Brief Title
The Effect of Subcutaneous Infusions of 3 Doses of DG3173 on Growth Hormone Levels in Untreated Acromegalics
Official Title
The Effect of Subcutaneous Infusions of 3 Doses of a Novel Somatostatin Analogue, DG3173, on Growth Hormone Levels in Untreated Acromegalics
Brief Summary
This study is designed to assess the effect of the different continuous s.c. infusion treatments on the human growth hormone (hGH) levels in untreated acromegalic patients in comparison to a standard dose of octreotide. In addition, the pharmacokinetic profile and the safety and tolerability of DG3173 after continuous s.c. infusion will be evaluated.
Study Phase
Phase 2
Study Type
Interventional
Primary Outcome
The Number of Patients Who Achieve a Trough Human Growth Hormone (hGH) Concentration of <2.5µg/L During the Last 12 Hours of the 23 Hour Profile Following Each Study Treatment.
Condition
Acromegaly
Intervention
saline
Study Arms / Comparison Groups
Saline, then DG3173, then octreotide
Description: Interventions: saline, DG3173 and octreotide. Eligible patients are to receive a constant 23 hour subcutaneous infusion of saline as placebo comparator and will be randomized in an equal ratio to one of three treatment sequences of doses of 920, 2760 and 5520 µg DG3173 by constant 23 hour subcutaneous infusions in a random sequence followed by three subcutaneous injections of 300 µg octreotide at approximately 8 hour intervals as an active comparator.
