To determine if GAMMAPLEX raises the platelet count of subjects with chronic ITP to a threshold of 50 x 109/L, similar to that of published response \>60%. Also to assess the safety of GAMMAPLEX and determine if platelet counts are maintained at 50 x 109/L in subjects with chronic ITP for.
The primary objective is to determine if BPL's GAMMAPLEX raises the platelet count of subjects with chronic ITP to a threshold of 50 x 109/L, similar to that of published response \>60%. The secondary objectives are: 1) to determine the safety of GAMMAPLEX at the dosage used in this study. 2) to determine if GAMMAPLEX maintains platelet counts of ³ 50 x 109/L in subjects with chronic ITP for a period of time similar to that of a published data.
Dosage form: Gammaplex® is a sterile liquid of 5 % w/v normal immunoglobulin. Gammaplex® contains 5 g/100 mL of human normal immunoglobulin (i.e. 50 g/L, of which virtually 100% is IgG). The first course of GAMMAPLEX will be administered as an intravenous infusion of 1 g/kg on each of 2 consecutive days. If required, a further 1 or 2 courses on the same dosage regimen may be administered in the period Day 32 to Day 90 following the first course of GAMMAPLEX.
