Researchers are evaluating the use of three-dimensional magnetic resonance elastography (3D MRE) to measure the stiffness and adhesion of meningioma tumors before surgery. This study aims to see if these MRE measurements can predict what surgeons will find during tumor removal and how the tumor's characteristics relate to its behavior and pathology. The goal is to improve surgical planning and risk assessment for patients with meningioma, a common type of brain tumor. Participants will receive a standard brain MRI along with a 3D MRE scan using a 60 Hz vibration frequency to create detailed maps of tumor stiffness and adhesion. These imaging results will be shared with the surgical team to help guide the operation. During surgery, doctors will carefully assess the tumor's stiffness, adhesion, blood supply, and difficulty of removal using a standardized scale. The study will then compare these intraoperative findings with the MRE data and the tumor's pathology after surgery. About 300 patients scheduled for meningioma removal will take part. They will undergo imaging tests before surgery, and their tumors will be evaluated during and after surgery. Researchers will collect information on tumor characteristics, surgical challenges, and histological features. The study will analyze how well preoperative MRE predicts tumor behavior and surgical outcomes, aiming to support MRE as a noninvasive tool for better surgical decisions and improved patient care.

Researchers are investigating a new, non-invasive way to predict the hepatic venous pressure gradient (HVPG) to better manage portal hypertension in people with cirrhosis. This study focuses on comparing two imaging techniques: three-dimensional magnetic resonance elastography (3D-MRE) and two-dimensional magnetic resonance elastography (2D-MRE), aiming to establish a risk system to guide personalized treatment for portal hypertension associated with cirrhosis. Cirrhosis and portal hypertension pose significant health risks, and current gold standard diagnostic methods like HVPG are invasive and less practical for routine use. The study uses 3D-MRE and 2D-MRE imaging performed on a 3.0-Tesla MRI system to measure liver tissue properties. These imaging studies are done within one month before HVPG measurements, which are conducted by trained interventional radiologists following standard procedures. The goal is to see how well these imaging methods predict portal hypertension and cirrhosis severity compared to the invasive HVPG measurement. Participants will undergo both types of MRI elastography scans and HVPG testing. Researchers will assess the accuracy of 3D-MRE and 2D-MRE features over a 12-month period to determine their usefulness in evaluating portal hypertension. The study involves clinical evaluations, imaging assessments, and monitoring of patients' liver health to develop a reliable, less invasive tool for managing cirrhosis and portal hypertension.

Researchers are evaluating anti-HER2-CAR-T cell therapy in patients aged 18 to 70 with HER2-positive locally advanced or metastatic solid tumors, including breast, gastric, colorectal, and pancreatic cancers. This Phase 1, single-center, open-label study aims to assess the safety and effectiveness of this treatment in patients who have not responded to or cannot tolerate conventional therapies. Participants must have measurable tumors, adequate organ function, and an expected survival of at least 12 weeks. Participants receive a single intravenous infusion of anti-HER2-CAR-T cells at doses of 1x10^6, 3x10^6, or 1x10^7 CAR-positive cells per kilogram. Additional infusions may be given at the investigator's discretion. Before treatment, patients undergo screening, peripheral blood mononuclear cell collection, possible bridging therapy, and lymphocyte clearance. The study follows a 3+3 dose escalation design to determine safe dosing. Throughout the study, participants are closely monitored for dose-limiting toxicities within 21 days after infusion. Researchers evaluate treatment safety and effectiveness by assessing tumor response, organ function, and adverse events. The study includes regular clinical assessments, laboratory tests, and imaging to track progress and ensure patient safety. Total participation length depends on treatment and follow-up schedules determined by the study team.

Researchers are investigating HMPL-506, an oral drug, in a Phase 1 clinical study for patients with hematological malignancies such as relapsed or refractory acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), and multiple myeloma (MM). The study has two phases: dose escalation and dose expansion, aiming to determine the safest and most effective dose. Approximately 60 to 132 patients are expected to participate, including those with specific genetic mutations or rearrangements related to these blood cancers. In the dose escalation phase, patients receive increasing doses of HMPL-506 orally once daily in 28-day cycles to identify the maximum tolerated dose and recommended Phase 2 dose. Initial doses start at 50 mg daily, with potential escalation based on safety and efficacy data. The dose expansion phase enrolls patients into three cohorts based on disease type and genetics, treating them with the recommended dose in 28-day cycles until disease progression, intolerable side effects, or other defined reasons to stop. Participants will undergo regular safety monitoring, including evaluation of dose-limiting toxicities, serious adverse events, and response to treatment. Tumor response is assessed every cycle for the first six cycles and then every two cycles thereafter, with follow-up lasting up to 42 months. Additional assessments include bone marrow biopsies, laboratory tests, and performance status evaluations. The study tracks participants until disease progression, withdrawal, or study completion to evaluate HMPL-506's safety and preliminary effectiveness.
