- ⁇ Chemical solution preparation and filling> 2000 mL of water for injection was put into a 5 L stainless steel container. Furthermore, the polysorbate solution obtained above was added. Further, water for injection was added to make the total amount 4000 g, and the mixture was uniformly mixed and stirred.

An ampule was filled with 1.1 g of the filtrate to obtain a placebo preparation.
- Example 1 ⁇ Test method> Using TMD-123 produced according to Production Example 1 as thrombomodulin, a randomized double-blind placebo subject study was conducted in patients who developed sepsis and DIC. The total number of target patients was 750, of which 741 patients (370 patients receiving TMD-123 and 371 patients receiving placebo) were administered the study drug. TMD-123 was administered rapidly intravenously once a day for 6 consecutive days at a dose of 0.06 mg / kg. A placebo manufactured according to Production Example 7 was used. In addition, for patients over 100 kg in weight, rapid intravenous administration was performed once a day for 6 days continuously at a fixed dose of 6 mg for the purpose of suppressing the occurrence of side effects due to overdose.

- the difference in mortality was the maximum (9.7%) in the patients with the above, showing a high difference in mortality, both absolute and relative to other INR lower limits (Table 2).
- patients with severe sepsis who have at least one organ disorder selected from the group consisting of cardiovascular disorder, respiratory disorder, kidney disorder, and liver disorder are compared to those with sepsis without organ disorder.
- the difference in mortality between TMD-123 and placebo was large. (The former: 5.4%, the latter: -1.1%)
- the medicament containing the thrombomodulin of the present invention is useful as a medicament capable of effectively treating and / or improving sepsis in a severe sepsis patient whose INR of a patient's plasma specimen is greater than 1.4.

<トロンボモジュリンの取得>
上記の方法、すなわち、配列番号9のアミノ酸配列をコードするDNA(具体的には、配列番号10の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて、50mmol/L NaClを含む20mmol/Lリン酸塩緩衝液(pH7.3)で活性画分を回収した高純度精製品を取得した。さらに限外濾過膜を用いて濃縮し、11.0mg/mLのトロンボモジュリン(本明細書においてTMD123と略すことがある)溶液を取得した。
ガラスビーカーにポリソルベート80を0.39g量り、注射用水を30mL加えて溶解した。
5Lのステンレス製容器に、上記得られたTMD123溶液2239mL(可溶性トロンボモジュリンのたん白質量として24.63gに相当。ただし5%過量仕込み。)を入れた。さらに、上記で得られたポリソルベート溶液を加え、塩化ナトリウム27.9gを加えた。注射用水を600mL加え撹拌した。1mol/L塩酸溶液を添加して、pHを6.0に調整した。さらに注射用水を加えて全量を3940gとして均一に混合撹拌した。この薬液を、孔径が0.22μmのフィルター(ミリポア製MCGL10S)で濾過滅菌した。濾過液を1.1gずつアンプルに充填して、TMD123製剤を得た。
配列番号11のアミノ酸配列をコードするDNA(具体的には、配列番号12の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて精製されたトロンボモジュリン(本明細書においてTMD123Mと略すことがある)溶液を取得し、上記と同様の方法によりTMD123M製剤を取得する。
配列番号1のアミノ酸配列をコードするDNA(具体的には、配列番号2の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて精製されたトロンボモジュリン(本明細書においてTME456と略すことがある)を取得し、上記と同様の方法によりTME456製剤を取得する。
配列番号3のアミノ酸配列をコードするDNA(具体的には、配列番号4の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて精製されたトロンボモジュリン(以下、TME456Mと略すことがある)を取得し、上記と同様の方法によりTME456M製剤を取得する。
配列番号5のアミノ酸配列をコードするDNA(具体的には、配列番号6の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて精製されたトロンボモジュリン(本明細書においてTMD12と略すことがある)を取得し、上記と同様の方法によりTMD12製剤を取得する。
配列番号7のアミノ酸配列をコードするDNA(具体的には、配列番号8の塩基配列よりなる)を、チャイニーズハムスター卵巣(CHO)細胞にトランスフェクションして、この形質転換細胞の培養液より前述した定法の精製法にて精製されたトロンボモジュリン(以下、TMD12Mと略すことがある)を取得し、上記と同様の方法によりTMD12M製剤を取得する。
<ポリソルベート溶液調製>
ガラスビーカーにポリソルベート80を0.4g量り、注射用水を30mL加えて溶解した。
5Lのステンレス製容器に、注射用水を2000mLを入れた。さらに、上記で得られたポリソルベート溶液を加えた。さらに注射用水を加えて全量を4000gとして均一に混合撹拌した。この薬液を、孔径が0.22μmのフィルター(ミリポア製MCGL10S)で濾過滅菌した。濾過液を1.1gずつアンプルに充填して、プラセボ製剤を得た。
<試験方法>
製造例1に準じて製造したTMD-123をトロンボモジュリンとして使用し、敗血症並びにDICを発症した患者を対象とした無作為二重盲検プラセボ(Placebo)対象の試験を行った。対象患者数は総数750例であり、うち治験薬が投与された患者が741例(TMD-123投与群370例、プラセボ投与群371例)として試験を実施した。TMD-123は、0.06mg/kgの用量で1日1回、6日間連続静脈内急速投与された。プラセボとしては製造例7に準じて製造されたものを用いた。
なお、体重100kgを超える患者に対しては、過量投与による副作用発現を抑える目的で、一律6mgの固定用量にて1日1回、6日間連続静脈内急速投与された。
また、対象患者からは、肝臓又は腎臓のみの臓器障害を有する患者を除いた。肝臓又は腎臓のみの臓器障害を有する患者では、薬剤性臓器障害等、敗血症に限定されない要因から臓器障害が発現している可能性が想定されるためである。
投与開始から28日目の転帰を確認し、各患者群の死亡率(Mortality)を算出した。
また、TMD-123とプラセボ間の死亡率差をDifferenceとして算出した。
臓器障害を有さない敗血症患者においては、治験薬投与前の血漿中INR値が、INR>1.5の患者で、TMD-123を投与した際の死亡率とプラセボを投与した際の死亡率との差(死亡率差:Difference)が最大(6.1%)となり、INR>1.6の患者における死亡率差がそれに次いだ(4.5%)。INR>1.4の患者では死亡率差1.7%程度と、絶対的にも相対的にもそれほど高い死亡率差を示さなかった(表1)。
すなわち、表1より、INR下限値の極大は1.5~1.6の間にあり、INRの下限値が1.5~1.6の外にある場合には、死亡率差が極端に下がることがわかった。
