What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine the optimal dose and assess the side effects of a new treatment that combines radiolabeled monoclonal antibody therapy with chemotherapy for Hodgkin lymphoma. The treatment specifically targets cancer cells while sparing healthy ones, potentially benefiting patients whose cancer hasn't responded to standard treatments or has recurred. Participants should have Hodgkin lymphoma that did not respond to initial treatment or has returned after treatment, with evidence of the disease from scans or a biopsy. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss your specific medications with the trial team to get a clear answer.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Past studies have shown that radiolabeled monoclonal antibody therapy is safe and tolerable for patients with similar conditions, meaning most patients did not experience severe side effects. Research indicates that combining this therapy with BEAM chemotherapy (a mix of drugs that stop cancer cells) was effective and safe in other trials.

Carmustine can cause serious lung problems, so doctors must carefully weigh the risks and benefits for each patient. Cytarabine is generally safe, with only minor side effects reported, and serious issues are rare.

Etoposide has been used for many years, and while it can have side effects, they are usually manageable. Melphalan is also widely used for similar cancer treatments and is considered safe, though it can have side effects like all cancer drugs.

This trial is in the early stages, so researchers are primarily focused on finding the safest dose and understanding the side effects of the new combination with radiolabeled monoclonal antibodies. Safety data is still being collected, but past studies of the individual treatments provide some reassurance. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this treatment for Hodgkin Lymphoma because it combines a radiolabeled monoclonal antibody with chemotherapy, offering a unique approach. Most treatments rely on chemotherapy alone, but this approach uses an antibody tagged with a radioactive particle to directly target cancer cells, sparing more healthy tissue. This targeted action could potentially make the treatment more effective and reduce side effects compared to standard chemotherapy regimens. Additionally, incorporating a radiolabeled component may enhance the ability to deliver radiation directly to cancer cells, offering a promising advancement in treatment efficacy.

What evidence suggests that this trial's treatments could be effective for Hodgkin lymphoma?

In this trial, participants will receive radiolabeled monoclonal antibody therapy using yttrium-90 basiliximab, which may be effective for Hodgkin lymphoma. This treatment targets cancer cells while sparing normal cells. Studies have found that a similar treatment, 90Y-daclizumab, helped 50% of patients with recurring Hodgkin's lymphoma. Participants will also receive a chemotherapy regimen known as BEAM, which includes carmustine, etoposide, cytarabine, and melphalan. These drugs effectively stop cancer cells from growing and spreading. For instance, etoposide showed an 84% success rate in some studies. Together, these treatments aim to eliminate more cancer cells before a stem cell transplant. ^{6 7 8 9 10}

Are You a Good Fit for This Trial?

This trial is for adults with Hodgkin lymphoma that didn't respond to initial treatment or came back after therapy. Participants must have acceptable organ function, not be pregnant or breastfeeding, agree to use birth control, and have collected enough stem cells for transplant. They should not have had certain previous treatments like high-dose chemo with stem cell transplant or radiation to critical organs.

Inclusion Criteria

Hodgkin lymphoma that is:

Pathology confirmation of HL with City of Hope (COH) pathology review

PIF (primary induction failure): did not enter complete remission with first line of therapy; Note: a patient with PIF who responds to salvage therapy with a PR or CR is also eligible (and would be considered PIF-sensitive)

Exclusion Criteria

Positive human immunodeficiency virus antibody

Lymphocyte-predominant Hodgkin lymphoma

Prior high dose chemotherapy with autologous stem cell transplant, or prior allogeneic transplantation

What Are the Treatments Tested in This Trial?

Interventions

• Basiliximab
• Carmustine
• Cytarabine
• Etoposide
• Melphalan
• Radiolabeled Monoclonal Antibody Therapy
• Yttrium Y 90-labeled basiliximab

Trial Overview

The study tests a radiolabeled monoclonal antibody (yttrium Y 90-labeled basiliximab) combined with BEAM chemotherapy before a stem cell transplant in patients whose Hodgkin lymphoma has relapsed or was resistant from the start. The goal is to see how well this approach works and what the best dose of the antibody therapy might be.

How Is the Trial Designed?

Group I: Treatment (radiolabeled monoclonal antibody, chemotherapy) Experimental Treatment 9 Interventions

DOSIMETRY STUDY: Patients receive basiliximab IV and indium In 111 basiliximab IV on day -21. Patients undergo indium In 111 imaging scans daily. Patients with appropriate biodistribution continue on to treatment. TREATMENT: Patients receive basiliximab IV and yttrium Y 90 basiliximab IV on day -14. Patients also receive BEAM chemotherapy comprising carmustine IV over 2 hours on days -7 and -6, etoposide IV BID over 4 hours and cytarabine IV over 2 hours BID on days -5 to -2, and melphalan IV on day -1. Patients undergo autologous hematopoietic progenitor cell infusion on day 0.
