Device: Vitala
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: Phase II Vitala 12 Hour Wear Test With Convex Products

Further study details as provided by ConvaTec Inc.:

Primary Outcome Measures:
  • Safety [ Time Frame: 29 Days ]
    Assess safety during 12 hours of Vitala™ device wear with convex products by measuring the frequency of adverse events relating to the stoma (including gastrointestinal, stomal and surrounding skin events), and stomal vascularity.

  • Efficacy: [ Time Frame: 29 Days ]

    Restoration of Continence (absence of fecal leakage around the device) for 29 days of Vitala™ daily wear according to the following parameters:

    • Proportion of subjects with leakage over time.
    • Overall weighted leakage rate.
    • Proportion of subjects without leakage.
    • Self-rating of ability to restore continence.

Secondary Outcome Measures:
  • Efficacy [ Time Frame: 29 Days ]

    Vitala™ device will also be evaluated for the following efficacy parameters:

    • Security of the device.
    • Flange to flange security.
    • Device wear time.
    • Subject comfort.
    • Control of odor.
    • Control of noise due to flatus release from the stoma.
    • Ease of use of the device during application and removal.
    • Subject acceptance of the device.
