The AURORA-RU Phase IV observational Russian study was initiated to evaluate the efficacy of atezolizumab in patients with urothelial carcinoma resistant to platinum-based chemotherapy. This article is based on an analysis conducted at a median follow-up of 60.7 months and provides data on treatment efficacy in Russian patients receiving second-line and subsequent lines of systemic therapy.</p> <p><bold>Aim.</bold> To evaluate the clinical efficacy of atezolizumab monotherapy in patients with urothelial carcinoma of the upper and lower urinary tract progressing on platinum-based chemotherapy in a real-world clinical setting. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Secondary endpoints included subgroup analyses of efficacy based on the line of therapy (including the subgroup with early progression after neo/adjuvant chemotherapy [NACT/ACT]), age cohort, metastatic sites, and primary tumor location (bladder vs. upper urinary tract).</p> <p><bold>Materials and methods.</bold> The study included data from 152 patients with verified muscle-invasive locally advanced and metastatic urothelial carcinoma who received PD-L1 inhibitor (atezolizumab) monotherapy across 13 centers in the Russian Federation between 2019 and 2025. Atezolizumab treatment was administered to patients who progressed on platinum-based chemotherapy. More than half of the patients (55.9 %) were over 65 years of age. The cohort consisted of 75.0 % men and 25.0 % women. The majority of patients (78.3 %) had a primary tumor located in the bladder. PD-L1 inhibitor therapy was administered as second-line treatment in 57.9 % of cases, while one in five patients (21.7 %) received third-line treatment. In 86.8 % of cases, treatment was administered without prior assessment of PD-L1 expression levels.</p> <p><bold>Results.</bold> In the overall cohort, the median PFS reached 5.5 months, with 36-month and 48-month PFS rates of 15.9 % and 9.9 %, respectively. The median OS was 12.0 months; 21.9 % of patients survived 3 years, and 14.3 % of patients remained under observation for five years. In patients transitioning to immuno-oncology treatment after rapid progression following NACT/ACT, the median OS was 17.4 months. The median OS for second-line therapy was two-fold higher than for third-line therapy: 13.9 months <italic>versus</italic> 6.1 months. High treatment efficacy was noted in patients over 70 years of age (median PFS of 8.7 months; median OS of 14.9 months).</p> <p><bold>Conclusion.</bold> In real-world practice, PFS and OS rates were comparable to those reported in registration trials and other real-world evidence studies. The lack of PD-L1 expression testing generally did not affect the efficacy of immuno-oncology therapy in patients with urothelial carcinoma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Десятилетний опыт использования ингибиторов контрольных точек в реальной клинической практике в России позволил провести лечение сотням больных с уротелиальными опухолями. Российское наблюдательное исследование IV фазы AURORA-RU инициировано для оценки эффективности атезолизумаба у больных уротелиальным раком с резистентностью к платиносодержащей химиотерапии. Статья основана на результатах анализа за 2019–2025 гг. и содержит данные по эффективности терапии у российских больных во 2-й и более линиях лекарственной терапии.</p> <p><bold>Цель исследования</bold> – дать оценку клинической эффективности монотерапии атезолизумабом у пациентов с уротелиальным раком верхних и нижних мочевыводящих путей с прогрессированием на фоне платиносодержащей химиотерапии в условиях реальной клинической практики. Первичными конечными точками являлись выживаемость без прогрессирования (ВБП) и общая выживаемость (ОВ). Вторичными конечными точками – подгрупповой анализ эффективности в зависимости от линии терапии, в том числе в подгруппе раннего прогрессирования после неоадъювантной или адъювантной химиотерапии, возрастной когорты, сайтов метастазирования, локализации первичной опухоли (мочевой пузырь, верхние мочевыводящие пути).</p> <p><bold>Материалы и методы.</bold> В исследование включены данные о лечении 152 пациентов (75 % мужчин, 25 % женщин) с верифицированным мышечно-инвазивным местно-распространенным и метастатическим уротелиальным раком, получавших монотерапию ингибитором PD-L1 (лиганд рецептора программируемой клеточной смерти лимфоцитов 1) (атезолизумаб) в 13 центрах России с 2019 по 2025 г. Лечение атезолизумабом проводили у больных с прогрессированием на фоне платиносодержащей химиотерапии. Более половины пациентов (55,9 %) были старше 65 лет. Преобладало число больных (78,3 %) с локализацией первичной опухоли в полости мочевого пузыря. В качестве 2-й линии терапия ингибитором PD-L1 проведена в 57,9 % случаев, и каждый 5-й пациент (21,7 %) получил лечение в 3-й линии. У 86,8 % пациентов лечение проведено без определения уровня экспрессии PD-L1.</p> <p><bold>Результаты.</bold> В общей группе наблюдений медиана ВБП достигла 5,5 мес, 36-месячная ВБП – 15,9 %, 48-месячная ВБП – 9,9 %. Медиана ОВ составила 12,0 мес, 3-летний период пережили 21,9 % больных, в течение 5 лет под наблюдением находились 14,3 % пациентов. При переходе на онкоиммунологическое лечение после быстрой прогрессии на фоне неоадъювантной или адъювантной химиотерапии медиана ОВ составила 17,4 мес. Медиана ОВ для 2-й линии по отношению к 3-й была в 2 раза выше: 13,9 мес против 6,1 мес. Отмечена высокая эффективность терапии у пациентов в возрастной группе старше 70 лет (медиана ВБП 8,7 мес, медиана ОВ 14,9 мес).</p> <p><bold>Заключение.</bold> В реальной практике достигнуты показатели ВБП, ОВ, сопоставимые с таковыми в регистрационном исследовании и исследованиях реальной клинической практики. Отсутствие определения уровня экспрессии PD-L1 в целом не влияло на эффективность онкоиммунологической терапии у пациентов с уротелиальным раком.</p></trans-abstract><kwd-group xml:lang="en"><kwd>urothelial carcinoma</kwd><kwd>atezolizumab</kwd><kwd>survival</kwd><kwd>real-world evidence study</kwd><kwd>phase IV study</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>уротелиальный рак</kwd><kwd>атезолизумаб</kwd><kwd>выживаемость</kwd><kwd>исследование реальной клинической практики</kwd><kwd>исследование IV фазы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Bladder cancer.
