  Purpose

Endonase, a kind of protease, is known to cause both extensive degradation of mucins and a reduction in mucus viscosity. As part of the search for more effective forms of therapy against H. pylori when it colonizes not only the surface of the surface mucosal cells but also the surface mucous gel layer covering the mucosal surface of the stomach. The investigators decided to investigate whether or not endonase might have additive effect of pronase on the efficacy of eradication therapy against Helicobacter pylori.

Further study details as provided by Chuncheon Sacred Heart Hospital:

Primary Outcome Measures:
  • Eradication rate [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Intention-to-treat analysis and per-protocol analysis to compare the eradication rate of the 7-day standard PPI-based triple therapy plus endonase with that of the 7-day standard PPI-based triple therapy


Secondary Outcome Measures:
  • Number of participants with adverse events [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]
    Difference in the number of participants with adverse events between patients receiving standard triple therapy plus endonase and patients receiving control treatment

  • Number of participants taking over 85% of medicine [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Difference in the number of participants taking over 85% of medicine between patients receiving standard triple therapy plus endonase and patients receiving control treatment
