MP0250的结构

MP0250是一种DARPin候选药物,可特异性抑制血管内皮生长因子(VEGF)和肝细胞生长因子(HGF),以破坏肿瘤微环境。

本试验(I期)是MP0250的首次人体研究,旨在评估MP0250用于晚期实体肿瘤的安全性、耐受性和药代动力学。在剂量递增队列中,24位患者接受5个剂量水平(0.5-12mg/kg)的MP0250治疗,3小时静脉输液,2周一次;最大耐受剂量(MTD)明确后,21位患者采用1小时输液法接受MP0250治疗(剂量确认队列)。

MP0250的代谢

在剂量递增队列,接受12 mg/kg剂量治疗的患者出现了剂量限制性毒性。因此,MP0250的最大耐受剂量定为8 mg/kg·2周或12 mg/kg·3周

最常见的不良反应(AE)有高血压(69%)、蛋白尿(51%)、腹泻(36%)和恶心(36%);24%的患者报告了低白蛋白血症。大部分不良反应与VEGF和HGF通路抑制一致。所有患者在整个给药期间的暴露均与剂量成正比。半衰期约2周。

有观察到单药抗肿瘤活性:1例未确认的部分缓解,23周后病情进展,有24例病情稳定,病情稳定最长72周,中位持续稳定时间为18周。

总之,MP0250是一线DARPin候选药物,耐药性良好,药代动力学适宜,可进一步评估其与其他抗癌药物联合使用的效果。
