Trial Summary

What is the purpose of this trial?

This trial is testing a special radiation treatment called iopofosine I 131 in patients with hard-to-treat B-cell cancers. These patients have not responded well to other treatments. The treatment works by using a radioactive substance that targets and kills cancer cells.

Will I have to stop taking my current medications?

The trial requires that you stop any anti-cancer therapy at least two weeks before starting the study treatment. However, low-dose dexamethasone for symptom management is allowed. The protocol does not specify other medications, so it's best to discuss your current medications with the study team.

Eligibility Criteria

This trial is for adults with certain B-cell malignancies like multiple myeloma, CLL/SLL, and Waldenstrom Macroglobulinemia who have had previous treatments. They should be in a stable condition with adequate organ function and blood counts. People can't join if they've recently had other cancer therapies, significant radiation to the bone marrow, uncontrolled side effects from past treatments (except hair loss), or are dealing with another active cancer.

Inclusion Criteria

I have a tumor larger than 15mm or a liver nodule bigger than 10mm.

I have side effects from past treatments, but they are manageable.

I have been diagnosed with CNS lymphoma.

Exclusion Criteria

I have had full or half-body radiation before, but may still qualify based on specific conditions.

I have a history of cancer.

I haven't had cancer in the last 5 years, except for skin cancer.

• Iopofosine I 131

Trial Overview The study tests Iopofosine I 131 at different doses in patients with select B-cell cancers. Part A looks at previously treated patients while Part B focuses on those with Waldenstrom Macroglobulinemia after two prior therapies. The drug's given through an IV and aims to see how well it works against these cancers.
