Study Groups

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

Cohort 1

For Phase 1, a Coagulation Factor VIIa variant by intravenous route, 18 μg/kg, followed by ascending doses by subcutaneous route, 10 μg/kg, 20 μg/kg, 30 μg/kg, 40 μg/kg, and 60 μg/kg, for PK and PD assessment. For Phase 2, Coagulation Factor VIIa, 20 μg/kg by subcutaneous route, administered on demand during bleeding episodes for a maximum of 3 doses as needed for hemostasis.

Group Type EXPERIMENTAL

Coagulation Factor VIIa variant

Intervention Type BIOLOGICAL

Single intravenous dose and ascending doses of subcutaneous injection of MarzAA, followed by a fixed dose of MarzAA for the treatment of bleeding episodes

Cohort 2

For Phase 1, a Coagulation Factor VIIa variant by intravenous route, 18 μg/kg, followed by ascending doses by subcutaneous route, 30 μg/kg, 45 μg/kg, 60 μg/kg, 120 μg/kg, and 180 μg/kg, for PK and PD assessment. For Phase 2, Coagulation Factor VIIa, 60 μg/kg by subcutaneous route, administered on demand during bleeding episodes for a maximum of 3 doses as needed for hemostasis.
