Description of intervention(s) / exposure
Treatment: Drugs - Emicizumab

Experimental: Cohort A: 1.5 mg/kg Emicizumab QW - Participants will receive emicizumab at a loading dose of 3 milligrams per kilogram (mg/kg) QW SC for the first 4 weeks followed by a maintenance dose of 1.5 mg/kg QW SC for a minimum of 52 weeks, or until unacceptable toxicity, discontinuation from the study due to any cause, or other criteria set forth in the protocol, whichever occurs first.

Experimental: Cohort B: 3 mg/kg Emicizumab Q2W - Participants will receive emicizumab at a loading dose of 3 mg/kg QW SC for the first 4 weeks followed by a maintenance dose of 3 mg/kg every 2 weeks (Q2W) SC for a minimum of 52 weeks, or until unacceptable toxicity, discontinuation from the study due to any cause, or other criteria set forth in the protocol, whichever occurs first.

Experimental: Cohort C: 6 mg/kg Emicizumab Q4W - Participants will receive emicizumab at a loading dose of 3 mg/kg QW SC for the first 4 weeks followed by a maintenance dose of 6 mg/kg every 4 weeks (Q4W) SC for a minimum of 52 weeks, or until unacceptable toxicity, discontinuation from the study due to any cause, or other criteria set forth in the protocol, whichever occurs first.
