Primary Outcome Measures:
  • Overall response rate (proportion of patients with best response of complete response (CR), unconfirmed response (CRu), partial response (PR)) for each group from Phase II [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Clinical benefit rate (proportion of patients with best response of CR, CRu, PR, stable disease (SD)) for each group from Phase II [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and tolerability of Fostamatinib Disodium [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
  • Progression free survival for each Phase II group [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Overall survival for each Phase II group [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: April 2007
Study Completion Date: October 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fostamatinib Disodium Drug: Fostamatinib Disodium
200 mg PO BID
Other Name: R935788, fostamatinib

Detailed Description:

This multicenter, open-label study of Fostamatinib Disodium will take place in two phases.

Phase I Two cohorts, of 6 patients each, will be sequentially assigned to receive 200 mg (Cohort 1) and 250 mg (Cohort 2) PO bid of R788. Patients will be enrolled at 250 mg bid in Cohort 2 only if < 1/6 patients in Cohort 1 experience dose-limiting toxicity (DLT) during the initial 28-day treatment period. If 2 or more patients in Cohort 1 experience DLT during the initial 28-day treatment period, patients in Cohort 2 will receive 150 mg PO bid.

Patients who do not experience DLT or disease progression may continue treatment at the assigned dose level until disease progression, toxicity or withdrawal. Patients who experience DLT may resume treatment at a lower dose level (dose will be decreased by 50 mg) when the toxicity grade has decreased to ≤ 1. Once all patients in Phase I have completed 28 days of treatment, the optimal dose of Fostamatinib Disodium, based on safety and anti-tumor activity, will be determined.

Phase II 48 additional patients, 3 groups of 16 patients each, will receive Fostamatinib Disodium at the optimal biologic dose PO bid until tumor progression, limiting toxicity or withdrawal. Group 1 will consist of patients with diffuse large B-cell lymphoma (DLBCL), Group 2 will consist of patients with follicular lymphoma, and Group 3 will consist of patients with mantle cell lymphoma, mucosa-associated lymphoid tissue (MALT) lymphoma, marginal zone lymphomas, small lymphocytic lymphomas (SLL), and chronic lymphocytic leukemia (CLL).


Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients must be > 18 years old.
  2. Patients must be willing and able to give written informed consent by signing an IRB-approved Informed Consent Form prior to admission to this study and must fully understand the requirements of the study and be willing to comply with all study visits and assessments.
  3. Patients with relapsed/refractory B-cell malignancy, (DLBCL, follicular lymphoma, mantle cell lymphoma, MALT lymphoma, marginal zone lymphoma, CLL or SLL), who have failed at least one prior treatment regimen and for whom no standard therapy exists; patients who are intolerant of standard therapy or who are not candidates for available standard therapy may also be included.
  4. Patients must have measurable disease.
  5. Patients may be male or female. Men, if sexually active, must agree to use at least one medically acceptable form of birth control for the duration of the study and for 30 days thereafter. Sexually active women of childbearing potential must have a negative serum pregnancy test, and agree to use two independent methods of birth control for the duration of the study and for 30 days thereafter.

Exclusion Criteria:

  1. Patients with T-cell lymphoma or primary CNS lymphoma
