DLT is defined as an adverse event between Day -3 and Day 29 of Cycle 1 that is possibly related to the study drug and fulfills any one of the following criteria using the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03.

Urinary and Fecal Excretion of LY2835219-Related Radioactivity Over Time Expressed as a Percentage of the Total Radioactive Dose Administered
Predose up to Day 14 postdose; Fecal samples collected at 24-hour (h) intervals; Urine collected at 0 to 6 h, 6 to 12 h, and 12 to 24 h postdose and at 24-h intervals thereafter up to Day 14 postdose

The percentage of the total radioactive dose administered that was excreted in urine or feces = (amount of radioactive dose recovered in urine or feces / total radioactive dose administered) \* 100.
