|
E.2.2 | Secondary objectives of the trial |
Protocol 1: The secondary objectives are to investigate the effects of vildagliptin on: - frequency of beta-cell replication - frequency of beta-cell apoptosis - beta-cell mass - first-, second-phase and arginine-induced insulin secretion - oral glucose tolerance - insulin sensitivity
Protocol 2 (Study Extension): The secondary objectives are to investigate the effects of vildagliptin on: - oral glucose tolerance - glucagon/insulin secretion

Protocol 1: (1) Age between 18 and 80 years, inclusive. (2) Elective partial pancreatic surgery has been recommended for medical reasons by reason of benign pancreatic diseases (e.g. chronic pancreatitis, pancreatic cysts, pancreatic duct obstruction, benign focal pancreatic lesions) and has been scheduled for a date later than 14 weeks after enrollment by the attending physician (protocol 1)or has been performed one day prior to study enrollment (protocol 2).

(4) Patients have an HbA1c not exceeding 10.0% and fasting plasma glucose not exceeding 240 mg/dl. (5) Female patients are not breastfeeding, and female patients of childbearing potential (not surgically sterilized and between menarche and 1-year postmenopause): 1. test negative for pregnancy at the time of screening based on a blood serum test, 2. intend not to become pregnant during the study, and 3. agree to use a reliable method of birth control (for example, oral contraceptives; a reliable barrier method of birth control [diaphragms with contraceptive jelly; cervical caps with contraceptive jelly; condoms with contraceptive foam; intrauterine devices]; partner with vasectomy) during the study, as determined by the investigator.
Protocol 2: (1) Age between 18 and 80 years, inclusive. (2) Partial pancreatectomy (excluding total pancreatectomy) has been performed for benign pancreatic disease prior to study enrollment (protocol 2).

(4) Female patients are not breastfeeding, and female patients of childbearing potential (not surgically sterilized and between menarche and 1-year postmenopause): 1. test negative for pregnancy at the time of screening based on a blood serum test, 2. intend not to become pregnant during the study, and 3. agree to use a reliable method of birth control (for example, oral contraceptives; a reliable barrier method of birth control [diaphragms with contraceptive jelly; cervical caps with contraceptive jelly; condoms with contraceptive foam; intrauterine devices]; partner with vasectomy) during the study, as determined by the investigator.
