Participant Flow

Participants took part in the study at various investigative sites globally from 12 November 2015 to 29 October 2024.

Previously untreated patients (PUPs) \<6 years with severe hemophilia A (Factor VIII \[FVIII\] \<1%) were treated with BAX 855 in Part A of this study for at least 100 exposure days (EDs) or until they had developed a confirmed FVIII inhibitor. Then, participants who developed high or low titer FVIII inhibitors entered Part B. In Part B they underwent immune tolerance induction (ITI) with BAX 855.

All Participants
PUPs \< 6 years of age with severe hemophilia A (FVIII \< 1%) and \< 3 EDs to ADVATE, BAX 855 or plasma transfusion were enrolled in a single arm group. Part A (Main Study): Participants age \<3 years - who had not experienced two joint bleeds received on-demand treatment of 10-80 international units per kilogram (IU/kg) intravenously (IV) depending on the severity of the bleeding episode; and - who experienced maximum of two joint bleeds received prophylaxis treatment with dose of 25-80 IU/kg of BAX 855 IV (based on investigator discretion) once weekly for up to 100 EDs. Part B (ITI Portion): Participants who met the pre-defined Part B treatment criteria entered Part B of the study for ITI. Participants either received prophylaxis treatment of BAX 855 low dose 50 IU/kg IV, three times a week or high dose 100-200 IU/kg IV, daily at the discretion of the investigator according to the institution's standard of care.

SECONDARY outcome

Timeframe: Throughout Part A and Part B of the study, approximately 9 years

Population: The SAS included all participants in the enrolled population with at least one BAX 855 infusion for Part A of the study and the IAS included all participants who received at least one FVIII inhibitor treatment with BAX 855 during the study after the date that participant moved to FVIII inhibitor treatment for Part B of the study.

An AE is defined as any untoward medical occurrence in a participant administered an investigational product (IP) that does not necessarily have a causal relationship with the treatment. A SAE is any untoward clinical manifestation of signs, symptoms or outcomes (whether considered related to investigational product or not and at any dose) which results in death, is life-threatening, requires inpatient hospitalization, prolongation of hospitalization, is an important medical event. Number of participants with AEs and SAEs in both Part A and Part B were assessed. A participant that received on-demand treatment first and then moved to prophylaxis treatment was counted for both on-demand and prophylaxis regimens. A participant that started with prophylaxis treatment was counted only for the prophylaxis regimen even if the participant received on-demand treatment while on the prophylaxis regimen.

ABR was assessed based upon each individual bleeding episode. A bleeding episode was defined as subjective (pain consistent with a joint bleed) or objective evidence of bleeding which may or may not require treatment with FVIII. Bleeding occurring at multiple locations related to the same injury (example, knee and ankle bleed following a fall) was counted as a single bleeding episode. Mean total annualized bleed rate is reported. A participant that received on-demand treatment first and then moved to prophylaxis treatment was counted for both on-demand and prophylaxis regimens. A participant that started with prophylaxis treatment was counted only for the prophylaxis regimen even if the participant received on-demand treatment while on the prophylaxis regimen.

SECONDARY outcome

Timeframe: Throughout Part A of the study, approximately 5 years

Population: The SAS included all participants in the enrolled population with at least one BAX 855 infusion.

A bleeding episode is defined as subjective (pain consistent with a joint bleed) or objective evidence of bleeding which may or may not require treatment with FVIII. The number of BAX 855 infusions needed for each bleeding episode was determined by the participant, caregiver, clinician treating the participant, and is based upon the participant's response to treatment, using the Efficacy Rating Scale for Treatment of Bleeding Episodes. Number of bleeding episodes are categorized by number of infusions required to treat the bleeding episodes. A participant that received on-demand treatment first and then moved to prophylaxis treatment was counted for both on-demand and prophylaxis regimens. A participant that started with prophylaxis treatment was counted only for the prophylaxis regimen even if the participant received on-demand treatment while on the prophylaxis regimen.

Timeframe: Surgery Day 0 up to postoperative Day 14 or discharge (whichever occurs first)

Population: The IPRAS included all participants who were treated with BAX 855 for one or more surgeries or invasive procedures in the context of the study. Number analyzed are the participants who experienced blood loss.

The intraoperative blood loss was measured by determining the volume of blood and fluid removal through suction into the collection container (waste box and/or cell saver) and the estimated blood loss into swabs and towels during the procedure, per the anesthesiologist's record. Post-operatively, blood loss was determined by the drainage volume collected, which mainly consisted of drainage fluid via vacuum or gravity drain, as applicable. The assessment was done for the intra-operative time period (prior to discharge from recovery room) and for the post-operative time period (from completion of the procedure until approximately 24 hours post-surgery).

Timeframe: Baseline up to Study Completion (Up to 5 years in Part A and up to 3.5 years in Part B)

Population: The Pharmacokinetic (PK) analysis set (PKAS) included all participants in the SAS who had at least one post-dose measurement of FVIII activity without protocol deviations and/or events with potential to affect concentration (FVIII activity levels). Number analyzed is the number of participants with data available for analyses.

BAX 855 was administered in participants for the determination of FVIII IR at study site at baseline \& every study visit other than study visits at 5 EDs, 15 EDs \& 30 EDs. FVIII assays were done using following methods:1-stage clotting FVIII activity \& FVIII chromogenic activity. Data is reported for each of these methods as categories per visit. Study Completion assessment was conducted at end of the Main Study \& again at end of the ITI portion. Thus, more number of participants were analyzed at study completion visit than those who actually completed the overall study. IR is reported as a ratio of (IU/deciliter \[dL\])/(IU/kg), calculated as: IR = (Cmax- (C pre-infusion)) / (IU/kg), where C=concentration. Visits and their approximate time in weeks after baseline visit for individual participants: Visit 1 (Week 5), Visit 2 (Week 10), Visit 3 (Week 15), Visit 4 (Week 20), Visit 5 (Week 30), Visit 6 (Week 40), Visit 7 (Week 55), Visit 8 (Week 75) \& Study Completion Visit (Weeks 100-110).
