Summary

Hypothesis: Oral administration of the oxalate metabolizing enzyme Oxazyme (OC4) will degrade food-borne oxalate and hence prevent its absorption from the gastrointestinal tract. In addition, by reducing oxalate concentrations in the gastrointestinal fluid, oxalate secretion from blood to the intestinal tract may be increased. Both effects would decrease blood levels of oxalate, and hence oxalate excretion in the urine.

Conditions

  • Hyperoxaluria

Interventions

DRUG

Oxazyme

Oxazyme (registered trademark) is a non-systemic orally delivered drug composed of recombinant oxalate decarboxylase (OxDC). It is formulated to enzymatically degrade available dietary oxalate prior to its absorption. Dosing: 1gm Oxazyme containing approximately 1600 Units OxDC in a sachet administered BID together with lunch and dinner. Subjects were instructed to open the oxazyme sachets and either sprinkle on food or add to a glass of water or fruit juice and consume the contents with a meal twice daily.
