Measure
Octreotide, Then Ascending DG3173
Interventions: octreotide and DG3173. Eligible patients are to receive 300 µg octreotide as active comparator, followed by four ascending doses of 100 µg, 300 µg, 900 µg and 1800 µg DG3173. All treatments will be administered consecutively to all patients as single subcutaneous bolus injections.
