Condition(s) targeted: Hypertension

Intervention: Nifedipine/Candesartan (BAY 98-7106) (Drug); Nifedipine (Adalat, BAY A1040) and Candesartan (Atacand, BAY 12-9333) (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Bayer

Official(s) and/or principal investigator(s):
Bayer Study Director, Study Director, Affiliation: Bayer


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.

Clinical Details

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

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome:

Maximum drug concentration in plasma (Cmax) of nifedipine and candesartan

Area under the drug-concentration vs. time curve from time 0 to the last data point (AUC(0 tn)) of nifedipine and candesartan

Secondary outcome:

Area under the curve (AUC) of Nifedipine and Candesartan

Dose normalized Cmax (Cmax,norm) of Nifedipine and Candesartan

AUC normalized for dose and body weight (AUCnorm) of Nifedipine and Candesartan

Area under the plasma concentration-time curve from time zero to 48h (AUC(0-48))of Nifedipine and Candesartan

The time of the maximum concentration (Tmax) of Nifedipine and Candesartan

Half life (t1/2) of Nifedipine and Candesartan

The mean residence time (MRT) of Nifedipine and Candesartan

Oral plasma clearances (CL/F) of Nifedipine and Candesartan
