- Primary Outcome Measures
Name Time Method <p>- Safety and tolerability of hVEGF26-104/RFASE, measured by the number of<br /><br>participants with serious and non-serious adverse events<br /><br>- Neutralization of endogenous VEGF in serum, defined as a VEGF level below 9.0<br /><br>pg/mL as determined by sandwich ELISA. </p><br>
- Secondary Outcome Measures
Name Time Method <p>- Anti-VEGF antibody titer in serum, plasma and a platelet sample, as<br /><br>determined by indirect ELISA.<br /><br>- VEGF concentration in plasma as determined by sandwich ELISA.<br /><br>- VEGF concentration in a platelet sample as determined by sandwich ELISA.<br /><br>- Functional VEGF neutralization, as determined in a Ba/F3-R2-R2 cell<br /><br>proliferation bio-assay.<br /><br>- Cellular (T-cell) immune response, as determined by ELISPOT<br /><br>- Immune modulation<br /><br>- Angiogenesis suppression: Within the tumor, by assessing microvessel density<br /><br>(MVD), quantity of proliferating endothelial cells and pericyt coverage. </p><br>
