LY2603618

Overall response rate is the best response of complete response (CR) or partial response (PR) as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST v1.1). CR is a disappearance of all target and non-target lesions and normalization of tumor marker level. PR is an at least 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameter) without progression of not-target lesions or appearance of new lesions. Overall response rate is calculated as a total number of participants with CR or PR divided by the total number of participants with at least 1 measurable lesion, multiplied by 100.

DLT is defined as adverse event (AE) during Cycle 1 (Days 1 through 28) that was possibly related to the study drug and toxicities considered by the investigator as dose limiting. A summary of other nonserious AEs, and all serious adverse events (SAE's), regardless of causality, is located in the Reported Adverse Events section.

Progression-free survival (PFS) time is defined as the time from the date of randomization to the first date of documented objective progressive disease (PD) or death from any cause. For participants who were not known to have had objective PD as of the data inclusion cut-off date for a particular analysis, PFS was censored at the date of the last objective progression-free disease assessments. For participants who took any subsequent systemic anticancer therapy prior to progression, PFS was censored at the date of the last objective progression-free disease assessment prior to the start date of any subsequent systemic anticancer therapy. PFS time was summarized using Kaplan-Meier estimates.

The recommended Phase 2 dose for LY2603618 when administered approximately 24 hours after pemetrexed and cisplatin was based on the maximum tolerated dose (MTD) and achievement of predefined LY2603618 plasma systemic exposures targets (area under the LY2603618 plasma concentration versus time curve from time zero to infinity \[AUC(0-∞)\] \>21,000 nanogram\*hour/milliliter \[ng\*h/mL\] and maximum LY2603618 plasma concentration \[Cmax\] \>2000 nanograms/milliliter \[ng/mL\]).

Urinary and fecal excretion samples from each participant were measured by liquid scintillation counting. The radioactive counts detected in urine and fecal samples were each divided by the theoretical radioactive count in the total radioactive dose administered and multiplied by 100% to arrive at a percentage of total radioactive dose excreted in urine and feces.

The recommended Phase 2 dose for LY2603618 when administered approximately 24 hours after gemcitabine was based on the maximum tolerated dose and achievement of predefined LY2603618 plasma systemic exposures targets (area under the LY2603618 plasma concentration versus time curve from time zero to infinity \[AUC(0-inf)\] \>21,000 nanogram\*hour/milliliter \[ng\*h/mL\] and maximum LY2603618 plasma concentration \[Cmax\] \>2000 nanograms/milliliter \[ng/mL\]).

Overall survival (OS) time is defined as the time from the date of randomization to the date of death from any cause. For participants not known to have died as of the data cut-off date, OS time was censored at the last contact date the participant was known to be alive prior to the cut-off date. OS was summarized using Kaplan-Meier estimates.
