Evaluating Biomarkers of Cognitive Dysfunction in Patients With Cancer

This study investigates the effects of brain radiotherapy on cognitive function by evaluating plasma biomarkers and apolipoprotein E (APOE) genotype in patients with primary or metastatic brain tumors. Standard brain radiotherapy is known to impact cognitive outcomes, yet the underlying biological mechanisms remain unclear.

The METAMAX Study: MT027 Allogeneic CAR-T for Brain Metastases From Advanced Solid Tumors

This is a prospective, open-label, multicenter, single arm Phase II trial to evaluate the safety, tolerability, intracranial efficacy, pharmacokinetics, and pharmacodynamics of MT027 administered ICV in patients with B7-H3-positive brain metastases from advanced solid tumors. The trial consists of two sequential stages: a safety run-in stage followed by a dose expansion stage. Approximately 40 participants are planned for enrollment, including approximately 3 to 6 participants in the safety run in stage and 34 participants in the dose expansion stage. The final number of participants enrolled may vary depending on the safety findings observed during the safety run-in stage. Approximately 3 to 6 eligible participants from the primary target population will receive MT027 3×107 CAR+ T cells via ICV injection on Days 1 and 15 of each 28-day cycle. DLTs will be assessed during a 28-day DLT observation period following the first dose. Following SRC confirmation of acceptable safety during the safety run-in stage, an additional 34 participants will be enrolled to evaluate the intracranial efficacy of MT027 dosed at 3×107 CAR+ T cells.

A Phase 1/1b Study of IAM1363 in HER2 Cancers

This is a Phase 1/1b open-label, multi-center dose escalation and dose optimization study designed to evaluate the safety and preliminary efficacy of IAM1363 in participants with advanced cancers that harbor HER2 alterations.

A First-In-Human, Phase 1 Study Evaluating Oral TACC3 PPI Inhibitor, AO-252, in Advanced Solid Tumors With or Without Brain Metastases

The purpose of this study is to assess the safety, tolerability and efficacy of the study drug AO-252 and identify the best dose for use in future studies.

Phase 2b Imaging Study of RAD101 in Participants With Suspected Recurrent Brain Metastases

This is an open-label, single dose, single arm, multicenter Phase 2b study to establish the imaging performance of RAD101 PET in participants who are ≥ 18 years of age and with suspected recurrent brain metastases from solid tumors. The study consists of a 4-week Screening Period, a 3-day Imaging and Safety Follow-Up Period, and a Data Collection Period of up to 6 months. Participant eligibility will be determined during the Screening Period and eligible participants will be enrolled in the study. On Day 1, the enrolled participants will receive a single dose of the investigational medicinal product (IMP), RAD101. Participants will then proceed with a whole brain PET scan. A high-resolution Magnetic Resonance Imaging (MRI) will be performed in joint acquisition with PET or separately on the same day, or on the day prior to or the day following RAD101 administration. For applicable study sites where PK samples will be collected, whole body PET scans will be performed, blood samples will be drawn, and urine will be collected throughout the scanning period. A phone follow-up will be performed on Day 3 (+ 1 day). Participants will have follow-up (longitudinal) MRI (otherwise CT) scans (longitudinal imaging) and/ or a biopsy according to their Standard of Care (SoC). The longitudinal image results, and details of the biopsy if performed as part of SoC (i.e., location and histopathology results), will be collected during the 6- month Data Collection Period.

Phase 1/2 Study Evaluating the Safety, PK/PD, and Clinical Activity of Oral JBI-778 in Patients With Brain Metastases, Leptomeningeal Disease, or Recurrent High Grade Glioma

This is a Phase 1/2, multicenter, open-label, dose-escalation and dose-expansion study evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), cerebrospinal fluid penetration, and preliminary antitumor activity of orally administered JBI-778, a selective PRMT5 inhibitor, in patients with brain metastases, leptomeningeal disease, or recurrent high-grade glioma. The study consists of a dose-escalation phase to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D), followed by expansion cohorts to evaluate preliminary efficacy at the RP2D.

Comparison of the Therapeutic Effects of Methylprednisolone and Dexamethasone on Peritumoral Edema During Radiotherapy for Brain Metastases:

This study is a multicenter, open label, randomized controlled, adaptive phase II/III seamless design clinical trial aimed at comparing the efficacy and safety of methylprednisolone (MP) and dexamethasone (DEX) in the treatment of peritumoral edema in patients with brain metastases during radiotherapy. The research plan includes brain metastasis patients aged 18-75 years, with KPS scores of 40-80, who plan to undergo whole brain radiotherapy or stereotactic radiotherapy. They will be randomly divided into MP group (40-60 mg/day) or DEX group (8-12 mg/day) in a 1:1 ratio, and medication will be continued until the end of radiotherapy, followed by gradual reduction and cessation within one week. The study is divided into two stages: the first stage (stage II exploration) includes 120 cases to preliminarily evaluate the efficacy and safety, and provide a basis for re estimating the sample size in the second stage; The second stage (Phase III confirmation) will expand the sample size based on the results after analysis during the transition period, with a total sample size of no more than 400 cases. The primary endpoint was the change in KPS score and the incidence of grade ≥ 2 hormone related adverse reactions within one week after radiotherapy. Secondary endpoints include cerebral edema index, cognitive function, quality of life, radiotherapy interruption rate, neurotoxicity, survival, and serum biomarkers (IL-6, S100B). The study is supervised by an independent data security monitoring committee and uses statistical methods such as stratified block randomization and mixed effects models to ensure the scientific and ethical compliance of the data. This study is expected to provide high-level evidence-based basis for hormone selection during the perioperative radiotherapy period for patients with brain metastases, and optimize clinical practice.

SMART Trial: Cognitive Sparing Brain Radiotherapy for Multiple Brain Metastases

The goal of this phase II randomized trial is to determine if Stereotactic Radiosurgery (SRS) or Cognitive Sparing WBRT (CS-WBRT) better preserves neurocognitive function than standard Hippocampal Avoidance WBRT (HA-WBRT) in patients with multiple brain metastases ( $\\ge6$ lesions). The main questions it aims to answer are: * Which treatment best preserves cognitive function (memory and executive tasks) at 6 months post-intervention? * Can sparing the left hippocampus and corpus callosum (CS-WBRT) or using focal SRS reduce cognitive decline compared to bilateral sparing? Comparison Groups Researchers will compare three arms to evaluate their impact on cognition and disease control: * Arm A (SRS): Focal high-dose radiation (15-20 Gy in 1 fraction) to intracranial lesions. * Arm B (CS-WBRT): Whole-brain radiation (30 Gy in 10 fractions) sparing the left hippocampus and corpus callosum plus Memantine. * Arm C (HA-WBRT): Whole-brain radiation (30 Gy in 10 fractions) with bilateral hippocampal avoidance plus Memantine. Participant Tasks Participants will: * Complete neurocognitive and neuropsychological tests (HVLT-R, TMT, COWAT, CANTAB) at baseline and follow-up. * Undergo contrast-enhanced brain MRI for planning and tracking tumor progression. * Take Memantine HCL daily for 24 weeks if assigned to the WBRT arms (B or C). * Provide blood samples for biomarker and genetic analysis (e.g., APOE, Tau). * Undergo olfactory function testing and complete quality-of-life questionnaires.
