General information about the trial
|
|||
Main objective of the trial |
To evaluate the safety and tolerability of Fabrazyme in Chinese fabry disease subjects.
|
||
Protection of trial subjects |
The study was conducted by investigators experienced in the treatment of adults and paediatric subjects. The parent(s) or guardian(s) as well as the children were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time. In addition to the consent form for the parent(s)/guardian(s), an assent form in child-appropriate language was provided and explained to the child. Repeated invasive procedures were minimised. The number of blood samples as well as the amount of blood drawn were adjusted according to age and weight. A topical anesthesia may have been used to minimise distress and discomfort. Adult subjects were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time in language and terms appropriate for the subject and considering the local culture. During the course of the trial, subjects were provided with individual subject cards indicating the nature of the trial the subject is participating, contact details and any information needed in the event of a medical emergency. Collected personal data and human biological samples were processed in compliance with the Sanofi-Aventis Group Personal Data Protection Charter ensuring that the Group abides by the laws governing personal data protection in force in all countries in which it operates.

Number of Subjects with Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and Adverse Events of Special Interest (AESIs) [1] | ||||||||||||
End point description |
Adverse Event (AE) was defined as any untoward medical occurrence in subject who received study drug and did not necessarily had a causal relationship with treatment. TEAEs were defined as AEs that developed, worsened/became serious during treatment-emergent period (time from 1st dose of study drug to the last dose of study drug + 14 days). SAE was any AE that at any dose: resulted in death, was life-threatening, required inpatient hospitalisation or prolongation of existing hospitalisation, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was medically important event or was suspected transmission of any infectious agent via authorised medicinal product. AESI was any AE of scientific and medical concern specific to the study for which ongoing monitoring and immediate notification to the Sponsor was required. Analysis performed on exposed population which included all enrolled subjects who had taken at least one dose of study drug.

Number of Subjects with Infusion Associated Reactions (IARs) [2] | ||||||
End point description |
Adverse Event was defined as any untoward medical occurrence in subject who received study drug and did not necessarily had a causal relationship with treatment. Infusion Associated Reactions (IARs) were the AEs that occurred during the infusion or within 24 hours after the start of infusion and was considered as related or possibly related to the study intervention by the Investigator or the Sponsor. An event occurring >=24 hours after the start of an infusion may be deemed an IAR if a delayed reaction was considered possible by the Investigator or the Sponsor. Analysis was performed on exposed population.
