Effectiveness of 'Nexpowder' for Hemostatic Treatments of Nonvariceal, Upper Gastrointestinal Bleeding

2019-10-17 11:03:40 | BioPortfolio


A prospective, multi-center, multi-national, randomized controlled trial to evaluate safety and effectiveness of endoscopic hemostatic powder, 'Nexpowder' for hemostatic treatments of nonvariceal upper gastrointestinal bleeding.

This study is a prospective, multi-national, multi-center, single blind (for patients), controlled investigation planned to evaluate safety and effectiveness of Nexpowder with 352 subject patients.


This investigational study is designed to compare effectiveness of using the standard-of-care hemostatic therapy only, versus the standard-of-care hemostatic therapy plus an additional hemostatic treatment using Nexpower for patients with nonvariceal, upper gastrointestinal bleeding from ulcers with high-risk stigmata (Forrest classification Ia, Ib, or IIa).

The primary end-points will be evaluated by assessing the rates of re-bleeding, which occur over three (3) days following initial hemostasis achieved with the standard-of-care hemostatic therapy.

Secondary end-points consist of evaluating three items: 1) Ease of use of Nexpowder applied for the test group after reaching initial hemostasis, 2) Nexpowder device malfunction and 3) safety follow-up to check occurrence of adverse event(s)/re-bleeding at 30-day (+5) time point.

Only the subjects whose initial hemostasis has been achieved will be registered for this investigation but those who initial hemostasis has failed to be reached with the standard-of-care therapie(s) shall not be registered for this investigation.

Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
