Study of NPO-11 in Patients Undergoing Gastrointestinal Endoscopy

August 21, 2018 updated by: Nihon Pharmaceutical Co., Ltd

Phase Ⅲ Placebo-controlled Study of NPO-11 in Chinese Patients Undergoing Gastrointestinal Endoscopy

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.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The proportion of patients had no gastric peristalsis during the procedures
Time Frame: 15 minutes
No gastric peristalsis is defined as when patients have no gastric peristalsis at both 2 minutes post-dose and the end of endoscopy.(central evaluation by independent evaluator)
15 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in peristaltic movement
Time Frame: 15 minutes
The measure use peristaltic grade(central evaluation by independent evaluator).
15 minutes
Difficulty level of intra-gastric observation
Time Frame: 15 minutes
Subjective evaluation by investigator or subinvestigator who performs endoscopy
15 minutes
Correlation between the time from the dose to the end of endoscopy and peristaltic grade
Time Frame: 15 minutes
15 minutes
