Part B-Response to treatment of bleeds. |
Participants or caregivers were asked to assess the response to treatment of bleeds as excellent, good, moderate or poor. Percentage of bleeds per assessment was summarized and reported. |
the duration of study participation, 6 months. |
|
Other |
Number of Participants With Adverse Events (AEs) and Serious Adverse Events. (SAEs) as a Measure of Safety and Tolerability |
An AE is any untoward medical occurrence that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the definition. |
the duration of study participation, 6 months. |
|
Primary |
Part A - score of bleeding symptoms and Vital signs. |
Response to treatment with rFVIIIFc for bleeding episodes, using the 4-point bleeding response scale. |
For the duration of study participation, 6 months. |
|
Primary |
Part B- Annualized Bleeding Rates(ABR). |
Annualized bleeding rate = (number of bleeding episodes during the efficacy, period/total number of days during the efficacy period)*365.25. The efficacy period begins with the first prophylactic dose of FRSW107 and ends with the last dose (for prophylaxis or a bleed). Surgery/rehabilitation periods and PK evaluation periods are not included in the efficacy period. A bleeding episode started from the first sign of a bleed and ended no more than 72 hours after the last treatment for the bleed, within which any symptoms of bleeding at the same location or injections less than or equal to 72 hours apart were considered the same bleeding episode. Any injection to treat the bleeding episode taken more than 72 hours after the preceding one was considered the first injection to treat a new bleeding episode at the same location. Any bleeding at a different location was considered a separate bleeding episode, regardless of time from last injection. |
For the duration of study participation, 6 months. |
|
Primary |
Part B-Number of target joints. |
The joint with =3 times of spontaneous bleeding in 6 consecutive months is the target joint, while the joint with < 2 times of bleeding in 12 consecutive months is no longer the target joint. |
For the duration of study participation, 6 months. |
|
Secondary |
Part A-rFVIIIFc incremental recovery (IR). |
Incremental recovery of Factor VIII (FVIII) within 1 hour after end of infusions was determined and mean recovery values were reported. |
For the duration of study participation, 6 months. |
|
Secondary |
Part A -Total Dose Required for Resolution of a Bleeding Episode. |
The total dose required to resolve a bleeding episode per participant, based on the efficacy period. The efficacy period begins with the first dose and ends with the last dose (for a bleed). For 'Per bleeding episode' values, for each bleeding episode, the total dose is the sum of the doses (IU/kg) administered across all injections given to treat that bleeding episode. For 'Per participant' values, the total dose (IU/kg) used to resolve each bleed is averaged across all bleeding episodes per participant.Quality of life assessment. |
For the duration of study participation, 6 months. |
|
Secondary |
Part A -Number of injections required to resolve a bleeding episode. |
The number of injections required to resolve a bleeding episode per participant, based on the efficacy period. The efficacy period begins with the first dose and ends with the last dose (for a bleed). All injections given from the initial sign of a bleed, until the last date/time within the bleed window are counted. The resolution of a bleed is defined as no sign of bleeding following injection for the bleed. For 'Per participant' values, the number of injections required to resolve each bleed is averaged across all bleeding episodes per participant. |
For the duration of study participation, 6 months. |
|
Secondary |
Part A -Quality of life assessment. |
Quality of life assessment by Haemophilia Joint Health Score(HJHS). |
For the duration of study participation, 6 months. |
|
Secondary |
Part B -Number of injections required to resolve a bleeding episode. |
The number of injections required to resolve a bleeding episode per participant, based on the efficacy period. The efficacy period begins with the first prophylactic dose and ends with the last dose (for prophylaxis or a bleed). All injections given from the initial sign of a bleed, until the last date/time within the bleed window are counted. The resolution of a bleed is defined as no sign of bleeding following injection for the bleed. For 'Per participant' values, the number of injections required to resolve each bleed is averaged across all bleeding episodes per participant. |
For the duration of study participation, 6 months. |

Secondary |
Part B -Quality of life assessment. |
Quality of life assessment by Haemophilia Joint Health Score(HJHS). |
For the duration of study participation, 6 months. |

Secondary |
Part B -Number of participants with inhibitor development |
Number of participants who developed a positive FVIII inhibitor level (=0.6 Bethesda unit [BU]) during the study was summarized and classified as participants developing low titer inhibitor (i.e. = 5.0 BU) and participants developing high titer inhibitor (i.e. > 5.0 BU). |
