#2826 NET-02: A Phase II Trial of Liposomal Irinotecan (nal-IRI) and 5-Fluorouracil (5-FU)/Folinic Acid or Docetaxel as Second-Line Therapy in Patients (pts) with Progressive Poorly Differentiated Extra-Pulmonary Neuroendocrine Carcinoma (PD-EP-NEC)

Introduction: The prognosis for pts with PD-EP-NEC is poor.

#2712 HORMONET: Study of Tamoxifen in Well Differentiated Neuroendocrine Tumors (NET) and Hormone Receptor Positive Expression

Introduction: We have shown immunohistochemistry (IHC) expression of estrogen (ER) and progesterone receptors (PR) in 20.8% and 18.8% of 96 NET patients (pts). An old clinical trial (Mortel C, 1984) suggested antitumor effects of estrogen/progesterone-directed therapies in NET. Yet the effects of an antiestrogen agent in NET pts whose tumor express ER and/or PR are unknown.

#2695 Different Treatment Options for Patients with Advanced Gastrointestinal Neuroendocrine Tumors

Introduction: Low sensitivity to chemotherapy leaves open question of optimal approach to drug therapy of neuroendocrine tumors (NETs). Somatostatin analogues (SSA) (octreotide, lanreotide) and mTOR inhibitors are successfully used in treatment.

#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.

#1797 An Open-Label Phase II Study to Evaluate the Efficacy and Safety Of PDR001 in Patients with Advanced Well-Differentiated Non-Functional NET of Pancreatic, Gastrointestinal (GI), or Thoracic Origin 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 (tx) options in various solid tumors. However, there is a paucity of data on checkpoint inhibitors in NET. In a phase I trial of PDR001 (mAb checkpoint inhibitor targeting PD-1) conducted in patients (pts) with multiple solid tumor types, a pt with histologically confirmed metastatic atypical pulmonary carcinoid demonstrated a RECIST-based tumor response and clinical benefit.
