New glioblastoma trial testing immune drug plus radiation
This Phase 1 study tests whether adding an immune therapy called retifanlimab to radiation (and a chemotherapy medicine called temozolomide, in some parts of the study) is safe and helpful for newly diagnosed glioblastoma patients after surgery with carmustine wafers. It aims to see how well this combination controls the cancer and what side effects are expected.
Baltimore, MarylandAges 18–100 - NCT05082961Recruiting
Blood immune markers and brain radiation after head/neck surgery
This study looks at immune system signals in your blood during and after postoperative radiation therapy for certain head and neck cancers involving the brain or skull base. Researchers want to see whether these “immune markers” relate to treatment response or side effects.
CaenAges 18 years+ - NCT05084430RecruitingPhase 1/Phase 2
Pembrolizumab plus M032 for recurrent brain tumors
This early-phase study tests the safety and early signs of benefit of combining pembrolizumab with M032 in people with certain aggressive brain tumors. You may be considered if you have a glioma tumor that can potentially be removed by surgery.
Birmingham, AlabamaAges 18 years+ - NCT05085028RecruitingPhase 3
Lower-dose pembrolizumab for lung cancer after 6 months
This trial studies whether giving pembrolizumab less often can work just as well for advanced non-small cell lung cancer after you’ve already had 6 months of treatment and are still benefiting. It may help reduce how often you need treatment while keeping cancer control.
BournemouthAges 18 years+ - NCT05086614RecruitingPhase 3
Thymosin-alpha 1 after surgery for high-risk colon cancer
This trial looks at whether thymosin-alpha 1, an immune-support treatment, can help prevent colon cancer from coming back after surgery. It targets people with high-risk stage II or III colon cancer who have had the tumor removed.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05086692RecruitingPhase 1/Phase 2
Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.
San Diego, CaliforniaAges 18 years+ - NCT05088187Recruiting
Study of thinking and quality of life after thyroid surgery
This study looks at how thyroid surgery affects thinking (cognition) and day-to-day quality of life. It may help patients and doctors understand what to expect and how to support people after surgery.
StockholmAges 18 years+ - NCT05088395Recruiting
Blood tests to track cancer signals after treatment
This study measures “circulating tumor markers,” meaning substances from cancer that can show up in blood, to better understand how cancer is doing after treatment. You may join if you recently received cancer care at a participating center and meet basic study and follow-up requirements.
ParisAges 18 years+ - NCT05088798RecruitingPhase 2
PET/MRI scan to help plan surgery for hyperinsulinism
This Phase 2 study uses special PET/MRI imaging to better understand a cause of hyperinsulinemic low blood sugar and guide whether surgery may help. It may help doctors choose the safest plan to reduce severe episodes and protect the brain.
St Louis, MissouriAges Any age - NCT05091255Recruiting
Cold therapy for desmoid tumors in adults
This trial tests whether “cold therapy” (cryotherapy) can shrink or control desmoid tumors. It may help adults whose tumors are located in certain body areas where cryotherapy is considered safe.
Bologna, BOAges 18 years+ - NCT05091372RecruitingPhase 2
Maintenance treatment after transplant for newly diagnosed myeloma
This trial tests whether using belantamab mafodotin plus lenalidomide as long-term maintenance after an autologous stem cell transplant can keep multiple myeloma under control, guided by minimal residual disease (MRD). MRD is a very small amount of disease that may remain after transplant, and the study helps see if treating those patients better improves outcomes.
Houston, TexasAges 18 years+ - NCT05092373RecruitingPhase 1
Tumor treating device plus targeted or immune drugs for advanced cancers
This Phase 1 study tests whether a tumor treating fields device works better when added to standard cancer drugs. It may help people with advanced solid tumors in the chest or belly, especially when standard treatment didn’t work or can’t be tolerated.
Houston, TexasAges 18 years+ - NCT05093153Recruiting
Registry for adults with IgM blood protein conditions
This study is a registry that collects information about adults with certain IgM-related blood conditions. It may help doctors better understand these illnesses and improve future care.
Mérida, BadajozAges 18 years+ - NCT05093335RecruitingEarly Phase 1
PET scan test for CXCR4 in many relapsed cancers
This early study tests a new PET scan tracer (a radioactive imaging agent) that may light up a cell marker called CXCR4 in certain blood and solid tumor cancers. It may help doctors see where cancers are and how much CXCR4 they have, which could guide future treatments.
New York, New YorkAges 18 years+ - NCT05093907RecruitingPhase 1/Phase 2
Testing a new cancer drug plus capecitabine for metastatic colon cancer
This trial studies whether BEY1107, a new treatment, is safe and works better when combined with capecitabine in people with metastatic colorectal (colon/rectum) cancer. It is aimed at cancers that have already progressed after standard chemotherapy.
Seoul, Jongro-goAges 19 years+ - NCT05093231RecruitingPhase 2
Pembrolizumab plus olaparib for stage 4 pancreatic cancer
This trial tests whether combining pembrolizumab (an immunotherapy) with olaparib (a DNA-repair drug) can work better for people with metastatic (stage 4) pancreatic cancer. It targets tumors with certain lab marker results and aims to improve control of cancer growth.
MelbourneAges 18 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT05095207RecruitingPhase 1/Phase 2
Abemaciclib and bicalutamide for HER2-negative metastatic breast cancer
This Phase 1/2 trial tests whether combining abemaciclib with bicalutamide can slow or shrink HER2-negative, androgen receptor–positive (AR-positive) metastatic breast cancer. It mainly looks at safety and side effects, and also whether the combination can help patients with this type of breast cancer.
New York, New YorkAges 18–90 - NCT05095714Recruiting
Fast MRI for close monitoring of high-risk liver cancer
This trial studies a faster MRI scan to help track early liver cancer in people who have cirrhosis and are considered high risk. It may improve how often and how well doctors can look for changes without using longer imaging sessions.
BondyAges 18 years+ - NCT05097274Recruiting
PET-CT scan for men with prostate cancer and a DNA repair mutation
This study uses a special scan (FCH-PET-CT) to help doctors see prostate cancer more clearly in men who have a known gene change involved in DNA repair. It’s meant to improve staging and assessment, especially around when imaging is needed.
London, Sutton, SurreyAges 18 years+ - NCT05096923Recruiting
Research study for young people with cancer and survivors
This study follows children, teens, and young adults with cancer and people who have completed treatment. It aims to better understand cancer care over time and what affects outcomes, which may help improve future treatment and follow-up.
Chapel Hill, North CarolinaAges 1–39 - NCT05097820Recruiting
Study of silicone gel testicular implants after placement
This is an observational study that follows people who receive silicone gel-filled testicular implants. It aims to collect real-world information about safety and healing to help improve future care.
Ghent, East-FlandersAges birth–110 years - NCT05097625Recruiting
Testing early detection of head and neck cancer relapse
This study aims to find signs of head and neck cancer coming back early, using scans/tests after you’ve had radical treatment. If you’re at higher risk and HPV-negative, this may help doctors catch relapse sooner.
LondonAges 18 years+ - NCT05098119RecruitingPhase 2
Study drugs before surgery for mouth or throat cancer
This Phase 2 trial tests giving the immunotherapy drug sintilimab before surgery, along with fewer chemotherapy cycles. The goal is to shrink or control oral or throat squamous cell cancers while keeping side effects lower, before the tumor is removed.
