This multicenter, open-label study will evaluate the safety, efficacy and pharmacokinetics of prophylactic emicizumab treatment in participants previously treated with episodic or prophylactic bypassing agents. Episodic bypassing agent participants will be randomized in a 2:1 fashion to receive emicizumab prophylaxis (Arm A) versus no prophylaxis (Arm B) and will be stratified across Arms A and B according to the number of bleeds they experienced over the last 24 weeks prior to study entry (less than \[<\] 9 or greater than or equal to \[>/=\] 9 bleeds); Arm B participants will have the opportunity to switch to emicizumab prophylaxis after at least 24 weeks on-study. Prophylactic bypassing agent participants will switch to emicizumab prophylaxis (Arm C) from the start of the trial; enrollment will be extended for 24 weeks after the last participant has enrolled in Arms A or B or until approximately 50 participants have enrolled in Arm C, whichever occurs first. Episodic bypassing agent participants who previously participated in the non-interventional study BH29768 (NCT02476942) who were unable to enroll in Arms A or B, or participants on prophylactic bypassing agents who were unable to enroll in Arm C, prior to their closure will have the opportunity to enroll in Arm D. Like participants in Arms A and C, Arm D participants will receive emicizumab prophylaxis from the start of the trial. All participants will continue to receive episodic bypassing agent therapy to treat breakthrough bleeds, preferably with recombinant activated factor VII (rFVIIa).

Objetivos del Estudio

4 grupos de intervención están designados en este estudio

0% de probabilidad de ser asignado al grupo placebo

Grupos de Tratamiento

Grupo I

Experimental
Participants who were receiving episodic treatment with bypassing agents prior to study entry and were randomized to study Arm A started to receive emicizumab prophylaxis. Emicizumab was administered at a loading dose of 3 milligrams per kilogram (mg/kg) once a week (QW) subcutaneously (SC) for the first 4 weeks followed by a maintenance dose of 1.5 mg/kg emicizumab QW SC up to the end of study. Participants continued to receive bypassing agent therapy to treat any breakthrough bleeds.

Grupo II

Comparador Activo
Participants who were receiving episodic treatment with bypassing agents prior to study entry and were randomized to study Arm B continued with their prior episodic treatment regimen for the first 24 weeks of the study; they did not receive emicizumab prophylaxis during that time. After completing at least 24 weeks on study, participants in Arm B were allowed to switch to emicizumab prophylaxis (as described for Arm A) up to the end of study. Participants continued to receive bypassing agent therapy to treat any breakthrough bleeds.

Grupo III

Experimental
Participants who were receiving prophylactic bypassing agents prior to study entry were enrolled in Arm C to receive prophylactic emicizumab. Emicizumab was administered at a loading dose of 3 mg/kg QW SC for the first 4 weeks followed by a maintenance dose of 1.5 mg/kg emicizumab QW SC up to the end of study. Participants continued to receive bypassing agent therapy to treat any breakthrough bleeds.

Grupo IV

Experimental
Participants who were either: 1) Receiving episodic bypassing agents prior to study entry but were unable to enroll in Arms A or B; or 2) Receiving bypassing agent prophylaxis prior to study entry but were unable to enroll in Arm C, were enrolled in Arm D to receive emicizumab prophylaxis. Emicizumab was administered at a loading dose of 3 mg/kg QW SC for the first 4 weeks followed by a maintenance dose of 1.5 mg/kg emicizumab QW SC up to the end of study. Participants continued to receive bypassing agent therapy to treat any breakthrough bleeds.
