Flebogamma® DIF has a proven efficacy and tolerability in treating immune thrombocytopenia purpura (ITP)

Proven efficacy in autoimmune disease1,2

The efficacy of Flebogamma® DIF in treating ITP has been demonstrated in 3 different clinical trials1,2

Table Efficacy Clinical Trials Table Regression Hemorrhage/Bleedings
  • Flebogamma® DIF had a response rate of ≥70%1,2
  • Flebogamma® DIF was effective in raising the platelet count with most patients responding in less than 3 days1,2
  • In trial B, 100% of pediatric patients* (n=12) responded to Flebogamma® DIF 10% and improved hemorrhagic episodes during the clinical follow-up period2

Proven tolerability in autoimmune disease1,2

In the ITP trial of Flebogamma® DIF 5% all potentially related AEs were graded as mild to moderate in intensity1

Chart severity AEs Chart severity AEs

In the ITP trials of Flebogamma® DIF 10%2, AEs were mainly graded as mild to moderate in intensity

  • Only 5 adult patients experienced serious AEs, which resolved without sequelae (n=64)2
  • Zero serious AEs in pediatric patients in trial B (n=12)2
  • The nature and severity of trial A and trial B AEs are consistent with what is expected for IVIG therapies for patients with chronic ITP2
Chart Flebogamma DIF 10% treatment 1 AE Trial A

Subjects treated with Flebogamma® DIF 10% with at least 1 AE occurring between the start of IVIG infusion visit and the last follow-up visit (n=16 in Trial A; n=53 in Trial B)

The most common AEs in trial A were petechiae, ecchymosis, headache and pyrexia2

The most common AEs in trial B were headache, nausea, pyrexia and chills. Nausea, vomiting and hypotension were much more frequent in children than in adult subjects2

Six serious AEs were reported in 2 adults from Trial A and 3 adults from Trial B: leukopenia and decreased hemoglobin in 1 subject (probably drug-related); soft tissue inflammation (not drug-related); severe headache in 2 subjects and thrombosis (possibly drug-related)2
