StrasbourgAges 18 years+ - NCT05474378RecruitingPhase 1
CAR T cell therapy for recurrent glioblastoma
This early-phase study tests a type of immune-cell treatment (CAR T cells) aimed at a target called B7-H3 in people with glioblastoma or related grade 4 brain tumors that have come back. It’s meant to see if the treatment can shrink the tumor or control the disease and to learn how safe it is.
Palo Alto, CaliforniaAges 18 years+ - NCT05473637Recruiting
Study causes of small vessel brain disease in stroke and memory issues
This trial looks at people who may have “small vessel” problems in the brain, which can cause stroke, memory trouble, walking changes, movement symptoms, or headaches. It may help researchers better understand the genetic and non-genetic causes, which could improve future diagnosis and treatment.
TaipeiAges 18 years+ - NCT05483465RecruitingPhase 4
NAD supplement trial for brain blood vessel health in aging
This trial studies whether taking an NAD supplement can support brain blood vessel health as people age. Participants will be tested for brain and health changes and may help researchers understand how to keep the brain’s blood vessels healthier over time.
Oklahoma City, OklahomaAges 60–85 - NCT05432804RecruitingPhase 1/Phase 2
Selinexor added to temozolomide for recurring brain glioblastoma
This trial studies whether adding selinexor to the standard chemotherapy temozolomide (with radiation) can better treat glioblastoma that has come back after prior treatment. If you meet specific tumor, health, and lab requirements, the goal is to slow tumor growth or improve symptoms.
Phoenix, ArizonaAges 18 years+ - NCT05259605Recruiting
Study uses brain tumor tissue and scans to track treatment outcomes
This is an observational study that collects and compares information from patients with primary brain tumors and their treatment results. It uses stored tumor tissue and brain scans to better understand outcomes using updated tumor classification methods.
InnsbruckAges 18 years+ - NCT05426967Recruiting
Brain stimulation for depression after mild traumatic brain injury
This trial studies a noninvasive brain treatment (rTMS) to reduce depression symptoms in people with past mild traumatic brain injury from military service. It may help by changing brain activity, while also requiring stable mental health care and regular follow-up.
Palo Alto, CaliforniaAges 18–55 - NCT05435859Enrolling by invitation
Mapping the brain area for speech during surgery
This study uses tiny brain electrodes placed during surgery to better understand how a brain region helps with speech. The results may guide safer brain mapping during surgery for people with epilepsy or brain tumors.
San Francisco, CaliforniaAges 18–70 - NCT05450237Enrolling by invitation
Testing thinking and memory questionnaires in people with brain injury
This study checks how well certain questionnaire and testing tools work for people who have brain damage from neurologic conditions and ongoing brain inflammation. It may help future patients by improving which tests are most accurate and easy to use.
Pozzilli, IserniaAges 18–80 - NCT05452005RecruitingPhase 1
PET scan with a new tracer for lung cancer brain metastases
This Phase 1 study tests whether a specialized PET scan tracer can “light up” metastatic non-small cell lung cancer in the brain. If you join, you’ll get brain MRI and PET/CT scans and you’ll continue with your planned cancer treatments and follow-up imaging.
Sacramento, CaliforniaAges 18 years+ - NCT05423210RecruitingEarly Phase 1
Atezolizumab with pre-surgery brain radiation for glioblastoma
This early-phase study tests atezolizumab (an immune therapy) together with radiation before brain surgery for glioblastoma. It aims to make the treatment safer and more effective before the tumor is removed.
