Definitions
- the present invention relates to a drug (hereinafter, may be abbreviated as "STING agonist”) containing an STING agonist compound prescribed in suppressing cancer progression, suppressing recurrence and / or treating it as an active ingredient.
- STING agonist a drug containing an STING agonist compound prescribed in suppressing cancer progression, suppressing recurrence and / or treating it as an active ingredient.
- STING Stimulation of Interferon Genes
- cGAS cyclic GMP-AMP synthase
- cGAMP cyclic GMP-AMP
- cyclic dinucleotides such as cyclic Di-GMP, which was first identified as a second messenger of bacteria and later confirmed to exist in mammals, also directly binds to STING and activates it (non-patent literature). 1).
- STING is also known to be involved in autoimmune diseases and tumor immunity.
- abnormal host DNA has been shown to leak from the nucleus, activating STING and inducing an pro-inflammatory response, indicating its involvement in autoimmune diseases.
- the STING pathway also detects tumor-derived DNA and promotes T cell responses to tumors.
- the STING-agonizing compound administered to a mouse tumor induces an acquired immune response to cause tumor regression (Non-Patent Document 2), and an activating molecule of the STING pathway enhances IFN production and exhibits an antiviral effect. (Non-Patent Document 3) is known.
- An object of the present invention is to provide a formulation that avoids induction of inflammatory cytokine production caused by a STING agonist.
- the present inventors have diligently studied the formulation of a STING agonist in order to find a formulation that can solve the above problems, and found that it is administered in combination with a corticosteroid. Furthermore, by administering a reduced dose of STING agonist in combination with an antineoplastic agent that is not concerned about the development of cytokine release syndrome, and further in combination with a corticosteroid, there is a greater concern about cytokine release syndrome. A reduced formulation was found and the present invention was completed.

その後、腫瘍体積の変化を継時的に移植30日後(Day30)まで各々測定した。なお、腫瘍体積は実施例17で示した式より算出した。その結果を図9および10に各々示す。
化合物Aは、上記投与量において、抗PD-1抗体および抗VEGFR2抗体の抗腫瘍効果を各々増強した。
実施例3において製造した化合物(化合物B)について、図13の表中に示す複数のヒト急性骨髄性白血病細胞株に対する抗腫瘍作用を評価した。
上記細胞株を培地(10%FBSおよび1% Penicillin-Streptomycin含有RPMI1640)に各々懸濁し、5.0×104細胞/ウェルの密度で96ウェルプレートに播種した。播種直後に、化合物BおよびVehicle(培地中添加後終濃度0.1%DMSO溶液)を各々含む培地を各ウェルに添加し、よく混和した。なお、化合物Bは、培地中添加後の終濃度が各々100~1000 nmol/Lになるように調製した。37℃、5% CO2条件下にて48時間当該細胞株を培養した後、各ウェルにCell Counting Kit-8(Dojindo)を10μL添加し、続いて60分の培養後、マイクロプレートリーダーで各wellにおける吸光度(450nm)を測定した。Graphpad prism(Graphpad Software社)を用いて当該吸光度値からからEC50値を算出し、化合物Bによる細胞増殖への影響を評価した。その結果を図11に示す。また、Relative cell countを以下の式に従って算出した。Relative minimum cell countは上述値の最小値を表す。
ヒト急性骨髄性白血病細胞株MV4-11を、免疫不全マウス(C.B-17/Icr-scid/scidJcl、雌、6週齢(日本クレア社))の右側腹部に皮下移植し(ここで、移植日をDay0とした。)、MV4-11皮下担癌マウスを作製した。移植6日後に、腫瘍体積に基づき群分けし、当該皮下担癌マウスに対して、化合物A(各々0.3、1.0および3.0 mg/kg;n=8)およびVehicle(n=8)を各々投与した。腫瘍体積の変化を継時的に移植28日後(Day28)まで測定した。腫瘍体積は実施例17で示した式より算出した。その結果を図12に示す。
化合物Aは、投与量1.0 mg/kgおよび3.0 mg/kgにおいて腫瘍増殖を抑制した。本実施例には免疫不全マウスを用いていることから、化合物Aは腫瘍免疫を介さず、直接的な作用でがん細胞の増殖を抑制したことを示している。
本発明にかかるSTING作動化合物および抗悪性腫瘍剤との併用について、以下の複数のヒト急性骨髄性白血病細胞株(KG-1α、THP-1およびCMK)およびヒトB細胞リンパ腫細胞株(DOHH2およびOLI-Ly3)に対する抗腫瘍作用を評価した。
上記各細胞株を培地(10% FBSおよび1% Penicillin-Streptomycin含有RPMI1640)に各々懸濁し、2.5~5×104細胞/ウェルの密度で96ウェルプレートに播種した。播種直後に、培地中添加後の終濃度が0、10、30、100、300および1000 nmol/Lとなるよう各々調製した化合物Bおよび以下の各終濃度となるよう各々調製した抗悪性腫瘍剤の2剤を各々含む培地を各ウェルに添加し、よく混和した。なお、コントロールとして、培地中添加後の終濃度が0.1%となるよう調製したDMSO溶液を別途添加した。

・Azacitidine(終濃度:各々0、1、10、100、1000および10000 nmol/L);および
・Navitoclax(終濃度:各々0、50、500および5000 nmol/L)(なお、Navitoclaxとの併用における化合物Bの濃度は1000 nmol/Lである。)。
37℃/5%CO2条件下にて48時間当該細胞株を培養した後、各ウェルにCell Counting Kit-8(Dojindo)を10μL添加し、続いて60分間培養後、マイクロプレートリーダーで各wellにおける吸光度(450nm)を測定した。その結果を図13、14および15に各々に示す。なお、図中、縦軸の「シグナル強度」は、吸光度値(450nm)を表し、当該数値が低いほど高い抗腫瘍作用を示していることを表す。
化合物Bは、ヒト急性骨髄性白血病細胞株KG-1α、THP-1およびCMK各々に対する、Venetoclax、AzacitidineおよびCytarabine夫々の抗腫瘍作用を増強し、また、ヒトB細胞リンパ腫細胞株DOHH2およびOLI-Ly3各々に対する、Navitoclaxの抗腫瘍作用も同様に増強した。
