Trial Overview
Purpose
This phase III, open label extension study is designed to determine whether fostamatinib is safe and effective in treating patients with persistent/chronic immune thrombocytopenic purpura (ITP) over a 5 year period.
Comments
According to a Grifols media release, European Commission has approved TAVLESSE (fostamatinib) for the treatment of chronic immune thrombocytopenia (ITP) in adult patients who are refractory to other treatments.
Based on the data from the Phase 3 clinical program [Study 047, 048 and 049] the U.S. FDA approved TAVALISSE (fostamatinib disodium) for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia. Together with an initial proof of concept study, the NDA included 163 ITP patients (as of 17th Apr 2018).
According to a Kissei Pharmaceutical media release, based on the results of the Phase 3 clinical trials of TAVALISSE in ITP patients in Japan and outside of Japan, the Ministry of Health, Labour and Welfare (MHLW) has granted manufacturing and marketing approval for the oral spleen tyrosine kinase inhibitor, TAVALISSE (Tab. 100mg and 150mg (generic name: fostamatinib disodium hexahydrate)), for chronic idiopathic thrombocytopenic purpura (chronic ITP).
Primary Endpoints
Percentage of Subjects Who Achieved Platelet Count of at Least 50,000/µL Within 12 Weeks of Beginning Treatment up to 12 Months (Fostamatinib in 047/048 or 049):Version 1
description: Percentage of subjects who achieved platelet count of at least 50,000/µL within 12 Weeks of beginning treatment up to 12 months was analyzed among all subjects who received active treatment in one of the prior studies (C788-047 or C788-048), in the current extension study (C788-049), or in both prior and current studies. Treated Population was defined as all enrolled and treated subjects.
time_frame: Up to 12 months
Percentage of Subjects Who Achieved Platelet Count of at Least 50,000/µL Within 12 Weeks of Beginning Treatment up to 12 Months (Placebo in 047/048 and Fostamatinib 049): Version 2
description: A within-subject, between-study comparison of platelet counts for subjects who were previously treated with placebo in one of the prior studies (C788-047 or C788-048) was prospectively defined in the protocol (version 2). Achievement of platelet response by 12 weeks and maintenance of platelet response for 12 weeks was analyzed among subjects who had been randomized to placebo in one of the prior studies (C788-047 or C788-048). Treated Population was defined as all enrolled and treated subjects.
time_frame: Up to 12 months
Other Endpoints
Duration of Platelet Response Based on Platelet Count and Rescue Medication
description: The duration of platelet response was defined as the time from when the subject first achieved a platelet count of at least 50,000/µL, until the first of 2 visits with platelet counts < 50,000/µL that were at least 4 weeks apart without an intervening visit with a platelet count less than equal to (≤) 50,000/µL unrelated to rescue therapy. Duration of platelet response was analyzed using the Kaplan-Meier method. Treated Population was defined as all enrolled and treated subjects. Here, a number of subjects analyzed included all subjects evaluable for this endpoint.
time_frame: Up to 12 months
Percentage of Subjects in Whom a Reduction in the Dose of Concomitant ITP Therapy Can be Achieved While Maintaining an Adequate Platelet Count
description: The percentage of subjects in whom a reduction in the dose of concomitant ITP therapy could be achieved while maintaining an adequate platelet count, the reduction event was clarified to apply only to reductions in the dose of concomitant ITP therapy occurring within a period of platelet response and the reduction event was not be prompted by an adverse event.
time_frame: Up to 12 months [1]

Results
Therapeutic efficacy
Data from the FIT phase III trials (047, 048 and 049 studies) demonstrated that fostamatinib was effective for certain immune thrombocytopenic purpura patients. Additionally, the benefit was consistent across all sub-groups analysed including TPO (blood platelet production booster) experienced patients who had limited treatment options remaining [2] .
Updated results from the open-label extension demonstrated that 56% of subjects with a stable response maintained the response for ≥24 months. Of 27 patients with a stable response, 21 (78%) maintained the response at Month 12 of fostamatinib treatment, and 15 (56%) at Month 24. At Month 12, median platelet count for the 49 subjects was 72,000/µL (range: 9000-333,000 µL). For the 32 subjects at Month 24, median platelet count was 80,500/µL (range: 7000-315,000/µL). An overall platelet response was achieved by 57/123 (46%) patients. In the FIT phase III long-term extension study 049, 118 patients who responded to fostamatinib in the parent studies (047 and 048) and exposed to fostamatinib for a median of 13 months through the combined parent and 049 trials had a median platelet count of 96 000/µL of blood.In addition, 41 out of 44 former placebo patients from the 047 and 048 studies that enrolled in the 049 study, 22% (n = 9/41, p = 0.0078) achieved a prospectively defined stable platelet response [3] [2] [4] [5] .
Adverse events
Phase III: Mild or moderate adverse events (AEs), with gastrointestinal related AEs were observed most frequently, and were reversible over time. No new or unusual safety issues were reported in the randomised, double-blind, phase III FIT 1 and FIT 2 trials evaluating fostamatinib versus placebo in patients with persistent or chronic ITP [5] .
In the FIT phase III long-term extension study 049, AEs were reported by 95 (77%) patients and were mild/moderate in 92 (75%). The most common AEs were diarrhea and hypertension, which were manageable with targeted treatment, fostamatinib dose modifications, or treatment withdrawal (5 patients withdrew due to diarrhea and none due to hypertension). Serious adverse events (SAE) were reported in 28 patients (23%), were considered unrelated to fostamatinib in 23 patients (19%) and included bleeding-related SAEs in 11 subjects (9%), thrombocytopenia in 6 subjects (5%), epistaxis in 3 (2%), sepsis in 2 (2%) and transaminases increased in 2 (2%). Adverse events were consistent with those reported during the placebo-controlled trials [3]
