E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To assess the effect of temanogrel on MVO following PCI |
|
E.2.2 | Secondary objectives of the trial |
1. To assess the effect of temanogrel on selected coronary physiology indices and angiographic measures following PCI 2. To assess the effect of temanogrel on myocardial injury following PCI; 3. To assess the pharmacokinetics (PK) of temanogrel and its active metabolites AR295980 (M1) and AR295981 (M2) in subjects undergoing PCI; 4. To assess the safety and tolerability of temanogrel in subjects undergoing PCI |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Stable angina patients suitable for elective PCI or patients suitable for PCI for diagnosis of NSTEMI/UA. NSTEMI/UA patients are to be consistently hemodynamically stable until the time of PCI and have a thrombolysis in myocardial infarction (TIMI) Flow Grade (TFG) 2 or 3 on the diagnostic angiography - Target lesions for PCI must appear suitable for stenting as confirmed on the diagnostic angiography. Acceptable lesions cannot be in the left main artery or in a vein or arterial graft, or be a chronic total occlusion or in-stent restenosis. Two or more sequential lesions may be treated in the same artery, as long as they are treated in the same session and at least one of the lesions meets inclusion criteria - Both men and women (30 to 80 years of age, inclusive) participants agree to use a highly effective method of birth control throughout the entire study period, from informed consent through the adverse event reporting period, if the possibility of conception exists |
|
E.4 | Principal exclusion criteria |
- Planned or anticipated use of rotational atherectomy/ablation or shockwave therapies during the PCI procedure; - Any history of stroke, seizure, intracranial bleeding, or intracranial aneurysm; - Transient ischemic attack within the 6 months prior to Screening; - History of major trauma, major surgery, and/or clinically significant head injury or hemorrhage within the last 6 months of Screening; - NSTEMI/UA with subsequent cardiac troponin levels that are increasing (not stable or dropping) as shown by the 2 most recent measures after diagnosis of NSTEMI/UA and prior to randomization; - Any ST-elevation myocardial infarction (STEMI) within 10 days of Screening or STEMI within the target vessel territory within the last 6 months of Screening (eg, a patient with a NSTEMI because of a lesion in a diagonal may not be included if there is a history of anterior STEMI due to left anterior descending artery lesion that occurred within the last 6 months); - Known history of heart failure with reduced ejection fraction (HFrEF) defined as left ventricular ejection fraction ≤ 40% prior to current hospital admission |
