Pediatric Quality of Life Inventory (Pedsql) Score
The PedsQL™ Measurement Model is a modular approach to measuring health-related QoL in healthy children and adolescents and those with acute and chronic health conditions. The 23-item PedsQL™ Generic Core Scales were designed to measure the core dimension of health as delineated by the World Health Organization, as well as role (school) functioning.
The total scale score (23 items) consists of Physical health summary score (8 items) and Psychosocial health summary score (15 items). Physical health summary includes Physical Functioning (8 items) and Psychosocial health summary score includes Emotional Functioning (5 items), Social Functioning (5 items) and School Functioning (5 items). The overall range for PedsQL scores is 0 to 100, with a higher score indicating better quality of life.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Kedrion IVIG 10% in people with Primary Immunodeficiency Disease, run by Kedrion S.p.A. at 21 sites in 6 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 18 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 21 sites in United States, Italy, Portugal, Russia, Hungary and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence Rate of Acute Serious Bacterial Infections (time frame: From Baseline (Day 1) up to week 51/52). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2026.
