Patient case: 64-year-old male with bladder cancer; genetic feature: FGFR3 (S249C)

Clinical trial: Sorafenib in Combination With Irinotecan in Metastatic Colorectal Cancer Patients With KRAS Mutated Tumors

Summary: The aim of this multicenter randomized phase II trial is to determine the efficacy of sorafenib and irinotecan combination versus irinotecan monotherapy or versus sorafenib monotherapy in metastatic colorectal cancer patients with KRAS mutated tumors after failure of all active drugs known to be effective.

  -  Unidimensionally measurable on cross-sectional imaging
  -  In an area not previously irradiated
  -  Disease progression after failure of active drugs (5-Fu or 5-Fu prodrugs, irinotecan, oxaliplatin, bevacizumab)
  -  Patients with bone metastases are eligible if they have other measurable lesions
  -  WHO performance status ≤ 2
  -  Confirmation of KRAS mutation in codons 12 or 13 in the primary tumor or metastases
