ORAL01.01 - Randomized Phase III Study of Nedaplatin plus Docetaxel versus Cisplatin plus Docetaxel for Advanced Squamous Cell Lung Cancer (WJOG5208L) (ID 621)
10:45 - 12:15 | Author(s): T. Maeda
Nedaplatin (N) is a second-generation platinum compound with lower nausea/vomiting and nephrotoxicity than cisplatin (C). Nedaplatin plus docetaxel (ND) showed a promising efficacy with acceptable toxicity for advanced squamous cell lung cancer (SqLC) in the previous phase II study.
Eligible patients (pts) were those with pathologically proven SqLC with stage IIIB/IV or postoperative recurrence, aged 20-74 years and ECOG PS 0-1. Pts were randomized 1:1 to ND (N 100 mg/m and docetaxel (D) 60mg/m iv, q3w, up to 6 cycles) or C plus D (CD) (C 80 mg/m and D 60mg/m iv, q3w, up to 6 cycles) according to stage, gender and institution. The primary endpoint was overall survival (OS), and secondary endpoints included progression-free survival (PFS), response rate (RR) and adverse events (AEs). Target sample size of 350 provided 90% statistical power to detect a hazard ratio of 0.71 with one-sided type I error of 0.05.
Between July 2009 and July 2012, 355 pts were randomized. Of 349 for efficacy analysis (ND 177; CD 172), baseline characteristics were well-balanced between two arms. ND had a significantly longer OS (p=0.037, one-sided stratified log-rank test). The OS HR was 0.81 (90%CI, 0.67-0.98) with a median OS of 13.6 months [m] for ND and 11.4 for CD. ND had a longer PFS (p=0.050) with a HR of 0.83 (0.69-1.00) and a median PFS of 4.9 m in ND and 4.5 in CD. RR was 54.5% in ND vs 52.9% in CD (p=0.829). Grade 3 or higher AEs of nausea (4.0% vs 14.3%), fatigue (3.4% vs 10.9%), hyponatremia (13.6% vs 30.3%) and hypokalemia (2.3% vs 8.6%) are more frequent in CD. Grade 3 or higher AEs of neutrophils (82.5% vs 70.3%) and platelets (9.0% vs 0.0%) are more frequent in ND, but there was no difference in grade 3 or higher febrile neutropenia (13.6% vs 15.4%). Treatment related deaths occurred in 4 and 3 pts in ND and CD, respectively.
ND showed a significantly longer OS as compared to CD with different toxicity profile. ND will be considered as a new standard treatment for advanced or relapsed SqLC. Clinical trial information: UMIN000002015.
