St Louis, MissouriAges 18 years+ - NCT07137416RecruitingPhase 1
Testing a new combination of cancer drugs for HER2-positive tumors and breast cancer
This trial tests the safety of combining two drugs, CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd), in people with HER2-positive solid tumors or certain types of breast cancer. If you have advanced cancer that hasn't responded to other treatments, this study may be an option.
St Louis, MissouriAges 18 years+ - NCT05505643Recruiting
Cryoablation versus lumpectomy for early breast cancer
This trial compares two ways to remove early-stage breast tumors: freezing (cryoablation) or surgery (lumpectomy). It may help find which option works as well or better for cancer control while keeping the breast looking more natural for some people.
St Louis, MissouriAges 50 years+ - NCT07174336RecruitingPhase 3
Testing Tersolisib with other treatments for advanced breast cancer
This trial tests a new study drug called Tersolisib combined with other anti-cancer treatments for people with advanced breast cancer that has a specific gene change (PIK3CA). The goal is to see if the combination can help shrink or slow the cancer.
Kansas City, MissouriAges 18 years+ - NCT06120283RecruitingPhase 1
Testing a new drug for breast cancer and other solid tumors
This trial tests a new oral drug (BGB-43395) alone or with other treatments for people with advanced breast cancer or other solid tumors that depend on CDK4. It aims to find safe doses and see if the drug helps shrink tumors or slow growth.
St Louis, MissouriAges 18 years+ - NCT07173751RecruitingPhase 3
Pumitamig for advanced triple-negative breast cancer
This study tests a new drug called pumitamig for people with a type of breast cancer that is triple-negative or has very low hormone receptors and has come back or spread. It aims to see if pumitamig works better than standard treatment and how safe it is for people who cannot get PD(L)-1 immunotherapy with chemo.
Kansas City, MissouriAges 18 years+ - NCT07287098RecruitingPhase 2
Imlunestrant for premenopausal women with ER+/HER2- early breast cancer
This trial tests a new hormone-blocking pill (imlunestrant) in premenopausal women with early-stage ER+/HER2- breast cancer. Depending on whether you've had prior hormone therapy, the study will see if this treatment works better than standard options.
St Louis, MissouriAges 18 years+ - NCT00353483Recruiting
Testing treatment before or after breast cancer surgery
This trial studies how different cancer treatments given before or after standard therapy affect breast cancer cells in the blood and bone marrow. It may help doctors better understand how treatments work throughout the body, not just where the tumor is.
St Louis, MissouriAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Ballwin, MissouriAges 40–75 - NCT06312176RecruitingPhase 3
Study of new drugs for HR+/HER2- advanced breast cancer
This trial tests two new drugs (sacituzumab tirumotecan and pembrolizumab) against standard treatments for a type of advanced breast cancer that is hormone receptor positive and HER2 negative. It's for people whose cancer has worsened despite hormone therapy with a CDK4/6 inhibitor.
Kansas City, MissouriAges 18 years+ - NCT07046923RecruitingPhase 1
A study of LY4175408 for advanced cancer
This trial tests a new targeted drug (LY4175408) for people with certain advanced solid tumors (lung, endometrial, or triple negative breast cancer) who have already tried standard treatments. The goal is to see if the drug is safe and effective.
St Louis, MissouriAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 3
Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Kansas City, MissouriAges 18 years+ - NCT06465069RecruitingPhase 1
Study of a new drug for advanced bladder and other solid tumors

Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
St Louis, MissouriAges 18 years+ - NCT06500481RecruitingPhase 3
Proton vs standard radiation for cancer spread to brain/spine lining
This trial compares a newer type of radiation (proton therapy) to standard radiation for people whose breast or lung cancer has spread to the lining of the brain and spinal cord. It aims to see if proton therapy can better control the disease while causing fewer side effects.
City of Saint Peters, MissouriAges 18 years+ - NCT06995898Recruiting
Blood test study for early cancer detection

What taking part in a breast neoplasms study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
