Abstract
本發明系有關於用於在人或其他動物中治療乾眼病、或者診斷、治癒、減輕、治療或預防乾眼綜合症的眼用組合物和方法。
Description
本申請要求於2011年10月6日提交的美國臨時專利申請序列號61/544,151之權益,所有公開內容通過該特異引用併入本文。
本發明系有關於用於在人或其他動物中治療乾眼病、或者診斷、治癒、減輕、治療或預防乾眼綜合症的眼用組合物和方法。
乾眼病是眼淚和眼睛表面的多因數疾病,其導致不適、視力障礙和對於眼睛表面具有潛在損害的眼淚膜不穩定的症狀。正常的淚膜是相對穩定的,薄膜由表面液層和與粘液膠層混合的水性層構成,該凝膠層部分粘附至角膜和結膜表面上皮組織。天然淚膜對於眼睛的折射表面的潤滑和維持是重要的。乾眼綜合症是複雜疾病,其特徵在於淚膜的一種或多種組分的失調,從而導致失去淚膜穩定性、淚膜滲透壓平衡的高滲偏移、和/或眼睛表面上流體的量不足。這由下列表徵:淚膜的快速破裂以及大量症狀,包括灼燒感/刺激感、異物感、瘙癢和畏光。
大部分患有乾眼綜合症的患者開出人工淚液的處方或推薦使用人工淚液。此外推薦眼瞼壓迫和擦洗,並且添加必要的脂肪酸至飲食。
乾眼綜合症是源自下列中的一種的正常淚膜的常見疾患:淚液產生減少、過度眼淚蒸發、淚層中通常發現的粘液或液體的產生異常。
水性(水的)眼淚缺陷由水的眼淚的較差產生或水的淚層的過度蒸發而引起。
由淚腺較差產生眼淚可源自年齡、激素改變或各種自身免疫疾病,例如原發性乾燥綜合征、類風濕性關節炎或狼瘡。
水的淚層的蒸發損失通常源自不充分的重疊脂質層。一些藥物例如抗組織胺類、抗抑鬱藥、β-阻斷劑和口服避孕劑可降低眼淚產生。如果眨眼降低或如果眼瞼不能閉上,因為淚液蒸發眼睛可乾燥。
閱讀、觀看TV或實施要求眼睛緊密關注的任務可以減少眨眼、允許淚液的過度蒸發。
在它們滲透眼睛的表面並降低角膜神經敏感性後,LASIK和其他視覺矯正工序可引起乾眼病。此後,眼睛無法傳感潤滑的需要並且不足的淚液產生結果。
已經發現治療眼睛的新型眼用組合物和治療乾眼病的方法。

完全臨床研究的目的為評價兩種候選物的安全性、效果和可接受性:製劑A和製劑B與Allergan的現有OPTIVETM滴眼液在具有乾眼病的跡象和症狀的受試者中進行比較。
結果顯示,製劑A和製劑B在具有乾眼病的跡象和症狀的受試者中是臨床安全和有效的。
製劑A是多劑量(MD)製劑,含有:聚山梨酯80,羧甲基纖維素鈉,甘油,Purite®,硼酸,PemulenTM
TR-2,蓖麻油,赤蘚醇,左旋肉堿,氫氧化鈉和注射用純化水,以15 ml多劑量瓶來供應。溶液在具有乾眼病的跡象和症狀的受試者中是臨床安全和有效的。
製劑B時單位劑量(UD)製劑,含有:聚山梨酯80,羧甲基纖維素鈉,甘油,硼酸,PemulenTM TR-2,蓖麻油,赤蘚醇,左旋肉堿,氫氧化鈉和注射用純化水,以0.4 ml單位劑量安瓶供應。溶液在具有乾眼病的跡象和症狀的受試者中是臨床安全和有效的。
該研究是多中心單盲隨機活性對照4-臂平行組研究,其設計來比較製劑A和OPTIVETM潤滑滴眼液多劑量(OPTIVE MD)以及製劑B和OPTIVETM敏感無防腐劑潤滑滴眼液單位劑量(OPTIVE UD)的安全性、效果和可接受性。
對照溶液OPTIVETM潤滑滴眼液多劑量(OPTIVE MD)含有:羧甲基纖維素鈉,甘油,硼酸,硼酸鈉,檸檬酸鈉,氯化鉀,左旋肉堿,赤醇,氯化鈣,氯化鎂,Purite®,純化水和氫氧化鈉以調節pH至7.3,以15 ml多劑量瓶供應。
對照溶液OPTIVETM敏感無防腐劑潤滑滴眼液單位劑量(OPTIVE UD),含有:羧甲基纖維素鈉,甘油,硼酸,硼酸鈉,檸檬酸鈉,氯化鉀,左旋肉堿,赤醇,氯化鈣,氯化鎂,注射用純化水和氫氧化鈉以調節pH至7.3,以0.4 ml單位劑量安瓶供應。
研究的時間為每個受試者30天,並且由至多3個
規定訪問(1天[基線],7天和30天[離開])構成。在1天,具有乾眼病的跡象和症狀的由條件的受試者根據2:2:1:1治療分配比例來分配,以分別使用製劑A,OPTIVE MD,製劑B或OPTIVE UD。
約300名受試者登記在USA內13至14個位點,以具有288個完成的受試者,假設退出率為約5%。為了登記在研究中,各受試者不得不滿足某些納入標準,並且不滿足排除標準。
根據需要,指導受試者在各眼睛中滴注1至2滴它們分配的研究產品,但至少每天至少2次,30天。在任何時間受試者可以從研究中主動退出。另外,通過下列原因研究者可以停止使用受試者的研究:例如副作用、損失後續步驟、違反協定或缺少效果。
受試者隨機分配製劑A,OPTIVE MD,接受含有2個多劑量瓶(各瓶15 mL)的研究產品的試劑盒,並且指導使用1瓶直到其是空的,然後使用第二瓶。
受試者隨機分配製劑B和OPTIVE UD,接受含有180個單位劑量安瓶(各安瓶0.4 mL)的研究產品的試劑盒,並且對於雙眼每個劑量指導使用1個安瓶。
根據需要,在各眼中每個受試者指導滴注1至2滴研究產品,但整個研究期間至少每天2次(在隨機化後從1天至30天,之後離開研究)。
受試者和所有調查位點人員被掩蔽研究治療。為了保持產品掩蔽,製劑B和OPTIVE UD滴設置在相同0.4
mL單位劑量安瓶中,而製劑A和OPTIVE MD滴設置在相同15 mL多劑量瓶中。
在準備治療(ITT)群在30天主要效果測量是眼睛表面疾病指數©(OSDI)問卷。OSDI問卷包括12個問題,5-點評級(0=零次數;1=一些次數;2=一半次數;3=大部分次數;4=所有次數;一些問題可能是“N/A”[不適用]應答)(Schiffman et al,2000)。受試者被詢問來使用5點評級以評價各種症狀的頻率、相關視覺功能和乾眼病的環境引發劑。在研究訪問之前的最後星期,受試者被詢問來基於它們的症狀頻率來進行評價。總體而非每眼來評價該情況。
通過2-因素方差分析(ANOVA)模型,具有治療和基線OSDI分層法作為主要效果,在30天以OSDI得分進行主要效果分析從基線的變化。末次觀測值結轉(LOCF)用於歸因於遺失資料。使用2-側置信區間(CI)測試非劣性。基於ANOVA模型,計算製劑B和OPTIVE UD(製劑B減去OPTIVE UD)之間在30天以OSDI得分從基線改變的處理差異和95% CI。如果95% CI的上限小於7.3的預定邊緣,建立非劣性。
滿足主要效果端點。在30天,製劑B和OPTIVE UD組之間以OSDI得分(95%置信區間[-5.42,2.51])在ITT群中從基線平均改變中,沒有觀察到統計上顯著性差
異。如通過以OSDI得分從基線改變而測量的,在降低幹眼症狀的嚴重性方面,製劑B不劣於OPTIVE UD製劑。
類似ITT群,在30天,預方案(PP)群的製劑B和OPTIVE UD組以OSDI得分(95%置信區間)從基線的平均改變中,沒有觀察到統計上顯著性差異,訪問是(-5.72,2.37);上限低於7.3的臨床相關邊緣。
在所有4個治療組,對於ITT和PP群,在7天和30天訪問,以OSDI得分從基線的平均改變存在統計上顯著性差異(p<0.001)。
在30天,在以OSDI得分從基線的平均改變方面,製劑B組不劣於製劑A組。
總的來說,製劑B和OPTIVE UD組、製劑B和製劑A組、或製劑A和OPTIVE MD組之間沒有統計上顯著性差異。
該研究結果證實,在降低中等至嚴重乾眼病的受試者的幹眼症狀的嚴重性方面,製劑B不劣於OPTIVE UD製劑。
製劑B在研究過程中顯示良好耐受。在整個研究中,不存在治療相關的嚴重的副作用。安全性性能一致於OPTIVE UD,OPTIVE MD和製劑A。在臨床應用中,
其優於製劑B的安全性,並且證實製劑A的安全性。
包括的次要效果測量(眼淚破裂時間)TBUT、角膜染色、結膜染色和Schirmer試驗。
在2分鐘等待角膜染色期間,在各眼中測量TBUT(單位秒)3次。將供應於研究的螢光素施加至優異球結膜。該1滴的螢光素鈉用於TBUT和角膜染色。然而,如果需要,在TBUT後螢光素可以重新施加至角膜染色。進行檢查,使用10X放大倍數的裂隙燈,利用鈷藍照射和屏黃光濾色器。在各眼進行三次連續TBUT,並且所有三個測量使用提供的跑錶來計時。
在所有其他眼用試驗之後,在各眼中進行Schirmer試驗(使用麻醉)。一滴麻醉劑滴注,並且在滴注後精確地開始4分鐘試驗。在暗光室中進行試驗。儘管受試者向上看,但是下眼瞼輕柔地向下和臨時拉伸。無菌條的彎圓端鉤住各眼中下眼瞼邊緣的臨時和中間三分之一的關節上的低結膜囊。在5分鐘後,淚液前端被掩蔽,並且在各無菌條上測量。
這些測量的原始數值概括用於ITT群,其中在各規化的隨後訪問使用LOCF遺失資料歸因。計算處理比較之間的處理差異和95% CI。在30天,在製劑B和製劑A、製劑A和OPTIVE MD之間以OSDI得分從基線改變中處理差異和95% CI也作為次要效果變數分析。
在TBUT,角膜染色,結膜染色和Schirmer試驗
的次要效果測量方面,製劑B組不劣於OPTIVE UD和製劑A組。
當前研究的目的是在具有乾眼病的跡象和症狀的受試者中評價製劑B的安全性、效果和可接受性。進行該研究以比較製劑B和現有OPTIVE UD製劑,以及比較製劑A。在該研究中滿足主要效果端點。
在30天,以OSDI得分從基線的平均改變製劑B組和對照OPTIVE UD組之間沒有差異。如由OSDI問卷測量的,在降低幹眼症狀的嚴重性方面,製劑B製劑不劣於OPTIVE UD和製劑A。儘管在主要效果測量和總體分析和子組分析(OSDI階層)中製劑B和製劑A組之間存在統計上顯著性差異,從而支持製劑B組,但是研究不設計以在兩組之間測試統計上的優異,因此關於製劑B對製劑A優異的牢固結論不能建立。因為這是4-臂研究,還進行製劑A和OPTIVE MD製劑之間的效果比較。總的來說,製劑A和OPTIVE MD製劑之間的效果沒有差異。
製劑B製劑顯示出具有可接受的安全性性能。
效果:該研究的結果證實,在具有中等至嚴重乾眼病的受試者中降低幹眼症狀的嚴重性方面,製劑B製劑不劣於OPTIVE UD製劑。
在不同研究中,顯示製劑B降低淚液蒸發,因此有助於淚膜穩定性,並且在應該發生高滲偏移的條件下保
護淚膜滲透壓平衡。製劑B在具有和沒有乾眼綜合症的受試者中降低蒸發。
下列非限制性例子示出本發明之進一步某些方面:
製劑B的滴眼液施用至患者眼睛,患者為高加索人,52歲男性並患有大致乾眼病。在每眼每天兩次施用滴眼液兩天后,患者感受乾眼綜合症降低。
一滴製劑A施用至患有乾眼病的患者的各眼,一天1至3次。在兩天后,患者感受乾眼綜合症降低。
應該理解,本文公開的實施例示出申請專利範圍的原理。可以使用的其他變化在申請專利範圍的範圍內。因此,通過例子而非限制,可以依照本文教導使用可替換的實施例。因此,申請專利範圍不限於前面所示和描述的實施例。
