Information provided by (Responsible Party):
Bayer
  Purpose
Randomized, open label, single dose, 4-way crossover study to investigate the bioequivalence of a new fixed dose combination tablet of nifedipine GITS and candesartan with the corresponding loose combination and to compare it with the individual drugs

Condition Intervention Phase
Hypertension, Essential Drug: Nifedipine-candesartan FDC (BAY 98-7106) Drug: Nifedipine GITS (Adalat LA, BAYA1040) Drug: Candesartan (Atacand) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Single Dose Study to Compare the Pharmacokinetics as Well as Safety and Tolerability of a Novel Fixed Dose Combination of Nifedipine GITS and Candesartan, the Loose Combination of Both and the Single Components Alone and to Investigate the Bioequivalence Between the Fixed Dose and the Loose Combination in Healthy Male Volunteers Under Fasting Conditions in an Open Label, Randomized, 4-way-crossover Design

Primary Outcome Measures:
  • Cmax [ Time Frame: Within 48 hours after each treatment ]
    Maximum drug concentration in plasma after dose administration for nifedipine and candesartan

  • AUC(0-tn) [ Time Frame: Within 48 hours after each treatment ]
    AUC from time 0 to the last data point for nifedipine and candesartan


Secondary Outcome Measures:
  • AUC [ Time Frame: Within 48 hours after each treatment ]
    Area under the plasma concentration vs time curve from zero to infinity after single (first) dose for nifedipine and candesartan

  • Cmax,norm [ Time Frame: Within 48 hours after each treatment ]
    Maximum drug concentration in plasma after dose administration divided by dose (mg) per kg body weight for nifedipine and candesartan

  • AUCnorm [ Time Frame: Within 48 hours after each treatment ]
    Area under the curve divided by dose per kg body weight for nifedipine and candesartan

  • AUC(0-48) [ Time Frame: Within 48 hours after each treatment ]
    AUC from time 0 to time 48 h for nifedipine and candesartan

  • tmax [ Time Frame: Within 48 hours after each treatment ]
    Time to reach maximum drug concentration in plasma after single (first) dose for nifedipine and candesartan

  • t½ [ Time Frame: Within 48 hours after each treatment ]
    Half-life associated with the terminal slope for nifedipine and candesartan

  • MRT [ Time Frame: Within 48 hours after each treatment ]
    Mean residence time for nifedipine and candesartan

  • CL/f [ Time Frame: Within 48 hours after each treatment ]
    Total body clearance of drug from plasma calculated after oral administration (apparent oral clearance) for nifedipine and candesartan

  • Number of participants with adverse events [ Time Frame: Approximately 3.5 months ]
