Definitions
- the present invention relates to a GLP-1 analog composition for a microneedle device.
- GLP is a glucagon-like peptide, originally an incretin hormone secreted from the human digestive tract mucosa.
- An analog preparation of GLP-1 is an agonist of GLP-1 receptor, secreted from the small intestine in vivo, and promotes insulin secretion in pancreatic ⁇ cells in the periphery, and pancreatic ⁇ cells Inhibits glucagon secretion in the brain and acts as an antifeedant hormone in the center.
- GLP-1 enhances insulin secretion and effectively lowers blood glucose only when the insulin secretion stimulating concentration is reached, that is, depending on the glucose concentration. Due to these characteristics, GLP-1 is considered to be a drug candidate suitable for the treatment of type 2 diabetes.
- Non-patent Documents 1 and 2 since GLP-1 secreted in vivo is rapidly degraded by dipeptidyl peptidase-4 (DPP-4), the elimination half-life (t 1/2 ) is very short (1 after intravenous administration). (Less than 5 minutes), and since the duration of action is short, it is not suitable as a therapeutic drug for diabetes, and therefore various drugs such as GLP-1 analogs have been developed (Non-patent Documents 1 and 2).
- Lixenatide is a human GLP-1 analog preparation for the treatment of type 2 diabetes.

- lixenatide was administered to hairless rats (repeated number of tests 3 times).
- Example 11 water formulation, MN-w
- Example 12 PG formulation, MN-PG
- Example 13 G formulation, MN-G 1 month in an environment of 60 ° C. for 1 month I left it alone.
- the standing was performed while deoxidizing with a deoxidizing agent (PK (+)) or without deoxidizing (PK ( ⁇ )).
- FIG. 8 is a graph showing the lixenatide content after standing as a relative value with respect to the initial value.
- PK (+) deoxidizing agent
- PK ( ⁇ ) deoxidizing
- the composition of the water formulation is excellent without any problems with regard to solubility, coating properties, blood profile and stability.
- a polymer carrier is preferably a polymer carrier (for example, pullulan) that can increase the viscosity at a low concentration in order to prevent a decrease in the concentration of lixenatide.
- a polyhydric alcohol may be selected as a solvent for dissolving or dispersing the drug.
- glycerin and propylene glycol have a higher viscosity than water, when they are used as a solvent, a composition having a viscosity suitable for coating can be easily formed without using a polymer carrier.
- polyhydric alcohol is suitable. According to the propylene glycol and glycerin used in the examples, both solubility and blood profile are good.
- the glycerin formulation was good, whereas the propylene glycol formulation tended to cause dripping.
- the PG prescription shows a good blood concentration profile in the results of the in vivo administration test, and the bioavailability is also high, so it is considered that there is no particular problem. It is considered that the coating properties of the PG formulation can be sufficiently improved by methods such as further increasing the drug concentration and adding a viscosity improver highly compatible with PG.

Abstract
Description
(実施例1~6)
チューブに、リキセナチドと溶媒を、表1に示す含有比で混合した。作製した混合液をスターラーにより撹拌(1500rpm、12時間、25℃)し、高分子化合物の溶解性を目視にて以下の基準にしたがって評価した。評価結果を表1に示す。
A:完全に溶解している
B:一部溶解している
C:溶解していない
a:コーティングに好適である
b:コーティングに好適でない
溶媒を水とし、さらに高分子担体を加え、表2に示す含有比で混合した。混合物の相溶性と粘度を実施例1~6と同様に評価した。評価結果を表2に示す。
(実施例8~10)
チューブに、リキセナチドと溶媒(及び高分子担体)を、表3に示す質量比で混合して、GLP-1アナログ組成物を得た。実施例8は水を溶媒として用いた水処方の組成物であり、実施例9はプロピレングリコール(PG)を溶媒として用いたPG処方の組成物であり、実施例10はグリセリン(G)を溶媒として用いたG処方の組成物である。
(実施例11~13)
実施例8~10で得られたGLP-1アナログ組成物をマイクロニードルにコーティングし、マイクロニードルアレイを得た。マイクロニードル上にコーティングされたリキセナチドの含量は、水処方で7.96μg/patch/headであり、PG処方で12.2μg/patch/headであり、G処方で9.64μg/patch/headであった。上記マイクロニードルアレイを有する衝撃アプリケータを用いて、リキセナチドをヘアレスラットに投与した(繰り返し試験数3回)。
チューブに、リキセナチドと生理食塩水を、50:50の質量比となるように加え、ミキサーで混合した。得られた混合物を15.1μg/300μL/headの条件で、ヘアレスラットに皮下投与した(繰り返し試験数3回)。その後、実施例11~13と同様に血中のリキセナチド濃度を測定した。測定結果を図4に示す。図4において、「s.c」は皮下投与を示す。AUC値及びBA値を表4に示す。
実施例11(水処方、MN-w)、実施例12(PG処方、MN-PG)、実施例13(G処方、MN-G)それぞれのマイクロニードルアレイを60℃の環境下で1か月放置した。放置は、脱酸素剤による脱酸素処理しながら(PK(+))、又は脱酸素処理無し(PK(-))で行った。図8は、放置後のリキセナチド含有量を、初期の値に対する相対値で示すグラフである。水処方及びPG処方では放置後も安定したリキセナチド含有量が維持されていた。G処方の場合、リキセナチドのマイクロニードルへの吸着が進行して、抽出されるリキセナチドの量が減少した。ただし、脱酸素処理を行うことにより、安定性が改善する傾向にあることが確認された。
水処方
水処方の組成物は、溶解性、コーティング性状、血中プロファイル及び安定性の全てに関して問題なく優れている。ただし、マイクロニードルへのコーティングに適した粘度を得るために、高分子担体を組成物に添加することが望ましい。高分子担体は、リキセナチド濃度の減少を防ぐためにも、低濃度で粘度を高められる高分子担体(例えば、プルラン)が望ましい。
薬物を溶解又は分散させる溶媒としては、水だけでなく、多価アルコールも選択される場合がある。特に、グリセリン及びプロピレングリコールは、水よりも粘度が高いため、これらを溶媒として用いると、高分子担体を用いなくとも、コーティングに適した粘度を有する組成物を形成し易い。特に、多価アルコールに対する溶解度が高い(例えば、飽和濃度30質量%以上)薬剤の場合、多価アルコールが好適である。実施例において使用したプロピレングリコール及びグリセリンによれば、溶解性及び血中プロファイルが共に良好である。マイクロニードルへのコーティング性状に関しては、グリセリン処方は良好であるのに対し、プロピレングリコール処方は液ダレを起こす傾向があった。もっとも、PG処方は、In vivo投与試験の結果では良好な血中濃度プロファイルを示しており、バイオアベイラビリティーも高い値を示したため、特に問題とならないと考えられる。PG処方のコーティング性状は、薬物濃度をさらに高める、PGと相溶性の高い粘度向上剤を添加するなどの方法により十分改善できると考えられる。
