Change From Baseline to Week 25 in Primary Immune Thrombocytopenia Patient Assessment Questionnaire (ITP-PAQ) Symptoms Score
The ITP-PAQ Version 1 is a 44 item disease-specific Health-Related Quality of Life questionnaire developed for use in adults with chronic ITP. It includes 10 scales, Four of the scales measure physical health: Symptoms (6 items), Bother (3 items), Fatigue (4 items), and Activity (2 items). Two of the scales measure emotional health: Fear (5 items) and Psychological (5 items) Health. The remaining four scales measure other aspects of quality of life (QOL): Work QOL (4 items), Social QOL (4 items), Women's Reproductive QOL (6 items) and Overall QOL (5 items). Each item is rated on a Likert-type scale containing 4 to 7 responses. All item scores are transformed to a 0 to 100 continuum and are weighted equally to derive individual scale scores and the total score (0-100) is calculated as per the formula: Sum of item scores within the scale/raw sum range\*100. Higher scores indicate better health status.
Time frame: From Baseline during Treatment Period (up to Week 25)
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of investigational medicinal product (IMP), whether or not considered related to the IMP. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of IMP. TEAEs are defined as AEs starting after the time of first IMP administration up to and including 8 weeks (56 days) after the final dose.
Time frame: From Baseline to end of Safety Follow-Up Period (up to Week 31)
Percentage of Participants With TEAEs Leading to Withdrawal of Investigational Medicinal Product (ie, Study Discontinuation)

Documents are hosted by the registry — open the source record to download them.
Plan to share: Yes — Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
