Outcome Measures

Primary Outcomes (2)

  • Serum immunoglobulin-A (IgA) level

    IgA as an indicator for immunology, in assessing severity of upper respiratory illnesses between number of adult participants taking LCZ vs. placebo

    12 months

  • Bristol stool chart scale

    Bristol stool scale (from a scale of 1-7; scale of 1 representing hard lump, and 7 representing liquid with no solid pieces) as an indicator for assessing severity of gastrointestinal-related diarrheal illnesses between number of adult participants taking LCZ vs. placebo

    12 months

Secondary Outcomes (1)

  • Fecal microbiota profiling

    12 months

Study Arms (2)
