Reduced Intensity BMT for Solid Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if a less intense chemotherapy combined with a specific bone marrow transplant procedure is safe and feasible for individuals with very high-risk solid cancers. It involves administering drugs such as cyclophosphamide (Cytoxan or Neosar) and melphalan to help the body accept the new bone marrow. The trial seeks participants with difficult-to-treat cancers like neuroblastoma or stage 4 rhabdomyosarcoma after standard treatments have failed. Potential participants must have a related bone marrow donor with some genetic matches. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify whether you need to stop taking your current medications. It's best to discuss your specific situation with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study using lower-intensity treatments with fludarabine and melphalan showed some possible side effects. However, these drugs are generally considered safe for treating blood cancers. When melphalan is used in smaller doses with fludarabine, it has proven safe and effective for transplants.
Research has shown that using low-dose total body irradiation (TBI) at 200 cGy, as in this study, does not significantly increase the risk of developing new cancers compared to chemotherapy alone. Cyclophosphamide, another drug in the treatment plan, carries known risks, such as potential bladder problems and cancer, but these risks can be managed with preventive measures.
Tacrolimus, which helps prevent organ rejection after transplants, carries a higher risk of certain cancers, like skin and lymph gland cancers. Despite these risks, it is widely used because it helps ensure transplant success.
Overall, while each treatment carries risks, they are generally well-tolerated when managed properly.12345Why are researchers excited about this trial's treatments?
Researchers are excited about this treatment approach because it uses a reduced intensity conditioning regimen that could potentially make bone marrow transplants more tolerable for patients with solid cancers. Unlike standard high-dose chemotherapy regimens, which can be very taxing on the body, this method uses lower doses of drugs like Melphalan and Cyclophosphamide, along with a specific type of radiation. This might lead to fewer side effects and a quicker recovery. Additionally, by incorporating post-transplant Cyclophosphamide and immunosuppressive agents like Tacrolimus and Mycophenolic acid, this approach aims to reduce the risk of graft-versus-host disease, a common complication in bone marrow transplants.
What evidence suggests that this trial's treatments could be effective for high-risk solid tumors?
Research has shown that a combination of fludarabine, melphalan, and low-dose total body irradiation holds promise for treating high-risk conditions. In this trial, participants will receive this combination as part of the reduced intensity conditioning regimen to prepare for a bone marrow transplant while minimizing side effects. Studies have found that this method aids in the recovery of blood cells and facilitates successful integration of donor cells. Additionally, low-dose total body irradiation is linked to a reduced chance of cancer recurrence within a year. These findings suggest that this treatment combination could be effective for patients with very high-risk solid tumors.678910

Are You a Good Fit for This Trial?
This trial is for patients with high-risk solid tumors who have a low chance of survival and haven't responded well to standard treatments. They need normal kidney function, decent heart function, and good overall health status. Participants must have a related donor who's partially genetically matched for bone marrow donation.Inclusion Criteria
