Objective:

To establish an HPLC-MS/MS method for the determination of FCN-437c in human plasma and its application to the phase I clinical study of FCN-437c.

Methods:

Following protein precipitation, plasma was injected and measured using HPLC-MS/MS method. The analytes were separated on a YMC Triart PFP column (50 mm×2.1 mm, 5 μm) using 0.5% formic acid (containing 5 mmol·L-1 of ammonium acetate, A) and acetonitrile (B) as the mobile phase with gradient elution at the flow rate of 0.5 mL·min-1, the column temperature was set at 35 ℃, the injection amount was 2 μL, and the injector temperature was 10 ℃. MS detection was performed with multiple reaction monitoring (MRM) mode using positive electrospray ionization. The ion transitions were m/z 549.4→449.4 for FCN-437c and m/z 552.3→449.3 for FCN-437-D3, respectively. Other mass spectrometry parameters were TEM, 500 ℃, GS1, 276 kPa, GS2, 207 kPa, DP, 100 V, CXP, 25 V.

Results:

The linear range of FCN-437c in human plasma was 5-1 000 ng·mL-1 (r=0.999 0). The lower limit of quantification was 5 ng·mL-1. The intra-batch and inter-batch precisions were less than 2.0% and 4.1%, respectively. The average recovery was 104.0% (FCN-437c), 78.6% (FCN-437-D3), and the internal standard normalized matrix factor was 100%-102%. The stock solution of FCN-437c was stable at 4 ℃ for 202 d, the working solution of FCN-437c and internal standard were stable at room temperature for 24 h. FCN-437c in human plasma was investigated to be stable at room temperature for 20 h, four cycles of freeze-thaw, -20 ℃ for 134 d, -80 ℃ for 662 d, as well as for 24 h in the autosampler after treatment. The whole blood samples were stable at room temperature for 4 h. This method was applied to the determination FCN-437c in human plasma, and the deviation between the test results and the initial values of 97.0% ISR samples was within ±20%. The accuracy was 102.0%-108.0% after 10-fold dilution of plasma samples. The cumulative ratio of RAUC0-24 and RC max was 1.33 times and 1.59 times when FCN-437c was administered continuously compared with single administration.

Conclusion:

This method is simple, accurate, robust and specific, which can meet the requirements of quantitative analysis of FCN-437c in human plasma and also can be used to determine FCN-473c in human plasma of the phase I clinical study.

目的:

建立测定人血浆中FCN-437c药物浓度的HPLC-MS/MS方法,并用于FCN-437c的Ⅰ期临床研究。

方法:

血浆经蛋白沉淀处理后,采用HPLC-MS/MS法进样测定。色谱柱为YMC Triart PFP柱(50 mm×2.1 mm,5 μm),以0.5%甲酸水溶液(含5 mmol·L-1乙酸铵,A)-乙腈(B)为流动相,梯度洗脱,流速为0.5 mL·min-1,柱温为35 ℃,进样量为2 μL,进样器温度为10 ℃。质谱采用ESI+,MRM模式。检测离子反应对为m/z 549.4→449.5(FCN-437c)和m/z 552.5→449.0(FCN-437-D3,氘代内标),雾化气压力276 kPa,辅助气压力207 kPa,去簇电压100 V,碰撞室出口电压25 V。

结果:

人血浆中FCN-437c的线性范围为5~1 000 ng·mL-1r=0.999 0),定量限为5 ng·mL-1,批内、批间精密度分别小于2.0%和4.1%,平均回收率为104.0%(FCN-437c)、78.6%(FCN-437-D3),内标归一化基质因子为100%~102%。FCN-437c储备液4 ℃放置202 d,FCN-437c及FCN-437-D3工作液室温放置24 h,血浆样品室温放置20 h、冻融四循环、-20 ℃放置134 d、-80 ℃放置662 d,样品处理后自动进样器放置24 h,全血样品室温放置4 h均稳定。应用此方法检测了受试者口服FCN-437c后血浆药物浓度,ISR样品测试结果为97.0%与初测值的偏差在±20%以内。血浆样本稀释10倍后准确度为102.0%~108.0%。FCN-437c连续给药与单次给药相比,RAUC0-24RCmax的累积比为1.33倍与1.59倍。

结论:

本方法简便、准确、耐用、专属性强,可满足人血浆中FCN-437c的定量分析的要求。

目的:

建立测定人血浆中FCN-437c药物浓度的HPLC-MS/MS方法,并用于FCN-437c的Ⅰ期临床研究。

方法:

血浆经蛋白沉淀处理后,采用HPLC-MS/MS法进样测定。色谱柱为YMC Triart PFP柱(50 mm×2.1 mm,5 μm),以0.5%甲酸水溶液(含5 mmol·L-1乙酸铵,A)-乙腈(B)为流动相,梯度洗脱,流速为0.5 mL·min-1,柱温为35 ℃,进样量为2 μL,进样器温度为10 ℃。质谱采用ESI+,MRM模式。检测离子反应对为m/z 549.4→449.5(FCN-437c)和m/z 552.5→449.0(FCN-437-D3,氘代内标),雾化气压力276 kPa,辅助气压力207 kPa,去簇电压100 V,碰撞室出口电压25 V。

结果:

人血浆中FCN-437c的线性范围为5~1 000 ng·mL-1r=0.999 0),定量限为5 ng·mL-1,批内、批间精密度分别小于2.0%和4.1%,平均回收率为104.0%(FCN-437c)、78.6%(FCN-437-D3),内标归一化基质因子为100%~102%。FCN-437c储备液4 ℃放置202 d,FCN-437c及FCN-437-D3工作液室温放置24 h,血浆样品室温放置20 h、冻融四循环、-20 ℃放置134 d、-80 ℃放置662 d,样品处理后自动进样器放置24 h,全血样品室温放置4 h均稳定。应用此方法检测了受试者口服FCN-437c后血浆药物浓度,ISR样品测试结果为97.0%与初测值的偏差在±20%以内。血浆样本稀释10倍后准确度为102.0%~108.0%。FCN-437c连续给药与单次给药相比,RAUC0-24RCmax的累积比为1.33倍与1.59倍。

结论:

本方法简便、准确、耐用、专属性强,可满足人血浆中FCN-437c的定量分析的要求。

Objective:

To establish an HPLC-MS/MS method for the determination of FCN-437c in human plasma and its application to the phase I clinical study of FCN-437c.

Methods:

Following protein precipitation, plasma was injected and measured using HPLC-MS/MS method. The analytes were separated on a YMC Triart PFP column (50 mm×2.1 mm, 5 μm) using 0.5% formic acid (containing 5 mmol·L-1 of ammonium acetate, A) and acetonitrile (B) as the mobile phase with gradient elution at the flow rate of 0.5 mL·min-1, the column temperature was set at 35 ℃, the injection amount was 2 μL, and the injector temperature was 10 ℃. MS detection was performed with multiple reaction monitoring (MRM) mode using positive electrospray ionization. The ion transitions were m/z 549.4→449.4 for FCN-437c and m/z 552.3→449.3 for FCN-437-D3, respectively. Other mass spectrometry parameters were TEM, 500 ℃, GS1, 276 kPa, GS2, 207 kPa, DP, 100 V, CXP, 25 V.

Results:

The linear range of FCN-437c in human plasma was 5-1 000 ng·mL-1 (r=0.999 0). The lower limit of quantification was 5 ng·mL-1. The intra-batch and inter-batch precisions were less than 2.0% and 4.1%, respectively. The average recovery was 104.0% (FCN-437c), 78.6% (FCN-437-D3), and the internal standard normalized matrix factor was 100%-102%. The stock solution of FCN-437c was stable at 4 ℃ for 202 d, the working solution of FCN-437c and internal standard were stable at room temperature for 24 h. FCN-437c in human plasma was investigated to be stable at room temperature for 20 h, four cycles of freeze-thaw, -20 ℃ for 134 d, -80 ℃ for 662 d, as well as for 24 h in the autosampler after treatment. The whole blood samples were stable at room temperature for 4 h. This method was applied to the determination FCN-437c in human plasma, and the deviation between the test results and the initial values of 97.0% ISR samples was within ±20%. The accuracy was 102.0%-108.0% after 10-fold dilution of plasma samples. The cumulative ratio of RAUC0-24 and RC max was 1.33 times and 1.59 times when FCN-437c was administered continuously compared with single administration.

Conclusion:

This method is simple, accurate, robust and specific, which can meet the requirements of quantitative analysis of FCN-437c in human plasma and also can be used to determine FCN-473c in human plasma of the phase I clinical study.

FCN-437c是一种具有我国自主知识产权的口服CDK4/6抑制剂类抗肿瘤新药,其作用机制在于通过选择性抑制 CDK4/6-Cyclin D二聚体激酶活性,阻碍Rb的磷酸化,阻断细胞从G1期进入S期,使细胞周期停滞于G1期,从而抑制肿瘤细胞的增殖,临床用于激素受体(HR)阳性,表皮生长因子受体2(HER2)阴性的晚期或转移性乳腺癌的女性患者的治疗。CDK4/6是细胞周期调控通路中的关键蛋白[1-2],靶向CDK4/6被认为是抗癌方法的1个范式转变[3],CDK4/6抑制剂在多项临床试验中被证实对HR+/HER2-乳腺癌患者具有良好的疗效[4]。目前,全球已经有3个CDK4/6抑制剂(palbociclib、ribociclib、abemaciclib)上市[5-8],3个抑制剂均包含ATP-竞争性抑制以及CDK4/6选择性的关键分子结构的2-氨基吡啶和哌嗪环[9]。FCN-437c与其药物结构类似,作为单药治疗具有抗肿瘤活性和良好的安全性[10-11]
迄今为止,已发表的检测CDK4/6抑制剂的LC-MS/MS检测方法主要使用C8柱、C18柱、苯基柱[12-16]。FCN-437c在初步方法开发中尝试用C8柱、C18柱、苯基柱等多种色谱柱,采用不同pH调节剂的超纯水为水相,乙腈或甲醇为有机相,发现在上述色谱柱上均不易保留,无法形成特征性色谱峰。为了增强FCN-437c的保留情况,更换为YMC Triart PFP色谱柱。经探索发现,FCN-437c的洗脱相为水相,为获得最佳的色谱保留效果,采用水相逐步增加的梯度洗脱方法。经过方法学优化,最终建立了一种简便、专属性强的HPLC-MS/MS测定人血浆中FCN-437c浓度的方法,用于FCN-437c的人体临床研究,评价FCN-437c在ER+、HER2-的晚期乳腺癌绝经后女性受试者中的药代动力学特征,为临床用药的有效性及安全性提供依据。

采用YMC Triart PFP色谱柱(50 mm×2.1 mm,5 μm);流动相A为0.5%甲酸水溶液(含5 mmol·L-1乙酸铵),流动相B为乙腈,梯度洗脱(见表1),流速 0.5 mL·min-1,柱温35 ℃,进样量2 μL,进样器温度10 ℃。
选用电喷雾离子源(ESI),正离子电离模式,采用多反应监测(MRM)的质谱扫描方式进行检测,在45 V的碰撞能量下,检测FCN-437c离子对通道m/z为549.4→449.5,FCN-437-D3离子对通道m/z 552.5→449.0。其他质谱参数:雾化气压力为276 kPa,辅助气压力为207 kPa,去簇电压为100 V,碰撞室出口电压为25 V,运行时间为6 min。
精密称取FCN-437c对照品约10 mg,置10 mL量瓶中,二甲基亚砜(DMSO)充分溶解后用甲醇定容,配制FCN-437c储备液(S1),同法配制FCN-437c储备液(S2),S1和S2分别用于配制标准曲线和质控样品。称取FCN-437-D3对照品10 mg,置10 mL量瓶中,用二甲基亚砜(DMSO)充分溶解后用甲醇定容,配制FCN-437-D3储备液。继续以甲醇进行稀释,配制成质量浓度为100 μg·mL-1的FCN-437-D3标准工作液。精密吸取FCN-437-D3标准工作液10 μL,加入乙腈-水(90∶10)100 mL,即得10 ng·mL-1 FCN-437-D3溶液。上述溶液均使用经校准的移液器和容量瓶进行配制,并保存于4 ℃冰箱待用。
采用蛋白沉淀法进行血浆样本前处理。取血浆样本50 μL,加入含FCN-437-D3(浓度为10 ng·mL-1)的乙腈-水(90∶10)200 μL,振摇5 min,离心(14 000 r·min-1,10 min,室温),取上清液50 μL加入0.5%甲酸水溶液(含5 mmol·L-1乙酸铵)50 μL,涡旋混匀后用于进样分析,进样量为2 μL。

分别将1 μg·mL-1 FCN-437c和FCN-437-D3溶液,以恒定流速泵入MS/MS系统,进行母离子及碎片离子分析,FCN-437c和FCN-437-D3的二级全扫描质谱图见图1
在本实验采用的检测条件下,FCN-437c和FCN-437-D3的保留时间均为2.97 min,峰形良好。与空白血浆样品色谱图比较,内源性物质不干扰FCN-437c及FCN-437-D3的测定,FCN-437-D3对FCN-437c检测通道亦无干扰。结果表明,该方法特异性良好。此外,在标准曲线的定量上限样品之后进样分析的双空白血浆样品中,FCN-437c峰面积均为0,且FCN-437-D3峰面积均为0,表明本方法无明显系统残留。结果见图2
用甲醇-水(50∶50)稀释FCN-437c储备液(S1),配制成质量浓度分别为100、200、800、2 000、8 000、10 000、16 000、20 000 ng·mL-1(C1~C8)的FCN-437c工作液。取上述8个浓度的工作液20 μL,置于1.5 mL塑料离心管中,分别加入空白人血浆380 μL,涡旋1 min,制成FCN-437c质量浓度分别为5、10、40、100、400、500、800、1 000 ng·mL-1的血浆标准溶液,按“2.4”项下方法处理后,再按“2.1”项下测定条件进样分析。以FCN-437c峰面积与FCN-437-D3峰面积之比Y为纵坐标,以FCN-437c质量浓度X为横坐标,用加权(W=1/X2)最小二乘法进行回归计算,拟合成标准曲线,得FCN-437c的回归方程:
结果显示,FCN-437c质量浓度在5~1 000 ng·mL-1线性良好,批间、批内准确度和精密度偏差<20%,定量限(信噪比≥10)为5 ng·mL-1,检测限(信噪比≥3)为1 ng·mL-1
用FCN-437c储备液(S2),配制成浓度为100、300、1 500、15 000 ng·mL-1(LLOQ、QC1~QC3)的工作液,取上述4个浓度的工作液20 μL置于1.5 mL塑料离心管中,分别加入空白血浆380 μL,涡旋1 min,制成FCN-437c浓度分别为5、15、75、750 ng·mL-1的血浆质控样品,按“2.4”项下方法处理后,再按“2.1”项下测定条件进样分析,每个质量浓度平行测定6份,根据同步操作制备的标准曲线计算样品中FCN-437c的实测浓度,同法连续测定3批,计算批内和批间准确度(RE)和精密度(RSD)。结果显示批内及批间准确度和精密度良好,满足生物样本定量分析的要求。结果见表2
取15份来源不同的空白血浆(包含9份正常血浆、3份溶血血浆、3份高脂血浆),按“2.4”项下方法处理(不加入FCN-437-D3)得到空白基质,加入低、中、高质量浓度的FCN-437c工作液及FCN-437-D3溶液,配制成浓度为15、75、750 ng·mL-1的血浆样品,每个浓度平行制备15个样品,按“2.1”项下测定条件进样分析,记录FCN-437c与FCN-437-D3峰面积。取等量的相同3个浓度的FCN-437c工作液及FCN-437-D3溶液,用溶剂稀释至同浓度,每个浓度平行制备6个样品,同法分析测定,记录FCN-437c与FCN-437-D3峰面积。按下列公式计算基质效应,基质因子=含基质溶液样品峰面积/不含基质(纯溶液)样品峰面积×100%;内标归一化基质因子=化合物基质因子/内标基质因子×100%。结果显示无明显基质效应(表3),生物基质对FCN-437c定量分析的影响有限。
按“2.4”项下方法配制FCN-437c低、中、高浓度(15、75、750 ng·mL-1)的血浆质控样品,每个浓度平行制备6个样品,按“2.1”项下测定条件进样分析,记录FCN-437c与FCN-437-D3峰面积。按“2.4”项下方法处理空白血浆(不加入FCN-437-D3)得到空白基质,加入FCN-437c工作液及FCN-437-D3溶液,配制FCN-437c低、中、高浓度(15、75、750 ng·mL-1)的血浆样品,每个浓度平行测定6份,按“2.1”项下测定条件进样分析,记录FCN-437c与FCN-437-D3峰面积。计算提取回收率=血浆质控样品经处理后所测得峰面积平均值/空白基质处理后加等量药物所测得峰面积平均值×100%。结果显示FCN-437c和FCN-437-D3的提取回收率稳定,满足生物样本定量分析的要求。结果见表3
按“2.4”项下方法配制高浓度的FCN-437c血浆质控样品(500、1 500、7 500 ng·mL-1),并用空白血浆基质稀释该样品10倍,按“2.1”项下测定条件进样分析,每个浓度平行测定6份。测得准确度为108.0%、103.0%、102.0%,精密度为2.5%、4.5%、2.4%。结果表明10倍稀释后不影响准确度和精密度。
按“2.3”项下方法配制FCN-437c的储备液,在4 ℃下存202 d;按“3.3”项下方法配制FCN-437c工作液(5、1 000 ng·mL-1),在室温下存放24 h;按“3.4”项下方法配制FCN-437c低、中、高质量浓度(15、75、750 ng·mL-1)的血浆样品,分别于处理前在室温放置20 h、-20 ℃放置134 d、-80 ℃放置662 d、-80 ℃~室温循环冻融3次、自动进样器(10 ℃)中放置24 h;全血中加入FCN-437c工作液,在室温下放置4 h后离心获得血浆,按“2.4”项下方法处理后进样分析,每个浓度平行测定不少于4份,考察稳定性,RSD均小于7%。结果表明,在上述条件下FCN-437c稳定性好。
分析批使用的内标为待测物的稳定同位素内标,且保留时间与待测物相同。需确保FCN-437-D3具有足够高的同位素纯度,并且不发生同位素交换反应,以避免检测的干扰,导致结果的偏差。配制高浓度的FCN-437c样品(不加FCN-437-D3)进样分析,内标通道产生的干扰峰的峰面积与内标平均峰面积比小于小于5%,结果显示FCN-437c对FCN-437-D3检测无影响。在每批次检测中,均随行进样QC0样品(空白血浆加FCN-437-D3),FCN-437c通道峰面积均为0。结果显示,FCN-437-D3对FCN-437c检测无影响,FCN-437-D3溶液4 ℃放置127 d内未发生同位素交换,FCN-437-D3溶液稳定。
研究样本进行重复分析,ISR样品量为总样品量的11.8%,且样品的选择覆盖药动学曲线,计算初始浓度和再分析浓度的偏差。结果显示,97.0%的ISR样品测试结果与初测值的偏差在±20%以内,表明本分析方法重现性好。
采用上述检测方法,应用于FCN-437c首次临床研究。其中12例受试者口服FCN-437c 200 mg后体内FCN-437c血药浓度-时间曲线线性图见图3,主要药代参数见表4。与单次给药相比,第21天时,RAUC0-24RC max的累积比几何平均值为1.33倍与1.59倍。与结构类似物Ribociclib比较,FCN-437c 200 mg剂量组暴露水平高于Ribociclib 400 mg剂量组,接近于Ribociclib 600 mg剂量组的暴露水平[17]
FCN-437c是一种口服、强效、高选择性、全新结构的CDK4/6 抑制剂类抗肿瘤新药,本研究建立了一种灵敏可靠的定量分析人血浆中FCN-437c浓度的HPLC-MS/MS方法,并应用于晚期乳腺癌绝经后女性患者中的临床研究。FCN-437c虽然与其他CDK4/6抑制剂(诸如palbociclib、ribociclib、abemaciclib)结构类似,但色谱行为表现有较大差异。本研究在方法开发前期参考其他CDK4/6抑制剂的检测方法选择的条件,均无法形成特征性的色谱峰。最后根据FCN-437c自身性质,比较在不同填料的色谱柱上的保留行为后,采用了最佳的YMC Triart PFP色谱柱,通过其疏水性、π-π相互作用、偶极-偶极、立体选择性等多个保留机制,提高了待测物色谱保留。同时,根据流动相中有机相比例增加,待测物色谱保留增强的特点,采用了水相逐渐增加的梯度洗脱方法,获得最佳的色谱峰。检测前考察单独FCN-437c样品与FCN-437-D3样品,确保FCN-437c与FCN-437-D3之间不产生干扰。血浆样品采用蛋白沉淀法,血浆用量小,制备方法简便。对上述方法的选择性、线性、精密度和准确度、基质效应、提取回收率、稳定性等进行了验证,结果表明:该方法简单、可靠、灵敏、耐用。符合现行的中国药典2020年版附录9012关于生物分析方法验证的要求[18]
