What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called iopofosine I 131 for certain types of blood cancer, specifically targeting Waldenstrom Macroglobulinemia (WM). The goal is to determine if iopofosine I 131 can benefit patients whose cancer has returned or not improved after other treatments. Suitable candidates have WM and have tried at least two different treatments but still exhibit symptoms or measurable signs of the disease. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

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.

Is there any evidence suggesting that iopofosine I 131 is likely to be safe for humans?

Research has shown that iopofosine I 131 has been tested for safety in patients with various B-cell cancers. In studies where patients received multiple doses, researchers used a standard system to track side effects. Although specific data from those studies is not provided here, the FDA has granted iopofosine I 131 "breakthrough therapy designation." This status indicates it could offer significant benefits over current treatments, particularly for individuals with relapsed or hard-to-treat Waldenström Macroglobulinemia. However, like any medical treatment, it can have side effects, so participants should discuss potential risks with their healthcare provider.12345

Why do researchers think this study treatment might be promising for Waldenstrom Macroglobulinemia?

Unlike the standard treatments for Waldenstrom Macroglobulinemia, which often include chemotherapy and monoclonal antibodies, Iopofosine I 131 introduces a novel approach by using a radioactive isotope. This treatment uniquely delivers radiation directly to the cancer cells, potentially sparing more healthy tissue than traditional methods. Researchers are excited about Iopofosine I 131 because it targets the cancer at a cellular level, which could lead to more effective and precise treatment outcomes with potentially fewer side effects.

What evidence suggests that iopofosine I 131 could be an effective treatment for Waldenstrom Macroglobulinemia?

Research has shown that Iopofosine I 131 holds promise for treating Waldenstrom Macroglobulinemia (WM). In studies with patients who had tried other treatments, Iopofosine I 131 achieved an impressive 83.6% overall response rate, indicating that most patients experienced some improvement. Additionally, the clinical benefit rate reached 98.2%, showing that nearly all patients experienced positive effects. Participants in this trial will receive Iopofosine I 131, which the FDA has recognized for its potential by granting it a breakthrough designation, highlighting its effectiveness for patients with relapsed or hard-to-treat WM.12456

Are You a Good Fit for This Trial?

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.

What Are the Treatments Tested in This Trial?

Interventions

  • CLR 131
  • 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.
