Proteasome Inhibitor

Bortezomib + Rituximab for Waldenström's Macroglobulinemia

Phase 2

Waitlist Available

Led By Sheeba Thomas, MD

Research Sponsored by M.D. Anderson Cancer Center

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Patients with symptomatic macroglobulinemic lymphoma who have had no prior treatment, or whose prior treatment has been limited to steroids and/or alpha-interferon, are eligible. Macroglobulinemic lymphoma includes patients with either biopsy proven clonal lymphocytic or lymphoplasmacytic proliferation and monoclonal IgM. Also included are symptomatic patients with clonal proliferation producing a pathologic monoclonal IgM that causes cryoglobulinemia, peripheral neuropathy or cold agglutinin hemolytic anemia.

Must not have

Patient has >/= Grade 2 peripheral neuropathy on baseline evaluation.

Patient with a lifetime cumulative dose of > 450 mg/m^2 of anthracyclines.

Timeline

Screening 3 weeks

Treatment Varies

Follow Up after 3 (35 day) cycles of treatment

Awards & highlights

No Placebo-Only Group

Summary

This trial is testing if a combination of drugs can help to control WM, as well as the safety and tolerability of the combination.

Who is the study for?

This trial is for adults with Waldenstrom's Macroglobulinemia who haven't had prior treatment or only had steroids/alpha-interferon. They must have no serious heart issues, acceptable liver and kidney function, not be pregnant or breastfeeding, and willing to use birth control. People with certain health conditions like severe neuropathy, active hepatitis B, recent heart attack, other active cancers (except some skin cancers), or very low blood counts are excluded.

What is being tested?

The study tests if a combination of drugs called Bortezomib and Rituximab can manage Waldenstrom's Macroglobulinemia effectively. It also evaluates the safety of this combo followed by other treatments and checks if it allows stem cell collection for potential future transplants.

What are the potential side effects?

Possible side effects include allergic reactions to the drugs' components (like boron or murine proteins), nerve damage (neuropathy) if already present could worsen, fatigue from anemia due to bone marrow involvement in disease process might increase after therapy.
