Biomarker Study of Pts With Metastatic ccRCC Undergoing Sequential Therapy With 1st Line Sunitinib and 2nd Line Axitinib

Instituto do Cancer do Estado de São Paulo7 enrolled

Overview

This is a prospective single arm phase II study to evaluate potential prognostic and/or predictive biomarkers in patients with metastatic ccRCC undergoing treatment with 1st line sunitinib on a 4/2 schedule followed by axitinib on 2nd line therapy.

In this study, all included patients will receive sunitinib until disease progression and/or limiting toxicity. If patients develop toxicities ≥ Grade 2 on 50 mg per day 4 weeks-on / 2 weeks-off schedule, a modified schedule of 50 mg/day 2 weeks-on / 1 week-off will be offered. After disease progression on sunitinib, all eligible patients will receive axitinib 5 mg twice a day. The investigators plan to assess, by next generation sequencing, the prevalence of mutations in several cancer related genes in baseline archived tissue from the patients included in the study, and the potential correlations between these somatic mutations and anti-VEGF (Vascular Endothelial Growth Factor) therapy efficacy.
