CD19 CAR-T for adults with hard-to-treat B-cell cancers
This Phase 1 trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell cancers have come back or did not respond to treatment. It may help your immune system better recognize and attack cancer cells, but it is early research, so benefits and risks are still being defined.
Rochester, MinnesotaAges 18 years+ - NCT04892303RecruitingPhase 1
Planning treatment using radiation plus radioactive iodine for thyroid cancer
This Phase 1 study tests how doctors plan a combination of two radiation approaches—external beam radiation and radioactive iodine—for thyroid cancer that is not fully responding to standard treatment. It may help people who still have iodine-avid tumor spots, but whose iodine uptake looks too low to work well with radioactive iodine alone.
Baltimore, MarylandAges 18–85 - NCT04894643Recruiting
Pre-surgery proton radiation plus chemo for borderline pancreatic cancer
This trial tests whether giving proton radiation and chemotherapy before surgery can shrink or control “borderline resectable” pancreatic cancer so it can be removed more effectively. It may help by improving treatment response while planning for surgery afterward.
Wiener Neustadt, Lower AustriaAges 18 years+ - NCT04893564Recruiting
Testing blood DNA after 6 months of Waldenström treatment
This study looks at a blood test called circulating tumor DNA, measured after 6 months of treatment, to see how well it predicts outcomes in people with Waldenström macroglobulinemia. It may help doctors better judge who is responding and who may need treatment adjustments earlier.
AmiensAges 18 years+ - NCT04894188Recruiting
Hormone plus radiation before prostate surgery for high-risk cancer
This trial studies giving hormone treatment and radiation before prostate surgery to treat high-risk, locally advanced prostate cancer. It aims to improve cancer control by shrinking or controlling the tumor before removing it.
Douliu City/Huwei Township, Yunlin CountyAges 20–75 - NCT04894370RecruitingPhase 2
Trial tests immunotherapy plus chemotherapy and radiation for anal cancer
This Phase 2 trial studies a combination of immunotherapy (spartalizumab), chemotherapy (mDCF includes docetaxel), and radiation to treat metastatic or returning anal squamous cell cancer. It may help shrink tumors and improve outcomes compared with standard approaches, but eligibility is strict to keep participants safe.
BesançonAges 18 years+ - NCT04895839Recruiting
Mental health coaching for men with prostate cancer
This study looks at what affects mental health while men with prostate cancer take part in a patient empowerment program. It may help you and others by testing a practical support approach delivered through email, texts, and online videos.
Ghent, East FlandersAges 18 years+ - NCT04895436RecruitingPhase 2
Oral venetoclax plus IV obinutuzumab after prior CLL treatment
This trial tests whether adding oral venetoclax together with an IV antibody called obinutuzumab can control CLL when the disease comes back after a specific prior treatment. It also looks closely at side effects to see what changes in “disease activity” and safety to expect.
La Jolla, CaliforniaAges 18 years+ - NCT04895709RecruitingPhase 1/Phase 2
Testing a new cancer drug for advanced solid tumors
This early-phase trial tests how well a new drug (BMS-986340) works alone and combined with other treatments in people with advanced solid tumors that have progressed despite standard care. It also studies tumor samples to look for biomarkers that may predict who benefits.
Clovis, CaliforniaAges 18 years+ - NCT04896684Recruiting
Study collecting gut health information from adults’ scans
This study is looking at people who need an intestinal scope (endoscopy) for gut symptoms or bowel conditions like IBS, IBD, or possible colorectal cancer. Your results may help doctors better understand these long-term conditions and improve follow-up care.
ToulouseAges 18–99 - NCT04896801Recruiting
MRI-guided radiation for certain prostate cancer risks
This trial tests a precise, MRI-guided radiation treatment given over 7 days for people with prostate cancer in specific risk categories. It may help shrink or control the cancer while carefully targeting the tumor.
BrusselsAges 18 years+ - NCT04897321RecruitingPhase 1
CAR T therapy for children with B7-H3 solid tumors
This early-phase study tests a lab-made immune therapy (CAR T cells) made from your own cells to treat children’s solid tumors that have a specific marker called B7-H3. It is designed for kids whose cancer has come back or did not respond to standard treatment, aiming to shrink tumors and keep the therapy safe.
Memphis, TennesseeAges Up to 21 years - NCT04897490Recruiting
Real-world study of ATO plus ATRA for adult acute APL
This study looks at how well first-time treatment with ATO plus ATRA works in adults with acute promyelocytic leukemia (APL). It mainly checks treatment results in real life, including whether patients reach “molecular remission” (very deep disease control).
La Plata, Buenos AiresAges 18 years+ - NCT04898647Recruiting
Study of blood thickness in Waldenström’s disease
This study looks at “hyperviscosity,” meaning very thick blood, in people with Waldenström macroglobulinemia (WM). Your results may help doctors better understand who needs treatment and what tests should be used, even if thick blood is not found.
AmiensAges 18 years+ - NCT04898790Recruiting
Testing ways to improve thinking after bone marrow transplant
This study looks at whether a physical activity program and related study measures can improve thinking and memory in older adults around the time of a stem cell transplant. If you qualify and participate, the team will compare outcomes between groups to see what approach works best.
Omaha, NebraskaAges 19 years+ - NCT04899908RecruitingPhase 2
Brain radiation with or without gadolinium nanoparticles for brain metastases
This trial tests whether adding tiny gadolinium-containing nanoparticles to standard brain radiation can better control brain metastases from certain cancers. It is for people with tumors that have grown after immunotherapy, are from certain cancers (like melanoma, GI, or HER2+ breast), are cystic, are large, or have come back after prior radiation.
Boston, MassachusettsAges 18 years+ - NCT04900558Recruiting
Study outcomes after robotic bladder removal surgery
This trial follows adults who are planning to have a robotic radical cystectomy (surgery to remove the bladder and surrounding tissue) to learn what outcomes to expect. If you choose to join and meet the basics, it may help your team compare results and improve care for future patients.
Florence, TuscanyAges 18 years+ - NCT04900818RecruitingPhase 1
Givastomig for advanced solid cancers, including gastric and pancreas
This Phase 1 trial tests how safe and effective givastomig (TJ033721) is for advanced or metastatic solid tumors. It may help people whose cancer has grown despite standard treatment, or—if in the combination parts—specific cancers that meet certain lab test and tumor-marker requirements.
Orange, CaliforniaAges 18 years+ - NCT04900623RecruitingPhase 2
Using HPV blood test to guide treatment for HPV throat cancer
This Phase 2 study tests a “risk-adapted” treatment plan for HPV-related throat cancer, using an HPV DNA blood test to help decide how treatment is done. If your baseline blood test shows detectable HPV DNA, the study may help tailor therapy to your risk and potentially improve outcomes while limiting unnecessary treatment.
Boston, MassachusettsAges 22 years+ - NCT04900935Recruiting
Survivorship and palliative care planning for metastatic lung cancer
