#4389 The LOLA trial: Phase II trial with combination of cabozantinib plus lanreotide in gastroenteropancreatic (GEP) and thoracic neuroendocrine tumours (NETs) – Interim results of step 1

Introduction: LOLA is an Italian, multicentre, open-label, double cohort, non-randomised, 3-stage, phase 2 trial aiming to assess the safety and activity of the combination of cabozantinib (CABO) + lanreotide (LAN) in patients (pts) with advanced or metastatic GEP and unknown primary NETs with Ki-67 > 10% or thoracic NET. In NETs sunitinib is the only TKI approved in advanced pancreatic NETs. While CABO has been reported superior to sunitinib in renal cancer its role in NETs is still investigational.

#4364 Single agent axitinib in the management of patients with progressive pheochromocytoma and paraganglioma

Introduction: Radiolabelled therapy with meta-iodobenzguanine (MIBG) and chemotherapy with a combination of cyclophosphamide, vincristine, and dacarbazine can help manage patients with metastatic pheochromocytoma and paraganglioma (mPPGL). The phase II FIRSTMAPPP study supports the use of the tyrosine kinase inhibitor sunitinib in these malignancies, with median progression-free survival values of 8.9 versus 3.6 months and overall response rates of 31% versus 8% for sunitinib versus placebo. The median duration of sunitinib therapy was 11 months. Concurrent with this study, we launched a single-arm trial to examine the activity of a similar tyrosine kinase inhibitor, axitinib.

#4345 Real-life results of the treatment with lutetium in advanced neuroendocrine tumours

Introduction: Therapy using lutetium-177 dotatate (177LU) was approved in Europe in 2017 for the treatment of advanced neuroendocrine tumours (NETs). Since then, it has become part of the strategies for treating NETs, making it now possible to evaluate real-life results.

#4029 An Italian multicenter phase II trial of Metronomic Temozolomide in unfit patients with advanced neuroendocrine neoplasms: MeTe study

Introduction: Metronomic schedule of temozolomide (mTEM) can overcome resistance induced by O6-methylguanine-DNA-methyltransferase (MGMT) and reduce toxicities being particularly suitable for unfit patients (pts). We present the first data from a non-planned interim analysis of this phase II Italian single arm multicenter study.

#4015 Responses to Cabozantinib plus Atezolizumab in a wide population of advanced and progressive neuroendocrine neoplasms (NENs): A prospective multi-cohort basket phase II Trial (CABATEN / GETNE-T1914)

Introduction: Angiogenesis plays a key role in development and progression of NENs and synergism has been observed when combined with immune-checkpoint inhibitors in other tumors.
