Breast cancer study: linking metabolism to tumor behavior
This study looks at how your metabolism (things like blood sugar and cholesterol) might be linked to tumor genes and growth in people with breast cancer. The goal is to find new ways to treat the disease based on your metabolic profile. You may be eligible if you have locally advanced breast cancer (Stage II–III) and are willing to share your medical records.
RomaAges 18 years+ - NCT06817525RecruitingPhase 2
Chemo and immunotherapy before surgery for early triple-negative breast cancer
This trial tests whether a combination of chemotherapy drugs (nab-paclitaxel and carboplatin) plus an immunotherapy drug (PD1 inhibitor) given before surgery can help treat early-stage triple-negative breast cancer. It aims to improve outcomes by using these treatments before the main surgery.
Zhengzhou, HenanAges 18–65 - NCT05708235RecruitingPhase 2
Blood test monitoring for early breast cancer recurrence
This trial uses a blood test to look for tiny bits of tumor DNA after treatment. If found, participants receive new drug combinations to try to prevent cancer from returning.
A CoruñaAges 18 years+ - NCT07222267RecruitingPhase 1
Study of BG-75202 for advanced solid tumors
This trial tests a new drug called BG-75202, alone or with other drugs, for people with advanced breast cancer or other solid tumors that have stopped responding to standard treatments. It may offer a new option when other treatments have failed.
Birmingham, AlabamaAges 18 years+ - NCT05232916RecruitingPhase 3
Vaccine for HER2-positive breast cancer after standard treatment
This trial tests a vaccine (GLSI-100) that may help prevent the return of HER2-positive breast cancer. It is given to patients who still had cancer cells after initial treatment with trastuzumab, or who had stage III disease and achieved a complete response.
Mobile, AlabamaAges 18–100 - NCT06722599Recruiting
Shorter chemo with targeted drugs for low-risk HER2 breast cancer
This trial tests whether a short course of chemo plus two targeted drugs (trastuzumab and pertuzumab) before surgery works well for people with early-stage, low-risk HER2-positive breast cancer. It may help reduce the need for stronger chemo later.
Beijing, Beijing MunicipalityAges Any age - NCT06923527RecruitingPhase 2
Testing ctDNA to start elacestrant in early breast cancer
This trial tests whether the drug elacestrant can help prevent recurrence in people with a type of breast cancer (ER+/HER2-) who have finished hormone therapy and have signs of cancer DNA in their blood (ctDNA positive) but no visible spread on scans.
New Haven, ConnecticutAges 18 years+ - NCT06607757RecruitingPhase 2
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+ - NCT07311083Recruiting
Lifestyle program for triple-negative breast cancer patients
This study tests a lifestyle program (diet, exercise, and support) for women with triple-negative breast cancer who are getting chemotherapy plus immunotherapy before surgery. The goal is to see if healthy habits can help during treatment.
Essen, North Rhine-WestphaliaAges 18–75 - NCT05525767RecruitingPhase 4
Bevacizumab plus chemo before surgery for HER2-negative breast cancer
This trial studies whether adding bevacizumab (an anti-blood-vessel medicine) to chemotherapy before surgery improves treatment outcomes for people with HER2-negative breast cancer. It’s mainly for tumors that are stage II to IIIC and have not had prior cancer treatment.
