This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests a new drug called sutacimig in 18 adults with a rare inherited bleeding disorder (factor VII deficiency). The drug is given as a single shot under the skin to see if it is safe and can help prevent bleeding. The goal is to find a more convenient treatment option for people who currently need frequent infusions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
sutacimig (a bispecific antibody given as a shot under the skin)
What this could lead to
If it works, this could point toward a new preventive treatment to reduce bleeding episodes in people with factor VII deficiency.
What could go wrong
This is a very early, small Phase 2 trial with only 18 people, so results may not apply to everyone. The drug is still experimental, and safety or effectiveness is not yet proven.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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.

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.
