Postoperative Dumping Syndrome clinical trials

Study to Assess Safety and Efficacy of sc Pasireotide in Patients With Dumping Syndrome

Dumping Syndrome consists of (1) a too rapid gastric emptying, (2) an inappropriate release of GI hormones (as a reaction to the hyperosmolar contents in the duodenum) and (3) an hyperinsulinemic response to a too rapid absorption of glucose. Because it is not well known which somatostatin receptor(s) (sst1-5) influence(s) Dumping Syndrome most, the goal of this trial is to evaluate : - the effect of pasireotide (sst1, 2, 3, 5 agonist) on the control of gastric emptying. - the effect of pasireotide (sst1, 2, 3, 5 agonist) on the release of GI hormones (during OGTT). - the effect of pasireotide (sst1, 2, 3, 5 agonist) on the hyperinsulimic response (during OGTT). - the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of objective parameters of Dumping Syndrome (hematocrit (Hct), pulse rate and occurrence of hypoglycemia after an Oral Glucose Tolerance Test (OGTT) with 75g of glucose) - the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of overall symptoms as measured by the combined Dumping Syndrome score - the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of symptoms as measured by (a) early and (b) late phase dumping symptom score separately - the efficacy of pasireotide (sst1, 2, 3, 5 agonist) for control of quality of life (QoL SF-36)
