Cleveland, OhioAges 18–65 - NCT04360330Recruiting
MRI study in early breast cancer with specific lab markers
This study tests selected treatment decisions for women with early-stage breast cancer that has certain lab test results. It may help researchers better match care using MRI and tumor marker information.
Miami, FloridaAges 50 years+ - NCT04222413RecruitingPhase 1
Study of metarrestin for advanced solid tumors
This study tests an experimental drug called metarrestin for people with solid tumors that have spread or come back after standard treatment. It may help by targeting a protein involved in cancer cell growth.
Fairway, KansasAges 12–120 - NCT04203849Enrolling by invitation
Study of breast cancer patients getting radiotherapy
This study follows breast cancer patients who are scheduled to receive radiotherapy at a National Cancer Center in Korea. By collecting information during and after treatment, researchers hope to better understand how patients do over time.
Goyang-si, Gyeonggi-doAges 20 years+ - NCT04167969RecruitingPhase 1
Nanoparticles to help guide prostate cancer surgery
This Phase 1 study tests nanoparticles (tiny particles) that are meant to help surgeons better find and remove prostate cancer tissue during surgery. You may be offered standard prostate surgery plus imaging with a study tracer to guide the operation.
New York, New YorkAges 18 years+ - NCT04199741RecruitingPhase 1/Phase 2
PET/CT scan test for small cell lung cancer marker DLL3
This trial tests a special PET/CT imaging scan that may help doctors find where small cell lung cancer (and some related tumors) are in the body using a DLL3 target. It’s a Phase 1/2 study, mainly to see how well the scan detects tumors and guides care.
New York, New YorkAges 18 years+ - NCT04178174RecruitingPhase 3
Boost radiation for HPV throat cancer with shorter treatment
This trial studies whether adding a precise “extra boost” to radiation can work as well as (or better than) standard radiation for HPV-related oropharynx cancer, while keeping the overall treatment shorter. It may help improve tumor control while aiming for manageable side effects.
London, OntarioAges 18 years+ - NCT04253964RecruitingPhase 2
Chemotherapy plus immunotherapy for advanced lung cancer
This study tests a combination of chemotherapy and immunotherapy in people with advanced non-small cell lung cancer that has spread or cannot be removed with surgery. The goal is to see how well this treatment works in patients with different levels of daily activity.
Charlotte, North CarolinaAges 18 years+ - NCT04073706RecruitingPhase 3
Sentinel node biopsy for early womb cancer
This trial tests whether a less invasive way to check if cancer has spread to lymph nodes (sentinel node biopsy) works as well as the standard method. It is for people with early-stage endometrial cancer having surgery.
