An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship with study treatment. TEAEs=AEs that started during the effective duration of treatment regardless of whether a similar event existed at baseline. Grades of AEs were defined by National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) version 5.0. Grade 1=asymptomatic/mild symptoms, clinical or diagnostic observations only, intervention not indicated;Grade 2=minimal, local or noninvasive intervention indicated, limiting age-appropriate instrumental activity of daily living (ADL);Grade 3=severe or medically significant but not immediately life-threatening, hospitalization of prolongation of hospitalization indicated; disabling limiting self-care ADL;Grade 4=events with life-threatening consequences, urgent intervention indicated;Grade 5= death related to AE.Treatment-related TEAEs were determined by investigator.

Laboratory assessments included chemistry, hematology, Prothrombin Time/International Normalized Ratio (PT/INR), Activated Partial Thromboplastin Time (APTT), urinalysis, fibrinogen, Antithrombin III (ATIII) activity, and Cardiac Troponin I (cTnI). Laboratory test abnormalities reported by at least 1 participant are reported in this outcome measure. ULN = upper limit of normal.

PT is one of the laboratory tests to evaluate the ability of blood clotting. The INR is derived from PT which is calculated as a ratio of a participant's PT to a control PT standardized for the potency of the thromboplastin reagent developed by the World Health Organization (WHO) using the following formula: INR = Participant PT / Control PT. Blood samples were obtained to evaluate PT/INR.

The APTT is a screening test that helps evaluate a person's ability to appropriately form blood clots. It measures the number of seconds it takes for a clot to form in a sample of blood after substances (reagents) are added. Blood samples were obtained to evaluate APTT.

Fibrinogen is a protein, specifically a clotting factor (factor I), that is essential for proper blood clot formation. Blood samples were obtained to evaluate the amount of fibrinogen.

ATIII is a nonvitamin K-dependent protease that inhibits coagulation by lysing thrombin and factor Xa. The antithrombin activity test measures how well the protein inhibits thrombin, with a reference range of 75% - 125%. Blood samples were obtained to evaluate ATIII activity.

cTnI is one of the cardiac regulatory proteins that control the calcium mediated interaction between actin and myosin, and is considered a specific marker for cardiac damage. Blood samples were obtained to evaluate the amount of cTnI.

Vital signs measurements included blood pressure (BP), pulse rate, respiratory rate and oral temperature. Categorical classes for vital signs of potential clinical concern included: (1) systolic BP - minimum (min) value \<90 mmHg, maximum (max) decrease/increase from baseline \>=30 mmHg; (2) diastolic BP - min value \<50 mmHg, max decrease/increase from baseline \>=20 mmHg; (3) supine pulse rate - min \<40 beat per minute (bpm) or max \>120 bpm; (4) standing pulse rate - min \<40 bpm or max \>140 bpm; (5) oral temperature \> 38.5 celsius degree (°C). BPs were measured in a supine position so standing BPs were not evaluated and not reported.

Respiratory rate measurement was preceded by at least 5 minutes of rest for the participant in a quiet setting without distractions. Respiratory rate was measured in terms of "breaths per minute", and was measured by observing and counting the respirations of the participant for 30 seconds and multiplied by 2.

Single 12-lead ECGs were performed for all participants in a supine position using an ECG machine that automatically calculated heart rate and measured PR, QRS and QT intervals. If a single time point ECG was abnormal, a triplicate ECG was required and obtained approximately 2-4 minutes apart; the average of triplicate ECG measurements collected at pre-dose Day 1 served as each participant's baseline value.

A complete PE included assessments of the head, ears, eyes, nose, mouth, skin, heart and lung examinations, lymph nodes, gastrointestinal, musculoskeletal, and neurological systems. A brief PE included assessments of the general appearance, the respiratory and cardiovascular systems, as well as participant reported symptoms. The full PE planned for Screening may have been performed on Day -1 before dosing at the discretion of the Investigator. If a full PE was done at Screening visit, a brief PE was to be conducted on Day-1. After Day -1, brief examinations based on signs and symptoms may have been performed if clinically indicated at the discretion of the Investigator to assess changes from baseline/previous visits of any ongoing symptoms.

Grades of injection site reactions were defined according to NCI CTCAE version 5.0. Grade 1=Tenderness with or without associated symptoms (eg, warmth, erythema, itching); Grade 2= Pain, lipodystrophy, edema, phlebitis; Grade 3= Ulceration or necrosis, severe tissue damage, operative intervention indicated; Grade 4=Life-threatening consequences, urgent intervention indicated; Grade 5=death. Participants with any grade of injection site reaction are reported in this outcome measure.
