Associations Between Frequent Plasmapheresis, Biomarkers, and Health Outcomes: A 2-Year National Prospective Cohort Study
Westat
Summary
The Plasma Protein Therapeutics Association (PPTA) sponsors the Cohort of Repeat Donor Experiences (CORE) Study. This is a prospective, observational cohort study that will follow Source Plasma donors for up to 2 years during the main study (anticipated to begin in summer 2026) and up to 3 months during the pilot launching in mid-March 2026. This study aims to confirm a lack of negative health effects Source Plasma donors may experience as a result of frequent plasmapheresis. The study will use data obtained through self-report surveys for the duration of the study along with periodic whole blood sample collections to test for CRP, ferritin, and IgG.
Description
The study employs a two-phase prospective design: (1) data collected before and 48-72 hours after an initial plasma Data will be collected through electronic surveys, real-time illness reports, biomarker analyses, and extracts of Blood Establishment Computer Software (BECS) records including donor screening and operational collection processing variables, if available. Study staff (Study Coordinators employed by the plasma collection companies and Westat central study staff) will engage with participants directly and Westat systems will be used for data collection. The pilot study is planned t…
