Detailed Description:
This multi-center, single-arm study of epratuzumab is in patients with Waldenström's Macroglobulinemia (WM) who failed chemotherapy. After baseline evaluations, patients receive epratuzumab infused over approximately 30-60 minutes at 360 mg/m2, administered once weekly for 4 consecutive weeks (days 1, 8, 15, 22). Post-treatment evaluations occur on the day of the last infusion, then at 6 and 12 weeks. Patients without progression of disease continue long-term follow up until disease progression or for at least 5 years, with evaluations every 3 months for 2 years, then semi-annually. Otherwise, follow-up is only required until resolution of any treatment related abnormalities.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Documented diagnosis of Waldenström's Macroglobulinemia using criteria proposed at 2nd International Workshop on WM, Athens, Greece, 2002.
  • Measurable disease, defined as serum monoclonal IgM protein ≥1000 mg/dL by electrophoresis.
  • Lymphoplasmacytic infiltration of the bone marrow >10% involvement.
  • Failed at least one, but no more than 3, regimen(s) of prior therapy.
