Recruiting studies
- NCT05259709RecruitingPhase 1
Imaging test to map tumors in cancers on PD-1 therapy

Omaha, NebraskaAges 21–65 - NCT05271240RecruitingPhase 3
Targeted brain-artery drug added to standard treatment for new GBM
This Phase 3 trial tests whether delivering a cancer drug directly into brain blood vessels, along with standard radiation and temozolomide, works better than standard treatment alone in newly diagnosed glioblastoma (GBM). The goal is to improve control of the tumor while comparing side effects between the two approaches.
New York, New YorkAges 18 years+ - NCT05272293RecruitingPhase 1/Phase 2
Immunotherapy using donor immune cells for young people with AML
This trial tests a new cancer treatment made from a close family member’s immune cells, adjusted in the lab and given to children or young adults with AML. It may help the immune system better attack leukemia, especially for high-risk, relapsed, or refractory AML.

Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.
Chicago, IllinoisAges 18 years+ - NCT05295680RecruitingPhase 2
Oral hymecromone for primary sclerosing cholangitis
This trial tests whether taking hymecromone by mouth can improve primary sclerosing cholangitis (a liver/bile duct condition). It may help by targeting inflammation and bile duct problems, especially in people who are stable on other medicines.
Redwood City, CaliforniaAges 14–75 - NCT05297734Recruiting
Study compares two cancer support care plans
This study tests two different ways of providing supportive care for adults with cancer to see which one works better. It may help improve comfort, support, and care coordination during treatment.
Birmingham, AlabamaAges 18 years+ - NCT05298995RecruitingPhase 1
GD2 CAR T-cell treatment for pediatric brain tumors
This trial tests a special immune-cell therapy (GD2 CAR T cells) made for pediatric brain tumor patients. It uses a planned treatment plan and monitoring to see if the therapy is safe and can work against the tumor.
Roma, ItalyAges 6 months–30 years - NCT05303285RecruitingPhase 4
Secukinumab for active ankylosing spondylitis in Chinese adults
This trial studies whether secukinumab (a targeted medicine given by injection) can reduce symptoms and disease activity in adults with active ankylosing spondylitis. You may be considered if other common anti-inflammatory medicines have not worked well enough or you could not take them.
Wuhan, HubeiAges 18–80 - NCT05304286Recruiting
Study of brain and pain in long-lasting post-surgery pain
This trial studies what’s happening in the brain and how pain is processed in people with pain that lasts long after surgery. It may help researchers understand chronic post-surgical pain and find better ways to treat it.
Boston, MassachusettsAges 12 years+ - NCT05305859RecruitingPhase 2
Venetoclax, chidamide, and azacitidine for hard-to-treat AML
This Phase 2 trial tests whether adding three medicines—venetoclax, chidamide, and azacitidine—can help adults whose AML has come back or did not respond to treatment. It may help shrink or control the leukemia and improve outcomes for people who fit the study’s health and lab requirements.
Xiamen, FujianAges 18 years+ - NCT05310591RecruitingPhase 1/Phase 2
Study anti-PD1 treatment with Kymriah re-dosing for leukemia
This Phase 1/2 trial studies giving an anti-PD1 antibody (like pembrolizumab or nivolumab) along with a second Kymriah (tisagenlecleucel) infusion in children and young adults whose B-cell leukemia is coming back or their Kymriah effect has faded. It may help the new immune treatment work better after the first Kymriah.
BordeauxAges 1–25 - NCT05316948Recruiting
Study of mental health and sexuality in teens
This study asks young people in psychiatric care about mental health and sexuality, using their study information to understand how these may relate. You may be able to join whether or not you take psychiatric (mental health) medicines, as long as it doesn’t interfere with urgent/emergency needs.
Vence, Alpes MaritimesAges 15 years+ - NCT05317494Recruiting
Test of venetoclax for AML when intensive chemo isn’t possible
This study looks at how a person’s leukemia “disease state” changes over time for adults with acute myeloid leukemia (AML) who cannot receive the strongest (“intensive”) chemotherapy. It tests using oral venetoclax as a first treatment option, which may help control the disease for people ineligible for intensive chemo.
Pátrai, AchaiaAges 18 years+ - NCT05318417Recruiting
Cochlear implant study for one-sided deafness
This study checks whether cochlear implantation is safe and effective for people who have very poor hearing in one ear (single-sided deafness) while the other ear hears normally or nearly normally. You may be enrolled if you meet specific hearing test and health/surgery readiness requirements.
Palo Alto, CaliforniaAges 5 years+ - NCT05324475Recruiting
Nutritional supplement to support immunity and energy in older adults
This trial tests whether a safe nutrition supplement can help older adults with malnutrition maintain immune function and energy (mitochondrial function). It may support recovery during rehabilitation, but you must meet specific nutrition and health criteria.
Lausanne, SwitzerlandAges 75 years+ - NCT05327933Recruiting
Preventing chronic bleeding from the brain’s covering after surgery
This trial looks at whether a procedure called middle meningeal artery embolization can help stop chronic subdural hematoma (slow bleeding/collection under the brain covering) from coming back after your first surgery. It studies an added endovascular treatment right after your operation to reduce recurrence.

Donor immune cells to help prevent AML return after treatment
This study tests an “immune cell therapy” made from a family donor to help children and young adults with AML stay in remission after chemotherapy. It may help reduce the chance that AML comes back, but eligibility depends on remission status, donor suitability, and avoiding certain infections or liver issues.
Minsk, Minsk OblastAges 6 months–21 years - NCT05336318Recruiting
