Study of NPO-11 in Patients Undergoing Gastrointestinal Endoscopy

Phase 3
Completed
Conditions
Patients Undergoing Gastrointestinal Endoscopy
Interventions
Drug: NPO-11
Drug: Placebo
Registration Number
NCT03263910
Lead Sponsor
Nihon Pharmaceutical Co., Ltd
Brief Summary

Chinese patients who require gastrointestinal endoscopy will receive an intra-gastric single dose of NPO-11 20ml. The superiority of NPO-11 compared to placebo as a premedication for endoscopy will be verified in a randomized, double-blind, parallel-assignment design based on the proportion of patients having no gastric peristalsis.

The safety of NPO-11 will be evaluated based on adverse events and adverse drug reactions observed between informed consent and 7 days after administration in comparison with the placebo group.
