Clinical Pharmacology

Bioequivalence study of BAY 77-1931 orally disintegrating tablet

Trial purpose

The primary objective of this study was to establish the bioequivalence of two different tablet formulations containing BAY77-1931. The secondary objectives of this study were to assess the safety and tolerability, as well as to Investigate the plasma lanthanum concentration after BAY 77-1931 ODT 500 mg administration.

Primary Outcome

  • Pharmacodynamics: Daily urinary phosphate excretion (mmol) on each day
    Each study drug was administered as multiple dose over 4-days under fed conditions with a washout interval of at least 14 days in between. Twenty four hours urine collection were repeated 5 times from morning on Day -2 to that on Day 4.
