Lancet oncol:派姆单抗治疗儿科各类肿瘤的疗效

2019-12-13 QQY MedSci原创

派姆单抗已被批准用于治疗成人晚期癌症,但尚无派姆单抗用于儿科癌症患者的疗效和安全性的相关信息。现研究人员开展一项1-2期开放性研究,以明确派姆单抗用于晚期小儿癌症推荐的2期剂量、安全性和抗肿瘤活性。从多个国家的30家医院招募6-17岁的黑色素瘤或PD-L1阳性的复发性或难治性实体肿瘤或淋巴瘤患儿,要求Lansky Play/Karnofsky表现状态评分≥50,予以派姆单抗 静脉注射,初始剂量2m

派姆单抗已被批准用于治疗成人晚期癌症,但尚无派姆单抗用于儿科癌症患者的疗效和安全性的相关信息。

现研究人员开展一项1-2期开放性研究,以明确派姆单抗用于晚期小儿癌症推荐的2期剂量、安全性和抗肿瘤活性。从多个国家的30家医院招募6-17岁的黑色素瘤或PD-L1阳性的复发性或难治性实体肿瘤或淋巴瘤患儿,要求Lansky Play/Karnofsky表现状态评分≥50,予以派姆单抗 静脉注射,初始剂量2mg/kg·3周。主要结点是测定最大给药剂量时的剂量限制性毒性、安全性和耐受性,以及每种肿瘤对派姆单抗有客观反应的患者比例。

2015年3月23日-2018年9月3日,共筛选了863位患儿,796位进行了PD-L1表达水平的评估(278位[35%]为PD-L1阳性),155位(中位年龄13岁[IQR 8-15])进入试验,154位患儿至少接受了一剂量的派姆单抗治疗。中位随访8.6个月(IQR 2.5-16.4)。在1期,未发生剂量限制性毒性,派姆单抗血浆浓度与在成人中的报道一致;推荐的2期剂量是2mg/kg·3周。对于154位进行治疗的患儿,69位(45%)患儿发生3-5级副作用事件,最常见的是贫血(14位[9%])和淋巴细胞计数减少(9位[6%])。13位(8%)患儿发生3-5级治疗相关的副作用事件,最常见的是淋巴细胞计数减少(3[2%])和贫血(2[1%])。14位(9%)患儿发生重度治疗相关副作用事件,最常见的是发热(4[3%])和高血压与胸腔积液(2[1%])。4位(3%)患儿因治疗相关副作用事件终止治疗,2位(1%)患儿死亡(1位因为肺水肿、1位因为胸腔积液和肺炎)。15位复发性或难治性霍奇金淋巴瘤患儿,2位完全缓解,7位部分缓解;因此,9位患儿获得客观缓解(60.0%,95% CI 32.3-83.7)。对于136位实体瘤和其他淋巴瘤患儿,8位获得部分缓解(2位肾上腺皮质癌和间皮瘤,恶性神经节神经胶质瘤、上皮样肉瘤、淋巴上皮癌和恶性横纹肌样瘤各1例);客观缓解患者比例5.9%(95% CI 2.6-11.3)。

派姆单抗用于复发性或难治性霍奇金淋巴瘤患儿的耐受性良好,而且表现出抗肿瘤活性,与用于成人患者的相似。对于大部分儿科肿瘤,派姆单抗的抗肿瘤活性较低,仅在少数罕见的PD-L1阳性肿瘤类型中观察到缓解,提示仅以PD-L1表达作为选择可能对PD-1检查抑制剂有反应的患儿的生物标志物是不够的。

J Clin Oncol:派姆单抗治疗难治性转移去势抵抗性前列腺癌研究

之前的研究报道了派姆单抗对程序性死亡配体1(PD-L1)阳性转移去势抵抗性前列腺癌(mCRPC)具有抗肿瘤活性。最近,有研究人员评估了派姆单抗在一个更大的mCRPC群体中的3个平行群体中的抗肿瘤活性和安全性情况。研究共包括了258名患者:群体1中包含133名,群体2中包含66名,群体3中包含59名。群体1中客观反映率为5%(95% CI, 2%到11%),群体2中客观反映率为3%(95% CI,
