New hope for rare bleeding disorder: BIVV001 tested in humans
NCT ID NCT04770935
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tested a single injection of a new drug called BIVV001 in 6 adults with severe forms of von Willebrand disease (types 2N and 3). The goal was to see how the drug behaves in the body and whether it is safe. If results are promising, larger studies could follow to see if it helps control bleeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- efanesoctocog alfa (BIVV001)
- What this could lead to
- If successful, this could lead to a new treatment option that helps control bleeding episodes in people with severe von Willebrand disease.
- What could go wrong
- This is a very early, small Phase 1 trial with only 6 participants, so results may not apply to everyone. The drug may not work as hoped or could cause unexpected side effects.

Inclusion criteria : \-- Male and/or female participant, between 18 and 65 years of age, inclusive at the time of informed consent. * The participant has been diagnosed with hereditary type 3 VWD or type 2N VWD as documented in historical medical records OR a documented genotype known to produce VWD type 3 or 2N VWD. * Type 3 VWD participants are included if they have a medical history of at least 25 exposure days to VWF and factor VIII-containing coagulation factor concentrates * Type 2N VWD participants are included if the use of DDAVP is deemed insufficient or contraindicated, as assessed by the Investigator, or if they have required prior use of VWF- and FVIII- containing coagulation factor concentrates. Exclusion criteria: * Hereditary or acquired coagulation disorder other than VWD (including qualitative and quantitative platelet disorders, and thrombocytopenia \< 100,000 cells/uL at Screening) * The participant has a FVIII activity levels \>20 IU/dL, at Screening * History or presence of a VWF inhibitor or clinical suspicion of a VWF inhibitor * History of a positive FVIII inhibitor test, defined as ≥0.6 BU/mL (by Nijmegen modified Bethesda assay) or a clinical suspicion of a FVIII inhibitor * Positive FVIII inhibitor test, defined as ≥0.6 BU/mL, at Screening * History of hypersensitivity or anaphylaxis associated with any FVIII- or VWF- containing product * The participant has received or anticipates receiving systemic immunosuppressive or immunomodulatory treatment within 12 weeks prior to Baseline. * The participant requires the use of acetylsalicylic acid, non-NSAID anti-platelets, and NSAIDs above the maximum dose product * Patients currently on a prophylaxis regimen for the treatment of VWD that, in the Investigator's opinion, would preclude participation in the study due to the possible increased risk of bleeding associated with the requirement to withhold prophylaxis during the study. The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
