Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Conventional therapy is effective for diffuse aggressive lymphomas and low grade lymphomas, but is limited by relapse occurs in 40 to 50% of subjects.

This study assesses autologous stem cell transplant (ASCT) supplemented with high-dose therapy increases the event-free survival in diffuse aggressive lymphomas and low grade lymphomas, as an alternative to the limitations of conventional therapy.

Preliminary studies with rituximab in low grade lymphomas indicate a response rate of about 50% with very little toxicity. Rituximab is hypothesized to be a candidate for post-transplant therapy because the majority of malignant lymphomas express the CD20 antigen; rituximab has impressive independent anti-tumor activity; and the antibody has little toxicity outside of the acute administration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The first 4 subjects received rituximab weekly for 4 weeks at the standard dose of 375 mg/m2, starting 6 weeks after ASCT transplant.

After an observation period to assess acute and late toxicity for the first 4 subjects, subsequent subjects received induction as above followed by an additional 4 week course at 6-months post-ASCT.
