End point description |
Adverse event(AE)=any untoward medical occurrence in clinical investigation participant administered drug;it does not necessarily have to have causal relationship with this treatment. AE can therefore be any unfavorable&unintended sign (example,clinically significant abnormal laboratory value),symptom/disease temporally associated with use of drug whether/not it is considered related to drug. TEAE=any event emerging/manifesting at or after initiation of investigational product or any existing event that worsens in either intensity or frequency following exposure to investigational product. SAE=any untoward clinical manifestation of signs, symptoms/outcomes(whether considered related to investigational product or not)&at any dose: results in death,is life-threatening,requires in-patient hospitalization/prolongation of hospitalization,results in persistent/significant disability/incapacity,results in congenital abnormality/birth defect,or is an important medical event.

Percentage of Participants With TEAEs | ||||||||
End point description |
An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory value), symptom, or disease temporally associated with the use of a drug whether or not it is considered related to the drug. A TEAE is defined as any event emerging or manifesting at or after the initiation of the investigational product or any existing event that worsens in either intensity or frequency following exposure to the investigational product. The Safety Set (SAF) included all participants in the ITT Set who received at least 1 dose of VPRIV.

Percentage of Participants With Infusion-related Reactions Reported as an Adverse Event | ||||||||
End point description |
An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory value), symptom, or disease temporally associated with the use of a drug whether or not it is considered related to the drug. An infusion-related AE was defined as an AE that 1) began either during or within 12 hours after the start of the infusion and 2) was judged as possibly or probably related to the study treatment. The SAF included all participants in the ITT Set who received at least 1 dose of VPRIV.

Change From Baseline to Week 53 in 36-item Short Form General Health Survey (SF-36) Scores | ||||||||||||
End point description |
SF-36 Version 2 is a multipurpose, participant completed, short-form health survey with 36 questions that consists of an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures. Physical component summary (PCS) is mostly contributed by physical function (PF), role physical (RP), bodily pain (BP), and general health (GH). Mental component summary (MCS) is mostly contributed by mental health (MH), role emotional (RE), social function (SF), and vitality (VT). Each component on the SF-36 item health survey is scored from 0 (best) to 100 (worst). Total score ranges from 0-100 for each component summary (i.e., PCS and MCS), where higher scores are associated with less disability and better quality of life. The SAF included all participants in the ITT Set who received at least 1 dose of VPRIV. Subjects analysed is the number of participants with data available for analyses.

End point description |
The CHQ-PF-50 is a 50-item questionnaire to be completed by the parents or guardians of children between 5 and 18 years of age. The 50 questions measure 14 domains (global health, physical functioning, role/social limitations (emotional/behavioral and physical), bodily pain/discomfort, behavior, global behavior, mental health, self-esteem, general health perceptions, change in health, parental impact (emotional and time), family activities, and family cohesion) which were summarized as the physical and psychological summary scores. Each summary score was transformed and could range from 0 to 100, with higher score indicating better physical and psychosocial health. A positive change from Baseline indicates improved well-being. The SAF included all participants in the ITT Set who received at least 1 dose of VPRIV. Subjects analysed is the number of participants with data available for analyses.
