What researchers measure

Primary outcomes

  1. Percent change from baseline in 24-hour urinary oxalate excretion during Weeks 1-4

    Efficacy will be assessed based on percent change from baseline to the mean of Weeks 1-4, derived from all 24-hour collections during Weeks 1-4 on treatment

    Time frame: 4 weeks

Secondary outcomes

  1. Proportion of subjects with a ≥ 20% reduction from Baseline in 24-hour urinary oxalate excretion during Weeks 1-4

    Efficacy will be assessed based on proportion of subjects with ≥ 20% reduction from baseline to the mean of Weeks 1-4, derived from all 24-hour collections during Weeks 1-4 on treatment

    Time frame: 4 weeks
