Recent advances in CAR T-cell therapy for lymphoma in China

Lymphoma is a hematologic malignancy which mainly consists of Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). Although systemic chemotherapy, radiotherapy, and other advanced therapeutics, including rituximab or immune checkpoint inhibitors, have improved the prognosis in recent decades, there are still a number of patients with relapsed or refractory (R/R) lymphoma with a poor prognosis. Chimeric antigen receptor (CAR) T-cell therapy has provided a curative option for patients with relapsed or refractory lymphoma. Numerous clinical trials have been conducted worldwide and presented inspiring results that give insight into this breakthrough therapy. The development of cancer cell therapy in China has been rapid in the past years and dominates the field with the USA. This review aims to summarize the published results of CAR T-cell therapy alone or in combination with other therapies in mainland China, both in R/R NHL and R/R HL (AU)

DC vaccine enhances CAR-T cell antitumor activity by overcoming T cell exhaustion and promoting T cell infiltration in solid tumors

Objective Great success has been achieved in CAR-T cell immunotherapy in the treatment of hematological tumors. However, it is particularly difficult in solid tumors, because CAR-T is difficult to enter interior and exert long-term stable immune effects. Dendritic cells (DCs) can not only present tumor antigens but also promote the infiltration of T cells. Therefore, CAR-T cells with the help of DC vaccines are a reliable approach to treat solid tumors. Methods To test whether DC vaccine could promote CAR-T cell therapy in solid tumors, DC vaccine was co-cultured with MSLN CAR-T cells. The in vitro effects of DC vaccine on CAR-T were assessed by measuring cell proliferation, cell differentiation, and cytokine secretion. Effects of DC vaccine on CAR-T were evaluated using mice with subcutaneous tumors in vivo. The infiltration of CAR-T was analyzed using immunofluorescence. The persistence of CAR-T in mouse blood was analyzed using real-time quantitative PCR. Results The results showed that DC vaccine significantly enhanced the proliferation potential of MSLN CAR-T cells in vitro. DC vaccines not only promoted the infiltration of CAR-T cells, but also significantly improved the persistence of CAR-T in solid tumors in vivo. Conclusion In conclusion, this study has demonstrated that DC vaccine can promote CAR-T therapy in solid tumors, which provides the possibility of widespread clinical application of CAR-T cells in the future (AU)

Chimeric antigen receptor T cells therapy in solid tumors

Chimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. Chimeric antigen receptor (CAR) is an engineered synthetic receptor of CAR-T, which give T cells the ability to recognize tumor antigens in a human leukocyte antigen-independent (HLA-independent) manner and enables them to recognize more extensive target antigens than natural T cell surface receptor (TCR), resulting in tumor destruction. CAR-T is composed of an extracellular single-chain variable fragment (scFv) of antibody, which serves as the targeting moiety, hinge region, transmembrane spacer, and intracellular signaling domain(s). CAR-T has been developing in many generations, which differ according to costimulatory domains. CAR-T therapy has several limitations that reduce its wide availability in immunotherapy which we can summarize in antigen escape that shows either partial or complete loss of target antigen expression, so multiplexing CAR-T cells are promoted to enhance targeting of tumor profiles. In addition, the large diversity in the tumor microenvironment also plays a major role in limiting this kind of treatment. Therefore, engineered CAR-T cells can evoke immunostimulatory signals that rebalance the tumor microenvironment. Using CAR-T therapy in treating the solid tumor is mainly restricted by the difficulty of CAR-T cells infiltrating the tumor site, so local administration was developed to improve the quality of treatment. The most severe toxicity after CAR-T therapy is on-target/on-tumor toxicity, such as cytokine release syndrome (CRS). Another type of toxicity is on-target/off-tumor toxicity which originates from the binding of CAR-T cells to target antigen that has shared expression on normal cells leading to damage in healthy cells and organs. Toxicity management should become a focus of implementation to permit management beyond specialized centers (AU)

Overcome tumor relapse in CAR T cell therapy

Chimeric antigen receptor (CAR) T cell therapy is a novel therapeutic approach that uses gene editing techniques and lentiviral transduction to engineer T cells so that they can effectively kill tumors. However, CAR T cell therapy still has some drawbacks: many patients who received CAR T cell therapy and achieve remission, still had tumor relapse and treatment resistance, which may be due to tumor immune escape and CAR T cell dysfunction. To overcome tumor relapse, more researches are being done to optimize CAR T cell therapy to make it more precise and personalized, including screening for more specific tumor antigens, developing novel CAR T cells, and combinatorial treatment approaches. In this review, we will discuss the mechanisms as well as the progress of research on overcoming plans. (AU)

A strategic reflection for the management and implementation of CAR-T therapy in Spain: an expert consensus paper

CAR-T cell therapy represents a therapeutic revolution in the prognosis and treatment of patients with certain types of hematological cancer. However, they also pose new challenges in the healthcare, regulatory and financial fields. The aim of the RET-A project was to undertake a strategic reflection on the management of CAR-T therapies within the Spanish National Health System, to agree on recommendations that will help to better deal with the new context introduced by these cell therapies in the present and in the future. This think tank involved 40 key agents and opinion leaders. The experts identified three great challenges for implementing advanced therapies in Spain: therapeutic individualisation, with a multidisciplinary approach; acceleration of access times, by minimizing bureaucracy; and increase in the number of centers qualified to manage the CAR-T therapies in the NHS. The experts agreed on the ideal criteria for designating those qualified centers. They also agreed on a comprehensive CAR-T care pathway with the timings and roles which would ideally be involved in each part of the process.

Síndrome de neurotoxicidad asociada a células inmunoefectoras: un enfoque terapéutico en el paciente crítico / Immune effector cell-associated neurotoxicity syndrome: A therapeutic approach in the critically ill

La inmunoterapia con células T modificadas con receptor quimérico antígeno-específico (chimeric antigen receptor conocida como [CAR-T]) está emergiendo como un tratamiento prometedor para enfermedades hematológicas. Así, las CAR-T dirigidas contra el complejo de diferenciación 19 han demostrado gran eficacia antitumoral contra neoplasias de células B resistentes a terapias convencionales. Sin embargo, la activación dirigida de la respuesta inmunitaria desata en ciertos casos complicaciones específicas graves y potencialmente mortales. Entre ellas cabe destacar el síndrome de liberación de citoquinas y el síndrome de toxicidad neurológica asociado a la terapia con células inmunoefectoras (Immune-effector cell associated neurotoxicity syndrome conocido como ICANS), siendo este último el objetivo de nuestra revisión. Aunque los mecanismos fisiopatológicos que conducen al ICANS son poco conocidos, existen factores clínicos y biológicos que aumentan el riesgo de desarrollo de neurotoxicidad asociada a la terapia CAR-T. El tratamiento se basa en medidas de monitorización y soporte, tratamiento con anticonvulsivantes, corticosteroides e ingreso en los servicios de medicina intensiva de forma precoz. Este artículo proporciona una revisión exhaustiva de la literatura disponible sobre el ICANS desde una perspectiva multidisciplinar, incluyendo recomendaciones de intensivistas, neurólogos y hematólogos formados en el cuidado de adultos críticamente enfermos (AU)

Immunotherapy with chimeric antigen-specific receptor modified T cells, known as CAR-T, is emerging as a promising approach to hematological malignancies. In this regard, CAR-T against human cluster of differentiation (CD) 19 has demonstrated antitumor efficacy in application to B cell neoplasms resistant to conventional therapy. However, activation of the immune system induces severe and specific complications which can prove life-threatening. These include cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome (known as ICANS) - the latter being the subject of the present review. Although the physiopathological mechanisms underlying ICANS are not well known, a number of clinical and biological factors increase the risk of developing neurotoxicity associated to CAR-T therapy. Treatment is based on close monitoring, measures of support, anticonvulsivants, corticosteroids, and early admission to intensive care. The present study offers a comprehensive review of the available literature from a multidisciplinary perspective, including recommendations from intensivists, neurologists and hematologists dedicated to the care of critically ill adults (AU)

Terapia con linfocitos T con receptor de antígeno quimérico (CAR-T) en pacientes con linfoma de célula B agresivo. Perspectiva actual tras una década de tratamiento / Chimeric antigen receptor T-cell (CAR-T) therapy in patients with aggressive B-cell lymphomas. Current outlook after a decade of treatment

La terapia con linfocitos T con receptor de antígeno quimérico (CAR-T) ha revolucionado el manejo de los pacientes con linfoma difuso de células grandes B (LDCGB) refractarios o en recaída tras inmunoquimioterapia. Esta estrategia consiste en modificar genéticamente los linfocitos T de los propios pacientes para favorecer el reconocimiento de los antígenos tumorales seleccionados. Actualmente, hay disponibles dos medicamentos CAR-T anti-CD19 aprobados en España para pacientes con LDCGB tras dos o más líneas de tratamiento sistémico previo y existen múltiples ensayos clínicos en marcha que investigan su uso en líneas de tratamiento más precoces. Tanto los ensayos clínicos pivotales como los datos de práctica asistencial poscomercialización han contribuido a definir el perfil de eficacia y seguridad de cada constructo, a identificar los principales factores pronósticos de respuesta y a optimizar el manejo de las distintas fases de esta terapia. Todos estos aspectos se repasan en esta revisión. (AU)

Chimeric antigen receptor T-cell (CAR-T) therapy has revolutionized the management of patients with diffuse large B-cell lymphoma (DLBCL) who are refractory or relapse after immunochemotherapy. This strategy consists in genetically modifying the patient's own T lymphocytes to favor the recognition of selected tumor antigens. Currently, we have two anti-CD19 CAR-T drugs approved in Spain for patients with DLBCL after two or more prior treatment lines and there are multiple ongoing clinical trials exploring earlier lines of treatment. Both clinical trials and post-marketing real-world data have contributed to better define the efficacy and safety profile of each construct, identifying the main prognostic response factors and improving the management of each step in this therapy. All these aspects are reviewed herein. (AU)

Gestión farmacoterapéutica de los medicamentosde terapias avanzadas / Pharmacotherapeutic management of advanced therapy medicinal products

Los medicamentos de terapia avanzada han emergido en los últimosaños como nuevas estrategias farmacoterapéuticas. En este contexto, los serviciosde farmacia hospitalaria nos hemos tenido que adaptar al nuevo retoque ha supuesto su inclusión en nuestra cartera de servicios dentro del complejoproceso farmacoterapéutico en el que están inmersos los pacientes.Todas las actividades que se desarrollan en los servicios de farmaciahospitalaria cumplen con una base legal establecida en nuestra legislacióny garantizan la calidad y seguridad tanto de los pacientes atendidos comode todos y cada uno de los medicamentos que se gestionan.Los medicamentos de terapia avanzada tienen unas característicasespeciales a considerar que van desde las fases iniciales de seleccióny evaluación de los pacientes candidatos y su modelo de financiación,basado en riesgo compartido, hasta una fragilidad en su manipulación querequiere de una adecuada y adaptada formación del personal implicadoen la logística para mantener su viabilidad, al necesitar unas condicionesde conservación, en ocasiones, a temperaturas de menos 180 ºC, en elcaso de las células T con receptores quiméricos de antígenos.Además, la utilización clínica de los medicamentos de terapia avanzadaha necesitado de documentos de consenso de las sociedades científicas utiliquepongan en valor el posicionamiento del farmacéutico hospitalario, comomiembro indispensable dentro del equipo multidisciplinar asistencial, y quegaranticen, como en cualquier otro medicamento, la trazabilidad, la correctaconservación y custodia y el seguimiento farmacoterapéutico asociado auna adecuada atención farmacéutica de nuestros pacientes, sin olvidar laimportancia de la creciente investigación clínica, necesaria e imprescindiblepara una incorporación segura de nuevas dianas terapéuticas.

Advanced therapy medicinal products have emerged in recentyears as new pharmacotherapeutic strategies. In this context, hospitalpharmacy services have had to adapt to the new challenges posed bythe inclusion of advanced therapies in their roster of services againstthe background of the complex pharmacotherapeutic process patientstypically go through.All the activities carried out in the hospital pharmacy services mustabide by the rules established in the Spanish legislation and ensure boththe quality of the different drugs they manage and the safety of every singlepatient.Advanced therapy medicinal products are associated certain peculiarities,including the need to select and evaluate potential candidates toreceive them; recourse to financing mechanisms based on risk sharing; andtheir extreme fragility, which means that the personnel in charge of handlingthem must be properly trained to maintain their viability and that specialstorage conditions, involving temperatures below 180 ºC in the case ofchimeric antigen receptor T cell therapies, must be maintained.In addition, use of advanced therapy medicinal products in the clinicalsetting has made it necessary for scientific societies to produce consensus documents recognizing the pivotal role of hospital pharmacists as indispensablemembers of the multidisciplinary healthcare team and ensuringthe same traceability, conservation, custody and pharmacotherapeuticalmonitoring standards imposed on other drugs to provide for adequate pharmaceuticalcare. Scientific societies have also highlighted the importance ofintensifying clinical research, an essential requirement for the safe incorporationof new therapeutic targets.The present document is intended to describe the challenges pharmacistsmay face when using advanced therapy medicinal products at thedifferent stages or processes in the patient’s clinical journey.

Characterization of a xenograft model for anti-CD19 CAR T cell studies

Purpose Chimeric antigen receptor (CAR) T cell development for B cell malignancies treatment has triggered a paradigm shift in oncology. The development of anti-CD19 CAR T cells relies primarily on a panel of cell line-derived xenograft models, including Raji cells; however, the behavior of this model is under debate. We attempted to characterize this lymphoma model and propose outcome measures for CAR T cell studies Methods Raji cell line was inoculated into NOG mice via intra-venous (IV), intra-peritoneal (IP), and subcutaneous (SC) routes with different inoculum sizes, and consequent clinical and histopathological outcomes were assessed. Results Inoculum sizes of 105–106 resulted in a complete take rate. The mice with IV and SC-inoculated Raji cells presented the shortest and longest survival among lymphoma-bearing mice, respectively (P < 0.01). The IP group had the highest number of both infiltrated organs (P < 0.05; compared to SC) and involvement of lymphatic sites (P < 0.05; compared to IV). The number of lymphoma lesions on the liver was higher in the IV compared to IP (P < 0.001) and SC (P < 0.05). Conclusion We demonstrate that the Raji cell line inoculation route could determine the xenograft model system behavior in terms of survival, tumor burden, and dissemination pattern and gives the model the specific features suitable for testing the specific hypothesis in CAR T cell therapy. We also conclude outcome measures for CAR T cell studies that do not require imaging techniques (AU)

Peripheral blood T-cell receptor repertoire as a predictor of clinical outcomes in gastrointestinal cancer patients treated with PD-1 inhibitor

Background Identifying valid biomarkers for patient selection impressively promotes the success of anti-PD-1 therapy. However, the unmet need for biomarkers in gastrointestinal (GI) cancers remains significant. We aimed to explore the predictive value of the circulating T-cell receptor (TCR) repertoire for clinical outcomes in GI cancers who received anti-PD-1 therapy. Methods 137 pre- and 79 post-treated peripheral blood samples were included. The TCR repertoire was evaluated by sequencing of complementarity-determining region 3 (CDR3) in the TRB gene. The Shannon index was used to measure the diversity of the TCR repertoire, and Morisita’s overlap index was used to determine TCR repertoire similarities between pre- and post-treated samples. Results Among all enrolled patients, 76 received anti-PD-1 monotherapy and 61 received anti-PD-1 combination therapy. In the anti-PD-1 monotherapy cohort, patients with higher baseline TCR diversity exhibited a significantly higher disease control rate (77.8% vs. 47.2%; hazard ratio [HR] 3.92; 95% confidence interval [CI] 1.14–13.48; P = 0.030) and a longer progression-free survival (PFS) (median: 6.47 months vs. 2.77 months; HR 2.10; 95% CI 1.16–3.79; P = 0.014) and overall survival (OS) (median: NA vs. 8.97 months; HR 3.53; 95% CI 1.49–8.38; P = 0.004) than those with lower diversity. Moreover, patients with a higher TCR repertoire similarity still showed a superior PFS (4.43 months vs. 1.84 months; HR 13.98; 95% CI 4.37–44.68; P < 0.001) and OS (13.40 months vs. 6.12 months; HR 2.93; 95% CI 1.22–7.03; P = 0.016) even in the cohort with lower baseline diversity. However, neither biomarker showed predictive value in the anti-PD-1 combination therapy cohort. Interestingly, the combination of TCR diversity and PD-L1 expression can facilitate patient stratification in a pooled cohort. Conclusion The circulating TCR repertoire can serve as a predictor of clinical outcomes in anti-PD-1 therapy in GI cancers (AU)

Programmable and multi-targeted CARs: a new breakthrough in cancer CAR-T cell therapy

CAR-T cell therapy, as a novel immunotherapy approach, has indicated successful results in the treatment of hematological malignancies; however, distinct results have been achieved regarding solid tumors. Tumor immunosuppressive microenvironment has been identified as the most critical barrier in CAR-T cell therapy of solid tumors. Developing novel strategies to augment the safety and efficacy of CAR-T cells could be useful to overcome the solid tumor hurdles. Similar to other cancer treatments, CAR-T cell therapy can cause some side effects, which can disturb the healthy tissues. In the current review, we will discuss the practical breakthroughs in CAR-T cell therapy using the multi-targeted and programmable CARs instead of conventional types. These superior types of CAR-T cells have been developed to increase the function and safety of T cells in a controllable manner, which would diminish the incidence of relevant side effects. Moreover, we will describe the capability of these powerful CARs in targeting multiple tumor antigens, redirecting the CAR-T cells to specific target cells, incrementing the safety of CARs, and other advantages that lead to promising outcomes in cancer CAR-T cell therapy (AU)

Inmunoterapia con células CAR-T en hematooncología pediátrica / Immunotherapy with CAR-T cells in paediatric haematology-oncology

A pesar de ser una enfermedad rara, el cáncer es la primera causa de mortalidad por enfermedad durante la edad pediátrica en los países desarrollados. En este momento, la irrupción de nuevos tratamientos como la inmunoterapia constituye un nuevo paradigma clínico y regulatorio. Uno de estos tipos de inmunoterapia es la inmunoterapia celular. En particular, los medicamentos de terapia avanzada con receptores antigénicos quiméricos en los linfocitos T (CAR-T), y en concreto las células CAR-T19, han supuesto un nuevo escenario en el abordaje de los tumores hematológicos, como la leucemia aguda linfoblástica y los linfomas de células tipo B. La aprobación por las autoridades regulatorias de tisagenlecleucel y axicabtagene ciloleucel, ha impulsado la puesta en marcha del Plan Nacional de Terapias Avanzadas-Medicamentos CAR-T en España, evidenciándose no solo la conveniencia de identificar los centros más adecuados para su administración, sino la necesidad de que estos sufran una profunda transformación para que su actividad asistencial se extienda en algunos casos a la capacidad de fabricación propia de este tipo de terapias. Los hospitales especializados en hematooncología pediátrica tienen por tanto el reto de evolucionar hacia un modelo asistencial que integre la inmunoterapia celular, dotándose de capacidad propia para gestionar todos los aspectos relativos al uso, fabricación y administración de estos nuevos tratamientos

Despite being a rare disease, cancer is the first cause of mortality due to disease during the paediatric age in the developed countries. The current, great increase in new treatments, such as immunotherapy, constitutes a new clinical and regulatory paradigm. Cellular immunotherapy is one of these types of immunotherapy. In particular, the advanced therapy drugs with chimeric antigen receptors in the T-lymphocytes (CAR-T), and particularly the CAR-T19 cells, has opened up a new scenario in the approach to haematology tumours like acute lymphoblastic leukaemia and the B-Cell lymphomas. The approval of tisagenlecleucel and axicabtagene ciloleucel by the regulatory authorities has led to the setting up of the National Plan for Advanced Therapies-CAR-T drugs in Spain. There is evidence of, not only the advantage of identifying the centres most suitable for their administration, but also the need for these to undergo a profound change in order that their healthcare activity is extended, in some cases, to the ability for the in-house manufacture of these types of therapies. The hospitals specialised in paediatric haematology-oncology thus have the challenge of progressing towards a healthcare model that integrates cellular immunotherapy, having the appropriate capacity to manage all aspects relative to their use, manufacture, and administration of these new treatments

Inmunoterapia adoptiva con linfocitos antivirales: métodos y resultados / Adoptive immunotherapy with antiviral T cells: methods and results

Las infecciones y reactivaciones virales siguen siendo una de las principales causas de morbimortalidad en pacientes sometidos a un trasplante alogénico de precursores hematopoyéticos. La inmunoterapia adoptiva de linfocitosT específicos de virus, del donante al paciente, ha demostrado su eficacia en el tratamiento antiviral en pacientes trasplantados que aún no tienen reconstituido su propio sistema inmune. Actualmente, y de acuerdo a los requerimientos de las correspondientes agencias que regulan la producción de estas terapias avanzadas personalizadas, se están optimizando la producción y la aplicación de estos productos celulares, de manera que cumplan con las normas de correcta fabricación (GMP) y sean seguros y efectivos en el tratamiento del paciente. Para facilitar su implementación es necesario entender los fundamentos de la producción y uso de los linfocitosT específicos de virus. En este trabajo hacemos una revisión de la evolución de la metodología en la producción linfocitosT antivirales y los trabajos que avalan su eficacia terapéutica, hasta llegar a las plataformas de producción actuales, cuya comercialización se está iniciando en España y que permiten, entre otros, la obtención de linfocitosT específicos para virus y células CAR-T de manera totalmente automatizada y en condiciones GMP. La implementación de estas nuevas metodologías en el sistema sanitario español sin duda facilitará la accesibilidad de los pacientes a todo un nuevo repertorio de terapias avanzadas

Viral infections and reactivations are one of the main causes of morbidity and mortality in patients who undergo allogeneic haematopoietic progenitor cell transplantation. Adoptive immunotherapy with virus-specific Tcells (from donor to patient) has shown efficacy in the antiviral treatment of patients who have undergone transplantation and whose immune system has not yet been reconstituted. Currently, and according to the requirements of the corresponding agencies that regulate the production of these advanced personalised therapies, the production and application of these cell products are being optimised in such a way that they comply with good manufacturing practice standards and are safe and effective for treating patients. To facilitate their implementation, we need to understand the foundations of producing and using virus-specific Tcells. This study reviews the evolution of the methodology for producing antiviral Tcells and the studies that support their therapeutic efficacy. The study covers up to the current production platforms, whose commercialisation has begun in Spain. These platforms will help obtain virus-specific Tcells and chimeric antigen receptor Tcells, among others, in a completely automated manner and under good manufacturing practice conditions. The implementation of these new methodologies in the Spanish healthcare system will undoubtedly facilitate patients' access to a new repertoire of advanced therapies

Criterios de respuesta metabólica a la inmunoterapia / Criteria of metabolic response to immunotherapy

La valoración de la respuesta a la terapia es una de las indicaciones más complejas de los estudios de imagen. Valorar la respuesta a la terapia de un paciente incluido en un ensayo clínico usualmente está sujeto a unos criterios de respuesta estandarizados para ese contexto. Sin embargo, en la práctica clínica habitual se realizan muchos estudios en los que la pregunta clínica es si el tratamiento que recibe el paciente está siendo o no efectivo. Responder a esta pregunta representa uno de los mayores retos de los especialistas en imagen, especialmente con la introducción de nuevas modalidades de tratamiento, cuyos efectos directos sobre el tejido tumoral son inicialmente poco conocidos. Tenemos un papel esencial en la introducción de nuevas terapias, valorando sus efectos y sus beneficios en las diferentes situaciones clínicas. El conocimiento de estos efectos ha llevado a desarrollar nuevos criterios de respuesta que, a pesar de ser aplicables únicamente en ensayos clínicos, nos ofrecen información de cómo interpretar los hallazgos en la práctica clínica

Therapy response assessment is one of the most challenging indications of imaging studies. In clinical trial patients is usually measured with standardized response criteria. However, in the clinical practice, many studies are carried out in which the clinical question is whether or not the treatment is being effective. Answering this question is one of the greatest challenges for diagnostic imaging physicians, especially when a new treatment modality is being introduced, whose effects on tumoral lesions are firstly poorly understood. We have an essential role in the introduction of new therapies, assessing their effects and benefits. The knowledge of these effects has led to the development of many response criteria that, despite being applicable only in clinical trials, offer us information on how to interpret the findings in clinical practice

CAR-T: luces y sombras / CAR-T: lights and shades

La terapia celular adoptiva está revolucionando el panorama de la terapéutica actual. La gestión de los medicamentos CAR-T supone un reto para el sistema nacional de salud (SNS), pues se trata de medicamentos complejos de un elevado impacto sanitario. En esta línea, la elaboración de protocolos fármaco-clínicos con criterios claramente definidos ayudará a un correcto posicionamiento y selección de los pacientes candidatos a estas terapias. Así mismo, la administración de estos fármacos debe realizarse en centros previamente seleccionados y cualificados para tal fin, garantizando la equidad en el acceso. Por otro lado, es prioritario un abordaje multidisciplinar de todos los pacientes que sean tratados con las terapias CAR-T. Finalmente es fundamental la evaluación y el registro constante de resultados, los cuales contribuirán a determinar el beneficio real de la terapia, reclamando la necesidad de precios equitativos para garantizar la sostenibilidad del SNS y el acceso a los pacientes previamente seleccionados

Adoptive cell therapy is revolutionizing the current therapeutic landscape. The management of CAR-T drugs is a challenge for The National Health System (NHS), as they are complex drugs with high impact on health. This way, the development of clinical pharmaceutical protocols with clearly defined criteria, will help in correct positioning and selection of patients candidates for these therapies. Likewise, administration of these drugs must be carried out in centers previously selected and qualified for this purpose, guaranteeing equity of access. On the other hand, a multidisciplinary approach of all patients treated with CAR-T therapies is a priority. Finally, the assessment and the constant result recording are essencial, since they will contribute to determining the real benefit of these therapies, claiming the need for equitable prices, guaranteeing the sustainability of the NHS and the access of previously selected patients to them
