Screening details |
A total of 42 subjects were enrolled and treated in this study. Based on one year safety follow-up, subjects will be followed to Epoch 3 if anti-rHuPH20 antibody titer >= 160, and who experience either a related SAE or a related severe AE during Epoch 1 or Epoch 2. Data was reported based on interim analysis cut-off date (14-May-2020). | |||||||||||||||||||||

Arm description |
Pediatric subjects with PIDD who were on non-HyQvia intravenous (IV) or subcutaneous (SC) treatment with immunoglobulin (IV-pretreated, SC-pretreated) were enrolled and treated with HyQvia (Immune Globulin Infusion 10% [Human] with Recombinant Human Hyaluronidase) SC with a dose or interval ramp-up period of up to 6 weeks. HyQvia was administered at a starting dose of 5 milliliter per hour per site (mL/h/site) to maximum tolerated dose of 80 mL/h/site (for subject with body weight [BW] < 40 kilogram [kg]) or starting dose of 10 mL/h/site to maximum tolerated dose of 240 mL/h/site (for subject with BW greater than or equal to [>=] 40 kg). | |||||||||||||||||||||

Arm description |
Pediatric subjects who were treated with HyQvia prior to this study and those who completed the ramp-up period (Epoch 1) are followed by Epoch 2 with HyQvia treatment. After one year in Epoch 2, subjects with anti-rHuPH20 antibody titer <160 at all time-points during the study will complete the study termination/completion visit at the next possible occasion. Subjects with anti-rHuPH20 antibody titer >= 160 during the study and/or at the last measurement will continue for an additional two years of HyQvia treatment and observation. HyQvia was administered at a starting dose of 10 mL/h/site to maximum tolerated dose of 160 mL/h/site (for subject with body weight [BW] <40kg) or starting dose of 10 mL/h/site to maximum tolerated dose of 300 mL/h/site (for subject with BW >=40kg). | |||||||||||||||||||||

An Adverse Events (AEs) was defined as any untoward medical occurrence in a subject administered an investigational product (IP) that does not necessarily have a causal relationship with the treatment. TEAE was defined as AEs with onset after date-time of first dose of IP, or medical conditions present prior to the start of IP but increased in severity or relationship after date-time of first dose of IP. Related AEs was defined as an AE that was recorded as “possibly related” or “probably related” to IP was considered “related AE”, and AE recorded as “unlikely related” or “not related” was considered “unrelated” AE. Safety analysis set included all subjects in the full analysis set (enrolled set) who received at least one dose of HyQvia.

Health Related Quality of Life (HR QoL): Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) | ||||||||||||
End point description |
TSQM-9 was a 9-item, validated, self-administered instrument to assess subjects satisfaction with medication. The 3 domains assessed are effectiveness, convenience, and global satisfaction. The score of each of the 3 domains is based on an algorithm to create a score of 0 to 100. Higher score indicated greater satisfaction in that domain.

HRQoL: Pediatric Quality of Life Questionnaire (PedsQL) | ||||||||||||
End point description |
The Peds-QL was a generic HR QoL instrument designed specifically for a pediatric population. It captures the following domains: general health/activities, feelings/emotional, social functioning, school functioning. For this study, the Peds-QL for 8 to 18-year-old subjects was used. Higher scores indicate better quality of life (QOL) for all domains of the Peds-QL. This modular instrument uses a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored.

End point description |
EQ-5D considered five attributes of quality of life evaluation, that is, mobility, self-care, usual activity, pain/discomfort, and anxiety/depression. Each dimension had five possible levels: 1 (no problems); 2 (slight problems); 3 (moderate problems); 4 (severe problems), and; 5 (extreme problems). EQ-5D also included an additional visual analogic scale (EQ-VAS), which ranged from 0 to 100, where 0 indicated worst imaginable health state and 100 was best imaginable health state.

Reporting group description |
Pediatric subjects with PIDD who were on non-HyQvia intravenous (IV) or subcutaneous (SC) treatment with immunoglobulin (IV-pretreated, SC-pretreated) were enrolled and treated with HyQvia (Immune Globulin Infusion 10% [Human] with Recombinant Human Hyaluronidase) SC with a dose or interval ramp-up period of up to 6 weeks. HyQvia was administered at a starting dose of 5 milliliter per hour per site (mL/h/site) to maximum tolerated dose of 80 mL/h/site (for subject with body weight [BW] < 40 kilogram [kg]) or starting dose of 10 mL/h/site to maximum tolerated dose of 240 mL/h/site (for subject with BW greater than or equal to [>=] 40 kg). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Reporting group description |
Pediatric subjects who were treated with HyQvia prior to this study and those who completed the ramp-up period (Epoch 1) are followed by Epoch 2 with HyQvia treatment. After one year in Epoch 2, subjects with anti-rHuPH20 antibody titer <160 at all time-points during the study will complete the study termination/completion visit at the next possible occasion. Subjects with anti-rHuPH20 antibody titer >= 160 during the study and/or at the last measurement will continue for an additional two years of HyQvia treatment and observation. HyQvia was administered at a starting dose of 10 mL/h/site to maximum tolerated dose of 160 mL/h/site (for subject with body weight [BW] <40kg) or starting dose of 10 mL/h/site to maximum tolerated dose of 300 mL/h/site (for subject with BW >=40kg). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
