Definitions
- the present invention relates to a therapeutic agent for anti-CCR4 antibody-resistant cancer containing the compound represented by the formula (I) or a pharmaceutically acceptable salt thereof as an active ingredient, and in particular, treating mogamulizumab-resistant cancer.
- a therapeutic agent for anti-CCR4 antibody-resistant cancer containing the compound represented by the formula (I) or a pharmaceutically acceptable salt thereof as an active ingredient, and in particular, treating mogamulizumab-resistant cancer.
- Non-Patent Document 3 the prognosis is still the lowest among malignant lymphomas
- Non-Patent Document 4 the treatment result of anti-CCR4 antibody for recurrent cases is 13.7 months (Non-Patent Document 5). Therefore, there is an urgent need to prevent viral infections, prevent the onset of leukemia, and develop new therapeutic methods based on the elucidation of pathological conditions at the molecular level.
- Non-Patent Document 6 From the results of a large-scale analysis of gene expression using a large number of ATL clinical specimens, it was clarified that ATL cells are a population having a very uniform and abnormal gene expression pattern (Non-Patent Document 6). Furthermore, it has become clear that ATL cells have characteristic signal transduction system abnormalities and are the basis of tumor cell survival and proliferation, but the background is the accumulation of epigenetic abnormalities (" Non-Patent Document 7).
- Enhancer of zeste homologue 1/2 (EZH1 / 2) is the active center of Polycomb repressive complex 2 (PRC2) that trimethylates histone H3K27.
- PRC2 Polycomb repressive complex 2
- EZH1 and EZH2 compensate each other for their functions and maintain the intracellular epigenome. Inhibition of EZH2 leads to a decrease in the methylation level of H3K27 throughout the cell, but the compensatory effect of EZH1 limits the effect. By simultaneously inhibiting EZH1 and EZH2, methylation can be eliminated more effectively (Non-Patent Document 8).
- Non-Patent Documents 9 and 10 It has been shown that abnormalities in PRC2 constituents lead to abnormalities in cancer and stem cell function, and in particular, accumulation of methylated H3K27me3 induced by genetic abnormalities and upregulation of EZH2 has been identified in many cancers, and EZH2 Is being energetically studied as a new molecular target for cancer.
- Non-Patent Documents 6 and 11 Abnormalities of the Polycomb family in ATL were clarified by comprehensive gene expression analysis. Among them, overexpression of EZH2 is remarkable, and an increase in the methylation level of H3K27 in the whole cell is also detected. It has also been clarified that EZH2-dependent inhibition of miR-31 results in the expression of NF- ⁇ B inducing kinase (NIK) and constitutively activates the NF- ⁇ B pathway, and that EZH2 is an ATL molecule. It is considered to be an effective target.
- NIK NF- ⁇ B inducing kinase

本治験は、再発又は難治性(標準治療法がない、又は標準的治療法に不応もしくは不耐)の非ホジキンリンパ腫患者(ATL患者を含む)を対象に臨床化合物を投与した際の安全性、忍容性、薬物動態、および抗腫瘍効果等を検討することを目的とした、多施設共同非盲検第I相試験である。選択基準を満たし、除外基準に該当しない被験者に対して低用量から臨床化合物を反復投与し、忍容性が確認できれば次のコホートの用量を漸増し、本治験の中で用量制限毒性および次相推奨用量を決定する。
臨床化合物は、各被験者へ1日1回連日経口投与し、忍容不能な毒性が発現する、または疾患進行を認めるまで投与を継続した。個々の被験者は、臨床化合物の最終投与日から30日後、または他の抗がん剤治療を開始する、どちらか早い日まで観察し安全性を評価した。抗腫瘍効果は原則8週間間隔で実施し、Definition, prognostic factors, treatment, and response criteria of adult T-cell leukemia-lymphoma: a proposal from an international consensus meeting” (J Clin Oncol. 2009;27[3]:453-9)に基づき評価した。
最初のコホートの用量は非臨床試験の結果を元に、150 mg 1日1回とした。次コホートの用量は、用量制限毒性発現の有無の情報を元に修正版連続再評価法(modified continual reassessment method: mCRM)で推奨される用量、並びにその時点までに得られているすべての安全性(用量制限毒性以外の有害事象および臨床検査値異常を含む)、薬物動態、バイオマーカー、および有効性の情報を総合的に評価して、治験依頼者と治験責任医師、外部専門家と協議し決定した。

Blood. 2015;126(24):2570-7)、本臨床化合物は新たな治療選択肢になり得ると考えられた。結果を表1に示す。
モガムリズマブ投与歴がある再発又は難治性のATL患者、あるいはモガムリズマブ不耐・適応外で1 レジメン以上の全身化学療法を施行した後の再発又は難治性のATL患者
臨床化合物の投与量は、これまでに得られたデータに基づき最も適切と考えられた投与量を選択し、試験計画書などに明記する。臨床化合物は用量の異なる2種類の錠剤を組み合わせて提供する。投与方法は1日1回連日経口投与する。
ATLに対する治療効果判定は、Definition, prognostic factors, treatment, and response criteria of adult T-cell leukemia-lymphoma: a proposal from an international consensus meeting” (J Clin Oncol. 2009;27[3]:453-9)に基づき実施する。治療開始前に、被験者の病態に応じて、CTスキャン、骨髄検査、内視鏡検査、血液検査のうち必要な検査を実施し標的病変を定め、病変の変化を診断する。主治医の判定に加え、社外に判定委員会を設置し、独立且つ統一した判定を実施する。
例えば、奏効率(完全寛解[complete remission: CR]率、不確定完全寛解[uncertified complete remission: CRu]率、及び部分寛解[partial remission: PR]率の合計)、奏効期間、無増悪生存期間(progression-free survival: PFS)、及び全生存期間(overall survival: OS)を副次評価項目に設定し、有効性を探索的に評価する。
