Vacuolization is defined as the presence of more than one vacuole (defined as a clear, round structure in the INL of the retina of at least 30 microns in diameter) compared to baseline in either the left or right eye as evaluated by ocular coherence tomography (OCT).
The time (in days) from study start to the first occurrence of any of the following clinical outcomes was recorded: CV death, MI, stroke, or UCR. A Clinical Endpoints Committee (CEC) reviewed and adjudicated each suspected efficacy endpoint event while blinded to treatment. Participants who did not have any endpoint event until last visit or participants who were lost to follow-up and had no event were censored at the time of last available information (last study visit). If a participant had a fatal event that was not part of a specific endpoint for analysis, they were censored at the time of death. The Kaplan-Meier estimate reports the percentage of participants who experienced CV death, MI, stroke, or UCR within 3 years from randomization.
Time to AV fistula functional maturation (defined as successful cannulation of the AV fistula for six hemodialysis sessions within three weeks).
An AE is any unfavorable and unintended change in the structure, function or chemistry of the body temporally associated with study drug administration, whether or not considered related to the study drug.
An adverse event (AE) is any unfavorable and unintended change in the structure, function, or chemistry of the body temporarily associated with study drug administration, whether or not considered related to study drug. MACE events were defined as nonfatal myocardial infarction (MI), nonfatal stroke, hospitalization due to recurrent ischemia, or urgent coronary revascularization. All MACE events were excluded from this analysis.
Mean of week 8 and week 12 minus week 0 (on log10 scale) then back transforming the log10 difference to obtain percentage change from baseline.
| Arm | Type | Description |
|---|---|---|
| Vorapaxar | EXPERIMENTAL | Participants receive a vorapaxar 2.5 mg tablet administered orally once daily for 1 year |
| Placebo | PLACEBO_COMPARATOR | Participants receive a matching placebo tablet to vorapaxar administered orally once daily for 1 year |
| Vorapaxar intervention | ACTIVE_COMPARATOR | This arm will receive the study drug: Vorapaxar sulfate. The investigators expect to enroll 128 patients. Patients will be assigned to treatment groups with a 1:1 randomization in blocks of 4 at the conclusion of the AV fistula creation. Patients will be stratified based on fistula location (lower arm versus upper arm). |
| Placebo intervention | PLACEBO_COMPARATOR | This arm will receive the matching placebo. The investigators expect to enroll 128 patients. Patients will be assigned to treatment groups with a 1:1 randomization in blocks of 4 at the conclusion of the AV fistula creation. Patients will be stratified based on fistula location (lower arm versus upper arm). |
