Аннотация

Для лечения метастатических гастроинтестинальных стромальных опухолей (ГИСО) применяются три препарата: иматиниб, сунитиниб и регорафениб. В январе 2020 г. появился еще один препарат – авапритиниб (BLU-285, Ayvakit). Авапритиниб – новый селективный тирозинкиназный ингибитор, блокирующий PDGFRA и KIT-мутации. На основании исследования NAVIGATOR авапритиниб одобрен FDA для лечения ГИСО с мутациями в экзоне 18, в том числе при мутации D842V. Авапритиниб включен в рекомендации NCCN в 1-ю линию при мутации D842V. По данным литературы описаны лишь единичные случаи эффекта при мутации D842V при применении иматиниба и регорафениба. Авапритиниб – первый препарат, обладающий высокой противоопухолевой активностью при мутации D842V. Авапритиниб высокоэффективен и при вторичных мутациях, что объясняет его активность в ≥4 линиях лечения. В нашей статье мы приводим результаты исследования NAVIGATOR и клиническое наблюдение применения авапритиниба у пациента с метастатической ГИСО в 6-й линии лечения. На фоне терапии достигнута частичная регрессия, длительность которой составила 9 мес. Самыми ранними побочными эффектами были периорбитальные отеки и повышенное слезотечение. Через 3 мес отмечена гематологическая токсичность, что потребовало коррекции дозы авапритиниба.

Ключевые слова: гастроинтестинальные стромальные опухоли, PDGFRA, авапритиниб, BLU-285, Айвакит.

________________________________________________

We have three drugs for treatment of gastrointestinal stromal tumors (GIST): imatinib, sunitinib and regorafenib. Avapritinib (Ayvakit, BLU-285) is one more drug that was approved in January 2020. Avapritinib is a new selective tyrosine kinase inhibitor of PDGFRA and KIT mutations. Based on NAVIGATOR trial avapritinib was approved by FDA for treatment of PDGFRA exon 18 mutant GIST including D842V. Avapritinib was included in NCCN guidelines in the first line therapy PDGFRA D842V mutant GIST. There are only several cases describe imatinib and regorafenib efficacy in D842V mutation in the literature. Avapritinib is the first drug with high efficacy in D842V mutant GIST. Avapritinib has high efficacy against second mutations that explain its activity in ≥4 lines of treatment. This article summarizes the results of NAVIGATOR trial and describes a clinical case of the patient with advanced GIST who received avapritinib in 6th line of treatment. Partial response was achieved that lasted 9 months. The earliest side effects were periorbital edema and increased lacrimation. Three months later the dose of аvapritinib was reduced because of hematological toxicity.

Key words: gastrointestinal stromal tumors, PDGFRA, avapritinib, BLU-285, Ayvakit.
