Trial Outcomes & Findings for Safety and Efficacy of FVIIa to Prevent Excessive Bleeding in Hemophilia Patients With Inhibitors Undergoing Major Surgery (NCT NCT05695391)

NCT ID: NCT05695391

Last Updated: 2026-07-31

Results Overview

Successfully treated major procedures defined by a good or excellent global hemostatic response, based on an aggregate score from 3 timepoints (intra-operative, 24h post-operative, 120h post-operative), each individual score depending on comparison between actual and preliminary-communicated expected blood loss and transfusions for a similar patient without bleeding disorder undergoing the same surgical procedure, but also on the use or not of IMP extra-doses or of rescue therapy.

Participant Flow

Male patients, aged ≥12 years to ≤65 years, with hemophilia A or B with positive inhibitor test BU ≥5 (current or past if not further successfully treated by ITI), or a condition precluding the use of FVIII or FIX products to treat/prevent bleeding, and scheduled to undergo an elective major surgery, were to be enrolled. Major surgeries were those that usually required ≥5 days of factor replacement in this population and typically involved entry into a body cavity or similarly complex procedures

During the screening period, the surgeons had to communicate at least 3 working days before the date of the planned surgery, its expected characteristics including blood loss and transfusion predictions for approval by an enrollment committee comprising an expert surgeon competent in the surgery in patients with hemophilia.

PRIMARY outcome

Timeframe: From surgical wound closure until 120 hours after surgical wound closure

Population: Full Analysis Set was planned to be used, comprised of all major procedures conducted from patients enrolled into the study who had received at least one dose of study drug with each patient having one treated major procedure. However, as only two patients were enrolled due to study termination caused by feasibility considerations, no population-based analysis was done. Only individual data were recorded.

Successfully treated major procedures defined by a good or excellent global hemostatic response, based on an aggregate score from 3 timepoints (intra-operative, 24h post-operative, 120h post-operative), each individual score depending on comparison between actual and preliminary-communicated expected blood loss and transfusions for a similar patient without bleeding disorder undergoing the same surgical procedure, but also on the use or not of IMP extra-doses or of rescue therapy.

1/2 • Number of events 1 • Adverse Events (AEs) were to be collected from the time of signing of the informed consent/assent until resolution or until the follow-up call which was 30 ± 2 days after the last dose of EB, or until early termination, whichever came first. As only 2 patients were effectively enrolled in the study, any AE would have a frequency of at least 50%, thus effectively exceeding the frequency threshold above which other adverse events are reported, therefore all AEs are reported.
An AE was defined as any untoward medical occurrence in a patient to whom a medicinal product is administered, regardless of the cause. Unfavorable and unintended signs including clinically significant abnormal laboratory findings, but also symptoms, diseases, whether new or exacerbated, temporally associated with the use of the study treatment, were regarded as AEs, whether or not related to the study drug, and looked for at each visit.
