Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients meeting specific inclusion and exclusion criteria will be enrolled in two stages, 19 patients in Stage 1 and 36 patients in Stage 2. Stage 2 will enroll if 4 or more patients exhibit a response at Week 8 or later in the study. All enrolled patients will be treated with Fostamatinib Disodium until disease progression. Efficacy will be assessed by tumor measurements using CT and PET (when indicated) scans and physical exam at baseline, and scans and physical exam of all disease-involved areas every 8 weeks until progression. Safety will be assessed by periodic physical exams, clinical laboratory studies, and adverse events. All patients will have a follow-up visit 30 days following last study drug treatment. Blood samples for PK assessment will be obtained from all patients enrolled in Stage 1 at protocol defined intervals.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Up to 61 patients (male and female) meeting the inclusion and exclusion criteria will be enrolled into this trial in two stages. All enrolled patients will be treated with R788 at 200 mg PO bid until disease progression. In the initial stage of the study, a total of 19 patients will be enrolled and treated with Fostamatinib Disodium. Should at least 4 patients exhibit a response at Week 8 or later of the study, the second stage of 36 patients will open to enrollment. Efficacy will be assessed by CT and PET scans (when indicated) and physical exam at baseline, and CT scans and physical exam of all disease-involved areas every 8 weeks until progression. Safety will be assessed by periodic physical exams, clinical laboratory studies, and adverse events. All patients will have a follow-up visit 30 days following last study drug treatment. Blood samples for PK assessment will be obtained from all patients enrolled in Stage 1 at protocol-defined intervals. Patients with accessible tumor tissue will be asked to undergo a biopsy for a fresh tissue sample for assessment of Syk activity in tumor tissue. Archived tissue samples from the initial diagnostic biopsy and the most recent biopsy for lymphoma will be obtained in the event a fresh tumor biopsy cannot be obtained. Patients who have accessible tumor tissue will be asked to consent to a second tumor biopsy at Week 8, to assess the impact of Fostamatinib Disodium treatment on the activity of Syk and its downstream markers. All baseline fresh or archived tumor tissue samples will undergo central pathology review to confirm the diagnosis of TCL.
