Study summary

The study is studying the joint contribution and interactions of germline variants and somatic mutations and their impact on Renal Cell Carcinoma (RCC) development and treatment (immunotherapy).

Read the detailed description

One hundred newly diagnosticated stage IV RCC patients will be recruited in the Ribeirao Preto Medical School.

Patients will be treated with immune checkpoint inhibitors (ICI) combination: nivolumab (3 mg/kg of body weight) plus ipilimumab (1 mg/kg) intravenously every three weeks for four doses, followed by nivolumab 480mg every four weeks, until progression, toxicity or complete two years of treatment.

Patients will be followed up for the clinical outcome (progression-free survival, best response, and overall survival).

Fresh-frozen primary tumor tissue will be collected for somatic genomic characterization.

Blood DNA will be genotyped for the identification of common germline variation, as well as ancestry determination.

    Nivolumab IV 3mg/kg 3/3w + Ipilimumab 1mg/kg 3/3w 4 doses, followed by Nivolumab IV 480mg 4/4w until progression, toxicity, or up to 2 years of use.

    Drug: Nivolumab · Drug: Ipilimumab

Interventions

  • DrugNivolumab

    Nivolumab is called an anti-PD-1 (Programmed Cell Death Ligand 1) or a checkpoint inhibitor and is an antibody (a type of human protein) designed to allow the body's own immune system to destroy tumors

    Also known as: Opdivo

  • DrugIpilimumab

    Ipilimumab is called an anti-CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) and is a type of antibody that works to prevent the body's immune system from stopping to fight a specific cancer

    Also known as: Yervoy
