#2682 PAK4-NAMPT Dual Inhibition as a Novel Strategy for Therapy Resistant Pancreatic Neuroendocrine Tumors

Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

#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.

#1555 Antitumor Activity of Desmopressin (dDAVP) and the New Analog [V4Q5]dDAVP in Human Small Cell Lung Cancer

Introduction: Lung cancer is the main cause of cancer death. Non small cell lung cancer (NSCLC) cause about 85% of cases and small cell lung cancer (SCLC) represents 15%. Therapy resistance is commonly related with a transformation from adenocarcinoma to SCLC. SCLC shows neuroendocrine (NE) features and exhibits aggressive behavior. In vitro production of vasopressin (AVP) was reported in SCLC. The AVP V1 receptors are associated with mitogenic signaling pathways, while AVP V2 receptor (V2r) is related with an opposite effect. DDAVP is a synthetic analog of AVP that acts as a selective agonist for V2r. DDAVP displays cytostatic and antimetastatic properties in breast and colorectal cancer. In our laboratory a new analog, [V4Q5]dDAVP, showed improved cytostatic activity
