Больные с  рецидивирующим/рефрактерным Ph-позитивным острым лимфобластным лейкозом (ОЛЛ) имеют плохой прогноз и ограниченные возможности лечения. У этой группы больных применяют терапию Т-клетками с химерным антигенным рецептором (chimeric antigen receptor, CAR-Т), моноклональными антителами (блинатумомаб, инотузумаб/озогамицин) в сочетании с ингибиторами тирозинкиназ. Однако при развитии рецидива или рефрактерности после применения одного из этих методов лечения не изучены долгосрочные результаты.</p></sec><sec><title>Цель</title><p>Цель: представить наблюдение применения анти-CD19 CAR T терапии после терапии блинатумомабом у больного с рецидивирующим течением Ph-позитивного ОЛЛ.</p></sec><sec><title>Основные сведения</title><p>Основные сведения. У больного в возрасте 28 лет был впервые установлен диагноз Ph-позитивного B-ОЛЛ (транскрипт p210) в 2014 г. В 1-й линии лечения ему проводили терапию по протоколу «ОЛЛ-2009» с иматинибом, трансплантацию аллогенных гемопоэтических стволовых клеток. Однако спустя 2 месяца выявлен первый молекулярный рецидив, иматиниб заменили на дазатиниб. В ноябре 2016 г. диагностирован второй рецидив, в 2017 г. — третий рецидив с поражением яичка и мутацией Т315I, начата терапия понатинибом. В 2022 г. развился 4-й костномозговой рецидив, проводилась терапия блинатумомабом (5 курсов) в сочетании с понатинибом. Однако после 5-го курса терапии отмечено появление лейкемидов, к терапии был добавлен асциминиб. Но клинический эффект не получен. Больному была проведена анти-CD19  CAR T терапия. Полный ответ на  CAR T клеточную терапию подтвержден на 28-й день после введения CAR T. Дальнейшее наблюдение на протяжении года продемонстрировало стойкий клинический ответ и персистенцию CD3-позитивных CAR T клеток. Приведенное клиническое наблюдение применения анти-CD19 CAR T клеточной терапии у больного СD19-позитивным комбинированным рецидивом В-ОЛЛ с массивным экстрамедуллярным компонентом после терапии блинатумомабом показало долгосрочную эффективность при сроке наблюдения 1 год.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Patients with relapsed/refractory (r/r) Ph-positive acute lymphoblastic leukemia (ALL) have a poor prognosis and limited treatment options. New promising immunotherapies using CAR T cells or monoclonal antibodies (blinatumomab, inotuzumab/ozogamicin) in combination with tyrosine kinase inhibitors are being used for this group of patients. However, long-term results have not been studied when relapse or refractoriness develops after the use of one of these methods.</p></sec><sec><title>Aim</title><p>Aim: to present a clinical observation of the use of anti-CD19 CAR T therapy after blinatumomab therapy in a patient with a relapsed course of Ph-positive acute lymphoblastic leukemia.</p></sec><sec><title>Main findings</title><p>Main findings. A 28-year-old patient was first diagnosed with Ph-positive B-ALL (transcript p210) in 2014. In the 1st line of treatment he was treated with therapy according to the protocol ‘ALL-2009’ with imatinib and allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, 2 months later the first molecular relapse was detected, and imatinib was replaced by dasatinib. In November 2016, a second relapse was diagnosed. In 2017, a third relapse with testicular involvement and T315I mutation was diagnosed, and therapy with ponatinib was initiated. In 2022, a 4th medullary relapse developed, and therapy with blinatumomab (5 courses) in combination with ponatinib was performed. After the 5th course of therapy, the appearance of leukaemides was noted, and asciminib was added to the therapy. However, no clinical effect was noted. The patient was treated with anti-CD19 CAR T therapy. A complete response to CAR T-cell therapy was confirmed on day 28 after CAR T administration. Further follow-up, over the course of one year, demonstrated stable clinical response and persistence of CD3-positive CAR T-cells. This case report of anti-CD19 CAR T cell therapy in a patient with CD19-positive combined relapse with massive extramedullary component after blinatumomab therapy demonstrated long-term efficacy with a 1-year follow-up.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Ph-позитивный острый лимфобластный лейкоз</kwd><kwd>блинатумомаб</kwd><kwd>анти-CD19 терапия</kwd><kwd>терапия Т-клетками с химерным антигенным рецептором</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ph-positive acute lymphoblastic leukemia</kwd><kwd>blinatumomab</kwd><kwd>anti-CD19 CAR T therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed in accordance with the state assignment № 056-00021-24-00 for the performance of scientific research of the Federal State Budgetary Institution “NMRC for Hematology” approved by the Ministry of Health of Russia on 14.01.2024.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Burmeister T., Schwartz S., Bartram C.R., et al.
