Worldwide Network for Blood and Marrow Transplantation Recommendations for Establishing a Hematopoietic Stem Cell Transplantation Program in Countries with Limited Resources, Part II: Clinical, Technical, and Socioeconomic Considerations.

The development of hematopoietic stem cell transplantation (HSCT) programs can face significant challenges in most developing countries because such endeavors must compete with other government health care priorities, including the delivery of basic services. Although this is may be a limiting factor, these countries should prioritize development of the needed expertise to offer state-of-the-art treatments, including transplantation, by providing financial, technological, legal, ethical, and other needed support. This would prove beneficial in providing successful programs customized to the needs of their population and potentially provide long-term cost savings by circumventing the need for their citizens to seek care abroad. The costs of establishing an HSCT program and the costs of the HSCT procedure itself can be substantial barriers in developing countries. In addition, socioeconomic factors intrinsic to specific countries can influence access to HSCT, patient eligibility for HSCT, and timely utilization of HSCT center capabilities. This report describes recommendations from the Worldwide Network for Blood and Marrow Transplantation for establishing HSCT programs, with a specific focus on developing countries, and identifies challenges and opportunities for providing this specialized procedure in resource-constrained settings.

Engaging Patients in Setting a Patient-Centered Outcomes Research Agenda in Hematopoietic Cell Transplantation.

The goal of patient-centered outcomes research (PCOR) is to help patients and those who care for them make informed decisions about healthcare. However, the clinical research enterprise has not involved patients, caregivers, and other nonproviders routinely in the process of prioritizing, designing, and conducting research in hematopoietic cell transplantation (HCT). To address this need the National Marrow Donor Program/Be The Match engaged patients, caregivers, researchers, and other key stakeholders in a 2-year project with the goal of setting a PCOR agenda for the HCT community. Through a collaborative process we identified 6 major areas of interest: (1) patient, caregiver, and family education and support; (2) emotional, cognitive, and social health; (3) physical health and fatigue; (4) sexual health and relationships; (5) financial burden; and (6) models of survivorship care delivery. We then organized into multistakeholder working groups to identify gaps in knowledge and make priority recommendations for critical research to fill those gaps. Gaps varied by working group, but all noted that a historical lack of consistency in measures use and patient populations made it difficult to compare outcomes across studies and urged investigators to incorporate uniform measures and homogenous patient groups in future research. Some groups advised that additional pre-emptory work is needed before conducting prospective interventional trials, whereas others were ready to proceed with comparative clinical effectiveness research studies. This report presents the results of this major initiative and makes recommendations by working group on priority questions for PCOR in HCT.

Current trends and outcomes in cellular therapy activity in the United States, including prospective Patient Reported Outcomes data collection within the CIBMTR registry.

BACKGROUND: Center for International Blood and Marrow Transplant Research (CIBMTR) prepares an annual set of summary slides to detail the trends in transplantation and cellular therapies. For the first time in the 2023 summary slides, CIBMTR incorporates data for patients receiving chimeric antigen receptor T-cell (CAR-T) infusions. In addition, the data on patient-reported outcomes (PROs) is also included. OBJECTIVES: This report aims to update the annual trends in US HCT activity and incorporate data on the use of CAR-T therapies. Here we also aim to present and describe the development, implementation, and current status of the PRO data collection. STUDY DESIGN: In August 2020, 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 burden to centers. Specifically, PRO data is collected from a prospective convenience sample of adult HCT and CAR-T patients 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 others measures assessing financial well-being, occupational functioning, and social determinants of health. To complement traditionally measured clinical outcomes, the surveys are administered at the same timepoints that clinical data is routinely collected. RESULTS: As of September 2023, PRO data from 993 patients across 25 different centers has been collected. With the goal of incorporating these important patient perspectives into standard clinical care, CIBMTR has added the PRO data to Data Back to Centers (DBtC). Through expanding the data types represented in the registry, CIBMTR aims to support holistic research accounting for the patient perspective in improving patient outcomes. CONCLUSION: PRO data at CIBMTR aims to provide the foundation for future large scale, population-level evaluations to determine 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 patient quality of life.

Bringing Patient and Caregivers Voices to the Clinical Trial Chorus: A Report From the BMT CTN Patient and Caregiver Advocacy Task Force.

The Blood and Marrow Transplant Clinical Trials Network (BMT CTN), funded by the National Heart, Lung, and Blood Institute and the National Cancer Institute for more than 2 decades, is focused on improving the outcomes of hematopoietic cell transplantation (HCT) and other cellular therapies. It answered critical questions about conditioning intensity, donor choice, graft-versus-host disease prevention and treatment, and relapse mitigation strategies in a manner made possible by an extensive network of centers that have enrolled more than 16,000 patients to more than 55 trials. Although the BMT CTN has engaged patients in a variety of ways since its establishment, there is a growing realization that increasing that engagement and including caregivers offers many additional benefits to patients and investigators alike. Bringing the voice of patients and caregivers to clinical trial design is likely to enhance trial participation and reduce barriers to recruitment/retention. Unless clinical trials are designed with unique considerations of patients who have socioeconomic and access challenges, these populations will remain under-represented in HCT trials with limited generalizability of results. The next main frontier in our field is patient and caregiver access to high-quality HCT facilities coupled with the opportunity to participate in relevant, meaningful clinical research. In 2021, the BMT CTN Executive Committee convened a Patient and Caregiver Advocacy Task Force with a diverse membership representing a variety of stakeholders. The charge to the Task Force was to provide achievable recommendations for incorporating patient input at all steps of clinical trial development from initial concept to dissemination of results. Four focus areas were identified: (1) patient and caregiver input in research portfolio; (2) patient engagement in informed consent, protocol development and trial conduct; (3) communication to patients about trial progress, primary outcomes and secondary analyses; and (4) increased awareness among patients who may be considering BMT or cell therapy about BMT CTN trials. Three specific initiatives were considered as high priority by the Task Force: Fostering patient and caregiver engagement in development of the research portfolio and protocols; Developing communication plans for ongoing studies; and Simplifying the process for informed consent to make it more patient friendly. The BMT CTN has established a patient and caregiver advocacy committee that is tasked with developing concrete steps to incorporate recommendations of the BMT CTN Task Force in its current and future work. The BMT CTN recognizes patient and caregivers are valuable partners whose voice will enhance the conduct of impactful trials in BMT and cell therapy.

Supportive care of hematopoietic cell transplant patients.

Hematopoietic cell transplant survivors face a number of challenges including low energy and stamina, "chemo-brain" and emotional distress, and late effects that can compromise functioning or lead to early mortality. This session will review the most recent interventions and recommendations to avoid or mitigate these complications.

Updated Trends in Hematopoietic Cell Transplantation in the United States with an Additional Focus on Adolescent and Young Adult Transplantation Activity and Outcomes.

Hematopoietic cell transplantation (HCT) has been successfully used to treat many malignant and nonmalignant conditions. As supportive care, donor selection, and treatment modalities evolve, documenting HCT trends and outcomes is critical. This report from the Center for International Blood and Marrow Transplant Research (CIBMTR) provides an update on current transplantation activity and survival rates in the United States. Additional data on the use and outcomes of HCT in the adolescent and young adult (AYA) population are included. AYA patients more frequently receive peripheral blood stem cell grafts than pediatric patients, which may reflect differences in practice in pediatric versus adult treatment centers. The proportions of donor types also differ those in adult and pediatric populations. Outcomes for patients in the AYA age range are similar to those of pediatric patients for acute myelogenous leukemia but worse for acute lymphoblastic leukemia. Outcomes for both leukemias are better in AYA patients compared with older adults. Comparing the time periods 2000 to 2009 and 2010 to 2019 revealed significant improvement in overall survival across the age spectrum, but the greatest improvement in the AYA age group.

Defining the intensity of conditioning regimens: working definitions.

Defining conditioning regimen intensity has become a critical issue for the hemopoietic stem cell transplant (HSCT) community. In the present report we propose to define conditioning regimens in 3 categories: (1) myeloablative (MA) conditioning, (2) reduced-intensity conditioning (RIC), and (3) nonmyeloablative (NMA) conditioning. Assignment to these categories is based on the duration of cytopenia and on the requirement for stem cell (SC) support: MA regimens cause irreversible cytopenia and SC support is mandatory. NMA regimens cause minimal cytopenia, and can be given also without SC support. RIC regimens do not fit criteria for MA or NMA regimens: they cause cytopenia of variable duration, and should be given with stem cell support, although cytopenia may not be irreversible. This report also assigns commonly used regimens to one of these categories, based upon the agents, dose, or combinations. Standardized classification of conditioning regimen intensities will allow comparison across studies and interpretation of study results.
