This trial compares two different drug combinations given before surgery to shrink HER2-positive breast cancer tumors. The goal is to see which combination works better and has fewer side effects.
Zhengzhou, HenanAges 18–70 - NCT07007169RecruitingPhase 2
Mediterranean diet study for early breast cancer
This trial tests whether eating a Mediterranean-style diet (rich in vegetables, fruits, whole grains, and healthy fats) can help improve outcomes for women with early breast cancer who are receiving chemotherapy. You will be asked to follow this diet and keep a food diary using an online tool.
Sønderborg, Southern DenmarkAges 18 years+ - NCT06992882RecruitingPhase 3
Comparing two chemo regimens with Herceptin for early breast cancer
This trial tests if taking oral chemotherapy pills with trastuzumab (Herceptin) works as well as IV chemo (paclitaxel) with Herceptin after surgery for HER2-positive, lymph node-negative early breast cancer. It aims to find a more convenient treatment option.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06970912RecruitingPhase 2
ctDNA-Guided Reduced Chemo in HR+/HER2- Breast Cancer
This study is testing whether using a ctDNA blood test can help doctors decide if patients with hormone receptor-positive, HER2-negative breast cancer can safely receive less intensive chemotherapy after surgery. The goal is to reduce side effects while still preventing the cancer from coming back.
Beijing, Beijing MunicipalityAges 18–75 - NCT06946238Recruiting
Single-dose radiation after surgery for low-risk breast cancer
This trial tests giving a single, very targeted dose of radiation right after surgery for early-stage breast cancer. It is for women age 40+ with small, low-risk tumors (Luminal A or B) that have been fully removed and have not spread to lymph nodes.
MilanAges 40 years+ - NCT06917313RecruitingPhase 2
Fezolinetant for hot flashes in women with breast cancer on hormone therapy
This trial tests a drug called fezolinetant to see if it reduces hot flashes in women with HR+ breast cancer who are on hormone therapy (like tamoxifen or aromatase inhibitors). You need to be postmenopausal and having at least 7 moderate to severe hot flashes a day.
New Haven, ConnecticutAges 18 years+ - NCT06518837RecruitingPhase 2
Tirzepatide for weight loss in early breast cancer
This study tests if tirzepatide (a weight loss drug) can help women and men with early-stage hormone receptor-positive breast cancer who are overweight or obese. The goal is to see if losing weight can improve outcomes after completing their initial breast cancer treatment.
