Testing how added radiation may work by immune and tumor markers
This study looks at people with non-metastatic invasive breast cancer who are getting curative breast surgery followed by planned radiation (sometimes with other anti-cancer medicines). Researchers want to understand whether a patient’s age and certain immune/tumor blood features can predict how well radiation helps.
JenaAges 18 years+ - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT07478900Recruiting
Tattoo marking breast tumors before chemo
This trial tests a simple method: marking the tumor with a small tattoo before chemotherapy. The tattoo helps surgeons find the exact spot for lumpectomy after the tumor shrinks, so you can keep more of your breast.
Bhubaneswar, OdishaAges 18–75 - NCT07383506RecruitingPhase 1
Study of a targeted pill for PIK3CA-mutated advanced cancers
This trial tests a new pill (CGT6297) that targets cancer cells with a specific PIK3CA gene change. It may be an option for people with certain advanced solid tumors, including endometrial or breast cancer, after standard treatments have stopped working.
Scottsdale, ArizonaAges 18 years+ - 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+ - NCT05404321Recruiting
Collecting tumor samples to study triple-negative breast cancer treatments
This study collects tumor tissue from people with early-stage triple-negative breast cancer before they start neoadjuvant chemotherapy. The goal is to help researchers test new therapies and look for markers that may predict who benefits.
CaenAges 18 years+ - NCT06784193RecruitingPhase 1
Study of OP-3136 for advanced solid tumors
This trial tests a new drug, OP-3136, alone or with other drugs, for people with advanced breast cancer, prostate cancer, or lung cancer that has stopped responding to other treatments. It aims to see if OP-3136 is safe and effective.
Sarasota, FloridaAges 18 years+ - NCT04389281RecruitingPhase 1
X-ray light-activated therapy for hard-to-treat skin tumors
This early-phase study tests an X-ray–activated medicine that is delivered directly into selected tumors to help control cancer that has not responded to standard treatments. If the injected area can be treated safely, it may shrink or slow the tumor and improve local control.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04601116RecruitingPhase 3
Atorvastatin for hormone-positive breast cancer to prevent recurrence
This Phase 3 study tests whether taking atorvastatin (a cholesterol-lowering medicine) can improve outcomes for women with estrogen-receptor–positive breast cancer. It may help by affecting cancer-related pathways and reducing risk of recurrence or progression.
AarhusAges 18 years+ - NCT05746897RecruitingPhase 1
First-in-human test of an anti-PVRIG drug for advanced cancers
This early-phase study tests NM1F (an anti-PVRIG antibody) in people with advanced solid tumors to see if it’s safe and whether it may work. It also includes pembrolizumab (a PD-1 “checkpoint” medicine), aiming to boost the immune system against the cancer.
Dallas, TexasAges 18 years+ - NCT07084558Recruiting
Testing treatment guided by tumor DNA for hormone positive breast cancer
This trial tests whether using a blood test (circulating tumor DNA) can help guide chemo and hormone therapy for early-stage, hormone receptor positive and HER2 negative breast cancer. The goal is to tailor treatment to your tumor's response, potentially reducing unnecessary side effects.
Vienna, AustriaAges 18–100 - NCT05896865Recruiting
Personalized breast cancer radiation based on tumor biology
This trial studies whether adjusting radiation dose using how the tumor behaves can improve outcomes for people with locally advanced breast cancer that has spread to certain nearby lymph nodes. It may help deliver the right radiation intensity while avoiding unnecessary exposure.
SeoulAges 19 years+ - NCT04354064Recruiting
Blood DNA test to see early treatment response in solid tumors
This study looks at circulating tumor DNA, which is tiny bits of DNA found in blood, to help assess how solid tumors are responding early. It uses blood samples from healthy adults who are willing to donate.
St Louis, MissouriAges 18 years+ - NCT01789229Recruiting
Tumor and inflammation sample bank for one specific condition
This study builds a secure “tumor sample bank” using tissue collected from people who currently have one diagnosed condition, either cancer (malignant disease) or an ongoing inflammatory condition. Your samples could help researchers study your disease and develop better treatments in the future.
ViennaAges 18 years+ - NCT04065321Recruiting
Blood test for tumor cells in certain early breast cancers
This trial looks at a blood test that may detect “circulating tumor cells” (cancer cells that can travel in the bloodstream) in people with a specific type of breast cancer. It may help doctors better track the disease and guide treatment for people whose tumors have certain hormone and growth-factor features.
Shenyang, LiaoningAges 18–60 - NCT06222879RecruitingPhase 1/Phase 2
New drug combinations for advanced breast cancer
This trial tests a combination of new drugs (HRS-8080, SHR-A2009, or others) for people with advanced breast cancer that has stopped responding to previous treatments. The goal is to see if these combinations can shrink tumors or slow the cancer's growth.
Changsha, HunanAges 18–75 - NCT01441089Recruiting
Donate blood for genetic testing in an NIH research study
This study collects blood from people already in an NIH (National Institutes of Health) clinical research program to run genetic tests. It may help researchers understand cancer and related inherited conditions by studying DNA changes.
Bethesda, MarylandAges 3 years+ - NCT07327489Recruiting
