End-stage renal disease (ESRD) maintained on stable outpatient hemodialysis (HD) regimen, using an established (> 3 months) and normally functioning, regular flow, uninfected mature arteriovenous (AV) fistula or AV graft and skin consistent with standard chronic HD access injuries, and HD stability defined as ([K, dialyzer clearance, multiplied by t, time, divided by V, patient's total body water] Kt/V) ≥ 1.2 within 3 months prior to dosing at a healthcare center for > 3 months from dosing. On HD regimen at least 3 times per week for a minimum of 3 hours per dialysis session, using a complication-free well-maintained AV fistula or AV graft, expected and plan to continue this throughout and for at least 3 months beyond the study. Has a Body Mass Index (BMI) ≥ 18 and ≤ 45 kg/m^2, BMI = weight (kg)/height (m)^2. Baseline health is judged to be stable based on medical history, physical examination, vital sign measurements and electrocardiogram (ECG) performed prior to randomization. Liver function test (serum alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) must be equal to or below 1.5X upper limit of normal (ULN) and deemed not clinically significant by both the investigator and the Sponsor. Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies by agreeing to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a woman of childbearing potential (WOCBP) who is not currently pregnant. Also, men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration. Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies in that a female participant is eligible to participate if she is not pregnant or breastfeeding and she is not a WOCBP in that she is a postmenopausal female without menses for at least 1 year OR is a surgically sterile female, post hysterectomy, bilateral salpingectomy, oophorectomy or tubal ligation. Exclusion Criteria: Has a history of any clinically significant concomitant disease or condition (including treatment for such conditions) or diseases whose current condition is considered clinically unstable that, in the opinion of the investigator, could either interfere with the study drug, compromise interpretation of study data, or pose an unacceptable risk. Participants with a remote history of uncomplicated medical events (e.g., uncomplicated kidney stones, as defined as spontaneous passage and no recurrence in the last 5 years, or childhood asthma) may be enrolled in the study at the discretion of the investigator.

Has blood coagulation test (activated partial thromboplastin time [aPTT], prothrombin time [PT]) ≥ 20 % outside of normal range on pretrial (screening), which are considered clinically significant by both the investigator and the sponsor. Any other clinically significant abnormalities in laboratory test results at screening that would, in the opinion of the investigator, increase the participant's risk of participation, jeopardize complete participation in the study, or compromise interpretation of study data. Has a history of deep vein thrombosis or pulmonary embolism. Has a history of vascular access thrombosis within 1 month prior to enrollment. Has a personal or family history of bleeding disorder. Has a history of gastrointestinal (GI) bleeding, duodenal polyps or gastric ulcer in the last 5 years or severe hemorrhoidal bleed in last 3 months.

Participants must have a negative serum or saliva drug screen prior to randomization. Participants with a positive drug screen due to the use of physician prescribed medications (e.g., opioids, benzodiazepines, antidepressants) may be enrolled at the discretion of the investigator. In addition, participants with a positive tetrahydrocannabinol (THC) may be enrolled at the discretion of the investigator if the participants' THC use is under 4 times/month and the participants agree to not use during their study participation. Participants with positive THC on screening may have rechecks performed at the discretion of the investigator to ensure compliance with abstinence from THC use during study participation.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
