Brief summary
This is a single-centre, single-dose, dose-escalation, placebo and positive drug-controlled Phase I clinical study in healthy Chinese subjects to evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic profile of octreotide injection in healthy Chinese subjects.
Detailed description
This single centre study will be comprised of 6 cohorts. The single ascending dose part is comprises of 4 cohorts（5 mg, 10 mg, 20 mg, 30 mg). The other 2 cohorts are octreotide long-acting release ( Sandostatin LAR® ) 20 mg and Sandostatin® 0.1 mg.
