StrasbourgAges 18 years+ - 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+ - NCT04529044RecruitingPhase 2
177Lu-DOTATATE for advanced breast cancer with targeted receptors
This Phase 2 trial tests whether 177Lu-DOTATATE can slow or shrink stage IV or recurrent breast cancer. It targets tumor “receptors” found on scans, using a radioactive medicine that delivers radiation directly to cancer cells.
Portland, OregonAges 18–100 - NCT04517838Recruiting
Testing immune responses to anti-HER2 breast cancer treatments
This study looks at how your immune system reacts to anti-HER2 treatments in people with HER2-positive breast cancer. It may help doctors understand who responds best by studying immune signals in blood (and sometimes tissue) during or after treatment.
Jacksonville, FloridaAges 18 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+ - NCT04517266Recruiting
Testing less radiation to the inner breast area
This trial studies whether some patients with early-stage breast cancer can safely skip a specific part of radiation to the inner chest (called internal mammary irradiation). It may reduce radiation side effects while still aiming to prevent the cancer from coming back.
Shanghai, Shanghai MunicipalityAges 18–80 - 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+ - NCT04521764RecruitingPhase 1
Vaccine for Metastatic Breast Cancer
This trial tests a vaccine (MV-s-NAP) that is injected directly into a tumor to stimulate your immune system against breast cancer. It is for people with metastatic breast cancer that has spread despite prior treatments.
Rochester, MinnesotaAges 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+ - NCT04400695RecruitingPhase 3
Targeted drug for breast cancer with low HER2 levels
This trial tests a new drug that targets breast cancer cells with low levels of the HER2 protein. It may offer a new treatment option for patients whose cancer has spread and not responded well to previous therapies.
Beijing, Beijing MunicipalityAges 18–70 - NCT04332588RecruitingPhase 1
Testing PET/MRI monitoring for HER2-positive breast cancer before surgery
This early-phase study looks at how well PET/MRI scans can monitor treatment response in people with HER2-positive breast cancer before surgery. You may be asked to undergo specific scans during “neoadjuvant” therapy (treatment given before the main operation).
Birmingham, AlabamaAges 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+ - NCT04329065RecruitingPhase 2
Vaccine with targeted breast cancer drugs before surgery
This Phase 2 trial tests whether adding a cancer vaccine (with GM-CSF) to standard HER2-targeted chemotherapy before surgery improves treatment outcomes for HER2-positive breast cancer. If you join, you’ll receive planned medicine before surgery to treat the tumor, then continue with the study schedule.
Seattle, WashingtonAges 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+ - 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+ - NCT04084730RecruitingPhase 2
3-day radiation after breast-conserving surgery for certain breast cancers
This trial tests whether a shorter, 3-day course of partial breast radiation after surgery works as well as standard radiation for women with early-stage breast cancer. It may help reduce time in treatment while aiming to keep cancer from coming back in the treated breast area.
Norwalk, ConnecticutAges 45 years+ - NCT04090567RecruitingPhase 2
Olaparib with two partners for advanced BRCA breast cancer
This trial tests whether the drug olaparib works better when combined with cediranib or AZD6738 in people with advanced or metastatic BRCA (inherited) breast cancer. It may help shrink tumors or slow cancer growth after prior treatment with a PARP inhibitor.
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
This Phase 2 trial tests whether adding a personalized cancer vaccine to durvalumab (an immunotherapy), tremelimumab (another immunotherapy), and chemotherapy can improve outcomes for people with metastatic triple-negative breast cancer. It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 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
