Outcome Measures

Primary Outcomes (1)

  • Incidence of treatment-emergent adverse events (TEAEs)

    Day 1 through Day 57

Secondary Outcomes (10)

  • Pharmacokinetic Parameter: Maximum observed plasma concentration (Cmax) of sutacimig

    Day 1 through Day 57

  • Pharmacokinetic Parameter: Time to reach maximum observed plasma concentration (Tmax)

    Baseline through Day 57

  • Pharmacokinetic Parameter: Area under the plasma concentration-time curve from time zero to last quantifiable concentration (AUClast)

    Day 1 through Day 57

  • Pharmacokinetic Parameter: Area under the curve from time zero to extrapolated infinite time (AUCinf)

    Day 1 through Day 57

  • Pharmacokinetic Parameter: Terminal elimination phase half-life (T1/2)

    Day 1 through Day 57

  • +5 more secondary outcomes

Study Arms (2)

Interventions

Sutacimig is a subcutaneously administered, bispecific antibody being developed as a prophylactic treatment option for congenital bleeding disorders.

Participants with a FVII(a) level of < 10%

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18 to 60 years, inclusive, at the time of signing informed consent.
  • Diagnosis of FVIID defined by Factor VII:C activity \< 10% documented on ≥ 2 different laboratory measurements by local laboratory assessment.
  • Severe bleeding history characterized by history of a major bleeding event and/or receipt of recombinant activated FVII or fresh frozen plasma as treatment for bleeding or a severe clinical bleeding history as defined by the Investigator.
  • Has the ability to provide informed consent to participate in the trial.

You may not qualify if:

  • Presence of known inhibitors to FVII or FVIIa
  • History of clinically significant hypersensitivity associated with monoclonal antibody therapies.
  • History of venous or arterial thrombosis or thromboembolic disease, with the exception of catheter-associated superficial vein thrombosis.
  • Known thrombophilia risk by the following criteria: Homozygous Factor V Leiden (FVL), compound heterozygous FVL/Prothrombin gene mutation, antithrombin \<50%, congenital protein C, and protein S deficiency with levels \<50%.
  • Clinically significant comorbidity that may interfere with study participation.
  • Use of concomitant therapy not permitted during the study (i.e., other platelet inhibitors, desmopressin, fibrinolysis inhibitors, except if used as local treatment \[e.g., for oral bleeds\])
  • Female participants who are pregnant or breastfeeding.
