NCT ID: NCT03086356

Last Updated: 2019-03-08

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 12 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-05-10
• Study Completion Date: 2017-09-12

Brief Summary

The primary objective of the trial is to investigate the pharmacokinetics and pharmacodynamics of idarucizumab in Chinese healthy male and female subjects following intravenous administration of idarucizumab followed by idarucizumab with 15 minutes interval when administered at or close to the steady state of dabigatran.

Another objective of this trial is to explore the effect idarucizumab on the PK (pharmacokinetic(s)) and PD (pharmacodynamic) parameters of dabigatran.

Eligibility Criteria

Inclusion Criteria

• Age >= 18 and Age <= 45 years at screening
• Healthy male and female based upon a complete medical history, including vital signs (Blood Pressure, Pulse Rate, and Body Temperature), 12-lead Electrocardiogram and clinical laboratory tests. Women of childbearing potential must be ready and able to use highly effective methods of birth control per International Committee on Harmonisation M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the patient information.
• Body weight >=50 kg with body mass index range >=19.0 and <24.0 kg/m2 at Visit 1.
• Signed and dated written informed consent in accordance with Good Clinical Practice and local legislation prior to admission to the trial.

Exclusion Criteria

• Any finding of the medical examination (including Blood Pressure, Pulse Rate, Body Temperature and Electrocardiogram) is deviating from normal and judged as clinically relevant by the investigator
• Any evidence of a clinically relevant concomitant disease according to investigator's clinical judgement
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Surgery of the gastrointestinal tract that could interfere with kinetics of the trial medication (except appendectomy)
• Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
• History of relevant orthostatic hypotension, fainting spells or blackouts.
• Chronic or relevant acute infections
• History of relevant allergy/hypersensitivity (including allergy to drug or its excipients) or immune system disease
• Intake of drugs with a long half-life (> 24 hours) within at least 30 days or less than 10 half-lives of the respective drug prior to first trial drug administration
• Within 10 days prior to administration of trial medication, use of drugs that might reasonably influence the results of the trial or that might prolong the QT/corrected QT (QTc) interval.
• Participation in another trial with investigational drug administration within 60 days prior to first trial drug administration
• Smoker (> 10 cigarettes or > 3 cigars or > 3 pipes/day)
• Inability to refrain from smoking during hospitalization
• Alcohol abuse (consumption of more than 20 g per day: e.g., 1 middle-sized bottles of beer, 1 gou [equivalent to 180 mL] of sake))
• Drug abuse or positive drug screening
• Blood donation (400 mL whole blood donation within 12 weeks, 200 mL whole blood donation or blood component donation within 4 weeks) prior to first trial drug administration
• Intention to perform excessive physical activities within one week prior to first trial drug administration or during the trial
• Any laboratory values outside the reference range that are of clinical relevance according to investigator's clinical judgement
• Inability to comply with dietary regimen of trial site
• A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTcF interval >450 ms)
• A history of additional risk factors for torsades de points (TdP) (e.g., heart failure, hypokalemia, family history of Long QT Syndrome)
• Positive HIV (human immunodeficiency virus) test result at screening examination
• Positive testing for Hepatitis B Antigen and/or a positive Hepatitis C antibody test result at screening examination
• Subjects considered unsuitable for inclusion by the investigator, e.g. are unable to understand and comply with trial requirements, or have any condition which in the opinion of the investigator would not allow safe participation in the trial.
• Subjects who do not agree to minimize the risk of female partners becoming pregnant from the first dosing day until 12 weeks after the trial completion. Acceptable methods of contraception comprises barrier contraception and a medically accepted contraceptive method for the female (intra-uterine device with spermicide. hormonal contraceptive since at least 8 weeks)
• History or evidence of blood dyscrasia, haemorrhagic diathesis, severe thrombocytopenia, cerebrovascular haemorrhage, bleeding tendencies associated with active ulceration or overt bleeding of gastrointestinal, respiratory or genitourinary tract or any disease or condition with haemorrhagic tendencies (e.g. cerebral aneurysm, dissecting aorta, central nervous system (CNS) trauma, retinopathy, nephrolithiasis)
• Abnormal values for prothrombin time (PT), activated partial thromboplastin time (aPTT) and thrombocytes considered by the investigator or one of the co-investigators to be clinically relevant
• Creatinine and estimated glomerular filtration rate (GFR) outside the normal range
• Evidence of proteinuria
• Women who are pregnant, nursing, or who plan to become pregnant while in the trial
