Objective

To evaluate the bioequivalence and safety of colchicine tablets under fasting and fed conditions in Chinese healthy participants.

Methods

A single-center, randomized, open, single-dose, two-formulation, two-period, two-sequence crossover design was adopted, enrolling 72 healthy participants, with 36 healthy participants in each group for fasting and fed conditions. Single oral dose 0.5 mg of test formulation (T) or the reference formulation (R) was taken across two periods,respectively. Plasma concentration of colchicine was determined using ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The pharmacokinetic parameters were calculated and the bioequivalence was evaluated using the non-compartmental model in Phoenix WinNonlin 8.2 software.

Results

The main pharmacokinetic parameters of a single oral colchicine tablet under fasting condition for T and R were as follows: Cmax were (2.70±0.88) and (2.54±0.87) ng·mL-1tmax were 0.98 (0.48, 2.00) and 0.98 (0.73, 2.48) h,t1/2 were (29.54±5.46) and (29.67±4.86) h,AUC0-t were (18.40±5.30) and (18.00±5.10) h·ng·mL-1,AUC0-∞ were (21.80±5.90) and (20.70±4.90) h·ng·mL-1, respectively. The main pharmacokinetic parameters under fed condition for T and R were as follows: Cmax were (2.49±0.84) and (2.58±1.00) ng·mL-1tmax were 1.48 (0.73, 3.98) and 1.48 (0.73, 4.00) h,t1/2 were (31.79±4.69) and (30.65±4.91) h,AUC0-t were (19.80±4.30) and (19.90±5.00) h·ng·mL-1,AUC0-∞ were (23.20±5.00) and (23.10±5.20) h·ng·mL-1, respectively. The geometric mean ratios of Cmax, AUC0-t and AUC0-∞ of the T and R formulations under fasting and fed conditions with a 90% confidence interval ranged from 80.00% to 125.00%.

Conclusion

Under both fasting and fed conditions, the colchicine tablet test formulation and reference formulation were bioequivalent in Chinese healthy subjects, and both were shown to be safe.

目的

评价秋水仙碱片在中国健康受试者体内空腹、餐后状态下的生物等效性和安全性。

方法

采用单中心、随机、开放、单剂量、两制剂、两周期、两序列交叉设计,入组 72 例健康受试者,空腹和餐后给药组各36例。受试者两周期分别服用受试制剂(T)或参比制剂(R)1片(每片0.5 mg),采用超高效液相色谱-串联质谱(UPLC-MS/MS)法测定血浆中秋水仙碱的浓度。用Phoenix WinNonlin 8.2 软件计算非房室模型药动学参数并进行生物等效性评价。

结果

空腹单次给药后秋水仙碱受试制剂和参比制剂的主要药代动力学参数Cmax分别为(2.70±0.88)和(2.54±0.87)ng·mL-1tmax分别为0.98(0.48,2.00)和0.98(0.73,2.48)h,t1/2分别为(29.54±5.46)和(29.67±4.86)h,AUC0-t分别为(18.40±5.30)和(18.00±5.10)h·ng·mL-1,AUC0-∞分别为(21.80±5.90)和(20.70±4.90)h·ng·mL-1;餐后单次给药后秋水仙碱受试制剂和参比制剂的主要药代动力学参数Cmax分别为(2.49±0.84)和(2.58±1.00)ng·mL-1tmax分别为1.48(0.73,3.98)和1.48(0.73,4.00)h,t1/2分别为(31.79±4.69)和(30.65±4.91)h,AUC0-t分别为(19.80±4.30)和(19.90±5.00)h·ng·mL-1,AUC0-∞分别为(23.20±5.00)和(23.10±5.20)h·ng·mL-1。空腹和餐后单次服用秋水仙碱受试制剂和参比制剂的Cmax、AUC0-t和AUC0-∞几何均值比的90%置信区间均落在80.00%~125.00%之间。

结论

在空腹和餐后状态下,秋水仙碱片受试制剂与参比制剂在中国健康受试者体内均具有生物等效性,且安全性良好。

目的

评价秋水仙碱片在中国健康受试者体内空腹、餐后状态下的生物等效性和安全性。

方法

采用单中心、随机、开放、单剂量、两制剂、两周期、两序列交叉设计,入组 72 例健康受试者,空腹和餐后给药组各36例。受试者两周期分别服用受试制剂(T)或参比制剂(R)1片(每片0.5 mg),采用超高效液相色谱-串联质谱(UPLC-MS/MS)法测定血浆中秋水仙碱的浓度。用Phoenix WinNonlin 8.2 软件计算非房室模型药动学参数并进行生物等效性评价。

结果

空腹单次给药后秋水仙碱受试制剂和参比制剂的主要药代动力学参数Cmax分别为(2.70±0.88)和(2.54±0.87)ng·mL-1tmax分别为0.98(0.48,2.00)和0.98(0.73,2.48)h,t1/2分别为(29.54±5.46)和(29.67±4.86)h,AUC0-t分别为(18.40±5.30)和(18.00±5.10)h·ng·mL-1,AUC0-∞分别为(21.80±5.90)和(20.70±4.90)h·ng·mL-1;餐后单次给药后秋水仙碱受试制剂和参比制剂的主要药代动力学参数Cmax分别为(2.49±0.84)和(2.58±1.00)ng·mL-1tmax分别为1.48(0.73,3.98)和1.48(0.73,4.00)h,t1/2分别为(31.79±4.69)和(30.65±4.91)h,AUC0-t分别为(19.80±4.30)和(19.90±5.00)h·ng·mL-1,AUC0-∞分别为(23.20±5.00)和(23.10±5.20)h·ng·mL-1。空腹和餐后单次服用秋水仙碱受试制剂和参比制剂的Cmax、AUC0-t和AUC0-∞几何均值比的90%置信区间均落在80.00%~125.00%之间。

结论

在空腹和餐后状态下,秋水仙碱片受试制剂与参比制剂在中国健康受试者体内均具有生物等效性,且安全性良好。

Objective

To evaluate the bioequivalence and safety of colchicine tablets under fasting and fed conditions in Chinese healthy participants.

Methods

A single-center, randomized, open, single-dose, two-formulation, two-period, two-sequence crossover design was adopted, enrolling 72 healthy participants, with 36 healthy participants in each group for fasting and fed conditions. Single oral dose 0.5 mg of test formulation (T) or the reference formulation (R) was taken across two periods,respectively. Plasma concentration of colchicine was determined using ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The pharmacokinetic parameters were calculated and the bioequivalence was evaluated using the non-compartmental model in Phoenix WinNonlin 8.2 software.

Results

The main pharmacokinetic parameters of a single oral colchicine tablet under fasting condition for T and R were as follows: Cmax were (2.70±0.88) and (2.54±0.87) ng·mL-1tmax were 0.98 (0.48, 2.00) and 0.98 (0.73, 2.48) h,t1/2 were (29.54±5.46) and (29.67±4.86) h,AUC0-t were (18.40±5.30) and (18.00±5.10) h·ng·mL-1,AUC0-∞ were (21.80±5.90) and (20.70±4.90) h·ng·mL-1, respectively. The main pharmacokinetic parameters under fed condition for T and R were as follows: Cmax were (2.49±0.84) and (2.58±1.00) ng·mL-1tmax were 1.48 (0.73, 3.98) and 1.48 (0.73, 4.00) h,t1/2 were (31.79±4.69) and (30.65±4.91) h,AUC0-t were (19.80±4.30) and (19.90±5.00) h·ng·mL-1,AUC0-∞ were (23.20±5.00) and (23.10±5.20) h·ng·mL-1, respectively. The geometric mean ratios of Cmax, AUC0-t and AUC0-∞ of the T and R formulations under fasting and fed conditions with a 90% confidence interval ranged from 80.00% to 125.00%.

Conclusion

秋水仙碱是从百合科植物秋水仙中提取得到的一种生物碱,既往主要用于治疗痛风和家族性地中海热[1-2],主要通过抑制微管聚合,阻断炎症体的激活而发挥抗炎镇痛作用[3]。由于其较多的毒副作用和抗痛风新药的出现,近年来秋水仙碱在痛风领域的应用明显减少,但其在新冠病毒感染、皮肤病和心脏纤维化等疾病的治疗效果引起越来越多的关注,尤其是2023年美国食品药品监督管理局(Food and Drug Administration, FDA)批准了秋水仙碱作为保护性心血管病的治疗药物后,这一古老药品正在重新焕发生机[4-6]。本文是一项关于空腹和餐后状态下单次口服两种秋水仙碱片在中国健康受试人群体内的生物等效性研究,将为该药的合理使用提供准确完整的药动学数据。

本试验采用单中心、随机、开放、单剂量、两制剂、两周期、两序列交叉研究设计。在空腹或餐后状态下给予秋水仙碱片T或R制剂,试验每周期给药1次,清洗期为7 d。受试者每周期给药前禁食至少10 h(餐后试验为进食高脂高热量餐前),于给药当天早晨按照随机表单次空腹或餐后口服T药 1片(0.5 mg)或R药1片(0.5 mg),240 mL常温水送服。给药前后1 h内禁止饮水。
空腹和餐后试验分别于0 h(服药前)及服药后0.25、0.50、0.75、1.00、1.25、1.50、1.75、2.00、2.50、3.00、3.50、4.00、6.00、8.00、12.00、24.00、36.00、48.00、72.00 h,通过静脉留置针采集上肢静脉血3 mL,置于K2EDTA抗凝管内,轻柔颠倒混匀,2~8 ℃,2 590 r·min-1离心10 min,分离血浆样本,分装成两份,其中检测管保证0.7 mL以上,在-80 ℃冻存备用。
色谱条件 采用ACQUITY UPLC C18色谱柱(1.7 μm,2.1 mm×50 mm)分离;流动相 A 为10.00 mmol·L-1乙酸铵水溶液(含0.10%甲酸),流动相B为乙腈; 梯度洗脱模式: 0~0.40 min, A 70%; 0.40~1.20 min, A 70%→30%; 1.20~1.30 min, A 30%; 流速:0.35 mL·min-1;柱温:40 ℃;进样量:10 μL。
质谱条件 电喷雾离子源:正离子模式,毛细管电压 1.0 kV,离子源温度 150 ℃,脱溶剂气温度 600 ℃,脱溶剂气流量1 000 L·h-1;多反应监测(multiplereactionmonitoring,MRM)模式:秋水仙碱监测离子对m/z 400.23→358.03,锥孔电压16V,碰撞能20ev,驻留时间163 ms;内标秋水仙碱-d6监测离子对m/z 406.38→361.94,锥孔电压50V,碰撞能18ev,驻留时间163 ms。
血浆样本处理 采用蛋白沉淀法处理血浆样本。取血浆 100 μL 至 96 孔聚丙烯板,加入秋水仙碱-d6内标工作液50 μL(空白样本加入80%甲醇水溶液),加入乙腈250 μL,振荡 2 min,室温条件下离心(4 000 r·min-1,15 min),取上清100 μL至另一个 96 孔聚丙烯板,加入0.1%甲酸水溶液200 μL,混匀,室温条件下离心(4 000 r·min-1,5 min),取上清液进样。
专属性 选取制备6 个不同来源人空白血浆、1个来源人溶血空白血浆、1 个来源人高脂空白血浆考察对内源性物质干扰、内标和待测物之间的干扰测定,秋水仙碱及其内标的保留时间分别为0.91和0.90 min。结果都没有受到干扰,具有很好的选择性,具体色谱图见图1
标准曲线与定量下限 配制含秋水仙碱的质量浓度为0.05、0.10、0.20、0.50、1.00、2.50、4.80、6.00 ng·mL-1的标准曲线样本进行分析,以秋水仙碱和秋水仙碱-d6的峰面积比值对其浓度进行加权回归(权重因子为 1/x2),绘制标准曲线。线性范围 0.05~6.00 ng·mL-1,定量下限为:0.05 ng·mL-1,标准曲线方程为:y=7.23×10-1x-4.00×10-3R2=0.999)。
精密度与回收率 取5个质量浓度(0.05、12.50×10-2、0.80、2.00、4.50 ng·mL-1)的 6 个重复质控样品评估批内准确度和精密度;每个质量浓度6个样本,连续测3批,评估批间准确度和精密度。取3个质量浓度(12.50×10-2、2.00、4.50 ng·mL-1)的6个重复质控样品比较经提取和未提取的待测物秋水仙碱及其内标的峰面积比值,考察回收率,结果见表1
基质效应和残留 在低、高质量浓度(12.50×10-2、4.50 ng·mL-1)水平下,秋水仙碱内标归一化的基质因子分别为95.62%、95.78%,变异系数(CV)分别为 3.96%、3.70%,均小于 15%,表明人血浆中的基质对秋水仙碱及其内标的测定无影响。在测定定量上限样本之后进样空白样本,结果显示残留不影响血浆中秋水仙碱的准确定量。
稳定性 秋水仙碱血浆样本在室温条件下保存24 h,-20 ℃条件下保存22 d,-70 ℃反复冻融5次,稳定性良好。
用Phoenix WinNonlin 8.2软件计算秋水仙碱的药动学参数(pharmacokinetics,PK), Cmax取实测值,AUC0-t、AUC0-∞采用非房室模型(non-compartmental model,NCA)计算;用SAS 9.4软件进行生物等效性分析。按照《以药动学参数为终点评价指标的化学药物仿制药人体生物等效性研究技术指导原则》和《生物等效性研究的统计学指导原则》要求,当秋水仙碱T和R制剂PK参数几何均值比的90%置信区间均完全落在80.00%~125.00%范围内,则说明两制剂间具有生物等效性。
空腹/餐后试验均入组36例健康受试者,受试者单次口服0.5 mg秋水仙碱片T或R的平均血药浓度-时间曲线,见图2
健康受试者空腹和餐后单次口服秋水仙碱片0.5 mg的药代动力学参数,见表2
空腹和高脂餐后服药条件下,受试者单次口服秋水仙碱片T和R制剂后的主要PK参数Cmax,AUC0-t和AUC0-∞几何均值比的90%置信区间分别为95.37%~117.18%、94.68%~109.87%、96.71%~114.30%和88.34%~106.37%、96.20%~103.38%、97.28%~105.76%,表明空腹和餐后状态下,秋水仙碱片两制剂在吸收速度和吸收程度上均生物等效。
空腹服用T药后,36例受试者中6例受试者共发生9例次不良反应,不良反应发生率为16.67%(6例/36例),服用R药后,36例受试者中4例受试者共发生4例次不良反应,不良反应发生率为11.11%(4例/36例)。餐后服用T药后,36例受试者中6例受试者共发生10例次不良反应,不良反应发生率为16.67%(6例/36例),服用R药后,36例受试者中7例受试者共发生8例次不良反应,不良反应发生率为19.44%(7例/36例)。主要不良反应包括高尿酸血症、丙氨酸氨基转移酶升高、天门冬氨酸氨基转移酶升高、胆红素升高、尿潜血等,均为1-2级。受试制剂和参比制剂均未观察到严重不良反应和导致受试者脱落的不良反应。两制剂的不良反应发生率没有显著差异。
秋水仙碱作为一种老药,其作用机制、药理特点已经研究明确。可能是由于临床用量的减少,一直未见秋水仙碱片在中国健康受试者体内的一致性评价报道。本研究以药动学参数为评价指标,比较了北京嘉林药业股份有限公司生产的秋水仙碱片与TAKATA SEIYAKUCO.,Ltd生产的秋水仙碱片在中国健康受试者体内的生物等效性,结果显示两制剂在空腹和餐后状态下均能达到生物等效,且空腹和餐后状态下的药动学参数没有明显变化。秋水仙碱片整体表现出快速吸收、缓慢消除的药动学特点。在安全性评价方面,本研究发现健康受试者单次口服秋水仙碱后普遍出现一过性的血尿酸值升高,部分受试者的血尿酸值超过正常范围。该不良反应未见报道,其作用机制和长期应用效果也不明确,可通过开展针对性的研究,积累长期用药的临床数据,进行深入探讨,以保障秋水仙碱的长期用药安全性。
秋水仙碱服药量小,在人体内血药浓度较低,文献报道中多采用固相萃取法及液液萃取法进行血样前处理,过程较复杂,且耗材成本较高,分析时间较长[7-8]。本文建立了超高相液相色谱-串联质谱法定量测定人血浆样本中秋水仙碱浓度的方法,采用蛋白沉淀法进行样本的前处理,最低定量浓度达到0.05 ng·mL-1,每个样本分析用时仅2 min,具有样本处理简便、分析时间短、专属性强,灵敏度高,检测通量大等优点,适合于秋水仙碱片的药代动力学研究。
