In this phase II study, patients with stage IIIB/IV non-small-cell lung cancer were randomly assigned (1:1:1) to receive LY293111 (200 mg twice daily [200 LY293111] or 600 mg twice daily [600 LY293111]) or placebo for 7 days, followed by concurrent cisplatin (75 mg/m2; day 1) and gemcitabine (1250 mg/m2; days 1 and 8), every 21 days.The primary endpoint was progression-free survival, (PFS), with 75% power to detect 33% improvement compared with placebo (5 months).


Of 200 randomized patients, 195 were treated. Demographics were well balanced across treatment arms: 65% of the patients were men; median age was 62 years; 85% had stage IV disease; and patients had an Eastern Cooperative Oncology Group performance status of 0 (36%) or 1 (64%).


The most frequent study drug-related toxicities were nausea, vomiting, and fatigue. Response rates were similar across treatment arms (200 LY293111: 20%; 600 LY293111: 25%; placebo: 31%).


Median PFS (95% confidence interval) was not significantly different across treatment arms (200 LY293111: 4.6 months [3.2-5.0]; 600 LY293111: 5.6 months [4.1-6.8]; placebo: 6.0 months [5.2-7.5]). LY293111 combined with gemcitabine-cisplatin did not increase median PFS compared with placebo plus gemcitabine-cisplatin in patients with non-small-cell lung cancer.
