Background Vascular endothelial growth factor receptor-2 (VEGFR-2) and its ligands ( VEGF-A, -C, and -D ) are important mediators of angiogenesis In human breast cancer, intensive neovascularization and tumor angiogenesis correlate with metastases and poor prognosis Clinical trials of antiangiogenic therapy for breast cancer have not yet demonstrated improvements in overall survival
Mechanism of ramucirumab action • Ramucirumab (IMC-1121B; RAM) a recombinant human IgG1 monoclonal antibody that binds the extracellular domain of VEGF Receptor-2 VEGF-A VEGF-A VEGF-CVEGF-D VEGF-CVEGF-D Ramucirumab VEGF binds toVEGFR2 receptor;VEGF-C, -D competefor binding toVEGFR2 Ramucirumabbinds to VEGFR2, blocks VEGFligand binding VEGFR2 VEGFR2 Endothelial cell Ligand binding activates VEGFR2 andp44/p42 MAP kinases No signaling Angiogenesis Tumor growth Inhibit new blood vesselformation and tumor growth

Study Endpoints and Analyses • Primary Endpoint • Investigator-Assessed Progression-free Survival (PFS) • 796 eventsfrom 1113 patients; 86% power to detect a difference of 2 mos in median PFS (6 mos in the control group vs. 8 mos), HR=0.75 • Primary analysis is a stratified log-rank test with 2-sided α=0.05 • Survival Interim Analysis • To occur at time of final PFS analysis or 375 deaths, whichever is later. • Secondary Endpoints • Overall Survival (OS) • 792 events; 85% power to detect a difference of 6 mosin median survival (24 mosfor the control group vs 30 mos), HR=0.8 • TTP, ORR, safety and QOL
Key Eligibility Criteria • Women with HER2-negative metastatic or locally-recurrent and inoperable breast cancer • No prior chemotherapy or biologic therapy for metastatic / recurrent breast cancer • Completed (neo) adjuvant taxane therapy ≥ 6mos, (neo) adjuvant biologic therapy ≥ 6wks, and radiotherapy with curative intent ≥ 3 wks prior to randomization • Adequate hematologic, hepatic, and renal function • ECOG Performance Status of 0-1 • No uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, or symptomatic or poorly controlled cardiac arrhythmia

Best Overall Response and Time to Progression Investigator Review Assessment *Log-rank p-value stratified by prior use of taxane therapy, visceral metastasis, hormone receptor status, and geographic region.
Treatment Administration * Cycle consists of 21 days
Treatment Emergent Adverse Events(≥10% of patientsand higher incidence on RAM + Docetaxel Arm) • MedDRA Version 16.0; CTCAE version 3.0 are used. • *p-value <0.05 using Fisher’s exact test comparing RAM to PBO • † Consolidated AE category comprising synonymous MEdDRA preferred terms.
Most Common Hematologic AEs • MedDRA Version 16.0; CTCAE version 3.0 are used. • *p-value <0.05 using Fisher’s exact test comparing RAM to PBO • † Consolidated AE category comprising synonymous MEdDRA preferred terms.
Adverse Events of Special Interest • MedDRA Version 16.0; CTCAE version 3.0 are used. • *p-value <0.05 using Fisher’s exact test comparing RAM to PBO
Treatment Emergent Adverse Events with an Outcome of Death(Any TEAE with a fatal outcome in 2 or more patients on either treatment arm) • *Terms listed under Consolidated AE Category are composite terms comprising synonymous MedDRA preferred terms. • † Includes Disease and Neoplasm progression reported as adverse events
Conclusions • Ramucirumab + docetaxel did not significantly prolong the primary endpoint of investigator assessed Progression Free Survival over placebo + docetaxel (HR 0.88, p=0.077) • IRC assessed PFS was slightly longer on the RAM arm (HR 0.79, p=0.008) • No difference observed in this interim overall survival analysis • ORR, DCR, and TTP were higher on the Ramucirumab arm • Efficacy results did not differ in clinical subgroups • Ramucirumab + docetaxel therapy had higher rates of adverse events including fatigue, hypertension, bleeding, febrile neutropenia, and stomatitis
