Study of ONTAK® to Treat Cutaneous T-Cell Lymphoma (CTCL)

Phase 4

Completed

• Conditions: Lymphoma, T-Cell, Cutaneous

• Registration Number: NCT00211198
• Lead Sponsor: Eisai Inc.

Brief Summary

The purpose of this research study is to evaluate how effective ONTAK is in the treatment of cutaneous T-cell Lymphoma (CTCL) and determine whether the presence of a type of protein called CD25 on the cancer cells makes a difference in how the body responds to the treatment.

The hypothesis is that there is no difference in response rate for patients whose tumor cells are CD25 positive or negative.
