The purpose of this study is to determine efficacy of guanfacine immediate release (GIR) for the treatment of hyperactivity/impulsivity and inattention in children 6-12 years of age with Down syndrome (DS) after 8 weeks of treatment.
The goal of this interventional study is to determine the strength of cobolimab and dostarlimab that is most tolerated in children and young adults who have advanced solid tumors. This study also aims: (a) to check if it is safe to use cobolimab and dostarlimab combination in children and young adults, (b) to see how to manage the side effects that may occur, and (c) the effect of this treatment in participants
This phase III trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant. The treatments used to prepare for HCT reduce the body's natural infection-fighting ability and increase the likelihood of an infection with a virus called cytomegalovirus. "Prophylaxis" means to take a drug to prevent a disease or side effect. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.
Substudy 01A is part of a platform study. The purpose of this study is to assess the efficacy and safety of zilovertamab vedotin in pediatric participants with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL), diffuse large B-cell lymphoma (DLBCL)/Burkitt lymphoma, or neuroblastoma and in pediatric and young adult participants with Ewing sarcoma.
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.
The purpose of this study is to find out if a drug called lurbinectedin (the "study drug") is safe and effective at treating people with recurrent or relapsed solid tumors, including Ewing sarcoma.
