Decision aid for medullary thyroid cancer treatment choices
This study tests a patient-and-caregiver decision guide to help you decide when to start or stop a new cancer drug, join a clinical trial, or continue active surveillance. It aims to make tough choices feel clearer and more supported.
Houston, TexasAges 18 years+ - NCT03933670RecruitingPhase 2
MRI scan with special sugar to monitor prostate cancer on surveillance
This study uses a special MRI scan using “hyperpolarized” labeled pyruvate (a sugar-like substance) to see how prostate cancer may be behaving in people who are on active surveillance. It may help researchers monitor cancer without immediate treatment, by spotting changes earlier.
San Francisco, CaliforniaAges 18 years+ - NCT04055220Recruiting
Regorafenib to keep bone cancer from coming back
This trial studies whether regorafenib given after first treatment helps patients with bone sarcoma stay in remission longer. It focuses on safety and whether the medicine can prevent the cancer from growing or returning.
BesançonAges 12 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 - NCT04146077Recruiting
Active monitoring for low-risk prostate cancer
This study tests whether watching low-risk prostate cancer closely (instead of treating right away) is safe. It may help some people avoid early treatments and their side effects while still keeping a close eye on the cancer.
MoscowAges 50–75 - NCT04183660Recruiting
MOBYBOX monitoring study for temporary heart-lung support
This is a post-market “real-world” monitoring study for a heart-lung machine (extracorporeal cardiopulmonary support/ECMO) used during very serious heart and/or lung failure. It aims to track safety and performance in patients who need rescue breathing or circulation support.
Hanover, Lower SaxonyAges 18–80 - NCT04239573Recruiting
Compare pancreatic cyst checkup programs and test markers
This study compares different ways to monitor pancreatic cysts and also measures blood or other test markers to see which approach is more helpful. It may help patients by finding the safest, most effective way to track certain cysts that could otherwise be hard to manage.
Birmingham, AlabamaAges 50–75 - NCT04263038RecruitingPhase 4
Watchful waiting versus blood thinners for small lung clots
This trial compares close monitoring (“watch and wait”) versus taking the blood thinner rivaroxaban in people with a small type of lung blood clot. It aims to find out whether low-risk patients can safely avoid or reduce anticoagulation while still staying healthy.
Woluwe-Saint-Lambert, Brussels CapitalAges 18 years+ - NCT04405700Recruiting
Tracking birth outcomes and birth defects after delivery
This study follows pregnant people and their babies to better measure adverse outcomes and possible congenital (from birth) conditions. It may help improve how birth risks and birth defects are identified and recorded at the clinic.
EldoretAges Any age - NCT04431024Recruiting
Testing imaging and biopsy options for people with BAP1 risk
This study looks at how well advanced scans, liquid biopsy tests, and small follow-up procedures can find early mesothelioma in people with a high-risk BAP1 gene condition. It may help catch cancer earlier when treatment could work better.
Bethesda, MarylandAges 30–120 - NCT04460352RecruitingPhase 3
Esophageal cancer treatment with chemoradiation plus planned surgery
This trial tests the best way to treat locally advanced squamous cell esophageal cancer: either chemoradiation followed by planned surgery, or monitoring with surgery only if needed. It may help you choose a strategy that controls the cancer while aiming to reduce unnecessary procedures.
Montreal, QuebecAges 18–80 - NCT04474223RecruitingPhase 3
Prevent early fetal heart rhythm problems with medicine
This study tests medicines given during pregnancy (dexamethasone and IVIG) to help prevent a type of fetal heart rhythm problem that can happen quickly. It focuses on people at higher risk based on specific blood antibody results and early pregnancy timing.
Phoenix, ArizonaAges 18 years+ - NCT04549688Recruiting
Active surveillance with focused ultrasound for prostate cancer
This trial studies whether a high-intensity focused ultrasound treatment can help people with localized prostate cancer while still avoiding traditional full-dose treatment for some patients. It may be an option for certain intermediate-risk cases where the cancer is confined to the prostate.
Tønsberg, VestfoldAges 18–80 - NCT04585490RecruitingPhase 3
Testing a personalized add-on treatment after stage III lung cancer
This phase 3 trial tests whether tailoring the next (add-on) treatments can improve outcomes after standard chemoradiation and immunotherapy for stage III, unresectable (not operable) non-small cell lung cancer. It specifically looks at giving durvalumab plus an additional drug (tremelimumab) and possibly other consolidation chemotherapy based on a personalized plan.
Stanford, CaliforniaAges 18 years+ - NCT04613570Recruiting
Follow-up endoscopy plan for early stomach changes
This study looks at how often and how intensely to do follow-up stomach camera exams (endoscopy) with small biopsies for people at risk of stomach cancer. It may help personalize your follow-up schedule based on your specific stomach findings.
PortoAges 45 years+ - NCT04624555Recruiting
Check how well stool DNA tests help watch for colon cancer return
This trial studies whether an at-home stool DNA test (Mt-sDNA) can safely and usefully monitor people after colon or rectal cancer treatment. It’s mainly about whether the test is practical and helpful during routine follow-up.
Cleveland, OhioAges 18 years+ - NCT04634916Recruiting
Check how a dialysis fistula device performs in real life
This study monitors how well the BD WavelinQ endoAVF device works after routine clinical use. It may help people who need a dialysis access fistula by sharing real-world safety and performance data.
La Jolla, CaliforniaAges 18 years+ - NCT04692675Recruiting
MRI study to track prostate cancer in active surveillance patients
This study uses special prostate MRI scans to see how prostate cancer changes over time while you stay on active surveillance. It also looks at prostate tissue to understand your cancer’s genetics, which may help guide future decisions.
Bethesda, MarylandAges 18 years+ - NCT04703101RecruitingPhase 1
Short radiation plus chemo for stage II–III rectal cancer
This trial tests a short course of radiation therapy combined with chemotherapy for people with stage II or III rectal cancer. It’s designed to see whether this approach is safe and effective before or around cancer surgery.
Los Angeles, CaliforniaAges 18 years+ - 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.
