It is a dual agonist of glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (Glucagon Receptor, GCGR). agent.

Description

使用mazdutide的治疗方法
相关申请的引用
本发明要求于2022年6月1日提交中国专利局、申请号为202210622648.7、发明名称为“使用mazdutide的治疗方法”的发明专利申请的优先权,通过引用将其全部内容结合在本发明中。
技术领域
本发明属于医药领域,具体涉及使用mazdutide的治疗方法。
背景技术
超重或肥胖者首选的基础治疗手段为生活方式干预,但其中仍有相当一部分患者由于种种原因无法减重或未达到期望的减重目标,对此类患者可考虑使用药物辅助减重。我国指南建议,BMI≥28kg/m2且经过3个月的生活方式干预仍不能减重5%,或BMI≥24kg/m2合并高血糖、高血压、血脂异常、非酒精性脂肪肝(Non-alcoholic fatty liver disease,NAFLD)、负重关节疼痛、睡眠呼吸暂停综合征等肥胖相关并发症之一的患者,在生活方式和行为干预基础上推荐应用药物减重治疗。
目前,经FDA批准的长期(≥12周)肥胖治疗药物主要包括:芬特明(phentermine)和托吡酯(topiramate)缓释胶囊、安非他酮(bupropion hydrochloride-naltrexone hydrochloride)、利拉鲁肽(liraglutide)和司美格鲁肽(semaglutide)注射液,以及短期应用的减重药物(<12周)包括安非拉酮(diethylpropion)、苯甲曲秦(phendimetrazine)、芬特明(phentermine)、苄非他明(benzphetamine)等。早期上市的减肥药虽有一定的降低体重效果,但是副反应同样令人关注,并限制了它们的使用。如安非拉酮可能引起心动过速和失眠等,芬特明可能引起失眠、口干和便秘,芬特明和芬氟拉明的复方制剂可能引起原发性肺动脉高压和心脏瓣膜关闭不全(但单独应用芬特明则未见明显相关性),奥利司他可能导致脂溶性维生素缺乏、胃肠胀气、便急、脂肪泻等。目前已上市多种GLP-1单受体激动剂,如利拉鲁肽等。以司美格鲁肽为例,其为目前全球已上市的疗效最好的减重药物,连续给药12周体重降幅约6%,连续给药1年体重降幅约13-16%。但对于BMI较高的肥胖者,例如BMI>30kg/m2的肥胖者,由于其减重需求更高,GLP-1单受体激动剂虽然展现出一定的减重疗效,但在肥胖治疗领域仍存在巨大的未满足医学需求。
近年来,靶向多个代谢通路的多重受体激动剂成为代谢性疾病领域药物开发的热点。多项临床前和临床研究结果表明,GLP-1受体激动剂与其他肠促胰激素共同给药显示出促进或协同效应。与单靶点激动剂单用或联用相比较,在多种受体上具备平衡活性的单分子多重受体激动剂有望在疗效最大化、副作用降低和药代动力学等方面获得进一步提升。因此,以GLP-1为基础的单分子多重受体激动剂具有协同增效、提高耐受性和改善安全性等获益。
Mazdutide是一种与哺乳动物胃泌酸调节素(oxyntomodulin,OXM)类似的长效合成肽。OXM是营养摄入后由人肠道L细胞分泌的肽类激素,是胰高血糖素样肽-1受体(GLP-1R)和胰高血糖素受体(Glucagon Receptor,GCGR)的双重激动剂。GLP-1R和GCGR双重激动剂将胰高血糖素的产热和脂解作用与GLP-1的延缓胃排空作用相结合以产生显著的减重作用,并通过GLP-1的促胰岛素分泌作用缓冲胰高血糖素的升血糖作用,从而有效控制血糖。在人体内注射OXM可显著降低体重和食欲,并增加能量消耗。作为OXM类似物,mazdutide通过同时激活GLP-1R和GCGR发挥作用。

发明的效果
在一些实施方案中,本发明提供的预防或治疗肥胖或超重的方法,通过以特定的给药方案施用mazdutide或其药学上可接受的盐,可实现明显的减重效果,并可同时改善受试者的血压、血脂和血清尿酸水平。
在一些具体的实施方案中,本发明以具有不同施用剂量的给药方案I或给药方案II向有需要的患者施用mazdutide或其药学上可接受的盐。本发明发现,对于mazdutide施用剂量不同的给药方案I和给药方案II,均能展现出显著的减重疗效,且患者在给药过程中的整体耐受性和安全性良好,具有高的临床施用的安全性。
在一些优选的实施方案中,本发明以给药方案II向有需要的患者施用mazdutide或其药学上可接受的盐。与给药方案I相比,给药方案II具有更优异的减重效果。与此同时,本发明意外发现,相比给药方案I而言,给药方案II中施用mazdutide的持续时间更短,给药剂量也更低,但其受试者体重降幅却更高。因此,本发明提供的给药方案II并非通过剂量和时间的增加带来更优减重疗效,而是通过特定给药方案以较低剂量和较短时间达到最优的减重疗效,具有重要的临床应用前景。
此外,与施用其他同类药物的给药方案相比,本发明中提供的给药方案II也具有更为突出的减重 效果。
同时,本发明通过在给药方案II中延长维持剂量的给药时间,进一步得到了更优的减重疗效,且在延长的给药过程中,患者整体耐受性和安全性依然良好,具有高的临床施用安全性。

3、给药方法及过程
本研究共5个队列,每个队列的受试者按2:1比例随机分成mazdutide治疗组(n=8)和安慰剂组(n=4)。队列1、队列2、队列3、队列4和队列5中mazdutide或安慰剂的皮下注射给药方案分别描述如下:
药物规格:安慰剂规格与制剂相匹配;
给药方式:皮下注射,每周一次;
给药方案:
队列1(记作3mg队列):1.0mg连续给药4周+2.0mg连续给药4周+3.0mg连续给药4周;
队列2(记作4.5mg队列):1.5mg连续给药4周+3.0mg连续给药4周+4.5mg连续给药4周;
队列3(记作6mg队列):2.0mg连续给药4周+4.0mg连续给药4周+6.0mg连续给药4周;
队列4(记作10mg队列):2.5mg连续给药4周+5.0mg连续给药4周+7.5mg连续给药4周+10.0mg连续给药4周;
队列5(记作9mg队列):3.0mg连续给药4周+6.0mg连续给药4周+9.0mg连续给药4周。
4、实验结果
本研究共5个队列,mazdutide不同剂量均展现出显著的减重疗效。给药12周,队列1(1mg-2mg-3mg)、队列2(1.5mg-3mg-4.5mg)、队列3(2mg-4mg-6mg)和队列5(3mg-6mg-9mg)中mazdutide组受试者的体重较基线百分比变化的最小二乘均值分别为-4.81%、-6.40%、-6.05%和-11.7%;给药16周,队列4(2.5mg-5mg-7.5mg-10mg)中mazdutide组受试者的体重较基线百分比变化的最小二乘均值为-9.5%,上述结果见附图1。队列4和队列5中受试者的BMI较基线的平均变化结果如图2所示。
由此可见,各剂量组在受试者中均展现出良好的减重疗效,且连续给药12周或16周后减重效果 仍未达到平台期,而且本发明队列5的给药方案在患者中的减重效果尤其突出。
此外,既往的研究显示GLP-1类药物的减重疗效呈剂量依赖性,但通过比较本发明队列4和队列5的给药方案,可以发现,相比队列4,队列5的给药方案中药量更低,疗程更短,证明本发明队列5并非通过剂量和时间的增加带来更优减重疗效,而是通过特定给药方案以较低剂量和较短时间达到最优的减重疗效,突破了现有技术中对于GLP-1类药物的给药方案认知,具有重要的临床应用前景。
同时,在减重疗效的基础上,本发明的5个队列中mazdutide不同剂量还展现出较好的改善血压、血脂和血清尿酸水平等指标的有益效果。其中本发明队列4和队列5中受试者的血压、血脂和血清尿酸水平较基线的平均变化统计结果如图3-5所示。
此外,通过比较其他同类药物以不同剂量给药方案施用12周后的患者体重降幅,如Semaglutide的2.4mg给药方案(皮下注射Semaglutide,每周一次,每次2.4mg;具体参见Khoo TK,Lin J.Once-Weekly Semaglutide in Adults with Overweight or Obesity.N Engl J Med.2021 Jul 1;385(1):e4.)和Tirzepatide的10mg或15mg给药方案(分别为:皮下注射Tirzpatide,以2.5mg的剂量开始,每周一次,剂量每4周增加2.5mg,直至达到10mg或15mg;具体参见Frías JP,Davies MJ,Rosenstock J,Pérez Manghi FC,Fernández LandóL,Bergman BK,Liu B,Cui X,Brown K;SURPASS-2 Investigators.Tirzepatide versus Semaglutide Once Weekly in Patients with Type 2 Diabetes.N Engl J Med.2021 Aug 5;385(6):503-515.),可以发现,本发明队列5的mazdutide给药方案依然在受试者中展现出了尤为突出的减重效果,上述结果见附图6。
安全性结果:5个队列在研究过程中都未出现研究药物剂量调整。多数治疗期不良事件(Treatment Emergent Adverse Events,TEAE)为轻度,未报告重度TEAE,无导致永久停药的TEAE发生,无治疗期严重不良事件(Treatment Emergent Serious Adverse Events,TESAE)发生,无重度低血糖事件发生。证明患者在给药过程中的整体耐受性和安全性良好,本发明提供的给药方案具有高的临床施用的安全性。

3、给药方法及过程
本研究计划入组约80例受试者,筛选合格的受试者将接受安慰剂导入2周,导入成功后按照mazdutide:安慰剂=3:1的比例随机入组,在给药方案下进行给药。在受试者给药完成后,可进行12周停药随访。
药物规格:安慰剂规格与制剂相匹配;
给药方式:皮下注射,每周一次;
给药方案:3.0mg连续给药4周+6.0mg连续给药4周+9.0mg连续给药16周或40周。
4、实验结果
本研究阶段入组80例受试者,筛选合格的受试者接受安慰剂导入2周,导入成功后随机分组至mazdutide组或安慰剂组。给药方式如下:3.0mg QW给药4周+6.0mg QW给药4周+9.0mg QW给药16周。在达到24周主要终点后,受试者可选择进行24周的延长治疗。
目前研究已达到主要终点,结果显示,连续给药24周后,mazdutide组和安慰剂组体重较基线的百分比变化分别为-13.25%和2.11%。与安慰剂组相比,mazdutide组连续给药24周后体重相对基线百分比变化的差值为-15.36%(p值小于0.0001)。mazdutide组和安慰剂组体重较基线的变化值分别为-12.55kg和2.12kg。与安慰剂组相比,mazdutide组连续给药24周后体重相对基线变化的差值为-14.67kg(p值小于0.0001)。连续给药24周后,mazdutide组分别有81.7%、65.0%、31.7%和21.7%的受试者体重较基线下降至少5%、10%、15%和20%,而安慰剂组无受试者体重降幅达到5%及以上。
由此可见,相比实施例1中队列5给药方案(连续给药12周),通过增加维持剂量的给药时间(例如9.0mg维持剂量连续给药16周或40周等),可以进一步提高在肥胖受试者中的减重疗效。
安全性方面,截至目前,mazdutide治疗组整体耐受性和安全性良好,治疗组脱落率整体低于安慰剂组,治疗组中无受试者因不良事件提前终止治疗,无严重不良事件发生。除COVID-19感染外,最常发生的治疗期不良事件为胃肠道相关不良事件,且大多数为轻度或中度并均为一过性。由此证明,本发明提供的给药方案具有高临床施用安全性。
