Study on thoughts and body image during breast reconstruction
This study looks at how people’s expectations and body image feelings may affect experiences after breast reconstruction after mastectomy. It may help doctors understand what kinds of support or counseling could make recovery feel better.
GothenburgAges 18 years+ - NCT04714957Recruiting
Personalized study for cancer spread in the belly lining
This trial studies people whose cancer has spread to the lining of the abdomen (the “belly lining”), including cancers from the digestive tract or ovaries. You may be asked to join because the study aims to learn how to better match care to different patterns of this belly lining cancer spread.
LyonAges 18 years+ - NCT04715178Recruiting
Childhood cancer sample and data registry
This study collects stored samples (like blood or tissue) and health information from people affected by cancer at a young age, including some survivors. The goal is to build a library of specimens and data that researchers can use to better understand childhood and young adult cancers.
Little Rock, ArkansasAges Any age - NCT04716257Recruiting
Study of treatment outcomes in ovarian-spread colorectal cancer
This study follows women with colorectal cancer that has spread to the ovaries to see how care works in real life. It may help doctors understand which patients benefit most and how treatment choices affect outcomes.
Guangzhou, GuangdongAges 18 years+ - NCT04715581Recruiting
Pre-surgery rehab program for frail older adults having stomach surgery
This trial studies a “prehabilitation” program—exercise and coaching before surgery—to help frail older adults recover better after major digestive cancer surgery. It may help you strengthen your body and function before the operation, which can improve outcomes after surgery.
Beijing, Beijing MunicipalityAges 65–89 - NCT04716686RecruitingPhase 2
Niraparib alone to help prevent cancer coming back
This Phase 2 study tests niraparib by itself to keep endometrial serous cancer from returning or to control it after chemotherapy helps. It may help some people by targeting tumor DNA repair weaknesses, especially in cancers with certain gene changes.
Jinan, ShandongAges 18 years+ - NCT04716452RecruitingPhase 1
Testing a ceramide liposome drug for relapsed or resistant AML
This Phase 1 trial tests a new targeted treatment (C6 ceramide in a tiny fat-like capsule) for adults with acute myeloid leukemia (AML) that has come back or did not respond to treatment. The goal is to see how the drug works and how safe it is in this setting.
Charlottesville, VirginiaAges 18 years+ - NCT04719156RecruitingPhase 2
Fluorescent dye to check tumor margins during surgery
This Phase 2 study tests whether using a fluorescent dye during tumor surgery can help the surgical team better see where the tumor ends. It may help aim for complete removal and lower the chance of the tumor coming back.
Pittsburgh, PennsylvaniaAges 18–100 - NCT04721041Recruiting
Fecal microbiota transplant for gut side effects after cancer treatment
This trial tests a treatment called “washed microbiota transplant,” which transfers healthy gut bacteria to help relieve intestinal problems that started after cancer therapy. You might benefit if you’re an adult with certain ongoing stomach or bowel symptoms after standard cancer treatment, and your body is stable enough for the procedure.
Nanjing, JiangsuAges 18 years+ - NCT04721717Recruiting
Workshop for healing writing after paralysis
This trial tests whether a structured writing workshop can help people living with paralysis and their ALS caregivers. It focuses on communication through words (spoken or written) to support well-being.
Birmingham, AlabamaAges 18 years+ - NCT04722341Recruiting
Time-limited eating for people with certain breast or rectal cancers
This study tests whether eating only within a shorter daily time window can improve cancer outcomes in people with specific breast or rectal cancers. It also looks at how this affects the body (such as metabolism) and who is most likely to benefit.
Birmingham, AlabamaAges 18 years+ - NCT04722692RecruitingPhase 3
Delayed sentinel lymph node biopsy for ductal cancer in situ
This trial tests whether doing a sentinel lymph node biopsy later (after breast surgery) is a safe, accurate way to check if cancer has spread. It uses a special tracking shot that helps find the lymph nodes.
Houston, TexasAges 18 years+ - NCT04723316Recruiting
Tumor testing to guide targeted cancer treatment
This trial looks at your tumor (and blood) to find helpful targets so doctors can match you to an experimental targeted therapy, if one fits. It may help by using detailed “tumor profiling” to choose treatments more precisely for your cancer.
BelfastAges 16 years+ - NCT04722978RecruitingPhase 3
Chemo plus moxifloxacin for metastatic triple-negative breast cancer
This trial tests whether adding moxifloxacin (an antibiotic) to standard chemotherapy helps people with metastatic triple-negative breast cancer live longer or respond better. You may qualify if your cancer has the right lab markers and you haven’t had treatment for metastatic disease yet.
Guangzhou, GuangdongAges 18–70 - NCT04723095Recruiting
Cervical neuroendocrine cancer registry for past and present patients
This study builds a registry (a secure database) of people who have had cervical neuroendocrine cancer, including small cell or large cell types. It helps researchers learn more about these cancers and may improve future care and research planning.
Houston, TexasAges Any age - NCT04723862RecruitingEarly Phase 1
Spironolactone to test sleep hormone patterns in teen girls
This early-phase study tests whether spironolactone can “normalize” a key hormone timing pattern during sleep and wake cycles in mid-to-late pubertal girls who have high male-hormone levels. The goal is to learn how this medicine may affect hormone rhythms related to conditions like PCOS.
Charlottesville, VirginiaAges 10–17 - NCT04724018RecruitingPhase 1/Phase 2
Enfortumab and sacituzumab for metastatic bladder cancer
This Phase 1/2 trial tests whether combining sacituzumab govitecan with enfortumab vedotin (and in one group, pembrolizumab) can shrink or control metastatic urothelial (bladder/urinary tract) cancer. It’s mainly for people whose cancer has grown despite prior treatment.
Boston, MassachusettsAges 18 years+ - NCT04723810RecruitingPhase 1/Phase 2
Test a glowing scan to help surgeons find tumor tissue
This early-stage study tests an intraoperative imaging approach called “TumorGlow” to help surgeons better identify tumor tissue during surgery. It may help improve the completeness of tumor removal and reduce the chance of recurrence in certain patients.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04725903Recruiting
Proton beam radiation for high-risk prostate cancer
This trial tests proton radiation therapy for people with high-risk prostate cancer. It may help by delivering radiation in a more targeted way, with the goal of controlling the cancer while reducing exposure to nearby healthy tissue.
Atlanta, GeorgiaAges 18 years+ - NCT04726228Recruiting
Using machine learning to improve pain assessment in advanced cancer
This trial looks at how a computer “learns” to better understand and assess cancer pain at home. It may help people with advanced cancer get more accurate pain evaluation while they are receiving pain treatment.
Naples, CampaniaAges 18 years+ - NCT04729114RecruitingPhase 1
Safety and dose test of PRL-02 shot for advanced prostate cancer
This Phase 1 study tests how safe PRL-02 depot (an injection) is and finds the best dose for men with advanced prostate cancer. It may help determine a new treatment option for cancers that have spread or are getting worse despite standard care.
Tucson, ArizonaAges 18 years+ - NCT04728724RecruitingPhase 2
Check immune treatment before surgery for stage III lung cancer
This Phase 2 trial tests an “immunotherapy” medicine given before surgery for stage III non-small cell lung cancer. The goal is to shrink the cancer and make curative surgery more successful while monitoring safety and response.
ShanghaiAges 18–75 - NCT04729543RecruitingPhase 1/Phase 2
TCR cell therapy for melanoma and head and neck cancer
This early-phase study tests a lab-made T-cell treatment that targets a specific tumor marker (MC2) in melanoma and head and neck cancers. It aims to see if the treatment can safely shrink tumors and control cancer after standard options have run out.
RotterdamAges 18 years+ - NCT04731558RecruitingPhase 4
Blood clot prevention before versus after liver surgery
This study compares two approaches to preventing blood clots around the time of liver surgery. If you’re having planned liver surgery, it may help doctors choose the safest timing and method for clot prevention.
