Full efficacy and safety data are expected to be presented at the European Society for Medical Oncology (ESMO) 2016 Congress in Copenhagen, Denmark.

Sunitinib is an oral multi-kinase inhibitor that was initially granted approval by the U.S. Food and Drug Administration for the treatment of patients with advanced RCC. It is also indicated for imatinib-resistant or intolerant gastrointestinal stromal tumors, as well as advanced pancreatic neuroendocrine tumors.
