GrazAges 12 years+ - NCT03819751Recruiting
MRI-guided prostate biopsy: software vs visual matching
This study compares two ways of using prostate MRI images to guide a biopsy and check how accurately prostate cancer can be found. If you have MRI spots that may be cancer, the trial will help test whether computer software or a visual method works better.
Leuven, Vlaams-brabantAges 50–75 - NCT03821246RecruitingPhase 2
Atezolizumab and other drugs before prostate surgery for high-risk cancer
This Phase 2 trial tests whether giving immunotherapy (atezolizumab) plus another drug before surgery can shrink or control high-risk localized prostate cancer. The goal is to improve outcomes by treating the cancer early, before radical prostatectomy.
San Francisco, CaliforniaAges 18 years+ - NCT03823144Recruiting
Imaging small live tumor details during surgery
This study uses a special camera to look at solid tumors from inside the body during an operation. It tests whether “live” tumor imaging (using a medicine called fluorescein) can be safely performed in people with certain solid cancers.
Jacksonville, FloridaAges 18 years+ - NCT03823534RecruitingPhase 3
Study pain control after preventive femur bone surgery
This Phase 3 study tests a pain medicine plan used after preventive surgery to place a metal rod inside the thigh bone (femur) before a fracture happens. The goal is to find an approach that controls post-surgery pain while being safe for the right patients.
St Louis, MissouriAges 18 years+ - NCT03824145Recruiting
Lifestyle coaching for women with metastatic breast cancer
This study tests a structured lifestyle program (diet and physical activity guidance) for women with metastatic breast cancer. It may help improve well-being and health behaviors, especially if you haven’t been following the recommended nutrition and activity guidelines.
Maywood, IllinoisAges 18 years+ - NCT03825861RecruitingPhase 2
Before-surgery chemotherapy for locally advanced stomach cancer
This Phase 2 study tests chemotherapy given before surgery (called FOLFIRINOX) for people with locally advanced stomach cancer. The goal is to shrink the tumor and improve outcomes after the surgery plan is completed.
São PauloAges 18–75 - NCT03826992RecruitingPhase 1
Study drug Venetoclax plus Vyxeos for hard-to-treat leukemia
This Phase 1 study tests whether a combination of venetoclax and Vyxeos can treat children and young adults with certain relapsed or treatment-resistant acute leukemias. It may help shrink the leukemia or improve blood counts when standard treatments have not worked.
Cincinnati, OhioAges 1–39 - NCT03827317Recruiting
Scan to see HER2 in breast cancer with a new tracer
This study tests a new PET scan tracer to show where HER2-positive breast cancer cells may be in the body. It may help doctors better “map” HER2 activity, including in people with HER2-positive or HER2-negative cancer.
LondonAges 18 years+ - NCT03830320RecruitingPhase 1
PET scan to look for blood clots in the heart or lungs
This Phase 1 study uses a PET scan to detect blood clots (thrombosis) in specific groups of people. It’s testing how well the scan can find clots and how it should be timed with other heart or illness tests.
Boston, MassachusettsAges 18–85 - NCT03828773Recruiting
Azole antifungal prevention for leukemia during low white blood counts
This trial tests whether using a targeted antifungal medicine (aimed at PTX3) can better prevent serious fungal infections in adults with AML or a related bone marrow disease who will have very low neutrophils. It may help lower the risk of dangerous infections during intensive chemotherapy hospital stays.
Ghent, BelgiumAges 18 years+ - NCT03829553RecruitingPhase 3
Radiation to breast lymph nodes versus standard breast cancer care
This Phase 3 trial tests whether a shorter, more focused radiation treatment to the regional lymph nodes works as well as the current standard approach for certain breast cancers. It may help patients by potentially improving treatment efficiency while keeping cancer control effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT03829540RecruitingPhase 1
CD4 CAR T therapy for certain CD4+ blood cancers
This early-phase (Phase 1) study tests a lab-made immune cell treatment (CD4 CAR T) for people with CD4+ leukemia or lymphoma that has come back or did not respond to standard treatment. The goal is to check safety and see how well the treatment works.
Miami, FloridaAges 12 years+ - NCT03829033Recruiting
Photon vs proton radiation for early tonsil cancer
This trial compares two types of radiation—photon therapy and proton therapy—for early-stage tonsil cancer. The goal is to see which approach works well for cure while affecting surrounding tissues differently.
GävleAges 18 years+ - NCT03829254RecruitingPhase 1/Phase 2
NUC-7738 treatment for advanced solid cancers and lymphoma
This early-phase study tests how safe NUC-7738 is and how it works in people with advanced solid tumors and certain lymphomas. Some participants may also receive pembrolizumab for specific cancers, aiming to improve cancer control while carefully monitoring side effects.
CambridgeAges 18 years+ - NCT03830801Recruiting
Testing laser-guided sampling to predict Barrett’s esophagus risk
This study checks whether a special laser-guided method can safely collect tiny tissue samples from the esophagus to help predict how Barrett’s esophagus may turn out. If you have Barrett’s, the results may help doctors better estimate your future risk.
Boston, MassachusettsAges 18 years+ - NCT03830151RecruitingPhase 1
C-13 pyruvate MRI to help diagnose brain gliomas
This early-phase study tests a special MRI scan using C-13 pyruvate to help identify and understand gliomas (a type of brain tumor) in people with brain tumors going to surgery or biopsy. It may help doctors see tumor signals better before or around the time of your procedure.
Houston, TexasAges 19 years+ - NCT03830788Recruiting
Radiation options for early prostate cancer-related erections
This study compares two radiation treatments—seed brachytherapy and stereotactic body radiotherapy—to see which better preserves erections in men with early- to mid-risk prostate cancer. It’s designed to help patients understand how different curative radiation choices can affect sexual function.
AlbiAges 18 years+ - NCT03832127RecruitingPhase 1
PET scan test for multiple myeloma response and treatment effect
This Phase 1 trial tests a special PET scan tracer called 18F-fludarabine to help doctors better assess multiple myeloma at the start of treatment and right after treatment ends. The goal is to see how well this imaging tool can show disease activity so care can be tailored more accurately.
AngersAges 18 years+ - NCT03832062Recruiting
Using leftover cancer tissue to study tumors
This trial studies whether analyzing leftover tissue from cancer surgery can help researchers learn more about tumors. It may help improve future diagnosis or treatment by making use of tissue that would otherwise be discarded.
