Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43614   clinical trials with a EudraCT protocol, of which   7207   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    4. Have symptomatic AF that has been sustained for greater than 3 days (72 hours) and less than 180 days (6 months) duration and is clinically indicated for cardioversion; subjects may have a mix of AF and atrial flutter if AF is predominant and was the presenting arrhythmia.
    5. Have adequate anticoagulant therapy for cardioversion in accordance standard of practice as recommended by ACC/AHA/ESC guidelines 8 or with local clinical practice (e.g. TEE algorithm);
    6. Be hemodynamically stable (90 mmHg < systolic blood pressure < 190 mmHg) at screening and on Day 1 before dosing (while taking rate control drugs, if required).
    7. Subject has a Body Mass Index (BMI) < 35
    E.4Principal exclusion criteria
    1. At screening, have known prolonged QT syndrome, familial Long QT syndrome, QTcF interval of >500 msec as measured on a 12-lead ECG while in AF; previous history of Torsade de Pointes, ventricular fibrillation, or sustained ventricular tachycardia (VT); After DC cardioversion and while in sinus rhythm, QTcF >440/450 ms for males/females, respectively.
    2. Have a QRS >0.130 sec.
    3. Previous episodes of second or third-degree atrioventricular block.
    4. Last DC cardioversion attempt occurred within 3 months and was unsuccessful (including IRAF); or any prior ablation for AF.
    5. Have persistent bradycardia with ventricular rate below 50 beats/min that in the opinion of the investigator is clinically significant, sick-sinus syndrome or pacemaker (including CRT, AICD). Have persistent tachycardia greater than 110 beats/min.
    6. Have clinically significant moderate or severe valvular stenosis, hypertrophic obstructive cardiomyopathy, restrictive cardiomyopathy or constrictive pericarditis.
    7. Have NYHA Class III or Class IV heart failure (HF) at screening or admission, have been hospitalized with HF or new diagnosis of HF in the previous 6 months; any change in HF medications within 2 months; NT-proBNP > 47 pmol/l; EF<45% obtained within two weeks prior to cardioversion.
    8. Have a myocardial infarction (MI), cardiac surgery, angioplasty, unstable angina or acute coronary syndrome within 30 days prior to entry into the study; Have serious pulmonary, hepatic (i.e. ALT >3X ULN), metabolic, renal (i.e. eGFR < 30mL/min), gastrointestinal, central nervous system (i.e. stroke or TIA within past 6 months) or psychiatric disease (e.g. drug addiction or alcohol dependence), end-stage disease states, or any other disease that in the opinion of the investigator could interfere with the conduct or validity of the study or compromise subject safety.
    9. Have known concurrent temporary secondary causes of AF such as alcohol intoxication, pulmonary embolism, hyperthyroidism, pneumonia, hypoxemia (oxygen saturation < 90% on room air), acute pericarditis, or myocarditis.
    10. Hypokalemia (K+ should be corrected prior to dosing).
    11. Have clinical evidence of digoxin toxicity.
    12. Have received a Class I or Class III antiarrhythmic agent (including sotalol) within 5 half-lives of randomization or amiodarone or dronedarone within 4 weeks.
    13. Have received treatment with other drugs known to prolong the QT interval within 5 half-lives, including, certain antidepressants (e.g. tricyclic antidepressants), certain antihistaminics (e.g. terfenadine, astemizole), certain antiinfectives (e.g. erythromycin), certain antipsychotics (e.g. haloperidol, pimozide, thioridazine, ziprasidone); certain cardiovascular non-antiarrhythmics (e.g. bepridil), certain gastro-intestinal agents (e.g. cisapride).
    14. Have any other surgical or medical condition that, in the judgment of the clinical Investigator might warrant exclusion or be contraindicated for safety reasons.
    15. Be concurrently participating in another investigational drug study or have received an investigational drug within 30 days or 5 half-lives prior to screening.
    16. Be unable to communicate well with the Investigator and to comply with the requirements of the entire study.
    17. Have received potent CYP2D6 or CYP3A inhibitors within 5 half-lives. Potent CYP2D6 include bupropion, fluoxetine, paroxetine, cinacalcet and quinidine. Potent CYP3A inhibitors include indinavir, nelfinavir, ritonavir, saquinavir, clarithromycin, telithromycin, itraconazole, ketoconazole, vorikonazole, posakonazole, and nefazodone
    E.5 End points
    E.5.1Primary end point(s)
    The objective of this study is to estimate the effects of K201 over 28 days on the following endpoints of interest:

    1. Time to first documented recurrence of symptomatic AF

    2. Time to first documented recurrence of symptomatic or asymptomatic AF
    3. Proportion of subjects in sinus rhythm on Day 28
    4. During 10 days of continuous Holter monitoring, Number of AF beats
    5. During 10 days of continuous Holter monitoring, Time in AF (atrial fibrillation defined as > 30 consecutive beats of AFib/flutter origin)
    6. Change in AF symptoms as assessed by the AF symptom checklist.
    7. Change in CCS-Severity of AF scale
    8. Days dead or in AF during 28 days
    9. Days dead or hospitalized during the 28 days
    10. Proportion of subjects with CV mortality or AF re-admission to day 28

    Safety and tolerability in randomised subjects will be continuously evaluated based on Adverse Events/Serious Adverse Events (AE/SAE) reporting and monitoring of laboratory evaluations, ECG and vital signs.

    Safety parameters will include:

    • Physical examinations, medical history, vital signs, ECG, standard laboratory test panels, and monitoring of adverse events.
    • ECGs assessments by 12-lead ECGs recorded at scheduled clinic visits. Holter/TTEM data will be read by an independent core lab.
    • Safety variables of particular interest include the hemodynamic parameters of blood pressure and heart rate as well as ECG parameters and analyses of QT, QTcB, QTcF, the incidence of Torsade des pointes, and other ventricular arrhythmias, including bradyarrhythmias.
