По результатам исследований III фазы NETTER-1 и NETTER-2 терапия 177Lu‑DOTA‑TATE стала стандартом второй и последующей линий терапии, однако отечественных работ, посвященных изучению ПРРТ, на сегодняшний день нет. В нашем исследовании мы оценили эффективность и безопасность терапии пациентов с нейроэндокринными неоплазиями (НˑН) радиофармацевтическим лекарственным препаратом (РФЛП) 177Lu‑DO‑TA‑TATE, синтезированным в циклотронно-радиохимической лаборатории отдела радионуклидной диагностики и терапии НМИЦ онкологии им. Н.Н. Блохина и прошедшим доклинические испытания.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: В данное исследование I/II фазы включены пациенты с метастатическими НЭН различных локализаций с Ki67&lt;55 %, прогрессирующими на фоне ≥2 предшествующих линий терапии. В рамках исследования пациенты получали 4 цикла ПРРТ РФЛП 177Lu‑DOTA‑TATE активностью по 6,5 ± 1 ГБк каждые 8–10 недель на фоне терапии пролонгированными формами аналогов соматостатина. Первичными конечными точками являлись частота ответа в виде контроля над заболеванием ≥ 6 месяцев и безопасность терапии. Вторичными конечными точками стали частота объективного ответа, выживаемость без прогрессирования (ВБП) и общая выживаемость (ОВ). Набор пациентов осуществлялся в период с июня 2024 г. по июль 2025 г. В данной работе проведен анализ первых 11 пациентов, включенных в исследование.</p></sec><sec><title>Результаты</title><p>Результаты: В настоящий анализ включено 11 пациентов. Средний возраст составил 54 года. Локализации первичной опухоли: гастроэнтеропанкреатические (ГЭП) НЭН — 6 (54,5 %), феохромоцитомы/параганглиомы — 3 (27,3 %), НЭН легких и метастазы НЭН из НПО по 1 пациенту (9,3 %). Медиана Ki67 составила 10 % (5–25 %). Все пациенты ранее получали терапию эверолимусом, 9 (81,8 %) пациентов — химиотерапию. Частота объективного ответа (ЧОО) составила 54,5 %, все ответы были частичные. Стабилизация заболевания (СЗ) была зарегистрирована в 36,4 %. Контроль заболевания (КЗ) ≥ 6 месяцев отмечен в 90,9 % случаев. Медиана ВБП и ОВ при медиане наблюдения 11,3 месяца не достигнуты. Лейкопения 3–4 степени была зарегистрирована у 2 пациентов (18,2 %). Снижение почечной функции отмечено не было. Зарегистрировано 1 серьезное нежелательное явление, связанное с прогрессированием заболевания — плеврит, потребовавший плевроцентеза для эвакуации жидкости.</p></sec><sec><title>Заключение</title><p>Заключение: Пептид-рецепторная радионуклидная терапия РФЛП 177Lu‑DOTA‑TATE, произведенным в НМИЦ онкологии им.

Клинически значимая миелосупрессия была отмечена в 18,2 % случаев.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Peptide-receptor radionuclide therapy (PRRT) is currently a well-studied treatment option for patients with neuroendocrine tumors. Based on the results of the Phase III NETTER-1 and NETTER-2 trials, 177Lu-DOTA-TATE therapy has become the standard for second- and subsequent-line therapy. However, there are currently no domestic studies investigating PRRT. In our study, we evaluated the efficacy and safety of 177Lu-DOTA-TATE, a radiopharmaceutical drug synthesized in the cyclotron-radiochemistry laboratory of the Department of Radionuclide Diagnostics and Therapy at the N.N. Blokhin National Medical Research Center of Oncology and having undergone preclinical trials, in patients with neuroendocrine neoplasias (NENs).</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods: This phase I/II study enrolled patients with metastatic NENs of various locations with Ki-67 &lt;55 %, progressing despite ≥​​ 2 prior lines of therapy. Patients received 4 cycles of PRRT with the 177Lu-DOTA-TATE radiopharmaceutical every 8–10 weeks, along with extended-release somatostatin analogs. The primary endpoints were response rate (disease control) of ≥​​ 6 months and safety. Secondary endpoints were objective response rate, progression-free survival (PFS), and overall survival (OS). Patients were enrolled from June 2024 to July 2025. This study analyzes the Įrst 11 patients enrolled in the study.</p></sec><sec><title>Results</title><p>Results: Eleven patients were included in this analysis. The median age was 54 years. Primary tumor localizations: gastroenteropan‑ creatic (GEP) NEN — 6 patients (54.5 %), pheochromocytomas/paragangliomas — 3 patients (27.3 %), lung NEN and NEN metastases from the esophagus — 1 patient each (9.3 %). Median Ki-67 was 10 % (5–25 %). All patients had previously received everolimus therapy, 9 patients (81.8 %) — chemotherapy. The objective response rate (ORR) was 54.5 %, all responses were partial. Disease stabilization (DS) was recorded in 36.4 %. Disease control (DC) ≥​​ 6 months was noted in 90.9 % of cases. Median PFS and OS with a median follow-up of 11.3 months were not achieved. Grade 3–4 leukopenia was recorded in 2 patients (18.2 %). No decrease in renal function was noted. One serious adverse event associated with disease progression was recorded: pleurisy, requiring thoracentesis for fluid evacuation.</p></sec><sec><title>Conclusion</title><p>Conclusion: Peptide-receptor radionuclide therapy with 177Lu-DOTA-TATE, manufactured at the Blokhin National Medical Research Center of Oncology, resulted in high ORR and CFS rates in patients with NEN of various locations. Clinically signiĮcant myelosuppres‑ sion was observed in 18.2 % of cases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейроэндокринные неоплазии</kwd><kwd>пептид-рецепторная радионуклидная терапия</kwd><kwd>радиофармацевтические лекарственные препараты</kwd><kwd>177Lu-DOTA-TATE</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neuroendocrine neoplasia</kwd><kwd>peptide-receptor radionuclide therapy</kwd><kwd>radiopharmaceuticals</kwd><kwd>177Lu-DOTA-TATE</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study had no sponsorship.</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">Weber WA, Barthel H, Bengel F, et al.
