Statistical methods / analysis
The total sample size for this study is 148 (74 in each arm) after taking a 10% dropout rate into account. In general, data will be summarised using descriptive statistics (mean, median, standard deviation, minimum and maximum) or frequency counts and percentages, as appropriate to the type of data. Baseline will be defined as the last available, valid, non-missing assessment prior to dosing. The primary endpoint of the study is the evaluation of AUC(0-inf).

The following additional PK parameters will also be analysed:
• AUC(0-last);
• Cmax;
• Time to Cmax (tmax);
• Terminal half-life (t½);
• Vz;
• Terminal rate constant (slowest rate constant of the disposition)
• Clearance;
• %AUCextrap;

Summary
Brief summary
ISU305 is being developed by ISU Abxis as a proposed biosimilar to eculizumab (Soliris® marketed by Alexion in the European Union [Soliris]). Soliris is approved for the treatment of patients with paroxysmal nocturnal haemoglobinuria (PNH) or atypical haemolytic uraemic syndrome (aHUS), disorders associated with dysregulated complement activation.
