Biomarkers of Angiogenesis for Response to Therapeutic Combination in Advanced or Metastatic Kidney Cancer

Predictive Role of Circulating Biomarkers Involved in Angiogenesis in Metastatic Kidney Cancer in the Era of New Therapeutic Associations: Immunotherapies, Anti-angiogenic

This is a multicenter, exploratory, prospective study to identify angiogenesis and immune-related biomarkers predictive of progression free survival in patients with metastatic or advanced renal cell carcinoma treated by a combination of immunotherapy and antiangiogenic.

Recently, the management of renal cell carcinoma has undergone major changes with the emergence of combined therapies associating tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI) as first line treatments. However, there are no criteria to guide the choice between the different combinations validated and or between ICI combinations. Angiogenesis and immunity are intimately linked and some markers related have could be interesting to predict the efficacy of these combinations. Angiogenesis and immunity are highly related. This link may lead to new biomarkers to be explored to predict the response to TKI + ICI therapy combinations. On this basis, the investigators propose to conduct an open-label exploratory, multicenter prospective trial to study the association between angiogenesis and immune markers and the effect of combined TKI+ICI treatments.
