Lung cancer is the leading cause of cancer death in the U.S. and most other countries, and non-small cell lung cancer accounts for 85 percent of all lung cancer cases. It is estimated that approximately half of NSCLC patients are receiving treatment in the second-line setting. Despite currently available therapies, there continues to be a need for new second-line treatment options for patients with NSCLC.
"While there have been other recent Phase III studies that have evaluated the addition of a cytotoxic or targeted agent in previously-treated NSCLC patient populations, none have demonstrated improved overall survival in the total patient population," said
The global, randomized, double-blind REVEL trial compared CYRAMZA plus docetaxel to placebo plus docetaxel in NSCLC patients with progression after platinum-based chemotherapy for locally-advanced or metastatic disease. The international study included a total of 1,253 nonsquamous and squamous NSCLC patients from 26 countries on six continents. Overall survival (OS) was the trial's primary endpoint and secondary endpoints included progression-free survival (PFS) and objective response rate (ORR).
Patients treated on the CYRAMZA-plus-docetaxel arm (n=628) achieved a median OS of 10.5 months compared to 9.1 months for patients on the placebo-plus-docetaxel arm (n=625). The OS hazard ratio was 0.86 (95% CI, 0.751-0.979, p=0.023), which corresponds to a 14 percent reduction in risk of death.
Median PFS was 4.5 months on the CYRAMZA-plus-docetaxel arm compared to 3.0 months on the placebo-plus-docetaxel arm, with a PFS hazard ratio of 0.76 (p
"In the REVEL study, CYRAMZA demonstrated statistically significant improvement across multiple efficacy endpoints including overall survival, progression-free survival and overall response rate. The improvement of overall survival and progression-free survival on the CYRAMZA-plus-docetaxel arm was also consistent across the majority of subgroups including histology," said
The most common (>5% incidence) Grade >/=3 adverse events occurring more frequently in patients on the CYRAMZA arm were neutropenia (48.8% vs. 39.8%), febrile neutropenia (15.9% vs. 10.0%), fatigue (14.0% vs 10.5%), leukopenia (13.7% vs. 12.5%), and hypertension (5.6% vs. 2.1%). Grade 5 adverse events were comparable between arms (5.4% vs. 5.8%). Patients on the CYRAMZA arm experienced more bleeding/hemorrhage events (all grade) (28.9 % vs 15.2%) but the rate of Grade >/=3 bleeding / hemorrhage events were similar between arms (2.4% vs 2.3%).
Dr. Perol presented the REVEL data at ASCO and
Lilly intends to submit the first application of these data to regulatory authorities in the second half of 2014.
