Recruiting studies
- NCT06896110Enrolling by invitationPhase 1
Spinal chemo and immunotherapy for recurrent high-grade glioma
This trial tests a combination of two drugs—azacitidine and nivolumab—given directly into the spinal fluid for people whose high-grade glioma has come back after initial treatment. The goal is to see if this approach can safely target the tumor and slow its growth.
Iowa City, IowaAges 13 years+ - NCT03942328RecruitingPhase 1/Phase 2
Immune cell vaccine plus checkpoint treatment after liver radiation
This trial tests a combination of a personalized immune cell treatment (made from your own cells) and a pneumococcal vaccine along with an “immune checkpoint” drug after high-dose radiation for certain unresectable liver cancers. The goal is to help your immune system better attack the cancer and to see how safe and effective this approach is.
Rochester, MinnesotaAges 18 years+ - NCT06660056RecruitingPhase 1
GC001 injection for returning or growing high-grade brain tumors
This trial tests a new drug, GC001, injected directly into the tumor in people with high-grade gliomas (WHO grade 3 or 4) that have come back or are growing. It may be an option if standard treatments have stopped working.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06018363RecruitingPhase 1/Phase 2
Cell therapy for recurrent high-grade glioma
This trial tests a new cell therapy (QH104) for people with an aggressive brain tumor called high-grade glioma that has come back or worsened after standard treatment. The therapy targets a specific protein (B7-H3) on tumor cells to try to fight the cancer.
Suzhou, JiangsuAges 18–70 - NCT06471738RecruitingPhase 2
Targeted drug combo for untreated follicular lymphoma
This trial tests a combination of three targeted drugs (zanubrutinib, rituximab, and venetoclax) for people with untreated follicular lymphoma. The goal is to see if this combination works better than standard treatments and has manageable side effects.
BeijingAges 18 years+ - NCT05979064Recruiting
Belly fat graft for recurrent brain tumor
This study tests if a piece of your own belly fat (omentum) placed in the brain during tumor surgery can help fight recurrent glioblastoma. It is for people who are already scheduled for surgery to remove their brain tumor.
New York, New YorkAges 18 years+ - NCT07179328RecruitingPhase 1
Focused ultrasound for glioblastoma during standard chemo
This trial tests whether focused ultrasound can safely open the blood-brain barrier to help your chemotherapy work better. It is for people with glioblastoma who have already completed standard surgery and chemo-radiation and are now on maintenance chemo.
Toronto, OntarioAges 18–85 - NCT07544992RecruitingPhase 1
CAR T Cells for Recurrent High-Grade Brain Tumors
This trial tests genetically engineered immune cells (CAR T cells) injected directly into the brain to treat recurring or worsening high-grade gliomas. The cells are designed to recognize and attack tumor cells that have specific markers (EGFR and IL13Rα2).
Duarte, CaliforniaAges 18 years+ - NCT05945329Recruiting
New scar-wrap to treat painful tightness after breast implants
This trial tests a medical mesh/scaffold (GalaFLEX LITE™) used during revision surgery to help treat capsular contracture, where scar tissue tightens around a breast implant. It may improve comfort and the appearance of the breast after implant augmentation problems.
Scottsdale, ArizonaAges 22–70 - NCT03896568RecruitingPhase 1
Trial of stem cell therapy for recurrent high-grade brain tumors
This Phase 1 study tests an advanced stem-cell treatment (hMSC-DNX2401) for recurrent high-grade glioma, including certain brain tumor types that come back. It aims to see if the treatment can be safely delivered and whether it can help control the tumor after standard therapies have already been tried.
Houston, TexasAges 18 years+ - NCT04299191RecruitingPhase 1/Phase 2
LAM561 for children with advanced brain or solid tumors
This Phase 1/2 study tests a medicine called LAM561 in children whose cancer is advanced and not responding to standard treatment. The goal is to see if the drug is safe and can shrink or control tumors in this setting.
Little Rock, ArkansasAges Up to 18 years - NCT04543201Recruiting
Telehealth help planning your future care after high-grade brain cancer
This trial offers video visits to help people newly diagnosed with a high-grade glioma (a serious brain tumor) talk through their future care preferences. It aims to support “advanced directives,” meaning documenting the kind of care you want if you can’t speak for yourself later.
Rochester, New YorkAges 18 years+ - NCT05030298RecruitingPhase 1
Pre-op focused radiation for aggressive brain tumor
This early-phase study tests a type of very targeted radiation given before surgery for people with a high-grade (aggressive) brain tumor. The goal is to see if this approach is safe and potentially improves treatment, while collecting tumor and blood samples for research.
Phoenix, ArizonaAges 18 years+ - NCT05096481RecruitingPhase 2
Vaccine trial for children with certain brain tumors
This Phase 2 study tests a vaccine made to target CMV (a virus) in order to treat children with medulloblastoma or newly diagnosed high-grade glioma/DIPG. If you’re eligible, you’d receive the study vaccine and the team would closely watch how well it’s tolerated and how your cancer responds.
Aurora, ColoradoAges 3–39 - NCT05532397Recruiting
Tested lab-chosen drug combo for recurrent brain tumor
This study uses a patient’s tumor tissue to test drug combinations in the lab, aiming to help choose a better second-line treatment for recurrent high-grade astrocytic glioma. If your tumor tissue can be tested, the results may guide a more personalized medication plan.
SingaporeAges 21–99 - NCT05698524RecruitingPhase 1
Temodar plus an investigational pill for recurrent brain cancer
This Phase 1 study tests an investigational drug (PCI-24781) together with Temodar in people whose high-grade glioma (grade III/IV) has come back after prior treatment. It aims to find a safe dose and see how well the combination may work for recurrent disease.
Omaha, NebraskaAges 19 years+ - NCT05954858Recruiting
Surgical flap to help treat glioblastoma by bypassing the blood-brain barrier
This trial tests a surgical technique that places a tissue flap near a glioblastoma surgery site to help medicines reach the brain more effectively. You might be considered if you are planning major brain tumor surgery and meet specific health, imaging, and lab requirements.
New York, New YorkAges 18 years+ - NCT06011109RecruitingPhase 1/Phase 2
APG-157 plus Avastin for recurrent high-grade glioma
This trial tests a combination of two drugs—APG-157 (an oral plant-based medicine) and bevacizumab (Avastin)—for people with recurrent high-grade brain tumors that have already been treated with standard therapies. The goal is to see if adding APG-157 can help control the tumor better.
Rochester, MinnesotaAges 19 years+ - NCT06172595RecruitingPhase 2
PET scan to tell tumor growth from treatment effects in brain cancer
This trial tests whether a special PET scan can tell the difference between actual tumor growth and treatment-related changes in people with aggressive brain cancer (high-grade glioma). If you have had radiation and an MRI shows a growing lesion, this study may help clarify the cause.
SingaporeAges 21 years+ - NCT06630260RecruitingPhase 1/Phase 2
Avutometinib and Defactinib for brain tumors
This trial tests two oral drugs, avutometinib and defactinib, in people with aggressive brain tumors like glioblastoma. The goal is to see if this combination can shrink tumors or stop them from growing.
CambridgeAges 16 years+ - NCT06632236RecruitingPhase 1

Common questions
- Are there clinical trials for high grade glioma (iii or iv)?
- Yes. Clin2 currently lists 1,283 recruiting high grade glioma (iii or iv) studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a high grade glioma (iii or iv) trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a high grade glioma (iii or iv) trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
