Description of intervention(s) / exposure
This study is designed to evaluate the safety and efficacy of rivaroxaban in subjects with recent Acute Coronary Syndrome who are receiving background low-dose aspirin therapy (75 to 100 mg/day) without the intention to use a thienopyridine therapy or with thienopyridine therapy.

There will be 2 stages. Stage 1 will be for dose escalation while Stage 2 will be for dose confirmation.

In Stage 1 there will be 3 total daily dose levels of rivaroxaban or placebo. 5 mg (2.5 mg twice a day or 5 mg once daily), 10 mg (5 mg twice a day or 10 mg daily) and 20 mg (10 mg twice a day or 20 mg daily). Mode of administration is oral. Two more additional dose levels may be added depending on the safety and efficacy profile observed in the first 3 dose levels. Maximum daily dose will not exceed 30 mg. All randomised subjects are planned to receive 6 months of treatment.

In Stage 2, it is intended that a rivaroxaban once daily dose, twice daily dose or both will be selected for comparison to placebo. The dosage will be dependent upon the maximum tolerable dose for individual patient that was discovered during the dose escalation stage. Treatment will also be for 6 months.

Outcomes
Primary outcome [1] 3179 0
The number of patients with recent ACS taking rivaroxaban with background antiplatelet therapy who experience protocol-defined clinically significant bleeding (assessed by clinical assessment and optionally imaging procedures or laboratory tests as appropriate).
Timepoint: Day 1 to Day 210
Timepoint [1] 3179 0
The analysis of the outcome will be through to 6 months. The events will be collated as they occur over the 6 months.
Secondary outcome [1] 5303 0
The number of patients who experience death (all cause), MI, (or reMI), stroke, or ischemia requiring revascularization (assessed by clinical assessment and optionally imaging procedures or laboratory tests as appropriate).
Timepoint: Day 1 to Day 210
Timepoint [1] 5303 0
The analysis of the outcome will be through to 6 months. The events will be collated as they occur over the 6 months.

Eligibility

Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The packaging and dosage will be such that the different treatment groups will appear identical. An interactive voice response system (IVRS) will be used to accomplish a blind allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated random code.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
This is a double blind trial, meaning that the subjects receiving the treatment and all the researchers are blinded to the treatments.
