Who may be able to join

  • Inpatients or outpatients of either sex who require therapeutic upper gastrointestinal endoscopy and meet criteria (1), (4), (6) and one from (2), (3) or (5) in the study. Patients have to provide written informed consent for voluntary participation in the study.

  • Patients with a gastric adenoma (≤2 cm in size, no ulcer finding, EMR or ESD)
  • Patients with an a single intended lesion for the treatment
  • Patients without experience of PEG tube placement in case of PEG tube placement
  • Patients who are older than 20 years at the time of consent

Who cannot join

  • Patients who meet any of the following criteria will be excluded from the study beforehand. The criteria (3) and (4) will be confirmed by the endoscopic observation just before starting the intended treatment.
  • Patients with a history of surgery to the upper gastrointestinal tract
  • Patients who require emergency endoscopy
  • Patients with severe gastric stenosis or deformation which makes observation of gastric peristalsis difficult
  • Patients who require emergency endoscopic treatment except for the intended lesion
  • Patients with an ongoing cancer treatment (chemotherapy or radiotherapy)

About this study

Patients who require therapeutic upper gastrointestinal endoscopy, such as polypectomy, endoscopic hemostasis, percutaneous endoscopic gastrostomy (PEG), endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), will receive an intragastric spraying of NPO-11. The efficacy of NPO-11 as an anti-peristaltic agent for the endoscopic therapeutic procedures will be evaluated based on the proportion of patients with suppressed gastric peristalsis during the procedures. The degree of gastric peristalsis is assessed by an independent committee.

The safety of NPO-11 will be evaluated based on adverse events and adverse drug reactions (ADRs) observed between administration and seven days after administration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The proportion of patients had no or mild peristalsis during the therapeutic procedures

    No or mild gastric peristalsis is defined as when patients have no or suppressed gastric peristalsis during the therapeutic procedure (for 45 s). The degree of gastric peristalsis in the time periods is assessed by an independent committee.

    Measured: 60 minutes

Secondary outcomes (3)
  1. Duration of peristalsis-suppressing effect

    Measured: 60 minutes

  2. Difficulty level of the therapeutic procedure

    Measured: 60 minutes

  3. Adverse events and adverse drug reactions

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Menthol in people with Gastric Cancer and Colon Nos Polypectomy Tubular Adenoma, run by Nihon Pharmaceutical Co., Ltd at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The proportion of patients had no or mild peristalsis during the therapeutic procedures (time frame: 60 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2012.
