeostasis Model Assessment (HOMA)-Index
Lasso di tempo: Baseline, Week 52, Week 78
HOMA index is calculated by 1 of 2 methods: HOMA-Index = fasting insulin measured in microunits per milliliter (µU/ml) times fasting glucose measured in milligrams per deciliter mg/dl) divided by 405 or HOMA-Index = fasting insulin (µU/ml) times fasting glucose measured in millimoles per liter (mmol/l) divided by 22.5.
Baseline, Week 52, Week 78
Change From Baseline in Quality of Life Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA)
Lasso di tempo: Baseline, Week 52, Week 78
Participant self administered questionnaire consisting of 25 items that evoke yes or no answers. A score of 1 is given to each item affirmed and these are summed to give the total score. The maximum score is 25, which represents a poor quality of life. The minimum score is 0, which represents a good quality of life.
Baseline, Week 52, Week 78
Change From Baseline in Short Form (36) Health Survey (SF36)
Lasso di tempo: Baseline, Week 52, Week 78
Participant self administered questionnaire that measures each of the following eight health concepts: Physical Functioning (PF); Role-Physical (RP); Bodily Pain (BP); General Health (GH); Vitality (VT); Social Functioning (SF); Role-Emotional (RE); Mental Health (MH) as well as a reported Health Transition item (HT). Scale range 0 to 100, higher scores indicate a better health-related quality of life.
Baseline, Week 52, Week 78
Change From Baseline in European Quality of Life-5 Dimensions (EQ-5D)
Lasso di tempo: Baseline, Week 52, Week 78
Participant self-administered questionnaire EQ-5D, a 2 part generic health status instrument. The first part consists of 5 descriptors of current health state: mobility, self care, usual activities, pain/discomfort and anxiety/depression. Scores are assigned on a three-level scale (1= no problem, 2= some problem, 3= extreme problem). The second part was an overall rating of the participant's current health state using a 20 cm Visual Analogue Scale (EQ-VAS) with endpoints labelled 'best imaginable health state' and 'worst imaginable health state'.
Baseline, Week 52, Week 78
Change From Baseline in Cardiovascular Risk Factors
Lasso di tempo: Baseline, Week 52, Week 78
Change in values of laboratory tests indicative of possible cardiovascular risk factors: high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, N-terminal pro brain natriuretic peptide)
Baseline, Week 52, Week 78
