Quality-of-life study after standard treatment for anal cancer
This observational study follows people with anal cancer to understand how their quality of life changes after they receive standard chemoradiation therapy. It may help doctors better support patients with symptoms, recovery, and daily functioning over time.
Munich, BavariaAges 18 years+ - NCT03793517RecruitingPhase 2/Phase 3
Decitabine plus chemotherapy before stem cell transplant for high-risk leukemia
This trial studies whether adding decitabine plus chemotherapy before a stem cell transplant can better control “minimal residual disease” (very small amounts of leukemia left behind) in certain high-risk acute leukemia types. It may help reduce the chance of the leukemia coming back after transplant.
Beijing, Beijing MunicipalityAges 18–55 - NCT03796559Recruiting
Magnetic marker helps find breast cancer lymph nodes
This study uses a tiny magnetic marker (called Magseed) placed in a breast cancer–affected underarm lymph node, then tracks whether surgeons can find and remove the correct nodes after chemotherapy. It may help reduce the chance of missing cancer in the underarm while aiming for more accurate surgery.
Houston, TexasAges 18 years+ - NCT03797690Recruiting
Needle procedure for Dupuytren’s hand contracture
This trial looks at whether a minimally invasive needle procedure can improve hand stiffness caused by Dupuytren’s disease. It may help reduce finger bending that affects how you use your hand.
ParisAges 18 years+ - NCT03802851Recruiting
Laser procedure before radiation for prostate cancer symptoms
This trial looks at whether doing a prostate “laser procedure” (called HoLEP) before starting radiation and hormone therapy can improve severe urinary symptoms and reduce urine retention problems. It is for people with prostate cancer who are planning radiation plus hormone treatment and who have significant bladder/urinary trouble.
Kansas City, KansasAges 18 years+ - NCT03800693RecruitingPhase 2
Shorter vs longer oxaliplatin infusions for gut cancer
This Phase 2 study compares giving oxaliplatin by IV for 2 hours versus 6 hours, along with the standard FOLFOX6 chemotherapy. It aims to see if the shorter infusion works as well and is manageable for people with gastrointestinal cancers.
Atlanta, GeorgiaAges 18 years+ - NCT03802773Recruiting
Cord blood transplant with strong chemo to prevent relapse
This trial tests a cord blood transplant using strong (myeloablative) chemotherapy to prepare your body, plus post-transplant treatment to reduce graft-versus-host disease (GVHD). It may help certain blood cancers when other transplant options are limited.
Roma, RMAges 18–75 - NCT03803787RecruitingPhase 2
Inhaled steroid to prevent lung inflammation during cancer treatment
This trial tests whether breathing in steroid medicine before and during radiation can lower how often and how badly “radiation lung inflammation” (radiation pneumonitis) happens in people with lung cancer. If you qualify, it may help protect your lungs while you receive radiation with chemotherapy or targeted therapy.
Mexico CityAges 18–75 - NCT03803735Recruiting
Hospital cancer registry for children in French-speaking Africa
This trial is a hospital-based registry that collects information about children and teens with cancer as they receive treatment. It may help researchers better understand cancer care in this region and improve future planning and treatment.
OuagadougouAges 1 day–18 years - NCT03807128Recruiting
Study for multiple myeloma resistance and relapse changes
This study looks at how multiple myeloma (a bone marrow cancer) changes over time, especially why it becomes resistant to treatment or comes back. It may help researchers learn what drives relapse and could lead to better future treatments.
La Roche-sur-YonAges 18 years+ - NCT03804320Recruiting
Watching small kidney tumors over time instead of treating
This study follows people with small, solid kidney tumors using active surveillance (regular monitoring) rather than immediate surgery or treatment. It may help you understand whether careful watching is a safe option for certain early kidney tumors.
MilanAges 50 years+ - NCT03804944RecruitingPhase 2
Vaccine trial for hormone-positive breast cancer
This Phase 2 study tests an individualized vaccine made from your tumor information to help your immune system fight hormone-positive breast cancer. You may be able to participate if you meet specific hormone-receptor, health, and treatment-timing requirements.
Los Angeles, CaliforniaAges 18–90 - NCT03805022RecruitingPhase 3
Extra chemotherapy around surgery for high-risk soft-tissue sarcoma
This trial tests whether giving stronger chemotherapy before and/or after surgery helps people with high-risk, resectable soft-tissue sarcoma. It aims to lower the chance the cancer comes back by improving treatment around the time of the operation.
BordeauxAges 18 years+ - NCT03805919Recruiting
Study for men with high inherited risk of prostate cancer
This study is for men who have a known inherited gene change that raises their prostate cancer risk. It aims to help prevent or detect prostate cancer earlier, and you may be asked to undergo MRI and other study steps.
Bethesda, MarylandAges 30–75 - NCT03807687Recruiting
Registry for people with pancreatic diseases
This is a registry that collects information from people who have a pancreatic disease. It may help doctors better understand different pancreatic conditions and improve future care.
VeronaAges 18 years+ - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.
San Carlos, CaliforniaAges 18 years+ - NCT03809585Recruiting
Study of iris tumors and healthy eyes
This observational study looks at eyes with iris tumors and compares them to eyes without iris problems. The goal is to better understand how iris circulation and related eye measurements differ, which may help future care.
Portland, OregonAges 18 years+ - NCT03810651RecruitingEarly Phase 1
Radiation planning for kidney tumors in children and teens
This early study tests a type of radiation delivery (“pencil beam scanning”) for certain kidney cancers in children and teens. It may help doctors better target the tumor while reducing radiation to nearby healthy tissue.
Philadelphia, PennsylvaniaAges birth–30 years - NCT03812874RecruitingPhase 1/Phase 2
Drug after chemo-embolization for liver cancer that can’t be removed
This Phase 1/2 study tests PTX-9908 (a study drug) to see if it’s safe and effective when given after TACE, a liver-directed treatment. It may help people with liver cancer that can’t be surgically removed and who have recovered enough from their recent TACE.
New Taipei City, TaiwanAges 20 years+ - NCT03815890RecruitingPhase 2
Pre-surgery nivolumab for certain types of breast cancer
This trial tests whether giving nivolumab before surgery (neoadjuvant treatment) can improve outcomes for people with certain resectable breast cancers. It focuses on tumor types linked to immune activity (like triple-negative and specific lab markers).
AmsterdamAges 18 years+ - NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor
This trial studies giving cyclophosphamide after a stem cell transplant when there is no matched sibling donor, but a well-matched unrelated donor is available. It aims to improve outcomes for people with blood cancers undergoing this transplant.
São Paulo, São PauloAges 1–75 - NCT03816345RecruitingPhase 1
Nivolumab for advanced cancer with autoimmune conditions
This Phase 1 study tests nivolumab, an immunotherapy “anti-cancer accelerator,” in people with advanced cancer who also have an autoimmune disorder. It aims to see if nivolumab can be given safely and whether it may help shrink or control cancer.
Birmingham, AlabamaAges 18 years+ - NCT03819101RecruitingPhase 3
Aspirin plus atorvastatin for advanced, treatment-resistant prostate cancer
This trial studies whether daily aspirin and atorvastatin can slow advanced prostate cancer that has continued to grow despite hormone therapy. It may help by reducing cancer growth and inflammation, but you would need to meet several specific safety and medication rules.
OlomoucAges 18 years+ - NCT03818412Recruiting
Liquid biopsy for soft tissue sarcoma
This study checks if a blood test can detect DNA from soft tissue sarcomas. The goal is to see if circulating tumor DNA can help doctors monitor the disease and plan treatment.
