简要总结
Evaluating the impact of OCTREOTIDE LAR on the immune response by studying Regulatory T-cell (T-Reg) and Myeloid-derived suppressor cells (MDSC) and the immunoregulatory cell population in peripheral blood of NET G1 / G2 patients treated with Octreotide LAR
详细描述
MDSCs and T-Regs will be evaluated at baseline pre-treatment with octreotide, after 15 days, at three and at six months and before each octreotide LAR administration for 12 months. MDSC cells will be detected by surface receptors LIN-, CD11b, CD14, CD15, CD33, CD124-IL4-Ra, CD184-CXCR4, CD279-PD1, HLA-DR and T-reg cells from CD3, CD4, CD8 receptors , CD25, CD39, CD45RA, CD45R0, CD62L, CD127, CD152-CTLA-4, CD184-CXCR4, CD278-ICOS, CD279-PD-1. Briefly, CD4 + cells will be separated by negative selection, using the mixture of human CD4 antibodies. Octreotide is currently a registered drug to the FDA, EMA and AIFA with the indication for the treatment of well and moderately differentiated NETs functioning and not working on the front line. .

研究组 & 干预措施
OCTREOTIDE LONG-ACTING RELEASE (OCT LAR)
OCT LAR is already registered By FDA for USA, by EMA for Europe and , also, by AIFA for Italy.
干预措施: Octreotide Acetate (Drug)
结局指标
主要结局
Exploring the changes in immune-regulatory cells induced by OCT LAR
时间窗: 6 months
The primary objective of the project is to evaluate changes in immune-regulatory cells induced by OCT LAR from baseline to month 6. Therefore, we will observe the impact of OCTREOTIDE LAR on the immune response by studying T-Reg and MDSC and the immunoregulatory cell population in peripheral blood of patients with neuroendocrine tumors G1 / G2 treated with OCT LAR.
次要结局
- Outcome(3 months (PFS - ORR))
- safety assessment(1 month (safety))
