Seoul, Jongro-guAges 19 years+ - NCT05440929Recruiting
Testing a breast-cancer prognostic tool with U.S. clinicians
This study checks how acceptable, appropriate, and easy to use a metastatic breast-cancer “prognostic calculator” is for clinicians. It may help clinicians use the tool in real practice to support care decisions for people with metastatic breast cancer.
Chapel Hill, North CarolinaAges Any age - NCT05447702RecruitingPhase 2
Testes pre-surgery treatment for triple-negative breast cancer
This trial studies giving camrelizumab plus apatinib and chemotherapy before surgery for triple-negative breast cancer. The goal is to shrink the tumor and improve outcomes by testing a combination of immune and targeted medicines along with chemotherapy.
Chengdu, SichuanAges 18–75 - NCT05449691Recruiting
Compare natural tissue samples with synthetic mesh in breast reconstruction
This study looks at how “biological” materials compare with synthetic mesh during immediate, one-stage breast reconstruction after mastectomy. It may help doctors choose the best support material to improve reconstruction outcomes for women undergoing this surgery.
DerbyAges 18 years+ - NCT05450016Recruiting
Using photos and a computer to assess breast appearance after treatment
This study uses a computer (deep neural network) to judge how the breast looks after breast-conserving surgery or full breast reconstruction and radiation therapy. It may help doctors measure cosmetic results more consistently using photographs.
Mumbai, MaharashtraAges 19–80 - NCT05451784RecruitingPhase 1/Phase 2
PD-1 TIL therapy for advanced triple-negative breast cancer
This study tests an immune-cell treatment made from your tumor tissue. It aims to help people with advanced or metastatic triple-negative breast cancer by collecting PD-1–positive immune cells and giving them back after treatment.
BarcelonaAges 18 years+ - NCT05460975Recruiting
Study of dense breast tissue seen on ultrasound
This study looks at breast cancer risk by analyzing what is seen in dense breast tissue during a screening ultrasound. It may help improve how doctors evaluate risk in people with very dense breasts.
SeoulAges 40–69 - NCT05470348RecruitingPhase 1
Test drug BL-B01D1 for advanced breast and other solid cancers
This Phase 1 trial tests BL-B01D1 in people with advanced (unresectable or metastatic) breast cancer and certain other solid tumors that have not worked with standard treatment. The goal is to learn if the drug can be given safely and to see whether it shows signs of benefit.
Guangzhou, GuangdongAges 18–75 - NCT05479409RecruitingPhase 2
Radiation before surgery for advanced breast cancer
This trial tests whether giving radiation therapy before surgery helps people with locally advanced breast cancer that hasn't been removed with chemotherapy. It may offer a new option for those who cannot have surgery right away.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05483283Recruiting
Latina women study to help access breast cancer care
This trial supports Latina women who have higher breast cancer risk and face added barriers (like cost, transportation, safety, or isolation) to get recommended breast screening and genetic risk information. It aims to help you understand your risk and access care when it’s due.
Chicago, IllinoisAges 30 years+ - NCT05491395Recruiting
Radiation after mastectomy with breast implant reconstruction
This trial studies a radiation schedule given after breast cancer surgery when your breast was rebuilt right away with a prosthesis (implant or similar). It aims to see whether this “hypofractionated” (fewer, larger treatment sessions) radiation approach is appropriate for patients who need additional (adjuvant) radiation to reduce recurrence risk.
Barretos, São PauloAges 18 years+ - NCT05490433Recruiting
Robot-assisted versus open nipple-sparing mastectomy with reconstruction
This trial compares two surgical approaches to remove the breast using a nipple-sparing mastectomy and do immediate breast reconstruction—either robot-assisted or open surgery. It aims to see how well each method works and how patients do afterward.
ChangwonAges 19–70 - NCT05490472RecruitingPhase 1/Phase 2
Study drug for advanced solid tumors that stopped responding
This early study tests a new medicine (JAB-2485) in adults with advanced solid tumors (cancers that have spread or grown locally). You may join to see if it can shrink tumors or control the disease when other treatments haven’t worked or weren’t tolerated.
Detroit, MichiganAges 18 years+ - NCT05491226RecruitingPhase 2
Pembrolizumab plus radiation and myeloid-targeting for high-risk breast cancer
This trial studies whether adding pembrolizumab (an immune “unlocking” drug) to radiation and another treatment that targets certain immune cells can improve outcomes for women with high-risk, early-stage triple negative breast cancer. You may be considered if your cancer has signs that it may respond less to immunotherapy on its own.
Los Angeles, CaliforniaAges 18 years+ - NCT05491083RecruitingPhase 1/Phase 2
Pembrolizumab plus ADG106 for advanced triple-negative breast cancer
This early-phase study tests pembrolizumab (an immune therapy) combined with ADG106 in people with advanced solid tumors, and specifically triple-negative breast cancer. It looks at whether the treatment can shrink tumors and improve outcomes for cancers that are progressing despite prior therapy.
SingaporeAges 21–99 - 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 - NCT05528133RecruitingPhase 2
Personalized radiation based on tumor genetics in triple-negative breast cancer
This trial tests whether using tumor “genetics” (information from your biopsy) to guide radiation planning can improve treatment for triple-negative breast cancer. It may help by aiming radiation more precisely while still using standard approaches where needed.
Clearwater, FloridaAges 18 years+ - NCT05535413RecruitingPhase 1/Phase 2
UTD1 plus capecitabine for HER2-negative breast cancer brain mets
This trial tests whether adding a study drug called UTD1 to capecitabine can shrink or control breast cancer that has spread to the brain. It’s for people with HER2-negative metastatic breast cancer who have brain metastases and meet specific safety and lab requirements.
ChangshaAges 18–70 - NCT05550415RecruitingPhase 2
Simvastatin with chemotherapy for triple-negative breast cancer
This trial studies whether adding simvastatin (a cholesterol medicine) can slow or change how breast cancer spreads in triple-negative breast cancer. It compares outcomes while you receive planned chemotherapy, and you may or may not be taking simvastatin as part of the study treatment.
Jakarta Pusat, DKI JakartaAges 18 years+ - NCT05557877RecruitingPhase 2
Low-dose aspirin to prevent postpartum breast cancer
This study tests whether taking a low dose of aspirin after childbirth can lower the chance of developing breast cancer later. You may be asked to provide blood, urine, and breast tissue samples so researchers can look for changes that could explain why aspirin may help.
Scottsdale, ArizonaAges 18–45 - NCT05578053Recruiting
Dalpiciclib for hormone receptor–positive advanced breast cancer
This trial studies whether dalpiciclib can slow down or control advanced hormone receptor–positive breast cancer and assess how safe it is. It’s for people whose cancer has come back in a limited way or spread and can’t be fully cured with surgery or radiation.
Shijiazhuang, HebeiAges 18 years+ - NCT05582538RecruitingPhase 2
Ceralasertib plus immunotherapy for advanced triple-negative breast cancer
This Phase 2 trial tests whether a drug called ceralasertib can help the immune system work better, followed by durvalumab plus nab-paclitaxel. It is for people with advanced triple-negative breast cancer whose cancer returned after earlier treatment, including chemotherapy and immune therapy.
Novara, NovaraAges 18 years+ - NCT05587777Recruiting
Tracking chronic conditions during standard breast cancer treatment
This study monitors health problems that can happen over time in people with breast cancer while they receive usual treatments like hormone therapy, chemotherapy, and/or radiation. It may help researchers understand which extra symptoms or complications show up and when, to improve care and follow-up.
