New shot could tame rare bleeding disorder
NCT ID NCT07347249
First seen Jun 25, 2026 · Last updated Jul 23, 2026 · Updated 4 times
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.

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.
