Shanghai, Shanghai MunicipalityAges 18–70 - NCT05033691Recruiting
Osimertinib plus early brain radiation versus osimertinib alone
This trial tests whether starting focused radiation to brain spots early (called SRS) along with osimertinib works better than taking osimertinib alone. It is for people with lung cancer that has an EGFR mutation and has not yet caused major brain symptoms.
JerusalemAges 18–120 - NCT05034991Recruiting
Study blood flow in the uterus in endometrial cancer
This study looks at how blood flow in the uterus may relate to endometrial cancer. It may help researchers understand the disease better and guide future care.
Banqiao District, New TaipeiAges 20 years+ - NCT05037331Recruiting
Osimertinib for advanced EGFR-mutated lung cancer
This trial studies osimertinib in people with advanced or metastatic lung cancer that has specific EGFR gene changes. It aims to see how well this targeted medicine can control the cancer when surgery or radiotherapy won’t work.
SingaporeAges 21–99 - NCT05037279RecruitingPhase 3
Testing BCG treatment for bladder cancer after full tumor removal
This trial studies a BCG-based bladder instillation in people with newly diagnosed, intermediate- or high-risk non-muscle invasive bladder cancer who have had their tumor fully removed. The goal is to see whether this treatment is safer and works better to lower the chance of the cancer coming back.
Vancouver, British ColumbiaAges 18 years+ - NCT05038332RecruitingPhase 2
Testing two types of radiation after prostate surgery
This Phase 2 study compares two schedules of radiation treatment after prostate surgery in men whose PSA starts rising again. It aims to see which radiation approach works well while tracking quality of life and safety.
Ann Arbor, MichiganAges 18 years+ - NCT05041140Recruiting
Xenon MRI test for lung problems after stem cell transplant
This study uses a special MRI test with xenon gas to look at lung function in adults who had a stem cell transplant and now have breathing-related complications. It may help doctors measure lung impairment more clearly and track changes over time.
Houston, TexasAges 18 years+ - NCT05043012Recruiting
Testing a special MRI scan for prostate cancer diagnosis
This study checks how well a new prostate MRI scan (using a flexible coil and multiple MRI types) can correctly identify prostate cancer and help with treatment planning. You may be able to help doctors improve prostate imaging before you have surgery.
Houston, TexasAges 18 years+ - NCT05045066RecruitingEarly Phase 1
Vitamin D treatment study for Black men with prostate cancer
This early-phase study looks at how vitamin D replacement affects the immune system in Black/African American men with prostate cancer. It’s testing whether bringing vitamin D levels into a healthier range changes immune signals that may matter for cancer health.
Scottsdale, ArizonaAges 18 years+ - NCT05049538Recruiting
Liquid blood tests to predict endometrial cancer return
This trial studies whether blood “liquid biopsies” and tumor genetic testing can help predict whether endometrial cancer will come back after treatment. Results may help doctors plan follow-up and additional care based on a person’s recurrence risk.
Houston, TexasAges 18 years+ - NCT05051046Recruiting
Screening colonoscopy with hypnosis for colorectal cancer
This trial studies whether using hypnosis during a screening colonoscopy can help people better tolerate the procedure and complete it comfortably. It’s for adults who are scheduled for a routine screening colonoscopy and meet specific safety and communication requirements.
AngersAges 18–100 - NCT05052671Recruiting
Blood test for residual cancer in resectable pancreatic cancer
This trial studies a blood test that looks for tiny traces of cancer-related DNA (called ctDNA) in people with pancreatic cancer that can be removed with surgery. The goal is to see whether this test can better predict how the cancer behaves and guide treatment decisions around surgery.
Oklahoma City, OklahomaAges 18–99 - NCT05053997Recruiting
Support program for vulnerable people with lung cancer
This trial tests a “navigation” support program to improve survival and quality of life for people with non-small cell lung cancer who are considered vulnerable. It may help you get the right care and support more smoothly throughout treatment.
AalborgAges 18 years+ - NCT05053555Recruiting
High-dose radiation treatment for hard-to-remove liver tumors
This study uses a form of targeted radiation placed inside/near the liver to treat liver tumors that can’t be surgically removed. It’s meant to shrink or control tumors, especially when they sit near blood vessels or other sensitive organs.
Houston, TexasAges 19 years+ - NCT05054413Recruiting
Expert guideline survey for prostate cancer care
This study uses a structured expert survey to help build clear, agreed-upon guidelines for prostate cancer care. If you’re a board-certified clinician who actively treats prostate cancer, your input can help shape how care is recommended.
Houston, TexasAges 21 years+ - NCT05055648RecruitingPhase 3
Proton vs photon radiation for esophageal cancer before surgery
This trial compares proton therapy and standard photon therapy given before surgery for esophageal (or stomach–esophagus) cancer. It aims to see which radiation approach works better and is safer as part of a combined treatment plan.
LeuvenAges 18 years+ - NCT05055908RecruitingPhase 3
Testing immune-therapy for lung cancer and predicting response
This trial studies how well immune checkpoint medicines (with or without chemotherapy) work for lung cancer, and looks for biomarkers—tests that may help predict who benefits. It may help you access a structured treatment plan and additional response testing.
Changsha, HunanAges 18 years+ - NCT05057598Recruiting
Online study for women with breast cancer experiences
This study asks women with breast cancer to take part in an online, before-and-after research project. It may help researchers understand your experiences and improve support for people living with breast cancer, including those with relapse or spread to other parts of the body.
Milan, MIAges 18–90 - NCT05056857Recruiting
Study immune-web changes in ER+ breast cancer on tamoxifen
This trial studies how the immune system forms “neutrophil extracellular traps” (immune web material) in people with ER-positive breast cancer who take tamoxifen. It aims to understand whether tamoxifen changes this immune activity over time, which may help explain how it works.
Houston, TexasAges 18 years+ - NCT05058183Recruiting
Testing shorter chemotherapy for early HER2 or triple‑negative breast cancer
This study looks at whether some people with stage 1 HER2-positive or “triple-negative” breast cancer may safely need less (de-escalated) chemotherapy after surgery. The goal is to keep the cancer risk low while reducing treatment intensity, using special blood testing over time.
