Dinutuximab With Chemotherapy, Surgery and Stem Cell Transplantation for the Treatment of Children With Newly Diagnosed High Risk Neuroblastoma

This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the cancer cells, this is a type of immunotherapy. When chemotherapy and immunotherapy are given together, during the same treatment cycle, it is called chemoimmunotherapy. This clinical trial randomly assigns patients to receive either standard chemotherapy and surgery or chemoimmunotherapy (chemotherapy plus dinutuximab) and surgery during Induction therapy. Chemotherapy drugs administered during Induction include, cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, and doxorubicin. These drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Upon completion of 5 cycles of Induction therapy, a disease evaluation is completed to determine how well the treatment worked. If the tumor responds to therapy, patients receive a tandem transplantation with stem cell rescue. If the tumor has little improvement or worsens, patients receive chemoimmunotherapy on Extended Induction. During Extended Induction, dinutuximab is given with irinotecan, temozolomide. Patients with a good response to therapy move on to Consolidation therapy, when very high doses of chemotherapy are given at two separate points to kill any remaining cancer cells. Following, transplant, radiation therapy is given to the site where the cancer originated (primary site) and to any other areas that are still active at the end of Induction. The final stage of therapy is Post-Consolidation. During Post-Consolidation, dinutuximab is given with isotretinoin, with the goal of maintaining the response achieved with the previous therapy. Adding dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy may be better at treating children with newly diagnosed high-risk neuroblastoma.

Comparing 123I-MIBG and 18F-MFBG Imaging in Patients With Newly Diagnosed, High Risk Neuroblastoma

This phase II trial evaluates whether an investigational scan (18F-MFBG positron emission tomography \[PET\]/computed tomography \[CT\] or PET/magnetic resonance imaging \[MRI\]) can accurately detect tumors in patients with newly diagnosed, high-risk neuroblastoma as well as standard of care imaging with 123 I-MIBG. 18F-MFBG is a radioactive diagnostic agent that is injected into a vein and taken up by tumor cells. The cells can then be visualized using PET/CT or PET/MRI scans. A PET scan uses radioactive material injected into the blood to show the internal workings of the body. A CT scan uses x-rays and a computer to produce a 3-dimensional image of the body. MRI uses radiofrequency waves and a strong magnetic field rather than x-rays to provide clear and detailed pictures of internal organs and tissues. Combining PET with CT or MRI may help doctors better understand the extent and the exact location of disease. Diagnostic procedures, such as 18F-MFBG PET/CT or PET/MRI, may detect tumors as well as or better than the current standard imaging with 123 I-MIBG in patients with newly diagnosed, high-risk neuroblastoma.

Testing the Addition of 131I-MIBG or Lorlatinib to Intensive Therapy in People With High-Risk Neuroblastoma (NBL)

This phase III trial studies iobenguane I-131 or lorlatinib and standard therapy in treating younger patients with newly-diagnosed high-risk neuroblastoma or ganglioneuroblastoma. Radioactive drugs, such as iobenguane I-131, may carry radiation directly to tumor cells and not harm normal cells. Lorlatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving iobenguane I-131 or lorlatinib and standard therapy may work better compared to lorlatinib and standard therapy alone in treating younger patients with neuroblastoma or ganglioneuroblastoma.

Treatment With Dinutuximab, Sargramostim (GM-CSF), and Isotretinoin in Combination With Irinotecan and Temozolomide After Intensive Therapy for People With High-Risk Neuroblastoma (NBL)

This phase II trial studies if dinutuximab, GM-CSF, isotretinoin in combination with irinotecan, and temozolomide (chemo-immunotherapy) can be given safely to patients with high-risk neuroblastoma after Consolidation therapy (which usually consists of two autologous stem cell transplants and radiation) who have not experienced worsening or recurrence of their disease. Dinutuximab represents a kind of cancer therapy called immunotherapy. Unlike chemotherapy and radiation, dinutuximab targets the cancer cells without destroying nearby healthy cells. Sargramostim helps the body produce normal infection-fighting white blood cells. Isotretinoin helps the neuroblastoma cells become more mature. These 3 drugs (standard immunotherapy) are already given to patients with high-risk neuroblastoma after Consolidation because they have been proven to be beneficial in this setting. Chemotherapy drugs, such as irinotecan and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. They may also affect how well immunotherapy works on neuroblastoma cells. Giving chemo-immunotherapy after intensive therapy may work better in treating patients with high-risk neuroblastoma compared to standard immunotherapy.
