We report the results of IMvigor130, a phase III trial that compared atezolizumab with or without platinum-based chemotherapy versus placebo plus platinum-based chemotherapy in first-line metastatic urothelial carcinoma.</p><p><bold>Materials and methods.</bold> In this multicentre, phase III, randomised trial, untreated patients aged 18 years or older with locally advanced or metastatic urothelial carcinoma, from 221 sites in 35 countries, were randomly assigned to receive atezolizumab plus platinum-based chemotherapy (group A), atezolizumab monotherapy (group B), or placebo plus platinum-based chemotherapy (group C). Patients received 21-day cycles of gemcitabine (1000 mg/ml body surface area, administered intravenously on days 1 and 8 of each cycle), plus either carbo-platin (area under the curve of 4.5 mg/mL per min administered intravenously) or cisplatin (70 mg/ml body surface area administered intravenously) on day 1 of each cycle with either atezolizumab (1200 mg administered intravenously on day 1 of each cycle) or placebo. Group B patients received 1200 mg atezolizumab, administered intravenously on day 1 of each 21-day cycle. The co-primary efficacy endpoints for the intention-to-treat population were investigator-assessed Response Evaluation Criteria in Solid Tumours 1.1 progression-free survival (PFS) and overall survival (OS) (group A vs group C) and OS (group B vs group C), which was to be formally tested only if OS was positive for group A versus group C. The trial is registered with ClinicalTrials.gov, NCT02807636.</p><p><bold>Results. </bold>Between July 15, 2016, and July 20, 2018, were enrolled 1213patients. 451 (37 %) were randomly assigned to group A, 362 (30 %) to group B, and 400 (33 %) to group C. Median follow-up for survival was 11.8 months (interquartile range 6.1—17.2 months) for all patients. At the time of final PFS analysis and interim OS analysis (May 31, 2019), median PFS in the intention-to-treat population was 8.2 months (95 % confidence interval (CI) 6.5—8.3) in group A and 6.3 months (95 % CI 6.2—7.0) in group C (stratified hazard ratio 0.82; 95 % CI 0.70—0.96; one-sided p = 0.007). Median OS was 16.0 months (95 % CI 13.9—18.9) in group A and 13.4 months (95 % CI 12,0—15.2) in group C (0.83; 95 % CI 0.69—1.00; one-sided p =0.027). Median OS was 15.7 months (95 % CI 13.1—17.8) for group B and 13.1 months (95 % CI 11.7—15.1) for group C (1.02; 95 % CI 0.83—1.24). Adverse events that led to withdrawal of any agent occurred in 156 (34 %) patients in group A, 22 (6 %) patients in group B, and 132 (34 %) patients in group C. 50 (11 %) patients in group A, 21 (6 %) patients in group B, and 27 (7 %) patients in group C had adverse events that led to discontinuation of atezolizumab or placebo.</p><p><bold>Conclusion</bold>. Addition of atezolizumab to platinum-based chemotherapy as first-line treatment prolonged PFS in patients with metastatic urothelial carcinoma. The safety profile of the combination was consistent with that observed with the individual agents. These results support the use of atezolizumab plus platinumbased chemotherapy as a potentialfirst-line treatment option for metastatic urothelial carcinoma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Ингибитор PD-L1 атезолизумаб показал эффективность в лечении распространенных форм уротелиального рака как в 1-й линии при невозможности назначения цисплатина (при наличии экспрессии PD-L1 &gt;5 % на иммунокомпетентных клетках) и любой платиносодержащей химиотерапии (независимо от экспрессии PD-L1), так и при прогрессировании заболевания на фоне химиотерапии, а также у пациентов с быстрым прогрессированием заболевания в течение 12 мес после неоадъювантной или адъювантной химиотерапии. В статье приведены результаты исследования III фазы IMvigor130, в котором сравнивали комбинацию атезолизумаба и химиотерапии на основе платины с химиотерапией и с монотерапией атезолизумабом в 1-й линии лечения больных распространенным уротелиальным раком.</p><p><bold>Материалы и методы</bold>. В рамках многоцентрового рандомизированного исследования IIIфазы, в котором принял участие 221 центр в 35 странах, ранее не леченным пациентам в возрасте 18 лет и старше с местно-распространенным или метастатическим уротелиальным раком были случайным образом назначены атезолизумаб + химиотерапия на основе платины (группа А), атезолизумаб в монотерапии (группа B), плацебо + химиотерапия на основе платины (группа C). Пациенты получали 21-дневные циклы гемцитабина (1000 мг/м<sup>2</sup> площади поверхности тела, внутривенно в 1-й и 8-й дни каждого цикла) + либо карбоплатин (площадь под кривой 4,5 мг/мл/мин, внутривенно), либо цисплатин (70 мг/м<sup>2</sup>, внутривенно) в 1-й день каждого цикла с атезолизумабом (1200 мг, внутривенно, в 1-й день каждого цикла) или с плацебо. Пациенты группы В получали 1200 мг атезолизумаба, вводимого внутривенно в 1-й день каждого 21-дневного цикла. Первичными конечными точками эффективности лечения были оцененные непосредственно исследователями согласно критериям оценки ответа солидных опухолей версии 1.1 (RECIST 1.1) выживаемость без прогрессирования (ВБП) и общая выживаемость (ОВ) (группа A против группы C), а также ОВ (группа B против группы C) с необходимостью проверки в центральной лаборатории, если ОВ была выше в группе А, чем в группе С. Испытание зарегистрировано на ресурсе ClinicalTrials.gov — NCT02807636.</p><p><bold>Результаты.</bold> В период с 15 июля 2016 г. по 20 июля 2018 г. в исследование были включены 1213 пациентов. Случайным образом 451 (37 %) пациент распределен в группу A, 362 (30 %) — в группу B, 400 (33 %) — в группу C. Медиана наблюдения составила 11,8 мес (интерквартильный размах 6,1—17,2) для всех больных. Во время окончательного анализа ВБП и промежуточного анализа ОВ (31 мая 2019 г.) медиана ВБП в популяции больных, продолжающих лечение, составила 8,2 мес (95 % доверительный интервал (ДИ) 6,5—8,3) в группе А и 6,3 мес (95 % ДИ 6,2—7,0) в группе С (стратифицированное отношение рисков 0,82; 95 % ДИ 0,70—0,96; р = 0,007). Медиана ОВ составила 16,0 мес (95 % ДИ 13,9—18,9) в группе A и 13,4 мес (95 % ДИ 12,0—15,2) в группе C (0,03; 95 % ДИ 0,69—1,00; р = 0,027). Медиана ОВ составила 15,7 мес (95 % ДИ 13,1—17,8) в группе B и 13,1 мес (95 % ДИ 11,7—15,1) в группе C (1,02; 95 % ДИ 0,83—1,24). Нежелательные явления, которые привели к отмене какого-либо из препаратов, зарегистрированы у 156 (34 %) пациентов в группе A, у 22 (6 %) в группе B, у 132 (34 %) в группе C. Нежелательные явления, которые привели к прекращению приема атезолизумаба или плацебо, наблюдались у 50 (11 %) пациентов в группе A, у 21 (6 %) в группе B, у 27 (7 %) в группе C.</p><p><bold>Заключение.</bold> Добавление атезолизумаба к химиотерапии на основе платины в качестве терапии распространенного уротелиального рака в 1-й линии увеличивает ВБП пациентов с метастатическим уротелиальным раком. Профиль безопасности комбинации соответствовал описанному ранее для отдельных препаратов. Полученные результаты демонстрируют возможность применения атезолизумаба в комбинации с платиносодержащей химиотерапией в качестве перспективного варианта лечения пациентов с распространенным уротелиальным раком в 1-й линии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>urothelial carcinoma</kwd><kwd>checkpoint inhibitors</kwd><kwd>chemotherapy</kwd><kwd>atezolizumab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>уротелиальный рак</kwd><kwd>ингибиторы иммунных контрольных точек</kwd><kwd>химиотерапия</kwd><kwd>атезолизумаб</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed without external funding</funding-statement><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
