This study is about a special medicine called iopofosine I 131, used to treat certain B-cell malignancies (cancers of the blood cells). These include diseases like multiple myeloma, a bone marrow cancer, and Waldenstrom Macroglobulinemia (WM), a type of non-Hodgkin lymphoma. This study has two parts. Part A checks how well iopofosine I 131 works in various B-cell cancers that have been hard to treat with regular medicines. Part B focuses on patients with WM who have already tried at least two different treatments. Iopofosine I 131 is a type of radiotherapy, meaning it uses radiation to target and kill cancer cells. It is specifically designed to enter these cancer cells and destroy them from the inside. This medicine has shown promise in experimental models, which means it could potentially help people with these challenging diseases.
- Participation involves receiving the medicine through an IV (intravenous) line.
- Eligible patients must have tried other treatments before and still need help.
- Some risks may include side effects from radiation or other medical concerns.
