Intervention(s):

Stage I: Three levels of dose Group A (Experimental): Dose of 200 µg of VSSP Group B (Experimental): Dose of 400 µg of VSSP Group C (Experimental): Dose of 600 µg of VSSP The VSSP product will be administered by subcutaneous route once a week for 3 weeks. According to the response of Myeloid-Derived Suppressor Cells (MDSC) on days 21 and 28, the patient will continue with a maintenance period with a biweekly or monthly administration frequency for 5 months. At this time evaluation of CD11b+/CD33 +/CD14-/CD66b +, 1 week before and another after month 5, will be made. Then, according to the response obtained, the patient will continue with the scheme he had, will change to a biweekly administration frequency in the same dose level or the higher dose or better selected dose will be offered until month 24. If the probability of satisfying the criterion of evidence of effect on day 21 is small in the 3 dose levels (200 μg, 400 μg, 600 μg), two new dose levels will be opened (1000 and 1200 μg). Stage II A level of dose according to selected dose of stage I.

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):

Serious adverse events with definite, very probable or probable causal relationship (Adverse events classified as “serious” and it has a causal relationship classified as “definite, very probable or probable”). Measurement time: in every evaluation visit and, in every product administration.

Key secondary outcomes:

Variables related to the effect: 1. Overall survival (Time from randomization until death from any cause). Measurement time: 12 and 24 months. 2. Objective response (According to Response Evaluation Criteria in Solid Tumors (RECIST version 1.1) it will classify in “Complete Response (CR), Partial Response (PR), Stable Disease (SD), Progression Disease (PD)). Measurement time: 4 weeks after last dose of second cycle and, 6, 9, 12 and 24 months. 3. Progression-Free Survival (Time from randomization until objective tumor progression or death). Measurement time: 24 months. 4. Response duration (Time from objective response (CR/PR) until objective tumor progression or death). Measurement time: 24 months 5. Evaluation of the percentage and absolute number in the population of peripheral blood mononuclear cells (PBMC). Measurement time: Day 0, 21, 28, 1 week before and 1 week after month 5, month 12, 18 and 24. 6. Percentage of lymphocytes in PBMC. Measurement time: 0, 21 and 28 days. Month 5, 12, 18 and 24. 7. Percentage of DC Myeloids and Plasmacytoids in PBMC. Measurement time: 0, 21 and 28 days. Month 5, 12, 18 and 24. 8. Percentage of regulatory T cells in the PBMC. Measurement time: 0, 21 and 28 days. Month 5, 12, 18 and 24. 9. Percentage of Monocytes in the PBMC. 0, 21 and 28 days. Month 5, 12, 18 and 24. 10. Arginase I, S100A8 / A9 and HMGB1 in the serum. Measurement time: 0, 21 and 28 days. Month 5, 12, 18 and 24. 11. Proliferation of T lymphocytes within PBMC. Measurement time: Day 0, 21, 28, 1 week after month 5, months 12, 18 and 24. 12. Quality of Life (EORTC QLQ-C30). Measurement time: At baseline and, 6, 12, 18 and, 24 months. Variables related to safety: 13. Adverse events-AE (Occurrence of AE (Yes, No); Description of AE (Name of the AE); Duration of the AE (Difference between the start and end date of the event); Intensity of the AE (Mild, Moderate, Severe, Life-threatening consequences, Death related to AE, according to the Common Criteria of Adverse Event Terminology (CTCAE) version 4.0); Causality relationship (Very probable, Probable, Possible, Improbable, Not related, Not evaluable); Seriousness of the AE (Serious, Not serious); Attitude towards treatment (No change, Modification of doses, Temporary interruption, Definitive interruption); Result of AE (Recovered, Improved, Persist, Squeals)). Measurement time: in each evaluation, in each administration of the product
