Clinical, Laboratory, and Epidemiologic Characterization of Individuals and Families at High Risk of Melanoma
This study will investigate how genetic and environmental factors contribute to the development of melanoma, a type of skin cancer, and related conditions. Individuals >=4 weeks with a personal or family history of melanoma or atypical spitzoid/Spitz tumor may be eligible for this study. Participants will: - Fill out one or two questionnaires about their personal and family medical history. - Provide written consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with melanomas, tumors, cancer, or other related illnesses for whom they are the next-of-kin or legally authorized...

Clinical Relevance of Detecting Molecular Abnormalities in Glial Tumor Exosomes
The purpose of this pilot study is that exosomes constitute a more interesting support for analyzes allowing a broader screening of molecular alterations to be carried out with more reliable, more sensitive and more efficient results than the reference Foundation One Liquid CDx test.

Clinical Safety Study on 5-Aminolevulinic Acid (5-ALA) in Children and Adolescents With Brain Tumors
In this prospective, open, single-armed, multicenter, phase II study for application of 5-ALA in children and adolescents with brain tumors 80 patients will be investigated. Primary objective of the study is to determine the safety of 5-ALA for fluorescence-guided resections in children and adolescents with intra-axial brain tumors. Secondary objectives are - to determine whether fluorescent tissue truly signifies tumor (positive predictive value) in various pediatric brain tumors - to determine the degree of tumor resection on early post-operative MRI - and to determine the pharmacokinetics of 5-ALA in this population.

Clinical Study for the Safety and Therapeutic Efficacy of the AI-QMMM Designed TamavaqTM Personalised Vaccine in Patients With Newly Diagnosed Glioma.
Gliomas are a heterogeneous group of tumors arising from glial cells in the central nervous system and are associated with poor prognosis and significant morbidity. The most aggressive form, glioblastoma multiforme (GBM), remains particularly challenging to treat, often exhibiting resistance to conventional therapies such as chemotherapy and radiation. The average survival for patients with GBM is approximately 15 months, underscoring the urgent need for novel therapeutic strategies that can improve outcomes. Malignant gliomas are the most common primary brain cancer diagnosed and still carry a poor prognosis despite aggressive multimodal management. Despite the continued...

Clinical Study of Carbon Ion Radiotherapy for High-grade Glioma
The objective is to use the advantages of heavy ion physical dosimetry and biology to improve the tumor control rate and long-term survival rate of high-grade glioma, reduce the occurrence of brain tissue radiation damage caused by increasing prescription dose, and provide new treatment suggestions for glioma radiotherapy.

Clinical Study of Fianlimab in Combination With Cemiplimab Versus Pembrolizumab in Adolescent and Adult Patients With Previously Untreated Unresectable Locally Advanced or Metastatic Melanoma
This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called REGN2810, also known as cemiplimab (each individually called a "study drug" or called "study drugs" when combined). The study is focused on patients with a type of skin cancer known as melanoma. The aims of the study are to see how effective the combination of fianlimab and cemiplimab are in treating the melanoma skin cancer, in comparison with a medication, pembrolizumab, approved for the treatment of melanoma skin cancer in adults, and to observe any similarities, or differences, in how the study drugs work in adolescent...

Clinical Study of Oncolytic Virus in Glioblastoma
This clinical trial aims to evaluate whether an oncolytic viral agent can treat recurrent glioblastoma. It will also assess the safety and tolerability of the oncolytic viral agent. The primary question it seeks to answer is: What medical problems do participants experience when injected with the oncolytic viral agent? Researchers will administer the oncolytic viral agent via intratumoral injection to determine its efficacy in treating recurrent glioblastoma. Participant Procedures: Receive the initial injection, followed by additional injections every 2 weeks for a total of 6 injections. Undergo physical examinations and tests every 2 to 4 weeks. Record their...

Clinical Study of QH104 Cell Injection for the Treatment of Meningeal Metastases of B7H3+ Solid Tumors
This is an open, single-arm, single-center, interventional clinical study. It is planned to enroll 3-6 patients with meningeal metastases from B7H3+ solid tumors and to explore, on a small scale, the efficacy of local injection of allogeneic B7H3 CAR-γδ T cells (3*107/dose) for the treatment of patients with meningeal metastases from B7H3+ solid tumors.

Clinical Study on the Safety and Efficacy of TS-2021 in the Treatment of Recurrent Malignant Glioma
The goal of this clinical trial is to evaluate the safety and efficacy of oncolytic virus TS-2021 in the treatment of recurrent malignant glioma.About 30 eligible participants with recurrent malignant glioma will : - Be intratumoral injected the TS-2021 oncolytic virus to study its safety and efficacy. - Be followed for 1 year after the injection to complete imaging studies, neurological function tests, and report adverse events. Using the data obtained during the follow-up period, researchers will conduct statistical analyses and evaluate the safety and efficacy of oncolytic virus TS-2021.

Clinical Trial Evaluating Safety of 5-Aminolevulinic Acid (5-ALA) Combined With CV01 Delivery of Ultrasound for Sonodynamic Therapy (SDT) in Patients With Newly Diagnosed High-Grade Glioma (HGG) Prior to Resection and Standard Adjuvant Therapy (ALA SDT GLIOMA 401)
This trial is designed to evaluate safety and explore possible efficacy of 5-aminolevulinic acid hydrochloride (5-ALA HCl, Gliolan®) with CV01 delivery of ultrasound for sonodynamic therapy in patients with newly diagnosed high-grade glioma prior to resection and standard adjuvant therapy. The study will accrue 10 evaluable high-grade glioma patients. Patients who qualify will receive sonodynamic therapy (5 ALA combined with CV01-delivered sonication) 2 to 5 days prior to standard resection, with one study magnetic resonance imaging being performed between sonodynamic therapy and resection. Resection will be followed by standard radio-/chemotherapy. All patients will be followed...
