A Clinical Study to Assess the Safety and Efficacy of Sutacimig in Participants With Congenital Factor VII Deficiency

Open-label study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of a single dose of sutacimig monotherapy in participants with congenital FVII deficiency (FVIID).

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The objective is to administer a single dose of sutacimig and to evaluate safety, pharmacokinetics, and pharmacodynamics. Two cohorts may be evaluated. Cohort A is defined by participants with a FVII(a) level of < 10%. Cohort B is defined by participants with a FVII(a) level of ≥10%.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Description

Inclusion Criteria:

  1. Age 18 to 60 years, inclusive, at the time of signing informed consent.
  2. Diagnosis of FVIID defined by Factor VII:C activity < 10% documented on ≥ 2 different laboratory measurements by local laboratory assessment.
  3. 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.
  4. Has the ability to provide informed consent to participate in the trial.

Exclusion Criteria:

  1. Presence of known inhibitors to FVII or FVIIa
  2. History of clinically significant hypersensitivity associated with monoclonal antibody therapies.
  3. History of venous or arterial thrombosis or thromboembolic disease, with the exception of catheter-associated superficial vein thrombosis.
  4. 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%.
  5. Clinically significant comorbidity that may interfere with study participation.
  6. 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])
  7. Female participants who are pregnant or breastfeeding.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Incidence of treatment-emergent adverse events (TEAEs)
Time Frame: Day 1 through Day 57
Day 1 through Day 57

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
