Genetic testing study for kidney cancer
This study looks at genetic features of kidney cancer by testing tumor samples. The goal is to find biomarkers—specific signs—that may help predict what kind of kidney cancer it is.
RoskildeAges Any age - NCT03417115Recruiting
Breast cancer registry study of treatment and outcomes
This is a registry study that collects real-world information about breast cancer care at the start of treatment. It may help researchers better understand which treatments work best for different groups of people.
Many LocationsAges 18 years+ - NCT03417622RecruitingPhase 3
Wide vs narrow breast surgery margins after lumpectomy
This study compares two ways of cutting the edge (margin) of tissue during lumpectomy after breast cancer treatment. It may help reduce the chance of the cancer coming back locally by testing whether a wider margin is better than a narrow one.
Al Mansurah, DKAges 18 years+ - NCT03416959Recruiting
Register study for surgery patients with long-bone bone metastases
This trial collects and follows information about people who had surgery to treat cancer that spread to their long bones (like the femur or humerus) to prevent or fix a broken bone. It may help doctors better understand outcomes after these surgeries and improve future care.
Bologna, BolognaAges Any age - NCT03418038RecruitingPhase 2
Vitamin C with chemotherapy for certain relapsed blood cancers
This Phase 2 trial tests whether intravenous vitamin C (ascorbic acid) added to chemotherapy can improve outcomes for people with certain relapsed or treatment-resistant lymphomas or chronic myelomonocytic leukemia (CMML). It may help by boosting chemotherapy’s effectiveness and/or changing how the cancer responds.
Mankato, MinnesotaAges 18 years+ - NCT03418961RecruitingPhase 3
Study of heart-risk management for metastatic HER2 breast cancer
This trial follows people with metastatic HER2-positive breast cancer who are at higher risk for heart damage while on HER2-targeted therapy. Some participants are randomly assigned to different monitoring/heart-protection approaches to see what best helps keep the heart safe.
Anchorage, AlaskaAges 18 years+ - NCT03422302Recruiting
CPAP or breath-holding to reduce lung tumor motion
This study looks at whether using a CPAP breathing device or deep breath-holding can keep lung tumors from moving during targeted radiation. The goal is to improve safety and accuracy of stereotactic body radiation for lung cancer.
Houston, TexasAges 18 years+ - NCT03424850RecruitingPhase 1/Phase 2
Tested different radiation doses for early prostate cancer
This trial studies how safe and effective different high-dose radiation levels are for prostate cancer placed directly in the prostate (HDR brachytherapy). It may help by finding a dose that controls the cancer while keeping side effects acceptable.
St Louis, MissouriAges 18 years+ - NCT03425526RecruitingPhase 1
Donor T-cell treatment for adenovirus illness in immune-weakened people
This early-phase study tests donor immune cells (T cells) to treat people who have adenovirus infection or adenovirus-related disease but have a weakened immune system. It may help your body fight the virus, especially in cases where other treatments may not be enough.
Houston, TexasAges Any age - NCT03435042Recruiting
Hypnosis group program to help children with cancer and parents
This trial tests a hypnosis-based group program to improve quality of life for children with cancer and their parents. You may join if your family speaks French and the child is aged 8–18 and has cancer (or has a sibling with cancer).
LiègeAges 8 years+ - NCT03436069Recruiting
Finding new markers to predict breast cancer outlook
This study looks for new lab “markers” that may help predict how breast cancer is likely to behave over time. Your tumor or health information may be used to find factors that can guide doctors’ predictions.
GrenobleAges 18 years+ - NCT03438474Recruiting
Lymph node surgery study for certain early endometrial cancers
This trial studies whether adding lymph node removal (lymphadenectomy) during surgery helps people with certain early-stage endometrial cancer. It focuses on patients who do not have visibly enlarged lymph nodes and who can safely have the operation.
AalenAges 18–75 - NCT03439371Recruiting
Micro-transplant treatment for older adults with AML in remission
This trial studies a gentler (“micro-”) transplant approach for people ages 60–74 with acute myeloid leukemia (AML) who are in remission and cannot safely have the usual stronger transplant conditioning. It may help reduce transplant risks while keeping the leukemia under control.
Clermont-FerrandAges 60–75 - NCT03449238RecruitingPhase 1/Phase 2
Pembrolizumab with focused brain radiation for breast cancer brain spread
This trial studies whether pembrolizumab (an immune therapy medicine) plus stereotactic radiosurgery (focused radiation) can better control brain metastases from breast cancer. It may help shrink or slow growth of multiple brain spots with minimal treatment to surrounding tissue.
New York, New YorkAges 19–90 - NCT03445585Recruiting
Biobank study for primary sclerosing and primary biliary cholangitis
This study collects and stores samples from people with PSC (primary sclerosing cholangitis), PBC (primary biliary cholangitis), and some related liver conditions. Researchers use these samples to better understand these diseases and support future research.
Rochester, MinnesotaAges 18–85 - NCT03442465Recruiting
Study of healing and function after bone reconstruction surgery
This study looks at how well people heal and how well they can move and use the repaired bone after reconstructive surgery for bone tumors. It may help doctors understand what recovery looks like and what could improve function over time.
Basking Ridge, New JerseyAges 4 years+ - NCT03448926Recruiting
DCIS test registry to guide radiation and drug decisions
This study collects information from people with breast ductal carcinoma in situ (DCIS) to see how a specific lab test (DCISionRT) may help predict who benefits from radiation and/or certain medications. Your results and clinical details are gathered during routine care, not necessarily to change treatment right away.
Scottsdale, ArizonaAges 30–85 - NCT03449264Recruiting
Database study for people with certain new cancers
This study builds a clinical and biological database for people newly diagnosed with certain cancers. It may help doctors better understand cancer patterns and improve future care, and it involves agreeing to extra blood samples.
MontpellierAges 18 years+ - NCT03451383Recruiting
Study brain changes in older breast cancer patients
This study follows older women with newly diagnosed breast cancer to see who might develop thinking or memory problems over time. It may help researchers understand early brain risk and how treatment and other factors relate to cognitive decline.
Washington D.C., District of ColumbiaAges 60–105 - NCT03450512Recruiting
Study of bowel inflammation in adults with AML on intensive treatment
This study looks at how often a serious bowel problem (neutropenic enterocolitis) happens in adults with acute myeloid leukemia (AML) during intensive chemotherapy that lowers infection-fighting cells. The results may help doctors monitor and prevent complications during treatment.
AmiensAges 18 years+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Birmingham, AlabamaAges Any age - NCT03458221RecruitingPhase 2/Phase 3
Biology-guided test on recurrent ovarian cancer activity
This trial studies whether a targeted treatment, chosen based on tumor biology, can help people with recurrent ovarian cancer. You may be asked to give a tumor biopsy so researchers can analyze specific “signal” activity in your cancer.
Nijmegen, GelderlandAges 18 years+ - NCT03457415Recruiting
Provide sputum sample for lung cancer testing
This study collects sputum (mucus from deep in the lungs) to help test or label lung cancer-related results. You may be placed in a healthy, high-risk, or cancer group depending on your smoking history and whether you already have a lung cancer diagnosis.
Summit, New JerseyAges 21 years+ - NCT03458520Recruiting
Kid PET/MR scan registry for solid tumor imaging
This study is a registry that collects images from children (and some adults) with suspected or confirmed solid tumors to help researchers learn how best to use PET/MR scans. It may help future patients by improving imaging and diagnosis planning.
