用单克隆抗体17-1A(IgG 2A)治疗10例转移性结直肠癌患者。输注前,将MAb与分离的自体血单核细胞体外孵育。以重复疗程(2-4次)给予治疗,最大剂量为1000 mg MAb 17-1A。1例患者达到临床完全缓解,2例患者有轻微反应,1例患者病情稳定5个月。4名应答者的中位生存期为19个月,而6名无应答者的中位生存期为7个月。治疗耐受性良好。在该系列中,给予32次单克隆抗体17-1A输注。MAb 17-1A的血清半衰期约为22小时。所有患者均产生IgG和IgM类抗小鼠抗体。未观察到不良反应与抗小鼠抗体之间的关系。3次观察到过敏反应。MAb 17-1A皮肤试验似乎可以可靠地预测过敏反应。
Ten patients with metastatic colorectal carcinoma were treated with MAb 17-1A (IgG2A). Before infusion, MAb was incubated in vitro with isolated autologous blood mononuclear cells. Treatment was given in repeated courses (2-4 times) to a maximum dose of 1000 mg of MAb 17-1A. One patient achieved a clinical complete remission, two patients had a minor response and one patient had stable disease for 5 months. The median survival for the four responders was 19 months compared to 7 months for the six non-responders. Therapy was well tolerated. In this series, 32 infusions of MAb 17-1A were given. The serum half-life of MAb 17-1A was approximately 22 hours. All patients developed anti-mouse antibodies of both IgG and IgM classes. No relation between adverse reactions and anti-mouse antibodies was seen. At 3 occasions allergic reactions were noted. Skin test with MAb 17-1A seems to reliably predict for allergic reactions.
IgG2A 单克隆抗体对人类肿瘤生长的抑制作用与肿瘤细胞上的抗体密度相关。
