Phase 2 Study of Zevalin Versus Zevalin and Motexafin Gadolinium in Patients With Rituximab-Refractory Low-grade or Follicular B-cell Non-Hodgkin's Lymphoma

• Status: Terminated
• Trial end date: 2015-05-01
• Target enrollment: 0
• Participant gender: All

Summary

The objectives of this study are to evaluate the efficacy and safety of the Zevalin regimen compared to Zevalin and motexafin gadolinium in patients with rituximab-refractory, low-grade or follicular Non-Hodgkin's Lymphoma (NHL).

Effectiveness of the experimental regimen assessed by complete response rate within 6 months of study entry (primary endpoint), complete response rate within 3 months of study entry, and overall response rate within 6 month of study entry.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

2. Histologically-confirmed follicular or indolent, marginal zone and small lymphocytic B cell non-Hodgkin's lymphoma

3. Progressive disease within 6 months of the end of a rituximab-containing regimen; or progressive disease at any time following 2 or more prior rituximab-containing regimens; or progressive disease while on rituximab-containing regimen.

4. At least 1 measurable tumor (> 1.5 cm in the long axis and > 1.0 cm in the short axis) that has not been irradiated previously or that has increased in size since previous irradiation

10. Bone marrow involvement < 25%

11. If men or women of reproductive potential, agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for at least 1 year following treatment with Zevalin

11. History of another clinically significant medical condition, metabolic dysfunction, physical examination finding, and/or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or that might affect interpretation of the results of the study or place the patient at high risk of treatment complications and/or of noncompliance with the study procedures

12. Major surgical procedure and/or significant traumatic injury (that which could interfere with the patient's ability to receive protocol therapy as determined by the principal investigator) within the 28 days prior to Study Day 1, and/or patient is anticipated to require a major surgical procedure during the study period
