摘要
背景:nab -紫杉醇是晚期胃癌的标准二线治疗,但PD-1抑制剂的作用仍不确定。这项多中心、随机II期试验评估了nab-紫杉醇联合camrelizumab (Cam-NP)与nab-紫杉醇单用(NP)治疗对既往治疗耐药的晚期胃腺癌患者的疗效。方法:患者随机接受Cam-NP或NP治疗,直到疾病进展、无法忍受的毒性或同意退出。主要终点是总缓解率(ORR),次要终点包括无进展生存期(PFS)、总生存期(OS)和安全性。结果:61例患者随机分组,其中58例接受治疗。在中位随访34.5个月时,Cam-NP组的ORR显著提高(33.3% vs. 10.7%;p = 0.039)和更长的中位PFS (5.62 vs 4.21个月;P = 0.006)。中位反应持续时间也有利于Cam-NP(4.64个月vs 2.96个月;P = 0.058)。而Cam-NP组的OS较长(9.8个月vs. 7.2个月;P = 0.087),差异无统计学意义。最常见的3-4级不良事件是血液毒性。结论:与NP相比,Cam-NP作为晚期胃腺癌的二线治疗可显著改善ORR和PFS。需要更大规模的研究和生物标志物探索来验证这些发现。
Multi-Center Phase II Study of Nab-Paclitaxel Plus Camrelizumab Versus Nab-Paclitaxel Alone as Second-Line Treatment for Advanced Gastric Cancer.
Background: Nab-paclitaxel is a standard second-line treatment for advanced gastric cancer, but the role of PD-1 inhibitors remains uncertain. This multicenter, randomized phase II trial evaluated the efficacy of nab-paclitaxel plus camrelizumab (Cam-NP) versus nab-paclitaxel alone (NP) in patients with advanced gastric adenocarcinoma resistant to prior treatment.
Methods: Patients were randomized to receive either Cam-NP or NP until disease progression, intolerable toxicity, or consent withdrawal. The primary endpoint was the overall response rate (ORR), with secondary endpoints including progression-free survival (PFS), overall survival (OS), and safety.
Results: 61 patients were randomized, with 58 receiving treatments. At a median follow-up of 34.5 months, the Cam-NP group achieved a significantly higher ORR (33.3% vs. 10.7%; p = 0.039) and longer median PFS (5.62 vs. 4.21 months; p = 0.006). Median response duration also favored Cam-NP (4.64 vs. 2.96 months; p = 0.058). While the Cam-NP group showed a longer OS (9.8 vs. 7.2 months; p = 0.087), this was not statistically significant. The most common grade 3-4 adverse event was hematological toxicity.
Conclusions: Cam-NP significantly improved ORR and PFS compared to NP as a second-line treatment for advanced gastric adenocarcinoma. Larger studies and biomarker exploration are needed to validate these findings.
