Recruiting studies
- NCT04790305RecruitingPhase 4

Hefei, AnhuiAges 18–70 - NCT04792892Recruiting
Study of quality of life after new anal cancer diagnosis
This study looks at how people’s day-to-day functioning and quality of life change after an anal cancer diagnosis. It mainly enrolls adults recently diagnosed to understand outcomes early on.
GothenburgAges 18 years+ - NCT04794777RecruitingPhase 3
Tests targeted scans and rescue radiation for returning prostate cancer
This trial studies whether a targeted scan (PSMA PET/CT) can help doctors choose the best “salvage” radiation treatment when prostate cancer comes back by PSA blood tests after surgery. It may help some people avoid under- or over-treating the areas where the cancer is returning.
Gothenburg, GöteborgAges 18 years+ - NCT04800393Recruiting
Breast surgery anesthesia and its effects on immunity and survival
This study compares two ways of giving anesthesia during breast cancer surgery to see how they affect the immune system and outcomes after surgery. It may help identify which anesthesia approach is better for people like you having early-stage, operable breast cancer surgery.
MoscowAges 45–74 - NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
Duarte, CaliforniaAges 18 years+ - NCT04804956Recruiting
Testing gut microbes and metabolites to predict rectal cancer outcomes
This study looks at patterns in the gut microbiome (gut bacteria) and gut chemicals (metabolites) to predict how rectal cancer may do after planned surgery. By understanding these markers, researchers hope to better forecast prognosis and tailor follow-up.
Girona, GironaAges 18–18 - NCT04805528Recruiting
Electrical stimulation to reduce dry mouth after head-neck radiation
This trial tests a non-invasive, acupuncture-like electrical stimulation treatment (ALTENS) to help reduce dry mouth after radiation for head and neck cancers. You may qualify if you have bothersome dry mouth and had significant head-neck radiation, with no signs of active cancer and if you can come for treatments over 12 weeks.
Rochester, New YorkAges 18 years+ - NCT04806464RecruitingPhase 1
Study drug injection for advanced liver cancer
This Phase 1 trial tests VG161, a study medicine, given by injection into liver or nearby tumors for people with advanced primary liver cancer that has not responded to standard treatment (or there is no standard option). The goal is to find a safe dose and see how the tumors respond.
Hangzhou, ZhejiangAges 18–75 - NCT04806412Recruiting
Gene testing in lung cancer fluid samples
This study looks at fluid from around the lungs (pleural fluid) to find gene changes (oncodrivers) in people with non-small cell lung cancer. The goal is to see if this fluid can replace a tissue biopsy for testing.
Næstved, Region SjællandAges 18 years+ - NCT04809324Recruiting
Testing how best to check surgical margins in oral cancer
This trial compares two ways of checking whether all oral cancer tissue was removed during surgery by looking at the tissue edges. It may help surgeons choose the safest approach to reduce the chance of cancer coming back.
Mumbai, MaharashtraAges 18–100 - NCT04814407Recruiting
Test blood and other markers to detect early lung cancer
This study looks for new “epigenetic” signals in blood (signals about how genes are turned on/off) to help detect lung cancer early. You might be able to join if you are being evaluated for possible lung cancer or have small, unclear spots on a lung CT scan.
TaipeiAges 20 years+ - NCT04817956RecruitingPhase 2
Precision-medicine treatment for advanced cancer in Norway
This Phase 2 trial tries to match people with advanced cancer to targeted treatments based on their tumor’s genetic results. It may help if standard cancer treatments are no longer working or aren’t available, and if a “target” in the tumor suggests a therapy that could work.
ÅlesundAges 16 years+ - NCT04823923Recruiting
How kidney failure affects drug levels in metastatic kidney cancer
This study looks at how chronic kidney failure changes the amount of certain cancer medicines in the blood. It involves people with metastatic clear cell kidney cancer who take pazopanib or cabozantinib, and compares drug levels in different kidney function groups.
MarseilleAges 18 years+ - NCT04827810RecruitingPhase 1
IV gamitrinib study for advanced cancers needing new options
This early-phase trial tests how safe IV gamitrinib is and how the body processes it in people with advanced cancers that can’t be controlled by standard treatment. It may also help researchers learn the best dose and whether it has signs of anti-cancer activity.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04831437RecruitingPhase 2
Tested split-course chemo radiation for cervical cancer side effects
This Phase 2 trial looks at a “split” (hypo-fractionated) schedule of chemotherapy plus radiation for cervical cancer, followed by brachytherapy. It aims to see how well the treatment works and what side effects happen, especially toxicity.
TehranAges 18–85 - NCT04838327Recruiting
Study for rare gut cancer types with targeted treatment
This study looks at rare types of gastrointestinal (GI) cancer and may match you to a targeted treatment. It also collects blood and other samples to better understand your cancer and help researchers learn what works.
Aarhus NAges 18 years+ - NCT04840056Recruiting
Testing ways to predict stomach cancer risk
This trial looks at adults with stomach lining changes—either atrophic gastritis or intestinal metaplasia—and studies how to predict who may be at risk for stomach cancer. It may help earlier identification and closer monitoring for people with these conditions.
Shatin, New TerritoriesAges 18 years+ - NCT04842006Recruiting
Personalized treatment plan for rectal cancer before and after surgery
This trial looks at a personalized treatment approach for rectal cancer. It aims to guide the best chemotherapy and (if needed) radiotherapy before and after surgery, based on scans and specific test results.
Helsinki, UusimaaAges 18–100 - NCT04842162RecruitingPhase 2
Near-infrared dye imaging to help remove all mouth/throat cancer
This Phase 2 study tests a special camera and dye during surgery to help surgeons confirm they removed all cancer at the edge of the removed tissue. If it works, it may lower the chance of cancer being left behind after oral cavity or oropharynx squamous cell cancer surgery.
AnderlechtAges 18 years+ - NCT04842916Recruiting
Study blood, tumor tissue, and preferences to predict stomach cancer response
This study looks at stomach (or stomach–esophagus junction) cancer tissue, treatment details, and patient-reported experiences to better predict how you may respond to standard chemotherapy. It may help personalize future treatment by identifying markers that connect your tumor environment and your expected outcomes.
BrestAges 18–85 - NCT04843865Recruiting
Chinese herbal add-on for joint pain from letrozole
This trial studies whether Chinese herbs, used alongside letrozole, can reduce ongoing joint and muscle pain or stiffness in postmenopausal women with hormone-receptor positive breast cancer. It’s mainly for people whose pain started or worsened after beginning letrozole and who have completed cancer treatments.
Bukit Bintang, Kuala LumpurAges 18 years+ - NCT04844528RecruitingPhase 2
Nicotinamide for CLL patients with recent skin cancer history
This Phase 2 trial tests whether nicotinamide (a form of vitamin B3) can help people with chronic lymphocytic leukemia (CLL) who have had non-melanoma skin cancers in the past 5 years. The study looks at how well new skin cancers can be prevented or reduced.
Salt Lake City, UtahAges 18 years+ - NCT04845828Recruiting
Sentinel node biopsy versus full node removal in early uterine cancer
This study compares two ways to check lymph nodes during surgery for early-stage endometrial (uterine) cancer: sentinel node biopsy versus removing more lymph nodes. It may help find whether the less extensive approach can stage the cancer accurately with fewer side effects.
SeoulAges 20–80 - NCT04846309RecruitingPhase 1
MRI scan to personalize radiation for esophageal cancer
This Phase 1 study uses specialized imaging (including MRI) to better “see” low-oxygen areas in esophageal cancer and help guide individualized radiation treatment. It aims to improve how radiation is planned and delivered while checking safety.
