Bioequivalence Trial of Concor AM® vs Bisoprolol and Amlodipine in Chinese Participants

February 19, 2019 updated by: Merck KGaA, Darmstadt, Germany

A Randomized, Two-period Crossover Trial Examining Bioequivalence of Bisoprolol-Amlodipine 5 mg/5 mg Combination Tablets Versus Bisoprolol 5 mg Tablets and Amlodipine 5 mg Tablets Given Concomitantly in Healthy Subjects in Fasting and Fed State

This is a Phase I, open-label, randomized, 2-period, 2-sequence, crossover study to demonstrate bioequivalence (BE) between the bisoprolol-amlodipine fixed-dose-combination (FDC) tablet (investigational product) and bisoprolol and amlodipine tablets administered concomitantly (comparators) given as a single oral dose in fasting and fed state.

AUCextra% was calculated as area under the curve from time tlast extrapolated to infinity given as percentage of AUC 0-infinity. Here, tlast is the last sampling time at which the concentration is at or above the lower limit of quantification.
Pre-dose (Baseline) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 24, 36, 48, 72, 96, 120, 144 and 168 hours post-dose for each treatment period

Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, AEs Leading to Death, and AEs Leading to Discontinuation
Time Frame: Baseline up to Day 29
An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. An AE was considered as 'treatment emergent' if it occurred after the first drug administration of each period or if it was present prior to drug administration but exacerbated after the drug administration. TEAEs included both Serious TEAEs and non-serious TEAEs.
