Summary
Brief summary (as posted)
This phase I/II trial is studying the side effects and best dose of oblimersen and to see how well it works in treating patients with relapsed or refractory Waldenstrom's macroglobulinemia. Biological therapies such as oblimersen may interfere with the growth of the cancer cells and slow or stop the growth of Waldenstrom's macroglobulinemia.

- Arm I
- description
- Phase I: Patients receive oblimersen IV continuously on days 1-7. Treatment repeats every 3 weeks for up to 8 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 1-6 patients receive escalating doses of oblimersen until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Phase II: Patients receive treatment as in phase I at the MTD of oblimersen. Patients are followed every 3 months for 2 years.

Primary outcomes (1)
- measure
- Maximum tolerated dose determined by the number of dose-limiting toxicity incidents graded according to CTC standard toxicity (Phase I)
- timeFrame
- 21 days
- description
- Hematologic dose-limiting toxicity measures will be assessed using the continuous variables as the outcome measures (primarily nadir and percent change from baseline values) as well as categorization.
