- NCT06058377RecruitingPhase 3
Adding immunotherapy to chemo for stage II-III breast cancer

St Louis, MissouriAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
St Louis, MissouriAges 18 years+ - NCT07115043RecruitingPhase 1/Phase 2
Study of AZD6750 for advanced solid tumors
This trial tests a new drug called AZD6750 for people with advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
St Louis, MissouriAges 18 years+ - NCT06995898Recruiting
Blood test study for early cancer detection
This study is testing a new blood test that may help find cancer early. You will give blood samples over a year, and researchers will check them for signs of cancer.
St Louis, MissouriAges 45–75 - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors

Pembrolizumab versus monitoring after triple-negative breast cancer response
This trial checks whether giving pembrolizumab (an immunotherapy) after surgery helps people with triple-negative breast cancer reduce the chance of the cancer coming back, compared with close monitoring only. It’s for patients who had no remaining invasive cancer after neoadjuvant chemotherapy plus pembrolizumab.
St Louis, MissouriAges 18 years+ - NCT06827236RecruitingPhase 1/Phase 2

St Louis, MissouriAges 18 years+ - NCT03448926Recruiting
DCIS test registry to guide radiation and drug decisions
This study collects information from people with breast ductal carcinoma in situ (DCIS) to see how a specific lab test (DCISionRT) may help predict who benefits from radiation and/or certain medications. Your results and clinical details are gathered during routine care, not necessarily to change treatment right away.
St Louis, MissouriAges 30–85 - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
St Louis, MissouriAges Any age - 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.
St Louis, MissouriAges 18 years+ - NCT06465069RecruitingPhase 1
Study of an experimental drug for advanced bladder and other cancers
This trial tests a new drug called LY4052031 for people with advanced or metastatic cancers, especially bladder cancer. The drug aims to slow or stop tumor growth. Doctors will check if it is safe and how well it works.

St Louis, MissouriAges 18 years+ - NCT06179303RecruitingPhase 2
Imaging to predict response to abemaciclib for advanced breast cancer
This trial tests if a special PET scan can predict how well the drug abemaciclib works for people with advanced hormone receptor-positive, HER2-negative breast cancer. If you qualify, you would receive abemaciclib and have imaging scans to see if your cancer responds.
St Louis, MissouriAges 18 years+ - NCT06172478RecruitingPhase 2
HER3-DXd for advanced solid tumors after prior treatment
This trial tests a new targeted drug called HER3-DXd for people with several types of advanced solid tumors that have stopped responding to standard treatments.

St Louis, MissouriAges 18 years+ - NCT06910657RecruitingPhase 1
IDOV-Immune vaccine for advanced solid tumors
This trial tests an experimental virus-based treatment for people with advanced solid tumors that have stopped responding to standard therapies. The treatment is designed to infect and destroy cancer cells while boosting the immune system.
St Louis, MissouriAges 18 years+ - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.

St Louis, MissouriAges 18 years+ - NCT07391774RecruitingPhase 3
Hormone therapy with or without chemo for early breast cancer
This trial tests whether skipping chemotherapy and using only hormone therapy with a drug called ribociclib works as well as chemotherapy followed by hormone therapy with ribociclib for certain early breast cancers that have a low risk of coming back.
St Louis, MissouriAges 18 years+ - NCT06293898RecruitingPhase 1
Study of BL-M07D1 for HER2-positive solid tumors

St Louis, MissouriAges 18 years+ - NCT05929768RecruitingPhase 3
Shorter chemo plus immunotherapy without anthracyclines for early TNBC
This Phase 3 trial tests whether a shorter course of chemotherapy plus immunotherapy can work as well as standard treatment for early-stage triple-negative breast cancer. It avoids anthracycline drugs and may help reduce exposure to those medicines if the shorter plan is effective and safe.
St Louis, MissouriAges 18 years+ - NCT06440005RecruitingPhase 1
Testing AGX101 for advanced solid tumors
This study tests a new drug called AGX101 for people with advanced solid tumors that have not responded to other treatments. The goal is to see if it is safe and if it can shrink tumors or slow their growth.
