Official Title: A Pilot Study of Oxalate Absorption in Secondary Hyperoxaluria

Brief Summary: Identify individuals with greater absorption of oxalate based on increase in urinary oxalate excretion in response to a controlled oxalate-rich test meal.

Detailed Summary:

This is a prospective uncontrolled study in subjects with secondary hyperoxaluria. Subjects will visit the research center three times for outpatient visits (Screening, Test Day 3, Day 4).

Subjects will perform three 24-hour urine collections during Screening, Baseline Day 2, and Test Day 3. Test Day 3 includes the oxalate-rich test meal and the subject will collect a 24-hour urine separated into 4 urine collection intervals that are timed in relation to the oxalate-rich test meal (Pre-test meal, 4-hr and 6-hr post test meal and remaining time to 24-hours).

Current Primary Outcome: Percent oxalate absorption from oxalate-rich test meal, urinary oxalate (mg/24-hour) [ Time Frame: 24-hours ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Percent oxalate absorption 4-hours, 6-hours post oxalate-rich test meal and 24-hour. (mg/interval) [ Time Frame: 24-hours ]
  • Percent change from baseline urinary oxalate (mg) for each collection interval. [ Time Frame: 24-hours ]


Original Secondary Outcome: Same as current
