Abstract
Description
本発明は、医薬、とりわけジフェリケファリン又はその薬理学的に許容される塩を含有する透析患者に適用される医薬組成物に関する。 The present invention relates to a medicament, especially a pharmaceutical composition for dialysis patients containing diferikephalin or a pharmacologically acceptable salt thereof.
透析患者におけるそう痒症の原因は十分に解明されておらず、難治性とされている。そう痒症の発現には複数の因子が関与しており、皮膚の乾燥をはじめ、内因性物質の蓄積、ヒスタミンやサブスタンスP等のケミカルメディエータの過剰産生などが挙げられる。さらに、免疫機能の変化やオピオイドバランスの崩壊も原因の一つであり、そう痒症を有する透析患者では、かゆみを誘発するμオピオイド系がかゆみを抑制するκオピオイド系より優位になっていると考えられている。 The cause of pruritus in dialysis patients has not been fully elucidated and is considered intractable. Multiple factors are involved in the development of pruritus, including dry skin, accumulation of endogenous substances, and overproduction of chemical mediators such as histamine and substance P. In addition, changes in immune function and disruption of opioid balance are also factors. In pruritic dialysis patients, the μ-opioid system, which induces itching, is superior to the κ-opioid system, which suppresses itching. It is considered.
透析患者におけるそう痒症の治療には、乳液やクリームといった保湿剤やステロイド剤による外用治療、抗ヒスタミン薬や抗アレルギー薬による外用又は内服治療、広波長の紫外線を用いた光線療法等がある。 Treatment of pruritus in dialysis patients includes topical treatment with moisturizing agents such as milky lotions and creams or steroids, topical or oral treatment with antihistamines and antiallergic drugs, and phototherapy using broad-wavelength ultraviolet rays.
日本では外用治療や内服治療等の既存治療では効果不十分な患者に対し、経口剤のκオピオイド受容体(KOR)作動薬であるナルフラフィン塩酸塩が使用されている。 In Japan, nalfurafine hydrochloride, an oral κ opioid receptor (KOR) agonist, is used for patients for whom existing treatments such as topical and oral treatments are inadequate.
ジフェリケファリンは、海外においてそう痒症の改善薬として開発が行われているペプチド性の新規KOR作動薬である(非特許文献1)。国内においても同様に開発されている。ジフェリケファリンのペプチド構造は、これまでに開発された中枢神経(CNS)作用の低分子ヘテロ環化合物のKOR作動薬と大きく異なっており、その物理化学的性質により膜透過性が低くCNSへの移行は限定的である。そのため、κオピオイド受容体の選択性が高く、他のオピオイド受容体への作用が弱いため、CNSへ容易に移行せず、安全性及び忍容性に優れた薬剤として、早期上市が望まれている。 Differikephalin is a novel peptidic KOR agonist that is being developed as an pruritus-ameliorating drug overseas (Non-Patent Document 1). It is also being developed in Japan. The peptide structure of diferikephalin is significantly different from that of previously developed low-molecular-weight heterocyclic KOR agonists that act on the central nervous system (CNS). migration is limited. Therefore, it has high selectivity for κ opioid receptors and weak action on other opioid receptors, so it does not easily migrate to the CNS and is expected to be marketed early as a drug with excellent safety and tolerability. there is
本件発明は、医療現場における用量調製に伴う人的過誤を低減し、かつ、労力を軽減することができる、ジフェリケファリンを含有する注射用医薬組成物を提供することを課題とする。 An object of the present invention is to provide an injectable pharmaceutical composition containing diferikephalin, which can reduce human error associated with dose preparation in medical practice and reduce labor.
ジフェリケファリン注射剤は、透析終了時の返血時に透析回路より投与する注射剤である。しかし、現在、臨床開発が先行している外国において、ジフェリケファリン注射剤は、医療現場において、個々の患者の体重ごとに1kg単位で厳密に投与量を調整することとされている(非特許文献1)。そのため、用量調製の何らかの過程(例えば、場合に応じて、フリー体換算濃度、体重、希釈度に基づく用量の計算自体や実際の計量など)において、人間がするものとしてミス(インシデント)が不可避的に生じてしまうリスクが存在する。また、そのようなミスが二重三重のチェック体制により十分に防ぐことができるとしても、医療現場において、毎回そのような用量調製を行うことは大変な労力や費用や困難を伴うことになり、結果として、患者の治療に貢献するための投与が敬遠されてしまうことにもなりかねない。 Diferikephalin injection is an injection administered through the dialysis circuit at the time of blood return at the end of dialysis. However, currently, in foreign countries where clinical development is ahead, the dosage of diferikephalin injection is to be strictly adjusted in units of 1 kg according to the body weight of each individual patient in the medical field (non Patent document 1). Therefore, mistakes (incidents) are unavoidable as human beings in some process of dose preparation (for example, dose calculation itself based on free body equivalent concentration, body weight, dilution rate, and actual weighing, etc., depending on the case). There is a risk that Also, even if such mistakes can be sufficiently prevented by a double and triple check system, it would be very laborious, costly and difficult to adjust the dose every time in the medical field. As a result, administration for contributing to the treatment of patients may be avoided.
そこで、医療現場において、個々の患者の体重ごとに1kg単位で厳密に投与量を調整することを不要とし、医療現場における用量調製に伴う人的過誤を低減し、かつ、労力を軽減することができる新規医薬製剤が実現できれば非常に有益である。 Therefore, in the medical field, it is unnecessary to strictly adjust the dosage in units of 1 kg for each patient's weight, reducing human error and labor associated with dosage adjustment in the medical field. It would be very beneficial if a new pharmaceutical formulation that could
しかしながら、実臨床に適したジフェリケファリン医薬製剤の提供には、様々な克服すべき課題が存在する。まず、医療現場に提供される医薬製剤の数(規格数)が医療現場において許容可能でなければならない。また、患者の体重ごとに1kg単位で厳密に投与量を調整しない新規医薬製剤の可能性に関する知見は何ら存在しておらず、有効性・安全性の予測は困難である。したがって、そのような新規医薬製剤を果たして提供することができるのかさえ、不明であった。即ち、新規医薬製剤の用法・用量により、透析患者のそう痒症に対し、有効性及び安全性を有し、かつ各規格間における有効性及び安全性への影響が大きく異ならないことが求められる。 However, there are various problems to be overcome in order to provide diferikephalin pharmaceutical preparations suitable for clinical practice. First, the number of pharmaceutical preparations provided to the medical site (standard number) must be acceptable in the medical site. In addition, there is no knowledge about the possibility of a new pharmaceutical formulation that does not strictly adjust the dosage in units of 1 kg for each patient's body weight, and it is difficult to predict efficacy and safety. Therefore, it was unclear whether such novel pharmaceutical formulations could even be provided. In other words, it is required that new pharmaceutical formulations have efficacy and safety for pruritus in dialysis patients, and that the effects on efficacy and safety between standards do not differ greatly depending on the dosage and administration. .
本発明者らは、まず、ジフェリケファリンの注射製剤の規格数が3~4規格程度とすることができれば、とりわけ本邦の実臨床において好適に適用可能ではないかと着想し、実際に該注射製剤を念頭に本邦の医療機関への丹念なヒアリング結果の解析から、透析領域においては、使い切り型の医薬製剤であり、かつ最大でも3~4規格とすることが望ましいとの知見を得た。そこで、当該規格数を実現可能な医薬製剤について鋭意検討した結果、驚くべきことに特定のドライウェイト区分と規定量のジフェリケファリンを組み合わせた用法・用量により、透析患者におけるそう痒症に対し、有効性と安全性を有し、かつ各ドライウェイト区分間における有効性及び安全性に大きな差が認められないことを発見するに至り、本発明を完成させた。 The present inventors first conceived that if the number of specifications for injection preparations of diferikephalin could be set to about 3 to 4 specifications, it would be particularly suitable for practical application in Japan. Based on analysis of the results of careful interviews with medical institutions in Japan with the formulation in mind, it was found that in the dialysis field, it is desirable to use single-use pharmaceutical formulations with a maximum of 3 to 4 specifications. Therefore, as a result of intensive examination of pharmaceutical formulations that can achieve the standard number, surprisingly, it was found that a combination of a specific dry weight category and a prescribed amount of diferikephalin was effective against pruritus in dialysis patients. , have efficacy and safety, and that no significant difference in efficacy and safety is observed between the dry weight classes, thereby completing the present invention.
本発明は、前記課題を解決するために、一つの態様として、次の構成を有する。 In order to solve the above problems, the present invention has the following configuration as one aspect.

「ドライウェイト」という用語は、血液透析治療において、個々の患者の状態に応じた治療計画の指標として設定される、除水後の目標体重であり、日本透析医学会では「体液量が適正で、透析中に過度の血圧低下を生ずることなく、かつ長期的にも心血管系への負担が少ない体重」を意味する用語として定義されている。すなわち、過剰な体液貯留状態にない体重である。ドライウェイトは、通常医師により決定され、例えば、正常な腎機能を有する患者の排尿後の体重にできるだけ近くなるように設定される。したがって、ドライウェイトは、痙攣等の除水過多に伴う血圧低下症状を示すことなく、血液透析後に安全に到達することのできる最も低い体重を意味することもある。 The term “dry weight” refers to the target body weight after dehydration that is set as an index for treatment plans according to the condition of each individual patient in hemodialysis treatment. , the body weight that does not cause an excessive drop in blood pressure during dialysis and that has a low burden on the cardiovascular system in the long term. That is, body weight without excessive fluid retention. Dry weight is usually determined by a physician and is set, for example, to approximate as closely as possible the post-void weight of a patient with normal renal function. Therefore, dry weight may also mean the lowest body weight that can be safely reached after hemodialysis without exhibiting symptoms of hypotension associated with excessive dehydration such as cramps.
ドライウェイトは、一般に採用されている設定指標に従い設定することができる。指標としては、例えば、透析中の著明な血圧低下がない、透析終了時血圧は開始時血圧より高くなっていない、末梢に浮腫がない、胸部X線で胸水や肺うっ血がなく、心胸郭比が50%以下(女性では53%以下)であるなどが用いられる。 The dry weight can be set according to generally adopted setting indices. Indicators include, for example, no significant drop in blood pressure during dialysis, blood pressure at the end of dialysis not higher than blood pressure at the start of dialysis, no peripheral edema, no pleural effusion or pulmonary congestion on chest X-ray, cardiothoracic A ratio of 50% or less (53% or less for women) is used.
本発明の注射用医薬組成物は、患者のドライウェイト区分に基づいて規定量のジフェリケファリンを投与するために用いられる。これにより、薬剤の毎投与時に体重1kg単位で投与量を調整する複雑な投与方法を回避でき、医療現場における用量調製に伴う人的過誤を低減し、かつ、労力を軽減することができる。本発明において、患者のドライウェイト区分に基づくジフェリケファリンの規定量は、例えば、成人の場合、ドライウェイト45kg未満の患者に対して17.5μg、ドライウェイト45kg以上65kg未満の患者に対して25.0μg、ドライウェイト65kg以上85kg未満の患者に対して35.0μg、ドライウェイト85kg以上の患者に対して42.5μgであり得る。 The injectable pharmaceutical composition of the present invention is used to administer a defined amount of diferikephalin based on the patient's dry weight category. This makes it possible to avoid the complicated administration method of adjusting the dosage in units of 1 kg of body weight each time the drug is administered, and to reduce human error and labor associated with dosage adjustment in the medical field. In the present invention, the prescribed amount of diferikephalin based on the patient's dry weight category is, for example, 17.5 μg for adults with a dry weight of less than 45 kg, and 25.0 μg for patients with a dry weight of 45 kg or more and less than 65 kg. μg, 35.0 μg for patients with dry weights greater than or equal to 65 kg and less than 85 kg, and 42.5 μg for patients with dry weights greater than or equal to 85 kg.

Since the injectable pharmaceutical composition of the present invention is a KOR agonist, it is also used for the treatment of mood swings, improvement of depressive symptoms, postoperative pain, osteoarthritis, and sleep disorders associated with dialysis. be able to.
本発明において、そう痒症の治療効果は、当業者に公知の、対象が感じる痒みの程度をスコア化する評価方法を用いて評価することもできる。例えば、Numerical Rating Scale(NRS)、Visual Analogue Scale(VAS)、白取の重症度基準、Skindex-10、Skindex-16、5-D Itch Scale、Patient Global Impression of Change(PGIC)等が挙げられる。 In the present invention, the therapeutic effect of pruritus can also be evaluated using an evaluation method known to those skilled in the art that scores the degree of itching felt by a subject. Examples include Numerical Rating Scale (NRS), Visual Analogue Scale (VAS), Shiratori severity criteria, Skinindex-10, Skinindex-16, 5-D Itch Scale, and Patient Global Impression of Change (PGIC).
最も代表的な指標であるといえるNRSは、1日の中で最も強く感じたかゆみに対して、「かゆみなし」を0、「考えられる最大のかゆみ」を10として、0から10までの整数で評価する。一般に、NRSは、1以上4未満が軽度、4以上7未満が中等度、7以上が高度のかゆみと評価される。VASは、100mmの線の左端を「かゆみなし」、右端を「考えられる最大のかゆみ」として、1日の中で最も強く感じたかゆみの程度を表す位置に印を付け、線の左端からの長さを測定して評価する。NRSとVASの評価は相関性が認められるが、より簡便な評価方法としてはNRSである。かゆみに対するNRSスコアは、そう痒症の評価方法として臨床試験で広く使用されている。 The NRS, which can be said to be the most representative index, is an integer from 0 to 10, with 0 representing "no itch" and 10 representing "maximum possible itch" for the most intense itching felt during the day. Evaluate with In general, an NRS of 1 or more and less than 4 is rated as mild, 4 or more and less than 7 is moderate, and 7 or more is rated as severe. On the VAS, the left end of the 100 mm line was designated as “no itch” and the right end was designated as “maximum possible itch”. Measure and evaluate the length. There is a correlation between the evaluation of NRS and VAS, but NRS is a simpler evaluation method. The NRS score for pruritus is widely used in clinical trials as a measure of pruritus.
白取の重症度基準は、「症状なし」から「激烈な痒み」までをそれぞれ0から4までのスコアとして、日中及び夜間のそれぞれの症状を被験者自身で判定し、評価する。白取の重症度基準は、国内の皮膚科領域でかゆみの程度を評価する際に汎用されており、日常生活への影響を重症度判断の基準として用いている。 The severity scale of Shiratori is based on scores from 0 to 4 ranging from "no symptoms" to "severe itching", and each symptom during the day and at night is judged and evaluated by the subject himself/herself. Shiratori's severity criteria are widely used in evaluating the degree of itching in the domestic dermatology field, and the impact on daily life is used as the criteria for determining severity.
Skindex-16は、「まったく悩まされなかった」から「いつも悩まされた」までをそれぞれ0から6までのスコアとして評価する。Skindex-16は、皮膚疾患に関連するQOL 評価に応用されている。 The Skindex-16 rates "never bothered" to "always bothered" as scores from 0 to 6, respectively. Skindex-16 has been applied to QOL evaluation related to skin diseases.
5-D Itch Scaleは、かゆみの5つの構成要素(持続、程度、傾向、悪影響、分布)を判定する。 The 5-D Itch Scale measures five components of itch: duration, extent, tendency, adverse effects, and distribution.
PGICは、かゆみの全般的症状を「非常に良くなった」、「良くなった」、「少し良くなった」、「変わらなかった」、「少し悪くなった」、「悪くなった」及び「非常に悪くなった」の7段階で評価する。 The PGIC rated global symptoms of itch as "much better", "better", "slightly better", "no change", "slightly worse", "worse" and " It has become very bad."
薬剤のかゆみに対する有効性は、上記評価方法においてスコアの変化量を評価することにより確認することもできる。具体的には、薬剤の投与前(ベースライン)のかゆみの程度と、薬剤の投与後のかゆみの程度を比較して、かゆみの程度が改善している場合、かゆみが減弱されていると評価することもできる。本発明において、かゆみに対する有効性は、患者のQOLを向上させるという観点において、NRSもしくはVASスコアの改善に加えて、QOLスコア(白取の重症度基準、Skindex-16、5-D Itch Scale、PGIC)の改善をも認められることが好ましい。 The effectiveness of the drug against itching can also be confirmed by evaluating the amount of change in the score in the evaluation method described above. Specifically, the degree of itching before drug administration (baseline) is compared with the degree of itching after drug administration, and if the degree of itching improves, it is evaluated as being attenuated. You can also In the present invention, from the viewpoint of improving the patient's QOL, the efficacy against itching is evaluated in addition to the improvement of the NRS or VAS score, as well as the QOL score (Shiratori severity criteria, Skinindex-16, 5-D Itch Scale, PGIC ) is also preferably observed.
本発明において、本発明の注射用医薬組成物の有効性・安全性は各ドライウェイト区分間において著しい差が認められないことが好ましい。具体的には、いずれのドライウェイト区分においてもそう痒症の改善効果が認められるか、透析前トラフ値(投与直前の血漿中薬物濃度(血漿中ジフェリケファリン(未変化体)濃度))に大きな変動が認められない、またはその両方を満たすことが好ましい。ジフェリケファリンの血漿中濃度は、一般的な手法により測定することができるが、例えば、LC-MS/MS法により測定することができる。 In the present invention, it is preferred that no significant difference in the efficacy and safety of the injectable pharmaceutical composition of the present invention is observed between the dry weight classes. Specifically, whether any improvement in pruritus is observed in any dry weight category, pre-dialysis trough value (plasma drug concentration immediately before administration (plasma diferikephalin (unchanged drug) concentration)) It is preferred that no large fluctuations are observed in or both are satisfied. The plasma concentration of diferikephalin can be measured by a general method, for example, by an LC-MS/MS method.
