抗IL-17A单克隆抗体药物的质量控制
Quality control of anti⁃IL⁃17A monoclonal antibody drug
目的 研究并建立针对抗白细胞介素(IL)-17A单抗关键质量属性的质控方法。 方法 采用生长相关基因α(GRO α)细胞因子生物学活性测定法检测生物学活性;采用反相色谱测定肽图谱,采用毛细管等电聚焦电泳(cIEF)测定等电点,采用还原/非还原十二烷基硫酸钠毛细管凝胶电泳(CE-SDS)、分子排阻色谱(SEC-HPLC)进行单抗纯度的测定;运用离子交换色谱(IEC-HPLC)测定电荷异质性;运用亲水-超高效液相色谱(HILIC-UPLC)分析抗IL-17A单抗的糖基化;采用ELISA法检测IL-17A结合活性。 结果 抗IL-17A单抗的生物学活性的半数最大效应浓度(EC50)值为(6.70±1.19)ng/mL;IL-17A结合活性的EC50值为(35.60±3.70)ng/mL;cIEF检测的主峰等电点为7.30±0.004;非还原CE-SDS主峰面积百分比为(96.95±0.12)%,还原CE-SDS重链(HC)和轻链(LC)的峰面积百分比之和为(98.38±0.11)%;SEC-HPLC主峰面积百分比为(99.55±0.01)%;离子交换色谱中主峰面积百分比为(73.07±0.12)%,酸性峰面积百分比为(16.52±0.05)%,碱性峰面积百分比为(10.41±0.10)%;N-聚糖分析中高甘露糖基化5单糖所占比例为(1.96±0.03)%,岩藻糖基化所占比例为(88.69±0.44)%,半乳糖基化单糖所占比例为(11.96±0.03)%。 结论 本研究成功建立了抗IL-17A单抗关键质量属性的质量控制分析方法,可用于该类单抗产品的质量控制。
Objective To establish quality control methods for key quality attributes(KQAs) of anti-interleukin 17A(IL-17A) monoclonal antibodies(mAbs). Methods The biological activity was determined by GROα cytokine bioactivity assay. Peptide mapping was analyzed by reverse-phase chromatography. The isoelectric point was measured by capillary isoelectric focusing electrophoresis(cIEF). Purity was evaluated by reduced/non-reduced capillary electrophoresis-sodium dodecyl sulfonate(CE-SDS) and size exclusion-high performance liquid chromatography(SEC-HPLC). Charge heterogeneity was assessed by ion exchange chromatography(IEC-HPLC). Glycosylation of anti-IL-17 mAb was analyzed by hydrophilic-ultra high performance liquid chromatography(HILIC-UPLC). The binding activity of IL-17A was detected by ELISA. Results The half maximal effective concentration(EC50) for the biological activity of anti-IL-17A monoclonal antibodies was (6.70±1.19)ng/mL. The EC50 of IL-17A binding activity was (35.60±3.70)ng/mL. The main peak isoelectric point determined by cIEF was 7.30±0.004. The percentage of main peak area by non-reduced CE-SDS was (96.95±0.12)%, and the sum of peak area percentages of heavy chain(HC) and light chain(LC) in reduced CE-SDS was (98.38±0.11)%. The percentage of main peak area by SEC-HPLC was (99.55±0.01)%. In ion exchange chromatography, the percentage of main peak area was (73.07±0.12)%, the percentage of acidic peak area was (16.52±0.05)%, and the percentage of basic peak area was (10.41±0.10)%. In N-glycan analysis, the total proportion of high-mannose glycosylation 5 monosaccharides was (1.96±0.03)%, the total proportion of fucosylation was (88.69±0.44)%, and the total proportion of galactosylation monosaccharides was (11.96±0.03)%. Conclusion Quality control analytical methods for the critical quality attributes(CQAs) of the anti-IL-17A monoclonal antibody have been successfully established, and can be applied to the quality control of this category of monoclonal antibody products.
