End point description |
Insulin-like Growth Factor-1 SDS was calculated based on the actual value of IGF-1 minus reference value of IGF-1 divided by reference standard deviation of IGF-1. SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) a subject's value was relative to the mean of the reference population. The scores were centered around zero. Negative score indicated that the IGF-I value was lower compared to the reference population. The safety analysis set included all treated subjects who had received at least 1 administration of Saizen®. Here, "n" signifies those subjects who were evaluable for the specified category at each time point.

Number of Subjects With Treatment-emergent Adverse Events(TEAEs), Serious TEAEs, TEAEs Leading to Death, TEAEs Leading to Discontinuation | ||||||||||||||
End point description |
An adverse event (AE) was defined as any untoward medical occurrence in a subject which does not necessarily have a causal relationship with the study drug. An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAEs are those events with onset dates occurring during the on-treatment period or if the worsening of an event is during the on-treatment period. TEAEs include both Serious TEAEs and non-serious TEAEs. The safety analysis set.

Date |
Amendment |

31 Oct 2013 |
Modified exclusion criterion 3 to allow inclusion of subjects with adequately treated basal cell or squamous cell skin cancer. |
||
15 Jul 2014 |
1) Modified inclusion criterion 5 by increasing the maximum permitted BMI level measured at the Screening visit (Weight in kilograms / [Height in meters]^2 ) from less than or equal to (<=) 35 to <= 40 kg/m^ 2 .
2) Updated administrative information to reflect the change in the Sponsor’s medical responsible, clinical trial leader and the principal statistician. |
||
09 Oct 2014 |
1) Modified inclusion criterion 2 to allow recruitment of subjects with CO-AGHD as well as AO-AGHD.
2) Modified inclusion criterion 3 to allow enrollment of subjects who stopped prior GH treatment for AGHD 1 month prior to Screening as compared to at least 3 months prior to Screening previously.
3) Modified exclusion criterion 3 to ensure that the wording is in alignment with the Saizen label. Provided clarification that the presence of an active malignancy is a contraindication and that any pre-existing malignancy must be inactive with anti-tumor therapy completed prior to starting trial on Saizen therapy.
4) Updated administrative information to reflect the change in the Sponsor’s principal statistician and the central laboratory. |
