This study evaluates the safety and efficacy of AB002 (E-WE thrombin) in patients with end stage renal disease on chronic hemodialysis. Two dose levels will be evaluated in two cohorts. Within each cohort the patients will be randomized to receive either AB002 (E-WE thrombin) or placebo (at a ratio of 2:1 active: placebo).

| Measure | Description | Time Frame |
|---|---|---|
| The Number of Subjects With Treatment-emergent Adverse Events (TEAEs) Related to Treatment Will be Summarized Using Frequency Counts (Safety and Tolerability) | TEAEs will be determined by physical examination that will include assessment of skin, head, ears, eyes, nose, throat, respiratory system, cardiovascular system, gastrointestinal system, neurological condition, blood and lymphatic systems, and the musculoskeletal system. | 22 days |
| The Number of TEAEs Related to Treatment Will be Summarized Using Frequency Counts (Safety and Tolerability). | TEAEs will be determined by physical examination that will include assessment of skin, head, ears, eyes, nose, throat, respiratory system, cardiovascular system, gastrointestinal system, neurological condition, blood and lymphatic systems, and the musculoskeletal system. | 22 days |
| The Number of Subjects With Bleeding at the Hemodialysis (HD) Vascular Access Site (Safety and Tolerability) | The number of patients in which clinically relevant and non-major bleeding events occurred from the vascular access site. Bleeding from the access site was assessed immediately following decannulation. Pressure was placed on the access site for 10 min. After 10 minutes, the access site was checked for bleeding. If still bleeding, pressure was applied for another 5 minutes and checked again. This was repeated until hemostasis was achieved and the time to hemostasis was recorded. A time greater than 10 min was considered a non-major bleeding event. | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |
| The Number of Subjects With Abnormal Electrocardiogram That is Related to Treatment Will be Summarized Using Frequency Counts (Safety and Tolerability). | 12-lead electrocardiogram measurement. Abnormal electrocardiogram was determined by the study PI. The result was determined to be treatment related if the abnormal electrocardiogram occurred post-treatment and not pre-treatment. Data from the specified time points (Study Day 1 (0.5h post-dose) and Study Day 3) were combined by adding the number of participants on each Study Day that showed an abnormal electrocardiogram compared to pre-treatment (Study Day -8). |
| Measure | Description | Time Frame |

| Hemodialysis Efficiency as Measured by Frequency of Clotting on the Dialysis Filters and Circuit (Pharmacodynamic Outcome). | Assessment of thrombus accumulation in the dialyzer cartridge measured by visual inspection. Assessment of thrombus accumulation in the dialysis filter measured by visual inspection. A score ranging from 1-6 is determined by someone blinded to treatment by the Visual Score Assessment of Clotting in the Hemodialysis Circuit scale: 1- no clotting/clean dialyzer or few blood streaks affecting less than 5% of the fibers seen at the surface of the dialyzer, 2- blood streaks affecting more than 5% but less than 25% of the fibers seen at the surface of the dialyzer, 3- blood streaks affecting more than 25% but less than 50% of the fibers seen at the surface of the dialyzer, 4- blood streaks affecting more than 50% but less than 75% of the fibers seen at the surface of the dialyzer, 5- blood streaks affecting more than 75% of the fibers seen at the surface of the dialyzer, and 6- complete occlusion, coagulated filter (treatment cannot continue without replacement of dialyzer). |

| Secondary | Hemodialysis Efficiency as Measured by Frequency of Clotting on the Dialysis Filters and Circuit (Pharmacodynamic Outcome). | Assessment of thrombus accumulation in the dialyzer cartridge measured by visual inspection. Assessment of thrombus accumulation in the dialysis filter measured by visual inspection. A score ranging from 1-6 is determined by someone blinded to treatment by the Visual Score Assessment of Clotting in the Hemodialysis Circuit scale: 1- no clotting/clean dialyzer or few blood streaks affecting less than 5% of the fibers seen at the surface of the dialyzer, 2- blood streaks affecting more than 5% but less than 25% of the fibers seen at the surface of the dialyzer, 3- blood streaks affecting more than 25% but less than 50% of the fibers seen at the surface of the dialyzer, 4- blood streaks affecting more than 50% but less than 75% of the fibers seen at the surface of the dialyzer, 5- blood streaks affecting more than 75% of the fibers seen at the surface of the dialyzer, and 6- complete occlusion, coagulated filter (treatment cannot continue without replacement of dialyzer). | Posted | Geometric Mean | Standard Error | average visual score of dialyzer filter | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |

| Secondary | Hemodialysis Efficiency as Measure by the Frequency of Clotting on the Dialysis Circuit: Venous Chamber (Pharmacodynamic Outcome) | Assessment of thrombus accumulation in the dialysis venous chamber measured by visual inspection. A score ranging from 1-7 is determined by someone blinded to treatment using a Visual Score Assessment of Clotting in the Hemodialysis Circuit: 1- no detectable clotting, 2- presence of fibrous ring or minimum clot affecting less than 5% of chamber space, 3- clot formation, affecting more than 5% but less than 25% of chamber space, 4- clot formation, affecting more than 25% but less than 50% of chamber space, 5- clot formation, affecting more than 50% but less than 75% of chamber space, 6- clot formation, affecting more than 75% of chamber space, and 7- Complete occlusion of chamber. | Posted | Geometric Mean | Standard Error | average visual score of venous chamber | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |
|
|
|
| Secondary | Hemodialysis Efficiency as Measured by Blood Urea Nitrogen (BUN) Levels, URR (Pharmacodynamic Outcome). | Assessment of BUN (mg/dL) before and after hemodialysis as urea reduction ratio (URR), %. | In some instances, the pre-and post-dialysis values appeared to be switched and were excluded from the summary statistics or a value was missing or not reportable. | Posted | Geometric Mean | Standard Deviation | Urea reduction ratio (%) | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |
|
|
|
| Secondary | Hemodialysis Efficiency as Measured by Blood Urea Nitrogen (BUN) Levels (Pharmacodynamic Outcome), KtV. | Assessment of BUN (mg/dL) before and after hemodialysis as KtV (mL/min). | In some instances, the pre-and post-dialysis values appeared to be switched and were excluded from the summary statistics or a value was missing or not reportable. | Posted | Geometric Mean | Standard Deviation | KtV (mL/min) | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |
|
|
|
| Secondary | Hemodialysis Efficiency as Measured by Blood Potassium Levels (Pharmacodynamic Outcome). | Assessment of plasma potassium (mmol/L) before and after hemodialysis. The reduction of plasma potassium is reported as fold change (post-hemodialysis plasma potassium/ pre-hemodialysis plasma potassium). | In some instances, the pre-and/or post-dialysis values appeared to be switched and were excluded from the summary statistics or a value was missing or not reportable. | Posted | Geometric Mean | Standard Deviation | fold change plasma potassium | At each hemodialysis session (non-dose days: study day -7, -5, -2, and 3 and dose day: study day 1) |

|
| Secondary | The Effect of a Single Intravenous Dose of E-WE Thrombin on Plasma Activated Protein C-Protein C Inhibitor Complex (APC-PCI) Levels as a Surrogate for Drug Exposure. | Plasma APC-PCI (ng/mL) levels will be determined by ELISA. | In some samples the values were missing or not reportable. | Posted | Geometric Mean | Standard Deviation | ng/mL | Study day 1: (pre-dose, 0.167h, 0.5h, 1h, 2h, 4h, 6h, 24h post-dose) |
|
|
|
| Secondary | The Number of Subjects That Develop Anti-drug Antibodies Will be Summarized by Frequency Counts. | Plasma anti-drug antibodies will be determined by ELISA. | Day 14 sample was not collected from one participant in the 3.0 mcg/kg AB002 group. | Posted | Count of Participants | Participants | Study day 1 pre-dose and study day 14 |
