|Follicular Lymphoma Small Lymphocytic Lymphoma Marginal Zone Lymphoma Lymphoplasmacytic Lymphoma Diffuse Large B Cell Lymphoma Mantle Cell Lymphoma Burkitt's Lymphoma||Drug: Imexon||Phase 2|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase II Study of Amplimexon® (Imexon for Injection) for the Treatment of Previously Treated Follicular and Aggressive Lymphoma in Adults|
- Overall Response Rate of of Participants to Imexon in the Treatment of Relapsed/Refractory Indolent and Aggressive Lymphomas [ Time Frame: One year ]CT, PET, or MRI scans for the assessment of objective tumor responses were performed at baseline, after cycle 2, and every 3 cycles thereafter until disease progression. Standard response criteria from the International Harmonization Project on Lymphoma were used for classification of objective tumor responses. Response was defined as PR (Regression of measuable disease and no new sites) if >= 50% decrease in sum of the product of the diameters of up to 6 largest dominant masses; no increase in size of other nodes (a) [18F]fluorodeoxyglucose (FDG)-avid or PET prior to therapy; one or more (PET) positive at previously involved site (b) Variably FDG-avid or PET negative; regression on CT.
- Median Time to Progression Free Survival in Participants With Relapsed/Refractory Indolent and Aggressive Lymphomas [ Time Frame: up to 25 months ]Measured from start of treatment until disease progression or death from any cause.

Subjects will be treated on Days 1-5 of 21-day treatment cycles for up to one year. Following pre-treatment with anti-emetics Amplimexon will be given by intravenous infusion over 60 minutes.
Amplimexon will be administered daily on Days 1-5 of 21-day treatment cycles as an intravenous infusion over a time course of 60 minutes. Subjects will receive 17 cycles of therapy for a total of one year on treatment. The Amplimexon starting dose for each subject in this study is 1000 mg/m² on each treatment day. Dose may be reduced by 25% for toxicity; after 2 dose reductions, subjects must be withdrawn from treatment.
Other Name: Amplimexon (imexon for injection)
A phase II exploratory trial of imexon in lymphoma is justified by: (1) the observation of clinical activity (partial response to the drug observed in phase I testing in a subject with refractory indolent lymphoma); (2) the finding that imexon prevents the development of human immunoblastic lymphoma in SCID mice; (3) the finding that lymphoma cell lines are killed by readily achievable doses; and (4) translational studies implicating the importance of the redox state of the cancer cell.
The dose and schedule chosen (1000 mg/m2 daily X 5 days every 3 weeks) is based on tolerability and subject acceptance in prior AmpliMed phase I studies.
The planned correlative studies should help to identify potential biomarkers for response to imexon and provide further insight into potential mechanisms of imexon action hypothesized from results of prior laboratory studies.
