Phase I/II Study of G3139 (Genasense) in Patients With Waldenstrom's Macroglobulinemia


PRIMARY OBJECTIVES:

I. To determine the maximally tolerated dose (MTD) and recommended dosing for Genasense in
patients with relapsed or refractory WM following prior chemotherapy. (Phase I) II. To
determine the response rate to Genasense in patients with relapsed or refractory WM
following prior chemotherapy.

III. To determine the safety of Genasense in patients with relapsed or refractory WM
following prior chemotherapy.

IV. To describe possible clinical benefit from Genasense treatment of relapsed or refractory
WM including duration of response, survival, erythropoietin use, improvement in hemoglobin >
11 g/dl, and Improvement in platelet count > 100,000/mm^3.

OUTLINE: This is a multicenter, dose-escalation study.

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.


Inclusion Criteria:

Type of Study:

Interventional

Study Design:

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Maximum tolerated dose determined by the number of dose-limiting toxicity incidents graded according to CTC standard toxicity (Phase I)

Outcome 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.

Outcome Time Frame:

21 days

Safety Issue:

Yes
