Аннотация

   В работе представлен новый протокол терапии пациентов с BRAF-позитивным гистиоцитозом из клеток Лангерганса (ГКЛ). В целях достижения ремиссии использовалась комбинация вемурафениба (таргетный препарат) и цитарабина (Ara-С) с кладрибином (2-CdA). В исследование вошли 27 пациентов, у 18 из них была установлена мультисистемная форма ГКЛ с поражением органов риска (RO+), у 9 – мультисистемная форма без вовлечения органов риска (RO–). Терапия начиналась с 28-дневного приема вемурафениба, после чего он отменялся. На 29-е сутки начинался блок полихимиотерапии Аra-C + 2-СdA № 1. Прием вемурафениба возобновлялся на +1-е сутки после блока Ara-C + 2-CdA. Интервал между блоками – 28 дней. В таком же режиме проводились последующие 2 блока химиотерапии Аra-C + 2-СdA – № 2 и № 3. Затем прием вемурафениба прекращался, после чего следовали 3 курса 2-CdA в монорежиме. У всех пациентов наблюдался быстрый ответ на проводимую терапию: на 28-е сутки значение по шкале активности заболевания снизилось с 15 до 2 баллов в группе RO+ и с 4 до 0 баллов в группе RO–. Двухлетняя безрецидивная выживаемость в группе RO+ составила 82 % (95 % доверительный интервал 66–100), в группе RO– она достигла 89 % (95 %, доверительный интервал 71–100). Общая выживаемость в обеих группах составила 100 %. Данное исследование демонстрирует, что комбинация вемурафениба и промежуточных доз 2-CdA и Ara-C безопасна и эффективна у детей с мультисистемной формой RO+ и рефрактерных ГКЛ. Данное проспективное многоцентровое нерандомизированное исследование было одобрено независимым этическим комитетом (протокол №3e/1-18) и утверждено решением
ученого совета НМИЦ ДГОИ им. Дмитрия Рогачева. Исследование зарегистрировано на сайте Clinicaltrials.gov, номер NCT03585686. Первый пациент был включен в исследование 22. 06. 2018, дата окончания сбора данных – 30. 04. 2023.

Abstract

   Here, we report on a new treatment protocol for patients with BRAF-positive Langerhans cell histiocytosis (LCH). To achieve remission in the affected patients, we used vemurafenib (a targeted drug) in combination with cytarabine (Ara-C) and cladribine (2-CdA). The study included 27 patients: 18 children with multisystem LCH with risk organ involvement (RO+) and 9 – with multisystem LCH without risk organ involvement (RO–). The treatment started with a 28-day cycle of vemurafenib, with subsequent discontinuation. On Day 29, Аra-C + 2-СdA chemotherapy cycle № 1 was initiated. Vemurafenib treatment was again started on Day +1 after the Ara-C + 2-CdA cycle. The interval between the cycles was 28 days. Similarly, the next two Аra-C + 2-СdA chemotherapy cycles (№ 2 and № 3) were carried out. Then therapy with vemurafenib was stopped and 3 cycles of 2-CdA were administered. All the patients responded to the treatment quickly: on Day 28, disease activity score decreased from 15 to 2 in the RO+ group and from 4 to 0 in the RO– group. The two-year relapse-free survival in the RO+ group was 82 % (95 % confidence interval 66–100), and 89 % (95 % confidence interval 71–100) in the RO– patients. The overall survival in both groups was 100 %. Our study demonstrates the safety and effectiveness of the treatment with vemurafenib and intermediate-dose 2-CdA and Ara-C in children with multisystem RO+ and refractory LCH. This prospective non-randomized multicenter study was approved by the Independent Ethics Committee (Minutes No. 3e/1-18) and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology of Ministry of Healthcare of the Russian Federation. It is registered at clinicaltrials.gov under the number NCT03585686. The first patient was enrolled on 22 June 2018, the data collection was stopped on 30 April 2023.
