Description
[2]前記抗体医薬は、免疫チェックポイント阻害を介してがんの増殖を抑制する作用効果を有するものである、上記[1]記載の抗体医薬の効果増強用組成物。
[3]前記抗体医薬は、PD-L1に対するモノクローナル抗体を含むものである、上記[1]記載の抗体医薬の効果増強用組成物。
[4]前記抗体医薬は、メラノーマの増殖を抑制する作用効果を有するものである、上記[1]記載の抗体医薬の効果増強用組成物。
アウレオバシジウム プルランス M-2(Aureobasidium pullulans M-2、独立行政法人製品評価技術基盤機構 特許生物寄託センター受託番号:FERM BP-10014)を液体培地に植菌し、24.5℃で4日間振とう培養することで、培養液中にβ-グルカンを産生させた。β-グルカン濃度はフェノール硫酸法および酵素法によっておよそ6mg/mLと見積られた。
常法に従い、腫瘍細胞株の移植による担がんマウスを作成し、被験物質の投与によってその腫瘍の成長に影響があるかどうかを調べた。
腫瘍細胞移植後16日目の担がんマウスを解剖し、それぞれの試験群の担がんマウスから脾臓リンパ球及び腫瘍浸潤リンパ球(TIL)を分離・精製した。リンパ球は、採取した組織を滅菌蒸留水にて溶血した後、リンパ球分離キット(商品名「lympholyte-M」、(Cedarlane Laboratories社)にて調製した。
試験例1と同様にして、腫瘍細胞株の移植による担がんマウスを作成し、被験物質の投与によってその腫瘍の成長に影響があるかどうかを調べた。その際、被験物質として、アウレオバシジウム プルランス由来のβ-グルカンに替えて、シイタケ由来のβ-グルカン(「ミセルグルカン」、株式会社 RL-JP製)(以下、「ミセルβ-グルカン」という。)を用いた。
Claims (4)
- アウレオバシジウム プルランスの培養物由来のβ-グルカンを有効成分として含有し、免疫チェックポイント阻害を介してがんの増殖を抑制する作用効果を有する抗体医薬とともに投与されるものであることを特徴とする抗体医薬の効果増強用組成物。
- 前記抗体医薬は、PD-L1に対するモノクローナル抗体を含むものである、請求項1記載の抗体医薬の効果増強用組成物。
- 前記抗体医薬は、メラノーマの増殖を抑制する作用効果を有するものである、請求項1記載の抗体医薬の効果増強用組成物。
- 腹腔内投与用である、請求項1記載の抗体医薬の効果増強用組成物。
