Cellular and Gene Therapy product (CGT product) manufacturers are required by regulations to qualify sites performing cell collection and processing as part of their manufacturing processes. The use of audits to qualify a site is part of the traditional supplier quality models for drug products. Due to the rapid growth of the CGT industry in recent years, healthcare institutions and manufacturers are finding it difficult to manage the increasing workload and resources needed to support audits when they are applied to the provision of Cellular Starting Material (CSM) collection from patients/subjects for the purpose of manufacturing. To alleviate this audit burden, several manufacturers have applied risk-based approaches to determine the needs and scope of audits. The authors of this commentary recommend that all manufacturers utilize a risk-based assessment program when appropriate and explain the use of tools created to facilitate a risk-based approach to streamline and reduce duplicative audits. This approach and tools, created by The NextGen Industry Working Group (IWG) site certification workstream with representation from pharmaceutical and biotech companies, health care institutions, accrediting organizations, and other stakeholders, is aligned with proposals from other multistakeholder groups, including the ASTCT 80/20 Task Force. The tools aim to streamline the site qualification processes performed by each manufacturer, offering a standardized approach to audits or gap analysis assessments. Offering an abbreviated audit model for sites that have already attained accreditation through agencies such as the AABB (Association for the Advancement of Blood & Biotherapies) and FACT (Foundation for the Accreditation of Cellular Therapy), helping the manufacturer to focus on product-specific requirements rather than re-evaluating systems that have already been audited in great detail by other parties.

Chimeric antigen receptor (CAR) T-cell therapy has transformed survival outcomes in patients with relapsed and refractory large B-cell lymphoma (LBCL), but it is associated with a variety of side effects. This study examined changes in patient-reported quality of life (QoL) and toxicities, as well as risk factors for worse QoL and toxicities, in the first year after treatment. Patients with LBCL completed questionnaires assessing QoL and toxicity severity before infusion, and 90, 180, and 360 days after infusion. Mixed models were used to examine changes in QoL and toxicities over time, and clinical moderators of change in QoL and toxicities. Patients reported improvements in physical functioning and fatigue in the year after treatment (P values <.01), but there were no changes in pain, anxiety, or depression over time. Patients with active disease at day 90 reported more physical dysfunction at all postinfusion timepoints (Ps ≤ .01) compared to patients who responded to treatment. Similarly, patients with active disease at day 90 reported worsening depression over time, such that at day 360, depressive symptoms were worse for patients with active disease than patients without active disease (P = .02). Patients treated with 4+ lines of prior therapy reported worsening pain and anxiety over time, such that at day 360, both pain and anxiety were significantly worse for patients previously treated with 4 of more lines of therapy than patients treated with fewer lines of therapy (Ps ≤ .01). Regarding toxicities, patients reported decreasing overall toxicity burden up to day 180, with subsequent worsening at day 360 (P = .02). Most patients reported at least one or two grade 2 toxicities at each timepoint. Patients demonstrated unchanging or improved QoL after treatment with CAR T-cell therapy, but active disease and greater prior lines of therapy were associated with worse QoL outcomes over time. Toxicity severity also improved during the first 6 months post-treatment, but worsened thereafter, particularly among patients with active disease after treatment.

<div><div>Limited evidence suggests chronic graft-versus-host disease (cGvHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) increases healthcare resource utilization (HCRU) and costs. However, this burden has not been well characterized in England. This study assesses secondary care HCRU and costs for patients following allo HSCT in England with cGvHD and patients who did not develop graft-versus-host disease (GvHD). Further stratification was performed among patients who did or did not subsequently receive high-cost therapies for the treatment of cGvHD. This descriptive, retrospective cohort study used Hospital Episode Statistics (HES) data from April 2017 to March 2022. HES data captures information on reimbursed diagnoses and procedures from all National Health Service (NHS) secondary care admissions and attendances in England. High-cost drugs as defined by NHS England are recorded in HES, these drugs and other procedures including plasma exchange, were used to identify patients with cGvHD who were in receipt of high-cost therapies. HCRU and costs were described for patients with cGvHD following allo-HSCT (<em>n</em> = 721) and were matched with patients with no evidence of GvHD following allo-HSCT (<em>n</em> = 718). HCRU and costs were also described for the subset of patients with cGvHD (<em>n</em> = 198) following receipt of high-cost therapies and patients with cGvHD prior to or without such therapies (<em>n</em> = 523). A higher proportion of patients with cGvHD had at least one inpatient or intensive care unit (ICU) admission or emergency care attendance than patients without GvHD (inpatient: 74.6% versus 66.6%; emergency care: 39.3% versus 30.5%; ICU: 7.4% versus 4.7%; respectively); whilst the proportion of patients with an outpatient attendance were similar for both groups (outpatient: 80.3% versus 84.1%; respectively). The cost across all secondary care settings was higher for patients with cGvHD than patients without GvHD, with a mean cost of inpatient admissions of £17,339 per patient-year for those with cGvHD versus £8548 per patient-year in patients without GvHD. A higher proportion of patients who received high-cost therapies for the treatment of cGvHD had at least one secondary care admission or attendance, than patients who did not (inpatient: 85.4% versus 66.4%; ICU: 7.1% versus 5.4%; outpatient: 87.9% versus 76.7%; emergency care: 44.4% versus 36.5%; respectively). Patients who were treated with high-cost therapies for the treatment of cGvHD had a greater mean number (14.6 versus 8.2 per patient-year, respectively) for all-cause inpatient admissions after treatment than patients who did not. In all secondary care settings, the total cost per patient-year was higher for patients who received high-cost therapies for the treatment of cGvHD, than for those who did not. Patients who were treated with high-cost therapies for the treatment of cGvHD had a greater mean cost (£21,137 versus £15,956 per pati

Donor-specific anti-HLA antibodies (DSA) are an important cause of engraftment failure and may negatively impact survival outcomes of patients receiving allogeneic hematopoietic stem cell transplantation (HSCT) using an HLA-mismatched allograft. The incidence of DSA varies across studies, depending on individual factors, detection or identification methods and thresholds considered clinically relevant. Although DSA testing by multiplex bead arrays remains semiquantitative, it has been widely adopted as a standard test in most transplant centers. Additional testing to determine risk of allograft rejection may include assays with HLA antigens in natural conformation, such as flow cytometric crossmatch, and/or antibody binding assays, such as C1q testing. Patients with low level of DSA (<2,000 mean fluorescence intensity; MFI) may not require treatment, while others with very high level of DSA (>20,000 MFI) may be at very high-risk for engraftment failure despite current therapies. By contrast, in patients with moderate or high level of DSA, desensitization therapy can successfully mitigate DSA levels and improve donor cell engraftment rate, with comparable outcomes to patients without DSA. Treatment is largely empirical and multimodal, involving the removal, neutralization, and blocking of antibodies, as well as inhibition of antibody production to prevent activation of the complement cascade. Desensitization protocols are based on accumulated multicenter experience, while prospective multicenter studies remain lacking. Most patients require a full intensity protocol that includes plasma exchange, while protocols relying only on rituximab and intravenous immunoglobulin may be sufficient for patients with lower DSA levels and negative C1q and/or flow cytometric crossmatch. Monitoring DSA levels before and after HSCT could guide preemptive treatment when high levels persist after stem cell infusion. This paper aims to standardize current evidence-based practice and formulate future directions to improve upon current knowledge and advance treatment for this relatively rare, but potentially serious complication in allogeneic HSCT recipients.

Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative treatment for severe aplastic anemia (SAA). Existing guidance about HCT in SAA is primarily derived from expert reviews, registry data and societal guidelines; however, transplant-specific guidelines for SAA are lacking. A panel of SAA experts, both pediatric and adult transplant physicians, developed consensus recommendations using Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology employing a GRADE guideline development tool. The panel agrees with previous recommendations for the preferential use of bone marrow as a graft source and the use of rabbit over horse antithymocyte globulin (ATG) for HCT conditioning. Fludarabine containing regimens are preferred for patients at high risk of graft failure and those receiving matched unrelated or haploidentical donor transplant. Given advancements in HCT, the panel does not endorse the historical 40-year age cut-off for considering upfront HCT in adults, acknowledging that fit older patients may also benefit from HCT. The panel also endorses increased utilization of HCT by prioritizing matched unrelated or haploidentical donor HCT over immunosuppressive therapy in children and adults who lack a matched related donor. Finally, the panel suggests either calcineurin inhibitor plus methotrexate or post-transplant cyclophosphamide-based graft-versus-host disease (GVHD) prophylaxis for matched related or matched unrelated donor recipients. These recommendations reflect a significant advancement in transplant strategies for SAA and highlight the importance of ongoing and further research to revisit current evidence in terms of donor choice, conditioning chemotherapy, GVHD prophylaxis and post-transplant immunosuppression.
异基因造血细胞移植(HCT)是一种可能治愈重型再生障碍性贫血(SAA)的治疗方法。现有的 SAA 造血干细胞移植指南主要来自专家评论、登记数据和社会指南,但缺乏针对 SAA 的移植指南。一个由儿科和成人移植医师组成的 SAA 专家小组采用建议、评估、发展和评价分级(GRADE)方法,利用 GRADE 指南开发工具制定了共识建议。专家小组同意之前的建议,即优先使用骨髓作为移植物来源,以及在 HCT 调理中使用兔抗胸腺细胞球蛋白 (ATG) 而非马抗胸腺细胞球蛋白 (ATG)。对于移植失败风险较高的患者和接受配型非血缘关系或单倍体供体移植的患者来说,含氟达拉滨的方案是首选。鉴于造血干细胞移植技术的进步,专家小组不赞成在考虑成人前期造血干细胞移植时采用 40 岁这一历史分界线,并承认适合的老年患者也可从造血干细胞移植中获益。专家小组还赞同提高造血干细胞的利用率,在缺乏匹配的亲属供体的儿童和成人中,优先考虑匹配的非亲属或单倍体供体造血干细胞,而不是免疫抑制疗法。最后,专家小组建议对配型相关或配型无关的供体受者采用钙神经蛋白抑制剂加甲氨蝶呤或移植后环磷酰胺为基础的移植物抗宿主病(GVHD)预防疗法。这些建议反映了 SAA 移植策略的重大进展,并强调了持续开展进一步研究的重要性,以重新审视在供体选择、条件化疗、移植物抗宿主病(GVHD)预防和移植后免疫抑制方面的现有证据。

The panel agrees with previous recommendations for the preferential use of bone marrow as a graft source and the use of rabbit over horse antithymocyte globulin (ATG) for HCT conditioning. Fludarabine containing regimens are preferred for patients at high risk of graft failure and those receiving matched unrelated or haploidentical donor transplant. Given advancements in HCT, the panel does not endorse the historical 40-year age cut-off for considering upfront HCT in adults, acknowledging that fit older patients may also benefit from HCT. The panel also endorses increased utilization of HCT by prioritizing matched unrelated or haploidentical donor HCT over immunosuppressive therapy in children and adults who lack a matched related donor. Finally, the panel suggests either calcineurin inhibitor plus methotrexate or post-transplant cyclophosphamide-based graft-versus-host disease (GVHD) prophylaxis for matched related or matched unrelated donor recipients. These recommendations reflect a significant advancement in transplant strategies for SAA and highlight the importance of ongoing and further research to revisit current evidence in terms of donor choice, conditioning chemotherapy, GVHD prophylaxis and post-transplant immunosuppression.</div></div>","PeriodicalId":23283,"journal":{"name":"Transplantation and Cellular Therapy","volume":"30 12","pages":"Pages 1155-1170"},"PeriodicalIF":3.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we compare outcomes of older patients with primary diffuse large B-cell lymphoma of the central nervous system (PCNSL) undergoing autologous hematopoietic cell transplantation (autoHCT) with either thiotepa/carmustine (BCNU/Thio) or thiotepa/busulfan/cyclophosphamide (TBC) conditioning. We used a postpublication dataset made available by the Center for International Blood and Marrow Transplantation Research including patients who were ≥65 years in age with PCNSL and underwent autoHCT as consolidation with TBC or BCNU/Thio conditioning. Out of 147 patients; n = 84 received BCNU/Thio and n = 63 received TBC. The 1-year NRM in the BCNU/Thio group was 10% versus 22% in the TBC group (P = .05) and the 2-year relapse rate was 5% versus 5%, respectively (P = 1.00). The 2-year progression-free survival (PFS) in the BCNU/Thio group was 85% versus 71% in the TBC group (P = .05) and 2-year overall survival (OS) was 86% versus 74% (P = .08). In a multivariable regression model, BCNU/Thio was associated with a lower risk for NRM (hazard ratio [HR], 0.33, P = .009), improved PFS (HR, 0.41, P = .008) and OS (HR, 0.37, P = .007), but there was no association with relapse risk. We found that in older adults with PCNSL undergoing consolidation with autoHCT, BCNU/Thio conditioning is associated with lower NRM and improved OS compared to TBC.

The Third Annual Workshop of the American Society for Transplantation and Cellular Therapy (ASTCT) and National Marrow Donor Program (NMDP) ACCESS Initiative occurred on July 23 and 24, 2024. Content from the workshop is provided to inform the hematopoietic cell transplantation (HCT) and cellular therapy (CT) ecosystem about progress and direction of the collaborative. Highlights from the meeting are reviewed, including the inaugural Corporate Roundtable and Advocacy Day, new partnerships with non-profit organizations, and updates on projects from the Awareness, Poverty and Race and Ethnicity Inequity Committees. In addition, the Junior Faculty and Trainee Immersion Program–sponsored efforts in workforce diversity and physician advocacy are presented. Lastly, continued education was provided on patient and caregiver participation as well as community engagement. As it enters its third year, the ASTCT-NMDP ACCESS Initiative will transition from foundation building as a grass roots collaborative to intentional impact in reducing barriers and improving outcome disparities for all patients in need of HCT/CT. Enthusiasm for and participation in the ACCESS Initiative remain high. Both are needed to sustain progress in achieving its goal in enabling all patients in need to receive HCT/CT.
