Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients who require screening colonoscopy will receive an intraluminal spraying of NPO-13 per contraction region of large bowel up to fifth times during the colonoscopy.

The efficacy of NPO-13 will be evaluated based on the proportion of the splayed region with no contraction after NPO-13 dosage (primary outcome measure). The colonic spasm will be assessed by an independent committee using recorded video images.

The safety of NPO-13 will be evaluated based on adverse events and adverse drug reactions (ADRs) observed between administration and seven days after administration.
