Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: IMC-1121B<br>Active-control participants (first 16 participants) will receive one dose of moxifloxacin orally 7 days before the first treatment with ramucirumab. All participants will undergo triplicate electrocardiogram (ECG) tests (consisting of three individual ECGs performed consecutively within a period of 4 minutes) and vital signs at various times over the trial period. For Cycle 1, all participants will also receive 2 infusions of diphenhydramine before ramucirumab therapy (the first infusion is 1 day before therapy and the second infusion is 15 minutes before therapy). For Cycles 2, 3, and 4, all participants will receive diphenhydramine 15 minutes before ramucirumab therapy. For Cycle 5 and beyond, diphenhydramine infusions before ramucirumab therapy are at the investigator's discretion. Ramucirumab [10 milligrams per kilogram (mg/kg)] intravenously over 60 minutes, once every 3 weeks for minimum of 9 weeks without a break in between. | Biological: IMC-1121B<br>* IMC-1121B (Ramucirumab) 10 mg/kg intravenously (IV) over 60 minutes, once every 3 weeks for minimum of 9 weeks.<br>* Other names: LY3009806;Drug: Moxifloxacin<br>* Administered orally<br>Drug: Diphenhydramine<br>* Administered IV<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline to Cycle 3 in QT/Corrected QT (QTc) Interval Prolongation in Participants | All electrocardiogram (ECG) tests were performed in triplicate prior to ramucirumab treatment. QT is the interval between the Q and T waves and QTc is the QT corrected for heart rate using Fridericia's formula: QTc = QT/RR^0.33 where RR is the interval between 2 R waves. Each participant's mean QT/QTc value was calculated for each ECG test during Cycle 3 and compared to his/her mean pretreatment QT/QTc value. The greatest change from baseline during Cycle 3 was reported. QTc prolongation is defined as a QTc exceeding 10 milliseconds (msec) with a lower 90% confidence interval (CI) exceeding 5 msec at any postdose time points per the International Conference on Harmonization (ICH) E14 guidelines for non-thorough QT studies (ICH 2005; ICH 2008). Least squares (LS) mean was calculated using a linear mixed model for repeated measures (MMRM) and adjusted for serum concentration. | Baseline, Cycle 3 (1 cycle=21 days) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Drug-Related Adverse Events (AEs) | Data presented are the number of participants who experienced treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), Grade 3 or higher TEAEs, or adverse events (AEs) leading to discontinuation of treatment that were considered to be related to ramucirumab. A summary of SAEs and other non-serious AEs, regardless of causality, is located in the Reported Adverse Events section. | Baseline up to data cut off (approximately 105.6 weeks) |

| Area Under Concentration (AUC) During Cycle 1, Day 4 | AUC was summarized once per cycle because participants only received 1 dose of IMC-1121B (ramucirumab) per cycle. Refer to secondary outcome measure 9 for AUC during Cycle 1 (Day 1 through Day 15). | Approximately Week 1 (Cycle 1, Day 4) | 
| Area Under Concentration (AUC) During Cycle 1, Day 8 | AUC was summarized once per cycle because participants only received 1 dose of IMC-1121B (ramucirumab) per cycle. Refer to secondary outcome measure 9 for AUC during Cycle 1 (Day 1 through Day 15). | Approximately Week 2 (Cycle 1, Day 8) |
