Clinical Trials – Surufatinib for Neuroendocrine Cancer

Clinical Trials – Surufatinib for Neuroendocrine Cancer

Clinical Trials, Technical NETs
I first heard about this drug at ENETS Barcelona 2017 and then again in 2018.  It's now starting to be discussed in USA including at the 2019 ASCO conference. It was known then as Sulfatinib but for reasons unclear to me it was changed later to Surufatinib. It's a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity (TKI) associated with vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells.  Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies.  Surufatinib, manufactured by Hutchinson China MediTech Ltd (Chi-Med), is in proof-of-concept clinical trials in the USA and…

Clinical Trial: Lenvatinib Efficacy in Metastatic Neuroendocrine Tumors (TALENT)

Clinical Trials, Technical NETs
Lenvatinib has just completed a Phase 2 trial in Gastrointestinal (GI) and Pancreatic Neuroendocrine Tumours.  The trial was sponsored by Grupo Espanol de Tumores Neuroendocrinos (Spanish NET scientific organisation) and the manufacturers.  A European venture with sites in Austria, Italy, Spain, UK.   Headline: The responses are better than Everolimus (Afinitor) and Sunitinib (Sutent). What is Lenvatinib? It is a type of targeted therapy known as a multikinase inhibitor. The brand name is 'LENVIMA'. These work by inhibiting multiple intracellular and cell surface kinases, some of which are implicated in tumour growth and metastatic progression of cancer, thus decreasing tumour growth and replication. A range of receptor kinases are involved in these processes, including vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), stem cell factor (c-KIT), Flt3, fibroblast…
