Severity graded by NCI-CTCAE V.4.0.
*Includes events occurring during treatment through the 30-day post-treatment follow-up period.
†The number of drug-related TEAEs can be larger than the number of TEAEs for a given grade because a patient is counted only once for each category. In the overall summary of TEAEs, a patient is counted once in the category of worst grade regardless of relationship to study drug. To find the drug-related TEAEs, a subset is first generated for any TEAEs that are drug related, and then the patient is counted once in the worst grade category. For a given patient, the worst grade of drug-related TEAEs may be different than the worst grade of overall TEAEs.
‡The grade 5 regorafenib-related TEAEs were pulmonary embolism (1), malaise (as reported by the investigator) (1), sepsis (1) and thromboembolic event (1).
§Dose modifications include delays, reductions and interruptions.
