Sleep apnea study in people with MGUS or multiple myeloma
This study looks at sleep apnea (breathing pauses during sleep) in people who have MGUS or multiple myeloma. You may be asked to participate because you already need a bone marrow biopsy as part of your usual care.
Iowa City, IowaAges 18–99 - NCT04115241Recruiting
Study of activity levels during bone marrow transplant
This study looks at how active people are during a bone marrow transplant. The goal is to better understand activity patterns during transplant care and recovery.
Iowa City, IowaAges 18–99 - NCT04115254Recruiting
MRI-guided focused radiation for certain tumors
This study tests a type of high-precision radiation guided by MRI pictures to treat certain cancers. It may help doctors deliver radiation more accurately while avoiding nearby healthy tissue, but you must be able to safely complete an MRI scan and meet tumor-size and health requirements.
Boston, MassachusettsAges 18 years+ - NCT04116502RecruitingPhase 3
Ruxolitinib versus standard treatments for high-risk polycythemia vera
This Phase 3 study compares ruxolitinib against hydroxycarbamide or interferon as the first treatment for people with high-risk polycythemia vera. It aims to see which option works better to reduce disease-related problems and complications.
AberdeenAges 18 years+ - NCT04118660Recruiting
Thoracic specimen registry for adults with chest conditions
This study is a “specimen registry,” meaning it collects and stores samples from adults with chest (thoracic) diseases. It may help researchers better understand lung and chest conditions and improve future testing or treatments.
Rochester, MinnesotaAges 18 years+ - NCT04119713Recruiting
Study how the immune system changes after cancer immunotherapy
This study looks at what happens to your immune system after you start a type of cancer treatment called a checkpoint inhibitor. The goal is to better understand side effects related to “autoimmunity” (when the immune system starts attacking the body) and improve care.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Duarte, CaliforniaAges 18–75 - NCT04120935Recruiting
Observational study for adults with possible or confirmed bowel cancer
This study mainly watches and records health information from adults with colorectal cancer (or a strong suspicion of it). It collects past tumor tissue and other clinical details to better understand the disease and care.
Biella, BiellaAges 18 years+ - NCT04122313Recruiting
Radiation after surgery for Dupuytren’s hand contracture
This trial looks at using radiation after contracture-release surgery for people with Dupuytren’s disease. It may help prevent the hand tightening from coming back and improve hand function.
Minneapolis, MinnesotaAges 18 years+ - NCT04122872Recruiting
German sarcoma registry for adults with rare tumor types
This study is a German “registry,” meaning it collects information about people with specific bone or soft tissue tumors (including some borderline or hard-to-classify cases). It helps doctors and researchers learn more about these rare conditions to improve future care.
Tübingen, Baden-WurttembergAges 18 years+ - NCT04126876RecruitingPhase 2
IMO-2125 skin injection for thick, early-stage melanoma
This trial tests whether an injection given into the skin (IMO-2125) can improve outcomes for people with thicker primary melanoma that has not spread to lymph nodes or other organs. Participants also have planned surgery to remove the tumor and check a sentinel lymph node.
AmsterdamAges 18 years+ - NCT04127552Recruiting
Adrenal mass screening and hormone effects on health
This study looks at how an accidentally found adrenal growth may affect heart and metabolic health, especially if it causes extra cortisol production. It may help explain which people are at higher risk and what monitoring or treatment could be useful.
Rome, ItalyAges 18–80 - NCT04128072RecruitingPhase 2
Mogamulizumab plus skin radiation for cutaneous T-cell lymphoma
This trial studies mogamulizumab (an antibody medicine) plus total skin electron beam therapy (whole-skin radiation) to treat cutaneous T-cell lymphoma. It may help by improving skin symptoms and controlling the lymphoma after prior treatments.
CopenhagenAges 18 years+ - NCT04132895Recruiting
Study to improve outcomes in osteosarcoma care through collaboration
This trial focuses on improving how osteosarcoma care is coordinated and delivered, using collaboration between clinicians. It may help by helping teams make more consistent treatment decisions for people newly diagnosed.
London, Greater LondonAges Any age - NCT04130971Recruiting
Testing tumor tissue to understand and predict colorectal cancer response
This study looks at tissue samples from people with colorectal cancer to better understand tumor features and how they may respond to treatment. If you have colorectal cancer, the trial may help researchers match future treatments more effectively.
GothenburgAges 18 years+ - NCT04133285Recruiting
Registry for people with multiple bone growths
This study is a registry that collects information about people with multiple osteochondromas (extra bone/cartilage growths). It may help researchers better understand the condition and improve future care, even if no treatment is given.
Bologna, Emilia-RomagnaAges Any age - NCT04134780Recruiting
Ultrasound tests to spot early breast cancer treatment response
This study uses special ultrasound imaging (and may use MRI results) to look for early signs of how locally advanced breast cancer responds to chemotherapy, with or without radiation. If the imaging changes early, it could help doctors adjust treatment sooner.
Houston, TexasAges 18 years+ - NCT04136132Recruiting
Pancreatic cancer patient database for research
This study collects medical and lab information from adults with pancreatic cancer to help researchers understand care and outcomes. You may be asked for follow-up visits and basic data, and it may be used to improve future treatments.
Montpellier, OccAges 18 years+ - NCT04134559RecruitingPhase 2
Pembrolizumab for kids with liver cancer that came back
This trial studies pembrolizumab (an immune therapy) in children and young people with hepatocellular carcinoma (HCC) that has returned or did not respond to earlier treatment. The goal is to see whether it can shrink tumors and help control the cancer.
San Francisco, CaliforniaAges birth–30 years - NCT04135664RecruitingPhase 3
Compare surgery vs chemoradiation for early throat cancer
This study compares two ways to treat a type of esophagus cancer: surgical removal (esophagectomy) versus chemoradiation (chemo plus radiation). It is for people with early-stage findings where scans suggest no lymph node spread.
Nanchang, JiangxiAges 18–75 - NCT04136535RecruitingPhase 2
Treating resistant lung cancer with chemo plus or minus an added drug
This Phase 2 study tests whether adding an extra targeted medicine (anlotinib) to standard chemotherapy (pemetrexed and carboplatin) can better control osimertinib-resistant lung cancer with an EGFR mutation. It’s for people whose lung cancer has already progressed after osimertinib, and it aims to shrink tumors and slow the disease.
Shenzhen, shenzhenAges 18–75 - NCT04135807RecruitingEarly Phase 1
Implantable device test for operable brain tumor patients
This early-phase trial tests a tiny implanted device placed during brain tumor surgery. It delivers very small doses of medicine directly to the tumor area for a short time, aiming to see if this approach is safe and workable in patients with certain gliomas.
Boston, MassachusettsAges 18 years+ - NCT04136782RecruitingPhase 4
Tests two chemo drug combinations for triple-negative breast cancer
This Phase 4 trial compares two chemotherapy combinations to treat stage II–III triple-negative breast cancer. It looks for which regimen works better and is tolerated in people with measurable tumors and good overall health.
Harbin, HeilongjiangAges 18–70 - NCT04136886RecruitingPhase 3
Chemo trial for return of advanced nasopharyngeal cancer
This Phase 3 study tests a chemotherapy plan for people whose nasopharyngeal cancer has come back locally (T3/T4). It aims to see if treatment given after return of cancer can help control the disease without spreading to distant organs.
