Efficacy and safety of a new intravenous immunoglobulin 10% formulation (octagam® 10%) in patients with immune thrombocytopenia.
Intravenous immunoglobulin (IVIg) has an established role in the treatment of immune thrombocytopenia (ITP). The safety and efficacy of a new ready-to-use IVIg 10% formulation (octagam(®) 10%) were investigated in a prospective phase III study in 116 adult patients with ITP (platelet count ≤20×10(9)/l). Sixty-six patients had chronic ITP and 49 were newly diagnosed. Patients received octagam 10% 1 g/kg/day on two consecutive days; infusion rate was adjusted according to tolerability to a maximum of 0·12 ml/kg/minute. Eighty per cent of patients attained the primary efficacy endpoint of clinical response (platelet count ≥50×10(9)/l within 6 days of dosing). The median time to response was 2 days and the median duration of response was 12 days; mean response duration was 24·1 days. octagam 10% was well tolerated and effective in this population representative of adult patients with ITP, even at the maximum infusion rate of 0·12 ml/kg/minute, without unexpected safety issues.
