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).
(3) Presence of either impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or diabetes mellitus (DM) according to ADA criteria.
(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).
(3) Patients have an HbA1c not exceeding 10.0% and fasting plasma glucose not exceeding 240 mg/dl.

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.

(10) Patients have ongoing alcohol consumption (>20 g daily for males and >10 g daily for females).
(11) Patients have Galactose intolerance, Lapp lactase deficiency or Glucose- Galaktose-malabsorption.
(11) Patients have had greater than three episodes of severe hypoglycemia within 3 months prior to screening.
(12) Patients are undergoing therapy for a malignancy, other than basal cell or squamous cell skin cancer.

contained in these agents.

(16) Patients have known haemoglobinopathy or chronic anemia.
(17) Patients are receiving chronic (lasting longer than 2 weeks) systemic glucocorticoid therapy (excluding topical and inhaled preparations) or have received such therapy within 2 weeks immediately prior to screening.
Protocol 2:
