#2876 Efficacy of Surufatinib in Western Patients (pts) with Pancreatic Neuroendocrine Tumors (PanNETs)

Introduction: Surufatinib is a targeted inhibitor of tyrosine kinases VEGFR1, 2, & 3, FGFR1, and CSF-1R. The safety profile was favorable in 2 completed studies (NCT02133157, NCT02267967) conducted in China. A recent phase 3 placebo controlled study (NCT02588170) confirmed safety, and demonstrated superior efficacy (PFS: 9.2 v 3.8 months) of Surufatinib in Chinese pts with advanced extra-pancreatic NETs (epNET).

#2785 Inhibition of Cyclin Dependent Kinases Overcomes MYC-Driven Secondary Resistance to Everolimus in Digestive NETs

Introduction: Dysregulation of the mTOR pathway in digestive neuroendocrine tumours (d-NETs) led to the introduction of Everolimus (EVE) as treatment. EVE significantly increases PFS, but most patients acquire resistance, due to activation of feedback loops.

#2165 A Pilot Study of the Cyclin Dependent Kinases 4, 6 Inhibitor Ribociclib in Patients with Foregut Neuroendocrine Tumors

Introduction: Increased cyclin dependent kinases 4, 6 (cdk 4/6) activity is noted in the majority of well differentiated foregut neuroendocrine tumors (fNETs) due to mutations in MENIN and other aberrations. These tumors also have preserved Rb function making cdk 4/6 inhibitors attractive agents for therapy.

#2091 Differential Signalling Pathways Drive Therapeutic Resistance in Neuroendocrine Tumors

Introduction: Most of the current therapeutic strategies used for neuroendocrine tumors (NETs) are insufficient due to poor knowledge of these tumours. Despite showing differentiated features, NETs often exhibit therapeutic resistance to common treatments similarly to other cancers. Although signalling abnormalities have been reported, molecular mechanisms responsible for this resistance phenomenon are yet to be understood.

#1739 A Kinomic Approach to Identify Signaling Proteins Involved in Drug Resistance in GastroEnteroPancreatic Neuroendocrine Tumors

Introduction: Most of the current therapeutic strategies used for neuroendocrine tumors (NETs) result in tumour growth stabilization, eventually followed by tumour progression. Thus, despite their original characteristics, NETs exhibit similar resistance features to treatments than other more common tumours.
