Further study details as provided by EndoGastric Solutions:

Primary Outcome Measures:
  • Typical and atypical Gastroesophageal Reflux Disease (GERD) symptom elimination [ Time Frame: 12 or 24 months ] [ Designated as safety issue: No ]
    Typical and atypical GERD symptom elimination (scores ≤ 2 to each question in GERD Health-related Quality of Life (GERD-HRQL), GERD Symptom Score (GERSS) and Reflux Symptom Index (RSI) questionnaires) at the follow-up.


Secondary Outcome Measures:
  • Serious Adverse Events (SAEs) & Unanticipated Adverse Device Effects (UADEs) [ Time Frame: 12 or 24 months ] [ Designated as safety issue: Yes ]
    The treatment will be considered safe if the incidence of serious adverse events (SAEs) is below the ranges reported for laparoscopic fundoplication.

  • Elimination of Proton Pump Inhibitors (PPIs) use [ Time Frame: 12 or 24 months ] [ Designated as safety issue: No ]
    Complete discontinuation will be considered clinically significant.

  • Healing of reflux esophagitis [ Time Frame: 12 or 24 months ] [ Designated as safety issue: No ]
    One grade reduction will be considered clinically significant.

  • Reduction of hiatal hernia [ Time Frame: 12 or 24 months ] [ Designated as safety issue: No ]
    Size reduction to < 1 cm will be considered clinically significant.

  • Normalization or clinically significant improvement in esophageal acid exposure and reflux episodes [ Time Frame: 12 or 24 months ] [ Designated as safety issue: No ]
    Esophageal acid exposure will be measured objectively by 48-hour Bravo pH or 24-hour impedance/pH testing at the follow-up (where pH testing is available). Normalization of esophageal acid exposure will be defined by total time with pH < 4 for ≤ 6% of 24-hour or for ≤ 5.3% of 48-hour monitoring period. The number of reflux episodes of ≤ 44 per each 24-hour period will be considered normal.
