Trial Information

An Open Label, Phase 2 Study Evaluating the Safety and Efficacy of IMC-3G3 or IMC-1121B in Patients With Recurrent Glioblastoma Multiforme



- To assess the progression-free survival rate at 6 months after treatment with
ramucirumab or anti-PDGFR alpha monoclonal antibody IMC-3G3 in patients with recurrent
glioblastoma multiforme.


- To evaluate the acute and late toxicities associated with these regimens.

- To assess the objective tumor response rate.

- To estimate the overall survival of these patients.

- To describe the pharmacokinetic and pharmacodynamic profiles and immunogenicity of
these regimens.

OUTLINE: This is a multicenter study. Patients are sequentially assigned to 1 of 2 treatment

- Group 1: Patients receive ramucirumab IV over 1 hour on day 1. Courses repeat every 14
days in the absence of disease progression or unacceptable toxicity.

- Group 2: Patients receive anti-PDGFR alpha monoclonal antibody IMC-3G3 IV over 60-90
minutes on day 1. Courses repeat every 14 days in the absence of disease progression or
unacceptable toxicity.

Patients undergo blood sample collection periodically for pharmacokinetic, pharmacodynamic
biomarker (i.e., PDGFRα, PDGF, VEGF, VEGFR-1, and VEGFR-2), and immunogenicity analyses.

After completion of study treatment, patients are followed every 2 months.
