A Retrospective Analysis of Safety and Efficacy of Everolimus in Gastroenteropancreatic Neuroendocrine Tumor (GEP-NET) Patients That Showed Progression after PRRT Abstract #712

Introduction: GEP-NET patients have been treated successfully with SSAs. Upon progression, peptide receptor radiotherapy (PRRT) with 177Lu-octreotate is successful. PRRT is not unlimited. Some patients became refractory after therapy. There is a high medical need. Everolimus (mTOR inhibitor) is a promising therapy for progressive G1/G2 GEP-NETs, with well-established safety. Everolimus has shown efficacy in patients with (non-)PNET (RADIANT-2/-3). However, toxicity data of Everolimus after PRRT is lacking.
Aim(s): Investigate whether the safety profile of Everolimus is different after failure of PRRT.
Materials and methods: Seven men and six women (median age: 54.5 years) that received Everolimus (5 or 10 mg) at least once directly after PRRT failure were included. Baseline: last documented characteristics prior initiation Everolimus. Patients were assessed for safety parameters at baseline, including previously reported adverse events during PRRT and laboratory values. Progression-free survival (PFS) was analyzed using a KM curve.

#2071 ElevatION:NET-201 A Phase II Study to Evaluate the Efficacy and Safety of PDR001 in Patients with Metastatic, Well-Differentiated NET of Pancreatic/GI/Thoracic Origin or Poorly-Differentiated GEP NEC Who Have Progressed on Prior Treatment
Introduction: Monoclonal antibody (mAb) inhibitors of immune checkpoints, including anti–PD-1 and anti–PD-L1, have become established treatment options in various solid tumors. However, there is a paucity of data on treatment effect of checkpoint inhibition in neuroendocrine tumors (NET) and neuroendocrine carcinoma (NEC). PDR001 is a high-affinity, humanized IgG4 mAb directed against PD-1 that blocks the binding of PD-L1 and PD-L2 to PD-1.
