Abstract Background Chimeric antigen receptor (CAR) T cell therapy has had great success in treating patients with relapsed or refractory B cell malignancies, with CD19-targeting therapies now approved in many countries. However, a subset of patients fails to respond or relapse after CD19 CAR T cell therapy, in part due to antigen loss, which has prompted the search for alternative antigen targets. CD22 is another antigen found on the surface of B cells. CARs targeting CD22 alone or in combination with other antigens have been investigated in several pre-clinical and clinical trials. Given the heterogeneity and small size of CAR T cell therapy clinical trials, systematic reviews are needed to evaluate their efficacy and safety. Here, we propose a systematic review of CAR T cell therapies targeting CD22, alone or in combination with other antigen targets, in B cell malignancies. Methods We will perform a systematic search of EMBASE, MEDLINE, Web of Science, Cochrane Register of Controlled Trials, clinicaltrials.gov, and the International Clinical Trials Registry Platform. Ongoing and completed clinical trials will be identified and cataloged. Interventional studies investigating CD22 CAR T cells, including various multi-antigen targeting approaches, in patients with relapsed or refractory B cell malignancies will be eligible for inclusion. Only full-text articles, conference abstracts, letters, and case reports will be considered. Our primary outcome will be a complete response, defined as absence of detectable cancer. Secondary outcomes will include adverse events, overall response, minimal residual disease, and relapse, among others. Quality assessment will be performed using a modified Institute of Health Economics tool designed for interventional single-arm studies. We will report a narrative synthesis of clinical studies, presented in tabular format. If appropriate, a meta-analysis will be performed using a random effects model to synthesize results. Discussion The results of the proposed review will help inform clinicians, patients, and other stakeholders of the risks and benefits of CD22 CAR T cell therapies. It will identify gaps or inconsistencies in outcome reporting and help to guide future clinical trials investigating CAR T cells.

Background: Chimeric antigen receptor (CAR) T cell therapy is a novel treatment modality for patients with R/R LBCL. Limited information exists regarding patients' views of CAR T cell therapy. Our research aimed to better understand patients' needs by capturing their expectations/concerns, current well-being, and treatment experiences during the beginning stages of CAR T cell therapy in the clinical trial setting. Methods: Patients with R/R LBCL from 2 ongoing trials of the investigational, CD19-directed CAR T cell therapy liso-cel (TRANSCEND WORLD [NCT03484702] or PLATFORM [NCT03310619]) were invited to participate in an optional interview component. Semistructured interviews were conducted to gain insight about patients' experience with CAR T cell therapy in the clinical trials. Interviews of ≤1 hour (in-person or over the phone) were conducted in parallel with screening procedures (interview 1), after leukapheresis (interview 2), and up to 3 days after liso-cel infusion (interview 3). Interviews were audio recorded and transcribed. MAXQDA (VERBI GmbH, Berlin, Germany) qualitative analysis software was used to manage and thematically organize interview transcript data to identify key concepts related to each research objective. Previously reported results of interview 1 showed a high perception of unmet needs, lack of alternative options, and expectations for positive outcomes. The analysis presented here primarily focused on interviews 2 and 3. Denominators shown in the Results vary by question as some patients skipped questions. Results: A total of 75 interviews were analyzed, including 35, 24, and 16 patients at interviews 1, 2, and 3, respectively, across sites in the US (n = 14), Europe (n = 26), and Japan (n = 2). Among 42 patients who completed ≥1 interview, the mean age was 62 years and 69% were male. Treatment Experience: Of 24 patients who completed interview 2, 22 (92%) reported positive experiences during leukapheresis and 16 (67%) reported the procedure was as expected. Patients thought the most difficult part of leukapheresis was the length of the procedure (n = 8/21 [38%]). Of 15 patients who provided feedback on lymphodepleting chemotherapy, a majority reported that it was as expected (n = 8 [53%]) or easier than expected (n = 3 [20%]); when asked about the most difficult part, many patients (n = 7/17 [41%]) discussed side effects (eg, nausea, fatigue, and lack of appetite). Of patients who described liso-cel infusion as different than expected, differences included easier (n = 12/13 [92%]) or quicker (n = 3/12 [25%]) than expected, and 5/12 (42%) reported few/no side effects within 3 days post-infusion. Over half of patients (n = 8/14 [57%]) reported that the infusion, as a whole, was not difficult. Changes over Time: At interviews 1, 2, and 3, respectively, 47% (n = 14/30), 47% (n = 9/19), and 69% (n = 9/13) of patients reported hoping for successful treatment. Similarly, patients generally had fewer concerns later in the process, with 21 (64%) and 11 (33%) of 33 patients reporting side-effect and treatment efficacy concerns, respectively, during interview 1 vs 5 (33%) and 3 (20%) of 15 patients, respectively, during interview 3. At time of enrollment, most patients (n = 21/34 [62%]) were able to function normally or with minimal impact from their lymphoma, although most reported some symptoms like fatigue, pain, or stomach problems. At interview 1, 14 (40%) of 35 patients were employed; most patients reported no changes in their work life at interviews 2 (n = 19/20 [95%]) and 3 (n = 11/12 [92%]). From enrollment to immediately post-infusion, the physical health of most patients remained stable (n = 4/16 [25%]) or deteriorated (n = 9/16 [56%]). However, most patients (n = 14/15 [93%]) reported feeling positive at interview 3. Conclusions: This study provided the unique opportunity to gather feedback directly from patients participating in clinical trials of liso-cel therapy, specifically during the initial treatment stages. The overall impression of the treatment was positive, with most patients reporting that study procedures were easier than expected. The results of this qualitative research provide useful insight into the motivations, expectations, and experiences of patients with R/R LBCL receiving liso-cel therapy, which can inform the design of health care support systems and future clinical trials to better meet patients' needs.

Aims: Within the past few years, there has been tremendous growth in clinical trials of chimeric antigen receptor (CAR) T-cell therapies. Unlike those of many small-molecule pharmaceuticals, CAR T-cell therapy clinical trials are fraught with risks due to the use of live cell products. The aim of this study is to reach a consensus with experts on the most relevant set of risks that practically occur in CAR T-cell therapy clinical trials. Methods: A Delphi method of consensus development was used to identify the risks in CAR T-cell therapy clinical trials, comprising three survey rounds. The expert panel consisted of principal investigators, clinical research physicians, members of institutional ethics committees, and Good Clinical Practice managers. Results: Of the 24 experts invited to participate in this Delphi study, 20 participants completed Round 1, Round 2, and Round 3. Finally, consensus (defined as >80% agreement) was achieved for 54 risks relating to CAR T-cell clinical trials. Effective interventions related to these risks are needed to ensure the proper protection of subject health and safety. Conclusion: The Delphi method was successful in gaining a consensus on risks relevant to CAR T-cell clinical trials in a geographically diverse expert association. It is hoped that this work can benefit future risk-based quality management in clinical trials and can potentially promote the better development of CAR T-cell therapy products.

Abstract Background: Chimeric antigen receptor T cell (CAR-T) therapy is an adoptive T cell immunotherapy that employs the genetically modified T cell to attack the cancer cell. It is widely studied across various hematological and solid organ malignancies. Several autologous CD19 CAR-T cell therapy constructs are now approved for various B cell lymphomas, including aggressive B cell lymphomas, indolent follicular lymphoma and mantle cell lymphoma, and acute lymphoblastic leukemia (ALL). Autologous CD19 CAR-T cell therapy has unprecedented success in relapsed and refractory disease. Long time to manufacture (2-5 weeks) and manufacture failure are challenges associated with risk of interim death and deterioration of CAR-T candidates with rapidly progressive disease. T cell fitness of the autologous product in heavily pretreated patients is also potentially compromised. To overcome these shortcomings, universal "off the shelf" allogeneic CAR-T cell therapy constructs are being developed and studied. Donor sources include healthy donors and cord or induced pluripotent stem cells (iPSCs). These CAR-T constructs have additional gene modifications to mitigate the risk of rejection and graft versus host disease (GVHD). We performed a systematic review and meta-analysis to assess the safety and efficacy of allogeneic CD19 CAR-T cell therapy. Methods: Four databases (Web of Science/MEDLINE/PubMed, Embase, and Cochrane Registry of Controlled Trials) were searched for this systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines using MeSH terms and keywords for "Receptors, Chimeric antigen" OR "Artificial-T-cell receptor" OR "immunotherapy, adoptive" OR "CD-19". Our search produced 3506 articles and after removing duplicates, 2243 records were screened. After excluding reviews and irrelevant articles, we included 8 prospective trials of allogeneic CD-19 CAR-T cell therapy enrolling two or more than two patients from Jan 2013 to Nov 2020. We also searched ASH 2020 abstracts to include any additional trials. The methodological quality of the included studies was evaluated using NIH quality assessment tool. Inter-study variance was calculated using the Der Simonian-Laird Estimator. Proportions along with 95% confidence Interval (CI) were extracted to compute pooled analysis using the 'meta' package by Schwarzer et al. in the R programming language (version 4.16-2). Results: A total of 68 patients from 8 studies were evaluated. Median age was 22.5 (4.8-64) years. (Table 1) The median follow-up time was 10 (2-18) months with median number of prior therapies of 3.2 (2-11) as reported by 5 studies. Underlying diagnosis was acute lymphocytic lymphoma (n=49, 72%), chronic lymphocytic leukemia (n=6, 9%), and non-Hodgkin lymphoma (n=13, 19%). The pooled overall response rate (ORR) was 77% (95% CI 0.63-0.89, I 2 =22%, n=68) with a complete response (CR) of 75% (95% CI 0.57-0.90, I 2 =48%, n=65). The pooled incidence of cytokine release syndrome grade I/II and grade III/IV was 53% (95% CI 0.16-0.89, I 2 =89%, n=65) and 10% (95% CI 0.01-0.25, I 2 =50%, n=65) respectively. Neurotoxicity grade I/II was 12% (95%CI 0.01-0.30, I 2 =47%, p=0.09, n=47) and GVHD grade I/II was 8% (95%CI 0.01-0.19, I 2 =0%, p=0.57 n=53). None of the clinical trials reported the duration of response. Conclusion: "Off the shelf" universal CAR-T therapy is early in development. Our available data suggest that allogeneic CD19 CAR-T constructs offer high ORR and CR rates with acceptable safety profiles. GVHD was mainly low grade (grade I-II). Given these findings, allogeneic CAR-T cell therapy is an attractive option to improve timely access compared to available autologous therapy. Extensive preclinical research to develop novel constructs and several phase I/II clinical trials are ongoing to shape the future of "off the shelf" CAR-T cell therapy. Figure 1 Figure 1.

Abstract Chimeric antigen receptor (CAR) T-cell therapy has achieved significant success in the treatment of hematological malignancies. In recent years, fast-growing CAR T clinical trials have actively explored their potential application scenarios. According to the data from the clinicaltrials.gov website, China became the country with the most registered CAR T trials in September 2017. As of June 30, 2020, the number of registered CAR T trials in China has reached 357. In addition, as many as 150 other CAR T trials have been registered on ChiCTR. Although CAR T therapy is flourishing in China, there are still some problems that cannot be ignored. In this review, we aim to systematically summarize the clinical practice of CAR T-cell therapy in China. This review will provide an informative reference for colleagues in the field, and a better understanding of the history and current situation will help us more reasonably conduct research and promote cooperation.

ABSTRACT Chimeric antigen receptor (CAR) T cell therapy has emerged as a revolutionary treatment option for highly aggressive B cell malignancies. Clinical trials of CD19 CAR T cells for the management of relapsed and/or refractory non-Hodgkin lymphoma (NHL) have shown markedly improved survival and response rates. The goal of this review is to evaluate whether the results from these clinical trials are reflective of real-world practices through the analysis of published literature of the commercially available CAR T cell products. We have found that despite the significantly different patient characteristics, the adverse events and response rates of real-world patients were similar to those of the clinical trials. Of interest, several groups excluded from the clinical trials, such as patients with HIV infection, chronic viral hepatitis, and secondary CNS (central nervous system) lymphoma, had case reports of promising outcomes.

Purpose: The aim is to review the current advances in designing safer and more efficient CAR-T cells and discuss the future research possibilities for the treatment of both hematological malignancies and solid tumors. Study Design: An extensive review was carried out on the basic structure of CARS, current advances to design safer and more efficient CAR-T cells, and future research possibilities for the treatment of both hematological malignancies and solid tumors. Results: Encouragement of chimeric antigen receptor-T (CAR-T) cell therapy as one of adoptive immunotherapy is increasingly important in recent years. Its preparation is based on the genetic modification of individual T cells. The innovation of the functional intracellular signaling domain is a critical part of the genetically modified T cells and requires a long journey of development that has resulted in several improvements in the safety and effectiveness of CAR-T cells. CAR-T cell therapy can be modified rapidly and has great and strong application potential according to a large number of global clinical trials. This article briefly describes the basic structure and design of CARs and discusses current trends in the development of safer and more efficient CAR-T cells for the treatment of both hematological and solid malignancies and looks forward to future research possibilities. Conclusion: It is concluded that conclude that the prospect of this technology lies in CAR-T cell engineering which can overcome aggressive TMEs and recruiting an endogenous tumor response. The final task for researchers in this field is to carry out clinical trials and secure the funding needed to complete their clinical trials. This immunotherapy continues to progress and more records of successful malignancy eradication occur.

Despite the discoveries of numerous agents including next generation proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies, multiple myeloma (MM) remains an incurable disease. The field of myeloma treatment in refractory or relapsed patients after standard therapy entered a new era due to the B-cell maturation antigen (BMCA) targeted approach. BCMA is a member of the tumor necrosis factor receptor family with high expression in mature B-lymphocytes and plasma cells. Given the understanding of BCMA mechanism of action in MM, BCMA plays a promising role as a therapeutic target. Several clinical trials are underway to evolve the current BCMA targeted treatment concept such as antibody-drug conjugates (ADCs), bispecific T cell engagers (BITEs) and chimeric antigen receptor (CAR) T cell therapy. Current results of representative BCMA trials may close the gap of the unmet clinical need to further improve the outcome of heavily pretreated MM patients with the potency to change the paradigm in newly diagnosed and refractory MM. This comprehensive review will give an update on various BMCA targeted treatment modalities (ADCs, BITEs, CAR T cell therapy) and its existing results on efficacy and safety from preclinical and clinical trials.

Chimaeric antigen receptor (CAR) T-cell therapies, as one of the cancer immunotherapies, have heralded a new era of treating cancer. The accumulating data, especially about CAR-modified T cells against CD19 support that CAR T-cell therapy is a highly effective immune therapy for B-cell malignancies. Apart from CD19, there have been many trials of CAR T cells directed other tumour specific or associated antigens (TSAs/TAAs) in haematologic malignancies and solid tumours. This review will briefly summarize basic CAR structure, parts of reported TSAs/TAAs, results of the clinical trials of CAR T-cell therapies as well as two life-threatening side effects. Experiments in vivo or in vitro, ongoing clinical trials and the outlook for CAR T-cell therapies also be included. Our future efforts will focus on identification of more viable cancer targets and more strategies to make CAR T-cell therapy safer.
