简要总结
Single arm Phase I/II multicentric open labeled, with translational sub-study, of avelumab plus autologous dendritic cell vaccine in pre-treated mismatch repair-proficient (MSS) metastatic colorectal cancer patients..
详细描述
This 2-phases study will first evaluate two different doses/schema of avelumab plus autologous dendritic cell vaccine (ADC) vaccines, in intention to define which dose is effective without hampering safety. Second phase will consist in an standard analysis of efficacy and progression free survival. It is expected that 4 Spanish Sites will include patients in phase I and 8 Spanish Centers will include patients in the phase II of the study

- •History of other tumors in the past 5 years.
- •Active infections.
- •Current immunosuppressive treatment, except for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)."
- •Known hypersensitivity to avelumab, ADC vaccines or their components.
- •Legal incapacity or limited legal capacity.
