Randomized, open label, single dose, 2-way crossover study to investigate the bioequivalence of a new fixed dose combination (FDC) tablet of nifedipine GITS and candesartan with the corresponding loose combination under fed conditions.

Condition Intervention Phase
Hypertension, Essential
Drug: Nifedipine/Candesartan (BAY 98-7106)
Drug: Nifedipine (Adalat, BAY A1040) and Candesartan (Atacand, BAY 12-9333)
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Bio-equivalence Study
Intervention Model: Crossover Assignment
Masking: Open Label
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 and the Loose Combination of Both Components and to Investigate the Bioequivalence Between the Fixed Dose and the Loose Combination in Healthy Male Subjects Under Fed Conditions in an Open Label, Randomized, 2-way-crossover Design

Primary Outcome Measures:
  • Cmax [ Time Frame: within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Maximum drug concentration in plasma after dose administration for nifedipine and candesartan

  • AUC(0-tlast) [ Time Frame: within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Area under the drug-concentration vs. time curve from time 0 to the last data point for nifedipine and candesartan

Secondary Outcome Measures:
  • AUC [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Area under the curve from time 0 to infinity after single dose for nifedipine and candesartan

  • Cmax,norm [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Dose normalized Cmax for nifedipine and candesartan

  • AUCnorm [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    AUC normalized for dose and body weight for nifedipine and candesartan

  • AUC(0-48) [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Area under the plasma concentration-time curve from time zero to 48h for nifedipine and candesartan

  • Tmax [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    The time of the maximum concentration for nifedipine and candesartan

  • t1/2 [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Half-life for nifedipine and candesartan

  • MRT [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    The mean residence time for nifedipine and candesartan

  • CL/F [ Time Frame: Within 48 hours after each dosing ] [ Designated as safety issue: No ]
    Oral plasma clearances for nifedipine and candesartan

  • Number of participants with adverse events [ Time Frame: Approximately 3-7 weeks per subject ] [ Designated as safety issue: Yes ]
