Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prevention and Treatment Group (PPX group)

Subjects received single and multiple doses of 50 IU/kg FRSW117 at first administration of V1 (D1), V4 (18w), and V7 (50w), and PK samples were collected until 168 h post-administration, respectively.

During prophylaxis, FRSW117 is used for breakthrough therapy if the subject has a breakthrough bleeding event (i.e., a bleeding event during prophylaxis) that requires treatment.

Group Type EXPERIMENTAL

FRSW117

Intervention Type DRUG

once a week, 50 weeks and as needed

On Demand/Preventive Treatment Group (On Demand /PPX Group)

The appropriate dose and frequency of administration of FRSW117 is recommended until bleeding events are controlled or returned to pre-bleeding activity.

Group Type EXPERIMENTAL

FRSW117

Intervention Type DRUG

once a week, 50 weeks and as needed

Perioperative management

Patients in the PPX and on demand /PPX groups will be allowed to undergo surgery (both major and minor) during the main trial period (prior to 50w), while FRSW117 will be administered perioperatively

Group Type EXPERIMENTAL

FRSW117

Intervention Type DRUG
