efanesoctocog alfa · 5 trials · 3 indications
The number of participants with the occurrence of inhibitor development (neuatralizing antibodies detected against factor VIII \[FVIII\]) as determined via the Nijmegen modified Bethesda assay.
Inhibitor development was defined as an inhibitor result of greater than or equal to (\>=0.6) Bethesda units (BU/mL) that was confirmed by a second test result from a separate sample, drawn 2 to 4 weeks following the date when the original sample was drawn. Both tests must have been performed by the central laboratory using the Nijmegen modified Bethesda assay.
ABR is annualized number of treated bleeding episodes (BE) per participant per year. Treated Bleeding episode: any occurrence of hemorrhage that required administration of BIVV001. It started from 1st sign of bleed and ended no more than 72 hours after last injection to treat bleeding episode, any subsequent bleeding at same location/injections administered less than or equal to (\<=) 72 hours apart from previous injection were considered same bleeding episode. ABR=number of treated BE during efficacy period (EP)/number of days during EP\*365.25. EP reflects the sum of all intervals of time during which participants were treated with BIVV001 according to the study arms and treatment regimens. This outcome measure (OM) presents estimated results (i.e., results estimated by fitting negative binomial \[NB\] regression model on data collected during EP).

| Arm | Type | Description |
|---|---|---|
| Arm A: Previously treated in BIVV001 study | EXPERIMENTAL | This arm includes participants who have completed study EFC16293 or study EFC16295, participants who have completed Arm B or Arm C of this study (LTS16294) and roll over into Arm A, and participants who have completed any other potential BIVV001 study. Participants in this arm will continue receiving BIVV001 prophylaxis treatment once weekly (QW) for a total of 100 exposure days (EDs) cumulative from the parent study and this study. Participants will have the opportunity to continue in this study for up to 4 years, unless BIVV001 is commercially available in their applicable participating country. |
| Arm B: Newly initiated (China Only) in BIVV001 | EXPERIMENTAL | This arm includes Chinese participants of any age who will be newly initiated on BIVV001 prophylaxis treatment once-weekly (QW) for 52 weeks. After 52 weeks of treatment in this arm B, participants will be able to roll over into arm A. |
| Arm C: Newly initiated in BIVV001 with planned major surgery | EXPERIMENTAL | This arm includes participants of any age who will be newly initiated on BIVV001 prophylaxis treatment once-weekly (QW) and will undergo planned major surgery after at least 6 initial EDs with BIVV001, and within 26 weeks from Day 1. After 52 weeks of treatment in arm C, participants will be able to roll into arm A. |
| BIVV001: Participants aged <6 Years | EXPERIMENTAL | Participants aged less than (\<) 6 years received BIVV001 at a dose of 50 international units per kilogram (IU/kg) intravenous (IV) injection once-weekly (QW) prophylaxis for 52 weeks. |
| BIVV001: Participants aged 6 to <12 Years | EXPERIMENTAL | Participants aged 6 to \<12 years received BIVV001 at a dose of 50 IU/kg IV injection QW prophylaxis for 52 weeks. |
| Arm A: Prophylaxis | EXPERIMENTAL | Participants who were on a prophylaxis treatment with a FVIII product prior to study EFC16293 including participants who rolled over from study OBS16221, received BIVV001 50 international units per kilogram (IU/kg) intravenous (IV) injection once-weekly (QW) for 52 weeks in the current study. Study OBS16221 participants with 6 months historical data on prophylaxis treatment with a marketed FVIII product prior to enrollment were analyzed as a subgroup (named as: Arm A: Historical Prophylaxis \[OBS16221\]) in the outcome measure analysis. |
| Arm B: On-Demand Then Prophylaxis | EXPERIMENTAL | Participants who were on an on-demand treatment regimen with a FVIII product prior to study EFC16293, including participants who rolled over from study OBS16221, received BIVV001 50 IU/kg IV injection as an on-demand treatment (as needed for the treatment of bleeding episodes) from Week 1 to Week 26 in current study. At Week 26, participants in Arm B were switched to prophylaxis treatment, and received BIVV001 50 IU/kg, IV injection QW until Week 52. |
| efanesoctocog alfa (BIVV001) | EXPERIMENTAL | Each participant will be sequentially dosed with three single intravenous (IV) doses of first rFVIII (Advate®), second Polyethylene Glycol (PEG)-rFVIII (Adynovi® or Adynovate®), and lastly, BIVV001 |

Efanesoctocog alfa is an investigational therapy being studied for hemophilia A, factor VIII deficiency, and von Willebrand's disease (VWD). It is a recombinant coagulation factor VIII Fc-von Willebrand factor-XTEN fusion protein under development by Sanofi (SNY) for hematology indications.
Efanesoctocog alfa targets factor VIII, a protein essential for blood clotting. It is designed to replace or supplement deficient factor VIII activity in patients with bleeding disorders such as hemophilia A.
Efanesoctocog alfa is being developed by Sanofi, a global biopharmaceutical company traded under the ticker SNY. The drug is also known as BIVV001.
Efanesoctocog alfa is in Phase 3 clinical development for hemophilia A and factor VIII deficiency. It is also being studied in earlier-phase trials for von Willebrand's disease. The drug is investigational and not yet approved.
Efanesoctocog alfa has been studied in several trials, including NCT04161495, a completed Phase 3 study in severe hemophilia A, and NCT04644575, an active Phase 3 long-term safety study in hemophilia A. Additional completed Phase 1 trials include NCT04770935 in von Willebrand's disease and NCT05042440 in hemophilia A.
Yes, efanesoctocog alfa is also known as BIVV001. Both names refer to the same recombinant coagulation factor VIII Fc-von Willebrand factor-XTEN fusion protein being developed by Sanofi.
