A Study to Assess the Reversal of the Anticoagulant Effects of Milvexian by 4-Factor Prothrombin Complex Concentrate (4F-PCC) (Part 1) and Recombinant Human Factor VIIa (rFVIIa) (Part 2) in Healthy Participants

The primary purpose of this study is to evaluate the reversal of the anticoagulant effects of milvexian by 4-Factor Prothrombin Complex Concentrate (4F-PCC) and Recombinant Human Factor VIIa (rFVIIa) in healthy participants as measured by changes from baselines of the coagulation testing parameters (activated partial thromboplastin time [aPTT] and thrombin generation assay [TGA]).

Inclusion criteria

  • Participants must be healthy on the basis of medical history, physical examination, vital signs, electrocardiogram (ECG), and laboratory test results, including serum chemistry, lipid profiles (low-density lipoprotein [LDL], high-density lipoprotein [HDL], apolipoprotein B and lipoprotein a), levels of protein C, protein S and antithrombin, fibrinogen, factors VIIIc, IXc, Xc, XIc and blood coagulation (activated partial thromboplastin time [aPTT], prothrombin time [PT]) measured at local laboratory, hematology and urinalysis performed at screening. If abnormalities or deviations from normal are observed, they must be of no clinical significance in the opinion of the investigator
  • Before randomization, a woman must either be: Not of childbearing potential defined as: Postmenopausal-A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level greater than (>) 40 International Units Per Liter (IU/L) or milli-international units per milliliter (mIU/mL) in the postmenopausal range may be used to confirm a postmenopausal state in women, however, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient; Permanently sterile- Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
