Brief Summary:
The study is designed to investigate the safety, tolerability and efficacy of DG3173 in untreated acromegaly patients. Twenty patients received ascending single doses of DG3173 and one dose of octreotide, the current gold standard of medical therapy for acromegaly, with each patient receiving all doses of DG3173 as well as octreotide.
