Cell Therapy + Chemo + TBI for Skin Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if adding total body irradiation (TBI) to a cell therapy and chemotherapy mix is more effective for treating metastatic melanoma, a type of skin cancer that has spread to other parts of the body. Participants will receive either cell therapy with chemotherapy alone or with the addition of TBI. Those diagnosed with metastatic melanoma and having a removable tumor for the study might be suitable candidates. The study seeks to identify which combination enhances the immune system's ability to fight the cancer. Regular follow-ups will monitor the cancer's response to the treatment. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people, offering participants a chance to contribute to significant advancements in cancer therapy.
Do I need to stop my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, you must wait more than four weeks since any prior systemic therapy and six weeks since any anti-CTLA4 antibody therapy before joining the trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that using young tumor-infiltrating lymphocytes (TILs) to treat advanced melanoma is safe and generally well-tolerated. Most side effects arise from chemotherapy and a drug called high-dose aldesleukin, which boosts the immune system. Studies have found these side effects can be managed.
When TIL therapy combines with total body irradiation (TBI), the treatment remains promising. However, reports of serious side effects, including some deaths, have occurred, though these were often not directly caused by the treatment. It's important to understand that while TIL therapy with TBI can be effective, there is a risk of side effects.
Overall, TIL therapy, with or without TBI, is gaining attention for its potential to help patients with advanced melanoma. Anyone considering joining a clinical trial should discuss the possible risks and benefits with their healthcare provider.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because they offer a novel approach to fighting skin cancer. Unlike traditional treatments like surgery, radiation, or standard chemotherapy, these new options harness the power of the body's own immune system. The use of young Tumor Infiltrating Lymphocytes (TIL) is a standout feature, as these cells are specially reprogrammed to target and attack cancer cells more effectively. Additionally, the combination with high-dose aldesleukin and the optional use of Total Body Irradiation (TBI) helps to enhance the immune response, potentially leading to better outcomes for patients. This innovative approach could represent a significant advancement in immunotherapy for skin cancer.
What evidence suggests that this trial's treatments could be effective for metastatic melanoma?
Research has shown that young tumor-infiltrating lymphocytes (TIL) can yield positive results for patients with advanced melanoma, a type of skin cancer. In earlier studies, TIL therapy reduced tumors in about 58% of patients, meaning more than half experienced tumor shrinkage. In this trial, one group of participants will receive TIL therapy with chemotherapy. Previous studies showed that patients typically lived about 13.9 months with this combination. Another group will receive TIL therapy with chemotherapy and total body irradiation (TBI). Some studies reported better outcomes with this combination, with about 41.7% of patients surviving for at least two years. These encouraging findings suggest that TIL therapy, especially when combined with TBI, might effectively treat this skin cancer.678910

Are You a Good Fit for This Trial?
Adults aged 18-66 with metastatic melanoma, able to consent, and have a life expectancy over three months. They must be in good health otherwise, not HIV or hepatitis positive, and have a tumor suitable for cell extraction. Women can't be pregnant/breastfeeding; participants must use birth control during/after the trial.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Chemotherapy
Participants receive a non-myeloablative lymphodepleting chemotherapy regimen with cyclophosphamide and fludarabine over 7 days before cell therapy
Cell Therapy and IL-2 Administration
Participants receive tumor-infiltrating lymphocytes followed by high-dose aldesleukin every 8 hours for up to 5 days
Follow-up
Participants are monitored for safety and effectiveness after treatment, with regular follow-up visits for at least 5 years
What Are the Treatments Tested in This Trial?
Interventions
- Aldesleukin
- Cyclophosphamide
- Fludarabine
- Total Body Irradiation (TBI)
- Young TIL
- Young Tumor Infiltrating Lymphocytes
Trial Overview
The study is testing if adding total body irradiation (TBI) to chemotherapy before cell therapy improves outcomes in metastatic melanoma patients. Participants are split into two groups: one receives just chemo while the other gets chemo plus TBI before their own grown white blood cells are reintroduced.
