Несмотря на доступность и высокую эффективность современных противоопухолевых препаратов, используемых для терапии больных множественной миеломой (ММ), у большинства пациентов неизбежно развиваются рецидивы заболевания и рефрактерность к проводимой терапии. Прогноз у пациентов с рецидивирующей ММ и рефрактерностью к основным классам используемых противоопухолевых препаратов (ингибиторов протеасом и иммуномодуляторов) остается неблагоприятным, а медиана общей выживаемости (ОВ) составляет только 8 мес. Даратумумаб – первое полностью человеческое моноклональное антитело IgG1-κ, которое с высокой аффинностью связывается с белком CD38 на поверхности миеломных клеток, оказывает прямое воздействие на опухоль, а также обладает иммуномодулирующим механизмом действия. В клинических исследованиях даратумумаб показал высокую эффективность и безопасность при использовании в монорежиме у пациентов с рецидивирующей ММ и двойной рефрактерностью.</p></sec><sec><title>Ц е л ь</title><p>Ц е л ь . Оценить эффективность и безопасность даратумумаба в монорежиме у больных рецидивирующей/рефрактерной множественной миеломой (РРММ) в условиях реальной клинической практики.</p><p>М а т е р и а л ы и м е т о д ы . В исследование были включены 32 пациента с РРММ (14 мужчин и 18 женщин) в возрасте 41–76 лет (медиана – 65 лет), проходивших лечение в двух гематологических центрах г. Новосибирска. У 65.6 % больных была диагностирована IIIА стадия заболевания по Durie-Salmon, I–II стадия по классификации ISS (у 65.6 и 28.1 % больных соответственно) и статус 0–1 по ECOG (у 37.5 и 43.7 % больных соответственно). У 56.3 % пациентов регистрировались оссальные мягкотканные плазмоцитомы, у 12 (37.5 %) отмечалась высокая активность лактатдегидрогеназы. Медиана числа линий предшествующей терапии была равна 2 (диапазон 2–4). Все пациенты ранее получали ингибиторы протеасом (бортезомиб) и противоопухолевые иммуномодуляторы (леналидомид). Аутологичная трансплантация гемопоэтических стволовых клеток была проведена 34.4 % больных. Двойная рефрактерность была зарегистрирована у 24 (75 %) из 32 пациентов. Медиана времени от момента постановки диагноза ММ до начала терапии даратумумабом составила 73.1 мес (диапазон 18–144 мес). Даратумумаб назначали в монорежиме внутривенно в дозе 16 мг/кг еженедельно (циклы 1–2), через неделю (циклы 3–6) и затем ежемесячно.</p></sec><sec><title>Р е з у л ь т а т ы</title><p>Р е з у л ь т а т ы . Средняя продолжительность терапии даратумумабом составила 12.2 мес (диапазон 4–22 мес). Частота общего ответа (полная ремиссия + очень хорошая частичная ремиссия (охЧР) + частичная ремиссия (ЧР)) составила 67.7 %, охЧР – у 9 (29 %) больных, ЧР – у 12 (38.7 %), стабилизация заболевания (СЗ) зарегистрирована у 19.4 % пациентов соответственно. Медиана времени до наступления ответа – 3.5 мес (диапазон 2.5–6). Средняя продолжительность ответа – 7.9 мес (95% доверительный интервал (ДИ) 4.7–11.5). Медиана выживаемости без прогрессирования (ВБП) составила 19.1 мес (95% ДИ 15.3–23.6), а 12- и 18-месячная ВБП были на уровне 91 и 50 % соответственно. Медиана OВ не была достигнута, а значения 12- и 18-месячной ОВ составили 100 и 96.3% соответственно. Глубина ответа оказывала статистически значимое влияние на ВБП (18-месячная ВБП – 100 % в подгруппах охЧР и ЧР и 81 % – в подгруппе СЗ соответственно (χ2 = 19.207, p &lt; 0.001)). Терапия даратумумабом сопровождалась благоприятным профилем токсичности. У 37.5 % пациентов отмечались инфузионные реакции 1-й и 2-й степени тяжести, у 6.2 % ≥ 3-й степени тяжести, у одного пациента терапия была прекращена из-за инфузионной реакции 3-й степени. У 15.6 % пациентов регистрировалась усталость, инфекции верхних и нижних дыхательных путей (15.6 и 12.5 % соответственно), анемия (15.6 %), тромбоцитопения (6.2 %) и нейтропения (6.2 %).</p></sec><sec><title>З а к л ю ч е н и е</title><p>З а к л ю ч е н и е .

Despite the availability and high effectiveness of modern anticancer drugs used to treat patients with multiple myeloma (MM), most patients inevitably develop disease relapses and refractoriness to the ongoing therapy. The prognosis in patients with relapsed MM and refractoriness to the main classes of anticancer drugs (proteasome inhibitors and immunomodulators) remains poor, and the median overall survival (OS) is only 8 months. Daratumumab is the first fully human IgG1-κ monoclonal antibody that binds with high affinity to the CD38 protein on the surface of myeloma cells, has a direct effect on the tumor, and also has an immunomodulatory mechanism of action. In clinical trials, daratumumab has been shown high effective and safety when used as monotherapy in patients with relapsed and double refractory MM.</p></sec><sec><title>A i m</title><p>A i m . To evaluate the effectiveness and safety of daratumumab monotherapy in patients with relapsed/refractory multiple myeloma (RRMM) in real-life clinical practice.</p><p>M a t e r i a l s a n d m e t h o d s . We analyzed 32 patients with RRMM (14 men and 18 women) aged 41–76 years (median 65 years) from two hematological centers in the city of Novosibirsk. In 65.6% of patients, stage IIIA according to Durie-Salmon, stage I–II according to the ISS (in 65.6 and 28.1% of patients, respectively), ECOG performance status 0–1 (in 37.5 and 43.7% of patients, respectively) were diagnosed. Bone-related soft tissue plasmacytomas were recorded in 56.3% of patients, high lactate dehydrogenase activity was noted in 12 (37.5%) patients. The median number of prior lines of therapy was 2 (range 2–4). All patients had previously received proteasome inhibitors (bortezomib) and immunomodulatory agents (lenalidomide). Autologous hematopoietic stem cells transplantation was performed in 34.4% of patients. Double refractory MM was registered in 24 (75%) of 32 patients. The median time from diagnosis of MM to initiation of daratumumab therapy was 73.1 months (range 18–144 months). Daratumumab was administered as monotherapy at a dose of 16 mg/kg intravenously weekly (cycles 1–2), every other week (cycles 3–6), and then monthly.</p></sec><sec><title>R e s u l t s</title><p>R e s u l t s . The median duration of therapy with daratumumab was 12.2 months (range 4–22 months). The overall response rate (complete response + very good partial response (vgPR) + partial response (PR)) was 67.7%; vgPR – in 9 (29%) patients, PR – in 12 (38.7%), stable disease (SD) was registered in 19.4% of patients, respectively. The median time to response was 3.5 months (range 2.5–6). The median duration of response was 7.9 months (95% confidence interval (CI) 4.7–11.5). The median progression-free survival (PFS) was 19.1 months (95% CI 15.3–23.6), and the 12- and 18-month PFS were 91% and 50%, respectively. The median OS was not reached, and the 12- and 18-month OS values were 100% and 96.3%, respectively. The depth of the response had a statistically significant effect on the PFS (18-month PFS was 100% in the vgPR and PR subgroups and 81% in the SD subgroup, respectively (χ2 = 19.207, p &lt; 0.001)). Therapy with daratumumab was accompanied with a favorable toxicity profile. In 37.5% of patients, grade 1 and 2 infusion reactions were noted, in 6.2% grade ≥ 3, in one patient, therapy was discontinued due to an infusion reaction of the 3rd degree. Fatigue, upper and lower respiratory tract infections (15.6% and 12.5%, respectively), anemia (15.6%), thrombocytopenia (6.2%), and neutropenia (6.2%) were recorded in 15.6% of patients.</p></sec><sec><title>C o n c l u s i o n</title><p>C o n c l u s i o n .
