Rochester, MinnesotaAges 18 years+ - NCT04660435Recruiting
Study how breast cancers resist CDK4/6 inhibitor treatment
This study looks at why some ER-positive, HER2-negative metastatic breast cancers don’t respond well to CDK4/6 inhibitors combined with hormone therapy. It may help researchers understand resistance and improve future treatment choices for people like you.
Prato, TuscanyAges Any age - NCT04683679RecruitingPhase 2
Radiation plus pembrolizumab and olaparib for certain breast cancers
This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04495244Recruiting
Identifying breast cancer through a blood test
This study tests a blood test designed to help find breast cancer. It may help detect the disease earlier, which could make treatment more effective.
Calgary, AlbertaAges 30–75 - NCT04585750RecruitingPhase 1/Phase 2
Studying a new drug for cancers with a specific TP53 change
This trial tests a new drug (rezatapopt) for people with advanced cancers that have a specific change in the TP53 gene, called Y220C. The drug is designed to target this change and may slow or stop cancer growth. Some participants may also receive an immunotherapy drug called pembrolizumab (Keytruda).
Irvine, CaliforniaAges 12 years+ - NCT04589468Recruiting
Exercise for cancer survivors at high risk
This study tests whether a structured exercise program can help prevent cancer from coming back in people who have been treated for certain solid tumors (colorectal, ovarian, lung, or breast cancer). If you've completed surgery and adjuvant therapy within the past 2 years and are currently not exercising much, you may be eligible. Participation involves following an exercise plan and regular check-ins.
Durate, CaliforniaAges 18 years+ - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04501419Recruiting
Mobile ultrasound test to help diagnose breast cancer
This study checks whether a tablet-based ultrasound can find breast lumps that look suspicious for cancer. If it works well, it could help diagnose breast cancer faster in Nigeria where patients may need a biopsy or surgery next.
Ile-IfeAges 18 years+ - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04348747RecruitingPhase 2
Vaccine plus pembrolizumab for breast cancer in the brain
This trial studies whether a personalized immune-cell vaccine (dendritic cell vaccine) combined with pembrolizumab can help control brain metastases from certain types of breast cancer. It may help your immune system better recognize and attack cancer cells in the brain.
Tampa, FloridaAges 18 years+ - NCT04360330Recruiting
MRI study in early breast cancer with specific lab markers
This study tests selected treatment decisions for women with early-stage breast cancer that has certain lab test results. It may help researchers better match care using MRI and tumor marker information.
Miami, FloridaAges 50 years+ - NCT04362826Recruiting
Probiotic supplement study for breast cancer patients
This study tests whether taking a probiotic supplement affects the bacteria and fungi in your gut, which may be linked to your breast cancer. You'll take a daily probiotic and have your diet and activity stay the same, to see if it helps your body respond to treatment.
Cleveland, OhioAges 18–65 - NCT04234386Recruiting
Short-course targeted radiation for early breast cancer
This trial tests a radiation plan called GammaPod to treat early breast cancer with precise targeting. It may help patients by delivering the treatment in a more focused way, while checking safety and tumor control in the smallest, well-defined cancers.
Baltimore, MarylandAges 45 years+ - NCT04230109RecruitingPhase 2
Sacituzumab Govitecan for newly diagnosed TNBC
This trial tests a drug called sacituzumab govitecan for people with newly diagnosed triple-negative breast cancer (TNBC) that hasn't been treated yet. The drug targets cancer cells directly to try to stop them from growing.
Boston, MassachusettsAges 18 years+ - NCT04150042RecruitingPhase 1
Test of chemotherapy plus your own stem cells for metastatic cancer
This Phase 1 trial tests a treatment approach using standard chemotherapy along with stem cells taken from you to treat metastatic pancreatic or breast cancer. It is mainly designed to check safety and find the best way to give the treatment, and it may offer an option for people whose cancer has spread.
Boston, MassachusettsAges 18 years+ - NCT04038619RecruitingPhase 1
Fecal transplant for immune-therapy diarrhea or bowel inflammation
This early-phase study tests whether stool/fecal microbiota transplant (a fecal transplant) can help people who develop significant diarrhea or colitis after immune-checkpoint therapy. It aims to reduce bowel inflammation and improve symptoms, while carefully checking for infections.
Houston, TexasAges 18 years+ - NCT03941756Recruiting
Lymph bypass before underarm node surgery to prevent swelling
This study looks at whether adding a lymph “bypass” procedure before underarm lymph node surgery can lower the chance of arm or chest swelling (lymphedema) after cancer treatment. It compares people having lymph node surgery for breast cancer with plans for radiation, and a melanoma comparison group.
Houston, TexasAges 18 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03606967RecruitingPhase 2
Individualized vaccine added to standard treatment for metastatic triple-negative breast cancer
