- NCT04442412RecruitingPhase 3
Prednisone and vitamin D before chemo for certain lymphomas
This Phase 3 study tests whether a short “pre-treatment” with prednisone, with or without vitamin D, can improve outcomes when followed by standard lymphoma chemo. It aims to see if adding vitamin D early can help older adults tolerate or benefit from treatment for specific lymphoma types.
Brescia, BSAges 65 years+ - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.
AntwerpAges 18–100 - NCT04443088RecruitingPhase 1
Study drug INV-1120 with or without pembrolizumab for advanced cancers
This Phase 1 trial studies INV-1120 alone and with pembrolizumab (an immune therapy) in adults with advanced solid tumors that have stopped responding to standard treatment or have no standard option. The goal is to see how the treatments work, what dose is safest, and what side effects may occur.
Lafayette, IndianaAges 18 years+ - NCT04442516Recruiting
Testing kidney injury risk from cisplatin cancer treatment
This study looks at how cisplatin chemotherapy affects the kidneys. It may help doctors better predict and protect against kidney damage when patients start cisplatin.
London, OntarioAges 3 months+ - NCT04442724Recruiting
MRI and bladder marker planning to guide bladder chemoradiation
This trial uses special MRI scans and tiny markers placed in the bladder to better plan bladder chemoradiation. The goal is to help target treatment more accurately and improve how well it can be delivered.
Los Angeles, CaliforniaAges 18 years+ - NCT04443010RecruitingPhase 1/Phase 2
Testing a new protein drug with standard treatment for new glioblastoma
This Phase 1/2 study tests whether adding a drug called L19TNF to standard chemoradiotherapy is safe and may work better than standard treatment alone for newly diagnosed glioblastoma. If you qualify, you would be closely monitored for side effects and treatment response.
ZurichAges 18 years+ - NCT04443478Recruiting
Keyhole versus open lymph node surgery for junction cancer
This trial compares two ways of removing lymph nodes during surgery: keyhole (laparoscopic) versus open surgery. It is for people with esophagus-stomach junction adenocarcinoma, aiming to see which approach works better and is safer.
Beijing, Beijing MunicipalityAges 18–80 - NCT04444869RecruitingPhase 2
Lower-dose radiation with chemotherapy for low-risk HPV throat cancer
This trial tests whether a less intense (lower-dose) radiation plan, combined with chemotherapy, can control HPV-positive oropharyngeal (throat) cancer with fewer side effects. It targets people considered “low-risk” based on tumor size and lymph node involvement.
Columbia, MissouriAges 18 years+ - NCT04447352RecruitingPhase 3
HIPEC plus FLOT versus FLOT alone for gastric or GE junction cancer
This trial compares two treatment approaches after your stomach/GE junction cancer has been treated with chemotherapy before surgery: adding a special heated bath into the abdomen (HIPEC) plus continuing the usual surgery plan. It aims to see if adding HIPEC lowers cancer coming back and improves outcomes.
AachenAges 18–75 - NCT04448184RecruitingPhase 3
Platelet transfusion strategy during stem cell transplant
This trial compares how platelets are given during a stem cell transplant to help prevent bleeding. It also watches for clotting risks, since platelets can affect both bleeding and clot formation.
Calgary, AlbertaAges 18 years+ - NCT04448522RecruitingPhase 3
Lower-dose radiotherapy for EBV-responsive nasopharyngeal cancer
This Phase 3 study tests whether giving a reduced amount of radiotherapy can work as well as the standard dose for certain people with stage II–III nasopharyngeal cancer who respond well after initial chemotherapy. It’s designed for patients whose cancer markers improve after 3 chemotherapy cycles, to potentially reduce treatment side effects while keeping cancer control.
Guangzhou, GuangdongAges 18–70 - NCT04450758Recruiting
Stent or stoma right away versus surgery later for bowel blockage
This trial studies treatment choices for adults with a large-bowel blockage caused by colon cancer. It compares doing an emergency procedure now (like a stent or stoma) versus bridging to a later colon surgery, to see which approach is safer and works better.
GothenburgAges 18–100 - NCT04451473Recruiting
Compare recovery programs after lung surgery
This trial compares two ways of helping patients recover after lung surgery: a “enhanced recovery” plan versus standard care. It may help your team find a recovery approach that improves comfort and recovery after surgery for certain lung problems.
Jinan, ShandongAges 18–85 - NCT04452305Recruiting
Frozen testicle tissue transplant to restore fertility
This study tests using previously frozen (cryopreserved) testicle cells or tissue to regrow testicular tissue. If you’ve had cancer treatment that can harm fertility, this may help restore natural fertility potential using your own tissue.
Pittsburgh, PennsylvaniaAges Any age - NCT04452162Recruiting
MRI study for salivary gland tumors
This trial uses special MRI scans to learn how salivary gland tumors work in the body. It may help improve diagnosis and how tumors are evaluated without needing treatment yet.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04452825Recruiting
Psychotherapy for older adults with cancer distress
This trial studies a new talking-therapy program for people age 70+ who have cancer and feel emotional distress. It may help reduce anxiety and low mood while you’re receiving cancer treatment or followed closely after treatment.
New York, New YorkAges 70 years+ - NCT04458792Recruiting
Builds a cancer blood-and-biomarker database after sarcoma treatment
This study collects information and blood samples from adults with sarcoma who had surgery and possibly radiation. The goal is to build a large dataset that helps researchers understand sarcoma better and improve future care.
Montpellier, HeraultAges 18 years+ - NCT04453826RecruitingPhase 3
Test PD-1 plus chemo-radiation for high-risk nasopharyngeal cancer
This Phase 3 trial tests whether adding a PD-1 immunotherapy (given with chemotherapy and radiation, and also after) can improve outcomes for people with high-risk nasopharyngeal cancer. It may help by strengthening the immune system’s attack on the cancer alongside standard treatment.
Guangzhou, GuangdongAges 18–70 - NCT04453072Recruiting
iPhone weight-loss app for teens and young adults after transplant
This study tests whether an iPhone weight-management app can help adolescents and young adults lose weight after a stem cell transplant. If you qualify, you’ll use the app and the team will track changes in weight.
Los Angeles, CaliforniaAges 13–30 - NCT04453813RecruitingPhase 3
Immunotherapy with chemoradiation for recurring nasopharyngeal cancer
This phase 3 trial tests whether adding toripalimab (an immunotherapy medicine) to standard chemo-radiation works better for treating nasopharyngeal cancer that has come back and cannot be removed by surgery. It aims to improve control of the cancer after it returns.
Guangzhou, GuangdongAges 18–70 - NCT04453904Recruiting
Testing best added chemo and radiation after stage III uterine cancer
This study compares different ways of giving radiation and chemotherapy after surgery for stage III endometrial (uterine) cancer. It aims to find which approach works best to reduce cancer risk and improve outcomes.
Beijing, Beijing MunicipalityAges Any age - NCT04455282Recruiting
Blood test-guided surgery for gastroesophageal cancer
This trial studies blood-based biomarkers to help doctors choose the best individualized surgical treatment for gastroesophageal junction adenocarcinoma. If you qualify, you’ll get standard care plus additional testing to see whether the blood results can guide surgery more precisely.
Cologne, North Rhine-WestphaliaAges 18 years+ - NCT04455932Recruiting
Test shorter MRI versus ultrasound for liver cancer screening
This study compares a shorter, non-contrast MRI and ultrasound to monitor for liver cancer in people with cirrhosis whose ultrasound images aren’t clear enough. It aims to see which method works better and may help you get safer, more reliable follow-up.
Camperdown, New South WalesAges 20–85 - NCT04457713Recruiting
Study of off-label anti-cancer drugs in adults
This study follows adults with cancer who are receiving anti-cancer medicines that are being used “off-label” (not exactly as the usual label says). It aims to learn about how these treatments are used in real life and what outcomes people experience.
