Remuneration of donors for cell and gene therapies: an update on the principles and perspective of the World Marrow Donor Association.

The cell and gene therapy (CGT) sector has witnessed significant advancement over the past decade, the inception of advanced therapy medicinal products (ATMPs) being one of the most transformational. ATMPs treat serious medical conditions, in some cases providing curative therapy for seriously ill patients. There is interest in pivoting the ATMP development from autologous based treatments to allogenic, to offer faster and greater patient access that should ultimately reduce treatment costs. Consequently, starting material from allogenic donors is required, igniting ethical issues associated with financial gains and donor remuneration within CGT. The World Marrow Donor Association (WMDA) established the Cellular Therapy Committee to identify the role WMDA can play in safeguarding donors and patients in the CGT field. Here we review key ethical principles in relation to donating cellular material for the CGT field. We present the updated statement from WMDA on donor remuneration, which supports non-remuneration as the best way to ensure the safety and well-being of donors and patients alike. This is in line with the fundamental objective of the WMDA to maintain the health and safety of volunteer donors while ensuring high-quality stem cell products are available for all patients. We acknowledge that the CGT field is evolving at a rapid pace and there will be a need to review this position as new practices and applications come to pass.

Genetic Findings of Potential Donor Origin following Hematopoietic Cell Transplantation: Recommendations on Donor Disclosure and Genetic Testing from the World Marrow Donor Association.

Following hematopoietic cell transplantation (HCT), recipients are subjected to extensive genetic testing to monitor the efficacy of the transplantation and identify relapsing malignant disease. This testing is increasingly including the use of large gene panels, which may lead to incidental identification of genetic and molecular information of potential donor origin. Deciphering whether variants are of donor origin, and if so, whether there are clinical implications for the donor can prove challenging. In response to queries from donor registries and transplant centers regarding best practices in managing donors when genetic mutations of potential donor origin are identified, the Medical Working Group of the World Marrow Donor Association established an expert group to review available evidence and develop a framework to aid decision making. These guidelines aim to provide recommendations on predonation consenting, postdonation testing of recipients, and informing and managing donors when findings of potential donor origin are identified in recipients post-transplantation. It is recognized that registries will have different access to resources and financing structures, and thus whenever possible, we have made suggestions on how recommendations can be adapted.

Serious Stem Cell Donation Events and Recipient Adverse Reactions Related to Severe Acute Respiratory Syndrome Coronavirus 2: Review of Reports to the World Marrow Donor Association.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has deeply impacted hematopoietic stem cell (HSC) donation and transplantation. Numerous changes in practice have been introduced, and monitoring the impact of these changes on donations and transplantations is of vital importance. As part of a global response to this pandemic, the World Marrow Donor Association (WMDA) asked that its member registries and cord blood banks submit SARS-CoV-2-related adverse events to the WMDA-operated Serious Product Events and Adverse Reactions (SPEAR) database. Here we review SARS-CoV-2-related SPEAR events that occurred in 2020. The WMDA SPEAR Committee reviewed reports submitted via an online tool. The Committee reviewed each report following the European Union definitions of a serious adverse event or reaction and determined the imputability and its impact. Reports submitted in 2020 were included in this analysis. A TOTAL OF: 74 such reports were received, and events were classified as donor-related (n = 41; 55.4%), recipient-related (n = 3; 4.1%), technical issues (n = 31; 41.8%), or transport-related issues (n = 4; 5.4%). Five cases appeared in multiple categories. The most frequently reported adverse events were of cells being unused. Many of these cases were caused by the uncoupling of the donation and transplantation consequent on the cryopreservation of products, as well as technical issues related to cell viability. Experience in some registries suggests that these issues have become less frequent as transplantation centers have become used to the changes in practice. Lessons learned include the importance of confirming recipient eligibility before the start of donor mobilization or collection and of minimizing the time between cell collection and transplantation. Transplantation centers should familiarize themselves with the expected cell losses when peripheral blood stem cell and bone marrow products are cryopreserved and should have validated viability assays in place for quality assurance. Reassuringly, there were no reports of donors becoming severely unwell because of G-CSF or transmission of SARS-CoV-2 to recipients and only 1 report of complete failure of transport of a donation.

User perspectives on a psychosocial blended support program for partners of patients with amyotrophic lateral sclerosis and progressive muscular atrophy: a qualitative study.

BACKGROUND: Partners are often the main caregivers in the care for patients with amyotrophic lateral sclerosis (ALS) and progressive muscular atrophy (PMA). Providing care during the progressive and fatal disease course of these patients is challenging and many caregivers experience feelings of distress. A blended psychosocial support program based on Acceptance and Commitment Therapy was developed to support partners of patients with ALS and PMA. The aim of this qualitative study is to gather insight into experiences with different components of the support program (program evaluation) and to discover what caregivers gained from following the program (mechanisms of impact). METHODS: Individual in-depth interviews, about caregivers' experiences with the support program were conducted with 23 caregivers of ALS/PMA patients enrolled in a randomized controlled trial designed to measure the effectiveness of the blended psychosocial support program. The program, performed under the guidance of a psychologist, consists of psychoeducation, psychological and mindfulness exercises, practical tips and information, and options for peer contact. Interviews were audio-recorded, transcribed verbatim and analyzed thematically. RESULTS: The program evaluation showed that caregivers perceived each component of the program as beneficial but ambivalent reactions were expressed about the mindfulness exercises and peer contact functions. Caregivers expressed the need for a more personalized program with respect to the order and timing of the modules and wanted to continue the support program for a longer time. The main mechanism of impact of the program that caregivers reported was that they became more aware of their own situation. They further indicated that the program helped them to perceive control over the caregiving situation, to accept negative emotions and thoughts, to be there for their partner and feel acknowledged. CONCLUSIONS: The blended psychosocial support program for caregivers of patients with ALS/PMA is valued by caregivers for enhancing self-reflection on their challenging situation which stimulated them to make choices in line with their own needs and increased their feeling of control over caregiving. The different components of the program were overall appreciated by caregivers, but the mindfulness and peer support components should be further adapted to the needs of the caregivers.
