Health condition(s) or Problem(s) studied:

Solid malignant tumors.

Intervention(s):

- Group I (CIGB-247V): antigen p64K-hVEGFKDR-(400 µg) + adjuvant NAcGM3/VSSP (200 µg) subcutaneously in the deltoid region. Scheme of 9 immunizations: 1 time / week (1st 8 weeks) + a booster at week 12. - Group II (CIGB-247V): antigen p64K-hVEGFKDR-(400 µg) + adjuvant NAcGM3/VSSP (400 µg) subcutaneously in the deltoid region. Scheme of 9 immunizations: 1 time / week (1st 8 weeks) + a booster at week 12. - Group III (CIGB-247V): antigen p64K-hVEGFKDR-(800 µg) + adjuvant NAcGM3/VSSP (200 µg) subcutaneously in the deltoid region. Scheme of 9 immunizations: 1 time / week (1st 8 weeks) + a booster at week 12. - Group IV (CIGB-247A): antigen p64K-hVEGFKDR-(200 µg) + aluminum phosphate adjuvant (0.7 mg AL3+) subcutaneously in the deltoid region. Scheme of 5 immunizations: 1 once every 14 days (1st 8 weeks) + booster at week 12. - Group V (IGBC-247A): antigen p64K-hVEGFKDR-(400 µg) + aluminum phosphate adjuvant (0.7 mg AL3+) subcutaneously in the deltoid region.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Clinical Adverse Events (AE). Measuring time: in each immunization and at weeks 12,13 and 16. -Apearence of EA (Yes, No) -Description of EA (name of the event) -Intensity of EA (mild, moderate, severe). Laboratory tests (numerical values of hematology, biochemistry and urine). Measuring time: at weeks 1, 5, 9, 13 and 16.

Key secondary outcomes:

Immune response(determination of serum titers of anti-VEGF; percent of inhibition - binding VEGF and its receptor; ELISPOT for interferon gamma: average number of points). Measuring time: in weeks 1, 5, 9, 13 and 16. Quality of life (questionnaire EORTC QLQ-C30: worse, unchanged, slightly improved, moderately improved, much improved). Measuring time: in weeks 16. Tumor Response Assessment (tumor diameter). Measuring time: at week 16.
