Description

高リスク骨髄線維症の治療剤Treatment for high-risk myelofibrosis
 本発明は、一般式[1]:
[式中、R、R、R、R、R、Xは、本明細書に記載の通りである]
で表される化合物又はその医薬上許容される塩を有効成分として含有する新規な高リスク骨髄線維症の治療剤に関するものである。
The present invention is based on the general formula [1]:
[wherein R 1 , R 2 , R 3 , R 4 , R 5 , and X are as described herein]
The present invention relates to a novel therapeutic agent for high-risk myelofibrosis, which contains the compound represented by or a pharmaceutically acceptable salt thereof as an active ingredient.
 骨髄線維症は、広範な骨髄の線維化としばしば髄外造血(主に脾臓)を伴う疾患であり、原発性であるか、悪性および良性の血液疾患に続発する。骨髄線維症は、貧血、脾腫の症状のほか、後期において全身倦怠感,体重減少、発熱、または脾梗塞の症状がみられる患者もいる(非特許文献1)。 Myelofibrosis is a disease with extensive bone marrow fibrosis and often extramedullary hematopoiesis (mainly in the spleen), which can be primary or secondary to malignant and benign hematological disorders. In myelofibrosis, in addition to symptoms of anemia and splenomegaly, some patients exhibit symptoms of general malaise, weight loss, fever, or splenic infarction in the later stages (Non-Patent Document 1).
 骨髄異形成症候群に対する国際予後スコアリングシステム(International Prognostic Scoring System:IPSS)は、初発の原発性骨髄線維症に使用されており、骨髄異形成症候群に対する動的国際予後スコアリングシステム(Dynamic International Prognostic Scoring System;DIPSS)は、慢性骨髄性白血病への進行を予測するために使用できる(非特許文献1)。 The International Prognostic Scoring System (IPSS) for myelodysplastic syndromes is used for newly diagnosed primary myelofibrosis, and the Dynamic International Prognostic Scoring System (IPSS) for myelodysplastic syndromes (IPSS) is used for newly diagnosed primary myelofibrosis. nostic Scoring System; DIPSS) can be used to predict progression to chronic myeloid leukemia (Non-Patent Document 1).
 また、DIPSSに、血小板数 100,000/μL以下、予後不良染色体、輸血依存を加味したDIPSS-plusが提唱されている(非特許文献2)。 Furthermore, DIPSS-plus has been proposed, which takes into account platelet count of 100,000/μL or less, chromosomes with poor prognosis, and blood transfusion dependence to DIPSS (Non-Patent Document 2).
 骨髄線維症は、国際予後スコアリングシステムに基づいて、低リスク、中間-1リスク、中間-2リスク、高リスクに分類される。 Myelofibrosis is classified into low risk, intermediate-1 risk, intermediate-2 risk, and high risk based on the International Prognostic Scoring System.
 現在、進行した原発性骨髄線維症に対し、非特異的にJAK経路を阻害するルキソリチニブが第1選択の治療法である。ルキソリチニブの主な有害作用は貧血と血小板減少である(非特許文献1)。 Currently, ruxolitinib, which nonspecifically inhibits the JAK pathway, is the first-line treatment for advanced primary myelofibrosis. The main adverse effects of ruxolitinib are anemia and thrombocytopenia (Non-Patent Document 1).
 ルキソリチニブは、JAK1/2阻害薬である。ルキソリチニブは、中間リスクまたは高リスクの原発性または続発性(真性多血症後または本態性血小板血症後)の骨髄線維症(MF)の成人患者の治療に使用されるが、ベースライン血小板数が50,000/μL以上の患者にのみ使用される(非特許文献3)。 Ruxolitinib is a JAK1/2 inhibitor. Ruxolitinib is used to treat adult patients with intermediate-risk or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis (MF), with baseline platelet count It is used only for patients with 50,000/μL or more (Non-Patent Document 3).
 フェドラチニブは、JAK2選択的阻害薬である。フェドラチニブは、中間リスクまたは高リスクの原発性または続発性(真性多血症後または本態性血小板血症後)の骨髄線維症(MF)の成人患者の治療に使用されるが、ベースライン血小板数が50,000/μL以上の患者にのみ使用される(非特許文献4)。 Fedratinib is a JAK2 selective inhibitor. Fedratinib is used to treat adult patients with intermediate- or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis (MF), but the baseline platelet count It is used only for patients with 50,000/μL or more (Non-Patent Document 4).
 前記一般式[1]で示される化合物は、JAK2選択的阻害薬であることが報告されている(特許文献1~3)。しかしながら、一般式[1]で示される化合物が、高リスク骨髄線維症の治療に有用であることはこれまでに報告されていない。 It has been reported that the compound represented by the general formula [1] is a JAK2 selective inhibitor (Patent Documents 1 to 3). However, it has not been reported to date that the compound represented by general formula [1] is useful for treating high-risk myelofibrosis.
