| Measure | Time frame |
|---|---|
| Main Objective: Part 1: The primary objectives of the study are: -To investigate the safety and tolerability profile of the therapeutic vaccine hVEGF26-104/RFASE. -To determine the effective dose of hVEGF26-104/RFASE required to neutralize VEGF in serum, defined as a VEGF level below 9,0 pg/mL. Part 2: -To investigate the safety and VEGF neutralizing ability of hVEGF26-104/RFASE combined with irinotecan chemotherapy in a metastatic colorectal cancer expansion cohort. -To investigate the safety and VEGF neutralizing ability of hVEGF26-104/RFASE combined with the XELOX regimen (capecitabine plus oxaliplatin) in a metastatic colorectal cancer expansion cohort. ;Secondary Objective: The secondary objectives of the study are to investigate: -The anti-VEGF antibody titer, induced by hVEGF26-104/RFASE administration. -To determine the effective dose of hVEGF26-104/RFASE required to neutralize VEGF in plasma and in a platelet sample. -The effect of VEGF neutralization in a functional Ba/F3-R2 cell proliferation assay. The exploratory objectives of the study are: -To assess the cellular anti-tumor immune response upon hVEGF26-104/RFASE administration. -To assess immunomodulatory effects upon hVEGF26-104/RFASE administration. -To make a preliminary assessment of hVEGF26-104/RFASE to suppress angiogenesis within the tumor. -To assess the immune infiltration and the regulation of endothelial cell adhesion molecules in the tumor. ;Primary end point(s): Part 1: 1. Safety and tolerability of hVEGF26-104/RFASE. 2. Neutralization of endogenous VEGF in serum, defined as a VEGF level below 9,0 pg/mL as determined by sandwich ELISA. Part 2: 1. Safety and tolerability of hVEGF26-104/RFASE in combination with different chemotherapy regimens. 2. Neutralization of endogenous VEGF in serum, defined as a VEGF level below 9,0 pg/mL as determined by sandwich ELISA. ;Timepoint(s) of evaluation of this end point: 1. Safety and tolerability will be assessed at each treatment visit. The D | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Part 1: Secondary end points 1. Anti-VEGF antibody titer in serum, plasma and a platelet sample, as determined by indirect ELISA. 2. VEGF concentration in plasma as determined by sandwich ELISA. 3. VEGF concentration in a platelet sample as determined by sandwich ELISA. 4. Functional VEGF neutralization, as determined in a Ba/F3-R2-R2 cell proliferation bio-assay. Exploratory end points 1. Cellular (T-cell) immune response, as determined by ELISPOT 2. Immune modulation 3. Angiogenesis suppression within the tumor, by assessing microvessel density (MVD), quantity of proliferating endothelial cells and pericyt coverage. ;Timepoint(s) of evaluation of this end point: Secondary end points 1. Will be assessed at each treatment visit 2. Will be assessed at each treatment visit 3. Will be assessed at each treatment visit 4. Will be assessed at each treatment visit Exploratory end points 1. Will be assessed at day 0, week 4, week 10 and week 26 2. Will be assessed at day 0, week 10, week 10 and week 26 3. Will be assessed at day 0 and week 10 | — |
