Study tracking long-term health after childhood cancer
This study follows people in Switzerland who finished treatment for childhood or teen cancer to learn about their long-term health. It may help doctors better understand late effects and follow-up needs after cancer treatment.
BaselAges Any age - NCT04732065RecruitingPhase 1
ONC206 for certain brain tumors in children and young adults
This Phase 1 study tests ONC206, a new targeted medicine, for diffuse midline gliomas (DMG) with a specific gene change (H3K27 altered) and for some other recurrent brain/spinal cord cancers. It is designed to find the right dose and see whether it can control or shrink tumors after initial treatment or when the cancer returns.
San Francisco, CaliforniaAges 2–21 - NCT04732156Recruiting
Test AI and MRI scores to spot prostate cancer
This study compares how well a doctor’s MRI reading (the PI-RADS score) and a computer AI tool detect prostate cancer. It may help improve how men get targeted biopsies and avoid missing important cancers.
BordeauxAges 18–80 - NCT04733430Recruiting
Study lung cancer care in real life
This study follows adults with confirmed lung cancer as they are diagnosed and treated in routine clinical practice. It aims to better understand how lung cancer is diagnosed and managed day-to-day, which may help improve future care.
ViennaAges 18–125 - NCT04733820RecruitingPhase 3
Extra chemo after surgery for advanced cervical cancer
This Phase 3 trial tests whether adding chemotherapy after surgery helps people with locally advanced cervical cancer, especially when prior treatment didn’t fully match standard guidelines. It looks at whether this “adjuvant” chemotherapy improves outcomes after neoadjuvant chemotherapy and an extensive hysterectomy.
Wuhan, HubeiAges 18–70 - NCT04734730RecruitingPhase 2
Talazoparib plus hormone therapy for metastatic prostate cancer
This trial tests whether talazoparib added to standard hormone therapy (ADT), along with abiraterone, can better control metastatic prostate cancer that hasn’t progressed despite starting hormone treatment. It may help people live longer and delay cancer worsening.
Duarte, CaliforniaAges 18 years+ - NCT04734821Recruiting
Fluorescent imaging during stomach or esophagus surgery
This study tests whether a special fluorescent camera during surgery can help surgeons better operate on resectable (removable) stomach or esophagus cancer. It may help improve how surgery is guided, with the goal of safer and more accurate tumor removal.
StrasbourgAges 18 years+ - NCT04735198Recruiting
Preventive gallbladder removal for midgut neuroendocrine tumors
This trial looks at whether removing the gallbladder before it causes problems can be helpful for people with midgut neuroendocrine tumors who are already planning primary tumor surgery. It may reduce future gallbladder-related complications around the time of cancer treatment.
Badalona, BarcelonaAges 18 years+ - NCT04740424RecruitingPhase 1
First study of a new drug for advanced solid cancers
This Phase 1 trial tests a brand-new treatment (given at increasing doses) for people with advanced, unresectable, or metastatic solid tumors. It mainly looks at safety and how the drug behaves in the body, and it may help if standard treatments didn’t work or aren’t suitable.
Waratah, New South WalesAges 18 years+ - NCT04739072Recruiting
Check colorectal cancer blood tests after curative treatment
This study measures “minimal residual disease,” meaning tiny amounts of cancer that may remain after surgery, using blood samples. It may help doctors better detect who is at higher risk of cancer coming back and guide follow-up care.
Gilbert, ArizonaAges 18 years+ - NCT04740346Recruiting
Study survival and quality of life by follow-up time after stomach surgery
This study looks at how long people with stage II or III stomach (gastric) cancer tend to live and how their day-to-day well-being changes over different follow-up times after surgery. It may help doctors understand the best follow-up schedule to support recovery.
Goyang-si, Gyeonggi-doAges 19 years+ - NCT04741737Recruiting
Repeat lymph node biopsy for recurrent breast cancer
This study tests whether repeating a specific lymph node biopsy (sentinel lymph node biopsy) is safe and useful in people whose breast cancer has come back in the same breast. It may help doctors better understand whether lymph nodes are involved and guide next steps after surgery.
SeoulAges 19 years+ - NCT04740697Recruiting
Complementary therapies to help people stay on tamoxifen
This study looks at whether adding alternative or complementary supports can improve how well people stick with tamoxifen treatment for early hormone-related breast cancer. If it helps adherence, it may help people benefit more reliably from their prescribed therapy.
ToulouseAges 1.5 years+ - NCT04741997RecruitingEarly Phase 1
Adjuvant melanoma treatment guided by response to targeted drugs
This early-phase study looks at whether people with melanoma can get the “right” follow-up (extra) treatment based on how well their cancer responds after starting targeted drugs before surgery. The goal is to improve outcomes while better matching treatment to each person’s tumor response.
Tampa, FloridaAges 18 years+ - NCT04741906Recruiting
Dental implants in people taking antiresorptive medications
This study looks at how well dental implant treatment works in people with cancer or osteoporosis who take antiresorptive medicines. It may help your team understand what to expect for healing and outcomes in your situation.
Copenhagen, DanmarkAges Any age - NCT04742608Recruiting
Liquid blood tests to diagnose thyroid nodules or cancer
This study tests whether a blood “liquid biopsy” can help diagnose thyroid cancer or hard-to-tell thyroid nodules without needing extra procedures. It may help confirm what’s going on before or around planned thyroid surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT04741945RecruitingPhase 2
Metformin to help prevent leukemia in certain blood disorders
This Phase 2 study tests whether metformin can lower the risk of leukemia developing in people with low-risk myelodysplastic syndrome (LR-MDS) or CCUS. You may be considered if your blood counts have stayed low and other causes have been ruled out.
Copenhagen, Copenhagen NAges 18 years+ - NCT04743102Recruiting
Multi-point full-thickness biopsy to confirm complete rectal cancer response
This trial checks whether taking small samples from the full thickness of rectal tissue can accurately confirm that rectal cancer has fully responded to chemotherapy and/or radiation. It may help doctors decide the best next step if no tumor is seen after treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT04743479Recruiting
AI screening for pancreatic cancer in higher-risk people
This trial uses an artificial-intelligence tool to help detect pancreatic cancer earlier and track people at higher risk. You may be asked to complete questionnaires and have imaging tests like MRI or CT to see how well the approach works.
ShanghaiAges 50–75 - NCT04743674Recruiting
Blood and urine tests to track cervical cancer after treatment
This study tests whether DNA found in blood and urine can help detect cervical cancer and monitor it after treatment. If you’re newly diagnosed, these minimally invasive samples may help doctors follow your disease more easily over time.
Chapel Hill, North CarolinaAges 18 years+ - NCT04744116RecruitingEarly Phase 1
Cord blood cell therapy added to ruxolitinib for steroid-resistant GVHD
This trial studies whether adding cord-blood–derived cells to ruxolitinib can improve steroid-resistant acute graft-versus-host disease (GVHD) affecting the lower gut or liver. It’s meant for people who are not getting better (or are worsening) despite adequate steroid treatment.
Houston, TexasAges 12–80 - NCT04744506Recruiting
Targeted removal of armpit nodes after chemotherapy for breast cancer
This trial studies a more targeted surgery to remove cancer-involved lymph nodes in the armpit after you finish chemotherapy before surgery. It may help doctors better remove affected nodes while avoiding unnecessary tissue removal.
Hangzhou, ZhejiangAges 18–85 - NCT04745403RecruitingPhase 1
Trial of redirected HBV-targeting T cells for liver cancer
This Phase 1 study tests a lab-made immune cell treatment that targets hepatitis B (HBV)–related liver cancer. It may help by directing the body’s immune system to attack the cancer, while carefully checking safety.
SingaporeAges 21–75 - NCT04745390Recruiting
Testing a tailored radiation dose plan for liver tumors
This study compares a standard radiation dose plan versus a plan that adjusts the dose based on how the tumor responds to radiation-related measurements. It aims to improve how well stereotactic body radiation therapy (SBRT) treats liver cancer while keeping side effects manageable.
