Definitions
- the present invention relates to an external medicine for treating skin diseases and a method for producing the same.
- tuberous sclerosis a genetic disease called tuberous sclerosis (TSC) is known.
- This genetic disease is a disease that causes central nervous system disorders (epilepsy, delayed mental development, autism, etc.) and vitiligo in addition to systemic tumors such as skin tumors.
- the causative gene of this genetic disease is TSC1 encoding a hamartin protein and TSC2 encoding a tuberin protein.
- the complex of hamartin protein and tuberin protein is located upstream of mTOR and suppresses the function of mTOR. It is believed that suppression of mTOR disappears due to the failure of at least one of the hamartin and tuberin proteins, resulting in tuberous sclerosis.
- suppression of mTOR is effective, and attempts have been made to use sirolimus, an inhibitor of mTOR.
- sirolimus was systemically administered to patients with tuberous sclerosis in order to treat brain tumors, kidney tumors and lung tumors, and it was reported that good results were obtained. ing. However, it was confirmed that when the administration of sirolimus was discontinued, the above-mentioned tumor increased again, and it is considered necessary to continue systemic administration of sirolimus for a long time in order to maintain the tumor shrinkage. Yes. This result applies not only to brain tumors, kidney tumors and lung tumors but also to skin tumors, and systemic administration of sirolimus is required over a long period of time to treat this skin tumor.
- Non-Patent Documents 1 to 3 describe applying an external medicine for sirolimus to angiofibromas formed on the face of patients with tuberous sclerosis.
- Non-Patent Document 3 describes that an ointment containing sirolimus is applied to a skin tumor in an animal model of tuberous sclerosis.
- Non-Patent Documents 4 and 5 describe applying a formulation containing sirolimus to human psoriasis vulgaris.
- Non-Patent Document 5 describes that sirolimus is locally applied to human port wine nevus.
- a compound used for an external medicine has a large molecular size and a decrease in diffusibility when the molecular weight is large, so that the absorption of the compound from the skin decreases ( Michiteru Otani, Nuri-Yaku-no-Sakura, Vol. 2, maruho, Maruho Corporation, page 4, 2009). For this reason, it is recommended that the compound used for external medicine has a molecular weight of 500 Dalton or less.
- Non-Patent Documents 1 and 2 describe that angiofibroma has been improved by using a topical sirolimus drug, but it can be said that it is not at a practical level. There is a need for the development of a topical drug that can further increase the absorption of sirolimus from the skin.
- Non-Patent Document 3 the blood concentration of sirolimus 24 hours after applying an ointment containing 0.4% by mass of sirolimus to a skin tumor was 6.3 ⁇ 0.6 ng / mL. It is described. Similarly, it is described that the blood concentration of sirolimus 24 hours after applying an ointment containing 0.8% by mass of sirolimus to a skin tumor was 12.3 ⁇ 1.5 ng / mL. ing. The blood concentration of sirolimus is almost equal to the general blood concentration (5 to 10 ng / mL) when sirolimus is administered systemically. As described above, in the technique described in Non-Patent Document 3, sirolimus migrates into the blood despite being applied locally, and is affected in the same manner as systemic administration of sirolimus. Side effects will occur.
- the concentration of sirolimus in a skin tumor 24 hours after applying an ointment containing 0.4% by mass of sirolimus to a skin tumor is 13.8 ⁇ 0.7 ng / mL. This concentration is about 1.9 to 2.5 times the blood concentration (6.3 ⁇ 0.6 ng / mL).
- the concentration of sirolimus in the skin tumor 24 hours after application of the ointment containing 0.8% by weight of sirolimus to the skin tumor is 59.6 ⁇ 23.5 ng / mL. This concentration is about 2.6 to 7.7 times the blood concentration (12.3 ⁇ 1.5 ng / mL).
- the concentration of sirolimus present in the skin tumor is only a few times the concentration of sirolimus that migrates into the blood. From this, it can be said that the ointment disclosed in Non-Patent Document 3 is not suitable for local application.
- Non-Patent Document 4 is a lotion composed of sirolimus, capric acid, isopropyl myristate and benzyl alcohol.
- the content of sirolimus in this formulation is 2.2% by mass or 8% by mass, and side effects such as contact dermatitis and irritation are caused by applying these formulations to the affected area.
- sirolimus concentration of 8% by mass is a concentration that deviates from the common general knowledge of those skilled in the art, and it is not practical to use a gel having such a concentration as an external preparation.
- Non-Patent Document 5 it is not sufficient to apply sirolimus locally to the affected area in order to treat port wine nevus. In addition to using sirolimus, laser irradiation to the affected area is not sufficient. Irradiation is necessary. Thus, in the techniques described in Non-Patent Documents 4 and 5, as described above, sirolimus is poorly absorbed from the skin, so that the amount applied to the affected area can be increased or combined with another treatment method. Needed.
- Patent Document 1 does not discuss at all whether sirolimus actually exerts a therapeutic effect on various diseases.
- the present invention has been made in view of the above-mentioned problems, and its purpose is to provide an external medicine capable of absorbing a sufficient amount of sirolimus to treat an affected area without causing side effects. It is to provide.
- a solution containing at least one of sirolimus and its derivative (active ingredient) is gelled, or at least one of the active ingredients.
- the present invention has been completed.
- the external preparation for locally treating skin diseases of the present invention includes a gel composition or an ointment composition containing at least one of sirolimus and its derivatives.
- “treating locally” is intended not to indicate a systemic effect due to a locally applied topical drug.
- the external preparation of the present invention When applied to the skin, the external preparation of the present invention has the effect of absorbing at least one of sirolimus and a derivative thereof sufficient to treat a skin disease to the affected area without causing side effects.

- the external preparation of the present invention can effectively treat tuberous sclerosis hemangiofibroma without causing side effects. This indicates that the external preparation of the present invention is also effective against other skin tumors (for example, benign tumors of the skin) based on dysregulation of mTOR. Moreover, it was shown that the external medicine of the present invention penetrated into the dermis by treating facial angiofibroma of tuberous sclerosis.
- vitiligo using the external preparation of the present invention One of the causes of vitiligo is caused by the fact that melanocytes do not produce melanin. Proteins involved in the production of melanin in melanocytes are MITF, TYR, DCT, TYRP1.
- vitiligo often occurs in patients suffering from diseases (such as tuberous sclerosis) resulting from activation of mTOR.
- diseases such as tuberous sclerosis
- the present inventors consider that the mechanism by which vitiligo occurs in such patients is as follows. As a result of activation of mTOR in the patient's melanocytes, the activity of S6K1 increases. And by this increase in the activity of S6K1, the activity of PI3K is suppressed. Since PI3K not only activates the Akt signaling pathway, but also activates the MAPK signaling pathway, suppression of PI3K activity suppresses the Akt signaling pathway and the MAPK signaling pathway.

- Tacrolimus or pimecrolimus is used as a treatment for atopic dermatitis. It is known that the effect on atopic dermatitis such as tacrolimus is exhibited by binding tacrolimus or the like to FKBP12 (immunophilin) and suppressing calcineurin. However, tacrolimus has a side effect of causing tumors.
- sirolimus binds to FKBP12 like tacrolimus, but suppresses mTOR rather than calcineurin.

シロリムスの試薬の代わりにRapamune(ファイザー社製、29269)を用いたことを除いて、調製例5と同様の作業を行い、0.2質量%のシロリムスを含む軟膏(軟膏3)を調製した。具体的には、2mgのRapamuneの錠剤を粉砕し、不純物を取り除くために75μmのメッシュを通してから、粉砕物を炭酸プロピレン58mgに溶解させた。
プロトピック(登録商標)軟膏0.03%小児用(アステラス製薬株式会社)を基剤として0.2質量%のシロリムスを含んでいる軟膏(参考例1)を調製した。
プロトピック(登録商標)軟膏0.03%小児用の代わりに、プロトピック(登録商標)軟膏0.1%を用いたことを除いて、参考例1と同様の作業を行い、0.2質量%のシロリムスを含んでいる軟膏(参考例2)を調製した。
本実施例では、以下のような試験を実施して、本発明の外用薬が人工皮膚から吸収される量を確認した。
TESTSKIN(登録商標)LSE-d、およびTESTSKIN(登録商標)LSE-high(TOYOBO)の各トランスウェル内の皮膚に、上述の本発明の外用薬(軟膏2および3、並びに、ゲル2および3)をそれぞれ塗布した。なお、リング内の吸収面の直径は、1cmであった。
ゲル2、軟膏2および参考例1を用いて得られた試験の結果を図1に示す。図1に示すように、ゲル2を用いた場合、真皮中のシロリムスの濃度が8.08±3.85ng/mgであり、軟膏2を用いた場合、真皮中のシロリムスの濃度が10.03±2.68ng/mgであり、タクロリムスの軟膏基剤を用いた場合、真皮中のタクロリムスの濃度が1.82±0.319ng/mgであった。また、ゲル2と参考例1との間のp値および軟膏2と参考例1との間のp値は、どちらも0.05未満であった。このp値から、ゲル2および軟膏2と参考例1との間に有意差があることが確認された。以上のことから、参考例1よりもゲル2および軟膏2の方が、有効成分をより効率よく皮膚へ浸透できることが分かった。
<試験方法>
上述した調製例5に従い、0.03質量%のシロリムスを含む軟膏(軟膏4)、0.06質量%のシロリムスを含む軟膏(軟膏5)、0.1質量%のシロリムスを含む軟膏(軟膏6)を調製した。
軟膏3(0.2質量%)を用いた場合、真皮中のシロリムスの量は、294.2±100.7pg/mLであり、軟膏2(0.2質量%)を用いた場合、真皮中のシロリムスの量は、333.1±123pg/mLであり、軟膏4(0.03質量%)を用いた場合、真皮中のシロリムスの量は、67.59±22.1pg/mLであり、軟膏5(0.06質量%)を用いた場合、真皮中のシロリムスの量は、80.31±20.6pg/mLであり、軟膏6(0.1質量%)を用いた場合、真皮中のシロリムスの量は、103.06±22.3pg/mLであった。
本実施例では、以下のような試験を実施して、本発明の外用薬の、結節性硬化症の皮膚腫瘍に対する効果を確認した。したがって、結節性硬化症以外の皮膚の良性腫瘍(脂漏性角化症など)に対しても効果が期待される。
結節性硬化症の患者を、上記軟膏3を用いて処置される患者のグループ(4人)、および上記ゲル3を用いて処置される患者のグループ(8人)に分けた。各患者に対して、上述した外用薬を1日2回、12週間塗布した。具体的には、患者の顔面の左側および右側のどちらか一方の血管線維種に外用薬を塗布し、他方の血管線維腫に、有効成分(シロリムス)を含まない基剤のみ(コントロール)を塗布した。処置の開始から12週間後に処置を中止した。そして、処置を中止してから3ヶ月間、血管線維腫の経過観察を行った。なお、ゲル3を用いて処置される患者の一人が、決められた通りの外用を適切に行わなかったため、試験中に除外された。
図3~5に、ゲル3を用いた処置の開始前および処置の開始から12週間後の血管線維腫の写真を示す。図3~5に示すように、患者の左頬の血管線維腫には、ゲル3を塗布し、患者の右頬の血管線維腫には、コントロールを塗布した。
白斑が発症する原因の一つは、メラノサイトがメラニンを産生しなくなることによって生じる。メラノサイトにおけるメラニンの産生に関与するタンパク質は、MITF、TYR、DCT、TYRP1である。
(試験方法)
1.4×105個のメラノサイトを6ウェルのカルチャープレートのウェルに播種し、medium 254(倉敷紡績株式会社製、M254500)をウェルに添加した。次いで、このプレートを、37℃および5%CO2の環境下にて24時間インキュベートした。
上述した試験の結果を図10~12に示す。
(試験方法)
6ウェルに対して、メラノサイト(2人の正常な人に由来するメラノサイト(以下、各々をメラノサイト1およびメラノサイト2と呼ぶ))を播種した。なお、メラノサイトの数は、1ウェルあたり2×105個であり、培地としてはmedium254/HMGS2(PMA(-)(抗生剤無し)を用いた。
細胞数1×104当りの量に補正したメラニンの量を、図23および図24に示す。なお、図23は、メラノサイト1のデータを示し、図24は、メラノサイト2のデータを示している。
結節性硬化症の患者における白斑に、上記ゲル3または上記軟膏3を1日当たり2回、6週間塗布した。図13に、ゲル3の塗布開始前の白斑の写真(a)、およびゲル3の塗布開始から6週間後の白斑の写真(b)を示す。図14に、軟膏3の塗布開始前の白斑の写真(a)、および軟膏3の塗布開始から6週間後の白斑の写真(b)を示す。図13および図14中の矢印は白斑を示す。図13の(b)および図14の(b)では、同図の(a)に示された白斑が消退している。また、丘疹および紅色局面も軽快している。よって、ゲル3または軟膏3を塗布することによって白斑を処置できることが示された。
尋常性白斑(頚部または腹部に発症した尋常性白斑)に、上記ゲル3または上記軟膏3を1日当たり2回、2ヶ月間塗布した。図27および図28に、2人の患者の尋常性白斑の写真を示す。図27および図28から明らかなように、2人の患者の何れにおいても、尋常性白斑が消退した。
アトピー性皮膚炎の処置薬としては、タクロリムスまたはピメクロリムスが使用されている。タクロリムスなどのアトピー性皮膚炎に対する効果は、タクロリムスなどがFKBP12(イムノフィリン)と結合して、カルシニューリンを抑制することによって発揮されることが知られている。しかし、タクロリムスなどは、腫瘍を発生させるという副作用を有している。
マウスの背中の皮膚に、ダニの抗原を含んでいる軟膏(ビオスタAD、ビオスタ株式会社製、AD001)を2週間塗布することによってこの皮膚にアトピー性皮膚炎を誘発した。具体的には、マウスの背中の毛を剃り、背中の皮膚を露出させた。そして、ダニの抗原を含んでいる軟膏を、この軟膏の塗布開始日(0日目)、この塗布開始日から4日目、7日目、11日目、14日目、18日目、21日目、および25日目に、背中の露出した皮膚に塗布した。
アトピー性皮膚炎の評価の結果を図15および図16に示す。図15は、上述した軟膏を用いた処置の各時点における、3匹のマウスのそれぞれにおける総合的なスコアを示すグラフである。図15の(a)は、ポジティブコントロールを用いた場合の各マウスにおける総合的なスコアを示すグラフであり、(b)は、軟膏2を用いた場合の各マウスにおける総合的なスコアを示すグラフであり、(c)は、ネガティブコントロールを用いた場合の各マウスにおける総合的なスコアを示すグラフである。図15の(a)~(c)における「A」~「I」は、試験に用いたマウスを示す。図15の(a)~(c)において、横軸の「1」~「5」は、それぞれ処置の開始(0日目)、処置の開始から7日目、処置の開始から14日目、処置の開始から21日目、および処置の開始から28日目を示す。
紅斑は、血管新生の盛んな部位である。このような紅斑が、mTORの活性化に起因する疾患(結節性硬化症など)に罹患した患者においてしばしば発生することが知られている。本発明者らは、このような疾患において紅斑が発生するメカニズムが以下のとおりであると考えた。
(試験方法)
重症の血管線維腫を有する患者、中等症の血管線維腫を有する患者、および軽症の血管線維腫を有する患者からそれぞれ、重症、中等症、または軽症の血管線維腫の細胞を単離した。血管線維腫の細胞は、線維芽細胞の一般的な初代培養法(黒木登志男他編:分子生物学研究のための新培養細胞実験法 実験医学 別冊 バイオマニュアルUPシリーズ 改定第2版、羊土社 参照)にしたがって各患者の顔面から単離した。患者から取得した細胞はいずれも患者の同意を得た上で用いた。
上述した試験の結果を図18に示す。図18において、Aは重症の血管線維腫の細胞を示し、Bは中等症の血管線維腫の細胞を示し、Cは軽症の血管線維腫の細胞を示す。図18に示すように、重症の血管線維腫の細胞を用いた場合のVEGFの濃度は468.857pg/mLであり、中等症の血管線維腫の細胞を用いた場合のVEGFの濃度は260.286pg/mLであり、軽症の血管線維腫の細胞を用いた場合のVEGFの濃度は147.429pg/mLである。このように、血管線維腫の細胞においてVEGFが発現しており、血管線維腫の症状が重くなるほど、VEGFの発現量が高くなることが分かった。
(試験方法)
結節性硬化症の患者から単離した血管線維腫の細胞、ヒト線維芽細胞、HaCatを用いた。血管線維腫の細胞の単離は、この血管線維腫の切除を希望する患者から血管線維腫を切除し、上述した初代培養法を用いて行った。ヒト線維芽細胞は、結節性硬化症(TSC)でない患者の組織から、上述した初代培養法を用いて取得した。HaCatは、ドイツ連邦共和国癌研究センター(dkfz)から購入した。患者から取得した細胞はいずれも患者の同意を得た上で用いた。
上述した試験の結果を図19に示す。
結節性硬化症の患者の紅斑に、上記軟膏3を1日当たり2回、12週間塗布した。図20に、軟膏3の塗布開始前の紅斑の写真(a)、および軟膏3の塗布開始から12週間後の紅斑の写真(b)を示す。図20中の矢印は紅斑を示す。図20(b)では、同図の(a)に示された紅斑が消退している。よって、軟膏3を塗布することによって紅斑を処置できることが確認された。
本実施例にて調製した軟膏中にてシロリムスがどのような状態であるのかを確認するために、シロリムスの溶媒である炭酸プロピレンが軟膏中にてどのような状態であるのかを調べた。
