• A positive urine drug test at screening and/or admission

• Screening supine BP ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic)

• Baseline 12 lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results

• Participants with ANY of the following abnormalities in clinical laboratory tests at screening:

  • AST or ALT level ≥1.5 × ULN;
  • Total bilirubin level ≥1.5 × ULN.

• An estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73m2 based on the CKD-EPI equation.

• Resistance to activated protein C (or Factor V Leiden mutation), prothrombin 20210 mutation, antithrombin III deficiency, protein C deficiency, or protein S deficiency.

• Presence of Lupus anticoagulant anti-cardiolipin antibodies (IgG, IgM or IgA)

• High sensitivity C-reactive protein (hsCRP) above the upper limits of normal

• Abnormal hematology values as defined by the following laboratory tests at Screening and/or admission:

  • Platelet count <100,000/uL
  • Hemoglobin level <10 g/dL

• A positive COVID-19 test.

• History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening

• Use of tobacco/nicotine containing products in excess of the equivalent of 5 cigarettes/day

• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.

• Unwilling or unable to comply with the criteria in the Lifestyle Considerations section of the protocol

• Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family members
