The promising efficacy of a risk-based letermovir use strategy in CMV-positive allogeneic hematopoietic cell recipients.

Letermovir is the first approved drug for cytomegalovirus (CMV) infection prophylaxis in adult patients who are CMV positive undergoing allogeneic hematopoietic cell transplantation (allo-HCT). Because CMV infection risk varies from patient to patient, we evaluated whether a risk-based strategy could be effective. In this single-center study, all consecutive adult patients who were CMV positive and underwent allo-HCT between 2015 and 2021 were included.

Tisagenlecleucel (Kymriah™) and axicabtagene ciloleucel (Yescarta™) are the first representatives of a new class of gene therapies produced by ex-vivo genetic modification of human autologous T lymphocytes, now using viral vectors. In 2020, there are three independent CAR-T cell databases in France: DESCAR-T (database supported by LYSARC, GRAALL and the IFM), ProMISe (EBMT database) and ATIH (database of the Agence Technique de l'Information sur l'Hospitalisation). Only the EBMT database is common to France and the French-speaking countries that are members of the SFGM-TC.

[Reporting data of patients receiving CAR T cell therapy into the EBMT registry: Guidelines of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)].

Tisagenlecleucel (Kymriah™) and axicabtagene ciloleucel (Yescarta™) are the first two approved drug products that belong to of a new class of therapies manufactured through an industrial process that includes the ex vivo genetic modification of human autologous T lymphocytes with viral vectors. Since CAR-T Cells qualify as gene therapy medicinal products, there is a requirement for long-term (15 years) follow-up of treated patients. As part of a global initiative aiming at a better use of continental registries to study the outcome of homogeneous groups of patients, EMA issued a positive opinion on the use of the EBMT registry to capture LTFU of patients treated with CAR-T Cell in EU Member states.

[How to capture cytogenetic and molecular abnormalities into ProMISe database for hematological malignancies: Guidelines from the francophone society of bone marrow transplantation and cellular therapy (SFGM-TC)].

In an effort to standardize hematopoietic stem cell allograft procedures, the Francophone bone marrow transplantation and Cell Therapy Society (SFGM-TC) organized the 9th Allograft Harmonization Practice Workshop in Lille in September 2018. The purpose of these workshops is to propose a consensual attitude to the centers that wish it. In this workshop, we discuss how to capture the cytogenetic and molecular abnormalities of acute leukaemias, myelomas, myelodysplasias, myeloproliferative syndromes and myelodysplastic/myeloproliferative syndromes in the database common to all European transplant centers called ProMISe and managed by the European Society for Blood and Marrow Transplantation (EBMT).

[Harmonization of data coding in post-transplant follow-up - "GVHD, complications and additional treatments": Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)].

The quality of the information provided in post-transplant follow-up is necessary to obtain a coherent and exploitable database. Since the beginning of 2017, three forms (Med-B-allograft) have been available: the first month (Day 0), Day 100 (second report) and an annual follow-up report. Recommendations for follow-up were addressed in the 2014 harmonization workshop, "Harmonization of Data Coding…".
