NCT03775330
This clinical study is a parallel, prospective observational single-centre trial in patients presenting with 5 to 30 brain metastases. Patients to receive either stereotactic radiosurgery (SRS) alone or SRS plus whole brain radiation (WBRT) will be enrolled.
NCT07462507
Adult patients with primary or secondary central nervous system malignancies will be invited to undergo a baseline \[C-11\]-CS1P1 PET scan and a follow-up scan within 24 months of the baseline scan (preferably within 6-months post-treatment).The study will describe patterns of tracer uptake in tumors and normal brain and explore how these patterns relate to MRI findings, treatments received, and clinical outcomes.
NCT06253871
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.
NCT07248228
Participants in this research study have cancer that has spread to their brain, called brain metastases. One treatment for this type of cancer is called whole brain radiotherapy that stays away from a specific neurocognitive substructure, called the hippocampus, combined with medication to preserve cognitive function. This study compares that approach to another approach of whole brain radiotherapy that stays away from additional structures that are thought to have a role in cognitive function. Researchers want to see if there is a difference in the preservation of cognitive function between these two approaches.
NCT05987644
This study will consist of a Phase 1b and Phase 2 portion. The Phase 1b portion will enroll first followed by the Phase 2 portion. Each cycle of treatment = 28 days. Subjects will receive alectinib twice daily. Those in the Phase 1b portion will receive alectinib alone. Those in Phase 2 Arm A will receive alectinib alone. Those in Phase 2, Arm B will receive SRS + alectinib. A maximum of 25 cycles (2 years) of alectinib may be administered on study.
NCT05703269
This study is designed to see if we can lower the chance of side effects from radiation in patients with breast, kidney, small cell lung cancer, non-small cell lung cancer or melanoma that has spread to the brain and who are also being treated with immunotherapy, specifically immune checkpoint inhibitor (ICI) therapy. This study will compare the usual care treatment of single fraction stereotactic radiosurgery (SSRS) given on one day versus fractionated stereotactic radiosurgery (FSRS), which is a lower dose of radiation given over a few days to determine if FSRS is better or worse at reducing side effects than usual care treatment.
NCT03508752
The phase I component of the study is to identify maximal tolerated dose (MTD). The phase II is to evaluate neurocognitive decline.
NCT07491211
The goal of this retrospective real-world study is to evaluate the effectiveness and safety of first-line osimertinib combined with early intracranial stereotactic radiotherapy (SRT) in patients with EGFR-mutant non-small cell lung cancer (NSCLC) with symptomatic brain metastases. Eligible patients include adults with stage IV EGFR-mutant NSCLC who received first-line osimertinib monotherapy and early intracranial SRT. Data will be extracted from hospital medical records across multiple centers. The primary endpoint is real-world progression-free survival (rwPFS). Secondary endpoints include overall survival (OS), rwPFS2, time to next treatment or death (TTNT), and time to treatment discontinuation or death (TTD). Exploratory endpoints include CNS progression patterns, CNS progression-free survival (CNS PFS), CNS objective response rate (CNS ORR), and incidence of symptomatic CNS radiation necrosis.
NCT04074096
This study evaluates the addition of stereotactic radiosurgery (SRS) to the combination of binimetinib + encorafenib + pembrolizumab in the treatment of BRAFⱽ⁶⁰⁰ mutation-positive melanoma with brain metastases (MBM).
NCT05692635
The purpose of this research is to see if monitoring the brain using magnetic resonance imaging (MRI) after radiation therapy will allow investigators to find cancer that has spread to the brain (brain metastases) before it causes symptoms.
NCT07130786
This is a randomized trial for patients with brain metastases in the primary motor cortex who have not had seizures to receive either the prophylactic anti-seizure medication levetiracetam (also known by its trade name Keppra) or proceed with standard of care management, which does not currently include prophylactic levetiracetam. Patients who enroll to this trial will be randomized to receive prophylactic levetiracetam or not receive prophylactic levetiracetam.
NCT07481786
This is a phase 3, randomized, controlled clinical trial comparing two brain-directed treatment strategies for adult patients with extensive brain metastases from lung adenocarcinoma. The trial compares fractionated stereotactic radiotherapy combined with bevacizumab (FSRT-Bev) versus hippocampus-avoidant whole-brain radiotherapy with simultaneous integrated boost (HA-WBRT-SIB). The main objectives are to evaluate intracranial tumor control and preservation of neurocognitive function . Patients will be randomly assigned in a 1:1 ratio to receive either FSRT plus bevacizumab or HA-WBRT-SIB. In the experimental group, FSRT is delivered to visible brain tumors over 5 daily treatments (total 30 Gy, 6 Gy per fraction). Bevacizumab is given intravenously every 3 weeks for 4 cycles. In the control group, patients receive hippocampus-avoidant whole-brain radiation (25 Gy) with a simultaneous dose boost to metastatic lesions (40 Gy total) over 10 daily treatments.
NCT07464470
GENCONCOR-2 is a translational research aimed to compare the molecular profile of primary tumors and their matched brain metastases in gastroesophageal cancers, including cancer of the esophagus, gastroesophageal junction, and stomach. The study is based on the previously established international GASTROBRAIN cohort (ClinicalTrials.gov ID: NCT07448493), which provides comprehensive clinicopathological and treatment data for over 230 patients. It will be conducted by retrospective analysis of paired samples of histological material (primary tumor and corresponding brain metastasis) with determination of HER2 expression status (IHC ± FISH), MSI status (IHC ± PCR), PD-L1 combined positive score (CPS), and CLDN18.2 expression status (IHC)
NCT05378633
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Therapy options for multiple brain metastases may vary and range from stereotactic radiosurgery (SRS), whole-brain radiotherapy (WBRT), chemotherapy, immunotherapy to palliative best supportive care. Especially the efficacy and toxicity of SRS compared to WBRT in patients with extensive brain metastases (\>4) is not yet clear but of incremental relevance in this seriously ill cohort with a limited life span. These health-impaired patients might especially profit from a less toxic treatment that is also time sparing with 1 or few sessions in SRS versus 10 sessions in WBRT. On the other hand, no compromises in efficacy want to be done.
NCT03368625
This study will be a non-randomized phase II trial for patients with one to six brain metastases, at least one of which is appropriate for surgical resection. Upon registration, patients will be assigned to receive neo-adjuvant stereotactic radiosurgery (NASRS).

NCT05789589
To determine the safety and efficacy of using the drug azeliragon combined with stereotactic radiosurgery. Specifically, to determine if this combination will lead to improved response in the brain (tumor shrinking in size) and overall tumor control (how long tumor remains controlled).
NCT06315010
REPOSE is a phase II clinical trial exploring the safety and efficacy of repotrectinib in patients with non-small cell lung cancer (NSCLC) characterized by the presence of brain metastasis (BM) and whose tumors have mutated ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) gene.
NCT06101069
The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with recurrent tumors, individuals with previously untreated tumors, and healthy individuals who have no brain diseases and have not had radiation treatment to the brain. Participants will undergo an MRI scan at a one-time research study visit; no extra tests or procedures will be required for this research study. The primary objectives of this study are: * To demonstrate the clinical feasibility of combining MRF with state-of-the-art parallel imaging techniques to achieve high-resolution quantitative imaging within a reasonable scan time of 5 min for whole brain coverage. * To apply the developed quantitative approach in combination with IVIM MRI for differentiation of tumor recurrence and radiation necrosis. * To investigate the effect of radiation dose on the development of radiation necrosis and tumor recurrence.
