Fostamatinib is an effective second-line therapy in patients with immune thrombocytopenia.


ABSTRACT: Fostamatinib demonstrated efficacy in phase 3 trials of adults with immune thrombocytopenia (ITP). Post hoc analysis compared patients who received fostamatinib as second-line therapy (after steroids ± immunoglobulins) versus third-or-later-line therapy (after ?2 prior lines of therapy including a second-line agent). Platelet responses ?50 000/µl were observed in 25/32 (78%) second-line and 54/113 (48%) third-or-later-line patients. Bleeding events were less frequent in second-line (28%) versus third-or-later-line (45%) patients. Responses once achieved tended to be durable in both groups. The safety profile was similar in both groups. In this post hoc analysis, fostamatinib was more effective as second-line than third-or-later-line therapy for ITP.

Fostamatinib demonstrated efficacy in phase 3 trials of adults with immune thrombocytopenia (ITP). Post hoc analysis compared patients who received fostamatinib as second-line therapy (after steroids ± immunoglobulins) versus third-or-later-line therapy (after ≥2 prior lines of therapy including a second-line agent). Platelet responses ≥50 000/µl were observed in 25/32 (78%) second-line and 54/113 (48%) third-or-later-line patients. Bleeding events were less frequent in second-line (28%) versus  ...[more]
