Overview
Brief Summary
This is a randomized, single-blind, placebo-controlled, parallel-group, multicentre study in patients with CAD. The study will be conducted at approximately 10 centres in 3 countries. Approximately 138 CAD patients will be randomized to AZD5718 or placebo (treatment duration 12 weeks).
Detailed Description
This is a randomized, single-blind, placebo-controlled, parallel-group, multicentre study in patients with CAD. The study will be conducted at approximately 10 centres in 3 countries (Denmark, Finland and Sweden). Patients suitable for the study will be identified and screened for eligibility after being hospitalized for Acute Coronary Syndrome (ACS) (Visit 1) comprising ST Elevation Myocardial Infarction (STEMI) or Non-ST Elevation Myocardial Infarction (non-STEMI). At Visit 1, after signing informed consent, study measurements will take place at days 1, 2, 3 and 5 post ACS, where feasible. It is planned that approximately 138 CAD patients will be randomized to ensure at least 66 evaluable patients receiving AZD5718 Dose B or placebo are included with 12 weeks treatment. For supporting dose selection in future studies, a treatment arm with 28 randomized patients receiving AZD5718 Dose A is included in the study. The study was originally designed to be a 4-week study and was amended to be a 12-week study. Therefore, the total number of patients is greater than required for a 12 weeks study (about 100), since some patients will only have 4 weeks of treatment. An evaluable patient is defined as a patient with a valid Coronary Flow Velocity Reserve (CFVR) measurement at Visit 2 and one post baseline visit as judged by the CFVR Core lab. On Day 1 (Visit 2), 7 to 28 days after the ACS event, patients willing to participate in the study will complete the screening procedure and, if eligible, be randomized. Treatment duration will be 12 weeks. During the treatment phase, patients will come in to the clinic for study measurements at 2 weeks (visit 3), 4 weeks (visit 4), 8 weeks (visit 4b) and 12 weeks (visit 4c). A follow-up visit (Visit 5) will be performed at 4 weeks (±4 days) after last dose in order to ensure safety and well-being of the patients
