Primary objective: Efficacy (i.e. recovery of coagulation factors and haemostatic parameters)

60 subjects (per-protocol population N=43)

Exposure: octaplas® 14.9 mL/kg; octaplasLG ® 15.3 mL/kg

A comparative, open-label, randomized, cross-over Phase I trial in healthy volunteers to investigate the relative efficacy, safety and

tolerability of octaplasLG® vs. octaplas®
