NCT07685301

Development and Validation of an AI Foundation Model for CNS Tumor Classification

This is a multi-center, retrospective, observational study to develop and internally validate an artificial intelligence (AI) foundation model for hierarchical classification of central nervous system (CNS) tumors using approximately 20,000 hematoxylin and eosin (H\&E) whole-slide images (WSIs) collected at Huashan Hospital Fudan University and Shandong Provincial Hospital. Archived pathology slides and linked de-identified clinical, histopathological, and molecular diagnostic data from patients who underwent neurosurgical tumor resection or biopsy between January 1, 2010 and December 31, 2025 will be retrospectively analyzed. The study aims to train and evaluate weakly supervised multiple-instance learning models using pathology foundation models and conventional convolutional neural network feature extractors to predict tumor category, tumor family, terminal WHO 2021 CNS tumor diagnosis, and selected molecular alterations directly from routine H\&E slides. Internal model validation will be performed using patient-level training, validation, and hold-out test datasets. Secondary analyses include comparison of model architectures, virtual molecular profiling, interpretability analyses using attention heatmaps, and comparison of AI-assisted versus pathologist-only diagnostic performance on selected internal test cases.

Loc3CAR: Locoregional Delivery of B7-H3-CAR T Cells for Pediatric Patients With Primary CNS Tumors

Loc3CAR is a Phase I clinical trial evaluating the use of autologous B7-H3-CAR T cells for participants ≤ 21 years old with primary CNS neoplasms. B7-H3-CAR T cells will be locoregionally administered via a CNS reservoir catheter. Study participants will be divided into two cohorts: cohort A with B7-H3-positive relapsed/refractory non-brainstem primary CNS tumors, and cohort B with diffuse midline gliomas (DMG). Participants will receive four (4) B7-H3-CAR T cell infusions over a 4 week period. The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give patients with primary brain tumors. Primary objectives * To determine the safety, maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) for the locoregional delivery of autologous B7-H3-CAR T cells in patients ≤ 21 years of age with recurrent/refractory B7-H3+ primary CNS tumors (Cohort A) or DMG (Cohort B). Secondary objectives * To assess the efficacy, defined as sustained objective response, a partial response (PR) or complete response (CR) observed anytime on active treatment with B7-H3-CAR T cells in patients with relapsed/refractory B7-H3+ primary CNS tumors (Cohort A) or DMG (Cohort B). * To characterize and monitor neurologic toxicities in patients while on study (Cohort A and B).

Study of Abemaciclib and Elacestrant in Participants With Brain Metastasis Due to ER+/HER-2- Breast Cancer

This is a multi-site, global, open-label study that includes a phase 1b evaluation of elacestrant in combination with abemaciclib in women and men with brain metastases from estrogen receptor (ER)-positive, human epidermal growth factor receptor-2 (HER-2) negative breast cancer. Phase 1b was designed to select the recommended phase 2 dose (RP2D) and is followed by an ongoing phase 2 evaluation of elacestrant in combination with abemaciclib in participants with active brain metastases from ER-positive, HER-2 negative breast cancer.

B7-H3.CD28Z.CART in CNS Neoplasms

The purpose of this research study is to test the safety and effectiveness of a cell therapy at different doses for children and young adults with recurrent or progressive brain tumors. Recurrent/recurred means a tumor that has gone away and then came back. This cell therapy is called B7- H3.CD28Z.CART, referred to as B7-H3 CAR T cells. B7-H3 is a protein that is over-expressed on many tumor cells, making it a good target for cancer cell therapy. The names of the study investigational therapies involved in this study are: * Fludarabine (a type of chemotherapy) * Cyclophosphamide (a type of chemotherapy) * B7-H3 CAR T cells (a type of cellular therapy)

Phase I Study of Oral ONC206 in Recurrent and Rare Primary Central Nervous System Neoplasms

The primary objective of this Phase 1, open-label, dose-escalation, and exploratory study is to evaluate the safety and tolerability profile (establish the maximum-tolerated dose) and evaluate the occurrence of dose-limiting toxicities (DLTs) following single weekly or multiple-day weekly dose regimens of single-agent, oral ONC206 in patients with recurrent, primary central nervous system (CNS) neoplasms.
