OBJECTIVE To establish a quality control method of human chain-activated immune cell preparations. METHODS The ability to secrete cytokines and in vitro cytotoxicity were detected by co-culture and flow cytometry analysis. Purity was determined by flow cytometry. The concentration of live cells and cell viability were determined by AO/PI dual fluorescence cell counter. The residual cytokines were determined by enzyme-linked immunosorbent assay. Mycoplasma nucleic acid was detected by probe real-time PCR.Other detection items were carried out according to the provisions of the 3rd part of Chinese Pharmacopoeia 2020. RESULTS The detection of human chain-activated immune cell preparations was carried out using the established method,and the results of biological activity research, physical and chemical characteristics research, and cytokine residual detection were normally distributed. The detection results were valid,and the coefficient of variation(CV) was less than 20%. All other indicators met the requirements of the Chinese Pharmacopoeia 2020. CONCLUSION A preliminary quality control method of human chain-activated immune cell preparations are established, which has the characteristics of ensuring the quality control lability, safety, and effectiveness of the cell preparations. It can be used for the quality control of the human chain-activated immune preparations.

METHODS The ability to secrete cytokines and in vitro cytotoxicity were detected by co-culture and flow cytometry analysis. Purity was determined by flow cytometry. The concentration of live cells and cell viability were determined by AO/PI dual fluorescence cell counter. The residual cytokines were determined by enzyme-linked immunosorbent assay. Mycoplasma nucleic acid was detected by probe real-time PCR.Other detection items were carried out according to the provisions of the 3rd part of Chinese Pharmacopoeia 2020. RESULTS The detection of human chain-activated immune cell preparations was carried out using the established method,and the results of biological activity research, physical and chemical characteristics research, and cytokine residual detection were normally distributed. The detection results were valid,and the coefficient of variation(CV) was less than 20%. All other indicators met the requirements of the Chinese Pharmacopoeia 2020. CONCLUSION A preliminary quality control method of human chain-activated immune cell preparations are established, which has the characteristics of ensuring the quality control lability, safety, and effectiveness of the cell preparations.

人链式激活免疫细胞制剂系由患者自体外周血中的单个核细胞在体外经CD3联合细胞因子(Ⅰ、Ⅱ、Ⅲ)激活扩增培养而获得的混合T淋巴细胞[1-2]。这种经激活和诱导的免疫细胞可在患者体内对肿瘤细胞进行杀伤,配合放化疗或单独使用抑制原发肿瘤生长,从而达到延缓复发和转移,提高患者的生存质量[3-4]。随着生物医学技术的快速发展,免疫细胞治疗已经成为肿瘤治疗、自身免疫性疾病以及感染性疾病治疗的重要手段。然而,免疫细胞产品的制备过程复杂,涉及多种细胞类型的选择、激活、扩增和基因修饰等步骤,这些过程的微小变化都可能影响最终产品的质量和疗效。因此,免疫细胞的质量控制成为了确保治疗效果和患者安全的关键环节[5]
目前国内外关于细胞治疗和基因治疗产品的技术指导原则中对此有一些基本的叙述[6-7],例如对其关键质量参数的研究、产品的开发和质量控制的指导等[8-9]。为了能有效控制人链式激活免疫细胞制剂的质量,本研究根据国家药品监督管理局药品审评中心发布的《免疫细胞治疗产品临床试验技术指导原则(试行)》[10]结合国内外发布的一些参考文献,建立质量控制检测方法,对其开展质量研究,建立质量标准。

采用SPSS软件进行统计学分析,实验数据用均数±标准差表示。质量研究结果使用Shapiro-Wilk检验进行统计分析,检验观测值是否与预期的正态分布相符,以检测结果是否异常,当P值>0.05,则观测值与预期正态分布相符,检测正常,当P值≤0.05,则检测结果异常[18-19]
对12批次人链式激活免疫细胞制剂进行细胞因子分泌及体外杀伤活性检测,检测结果发现,细胞因子分泌检测结果平均值为77.81%,最低值为63.36%,变异系数(coefficient of variation,CV)为14.71%;体外杀伤活性检测结果的平均值为94.08%,最低值为90.55%,CV为2.77%。
细胞生物学活性质量研究数据经Shapiro-Wilk检验进行统计分析,细胞因子分泌检测的统计量W=0.947,P=0.590>0.05,体外杀伤活性检测的W=0.942,P=0.525>0.05,样本所来自的总体分布服从正态分布,认为检测结果数据服从正态分布,检测结果正常。
人链式激活免疫细胞制剂理化特性研究检测结果见表1,pH值、渗透压摩尔浓度、活细胞浓度、细胞活率的CV值分别为2.31%、2.27%、8.60%、2.94%,细胞纯度分析的各细胞亚群的CV值为2.05%~9.76%之间,CV值均小于10%。
Shapiro-Wilk检验结果显示,理化特性研究结果的P值均大于0.05(表2),说明与正态性没有统计学差异,认为检测结果数据服从正态分布,检测结果正常。
根据《中国药典》2020年版三部的要求,对12批次人链式激活免疫细胞制剂进行细菌内毒素检查、无菌检查、支原体检查等项目的检测,细菌内毒素检查结果均小于1 EU·mL-1,其他检查项目结果均符合规定;支原体核酸检测结果均为阴性与《中国药典》支原体检查结果一致。
人链式激活免疫细胞制剂杂质研究结果显示,细胞因子Ⅰ、Ⅱ和CD3抗体残留检测结果均低于定量下限,细胞因子Ⅲ残留结果低于100 pg·mL-1,见表3
人链式激活免疫细胞制剂保存至-196~-150 ℃条件下,放置9个月,进行长期试验研究。外观、pH、渗透压变化不大,内毒素、无菌符合规定,活细胞浓度、细胞活率、细胞纯度;细胞因子分泌稍有下降趋势,但均符合质量标准要求;杀伤效率稍有下降,但均符合质量标准要求,研究结果表明在-196~-150 ℃条件下至少可保存9个月(图2)。
人链式激活免疫细胞制剂冻存至-85~-60 ℃条件放置28 d,进行加速稳定性研究。细胞因子分泌和体外杀伤活性在第7天后呈明显下降趋势,理化特性及安全相关指标均符合规定,表明在-85~-60 ℃条件可放置7 d(图3)。
人链式激活免疫细胞制剂保存至-20 ℃,放置30 h,进行影响因素稳定性研究。结果显示,在保存24 h,细胞活率和0点相比呈明显下降趋势,结果不符合质量标准要求。表明-20 ℃对该制剂的保存影响较剧烈(图4)。
人链式激活免疫细胞制剂复苏后在室温放置0、4、8、24 h进行细胞浓度及活率检测。结果显示,在复苏后4 h内,活细胞浓度及活率和0点相比有轻微下降,但均在合格范围内;在8和24 h,呈明显下降趋势,不符合质量标准要求。表明该制剂复苏后4 h内稳定(图5)。
近年来,在国家政策、技术和市场的驱动下,细胞治疗产业蓬勃发展,展现巨大的发展前景,成为生物医药行业的新赛道。目前细胞治疗领域中,进展最快、临床获批最多的细胞药物是免疫细胞[20],截至2024年12月,我国已经批准5个细胞药物用于治疗B细胞淋巴瘤或者多发性骨髓瘤。细胞来源于人体,所以这些细胞样本具有高度个性化的特性[21],生产过程也会涉及多环节的质量和风险把控,这些特性对生产工艺的稳定性、一致性以及质量的可控性形成挑战[22-23]
本研究旨在评估人链式激活免疫细胞制剂的质量控制流程,以确保其安全性、有效性和一致性,这对于临床应用至关重要。为保证人链式激活免疫细胞制剂的质量,严格按照《免疫细胞治疗产品药学研究与评价技术指导原则(试行)》和《中国药典》2020年版三部、四部的有关要求,本研究设计了功能性研究实验、理化特性研究实验及安全性研究实验,对细胞制剂的多个质量属性进行了全面的评估。
通过细胞因子分泌、体外杀伤活性检测,结合细胞纯度分析,来综合研究细胞制剂的功能性,结果表明该试验设计能够体现人链式激活免疫细胞制剂的功能性情况。理化特性研究结果稳定,安全性研究结果均符合《中国药典》2020年版三部的要求。通过稳定性研究数据表明,人链式激活免疫细胞制剂在≤-150 ℃条件下至少可保存9个月;在-85~-60 ℃条件可放置7 d;-20 ℃对该制剂的保存影响较剧烈。为了确定免疫细胞制剂在解冻后的最佳使用时间窗口,以确保在临床应用中的有效性和安全性,为临床应用提供指导,进行了使用稳定性研究。该免疫细胞制剂在复苏室温放置4 h内,其生物学活性、理化特性及安全性等特性均符合要求。
尽管本研究提供了有关人链式激活免疫细胞制剂质量控制的重要思路,但也存在一些局限性。例如,样本量相对较小,且实验条件可能未能完全模拟临床应用的实际环境。未来的研究应包括更大规模的样本和更多样化的临床前模型,以进一步验证本研究的结果和结论。此外,随着细胞治疗技术的不断进步,未来的研究还应探索新的质量控制技术和生物标志物,以提高细胞制剂的安全性和有效性[24-25]
综上所述,根据国家药品监督管理局药品审评中心发布的《免疫细胞治疗产品药学研究与评价技术指导原则(试行)》和《中国药典》2020年版三部、四部的有关要求,本研究初步建立了人链式激活免疫细胞制剂的质控方法和质量标准,并用于申报临床试验研究,为保证该产品安全有效、质量可控奠定了一定基础。
随着免疫细胞治疗产品的多样化和复杂性增加,质量控制和非临床研究的重要性日益凸显。这包括对细胞制剂的采集、处理、培养、收获以及最终产品的储存和运输等各个环节的严格控制。未来的免疫细胞治疗可能会更加个性化和精准化,通过深入理解细胞的生物学特性和疾病机制,开发出更加个性化的细胞治疗方案。同时,随着技术的进步,免疫细胞治疗的适应证可能会进一步拓宽,包括实体瘤和自身免疫性疾病的治疗。
尽管免疫细胞治疗在某些类型的癌症治疗中显示出巨大的潜力,但仍面临诸如治疗抵抗、不良反应管理以及如何提高疗效等挑战。未来的研究需要进一步探索这些挑战,并开发新的策略和技术来克服。免疫细胞治疗正成为癌症治疗的一个重要方向,其质量控制对于确保治疗的安全性和有效性至关重要。
