Description

包含酸碱中和组合的药物组合物及其应用 技术领域
本申请公开涉及一种酸碱中和组合作为局部活性成分在制备用于治疗局部病变疾病的局部药物中的应用、以及包含该组合的局部药物组合物、和一种治疗局部病变疾病的方法。
背景技术
由于有大量研究工作支持,实体肿瘤常被用作局部病变疾病、尤其是难治性局部病变疾病的研究模型。实体肿瘤是一种具有瘤体征状的肿瘤疾病,瘤体是包含有肿瘤细胞的一种特征性病变组织。以胰腺癌瘤体为例,胰腺癌细胞在其中仅占约30%的体积比。可见,除了肿瘤细胞,瘤体组织中往往还存在更大量的其它组成(有时亦被称作肿瘤细胞的微环境),包括其它多种细胞、多种细胞间质、多种管道等。
局部给药具有将药物进行物理靶向的优点。于是曾经有人认为,细胞毒药物的局部给药可以提高其瘤内浓度、从而提高其疗效。然而,局部给药细胞毒药物却并未显示出疗效的明显提高。仅仅提高其瘤内浓度,似乎尚不能明显提高其靶向瘤内组织中癌细胞的效率。除了求助于其缓释形式以外,细胞毒药物在临床上几乎仍全身给药。化学消融剂(高纯度乙醇、高浓度酸碱)不以细胞破坏而以组织破坏为特征。与细胞毒药物相比,其几乎无靶向癌细胞的全身疗效,却往往显示出局部疗效。对于酸碱化学消融剂而言,其极端的酸性/碱性更是被认为是它们的作用基础。然而,它们通常是不能对靶组织和其它组织作足够区别的強破坏剂,使得它们的局部刺激作用很强,低效率高刺激性使得它们的实际应用有限。因而,近十年来化学消融剂以经从恶性实体肿瘤临床上淡出。实际上,目前临床上以几乎没有局部安全性和局部疗效均高的局部药物。
因而,仍然需要开发新的治疗诸如实体肿瘤的局部病变疾病的药物、尤其是局部药物,以满足现有技术尚不能满足的各种临床需求。实际上,其它局部病变、尤其是顽固性局部病变疾病的防治也都有这个急迫需要。
发明内容

根据本发明的再一个方面,其提供一种用于治疗局部病变疾病的局部药物组合物,其包含可作为局部活性成分的酸碱中和组合以及所述中和组合的局部协同物,其中所述酸碱中和组合包含酸化剂及其pH中和剂、或碱化剂及其pH中和剂,且其中所述酸化剂为选自强酸或弱酸之一种或多种;所述碱化剂为选自弱碱或强碱之一种或多种;所述pH中和剂为选自可使得所述酸化剂或碱化剂趋于pH中性化的酸碱性物质,以及其中所述酸化剂、碱化剂、和pH中和剂优选为选自可用作pH调节剂而非用作治疗局部病变疾病的常规活性组分的酸碱性物质。
在一些实施方式中,本发明的组合物还包括药物学可接受的载体,例如水性载体或醇类载体,优选地为水。在一些实施方式中,本发明的组合物可以被制备为注射剂的剂型,所述注射剂包括液体注射剂和注射用粉针剂。
根据本发明的又一个方面,其提供一种治疗局部病变疾病的方法,其包括向有此需要的个体的局部病变区施用治疗有效量的可致靶区组织坏死的药物组合物,该药物组合物包含可作为局部活性成分的酸碱中和组合以及任选存在的所述中和组合的局部协同物,其中所述酸碱中和组合包含酸化剂及其pH中和剂、或碱化剂及其pH中和剂,且其中所述酸化剂为选自强酸或弱酸之一种或多种;所述碱化剂为选自弱碱或强碱之一种或多种;所述pH中和剂为选自可使得所述酸化剂或碱化剂趋于pH中性化的酸碱性物质,以及其中所述酸化剂、碱化剂、和pH中和剂优选为选自可用作pH调节剂而非用作治疗局部病变疾病的常规活性组分的酸碱性物质。
根据本发明的实施方案与现有技术中的酸碱型化学消融剂相比具有以下优点:更高的特异性、有效性和安全性。
根据本发明的实施方案与现有技术中的包含酸碱型化学消融剂的药物组合物相比具有以下优点:更高的特异性、有效性和安全性。
根据本发明的实施方案与局部病变疾病治疗的现有技术相比具有以下优点:与现有细胞毒药物相比,显示出几乎无毒的全身安全性和明显较高的局部病变疗效;与现有分子靶向药物相比,显示出不那么苛刻的适应症筛选,以及针对快速生长瘤体、大瘤体和乏血供瘤体的巨大潜力。本发明的应用和组合物也不受现有细胞毒性药物和现有分子靶向药物遭 遇的耐药性问题的困扰。此外,该应用和组合物制备方便、成本便宜,特别有助于使难以承受高额费用的广大人群也享受到安全、有效治疗。
具体实施方式
按照现有技术的教导,局部病变中的pH升高是碱化剂(例如氢氧化钠)作为化学消融剂的药理基础。本发明的发明人在进行碱化剂的化学消融研究中,将pH低得多的碳酸氢钠作为pH中和剂与氢氧化钠混合以将该酸碱中和组合物(3%氢氧化钠/7%碳酸氢钠)作为阴性对照物。按照现有技术的披露推测,碳酸氢钠加入氢氧化钠溶液使其中性化后,药效将随pH降低(例如从pH12降至10.0)而降低。然而,意外的是,低pH组合物(酸碱中和组合物)显示出比高pH氢氧化钠明显提高的抑瘤率(例如从43%升至68%)。于是,本发明的发明人研究了药学上允许的酸碱中和组合物,以及进一步研究了包含该酸碱中和组合及其局部协同物的药物组合,以及它们的应用。

以下实施例中所用的实验动物均为通过专业实验动物公司购入,均为SPF(Specific Pathogen Free,无特定病原体)级动物。以小鼠为例,共有2种:BALB/c小鼠、裸小鼠,其中裸小鼠为裸基因(nu)导入BALB/c小鼠获得的突变系(BALB/c-nu)小鼠。小鼠均为6-8周龄健康雌性、体重17.5-20.5g。
皮下移植细胞生成局部病变(如瘤体)的动物建模为现有技术,当瘤体长至所需体积(如小鼠荷瘤为50-500mm 3)时为建模成功,建模后将动物分成若干组,每组6只,定期观察测定一般状态、体重、摄食量、动物移植物抗宿主病、瘤体体积、瘤重、生存时间等。优选的,所述局部病变的模型分别含肿瘤细胞的瘤体(代表瘤体)、含成纤维细胞的结节(代表含成纤维细胞的瘤体和其它局部病变)、正常活组织(代表含普通组织的局部病变)。
局部病变(例如瘤体)体积(V)、相对局部病变(例如瘤体)增殖率(R)、局部病变(例如瘤体)抑制率(r’)、抑瘤率(r)分别按照下述公式计算:
局部病变(例如瘤体)体积V=0.5×a×b 2,其中a、b分别代表局部病变的长、宽;
相对局部病变(例如瘤体)增值率R=TRTV/CRTV×100,其中TRTV和CRTV分别为研究组和阴性对照组的局部病变体积;
相对局部病变(例如瘤体)体积=V t/V 0,其中V 0、V t分别代表分组后给药第一天和给药第t天的瘤体体积;
局部病变(例如瘤体)抑制率(r’)=100%-R,其中R为瘤体增殖率。
抑瘤率r=(CW-TW)/CW×100%,其中TW、CW分别为研究组、阴性对照组的平均瘤重。
在下述实施例中,药物i的药效记为Ei,可以用ri’或ri表示。药物的作用类型即药理可通过药效,尤其是同意药物在不同方案中的药效来研究。如当药物i在方案X、Y之间的药效差异不大时(如Ei X/Ei Y<200%),其说明药物的药理是相同的;当药物i在方案X、Y之间的药效差异很大时(如Ei X/Ei Y>200%),说明药物i在方案X中的药理大大超过了其在方案Y中药理的动力学预期范围,很可能涉及与方案Y不同的新药理。若两个药物显示出显然不同的Ei X/Ei Y关系,则很可能涉及不同的药理;若两个药物显示出相似的Ei X/Ei Y关系,则它们很可能涉及相同的药理,至少涉及相似的药理,如类化学消融药理和化学消融药理。
在以下实施例中,实验结果(例如瘤重、瘤体积、病变组织体积)采用均数±标准差(x±s)表示,两个实验动物组与组均数之间的差别采用统计学软件SPSS13.0或SPSS19.0进行显著性检验,检验选用统计量t来进行,检验水准α=0.05,P<0.05表示差异有统计学意义,P>0.05则无统计学意义。
化疗的阳性对照包括经典的细胞毒药物(如0.5-1%5-氟尿嘧啶,其在下述实施例条件下的抑瘤率为≥30%)和经典化学消融剂(如75-99%乙醇,其在下述实施例条件下的抑瘤率为≥15%)。免疫增强阳性对照包括细胞因子(如白细胞介素-12,)、细菌组分(如减毒细菌疫苗等)、疫苗佐剂等免疫增强剂。
在本发明的范围内,A药和B药的组合物记为B/A,其共用作用通过q=实际共用作用/理论单纯相加预期作用判断进行,其中A、B的单用药效分别记为E A和E B,如如抑瘤率,A/B的实际共用药效记为E A+B。当q=1时说明实际共用作用符合理论预期,显示为相加作用;当q<1时说明实际共用作用弱于理论预期,显示为拮抗作用;当q>1时说明实际共用作用超理论预期,显示为协同作用。
判断动物实验中合并用药效应的方法有Burgi法(Burgi Y.Pharmacology;Drug  actions and reactions.Cancerres.1978,38(2),284-285)。金正均对Burgi法进行了改进(金正均,等概率和曲线和“Q50”,上海第二医学院学报;1981,1,75-86),其q计算式为:q=E A+B/(E A+E B-E A×E B)。在本发明以下实施例中,根据金正均法的实际药效/预期药效比q进行的药物A和药物B联合给药的共用药效作用判断如下:
当药物A和药物B的组合物组并不显示有意义的药效((例如r或r’≤15%)时,该联合给药也就未显示有意义的共用作用,在本发明中视作可忽略不计的共同作用。当组合物组显示有意义的药效(例如抑瘤率>15%)时,如果实际药效/预期药效比q=1.00,则该组合物的共用药效作用为药效相加作用(实际作用符合理论单纯相加预期);如果实际药效/预期药效比q>1.00,则该组合物的共用药效作用为明显药效协同作用(实际作用超理论单纯相加预期);如果实际药效/预期药效比q<1.00,则该组合物的共用药效作用为明显药效拮抗作用(实际作用不及理论单纯相加预期)。
实施例1:药物组合物的制备
按照上述本发明的药物组合物的制备方法,可以配制出本发明众多不同的局部药物组合物。以下列出本发明的药物组合物的制备试验的几个例子。
1、液体注射剂的制备
按所需浓度量取药物组合物中的必要组成(例如碱化剂3g氢氧化钠、pH中和剂7g碳酸氢钠)、任选存在的其他组分及以及定容至总体积(例如100ml)的液体载体(例如注射用水),并将它们缓慢混合均匀,除菌过滤后分装为所需量(例如10ml/瓶)储存备用。该制备物(例如7%碳酸氢钠/3%氢氧化钠水溶液)可作为液体药物局部给药。
2、注射用粉针剂的制备
按所需浓度量取药物组合物中的必要组成(例如碱化剂3g氢氧化钠、pH中和剂7g碳酸氢钠)、任选存在的其他组分及以及定容至总体积(例如100ml)的液体载体(例如注射用水),并将它们缓慢混合均匀,除菌过滤后分装为所需量(例如10ml/瓶)进行冷冻干燥及压塞、轧盖,制备为除菌干粉备用。
按各组分所需浓度将所需量的除菌干粉(例如1瓶上述干粉)复溶于所需量的除菌液体(例如注射用水)为所需复溶液(例如7%碳酸氢钠/3%氢氧化钠水溶液)后即可作为液体药物局部给药。

实施例2:组合物的协同性研究
在一个系列试验中,分别研究了药物的抑瘤效应、刺激性和致组织坏死。
在抑瘤效应研究试验中,成功建模的试验动物(荷肉瘤S180细胞小鼠,瘤体平均体积314mm 3)随机分为2个阴性对照组(01、02)和9个药物研究组(1-9)。阴性对照物为生理盐水,研究药物如下表所示。药物均为水溶液,按实施例1的制备方法配置而成。阴性对照物、研究药物分别行腹腔注射(02、6、9组)和行瘤内注射(其它研究组)。各组均每3日用药一次,一共3次,注射量150ul/只。用药结束后5日,对动物进行安乐死,解剖后测定瘤重,并从阴性对照组计算抑瘤率,结果示于下表。
在刺激性研究试验中,小鼠30只,雌雄不限,随机分为5组(下表中的1、3、4、7、8组),每组6只。各组实验动物均在右腿股四头肌注射100ul如下表所示的研究药物。注射24h后,对动物安乐死,观察注射部位的充血、水肿、变性、坏死等现象的程度进行刺激反应评分。评分标准以阴性对照组现象为0分、3%NaOH组现象为5分为基础进行计算。刺激反应评分的结果示于下表。
在组织坏死研究试验中,新西兰大白兔30只,体重2.0-2.5kg,雌雄不限。随机将实验兔分为5组(下表中的1、3、4、7、8组),每组6只。首先于实验兔耳缘静脉注射麻醉剂麻醉,再将之仰卧位固定于兔架上,于无菌条件下行偏右侧小切口开腹,暴露肝脏,然后将22G的PTC针穿刺进入肝脏最厚实的肝右叶中心,针尖距离穿刺点肝包膜的深度为1.5cm,分别匀速缓慢注射研究药物。每只大白兔行一次肝内注射,注射1.0mL如下表所示的研究药物。兔子用药后以常规饲料饲养,1周后处以安乐死,解剖后测定肝脏坏死区。沿坏死区中央切开肝脏,坏死区范围以最大层面为准,分别测量坏死区最大直径及最小直径。肝组织坏死区平均直径=(最大直径+最小直径)/2。肝组织坏死区平均直径的结果示于下表。

通常认为,同一组合物在B技术方案中的抗肿瘤药效超过A方案中的药效动力学提高预期极限(一般为<150%,或从无作用变为有效作用,或瘤重差异有统计学意义),就很可能是不同药理的药物效应。
在上表的抑瘤效应结果中,在腹腔注射系列中,组合物研究组6和9各自与阴性对照组(02组)的瘤重差异均无统计学意义(均为p>0.05),且它们的抑瘤率均低于常规的有效抑瘤标准(40%)。出人意料的是,使用相同的组合物,研究组4的抑瘤率比研究组6高出20倍以上,研究组8的抑瘤率比研究组9高出40倍以上。于是,通过完全不同的药物效应,相同组合物不同用药方式显示出明显不同的靶向和药理。经不同方式给药(腹腔注射和局部给药)后,同一给药组成的组合物的靶区(局部病变)组成可能完全不同。腹腔注射的组合物进入血液再到达局部病变处,其给药组成以完全被血液稀释甚至消解(例如不同组成在某些器官的不同滞留)。而局部给药的组合物的靶区组成则与其给药组成相同(至少在一段时间内)。換言之,经不同方式给药的组合物应当有不同的组成特征以获得协同药效。
在现有技术中,局部给药的高于某一浓度阈值的碱和酸(例如氢氧化钠、碳酸钠、碳酸氢钠、乙酸、盐酸)可作为化学消融剂使用。化学消融剂的pH的两极化(趋于0或趋于14)被认为是其化学消融作用的正相关因素。因而,常规化学消融剂的pH选择通常为≤2%(例如50%乙酸、25%盐酸)、或≥11.5%(例如7%氢氧化钠)。在这种极端pH条件下,强烈的无差别组织破坏被认为是常规化学消融剂的药理作用基础。通常认为,化学消融剂对正常组织的破坏越大,则对病变组织的破坏也越大。很多化学消融剂的筛选,便是通过对正常组织(例如肝组织)的破坏来进行的。在上表中,单药研究组1、2的结果与现有技术的认识一致:刺激反应评分越高,则肝组织坏死面直径越大,而抑瘤效应也越高。
于是,使得酸化剂或碱化剂的pH趋于中性化的pH中和剂的加入理应显示出对组织破坏的拮抗作用、而非协同作用。7%碳酸氢钠(pH6.9)的加入使得3%氢氧化钠(pH11.8)的pH下降1.6,该组合物明显中性化(7%碳酸氢钠/3%NaOH,pH10.2)。研究组4与1比较,它们的刺激反应评分和肝组织坏死面直径的确如所预示地降低,组合物组显示出局部刺激拮抗作用和正常组织破坏拮抗作用。然而在上表中,研究组4与1比较,其抑瘤率却大于后者。在研究组4、3、1之间,组合物组4的q=1.11>1.00,且其分别与3组和1组间的剩余瘤重差异有统计学意义(均为p<0.05),于是显示出明显协同药效。这些结果说明,pH 更中性的物质的加入可能使得组合物显示出较高的组织破坏特异性,从而降低局部刺激风险显示出协同安全性、甚至可以同时提供协同药效。
这个不大合乎通常看法的现象(酸化剂或碱化剂的pH趋于中性化的组合物显示出针对病变组织的协同药效、甚至是明显协同药效)的出现,显然必须一个不大通常的技术方案。在上表中,在局部给药系列中,尽管各组合物的组分量比相同,组合物研究组5的抑瘤率仅为组合物研究组4的47%(32%:68%),且两组的瘤重差异有统计学意义(p<0.05)。在研究组5和2之间,它们的抑瘤率均未达到40%的通用标准、且剩余瘤重差异无统计学意义(p>0.05),于是并未显示出协同药效。研究组5和4所用的组合物的组分及其量比相同,但酸化剂或碱化剂以及它们各自的pH中和剂的浓度不同,导致了共用效应的不同。这些结果进一步说明,要获得协同药效,不同方式给药的组合物可能必需完全不同的组成要素。全身给药的组合物通常要求组分量比即可(它们反正是要进入血液稀释的),而局部给药的组合物仅给出组分量比显然不行,还必须给出其它特征(例如浓度)。
此外,在上表的刺激反应和组织坏死结果中,15%精氨酸/7%碳酸氢钠/3%NaOH比7%碳酸氢钠/3%NaOH的pH略有提高,然而15%精氨酸的加入却使得刺激反应评分和肝组织坏死面直径降低,显示出局部刺激拮抗作用和正常组织破坏拮抗作用。然而,在研究组8、7、4之间,组合物组8的q=1.15>1.00,且其分别与7组和4组间的剩余瘤重差异有统计学意义(均为p<0.05),于是显示出明显协同药效。这些结果说明,新的局部协同物的加入可以通过改变组合物性质(也许例如提高缓冲容量)使得组合物显示出更高的药效、甚至是协同药效。
总之,本发明的组合物在局部给药时似乎显示出与全身给药明显不同的药理。例如,其主要药理并非以分子形态分布至血液中去攻击病变组织内的病原体(例如瘤体内的肿瘤细胞)、而是在给药处以药液形态分布至组织间隙去攻击病变组织(例如瘤内组织)
根据上述研究及更多的类似研究,可以得出本发明的组合物作为局部活性成分在制备用于治疗局部病变疾病的局部药物中的应用技术方案的必要条件为:
本发明的药物组合物的组成必须使得其可以局部给药、且在一定浓度阈值之上使得药物组合物组分量比产生协同药效。具体而言,在药物组合物中,所述酸化剂或碱化剂的浓度应小于其有效消融浓度(例如可使得荷瘤小鼠实验中的抑瘤浓度≥40%)、但大于协同药效浓度阈值(例如:强碱或强酸的浓度≥0.5%、弱碱或弱酸的浓度≥2.5%)。而所述pH中和剂的浓度为这样一个浓度其使得所述药物组合物趋于中性化并且使其与所述酸化剂或碱化剂同浓度单药的pH之差的绝对值≥0.25。
此外,显示出协同药效的组合物经测定也是缓冲容量为>0.01mol·L -1·pH -1的缓冲溶液。
此外,本发明的组合物还可以通过添加局部协同物进一步提高药效、甚至是协同药效。
以下实施例在上述必要条件基础上对本发明的组合物的技术方案进行进一步研究。

在上表中,在腹腔注射系列中,组合物研究组11和15的抑瘤率均低于常规的有效抑瘤标准(40%),且研究组11与阴性对照组(02组)的瘤重差异无统计学意义(p>0.05)。出人意料的是,使用相同的组合物,研究组10的抑瘤率比研究组11高出2倍以上(86%∶36%),研究组14的抑瘤率比研究组14高出25倍以上(83%∶3%)。于是,通过完全不同的药物效应,相同组合物不同用药方式显示出明显不同的靶向和药理。经不同方式给药(腹腔注射和局部给药)后,同一给药组成的组合物的靶区(局部病变)组成可能完全不同。腹腔注射的组合物进入血液再到达局部病变处,其给药组成以完全被血液稀释甚至消解(例如不同组成在某些器官的不同滞留)。而局部给药的组合物的靶区组成则与其给药组成相同(至少在一段时间内)。換言之,经不同方式给药的组合物应当有不同的组成特征以获得协同药效。
这个不大合乎通常看法的现象(全身用药与局部用药显示出大不相同的效应)的出现,显然必须一个不大通常的技术方案。在上表中,在局部给药系列中,尽管各组合物的组分量比相同,组合物研究组12的抑瘤率仅为组合物研究组10的38%(33%∶86%)。组合物研究组16的抑瘤率仅为组合物研究组14的27%(22%∶83%)。实际上,组合物研究组12与组合物研究组16均未显示出协同作用。然而,在研究组10、1、5之间,组合物组10的q>1.00,显示出明显协同药效。在研究组14、3、8之间,组合物组14的q>1.00,显示出明显协同药效。这些结果进一步说明,要获得协同药效,不同方式给药的组合物可能必需完全不同的组成要素。全身给药的组合物通常要求组分量比即可(它们反正是要进入血液稀释的),而局部给药的组合物仅给出组分量比显然不行,还必须给出其它特征(例如浓度)。
此外,在研究组18、1、17之间,组合物组18的q>1.00,显示出明显协同药效。在研究组20、3、19之间,组合物组14的q>1.00,显示出明显协同药效。
总之,本发明的组合物在局部给药时似乎显示出与全身给药明显不同的药理。例如,其主要药理并非以分子形态分布至血液中去攻击病变组织内的病原体(例如瘤体内的肿瘤细胞)、而是在给药处以药液形态分布至组织间隙去攻击病变组织(例如瘤内组织)。
根据上述研究及更多的类似研究,可以得出酸碱中和组合及其局部协同物的组合物作 为局部活性成分在制备用于治疗局部病变疾病的局部药物中的应用技术方案的必要条件:
本发明的药物组合物的组成必须使得其可以局部给药、且在一定浓度阈值之上使得药物组合物组分量比产生协同药效。具体而言,在药物组合物中,所述酸化剂或碱化剂的浓度应≤其有效消融浓度(例如可使得荷瘤小鼠实验中的抑瘤浓度≥40%)但≥协同药效浓度阈值(例如:强碱或强酸酸化剂或碱化剂的浓度≥0.5%、弱碱或弱酸酸化剂或碱化剂的浓度≥2.5%)。在所述酸化剂或碱化剂浓度的基础上,各所述必要组分的量比条件为:所述酸化剂或碱化剂浓度如上所述;所述pH中和剂的浓度为其可与所述酸化剂或碱化剂产生协同作用的浓度(具体为可使得所述药物组合物趋于中性且令之与所述酸化剂或碱化剂同浓度单药的pH之差的绝对值≥0.25所需的浓度);所述局部协同物的浓度为其可与所述酸化剂或碱化剂以及它们各自的pH中和剂产生协同作用的浓度(例如为所述局部协同物在该组合物中的饱和溶解度的5%以上或25%以上)。
此外,显示出协同药效的组合物经测定也是缓冲容量为>0.01mol·L -1·pH -1的缓冲溶液。
此外,所述酸化剂与其pH中和剂、或所述碱化剂与其pH中和剂的协同组合看来是本发明的酸碱中和组合/局部协同物药物组合物的协同作用的基础。

试验动物分作A、B两个系列。A系列动物为不建模裸小鼠,随机分为4组,通过右腿外侧肌肉块内注射按照表11的组别1-4的药物,各组给药1次,注射量100μl/只;用药后在第3日对动物进行安乐死,解剖取出裸小鼠右腿外侧肌肉块标本,并进行大体病理分析,切片测量区别于正常肌肉的组织破坏(不完全坏死)区域面积(T3d)以及其中的组织严重(完 全坏死)破坏区域面积(S 3d),结果见下表11。

根据不同时间(3日、14日)的药效(r’ 3d、r’ 21d)分别计算短期药效的实际/预期比q 3d和中期药效的实际/预期比q 14d
在上表系列A中,组别2、4的S 3d分别为18.3±7.52mm 2、0mm 2,说明碱化剂符合预期 地具有最大化的局部作用强度,而中和组合中的pH中和剂符合预期地降低了碱化剂的局部作用强度。通常认为,坏死区面积应当与完全坏死区面积正相关。然而,组别2、4的T 3d却正好相反,分别为29.6±8.31mm 2、47.6±15.32mm 2,说明酸碱中和组合虽然产生组织严重性破坏的拮抗作用,却能产生组织一般性破坏的协同作用。
通常认为,肿瘤细胞增殖快速且强烈,抑瘤药效应与局部作用药物的完全坏死程度(局部作用最大化)才能有有效抑制短期抑瘤药效(r’ 3d)应与药物的强度(以组织严重破坏为标准)正相关。然而,系列B组别2、4的r’ 3d结果(r’ 4>r’ 2)却与系列A组别2、4的S 3d结果(S 2>S 4)相反,而与T 3d结果(T 2<T 4)一致,且组别4的短期实际/预期比q 3d>1.00,说明酸碱中和组合产生的组织一般性破坏的协同作用能够显示为瘤体组织破坏协同作用。通常认为,中期药效(r’ 14d)是短期药效(r’ 3d)的延续,当然一致。然而,系列B中组别2、4的中期比较结果(r’ 14d4/r’ 14d2=1.15)却与它们的短期比较结果(r’ 3d4/r’ 3d2=9.68)相去甚远。此外,组别4也显示中期协同作用、且中期和短期实际/预期比q 14d/q 3d为大于200%,说明酸碱中和组合产生了远超局部协同作用预期的新药理。
在上表系列B中,组别9、10中的酸碱中和组合/共用物显示了短期协同作用(q 3d>1.00)和中期协同作用(q 14d>1.00),而组别11、12中的酸碱中和组合/共用物却显示了短期拮抗作用(q 3d<1.00)和中期协同作用(q 14d>1.00),说明中期协同作用才是酸碱中和组合/共用物的基本特征。以上结果说明,本发明的酸碱中和组合或酸碱中和组合/共用物组合物的活性特征并非是提供最大化局部作用、而是提供适当局部作用在组织内的最大化渗透作用。
根据以上实施例的结果以及其它类似试验的结果,本发明的酸碱中和组合物(本发明组合物)在以下方面超过现有技术中的酸碱作用药物(例如高浓度酸、高浓度碱等等)(简称现有技术药物)的预期:
1)、其药理超预期:现有技术药物的特征药理为针对组织的有效局部作用、优选最大化局部作用,而本发明组合物的特征药理为组织间的有效渗透作用、优选最大化渗透作用;
2)、其药理组成超预期:为实现其不同药理,现有技术药物要求局部作用强度最大化,于是要求很高的酸(或碱)药理浓度(例如50%乙酸、14%氧氧化钠)及其纯酸(或碱)pH,而本发明组合物并不要求局部作用强度最大化,而要求渗透作用强度最大化,因而需要的是与酸(或碱)相反的酸碱中和组合,其包含适当量比(主要是保证足够中和作用)的酸化剂及其pH调节剂(或碱化剂及其pH调节剂),以及较小的酸化剂(或碱化剂)药理浓度(例如≤15%乙酸、≤5%氧氧化钠),结果为pH离酸(或碱)足够远的酸碱中和溶液;
3)、其技术效果超预期:在安全性上,现有技术药物的药理组成带来强烈的局部刺激性和酸(或碱)过量风险,而本发明组合物的药理组成却可以大大降低局部刺激性和酸(或碱)过量风险。在有效性上,本发明组合物药理组成的渗透作用能产生更大的有效作用范围。该疗效和该安全性使得本发明组合物比之现有技术药物更适合对局部刺激性和酸(或碱)过量风险的中老年、犹其是老年患者。
根据以上实施例的结果以及其它类似试验的结果,本发明包含酸碱中和组合及其共用物的组合物(本发明组合物)在以下方面超过现有技术可预期的包含局部作用药物(例如乙 醇、高浓度酸、高浓度碱等等)及其共用物的的组合物(简称现有技术组合物)的预期:
1)、其药理超预期:现有技术组合物的特征药理至多为局部作用协同,而本发明组合物的特征药理为包含酸碱中和组合的组织间有效渗透作用在内的协同作用;
2)、其药理组成超预期:上述酸碱中和组合的渗透作用药理组成超预期;
3)、其技术效果超预期:包含酸碱中和组合的组织间有效渗透作用在内的协同作用能产生超过现有技术组合物预期的中期疗效。
利用实施例1方法制备的一些其它本发明的组合物(例如各实施例中的协同组合物),在上述各肿瘤治疗中的应用也可以获得类似结果。
具有局部病变症状的疾病、尤其是顽固性疾病的局部给药的介入治疗通常以肿瘤为模型。在局部病变相关疾病中,肿瘤的机理极为复杂、最难治疗。以肿瘤为模型所获的局部给药技术方案通常也适用于其它局部病变相关疾病。以下实验研究了本发明组合物的更多应用。
除本文中描述的那些外,根据前述描述,本发明的多种修改对本领域技术人员而言会是显而易见的。这样的修改也意图落入所附权利要求书的范围内。本申请中所引用的各参考文献(包括所有专利、专利申请、期刊文章、书籍及任何其它公开)均以其整体援引加入本文。
