Injections, Subcutaneous
|
Receptor, Epidermal Growth Factor
|
Group HER1/VSSP. Dose level 400 µg (experimental): The vaccine will be administered by subcutaneous route, the first 5 doses every 15 days (induction stage) and then the remaining 10 doses every 28 days until one year of treatment (maintenance stage).
Group HER1/VSSP. Dose level 800 µg (experimental): The vaccine will be administered by subcutaneous route, the first 5 doses every 15 days (induction stage) and then the remaining 10 doses every 28 days until one year of treatment (maintenance stage).
In each dose level will be recruited up to a maximum of 20 patients per 3 location (20 patients per dose level) for a maximum of 120 patients.

Primary Outcome(s)
|
Proportion of patients with serious adverse events with causal relationship (EAS with definite / highly probable or probable causality with HER1 vaccine). Time of measurement: 0, 14, 28, 42, 56, 84 112, 140, 168, 196, 224, 252, 280, 308, 336, and 364 days
|
Secondary Outcome(s)
|
Related to Immunogenicity: 1. Antibody response IgG against DEC-HER1 protein (Antibody titers by ELISA technique). Measurement time: Day 0, 56, 84, 112, 168, 196, 252 and 336. 2. Recognition of the A431 human vulvar tumor line by means of the FACS flow cytometer. Measurement time: Day 0, 56, 84, 112, 168, 196, 252 and 336. 3. Response of T cells producing IFN? by means of an ELISPOT technique. Measurement time: Day 0, 112, and 196. Related to security: 1. Adverse Events-AE (Intensity using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The CTCAE establishes the categories: Grade 1 Mild, Grade 2 Moderate, Grade 3, Grade 4 Life-threatening, Grade 5 Death related to EA; Causal relationship will be classified according to 45/2007 CECMED regulation and WHO categories. The categories are: Definitive, Very likely/safe, Probable, Possible, Unrelated and Unknown). Measurement time: Day 0, 14, 28, 42, 56, 84 112, 140, 168, 196, 224, 252, 280, 308, 336, and 364. 2. Results of laboratory tests (Hematologic: Hemoglobin (g/dL), Hematocrit (quantity x109/L), Quantity of total leukocytes (quantity x109/L), Neutrophil (%), Lymphocytes (%), Basophils (%), Eosinophils (%), Monocytes (%). Biochemistry: Creatinine (mmol/L), Alkaline Phosphatase (U/L), TGO (U/L), TGP (U/L), Glycemia (mmol/L), LDH, PSA (mmol/L). Urine: Hematuria (x104), Leucos (x104), Proteinuria (x104)). Measurement time: at baseline and every four weeks during the study. Only PSA will be given to patients with hormone-castration-resistant prostate cancer at months 3, 6, 9, and 12. 3. Vital signs (blood pressure (values in mmHg), heart rate (values in beats per minute), and temperature (values in degrees Celsius). Measurement time: at baseline and, every time in the immunization, days 0, 14, 28, 42, 56, 84, 112, 168, 196, 252 and 336. 4. Batch of HER1 (number of the batch used). Measurement time: in every immunization. Related to effect 1. Objective response (Complete Response, Partial Response, Stable Disease according to RECIST criteria). Measurement time: 3, 6 and 9 months; and 4 weeks after the last immunization. 2. Progression-free survival (Time from randomization patient until the progression or the death). Measurement time: day: 0, 14, 28, 42, 56, 84 112, 140, 168, 196, 224, 252, 280, 308, 336, and 364. 3. Overall Survival (Time from randomization patient until the death). Measurement time: 24 months.
