Feasibility Study of a Novel Single Use Robotic Colonoscopy System

October 28, 2019 updated by: Bio-Medical Engineering (HK) Limited

A Pilot, Prospective, Non-randomized Study to Evaluate the Safety and Feasibility of Novel Single Use Robotic Colonoscopy System ("NISInspire-C System") in Human Subjects

This is a single centre, non-randomized, tandem colonoscopy trial of the NISInspire-C System, followed immediately by a conventional colonoscope (CC). Each trial subject will undergo colonoscopy using the NISInspire-C system, followed immediately by CC. The purpose of this study is to obtain observational data on the safety profile, feasibility and usability of the NISInspire-C System in performing diagnostic colonoscopy in human subjects. The level of procedural pain experienced by subjects will also be explored.

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

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

40 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: Subjects Receiving Colonoscopy
Subjects receiving tandem colonoscopies using the NISInspire-C System followed by a Conventional Colonoscopy
Device: NISInspire-C System
The NISInspire-C System is a disposable robotic colonoscopy system that consists of a flexible slender insertion tube designed to ensure non-invasive, reliable and safe colorectal screening. It comprises of two components: NISInspire-C Console, and the NISInspire-C Disposable Colonoscope.

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.
