Bayer
  Purpose
Single dose study of BAY85-3934 compared to placebo in young/elderly male and female healthy subjects. The main focus of the study is to determine if the pharmacokinetics (drug levels in blood) of BAY85-3934 is similar or not in the four subject groups. Qualifying subjects will be dosed with a single tablet of BAY85-3934 (or placebo) and blood will be drawn over 4 days. The safety and tolerability of BAY85-3934 compared to placebo will also be evaluated over the 5 days of the study.

Condition Intervention Phase
Anemia Drug: BAY85-3934 Drug: Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Basic Science
Official Title: A Parallel Group, Double-Blind Study to Evaluate the Effects of Age and Gender on the Single-Dose Pharmacokinetics of BAY85-3934, Tablet Formulation

Further study details as provided by Bayer:

Primary Outcome Measures:
  • Area under the plasma concentration vs time curve from zero to infinity after single (first) dose of BAY85-3934 [ Time Frame: Measured over 72 hours after dosing ]
  • Maximum drug concentration in plasma after single dose administration of BAY85-3934 [ Time Frame: Measured over 72 hours after dosing ]
  • Safety and tolerability of BAY 85-3934 after single dose administration as determined by physical examination (changes from baseline) [ Time Frame: Measured over 96 hours after dosing ]
  • Safety and tolerability of BAY 85-3934 after single dose administration as determined by adverse events monitoring (number of subjects with a specific event) [ Time Frame: Measured over 96 hours after dosing ]
  • Safety and tolerability of BAY 85-3934 after single dose administration as determined by electrocardigram and and vital sign measurememnt (changes from baseline) [ Time Frame: Measured over 72 hours after dosing ]
  • Safety and tolerability of BAY 85-3934 after single dose administration as determined by laboratory testing (changes from baseline) [ Time Frame: Measured over 48 hours after dosing ]

Secondary Outcome Measures:
  • Pharmacodynamic effects on erythropoietin as the change from baseline at 48 hours [ Time Frame: 48 hours post dose ]
  • Pharmacodynamic effects on reticulocytes as the change from baseline at 96 hours [ Time Frame: 96 hours post dose ]
  • Pharmacodynamic effects on hemoglobin as the change from baseline at 48 hours [ Time Frame: 48 hours post dose ]
  • Pharmacodynamic effects on hematocrit as the change from baseline at 96 hours [ Time Frame: 96 hours post dose ]
  • Pharmacodynamic effects on vascular endothelial growth factor (VEGF) as the change from baseline at 96 hours [ Time Frame: 96 hours post dose ]
