Evaluate the Effects of Renal Impairment on the Pharmacokinetics and Pharmacodynamics

The study is a multicenter, Phase 1, open-label, sequential, adaptive, single dose, PK/PD study in subjects with moderate and severe RI and healthy volunteers (HV).

Because MT1002 for Injection is being developed for use as an anticoagulant and antiplatelet in patients with ACS and in patients undergoing PCI, these patients may have impaired RF, and it is important to evaluate whether exposure-response or exposure-safety relationship will be altered in RI. In addition, according to the FDA recommendations, a dedicated RI study including severe RI must be conducted.

The study will be performed in 2 sequences, with interim safety, tolerability, PK, and PD review between both sequences:

    1. 30 to 59 mL/min (Moderate RI, Group 1);
    2. \< 30 mL/min (Severe RI, Group 3) not requiring dialysis.

Exclusion Criteria:

1. Positive pregnancy test at screening or Baseline (Day -1), lactating female subject, or planned to become pregnant during the study.
2. Positive urine cotinine test, alcohol breath test, or drug test, unless for RI patients only, the subject uses any of these drugs as prescriptions that is approved by the PI.
3. Positive serology test results for HBsAg, HCV antibody, or HIV antigen and antibody at screening, or active infections.
4. History of significant allergic reactions (e.g., anaphylactic reaction, hypersensitivity, angioedema) to any drug, to mannitol, or to any excipient in the formulation of MT1002 for Injection.
5. Any acute illness within 14 days prior to the screening visit.
6. Clinically significant history of congenital or acquired bleeding disorders, thrombocytopenia or functional platelet defects, gastrointestinal disease with or without active ulceration, active cancer, vascular retinopathy, bronchiectasis, pulmonary cavitation, or pulmonary bleeding.
7. History of major bleeding, trauma, surgical procedure of any type, or vaginal delivery within 6 months prior to screening.
8. Personal or family history of clotting or coagulation disorder or abnormality, thrombovascular disease or any hematologic disorder involving platelets or clotting abnormalities or any condition requiring treatment with transfusions, anticoagulants or platelet inhibitors.
9. History of peptic ulcer, gastrointestinal bleeding (including hematemesis, melena, rectal bleeding) or bleeding from hemorrhoids within 6 months prior to screening.
10. History of easy bruising, excessive bleeding from an injury or after surgery or dental work, minor bleeding episodes such as epistaxis, rectal or hemorrhoidal bleeding (spots of blood on toilet paper), blood in urine or stool or history of black stools, or gingival bleeding within 3 months prior to screening.
11. Females with a history of dysfunctional uterine bleeding, including history of menorrhagia (heavy or long menstrual bleeding), metrorrhagia or polymenorrhea.
12. PT or aPTT \> upper limit of normal at Screening or Day -1.
13. Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding volume drawn at screening or menses) of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the dosing.

    Exclusion Criteria for Subjects with Normal RF (Control Group):
14. Clinically significant abnormal laboratory test results (e.g. alanine aminotransferase (ALT), alkaline phosphatase (AP), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) or bilirubin) as judged by the Investigator or designee at Screening.
15. Clinically significant electrolyte abnormalities (e.g., hypokalemia or hypomagnesemia), congestive heart failure, or other currently prescribed medicinal products that lead to QT prolongation.
16. Administration of any blood product or anticoagulant within 1 month prior to screening.
17. Clinically significant ECG abnormalities (that could have jeopardized the subject's safety to participate in this study or a screening 12-lead ECG that demonstrated any one of the following: HR \> 100 beats per minute (bpm), QRS \> 120 msec, QTcF ≥450 ms in males or ≥470 ms in females, or PR \> 220 msec, or vital signs abnormalities (systolic BP lower than 90 or over 140 mmHg, diastolic BP lower than 50 or over 90 mmHg, HR less than 50 or over 100 bpm, or RR less than 10 or over 22 bpm) at screening.
