F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

Subjects are excluded from the trial if any of the following criteria apply:
Lack of suitability for the trial:
1. Established diagnosis of a disease that is sufficient to explain growth deficiency or metabolic disorders that are also associated with short stature (e.g., Turner syndrome, skeletal dysplasia’s, celiac disease, etc.).
2. Ongoing growth hormone therapy.
3. Presence of hypothyroidism and/or adrenal insufficiency without adequate and stable replacement therapy treatment for at least 30 days prior to first GHST.
4. Treatment with drugs directly affecting the pituitary secretion of somatotropin (e.g., somatostatin analogues, clonidine, levodopa and dopamine agonists) or provoking the release of somatostatin (antimuscarinic agents e.g., atropine).
5. Medical history of ongoing clinically symptomatic psychiatric disorders.
6. 2nd or 3rd degree atrioventricular-block, prolongation of the QRS complex over 120 milliseconds, prolongation of the QTc interval over 450 milliseconds, or any other clinically significant abnormal electrocardiogram results at the screening ECG as judged by the investigator.
7. Previous participation in this trial. Participation is defined as signed informed consent.
8. Participation in any clinical trial of an approved or non-approved investigational medicinal product within 30 days before screening.
Safety concerns:
9. Known or suspected hypersensitivity to trial product(s) or related products;
10. Any disorder, which in the investigator’s opinion might jeopardize subject’s safety or compliance with the protocol.
11. Concomitant treatment with any drugs that might prolong QT/QTc
Note: A subject who receives such treatment will not be a candidate for this study, if his/her condition does not allow for a treatment-free period of at least 5 elimination half-lives of the drug that might prolong QT/QTc before the GHST;
12. Elevation of laboratory parameters indicating hepatic or renal dysfunction or damage (AST, ALT, GGT > 2.5 x ULN; creatinine or bilirubin > 1.5x ULN);
13. Current active malignancy other than non-melanoma skin cancer;
14. Female of child-bearing potential and not using an adequate contraceptive method (adequate contraceptive measures as required by local regulation or practice).
15. Male of reproductive age who or whose partner(s) is not using an adequate contraceptive method (adequate contraceptive measures as required by local regulation or practice).
Administrative reasons:
