Real-word evidence in anti-VEGF naive patients treated with pazopanib for metastatic renal cell carcinoma (mRCC), the APOLON Study

Background: Immune checkpoint inhibitor-based combinations have become the standard of care for treatment-naive metastatic renal cell carcinoma (mRCC). Tyrosine kinase inhibitor (TKI) monotherapy, however, may remain an option particularly for patients with a favourable International Metastatic Database Consortium (IMDC) risk. Material and methods: APOLON is a non-interventional, multicentric prospective study with mRCC patients receiving frontline pazopanib treatment, designed to assess progression-free survival (PFS), overall survival (OS), objective response rate, tolerability, and subsequent post-pazopanib therapy sequences. Result: The 217 patients were 71.0% male, with a median age of 69.6 years, an Eastern Cooperative Oncology Group performance status ≥2 in 17.6%, and mRCC with a favourable (27.1%), intermediate (52.1%) or poor (20.8%) IMDC score. Metastases were mainly located in lung (64.1%), bone (28.6%), mediastinal (18%)/abdominal (17.1%) lymph nodes. Median PFS was 10.6 months [95% confidence interval (CI) 9-12.5 months], similarly in patients aged
