Current Trends and Outcomes in Cellular Therapy Activity in the United States, Including Prospective Patient-Reported Outcomes Data Collection in the Center for International Blood and Marrow Transplant Research Registry

The Center for International Blood and Marrow Transplant Research (CIBMTR) prepares an annual set of summary slides to summarize the trends in transplantation and cellular therapies. For the first time in the 2023 summary slides, the CIBMTR incorporated data for patients receiving chimeric antigen receptor T cell (CAR-T) infusions. In addition, data on patient-reported outcomes (PROs) are included. This report aims to update the annual trends in US hematopoietic cell transplantation (HCT) activity and incorporate data on the use of CAR-T therapies. A second aim is to present and describe the development, implementation, and current status of PRO data collection. In August 2020, the CIBMTR launched the Protocol for Collection of Patient-Reported Outcomes Data (CIBMTR PRO Protocol). The CIBMTR PRO Protocol operates under a centralized infrastructure to reduce the burden to centers. Specifically, PRO data are collected from a prospective convenience sample of adult HCT and CAR-T recipients who received treatment at contributing centers and consented for research. Data are merged and stored with the clinical data and used under the governance of the CIBMTR Research Database Protocol. Participants answer a series of surveys developed by the Patient Reported Outcomes Measurement Information System (PROMIS) focusing on physical, social and emotional, and other measures assessing financial well-being, occupational functioning, and social determi- nants of health. To complement traditionally measured clinical outcomes, the surveys are administered at the same time points at which clinical data are routinely collected. As of September 2023, PRO data have been collected from 993 patients across 25 differ- ent centers. With the goal of incorporating these important patient perspectives into standard clinical care, the CIBMTR has added the PRO data to Data Back to Centers (DBtC). Through expanding the data types represented in the registry, the CIBMTR aims to support holistic research accounting for the patients' perspective in improving patient outcomes. CIBMTR PRO data aim to provide a foundation for future large-scale, popula- tion-level evaluations to identify areas for improvement, emerging disparities in access and health outcomes (eg, by age, race, and ethnicity), and new therapies that may impact current treatment guidelines. Continuing to collect and grow the PRO data is critical for understanding these changes and identifying methods for improving patients' quality of life.
