#2075 Phase 1 Pharmacokinetic and Pharmacodynamic Study of APOC, a New Controlled Release Formulation (CRF) of 15mg Octreotide Acetate in Healthy Male Volunteers
Introduction: Somatostatin analogues (SSAs) are considered the gold standard for systemic therapy of advanced neuroendocrine tumors (NETs). Octreotide is one of the SSAs most widely used in long-term therapies of NETs. There is increasing evidence that clinical benefits could be obtained with higher SSAs circulating levels but remain unreachable with current products without impacting significantly the quality of life of the patients. APOC is a new injectable controlled release technology containing Octreotide invented and developed by Ascil-Biopharm and designed to cover specifically these clinical unmet needs. It is presented as ready-to-use and can easily be manufactured at selected doses and durations in prefilled syringe.

#2087 Prospective, Multi-Center, Open Label, Phase Study II of APOC, a New Controlled Release 15mg Octreotide Acetate, for the Treatment of Advanced NETs
Introduction: Somatostatin analogues (SSAs) are the cornerstone of systemic therapy of advanced NETs. The efficacy controlling hormone release and tumor growth together with the favorable toxicity profile have positioned SSAs as upfront therapy. Despite of second-line therapies including targeted agents, chemotherapy and radiolabeled peptides have demonstrated activity controlling tumor growth, the less favorable toxicity profiles become a usual discussion with patients (pts) to preserve the quality of life (QoL). Additionally, from concordant flow of evidences clinical benefits could be obtained with higher SSAs circulating levels but remain unreachable with current products. APOC is a new controlled release ready-to-use convenient therapeutic, designed to cover specifically these clinical unmet needs.

#151 Rationale for combining mTOR with other targeted agents in the treatment of neuroendocrine tumors
Introduction: Advanced neuroendocrine tumors (NETs) are aggressive and incurable with standard treatment. Many cellular targets are being evaluated in this patient population, including mammalian target of rapamycin (mTOR), a kinase that is the central regulator of several signaling pathways related to cell growth, angiogenesis, and bioenergetics. Because mTOR serves as a neoplastic switch activated by many cancer-related mutations, mTOR inhibition may have broad efficacy across tumor types, including NETs. Somatostatin analogs (SSAs) have long been used to treat carcinoid symptoms in NET patients. The SSA octreotide long-acting release (LAR) demonstrated significant antitumor effects against advanced midgut NETs in the phase III PROMID study.

#2058 On-going Evaluation of the Use of Resources and the Costs (UR/C) Associated with Controlled or Uncontrolled Carcinoid Syndrome (CS) in Patients (pts) with Neuroendocrine Tumours (NETs): RECOSY Study Design
Introduction: NET pts have high rates of mortality and morbidity, as wells as decreased health-related quality of life (HRQoL) due to CS. Though there is little research on the economic impact of CS, recent studies show that some symptoms, i.e. diarrhoea, are associated with higher healthcare expenditure and use of resources.

#2081 Preclinical Testing of SSA Compounds in a Model of Pancreatic Neuroendocrine Tumors to Optimize Scheduling and Drug Exposition
Introduction: Somatostatin analogues (SSA) such as Octreotide and Lanreotide have demonstrated a significant benefit in Neuroendocrine Tumors, particularly in the well/moderately differentiated types. Nevertheless, there are still several aspects of SSA treatments that remain unsolved, such as drug exposition in patients and schedule optimization.

#334 Everolimus + Octreotide LAR v. Placebo + Octreotide LAR in Patients With Advanced NET: Results of a Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase 3 Trial (RADIANT-2)
Introduction: Everolimus, an oral inhibitor of mTOR, demonstrated promising antitumor activity in patients with NET as a single agent and in combination with octreotide LAR in two phase 2 studies.

#18 Long-acting release octreotide induce complete response in type 1 gastric carcinoid tumors
Introduction: Gastric endocrine tumors (GET) are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, GET may also be aggressive when sporadic and may sometimes mimic the course of gastric adenocarcinoma. Current incidence of GETs is estimated at around 8% of digestive endocrine tumors. Yearly age-adjusted incidence is around 0.2 per population of 100,000. Gastric carcinoids (ECLomas) develop from gastric enterochromaffin-like cells (ECL cells) in response to chronically elevated gastrin. Type 1 tumors (ECLomas in the course of atrophic gastritis) may occur in conditions of achlorhydria secondary to auto-immune atrophic fundic gastritis. It occurs mostly in women and they are non-functioning tumors, typically found during upper GI endoscopy performed for dyspepsia. ECLomas present frequently as multiple polyps, usually < 1 cm in diameter in the gastric fundus. Type 1 tumors are almost exclusively benign lesions with little risk of deep invasion of the gastric parietal wall. The neoplastic ECL cells become progressively dedifferentiated with an increasing number of Ki-67 immunoreactive (IR) cell nuclei. In addition, there is a substantial decrease in argynophil and IR NE cells that can be visualized by conventional methods. ECLomas secondary to hypergastrinemia should be closely followed for signs of clinical and histopathological tumor progression. Such ECLomas deserve early, active, radical surgical treatment.
Traditionally, gastric carcinoid type 1 (GCA1s) are endoscopically or surgically removed, depending on the number, appearance and size of the tumors. Antrectomy, with surgical excision of the majority of the G cells, is thought to facilitate regression of these tumors by removing the source of excessive gastrin secretion; however, the long-term benefits of antrectomy still remain uncertain. Although proton pump inhibitors are effective in reducing hypergastrinemia-induced gastric acid hypersecretion in GCA2, they do not affect ECL-cell hyperplasia, and therefore their role in GCA1 is limited. Moreover, in selected cases, significant reduction of hypergastrinemia does not prevent development of ECL carcinoid, suggesting that, in addition to hypergastrinemia, other pathogenic or genetic factors may be involved. Treatment with somatostatin analogues (SSA) might impede ECL-cell hyperplasia by suppressing gastrin secretion and/or by a direct anti-proliferative effect on ECL cells. Treatment with SSAs in GCA1 leads to a substantial tumor load reduction, with a concomitant decrease of serum gastrin levels. Published data indicate an important anti-proliferative effect of SSA on ECL cells, providing clinical benefit and obviating, at least temporarily, the need for invasive therapies for GCA1. Morphometric studies demonstrated that, while antrectomy specifically decreased the volume of ECL cells versus the total volume of endocrine cells, octreotide reduces the overall endocrine cell volume. Although the number of treated patients is small, it has been suggested that SSA may exert important anti-proliferative effects either directly, by inhibiting ECL-cells proliferation, or indirectly through suppression of gastrin hypersecretion.
