About this study

Official title: Pyruvate Kinase Deficiency Global Longitudinal Registry: Patient-Reported Outcomes

The primary objective of this study is to understand and characterize the health-related quality of life (HRQoL) and disease burden of adult participants with PK deficiency receiving routine clinical care. This study is an observational (i.e., noninterventional), longitudinal, multicenter, global registry for participants with PK deficiency, a rare nonspherocytic hemolytic anemia.

This study will be open for enrollment for 2 years and all enrolled participants will be followed prospectively for up to 96 weeks.

Data will be collected from participants who have provided informed consent and authorization pursuant to applicable laws and regulations.

Read the detailed description

Participants aged ≥18 years and previously enrolled in Study AG348-C-008 (NCT03481738) will be eligible to participate in this study. Data will be submitted via electronic patient-reported outcomes (ePRO) application.

All data collection efforts will abide by this protocol and be prospectively disclosed in the study informed consent. This study, with the appropriate participant (and or parent/guardian) consent/assent, may incorporate retrospective data from other properly consented studies done for the purpose of examining the longitudinal natural history of PK deficiency.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from Baseline in Pyruvate Kinase Deficiency Diary (PKDD) Score

    The PKDD is a 7-item measure of the core signs and symptoms of PK deficiency. The score range is 25 to 76, with higher scores indicating a higher disease burden.

    Measured: Baseline, up to Day 672

  2. Change from Baseline in Pyruvate Kinase Deficiency Impact Assessment (PKDIA) Score

    The PKDIA is a 12-item measure of the impacts of PK deficiency on patients' HRQoL. The score range is 30 to 76, with higher scores indicating a higher disease burden.

    Measured: Baseline, up to Day 672

  3. Change from Baseline in Work Productivity and Activity Impairment Questionnaire: Specific Health Problem (WPAI: SHP) 2.0 Score

    WPAI:SHP is a 6-question participant-rated questionnaire to determine the amount of absenteeism, presenteeism, work productivity loss, and daily activity impairment attributable to PK deficiency for a period of 7 days prior to each visit. It yields 4 sub-scores: work time missed (absenteeism), impairment while working (presenteeism or reduced on-the-job effectiveness), overall work impairment (work productivity loss or absenteeism plus presenteeism) and activity impairment (daily activity impairment). These sub-scores are transformed to impairment percentages (range from 0 to 100), with higher numbers indicating greater impairment and less productivity.

    Measured: Baseline, up to Day 672

  4. Change from Baseline in Functional Assessment of Cancer Therapy-Anemia (FACT-An)

    FACT-An is composed of five subscales: Physical Well-Being [score range 0-28], Social/Family Well-Being [score range 0-28], Emotional Well-Being [score range 0-24], and Functional Well-Being [score range 0-28] and specific questions concerning anemia [score range 0-80]. The score at each item is summed. The sum is multiplied by the number of items in the subscale and then divided by the number of items answered. This produces the subscale score. The subscale scores are added to derive a total score [score range 0-188]. A higher score indicates better quality of life.

    Measured: Baseline, up to Day 672

Questions about this trial

What is this clinical trial studying?

An observational study of Pyruvate Kinase Deficiency and Pyruvate Kinase Deficiency Anemia, run by Agios Pharmaceuticals, Inc. at 5 sites in 5 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 2 inclusion and 1 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: stopped early, as of the sponsor's last update on 7 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, Italy, Netherlands, Spain, United Kingdom. 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.

Are results available for this study?

The study was stopped early (reason given: Lack of enrollment and participant compliance with surveys.). Results are not available in the source record.

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?

Change from Baseline in Pyruvate Kinase Deficiency Diary (PKDD) Score (time frame: Baseline, up to Day 672). The study lists 4 primary outcomes in all. 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 7 Sep 2023.
