Capivasertib plus fulvestrant for high-risk lobular breast cancer
This trial tests adding capivasertib to fulvestrant for women with a certain type of breast cancer (invasive lobular carcinoma) that is hormone-receptor positive and has a high risk of coming back. The treatment is given before surgery to see if it works better than fulvestrant alone.
AugsburgAges 18 years+ - NCT06682793RecruitingPhase 1/Phase 2
Study of A2B395 therapy for solid tumors with EGFR and HLA loss
This trial tests a new cell therapy called A2B395 for cancers that have EGFR, a protein on the cell surface, and have lost a specific marker called HLA-A*02. The therapy uses specially engineered immune cells to target and kill these cancer cells. This may help patients with colorectal, lung, head and neck, breast, kidney, or other solid tumors that are no longer responding to standard treatments.
Gilbert, ArizonaAges 18 years+ - NCT06792552RecruitingPhase 1
Study of SIM0505 for advanced solid tumors
This trial tests a new drug called SIM0505 for people with advanced solid tumors that have not responded to standard treatments. The study looks at different cancer types, including ovarian cancer, kidney cancer, uterine cancer, and lung cancer, to see if SIM0505 can help shrink tumors or slow their growth.
Orlando, FloridaAges 18 years+ - NCT07835139Recruiting
Shorter radiation schedule after breast implant reconstruction surgery
This trial compares a shorter course of radiation (fewer, larger doses) with the standard longer course for women who have had breast cancer surgery with implant-based reconstruction. It aims to see if the shorter schedule is just as safe and effective for the chest area, while being more convenient.
ShanghaiAges 18 years+ - NCT07757763Recruiting
Slow jogging for breast cancer survivors
This study looks at whether slow jogging (a gentle form of running) can help breast cancer survivors sleep better. You'll be asked to use a smartphone app to track your activity and sleep, and you may be assigned to a jogging group or a usual-care group.
Taipei, Taipei CityAges 20 years+ - NCT06180642Recruiting
Ultrasound for arm tissue after breast cancer
This study uses ultrasound to examine arm tissue in women who have had breast cancer. It aims to see if ultrasound can reliably detect changes in arm soft tissue, which may help identify or prevent arm swelling and stiffness after treatment.
AntwerpAges 18 years+ - NCT07465393Recruiting
Facility rehab vs home exercise for breast cancer survivors
This trial compares two types of exercise programs for breast cancer survivors to see which one improves quality of life more. You will either attend supervised rehab sessions at a facility or follow a resistance exercise program at home.
New Taipei City, Xindian DistAges 18 years+ - NCT05899387Recruiting
Study fluid after breast surgery
This study looks at a problem called seroma, which is fluid buildup, after certain breast surgeries. It compares different situations where implants or tissue expanders are used, to better understand what to expect and how to manage it.
Augsburg, BavariaAges 18 years+ - NCT05494502Recruiting
Nerve block to reduce long-term pain after breast surgery
This trial tests whether a specific pain-numbing nerve block given during mastectomy can reduce chronic (long-lasting) pain after breast cancer surgery. It may help some people use less pain medicine later by lowering nerve-related pain after surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT06195709RecruitingPhase 3
Study of PET imaging and blood tests for ER+ HER2- metastatic breast cancer
This trial tests a new imaging technique (18F-FES PET/CT) along with blood markers to guide treatment for metastatic breast cancer that is ER-positive and HER2-negative. It's for people whose cancer progressed on first-line hormone therapy and who are starting a second line of hormone therapy.
BayonneAges 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.
Scottsdale, ArizonaAges 30–85 - NCT06966700RecruitingPhase 3
Study of Sac-TMT in Early High-Risk Breast Cancer
This study tests a new drug called Sacituzumab Tirumotecan (Sac-TMT) for people with early-stage, high-risk breast cancer that hasn't spread. The drug is given before surgery to see if it can shrink tumors and improve outcomes.
Gilbert, ArizonaAges 18 years+ - NCT03823144Recruiting
Imaging small live tumor details during surgery
This study uses a special camera to look at solid tumors from inside the body during an operation. It tests whether “live” tumor imaging (using a medicine called fluorescein) can be safely performed in people with certain solid cancers.
Jacksonville, FloridaAges 18 years+ - NCT05053802RecruitingPhase 2
Microwave tumor ablation plus immunotherapy for multiple lung cancers
This Phase 2 trial studies whether combining microwave ablation (a procedure to destroy lung tumors) with an immune checkpoint inhibitor can control multiple early lung cancers safely. It also aims to see how well the immune treatment helps after ablation, in people whose cancers have not spread.
Shanghai, Shanghai MunicipalityAges 18–79 - NCT06431100Recruiting
A study of TRT therapy for advanced solid tumors
This trial tests a new cell therapy called TRTs for people with advanced cancers like stomach, esophagus, cervical, breast, or lung cancer that no longer respond to standard treatments. The therapy uses your own tumor tissue or fluid to create a personalized treatment.
Zhengzhou, HenanAges 18–75 - NCT06954337Recruiting
Telehealth cancer care at home study for breast or prostate cancer
This trial tests if telehealth (video or phone visits) can be a safe and effective way to manage your cancer care at home. It is for people with breast or prostate cancer who have had at least three prior visits with their medical oncologist at Memorial Sloan Kettering.
Basking Ridge, New JerseyAges 18 years+ - NCT05003635Recruiting
Testing a vacuum device to improve breast fat reconstruction
This trial tests whether an external vacuum device (EVEBRA) can help surgeons place fat grafts more effectively during breast reconstruction. You may be able to try the device in an office visit and, if you qualify, receive reconstruction using only your own fat.
Maastricht, LimburgAges 23–69 - NCT06640881RecruitingPhase 2
Repeat breast-conserving surgery with partial reirradiation
This trial tests a new approach for women whose breast cancer has returned in the same breast after earlier surgery and radiation. Instead of removing the whole breast, doctors will remove only the tumor again and give a small, focused dose of radiation before surgery, aiming to preserve the breast.
AmsterdamAges 50 years+ - NCT04349527Recruiting
Comparing breast-conserving surgeries and how you feel after
This trial compares two breast-conserving surgery techniques to see how they affect cosmetic results (how the breast looks), quality of life, and patient satisfaction. It may help guide the best surgical approach for people eligible for breast conservation.
