Paraoxanase 1 clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT03646019 Not yet recruiting - Clinical trials for Coronary Artery Disease

Serum Oxidative Status as a Potential Predictor of Coronary Artery Disease.

Start date: September 2018
Phase:
Study type: Observational

Coronary artery disease (CAD) is a major cause of death and disability in developed countries.Human studies revealed a significant association between serum oxidative status using PON1, TBARS and thiol levels and the presence of CAD and its severity. However, these studies were addressing the severity of CAD depending on coronary angiography of patients presenting with ST elevation myocardial infarction, Non ST elevation myocardial infarction, unstable angina pectoris, while part of them even had a history of CAD. Others where admitted for an elective coronary angiography for suspected stable CAD while only few patients were assessed for atypical chest pain. This study thus aims to assess the relationship between PON1 activity, TBARS and thiol levels and the existence of CAD and its severity in patients with no previous history of CAD presenting to the emergency department (ED) with acute chest pain but with no evidence of acute myocardial infarction or acute E.C.G ischemic changes. Assessment with a Cardiac CT scan instead of coronary angiography will allow the investigators to study the status of coronary atherosclerosis and calcium burden in all participants, including those presenting with atypical chest pain that most probably will not be referred by physicians to a coronary angiography. Further sub groups analysis will estimate this relationship particularly in low-intermediate risk groups depending on 3 different validated scoring systems - TIMI, GRACE and HEART score.
