背景。血管紧张素 - (1-7)[血管紧张素(1-7)]是一种内源性抗血管生成激素具有抗癌活性。在血管紧张素的I期研究(1-7),二生三患有转移性肉瘤经历病情稳定。该II期临床研究临床研究和生物标志物的结果为治疗转移性肉瘤。
方法。Ang-(1-7) was administered by subcutaneous injection at a dose of 20 mg daily. If excessive toxicities occurred in the first cohort, a dose deescalation cohort was allowed. Blood samples were obtained to measure changes in biomarkers.
结果。治疗耐受性良好,并没有所需的剂量deescalation队列。治疗后血浆PlGF的浓度没有统计学显著改变。在注射后4小时,观察到血浆中血管紧张素甲显著增加(1-7)。中位无进展生存期为2.7个月(95%CI,1.4至4.1个月),中位总生存期为10.2个月(95%CI,5.3至18.3个月)。两个患者的血管肉瘤证实延长为10个月(血管外皮细胞瘤)和19个月(上皮样血管内皮瘤)病情稳定。
结论。Ang-(1-7) at a dose of 20 mg daily was well-tolerated. This prospective phase II study failed to confirm the PlGF biomarker effect identified in the prior phase I study. Prolonged disease stabilization in hemangiopericytoma and epithelioid hemangioendothelioma may warrant further investigation.
