What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs)	DLT is defined as 1 of the following adverse events(AE) reported during the Phase 1a DLT observation period,if considered to be definitely,probably,or possibly related to either study regimen by the investigator;and fulfills any 1 of the following criterion using(NCI)CTCAE version(v)4.03:Grade4 immune-related AE,Grade4 non-laboratory AE,any CTCAE Grade ≥3 QT prolongation AE,≥Grade3 colitis or noninfectious pneumonitis irrespective of duration,Grade3 immune-related AE(excluding colitis,QT prolongation,or pneumonitis) that does not downgrade to Grade2 within 3 days after onset of event despite optimal medical management including systemic corticosteroids,or does not downgrade to ≤Grade 1 or baseline within 14 days,Grade2 pneumonitis that does not resolve to ≤Grade 1 within 3 days of the initiation of maximal supportive care,including corticosteroid therapy,Grade3 toxicity lasting an extended time despite optimal supportive care and there were also laboratory abnormalities criterion.	Cycle 1 (28 Days)
Maximum Tolerated Dose (MTD) of LY2510924	MTD was determined after the evaluation of Phase 1a portion of the trial. For Phase 1a, any DLT-equivalent toxicities observed in Cycle 2 and beyond were also be considered in dose escalation and determining MTD/recommended Phase 2 dose. See outcome measure number 1 for the DLT criterion.	Cycle 1 (28 Days)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics: Area Under the Concentration-Time Curve (AUC [0-∞]) of LY2510924 When Co-Administered With Durvalumab	Pharmacokinetics: Area Under the Concentration-Time Curve (AUC [0-∞]) of LY2510924 when Co-Administered with Durvalumab	Cycle 1 Day 1: Predose, 0.5, 2, 4, 6, 8, 24-30 hours; Day 15: Predose, 0.5, 2, 4, 6, 8 hours
Number of Participants With Anti-Durvalumab Antibodies When Administered in Combination With LY2510924	Number of participants with treatment-emergent positive Anti-Durvalumab antibodies was summarized by treatment group.	Predose Cycle 1 Day 1 through 90 Day Post Treatment Follow Up (Up To 12 Months)
Percentage of Participants With Best Overall Response of Complete Response (CR) or Partial Response (PR) [Objective Response Rate (ORR)]	Best overall response of CR or PR was defined using RECIST v 1.1 criteria. CR was defined as the disappearance of all lesions, pathological lymph node reduction in short axis to <10 mm, and normalization of tumor marker levels of non-target lesions. PR was defined as ≥30% decrease in sum of diameter(SOD) of target lesions taking as reference the baseline sum diameter. PD was defined as ≥20% increase in SOD of target lesions and short axes of target lymph nodes, taking as reference the smallest sum of the longest diameters recorded since treatment started and an absolute increase in sum diameter of ≥5 mm; appearance of ≥1 new lesions and/or unequivocal progression of existing non-target lesions. Participants who had no post baseline tumor assessments were considered non-responders and included in the denominator when calculating response rate. Percentage of participants=(number of participants with CR+PR/total number of participants)*100.	Baseline through Measured Progressive Disease or Death (Up To 12 Months)
Percentage of Participants With CR, PR, or Stable Disease (SD) (Disease Control Rate [DCR])	DCR: percentage of participants with CR, PR, or SD using RECIST v 1.1 criteria. CR: disappearance of all lesions, pathological lymph node reduction in short axis to <10 mm, and normalization of tumor marker levels of non-target lesions. PR: ≥30% decrease in sum of diameter (SOD) of target lesions taking as reference baseline sum diameter. PD: ≥20% increase in SOD of target lesions and short axes of target lymph nodes, taking as reference smallest sum of longest diameters recorded since treatment started and an absolute increase in sum diameter ≥5 mm; appearance of ≥1 new lesions and/or unequivocal progression of existing non-target lesions. SD: neither sufficient shrinkage to qualify for PR nor increase to qualify for PD. Participants who had no post baseline tumor assessments were considered non-responders and included in the denominator when calculating response rate. Percentage of participants=(number of participants with CR+PR+SD/total number of participants)*100.	Baseline through Measured Progressive Disease (Up To 12 Months)
