曲美替尼(TRA)是一种丝裂原活化细胞外信号调节激酶1/2可逆性抑制剂 [
随着TRA的广泛应用,其不良反应报道日益增多 [
1) 目标药品不良事件源数据收集选取FAERS数据库2017年第1季度至2022年第4季度共24个季度的不良事件数据,以“TRAMETINIB”匹曲美替尼,从中筛选出以曲美替尼为首要怀疑药物的报告。
2) 药品不良事件编码系统FAERS 数据库中ADE均采用(Medical Dictionary for Regularly Activities, MedDRA)中首选语(preferred terms, PT)、高位组语(high level group term, HLGT)、系统器官分类(system organ class, SOC)进行编码并语言汉化 [
本研究选用ROR和MHRA法进行不良事件数据挖掘,这两种方法基于比例失衡法四格表(表1),利用相应的公式计算ROR值和比例报告比值比(proportional reporting ratio, PRR)值 [
药品 | 目标不良反应报告数 | 其他不良反应报告数 | 合计 |
---|---|---|---|
目标药物 | a | b | a + b |
其他药物 | c | d | c + d |
合计 | a + c | b+d | N = a + b + c + d |
表1. 比例失衡法四格表
方法 | 公式 | 阈值 |
---|---|---|
ROR | ROR = ( a / c ) ( b / d ) = ad bc SE ( ln ROR ) = ( 1 a + 1 b + 1 c + 1 d ) 95 % C l = e ln ( ROR ) ± 1.96 ( 1 a + 1 b + 1 c + 1 d ) | a ³ 3; ROR的95%Cl下限 > 1,则提示生成一个信号 |
MHRA | PRR = a / ( a + b ) c / ( c + d ) χ 2 = ( ad − bc ) 2 ( a + b + c + d ) ( a + b ) ( c + d ) ( b + d ) ( a + c ) | a ³ 3; PRR ≥ 2、看到、卡方(c2) ≥ 4,则提示生成一个信号 |
表2. ROR法与MHRA法公式及阈值
使用MedDRA 25.1版本对筛选的数据进行标准化,合并中文含义相同的PT,记录PT的总报告数;通过相应的公式计算ROR值、PRR值和95% CI下限。ROR法中报告数a ≥ 3、且95% CI下限 > 1,则生成1个有效信号;MHRA法中报告数a ≥ 3、且PRR ≥ 2,c2≥ 4,则提示1个有效信号,从而筛选出有信号的PT。
2017年第1季度至2022年第4季度的ADE背景信号共8,787,823条,其中以TRA为首要怀疑药物的ADE报告4393份,其中良性、恶性及性质不明的肿瘤的ADE报告数最多,构成比为17.03%,其次是全身性疾病及给药部位各种反应,构成比为14.27%,神经系统ADE报告为86份,构成比为3.77% (见图1)。
运用ROR和MHRA法双重判定是否为有信号PT,共发现15个TRA相关呼吸系统有信号PT,其中15个是新发现的说明书中未详细记载的信号,包括失语,共济失调,中枢神经系统疾病,癫痫,面部瘫痪等。根据MedDRA 25.1对有信号的PT进行HGLT分类排序,共划分成7个HGLT,分类后HGLT的信号数、ADE信号数见表1。在86份有信号PT的ADE报告中,神经类疾病的构成比最高(见表3),为41.86%,包括失语,共济失调,中枢神经病损,困倦等。其次是癫痫发作(26.74%),包括惊厥发作和癫痫。
图1. TRA累及器官系统不良事件发生例数构成比
HLGT | 排名前5位的信号 | 信号数 | 报告数构成比 |
---|---|---|---|
神经类疾病 | 失语(5)、共济失调(5)、中枢神经系统病损(3)、困倦(7)、神经系统病变(3)、神经代偿失调(3)、晕厥(10) | 7 | 41.86% |
癫痫发作 | 癫痫(6)、惊厥发作(17) | 2 | 26.74% |
外周神经类疾病 | 外周运动神经元病(5)、外周感觉神经元病(6) | 2 | 12.79% |
颅内压升高及脑积水 | 脑积水(5) | 1 | 5.81% |
颅神经疾病 | 面部瘫痪(4) | 1 | 4.65% |
中枢神经系统血管神经疾病 | 颅内出血(4) | 1 | 4.65% |
运动障碍 | 轻偏瘫(3) | 1 | 3.94% |
15 | 100.00% |
表3. TRA相关神经系统ADE信号HLGT项下排序
本研究从FAERS中提取TRA的不良事件报告共4393份,共涉及包括良性、恶性及性质不明的肿瘤,各类检查、感染及侵染类疾病等11个SOC,与说明书及文献报道的ADR基本一致,证实了本研究的可靠性。通过图1可以看出良性、恶性及性质不明的肿瘤的构成比最高,这可能和原发疾病有关,但也需关注原发疾病以外的部位以及疾病进展情况。
目标事件即TRA相关神经系统不良事件报告86份(3.77%),其中主要包括神经类疾病、癫痫发作、外周神经类疾病、颅内压升高及脑积水、颅神经疾病、中枢神经系统血管神经疾病、运动障碍7个方面。此外,我们发现TRA相关神经系统疾病在说明说均未提及,有相关基础疾病的患者需加强监测。
值得注意的是,外周神经类疾病的在HLGT项下的构成比为12.79% (如表3所示),虽然构成比相对来说不是很高,但外周运动神经元病PRR与卡方(69.87, 329.25)值较强,说明TRA 与外周神经类疾病发生关联度较高,运动神经元病是一种病因未明的选择性侵犯脊髓前角细胞、脑干后组运动神经元、皮质椎体细胞及锥体束的慢性进行性变性疾病,临床表现为肌无力、肌萎缩和锥体束征不同的组合 [
本研究存在一定的局限性:第一,数据挖掘技术无法弥补自发报告系统固有的局限性,如少报、假报、不完全报、上报不准确等,这些均可能导致研究结论的偏倚。第二,我们的研究方法仅用于定性研究,不能根据不良事件的总数来量化TRA相关神经系统不良事件的信号。第三,药品上市时间等因素在一定程度上影响ADE上报的数量。
综上所述,本研究基于FAERS数据库分析了TRA可能增加神经系统不良事件的风险,其中外周神经元系统疾病和脑积水的相关性较强,且未在现有的说明书中提及,需加强用药前运动神经及脑部相关基础疾病的评估,以及用药中、用药后的监测,及时诊断和治疗,防止TRA相关神经系统不良事件的发生。
