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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main objective of this study is:

    E.2.2Secondary objectives of the trial
    Secondary objectives of the trial are:
    1. To determine if CGT-2168 compared to clopidogrel increases the time to discontinuation of study medication due to gastrointestinal signs or symptoms in the setting of concomitant aspirin.

    2. To determine if CGT-2168 compared to clopidogrel increases the time to development of gastroesophageal reflux disease/erosive esophagitis and dyspepsia, in the setting of concomitant aspirin.

    3. To evaluate the safety of CGT-2168 compared to clopidogrel, in the setting of concomitant aspirin.
    E.2.3Trial contains a sub-study No

Specific conditions that may confer a need for long-term clopidogrel + aspirin therapy may include non-ST segment elevation acute coronary syndrome (unstable angina/non-Q-wave MI), ST segment elevation acute MI), or new placement of a coronary artery stent.
    • Age ≥ 21 years. No more than 40% of participants will be less than 65 years of age at randomization.

    • Requirement for current or chronic use of a proton pump inhibitor, H2 receptor blocker, sucralfate or misoprostol.
    • Erosive esophagitis, esophageal or gastric variceal disease, or non-endoscopic gastric surgery. Patients with a history of GERD/erosive esophagitis or dyspepsia who do not currently require proton pump blockers will be eligible.
    • Receipt of > 21 days of clopidogrel or another thienopyridine prior to randomization.
    • Oral anticoagulation with vitamin K antagonists (coumarins) that cannot be safely discontinued for duration of study.
    • Recent fibrinolytic therapy (for fibrin-specific and nonfibrin-specific agents, administration < 24 hours and < 48 hours before randomization, respectively).
    • Scheduled percutaneous coronary intervention (PCI). Patients may be enrolled upon completion of PCI.
    • Recent (< 30 days prior to randomization) or scheduled coronary artery bypass graft (CABG) surgery.
    • Cardiogenic shock at the time of randomization, refractory ventricular arrhythmias, or congestive heart failure (New York Heart Association class IV).
    • Active pathological bleeding or a history of hereditary or acquired hemostatic disorder.
    • History of hemorrhagic stroke, intracranial neoplasm, arteriovenous malformation or aneurysm.
    • Platelet count < 100,000/mL at screening.
    • Anemia (hemoglobin < 10 g/dL) at screening.
    • Systemic corticosteroids except low-dose oral corticosteroids equivalent to prednisone ≤ 5 mg/day.
    • Allergy or contraindication to clopidogrel or other thienopyridine drugs, omeprazole or other proton pump inhibitor drugs, aspirin or salicylate derivatives, or other study drug ingredients.
    • Treatment within 30 days prior to randomization with any investigational drug or device including investigational (not approved) coronary artery stents, or currently enrolled in another interventional drug or device study.
    • Women who are pregnant or breastfeeding.
    • Life expectancy less than 12 months.
    • Clinically significant laboratory abnormality at screening or any other condition that, in the opinion of the Investigator, precludes participation in the study.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the time from randomization to first occurrence of a composite endpoint of upper gastrointestinal clinical events, including:
    1. Upper gastrointestinal bleeding, including bleeding of gastroduodenal origin and acute upper gastrointestinal bleeding of unknown origin;
    2. Bleeding of presumed occult gastrointestinal origin with documented decrease in hemoglobin of ≥ 2 g/dL or decrease in hematocrit ≥ 10% from baseline;
    3. Symptomatic gastroduodenal ulcer confirmed by endoscopy or radiography without evidence of gastrointestinal bleeding;
    4. Persistent pain of presumed gastrointestinal origin (duration ≥ 3 days) with underlying multiple erosive disease (5 or more gastroduodenal erosions, excluding mucosal hemorrhages), confirmed by endoscopy;
    5. Obstruction; or
    6. Perforation.

    There will be one formal interim analysis for efficacy. This will be reviewed by the independent DMC who may recommend stopping the study if the efficacy stopping criterion is achieved.
