Intervención / Tratamiento |
|---|---|
|
Comparador de placebos: 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.
|
|
Comparador activo: Verum
|
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.

Change From Baseline in Alertness (Testbatterie Zur Aufmerksamkeitsprüfung [TAP]) and Memory (Auditory Verbal Learning Test [AVLT])
Periodo de tiempo: 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).

|
Change From Baseline in Blood Pressure
Periodo de tiempo: 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.

Change From Baseline in Quality of Life Assessment of Growth Hormone Deficiency in Adults (QoL-AGHDA)
Periodo de tiempo: 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.

Change From Baseline in Short Form (36) Health Survey (SF36)
Periodo de tiempo: 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.

Change From Baseline in European Quality of Life-5 Dimensions (EQ-5D)
Periodo de tiempo: 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'.
