Description

本発明は、デコイ等の核酸医薬を効果的に経口投与することができる、核酸医薬製剤に関する。   The present invention relates to a nucleic acid pharmaceutical preparation capable of effectively orally administering a nucleic acid pharmaceutical such as decoy.

DNAデコイ等のオリゴヌクレオチドからなる核酸医薬は、酸あるいは酵素(ヌクレアーゼ等)に不安定であるため、従来は局所投与に限定され、それ以外は安定化誘導体の静脈内投与が一部検討されているに過ぎなかった。   Nucleic acid pharmaceuticals consisting of oligonucleotides such as DNA decoys are unstable to acids or enzymes (nucleases, etc.), so they have been limited to local administration in the past. I was just there.

しかしながら慢性疾患など継続/反復投与が必要とされる疾患に対し、経皮剤を除く局所投与は現実的ではなく、また静脈内投与も病院でしか実施できず在宅治療には利用できないことから、核酸医薬の優れた薬理作用を生かすには、経口投与製剤の開発が広く求められていた。   However, for diseases that require continuous / repeated administration such as chronic diseases, local administration excluding transdermal agents is not practical, and intravenous administration can only be performed in hospitals and cannot be used for home treatment. In order to take advantage of the excellent pharmacological action of nucleic acid drugs, development of oral dosage forms has been widely demanded.

一方、現時点で炎症性腸疾患に対し承認されているのはメサラジン(Mesalazine, 5-アミノ-2-ヒドロキシ安息香酸)のみであるが、メサラジンはアスピリン誘導体であり、薬理学的にはシクロオキシゲナーゼ阻害作用に基づく抗炎症剤である。従って抗炎症剤としての対症療法しか期待できず、継続投与するとシクロオキシゲナーゼのインダクション(酵素誘導)が起こりリバンド(再発)する問題点も指摘されていた。一方でNF-κBデコイは酵素阻害剤ではないため、リバンドが起こる可能性はない。さらにメサラジンの投与量は、1,500〜2,250mg/日(潰瘍性大腸炎)、1,500〜3,000 mg/日(クローン病)と大量であり、毎日この量を継続服用するのは非常に困難であり、コンプライアンス(服薬遵守)面での問題もあった。   On the other hand, only mesalazine (Mesalazine, 5-amino-2-hydroxybenzoic acid) is currently approved for inflammatory bowel disease, but mesalazine is an aspirin derivative and has a cyclooxygenase inhibitory action pharmacologically. Is an anti-inflammatory agent based on Therefore, only symptomatic treatment as an anti-inflammatory agent can be expected, and it has been pointed out that cyclooxygenase induction (enzyme induction) occurs and rebands (recurs) when it is continuously administered. On the other hand, since NF-κB decoy is not an enzyme inhibitor, there is no possibility of rebanding. Furthermore, the dose of mesalazine is large, 1,500-2,250 mg / day (ulcerative colitis), 1,500-3,000 mg / day (Crohn's disease), and it is very difficult to take this amount every day. There were also problems with compliance.

(3) Effect of three-layer seamless soft capsule formulation in mouse inflammatory bowel disease model
1) Method Animal experiments used TNBS (2,4,6-trinitrobenzenesulfonic acid) -induced chronic enteritis mice as a clinical model. To induce inflammation in the large intestine of 7-week-old male C57BL / 6J mice (about 22 g), TNBS 4 mg dissolved in 50 μL of 25% ethanol and adjusted to a total volume of 200 μL was injected into the large intestine by enema. Thereafter, the same amount of TNBS solution was injected into the large intestine every week (7th, 14th, and 21st days) to maintain a chronic pathological condition.

慢性炎症の完成した7日目から前記3層シームレスソフトカプセルの大腸内投与(経肛門)を開始した。投与回数は週2回(9、13、16、20、23、27日目)で、28日目(4週目)に組織の摘出を行い、有効性の評価は生存率、体重変化、Disease activity index (DAI)、大腸長の変化で行った。なお、DAIはClin Exp Immunol. 2000 Apr;120(1):51-8.に従い、以下の項目の点数を合計しスコアを算出した(体重減少率スコア+便性状スコア+血便スコア、最低0〜最大12)。   On the 7th day after the completion of chronic inflammation, administration of the three-layer seamless soft capsule into the large intestine (transanal) was started. The frequency of administration is twice a week (9th, 13th, 16th, 20th, 23rd and 27th days). Tissues are removed on the 28th day (4th week), and efficacy is evaluated by survival rate, weight change, disease Activity index (DAI), changes in large intestine length. DAI was calculated according to Clin Exp Immunol. 2000 Apr; 120 (1): 51-8. The score was calculated by adding the scores of the following items (weight loss rate score + fecal property score + blood stool score, minimum 0- Up to 12).

Figure 2014037358

慢性腸炎を誘発したマウスは、下記6群に無作為に振り分けた。
1. シャム群(食液の注入により大腸炎の誘発なし)
2. コントロール群(慢性腸炎誘発マウス)
3. 低用量治療群(慢性腸炎誘発後にNF-κBデコイ製剤2.26mg/kg投与)
4. 低用量ダミー群(慢性腸炎誘発後に低用量群と同じ量のダミー製剤を投与)
5. 高用量治療群(慢性腸炎誘発後にNF-κBデコイ製剤11.32mg/kg投与)
6. 高用量ダミー群(慢性腸炎誘発後に高用量群と同じ量のダミー製剤を投与)
Mice that induced chronic enteritis were randomly assigned to the following 6 groups.
1. Siamese group (no colitis induced by infusion of food)
2. Control group (chronic enteritis-induced mice)
3. Low-dose treatment group (NF-κB decoy preparation 2.26 mg / kg administered after induction of chronic enteritis)
4. Low-dose dummy group (administer the same amount of dummy as the low-dose group after induction of chronic enteritis)
5. High-dose treatment group (11.32 mg / kg of NF-κB decoy preparation after induction of chronic enteritis)
6. High-dose dummy group (administer the same amount of dummy preparation as the high-dose group after induction of chronic enteritis)

2) 結果
高用量治療群はコントロール群に比べ、体重減少(図1)、DAI(図2)そして大腸長の短縮は軽度であった(図3)。その結果、デコイ治療群は用量依存的に有意な生存率の改善を認め(図4)、本製剤の有効性が確認された。
2) Results In the high-dose treatment group, weight loss (Figure 1), DAI (Figure 2), and shortening of the colon length were milder than those in the control group (Figure 3). As a result, the decoy treatment group showed a significant improvement in survival rate in a dose-dependent manner (FIG. 4), confirming the effectiveness of this preparation.
