Relapsed and Progressive Sonic Hedgehog Medulloblastoma With U1 Mutation Registry Study

The purpose of this study is to create a biobank for patients diagnosed with Sonic Hedgehog Medulloblastoma at Baylor College of Medicine/Texas Children's Cancer Center. A biobank is a facility that stores and manages biological samples (such as blood, tissue, or DNA) from individuals, along with detailed health information, for use in medical research to study diseases and develop new treatments. The investigators are requesting participants' permission to add their information and samples to this biobank. Being in this research study is voluntary; it is the participant's choice. If the participant joins this study, they can still stop at any time. If the participant decides to participate, the investigators will review the participant's clinical medical records, demographics, treatment history, family history, and imaging. The investigators will also collect biological samples from the participant and the biological parents' buccal swabs (optional). The participation in this biobank will last about 5 years from the decision to participate. Why am I being asked to participate? The participant or their child is invited to participate in this study if the participant or their tumor may have a U1 mutation. U1 mutation is associated with an error in the gene that splices the tumor DNA, leading to random splicing that may increase the tumor mutation burden and generate novel tumor neoantigens (targets). Studying the U1 mutation will enable the investigator to design more effective therapies and guide future treatments for patients with relapsed or refractory sonic hedgehog medulloblastoma, thereby improving their outcomes and quality of life. Moreover, the investigators aim to determine whether germline mutations inherited from parents may increase the risk of medulloblastoma in their offspring. The participant will receive no direct benefit from their participation in this study. However, participation in this study may help the investigators better understand SHH Medulloblastomas and benefit other patients in the future.

Clinical Trial to Assess the Safety and Efficacy of AloCELYVIR With Newly Diagnosed Diffuse Intrinsic Pontine Glioma (DIPG) in Combination With Radiotherapy or Medulloblastoma in Monotherapy

The aim of this study is to assess the safety and efficacy of AloCELYVIR, which consist in bone marrow-derived allogenic mesenchymal stem cells infected with an oncolytic Adenovirus, ICOVIR-5. It has recently been proven that this type of cells are able of transporting oncolytic substances to tumor targets that are difficult to reach, such as medulloblastomas and gliomas, youth cancers located in the cranial cavity that have a poor prognosis and a fatal outcome. In addition, to exerting an anti-tumor action, this virus has the ability to stimulate the immune response, making the therapy even more effective. Thus, the diffuse intrinsic pontine glioma and the medulloblastoma in relapse/progression have been chosen to study the potential of this new advanced therapy through a weekly infusion for 8 weeks.
