M-PRP 细胞含量非格司亭与 Pegfilgrastim 的质量和数量比较 (M-PRP)
比较使用非格司亭与 Pegfilgrastim 外周动员祖细胞后收获的 M-PRP 细胞含量的单中心前瞻性研究
这项前瞻性观察性研究的目的是比较在给予两种细胞刺激蛋白非格司亭和聚乙二醇非格司亭之一后收获的富含血小板血浆的细胞含量的质量和数量。 它旨在回答的主要问题是:
• 将4 天非格司亭治疗与1 天培非格司亭治疗进行比较时,参与者的细胞含量是否相似?
参与者将接受以下干预:
- 在同意后的第一次访问和治疗后的后续访问中将抽取 130mL 血液(非格司亭 4 天,培非格司亭 7 天)
- 所有参与者中的一半将首先接受非格司亭,然后在非格司亭治疗结束后 8 周接受培非格司亭。 另一半将以相反的顺序接受治疗
研究人员将在每次治疗后比较细胞含量的质量和数量,并根据给予的治疗顺序比较数据差异。
研究概览
详细说明
拟议的研究是一项前瞻性、随机对照、单中心实验室研究,涉及 10 名健康志愿者。 一旦潜在参与者通过筛选、同意研究程序、完成医学访谈和实验室血液检测,受试者将经历两次系列动员活动。 动员活动的安排将因 10 名参与者而异,以抵消动员活动的顺序效应。 5 名健康供体将接受每天 10 mcg/kg 的标准非格司亭动员方案共 4 天。 随后将进行标准的聚乙二醇聚乙二醇动员方案,其中包括一次 6 毫克注射,间隔 8 周,供 5 名参与者使用。 其他 5 名健康供体将接受药剂的相反顺序,首先是聚乙二醇非格司亭,然后是非格司亭。
在研究的第一天,将进行 130 mL 的第一次抽血,这将用于创建用于实验室测试的标准 PRP,并且受试者将开始非格司亭或培非格司亭剂量系列。 在指定时间后(非格司亭 4 天,培非格司亭 7 天),将采集第二份 130 mL 血液并使用 Arthrex Angel 系统进行处理,以创建用于实验室测试的 M-PRP。 标准 PRP 和 M-PRP 细胞含量将通过细胞计数、细胞培养和蛋白质分析在体外进行研究和量化。 第二次采血后 8 周,受试者将返回进行第三次 130 mL 血液抽取,然后施用第二种动员剂(pegfilgrastim 或 filgrastim)。 在指定时间后(非格司亭 4 天,培非格司亭 7 天),患者将返回进行第四次 130mL 抽血。 该样本将使用 Arthrex Angel 系统进行处理,以创建用于实验室测试的 M-PRP。 M-PRP 产品的细胞含量将通过细胞计数、细胞培养和蛋白质分析在体外进行研究和量化。 此后,将在非格司亭和培非格司亭动员剂之间比较 M-PRP 产品的细胞含量。
