To evaluate activity and safety of obinutuzumab-miniCHOP (Ga101-miniCHOP) combination in older patients with Diffuse Large B-Cell Lymphoma (DLBCL) unfit to receive full dose immunochemotherapy.
We conducted a Simon's two-stage phase II multicenter trial to investigate response rate (primary endpoint) and safety of six courses of Ga101-miniCHOP in older patients with DLBCL (≥65 years), prospectively defined as unfit according to a simplified Comprehensive Geriatric Assessment (sCGA).
Overall, 34 patients were enrolled (median age 82 years; range 68-89), with 27 out of the 33 eligible patients completing all six planned courses. Complete Remission (CR) rate was reported in fourteen patients (42%). After a median follow-up of sixteen months, the two-year Progression Free and Overall Survival (PFS and OS) were 49% (95% Confidence Interval (CI), 28 to 67) and 68% (95% CI, 49 to 81), respectively. The most frequent grade 3-4 adverse event was neutropenia in thirteen patients (26%).
Based on the observed CR rate, study accrual was interrupted due to the very low probability of demonstrating the initial study hypothesis that Ga101-miniCHOP could improve results of historical data obtained with R-miniCHOP in this group of patients. Nonetheless, results achieved with the 33 treated patients confirm activity and good tolerability of the Ga101-miniCHOP regimen for older unfit adult patients with DLBCL.
评估奥妥珠单抗-小剂量CHOP方案(Ga101-小剂量CHOP)用于不适合接受全剂量免疫化疗的老年弥漫性大B细胞淋巴瘤(DLBCL)患者的活性及安全性。
我们开展了一项西蒙两阶段II期多中心试验,以研究Ga101-小剂量CHOP方案六个疗程用于老年DLBCL患者(≥65岁)的缓解率(主要终点)及安全性,根据简化综合老年评估(sCGA)前瞻性地定义为不适合接受全剂量免疫化疗。
总体上,共纳入34例患者(中位年龄82岁;范围68 - 89岁),33例符合条件的患者中有27例完成了所有六个计划疗程。14例患者(42%)报告达到完全缓解(CR)。中位随访16个月后,两年无进展生存率和总生存率(PFS和OS)分别为49%(95%置信区间(CI),28%至67%)和68%(95% CI,49%至81%)。最常见的3 - 4级不良事件是13例患者(26%)出现的中性粒细胞减少。
基于观察到的CR率,由于证明Ga101-小剂量CHOP方案可改善该组患者采用R-小剂量CHOP方案获得的历史数据这一初始研究假设的可能性非常低,研究入组被中断。尽管如此,33例接受治疗患者所取得的结果证实了Ga101-小剂量CHOP方案对于不适合接受全剂量免疫化疗的老年DLBCL成年患者具有活性且耐受性良好。
