PaviaAges Any age - NCT05203328Recruiting
Testing high-flow oxygen during EBUS with monitored sedation
This study looks at whether using high-flow oxygen through the nose during a specific lung procedure (EBUS bronchoscopy) is safe and works well while you receive monitored sedation. If you qualify, it may help improve how breathing is supported during the procedure.
Camden, New JerseyAges 18 years+ - NCT05204186Recruiting
AI Tool to Predict Health Outcomes After Bladder Removal Surgery

Amiens, PicardieAges 18 years+ - NCT05205200RecruitingPhase 2
Immune therapy for HR-positive, HER2-negative metastatic breast cancer
This Phase 2 trial studies an immune-based treatment for women with HR-positive and HER2-negative breast cancer that has spread or returned and can’t be cured with local treatment alone. The goal is to see whether the therapy can shrink tumors and improve disease control with acceptable safety.
ShanghaiAges 18–75 - NCT05207098Recruiting
Brain testing and questionnaires during head and neck radiation
This study checks how people’s thinking and brain functioning change while they are getting radiation therapy for head and neck cancer. It uses simple computer tests and questionnaires to better understand who may be at risk for trouble thinking during treatment.
Basking Ridge, New JerseyAges 18–89 - NCT05206890Recruiting
Registry study of fluzoparib for ovarian, tube, or peritoneal cancer
This is an observational (non-interventional) study that tracks how fluzoparib is used to treat ovarian, fallopian tube, or primary peritoneal cancer in real-world care. It may help doctors better understand how well the treatment works and what side effects patients experience.
Wuhan, HubeiAges 18 years+ - NCT05208047RecruitingPhase 3
CGT9486 plus sunitinib for advanced gastrointestinal stromal tumors
This trial tests whether adding a new drug called CGT9486 to sunitinib (a standard cancer drug) works better than sunitinib alone for gastrointestinal stromal tumors (GISTs) that have grown or spread. You may qualify if your GIST stopped responding to or caused problems with imatinib, an earlier treatment.
Birmingham, AlabamaAges 18 years+ - NCT05209243Recruiting
Treating limited-spread prostate cancer with radiation plus hormone therapy
This trial studies whether adding focused radiation (SBRT) to hormone therapy can control prostate cancer that has spread to only a few places. It aims to help people with early “oligometastatic” prostate cancer by improving disease control while limiting treatment side effects.
MadridAges Any age - NCT05210374RecruitingPhase 1
Disulfiram plus copper and liposomal chemotherapy for hard-to-treat sarcoma
This early-stage study tests a combination of disulfiram (an anti-alcohol medication), copper, and liposomal doxorubicin (a chemotherapy form) in people with sarcoma that has come back or did not respond to treatment. It aims to shrink or control tumors and improve outcomes when standard options have not worked.
Cleveland, OhioAges 18 years+ - NCT05210907RecruitingPhase 1
Hospital-made CD19 CAR-T for relapsed leukemia in children
This Phase 1 study tests a homemade (hospital-manufactured) immune treatment called CD19 CAR-T for children and teens with a type of leukemia that has come back or did not respond. It may help by targeting leukemia cells that carry the CD19 marker.
SeoulAges birth–25 years - NCT05211570RecruitingPhase 1/Phase 2
Study drug AB8939 for AML after prior treatments
This Phase 1/2 study tests AB8939 in people with acute myeloid leukemia (AML) whose disease has come back or did not respond to earlier treatment. It may help researchers find a safe dose and learn whether the treatment can control the leukemia.
Houston, TexasAges 18 years+ - NCT05211557RecruitingPhase 1/Phase 2
CAR-T therapy for recurrent ovarian cancer with B7H3
This Phase 1/2 study tests a personalized immune-cell treatment (fully human B7H3 CAR-T) for ovarian cancer that has come back or did not respond. It aims to see whether CAR-T can attack tumors that carry a target called B7H3.
Xuzhou, JiangsuAges 18–70 - NCT05212454RecruitingPhase 3
Capecitabine added after surgery for high-risk ER-positive breast cancer
This Phase 3 study tests whether adding capecitabine (a chemotherapy pill) after breast cancer surgery can lower the chance the cancer comes back. It targets people with hormone-receptor–positive and HER2-negative breast cancer who are considered “high risk.”
Hanzhou, ZhejiangAges 18–70 - NCT05214612Recruiting
Predictors of outcomes in myasthenia gravis
This study looks at what helps predict outcomes in people with myasthenia gravis (MG). It may help doctors better forecast how MG will progress and which factors matter most for recovery and long-term health.
AsyutAges 16 years+ - NCT05214885Recruiting
Study biomarkers in kidney cancer and healthy people
This study looks at blood or body measures called “biomarkers” to understand how lack of oxygen and body energy changes in clear cell kidney cancer. It compares people with kidney cancer to carefully matched healthy volunteers to see what patterns might help improve understanding or future care.
JinanAges Any age - NCT05214937Recruiting
Help to reduce sitting time in prostate cancer survivors
This study tests an intervention to help prostate cancer survivors sit less and move more. It may help improve daily activity and reduce long periods of inactivity.
Toronto, OntarioAges 18 years+ - NCT05215535Recruiting
Liver MRI before rectal cancer treatment
This trial tests whether doing an MRI scan of the liver before rectal cancer treatment helps doctors plan care better. You may be asked to have MRI before starting treatment and follow the study plan.
GothenburgAges 18 years+ - NCT05216328RecruitingPhase 4
Prevent constipation in people with advanced cancer on opioids
This study tests whether starting a bowel-prevention approach can help stop constipation caused by opioid pain medicines in people with advanced (metastatic) cancer. You may be able to join if you are about to start long-acting or skin opioid pain treatment.
Almere Stad, FlevolandAges 18 years+ - NCT05216432RecruitingPhase 1
RLY-2608 for PIK3CA-mutant advanced solid tumors and breast cancer
This early study (Phase 1) tests RLY-2608, a targeted cancer drug for tumors with a PIK3CA mutation. It studies the drug alone and combined with hormone therapy (and sometimes CDK4/6 or CDK4 medicines) to see safety, dose, and whether it can shrink tumors.
Tucson, ArizonaAges 18 years+ - NCT05216900Recruiting
Breast reconstruction with radiation given before surgery
This study looks at how breast reconstruction works when radiation is planned around the time of surgery, including in some people before surgery depending on lymph node results. It may help improve safety and outcomes for people needing mastectomy and chest/radiation therapy.
Bilthoven, UtrechtAges 18–75 - NCT05217940Recruiting
Screening women with prior HPV for anal abnormalities
This study looks for early anal cell changes in women who have had high-grade HPV-related problems in the cervix, vagina, or vulva. It may help find concerning changes sooner, using a structured screening exam.
New York, New YorkAges 35 years+ - NCT05217966Recruiting
Radiation before possible breast surgery for early ER-positive cancer
This study gives radiation to the breast before surgery to see if some people can safely delay or even skip surgery. It targets women with a small, node-negative, ER-positive breast cancer with low genetic risk.
Montreal, QuebecAges 50 years+ - NCT05218044Recruiting
Cryoablation for small DCIS instead of breast surgery
This trial studies whether cryoablation (freezing abnormal breast tissue) can treat DCIS, a non-invasive early breast cancer, without surgical lumpectomy. It aims to see if a less invasive approach could help people with small, limited-area DCIS while avoiding some effects of surgery.
