Definitions
- the present invention relates to a method for treating primary axillary hyperhidrosis and a pharmaceutical preparation containing a sofpironium bromide for treating, treating, or preventing primary axillary hyperhidrosis.
- Hyperhidrosis is a large amount of sweating on the palms and soles caused by heat, mental stress, or other causes, which interferes with daily life (for example, documents and notes are torn by sweat, and sweat is a concern. It is a state in which you cannot hold hands with others, you need to change your underwear many times a day, your mobile phone gets wet with sweat and breaks, etc.), which significantly reduces QOL (Non-Patent Document 1).
- Human sweat glands include eccrine sweat glands and apocrine sweat glands, and the sweat that causes hyperhidrosis is secreted from the eccrine sweat glands (Non-Patent Document 2).
- Eccrine sweat glands are regulated by cholinergic nerves, and acetylcholine is thought to induce sweating by stimulating M3 type muscarinic receptors located in the postsynaptic membrane of the nerves that control eccrine sweat glands (non-patented). Document 3).
- Hyperhidrosis is classified into systemic hyperhidrosis and local hyperhidrosis depending on whether the onset site is systemic or part of the body, and local hyperhidrosis often occurs in the palms, soles, and axilla. In addition, it is classified into primary disease with no particular cause and secondary disease caused by complications with other diseases (drug-induced or cardiovascular disease in the systemic system, peripheral neuropathy in the local area, etc.) depending on the pathogenesis. From the above, primary axillary hyperhidrosis can be defined as a condition in which a large amount of sweating occurs in the axilla regardless of a specific cause and interferes with daily life.
- the severity and therapeutic effect of primary hyperhidrosis are based on subjective symptoms in the following four stages: (1) sweating is not a concern at all and does not interfere with daily life; (2) sweating can be tolerated. However, there are occasional problems with daily life; (3) sweating is almost unbearable and frequently interferes with daily life; (4) sweating is unbearable and always interferes with daily life. It can be judged according to the Disease Severity Scale (HDSS, Strutton et al.). In HDSS, the judgment is made based on the above 4 scores (1) to (4), but since (3) and (4) are considered as severe indicators, the following specification also includes severe primary hyperhidrosis. Hyperhidrosis may refer to the pathology of HDSS scores (3) and (4). In addition, sweating amount measurement such as iodine paper method and weight measurement method is also used for determining the severity and therapeutic effect (Non-Patent Document 1).
- Non-Patent Document 4 the prevalence of primary axillary hyperhidrosis in Japan is 5.75%, and the average age of onset is 19.5. I'm old. Of these, the rate of consultations with medical institutions for patients with primary local hyperhidrosis, including axillary hyperhidrosis, was 6.3%, and 47.8% of all patients used non-antiperspirant deodorants, which is appropriate. It is a disease that requires the development of a proper treatment environment and awareness of patients.
- Non-Patent Document 1 the first choice for the treatment of primary axillary hyperhidrosis is simple topical or occlusive dressing (ODT) of aluminum chloride. If this does not work, the second option is intradermal administration of botulinum toxin type A (50 units of Botox® injection).
- Other options may include surgical therapies such as Endoscopic thoracic sympathectomy (ETS), nerve block, laser therapy, oral anticholinergic therapy, and psychotherapy.
- ETS Endoscopic thoracic sympathectomy
- Surgical therapy such as ETS is an irreversible treatment and cannot be easily applied clinically because compensatory sweating that causes abnormal sweating from other sites may occur.
- Oral therapy with anticholinergic agents causes systemic side effects such as dry mouth, drowsiness, and nausea due to anticholinergic action.
- Provansign® Tablets 15 mg, which has insurance coverage for hyperhidrosis in Japan, thirst (about 30%), constipation (about 12%), dysuria (about 9%), eyes The frequency of dysuria (about 9%) is relatively high.
- Oral anticholinergic therapy may not be available in sufficient efficacy due to these side effects.
- existing treatment methods have problems with invasive and systemic side effects, and there is a need for a drug capable of avoiding these problems.
- acetylcholine is known as one of the main neurotransmitters in the living body and has various pharmacological actions, and the sweating action by activation of sweat glands is one of them. Therefore, anticholinergic agents are useful in the treatment of hyperhidrosis by inhibiting the action of acetylcholine. Furthermore, by applying an anticholinergic agent externally, side effects associated with oral administration can be alleviated. In addition, side effects that may occur with existing treatments, such as the onset of irritant dermatitis in topical aluminum chloride therapy, or pain during injection when botulinum toxin is administered, and transient muscle weakness, etc. Side effects can be avoided.
- Soft glycopyrrolate is a derivative of glycopyrrolate, which is an anticholinergic agent, and one of the typical soft glycopyrrolate is sofpironium bromide.
- the sofpironium bromide has the following formula (I): It is an ester compound represented by (hereinafter, may be referred to as “BBI-4000” or “compound (I)”) and is a bromide salt of quaternary ammonium. So far, an external application preparation of sofpironium bromide and a method for treating hyperhidrosis using the same have been reported.
- Patent Document 1 discloses that soft glycopyrrolate can be used for the treatment of hyperhidrosis.
- Patent Document 2 suggests the therapeutic effect of BBI-4000 when applied topically in a subject with axillary hyperhidrosis.
- Patent Documents 3 and 4 show the safety of locally applied BBI-4000 and its effect on sweat production in subjects with hyperhidrosis (BBI-4000-CL-101 study).
- one of the problems to be solved by the present invention is to provide a clinically effective pharmaceutical preparation containing sofpironium bromide as an active ingredient and for external application.

Abstract
Description
塩化アルミニウムの外用投与は、日本では公的保険の適応でなく、かつ、刺激性皮膚炎が発現する場合があり、これを発症した場合には投薬の休止やステロイド外用剤による治療を要することから長期的な使用が難しい。
A型ボツリヌス毒素の皮内投与は、複数ヵ所(10~15ヵ所)に1~2 cm間隔で皮内投与するため、痛みを伴う治療である。また、誤投与を防止するためボトックス(登録商標)を使用する医師は実技講習を受ける必要があり、臨床上簡便に用いることができない。
抗コリン剤の内服療法は、抗コリン作用に起因する口渇、眠気、悪心等の全身性の副作用が発現する。国内で多汗症に対する保険適応を有するプロ・バンサイン(登録商標)錠15 mgのインタビューフォームによると、口渇(約30%)、便秘(約12%)、排尿障害(約9%)、眼の調節障害(約9%)の発生頻度が比較的高い。抗コリン剤の内服療法では、これらの副作用のために、十分な有効性を発揮できる量を使用できない場合がある。
以上のように、既存の治療方法には侵襲性及び全身性の副作用に問題があり、これを回避できる薬剤が求められている。

治療終了時のHDSSスコアが1又は2であり、治療終了時の両腋窩合計発汗重量のベースラインとの比が0.5以下の被験者の割合を下表に示した。
さらに、試験例1から移行後52週目のHDSSスコアが1又は2の被験者の割合は、0%/5%群76.6%(72/94名)、5%/5%群71.4%(65/91名)であった。
試験例1から移行後52週目の両腋窩合計発汗重量のベースラインとの比が0.5以下の被験者の割合は、0%/5%群66.6%(62/94名)、5%/5%群67.0%(61/91名)であった。
試験例1から移行後52週目の両腋窩合計発汗重量のベースラインからの変化量の平均値±標準偏差は、0%/5%群 -157.7±178.08 mg、5%/5%群 -141.6±168.47 mgであった。
様々なソフピロニウム臭化物製剤における粘度安定性試験
<調液方法>
各製剤は、ソフピロニウム臭化物、無水クエン酸、ミリスチン酸イソプロピル(2.5w/w%)、へキシレングリコール(10w/w%)、ヒドロキシプロピルセルロース(1.25w/w%)を含有する製剤である。ソフピロニウム臭化物、および無水クエン酸の濃度は表6に示した。全量が100%となるように、残分は無水エタノールで構成される。配合成分を無水エタノールに攪拌・溶解し各製剤を調製した。
粘度計を25℃、毎分10 rpm、プレヒート時間:30秒に設定し、約1 mLをコーンロータ:R-H1°34’×R24で200秒回転させた後の値を測定した(日本薬局方粘度測定法第2法)。
なお、下表のpHは、保存期間(調液後から3か月目まで)における最高値を示した。
ソフピロニウム臭化物製剤の長期保存試験
試験例3と同様の方法で、下表の実施例5、実施例6、比較例2、及び比較例3を調液し、各種試験に用いた。表中の構成成分と濃度となるように、配合成分を無水エタノールに攪拌・溶解し製剤を得た。本法で製造した各製剤の内容を下表に示す。
pH測定方法、及び粘度測定方法は、試験例3と同様である。
実施例5と実施例6の製剤は、安定性試験1に用いた。下表のpHは、保存期間(即ち、調液してから24か月目まで)における最高値を示した。表中の判定基準は、試験例3と同義である。比較例2は、同様に6か月間保存した。
比較例3の製剤は、安定性試験2に用いた。下表のpHは、保存期間(即ち、調液してから12か月目まで)における最高値を示した。表中の判定基準は、試験例3と同義である。
無水クエン酸濃度が0.001w/w%の比較例3の製剤は、室温下で12か月保存すると顕著に粘度が低下した(-76%)。一方、無水クエン酸濃度が0.05w/w%の実施例5、6の製剤は、調液後のpHが5.2以下に維持されており、粘度の経時的な変動は僅かであった。
したがって、調液してからpHが5.2以下に維持されるソフピロニウム臭化物製剤は、経時的な粘度の低下を抑制することができる。
特に、本試験により、室温で製剤が保存された場合において、調液してから6か月目までのいずれかの時点のpHが2.5から5.2の製剤が好ましいことが明らかとなった。例えば、室温で製剤が保存された場合の、調液してから1か月目、3か月目、又は6か月目のpHが2.5から5.2の範囲内である製剤が好ましい。
実施例5と実施例6の製剤の長期保存試験(25℃±2℃/60%RH±5%RH、遮光)において、調液してから24か月目まで純度試験(類縁物質)を実施した。実施例5において、24か月目にシクロペンチルマンデル酸エチルのHPLCピークがごく僅かに観察された。実施例6においては、調液してから保存期間中に類縁物質の増加及び新たな類縁物質の出現は認められなかった。これらの結果から、実施例5と実施例6の製剤が長期保存試験において安定であることが示された。
