Philadelphia, PennsylvaniaAges 22 years+ - NCT05124236Recruiting
Pre-surgery vs post-surgery focused radiation for brain metastases
This trial compares two ways of giving focused radiation for brain metastases: before surgery or after surgery. It aims to see which timing works better to control tumors while keeping you safe.
InnsbruckAges 18 years+ - NCT05116137Enrolling by invitation
Exercise therapy to build muscle after glioblastoma
This trial studies whether a resistance (strength-building) exercise program can help survivors of glioblastoma keep or increase their muscle mass. If you are able to safely exercise, it may support recovery and overall strength after treatment.
Halifax, Nova ScotiaAges 18 years+ - NCT05102747Recruiting
Surgery-like brain radiation for up to 5 metastases
This trial compares two ways of giving focused radiation to the brain for people with a limited number of brain metastases. It aims to see which schedule works best (and is likely best for costs and quality of life).
BordeauxAges 18 years+ - NCT05049148Recruiting
Study platelets in brain and spinal tumors
This study looks at how blood “platelets” may be involved in brain or spinal (medullary) tumors by testing tumor tissue taken during surgery or biopsy. It may help researchers understand disease biology and guide future treatments.
ParisAges 18 years+ - NCT05064280RecruitingPhase 2
Pembrolizumab plus lenvatinib for brain metastases from solid tumors
This Phase 2 trial studies whether combining pembrolizumab with lenvatinib can shrink or control brain metastases in people with triple-negative breast cancer, lung cancer, or other solid tumors. It focuses on patients who have measurable brain lesions that can be followed on MRI.
Houston, TexasAges 18 years+ - NCT05048212RecruitingPhase 2
Nivolumab, ipilimumab, and cabozantinib for kidney cancer brain spread
This Phase 2 study tests how well nivolumab plus ipilimumab, along with cabozantinib, treats untreated or worsening kidney cancer that has spread to the brain. It may help shrink brain tumors and slow the disease when standard local brain treatments aren’t the right option.
Houston, TexasAges 18 years+ - NCT05045950RecruitingPhase 2
Whole brain radiation that aims to protect thinking skills
This Phase 2 trial tests a modified form of whole brain radiation to see if it can better protect thinking and memory in adults with brain metastases. You may join even if you’ve had other cancer treatments before, as long as your situation fits the study rules.
Milwaukee, WisconsinAges 18 years+ - NCT04988009Recruiting
Telemedicine care experience survey for brain tumor patients
This trial asks brain tumor patients and caregivers to share what they think about the quality of care they receive through telemedicine. Your feedback may help improve how neuro-oncology visits are done by video in the future.
Houston, TexasAges 18 years+ - NCT04109131Recruiting
Study platform for brain metastases in solid cancers
This trial studies people with solid tumors that have spread to the brain (including the brain lining) to help researchers learn what works and how best to treat it. You may be asked for blood/tissue samples and a procedure to collect spinal fluid when brain metastases are diagnosed.
AnderlechtAges 18 years+ - NCT04905264Recruiting
Studying factors and care quality after severe brain injury
This study looks at how outcomes and care quality vary for people with serious acquired brain injuries while in a rehabilitation unit. It may help clinicians understand what care works best and why.
AlessandriaAges 18 years+ - NCT04869059Recruiting
tDCS for mild brain injury memory word finding
This trial tests whether a noninvasive brain stimulation treatment (tDCS) can improve word-retrieval problems after a mild or moderate concussion-like brain injury. It may help if testing shows trouble finding the right words when speaking.
Dallas, TexasAges 18–75 - NCT04923542RecruitingPhase 1/Phase 2
Targeted drug plus focused brain radiation for breast cancer
This study tests whether abemaciclib (a targeted pill) given with focused radiation to brain tumors can control hormone receptor–positive, HER2-negative breast cancer in the brain. It’s designed to see if the combination helps shrink or slow the growth of brain metastases while keeping side effects manageable.
Tampa, FloridaAges 18 years+ - NCT04908709Recruiting
MRI-guided proton therapy for high-grade brain tumors in children
This study looks at how metabolism in a child’s brain tumor changes during proton therapy, using special MRI scans. It may help doctors better understand treatment response and tailor care for pediatric high-grade gliomas.
