#4607 BH3-mimetic drugs elicit cell death of neuroendocrine tumours in preclinical models – An emerging therapeutic strategy for NETs

Introduction: There is an unmet clinical need to identify new, effective therapies for patients with neuroendocrine tumours (NETs). Analysis of single-cell expression data revealed that NETs express high levels of the Bcl2 family of antiapoptotic proteins. Therefore, we hypothesised that proapoptotic drugs, such as BH3-mimetics, can induce programmed cell death, i.e., apoptosis, of neuroendocrine cancer cells.

#4564 Vasculogenic mimicry in neuroendocrine tumour across different primary sites

Introduction: Anti-angiogenesis treatments targeting VEGFRs, including Surufatinib and Cabozantinib, etc. showed better efficacy for pancreatic neuroendocrine tumours (NET) than NET of other primary sites. Recent clinical trial targeting tumour necrosis factor receptor-associated protein-1, leading to inhibition of vasculogenic mimicry (VM) showed contrary results to current VEGFRs-targeted treatments. However, VM of NET across different primary sites are yet to be understood.

#4518 Efficacy and safety of cabozantinib (CABO) for advanced Grade 3 (G3) neuroendocrine tumours (NETs) after progression on prior therapy: Subgroup analysis of the phase III CABINET trial (Alliance A021602)

Introduction: Well-differentiated G3 NETs have been described as a distinct category recently, and randomised data regarding efficacy of therapy are scarce. In the phase 3 CABINET trial (NCT03375320), CABO significantly prolonged progression-free survival (PFS) compared with placebo (PB) in patients (pts) with advanced, previously treated, progressive well-differentiated extra-pancreatic NETs (epNETs) and pancreatic NETs (pNETs) of all grades (Chan et al., NEJM, 2024).

#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.

#4146 Anticancer activity of Cabozantinib and Temozolomide in cell lines derived from lung carcinoid and pancreatic neuroendocrine tumors

Introduction: Limited therapeutic options are available for patients with advanced neuroendocrine neoplasms (NENs). Cabozantinib (CBZ), a tyrosine kinase inhibitor including c-MET pathway, and Temozolomide (TMZ), an alkylating agent enhancing the anti-angiogenic effect of CBZ, are emerging as promising treatments in NENs.
