Liu W, Lin S, Zhu X, Yin L, Liu Q, Lei S, Feng B. Safety assessment of anti-B cell maturation antigen chimeric antigen receptor T cell therapy: a real-world study based on the FDA adverse event reporting system database. Front Immunol 2024; 15:1433075. [PMID: 39290710 PMCID: PMC11405296 DOI: 10.3389/fimmu.2024.1433075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Accepted: 08/09/2024] [Indexed: 09/19/2024] Open
Abstract
Background On April 18, 2024, the U.S. Food and Drug Administration officially required updating of the "boxed warning" for T cell malignancies for all chimeric antigen receptor T cell (CAR-T) therapies. Given the clinical significance of these therapies, a rigorous safety assessment is paramount. However, comprehensive real-world safety studies have been lacking for the newly marketed CAR-T products idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel), which target B cell maturation antigen, especially regarding the risk of secondary malignancies. Therefore, we aimed to thoroughly analyze the adverse events (AEs) information in the FDA Adverse Event Reporting System (FAERS) database to comprehensively understand the safety risks of ide-cel and cilta-cel. Methods We extracted AE reports related to ide-cel and cilta-cel from the FAERS database (https://fis.fda.gov/extensions/FPD-QDE-FAERS/FPD-QDE-FAERS.html.) from January 1, 2019 to December 31, 2023. Disproportionality analysis and Bayesian analysis were used to identify risk signals across subgroups and specific cases (including for death and secondary malignancies). Weibull distribution analysis was employed to determine the time to AE onset. Results A total of 695 AE reports for ide-cel and 848 for cilta-cel were included in the FAERS database. This analysis identified 81 positive signals for ide-cel and 74 for cilta-cel. Notably, comparisons with the drug labels revealed "unexpected signals," including febrile bone marrow aplasia (reporting odds ratio=69.10; confidence interval 39.12-122.03) and plasma cell myeloma (12.45; 8.18-18.95) for ide-cel, and increased serum ferritin (24.98; 8.0-77.58) and large intestine perforation (18.57; 5.98-57.69) for cilta-cel. Both drugs showed a higher AE incidence among male recipients and patients aged ≥65 years, although female recipients faced a greater risk. Most AEs occurred at the early stage of administration. However, secondary malignancies were detected for both drugs, primarily occurring one-year post-administration. Conclusion This study provides a foundation for understanding the safety profile of CAR-T cell therapy, particularly in relation to the emergence of secondary malignancies. Such insights are helpful for clinical decision-making and the safe and effective utilization of these therapeutic agents.

Abstract
The field of cancer treatment has evolved significantly over the last decade with the emergence of next-generation therapeutic antibodies. Conventional treatments like chemotherapy pose significant challenges, including adverse side effects. Monoclonal antibodies have paved the way for more targeted and effective interventions. The evolution from chimeric to humanized and fully human antibodies has led to a reduction in immunogenicity and enhanced tolerance in vivo. The advent of next-generation antibodies, including bispecific antibodies, nanobodies, antibody-drug conjugates, glyco-engineered antibodies, and antibody fragments, represents a leap forward in cancer therapy. These innovations offer increased potency, adaptability, and reduced drug resistance. Challenges such as target validation, immunogenicity, and high production costs exist. However, technological advancements in antibody engineering techniques provide optimism for addressing these issues. The future promises a paradigm shift, where ongoing research will propel these powerful antibodies to the forefront, revolutionizing the fight against cancer and creating new preventive and curative treatments. This review provides an overview of three next-generation antibody-based molecules, namely bispecific antibodies, antibody-drug conjugates, and nanobodies that have shown promising results in cancer treatment. It discusses the evolution of antibodies from conventional forms to next-generation molecules, along with their applications in cancer treatment, production methods, and associated challenges. The review aims to offer researchers insights into the evolving landscape of next-generation antibody-based cancer therapeutics and their potential to revolutionize treatment strategies.

Abstract
Multiple myeloma (MM) is an incurable plasma cell malignancy. In the context of the current standard of care therapies in Canada, outcomes among patients with relapsed/refractory multiple myeloma (RRMM), particularly those with triple-class (or more) refractory disease remain poor. Immunotherapies have significantly changed the treatment landscape of MM. Since 2021, two BCMA-targeting CAR T-cell therapy products have been approved for RRMM-namely Idecabtagene vicleucel (Ide-cel) (ABECMA®) and Ciltacabtagene autoleucel (Cilta-cel) (CARVYKTI®), both of which are available in the US and Europe. Although they have shown unprecedented efficacy in RRMM, their clinical and logistical limitations must be acknowledged. MM CAR T-cell therapy is likely to be approved in Canada soon. Therefore, it is timely that we review the latest evidence for commercially available CAR T-cell therapy in multiple myeloma, with a focus on its relevance and impact in the Canadian setting. There will be challenges to access and strategies must be in place to ensure equitable care for all Canadians with MM. Alongside haematologists working in the immune effector cell therapy programs, providers in the community will also play a role in the ongoing monitoring and management of long-term side effects including opportunistic infections and late neurotoxicity.

Abstract
INTRODUCTION Ciltacabtagene autoleucel (cilta-cel), a BCMA-targeting CAR-T therapy, is approved in the United States and Europe for patients with relapsed/refractory multiple myeloma (RRMM) and ≥1 prior line of therapy (LOT), including a proteasome inhibitor and an immunomodulatory drug, and are lenalidomide refractory. AREAS COVERED We examine recent long-term data in heavily pretreated RRMM (LEGEND-2, CARTITUDE-1) and earlier LOTs (CARTITUDE-4) compared with standard therapy and discuss the rationale for investigating cilta-cel as frontline therapy for transplant-eligible and transplant-ineligible patients (CARTITUDE-5, CARTITUDE-6). EXPERT OPINION CAR-T therapies can improve outcomes for patients with MM across different LOTs. CARTITUDE-1 and CARTITUDE-4 have set a new bar for efficacy, with median PFS of 34.9 months in heavily pretreated patients (CARTITUDE-1) and a 74% relative risk reduction for progression/death versus standard care in patients with 1-3 prior LOTs (CARTITUDE-4), with manageable safety. Response rates were consistent between the two studies: 98% in CARTITUDE-1 and approaching 100% for infused patients in CARTITUDE-4. Cilta-cel could be a key treatment choice for patients with RRMM after first LOT. Clinical trials investigating frontline cilta-cel therapy will provide valuable insights into optimizing treatment pathways with the aim to potentially cure MM.

Abstract
Recently, many new therapies have improved the outcomes of patients with relapsed and/or refractory multiple myeloma (RRMM). Nevertheless, recurrence is still unavoidable, and better treatment choices for RRMM are urgently needed. The clinical success of Chimera antigen receptor (CAR) T cell therapy in many hematological diseases, including leukemia and lymphoma, has drawn considerable attention to RRMM. As CAR T cell therapy continues to mature and challenge traditional therapies, it is gradually changing the treatment paradigm for MM patients. The B cell maturation antigen (BCMA), expressed in malignant plasma cells but not normal ones, is an ideal target for MM treatment, due to its high expression. The US Food and Drug Administration (FDA) and European Medicines Agency (EMA) has approved two BCMA-targeting CAR T cell products, idecabtagene vicleucel (Ide-cel) and ciltacabtagene autoleucel (Cilta-cel), for use in RRMM. In this review, we focus on data from RRMM patients involved in clinical trials of Ide-cel and Cilta-cel and discuss the present situation and future direction of CAR T cell therapy for this condition.

Abstract
The literature is limited regarding outcomes in older adults and frail patients receiving BCMA-directed chimeric antigen receptor T cell therapy (CAR-T) for relapsed or refractory multiple myeloma. Here we describe the safety and efficacy of CAR-T in these clinically important subgroups treated in a real-world setting. Frailty was defined as a frail score ≥2 using the simplified frailty index (score based on age + Eastern Cooperative Oncology Group [ECOG] Performance Status + Hematopoietic Cell Transplantation Comorbidity Index [HCT-CI]). Of the 136 patients analyzed (age range, 41 to 81 years), 83 (61%) were considered frail at the time of CAR-T infusion. Compared to the nonfrail group, the frail group had higher proportions of patients with renal insufficiency (18% versus 6%), high-risk cytogenetics (45% versus 35%), extramedullary disease (51% versus 43%), and ECOG Performance Status ≥2 (18% versus 2%), and worse HCT-CI (3 versus 1). Although patients in the frail group had a higher incidence of immune effector cell-associated neurotoxicity syndrome (ICANS) (39% versus 17%), the incidences of all- grade cytokine release syndrome (CRS), as well as high-grade CRS and ICANS, were similar in the 2 groups. With a median follow-up of 7 months, the median progression-free survival was 6.9 months in the frail group versus 11.1 months in the nonfrail group (P = .028). The median overall survival was 14 months in the frail group and was not reached in the nonfrail group (P = .025). This study highlights the tolerable safety and reasonable efficacy of CAR-T for frail myeloma patients in a real-world practice. Although the frail patients did not experience any excessive high-grade toxicities, they did have inferior efficacy outcomes.

Abstract
Chimeric antigen receptor (CAR)-T cells have recently emerged as a powerful therapeutic approach for the treatment of patients with chemotherapy-refractory or relapsed blood cancers, including acute lymphoblastic leukaemia, diffuse large B cell lymphoma, follicular lymphoma, mantle cell lymphoma and multiple myeloma. Nevertheless, resistance to CAR-T cell therapies occurs in most patients. In this Review, we summarize the resistance mechanisms to CAR-T cell immunotherapy by analysing CAR-T cell dysfunction, intrinsic tumour resistance and the immunosuppressive tumour microenvironment. We discuss current research strategies to overcome multiple resistance mechanisms, including optimization of the CAR design, improvement of in vivo T cell function and persistence, modulation of the immunosuppressive tumour microenvironment and synergistic combination strategies.

Abstract
Despite continued advances that have led to improved survival of patients with multiple myeloma (MM) over the years, MM remains largely incurable with overall survival in patients who have progressed after proteasome inhibitor, immunomodulatory drug, and anti-CD38 monoclonal antibody therapy measured in months. Better understanding of the immunopathology of MM has led to the discovery of newer treatment targets like B-cell maturation antigen (BCMA). BCMA is a tumor necrosis factor receptor superfamily expressed on normal B-lymphocytes and malignant plasma cells with a vital role in proliferation, maturation, and differentiation of normal and malignant plasma cells. Antibody drug conjugates, chimeric antigen receptor (CAR) T-cells and bispecific T-cell engagers targeting the BCMA antigen are now available within and outside of clinical trials for treatment of triple class refractory MM. This review article focuses on the evolution, safety, efficacy, and limitations of BCMA-directed CAR T-cell therapies. It also discusses the challenges unveiled by the incorporation of these CAR T-cells in the treatment paradigm of MM and deliberates on the future of CAR T-cell therapy within MM.

Abstract
OBJECTIVE Summarize the background, clinical trials, and place in therapy for the newly Food and Drug Administration (FDA) approved and forthcoming bispecific antibodies for relapsed/refractory (R/R) multiple myeloma. DATA SOURCES A search of the PubMed database was conducted using the following search terms: B-cell maturation antigen (BCMA), teclistamab, myeloma, BsAbs, GPRC5D, and bispecific. Ongoing clinical trials as well as abstracts from ASH and ASCO evaluating the efficacy and safety of novel agents were evaluated. Prescribing information was also reviewed. SUMMARY For patients with R/R multiple myeloma who have failed available therapies, treatment options are limited and survival is short. The FDA recently approved teclistamab, a T-cell-redirecting bispecific antibody, in patients with R/R multiple myeloma who have failed four prior lines of therapy. Teclistamab targets both CD3 expressed on T-cells and BCMA expressed on the surface of myeloma cells, mediating T-cell activation and lysis of plasma cells that express BCMA. Accelerated approval was granted based upon the results of the MajesTEC-1 study, which showed a durable response in a high proportion of heavily pretreated patients. Teclistamab is the first bispecific antibody approved for use in patients with multiple myeloma and the fourth approved agent targeting BCMA. Additional T-cell redirecting bispecific antibodies for use in multiple myeloma are also currently being studied. CONCLUSION Teclistamab is the newest agent granted FDA approval for use in R/R multiple myeloma and represents a promising new option for patients. Ongoing trials are investigating teclistamab and other novel bispecific antibodies in the upfront and R/R setting.

Abstract
B-cell maturation antigen (BCMA) is a clinically validated target for multiple myeloma. T-cell engineered with chimeric antigen receptors (CARs) directed against BCMA have demonstrated robust therapeutic activity in clinical trials, but toxicities remain a significant concern for a subset of patients, supporting continued investigation of other engineered T-cell platforms that may offer equal efficacy with an improved toxicity profile. The authors recently described a BCMA-specific, T-cell-centric synthetic antigen receptor, the T-cell antigen coupler (TAC) receptor, that can be used to engineer T-cell with robust anti-myeloma activity. Here the authors describe the creation of a fully humanized BCMA-specific TAC receptor. Single-chain variable fragments (scFvs) were developed from BCMA-specific F(ab)s that were identified in a fully human phage display library. Twenty-four configurations of the F(ab)s were evaluated in a medium-throughput screening using primary T-cell, and a single F(ab), TRAC 3625, emerged as the most robust following in vitro and in vivo evaluation. An optimized BCMA-specific TAC receptor was developed through iterations of the BCMA-TAC design that evaluated a next-generation TAC scaffold sequence, different domains connecting the TAC to the 3625 scFv and different orientations of the TRAC 3625 heavy and light variable regions.

Abstract
Currently used stratification models in myeloma precursor disease as well as staging systems and response criteria in myeloma have limitations including failure to identify functionally high-risk myeloma patients. B-cell maturation antigen, a transmembrane glycoprotein required for long-lived plasma cells, is specific and expressed by myeloma cells. When it sheds from the surface of myeloma cells it can be measured in the blood as serum (sBCMA) and correlated with clinical outcomes in myeloma precursor disease as well as in active myeloma. We performed a literature review using PubMed and found 825 articles since 1992 of which any articles related to sBCMA were reviewed. These studies show the potential of sBCMA to become an important biomarker in myeloma. Here, we describe the potential advantages of sBCMA in the biology, diagnosis, prognosis, and surveillance of myeloma, while also reviewing the challenges that lie ahead before it can be implemented as a clinical tool.

Current and Future Perspectives for Chimeric Antigen Receptor T Cells Development in Poland. Biomedicines 2022; 10:biomedicines10112912. [PMID: 36428480 PMCID: PMC9687915 DOI: 10.3390/biomedicines10112912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/03/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022] Open
Abstract
Chimeric antigen receptor T (CAR-T) cells are genetically modified autologous T cells that have revolutionized the treatment of relapsing and refractory haematological malignancies. In this review we present molecular pathways involved in the activation of CAR-T cells, describe in details the structures of receptors and the biological activity of CAR-T cells currently approved for clinical practice in the European Union, and explain the functional differences between them. Finally, we present the potential for the development of CAR-T cells in Poland, as well as indicate the possible directions of future research in this area, including novel modifications and applications of CAR-T cells and CAR-natural killer (NK) cells.

Abstract
Flow cytometry has been indispensable in diagnosing B cell lymphoma and plasma cell neoplasms. The advances in novel multicolor flow cytometry have also made this technology a robust tool for monitoring minimal/measurable residual disease in chronic lymphocytic leukemia and multiple myeloma. However, challenges using conventional gating strategies to isolate neoplastic B or plasma cells are emerging due to the rapidly increasing number of antibody therapeutics targeting single or multiple classic B/plasma cell-lineage markers, such as CD19, CD20, and CD22 in B cells and CD38 in plasma cells. This review is the first of a two-part series that summarizes the most current targeted therapies used in B and plasma cell neoplasms and proposes detailed alternative approaches to overcome post-targeted therapy analysis challenges by flow cytometry. The second review in this series (Chen et al.) focuses on challenges encountered in the use of targeted therapy in precursor B cell neoplasms.

Ghanem B, Shi L. The Economic Burden of CAR T Cell Therapies Ciltacabtagene Autoleucel and Idecabtagene Vicleucel for the Treatment of Adult Patients with Relapsed or Refractory Multiple Myeloma in the US. BioDrugs 2022; 36:773-780. [PMID: 36167952 DOI: 10.1007/s40259-022-00557-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/13/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND Two chimeric antigen receptor-engineered T (CAR T) cell therapy drugs were recently approved for the treatment of patients with relapsed or refractory multiple myeloma (rrMM). Their financial impact, however, is poorly described. OBJECTIVE The aim was to evaluate the economic burden of CAR T cell therapies ciltacabtagene autoleucel and idecabtagene vicleucel for the treatment of rrMM patients after at least four lines of therapy, and to compare the annual cost of these CAR T cell therapies over a hypothetical 1-million-member health plan from the US healthcare payer perspective. PATIENTS AND METHODS The annual economic burden of ciltacabtagene autoleucel and idecabtagene vicleucel was estimated using data from pivotal clinical trials. The costs of drug acquisition, administration, and adverse event (AE) management were extracted from the IBM-Micromedex Red Book online, the Centers for Medicare & Medicaid Services fee schedules, and a review of the literature. We used descriptive statistics for the analysis. RESULTS The annual costs (US dollars) of drug acquisition, administration, and AE management per patient were $465,000, $60,167, and $40,368 and $419,500, $61,250, and $47,270 for ciltacabtagene autoleucel and idecabtagene vicleucel, respectively. The total annual cost was higher for ciltacabtagene autoleucel ($565,534) than for idecabtagene vicleucel ($528,020). However, the total annual cost in a hypothetical 1-million-member plan was less with ciltacabtagene autoleucel, by $1.8 million. CONCLUSION This study found that the CAR T cell gene therapies ciltacabtagene autoleucel and idecabtagene vicleucel for rrMM represent a significant economic burden for healthcare payers in the USA.
