Tucatinib plus oral chemo and trastuzumab for metastatic HER2+ breast cancer
This Phase 2 trial studies tucatinib combined with oral etoposide and trastuzumab in people with metastatic HER2-positive breast cancer, aiming to slow cancer growth. You may be eligible if you previously had progression on a similar HER2-targeted treatment or cannot take capecitabine for medical reasons.
Clermont-Ferrand, Clermont FerrandAges 18 years+ - NCT06693323RecruitingPhase 2
AHCC supplement with standard therapy for HPV-related head and neck cancer
This trial tests whether adding an AHCC supplement to standard treatment can improve outcomes for people with HPV-positive head and neck cancer. It is for patients who have had surgery and have certain high-risk features, like positive margins or cancer spread to lymph nodes.
Orange, CaliforniaAges 18–79 - NCT06888843RecruitingPhase 2
Chemotherapy for colorectal cancer in patients 70+
This trial tests two chemotherapy drugs, capecitabine alone or with oxaliplatin, in people aged 70 or older after surgery for stage III colorectal cancer. The goal is to find out which treatment works better to prevent cancer from coming back.
Nizhny NovgorodAges 70–90 - NCT04852588Recruiting
Sample chest lymph nodes during treatment for advanced lung cancer
This study checks lymph nodes in the chest (using a camera-guided test) in people with advanced non-small cell lung cancer who are getting curative-intent radiation. The trial may help doctors better confirm how far the cancer has spread and guide the best radiation treatment plan.
London, OntarioAges 18 years+ - NCT04570553Recruiting
Testing a tool during surgery for early endometrial cancer
This study looks at how well a surgical tool is used during standard surgery for early endometrial cancer, and whether it relates to test results from fluid taken in the abdomen. It may help surgeons improve how samples are collected and interpreted during routine care.
York, PennsylvaniaAges 18 years+ - NCT03861507Recruiting
Power ultrasound helps locate prostate treatment needles
This trial studies whether a special ultrasound method (power Doppler ultrasound) can better guide where needles go during high-dose-rate radiation treatment for prostate cancer. The goal is to improve targeting during the procedure while you receive standard treatment.
London, OntarioAges 18 years+ - NCT04506008RecruitingPhase 2
Radiation followed by surgery for soft tissue sarcoma
This trial tests a treatment plan where you first get a shorter (hypofractionated) course of radiation and then have surgery to remove the tumor. It may help control the cancer locally in certain soft tissue sarcomas and improve surgical outcomes.
Nashville, TennesseeAges 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 - NCT06464471Recruiting
Health assessment before non-cancer surgery for seniors
This study checks if a special health assessment helps improve recovery for patients aged 70 and older who are having surgery for a non-cancer condition. The assessment looks at overall well-being to help your medical team plan your care.
Toronto, OntarioAges 70 years+ - NCT06594679RecruitingPhase 1/Phase 2
Study of niraparib and abemaciclib for advanced ovarian cancer
This trial tests a combination of two targeted drugs, niraparib and abemaciclib, for people with ovarian, fallopian tube, or primary peritoneal cancer that has come back after at least two prior chemotherapies. It may be an option if you have no standard treatments left and your cancer still responds to platinum-based chemotherapy.
Milan, MilanoAges 18 years+ - NCT06899581Recruiting
Gut health study for children with cancer
This study looks at gut health in children with certain cancers. It may help researchers understand how to better support children during treatment.
LondonAges 1 month–16 years - NCT06899789Recruiting
Long-term follow-up of colitis from checkpoint inhibitors
This study follows people who developed colitis (inflammation in the colon) after receiving immune checkpoint inhibitors for cancer. Researchers want to learn about long-term effects and outcomes.
Pavia, PaviaAges 18 years+ - NCT05483400RecruitingPhase 2
Atezolizumab and tiragolumab study for several solid tumors
This Phase 2 trial tests the cancer medicines atezolizumab and tiragolumab in people with different solid tumors. It aims to see how well these drugs work and what side effects they cause in specific patient groups.
GroningenAges 18 years+ - NCT03844360RecruitingPhase 4
Personalized dosing of cancer or infection medicines in children
This trial looks at how to adjust the dose of cancer medicines and/or anti-infection medicines in children who have blood-related cancers. The goal is to make dosing fit each child’s needs while they receive standard treatment.

TU2218 with Keytruda for advanced solid tumors
This trial studies TU2218 taken with Keytruda (pembrolizumab) in adults with advanced solid cancers that have limited treatment options. The goal is to see if the combination can shrink tumors and is safe enough to keep using.
San Antonio, TexasAges 18 years+ - NCT05460507RecruitingPhase 1
Re-treating brain tumor with radioactive liposome after prior dose
This Phase 1 trial tests whether a radioactive treatment delivered in tiny fat “packets” is safe and tolerable when given again to people whose glioma (brain tumor) came back after a previous similar treatment. It also looks at how well this re-treatment works in carefully selected patients.
San Antonio, TexasAges 18 years+ - NCT05344235Recruiting
Study of very short radiation schedules for prostate cancer
This observational study looks at how well men with localized prostate cancer do when treated with an unusually short radiation approach. It may help doctors understand which patients benefit most by tracking outcomes and imaging over time.
Leuven, Vlaams BrabantAges Any age - NCT06111807Recruiting
Validating blood tests for stage III lung cancer
This trial is testing whether new blood tests can reliably detect and monitor stage III non-small cell lung cancer (NSCLC). It hopes to improve how doctors track your cancer and decide on treatment.
Nice, NiceAges 18 years+ - NCT06221553RecruitingPhase 1
New CAR T-cell treatment for DIPG brain tumor
This trial tests a new type of immunotherapy called B7H3 IL-7Ra CAR T-cells for children with DIPG, a tough-to-treat brain tumor. The treatment is given directly into the fluid around the brain using a special catheter, and the goal is to see if it's safe and if it can help fight the tumor.
