Kansas City, KansasAges 30–65 - NCT00722228RecruitingPhase 1/Phase 2
Cancer vaccine made from your cells or a donor
This early-phase trial tests a whole-cell cancer vaccine for people with certain metastatic cancers. It aims to help your immune system recognize and fight the cancer, especially when prior chemotherapy hasn’t worked.
JerusalemAges 18 years+ - NCT01174121RecruitingPhase 2
Immunotherapy made from your tumor-fighting immune cells
This trial tests a treatment made from your own immune cells (called tumor-infiltrating lymphocytes, or TILs) for certain metastatic cancers. It’s designed for people whose cancer has not responded to standard treatments and who can safely provide a small tumor sample for cell-making.
Bethesda, MarylandAges 18–72 - NCT01840293Recruiting
Breast cancer study using tumor tissue to find key differences
This trial looks at breast cancer “proteins” and molecular features using tumor samples taken during surgery or biopsy. The goal is to better understand why breast cancers behave differently, which may help guide more personalized treatment in the future.
CorkAges 18 years+ - NCT01993498Recruiting
Study side effects of cancer treatment in localized breast or lung cancer
This study looks at long-term side effects from standard cancer treatments and how they affect daily life and resources. It may help improve care for people with breast or lung cancer that has not spread.
VillejuifAges 18 years+ - NCT02732860Recruiting
Test your tumor’s drug response using a lab model
This trial grows a lab model from your own tumor tissue (or resected tissue) to predict which drugs might work best. It’s meant to match investigational treatments to your specific tumor biology.
Toronto, OntarioAges 18 years+ - NCT02338167Recruiting
Study for pregnant women with breast cancer
This study is for adults with breast cancer who are pregnant and are either newly diagnosed (early) or have locally advanced or metastatic disease. It aims to better understand how breast cancer treatment should be managed during pregnancy.
Böblingen, Baden-WurttembergAges 18–99 - NCT02422641RecruitingPhase 2
High-dose methotrexate for breast cancer in the brain lining
This Phase 2 trial tests whether giving high-dose methotrexate into the bloodstream can help treat breast cancer that has spread to the thin lining covering the brain and spinal cord. It may help reduce cancer in the leptomeningeal (brain-lining) area and control symptoms.
Baltimore, MarylandAges 18 years+ - NCT02819882Recruiting
Registry study for advanced or metastatic breast cancer
This study collects health and treatment information from people with breast cancer that cannot be fully removed by surgery or that has spread to other parts of the body. It may help researchers better understand which treatments are used and how people do over time.
Elche, AlicanteAges 18 years+ - NCT02926690RecruitingPhase 1
MELK inhibitor safety study for advanced breast cancer
This Phase 1 study tests how safe a drug called an MELK inhibitor is in people with advanced breast cancer that has spread or cannot be removed with surgery. If you qualify, the study is focused on side effects and includes a special group for triple-negative breast cancer.
Norwalk, ConnecticutAges 18 years+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Gilbert, ArizonaAges 30 years+ - NCT06417801Recruiting
Study of ESR1 gene changes in blood in advanced breast cancer
This study looks for changes in the ESR1 gene in the blood of people with advanced HR+/HER2- breast cancer. It compares these blood test results with tumor tissue results to learn more about the cancer.
Salvador, Estado de BahiaAges 18–100 - NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.
ShanghaiAges 18 years+ - NCT00068003Enrolling by invitation
Harvesting Cancer Cells for Experimental Treatment
This trial collects immune cells from cancer patients or healthy volunteers to develop new experimental cancer treatments. Researchers will take a sample of your tumor or blood cells, grow them in the lab, and study how to use them to fight your cancer.
Bethesda, MarylandAges 18 years+ - NCT07401537RecruitingPhase 2
Comparing two schedules of immunotherapy for advanced triple-negative breast cancer
This trial tests whether giving immunotherapy less often (extended dose intervals) works as well as the standard schedule for people with advanced triple-negative breast cancer who have already completed 6 cycles of first-line treatment. It aims to see if a longer break between doses can be just as effective with fewer hospital visits.
Guangzhou, GuangdongAges 18–70 - NCT07410494RecruitingPhase 1/Phase 2
Personalized donor cell therapy for advanced solid tumors
This trial tests a personalized cell therapy (CAR-NK) using donor immune cells that are engineered to find and attack one or two markers on advanced solid tumors. It may be an option for people whose tumors have these specific markers and have exhausted other treatments.
