Study Comments Two randomized controlled studies of patients with resected colon with an indicator of poor prognosis and no evidence of residual disease. Over 400 patients in the first study and over 1200 in the second were used for analysis of both efficacy and safety. Five Phase 2 studies were submitted to support approval.
Study Results In one clinical trial in which 408 Dukes' B and C colorectal cancer patients were studies, 262 Dukes' C patients were evaluated for a minimum follow-up of 5 years. A subset analysis of these Dukes' C patients showed the estimated reduction in death rate was 27% for LEV plus 5-FU (p=.11) and 28% for LEV alone (p=.11). In a confirmatory study 929 Dukes' C colon cancer patients were evaluated for a minimum follow-up of 2 years. The estimated reduction in death rate was 35% for LEV plus 5-FU (p=.0004). The estimated reduction in recurrence rate was 38% for LEV plus 5-FU (p=.0002). The LEV alone group did not show advantage over no treatment in improving recurrence or survival rates.
