Ibritumomab Tiuxetan (Zevalin)+ Rituximab Maintenance

Phase 2
Terminated
Conditions
Non-Hodgkin's Lymphoma
Interventions
Registration Number
NCT00582166
Lead Sponsor
University of Wisconsin, Madison
Brief Summary

Subjects will receive the Ibritumomab Tiuxetan (Zevalin) therapeutic regimen; then rituximab consolidation and maintenance therapy every 3 months until disease progression

Detailed Description

The objective of this study is to estimate the median progression-free survival for patients receiving this regimen, along with the rate of complete response at 6 months, toxicities associated with this regimen, and laboratory correlates. Subjects will receive the Ibritumomab Tiuxetan (Zevalin) therapeutic regimen; then rituximab consolidation and maintenance therapy every 3 months until disease progression.

Primary Outcome Measures
NameTimeMethod
Median Progression Free Survival (PFS)up to 5 years, 9.5 months, from first day on treatment to last follow up

Estimate median progression free survival (PFS), where PFS is defined as the number of days from administration of Ibritumomab tiuxetan In111 (defined as day 1) until the participant develops progressive disease or death from NHL (Non-Hodgkin's Lymphoma).

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)At 12 months

To estimate overall survival, 95% confidence intervals will be used.

24-month Progression Free Survival (PFS)Up to 24 months

Estimate the 24 month progression free survival (PFS), where PFS is defined as the number of days from the first Ibritumomab tiuxetan administration (day 0) to the day the patient experiences an event of disease progression (or death). PFS is summarized as the percentage of patients that survived progression free after 24 months.

Progression is defined as any of the following:

- Appearances of any new lesions/sites during or after therapy.

* Increase of \>/= 50% in the SPD (sum of perpendicular diameter) from nadir measurement of all involved dominant lymph nodes and liver nodules and spleen nodules or unequivocal progression in any nonmeasurable disease or nondominant site.

* Increase by \> 50% in greatest diameter from nadir measurement of any previously involved dominant node \> 1.0 cm in its short axis.

Response RatesUp to 5 years and 9.5 months

To estimate the Complete Response and unconfirmed Complete Response rate (assessing Ibritumomab tiuxetan). Complete response is defined as the complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease related B-symptoms, and all dominant lymph nodes and nodal masses have regressed to normal size, and complete resolution of lymphoma in the bone marrow biopsy. Unconfirmed Complete Response (CRu) defined as the above, but with either a \> 1.5cm residual node that has decreased by \>75%, and/or individual nodes that were previously confluent that have decreased by \>75% in SPD, and/or indeterminate bone marrow (increased number or size of aggregates without cytologic or architectural atypia).

Number of Participants Experiencing Toxicities, Measured by CTCAE v3.0Up to 5 years and 9.5 months

To record the toxicities associated with this regimen.
