Recruiting studies
- NCT07012720Recruiting
Comparing breast cancer treatments before surgery
This trial looks at different drug combinations given before surgery to shrink breast tumors. The goal is to find which treatments work best for different types of breast cancer, such as triple-negative, HER2-positive, or hormone-receptor-positive. If you are a woman scheduled for neoadjuvant therapy (treatment before surgery) and have not had previous cancer treatment, this study may be for you.
Xi'an, ShaanxiAges 25–75 - NCT07003074RecruitingPhase 3
New drug TQB2102 vs standard therapy for HER2+ breast cancer
This trial tests a new medicine called TQB2102 against the standard combination of chemotherapy (docetaxel) plus two targeted therapies (trastuzumab and pertuzumab) for people with HER2-positive breast cancer that has come back or spread. The goal is to see if the new treatment works better and has fewer side effects.
Hefei, AnhuiAges 18–75 - NCT07002177RecruitingPhase 1/Phase 2
Combination therapy study for ER+/HER2- breast cancer
This trial tests a new drug called FWD1802 combined with other treatments for people with a certain type of advanced breast cancer (ER-positive, HER2-negative). It aims to find better options if standard treatments have stopped working or aren't suitable.
ShanghaiAges 18–75 - NCT06993714RecruitingPhase 2
3D-printed absorbable breast implants for reconstruction
This trial tests a new type of breast implant made from a special material that your body can safely absorb over time. It is designed for women who need breast reconstruction after breast cancer surgery, aiming to restore shape without leaving a permanent implant.

New technique for nipple-sparing mastectomy with immediate implant reconstruction
This trial tests a special tool (HUAXI Hole 1) for a type of breast cancer surgery that removes breast tissue while saving the nipple, followed by placing an implant right away. It may be an option for women with early-stage breast cancer or those who choose preventive mastectomy.
Fuzhou, FujianAges 18–70 - NCT06967103RecruitingPhase 2
New drug before breast cancer surgery
This trial tests a new drug, QL1706, given alongside chemotherapy before surgery for a certain type of breast cancer. It aims to see if this combination helps shrink tumors before they are removed.
ZhengzhouAges 18 years+ - 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 - NCT06966050Recruiting
Blood test registry for inflammatory breast cancer
This study collects blood samples from people with inflammatory breast cancer (IBC) to learn more about the disease. It uses a special blood test called Signatera to look for cancer DNA, and the information is stored in a registry for research.
Houston, TexasAges 18 years+ - NCT06958328RecruitingPhase 3
Higher dose radiation for locally advanced pancreatic cancer
This trial tests whether giving a higher dose of radiation to the pancreas is safe and effective for people with locally advanced pancreatic cancer who have already had chemotherapy without progression.
Gilbert, ArizonaAges 18 years+ - NCT06961955RecruitingPhase 2
Shorter versus longer whole breast radiation for early-stage breast cancer
This trial compares a 5-day course of whole breast radiation plus a boost to the standard 9-day course for people with early-stage breast cancer who have certain risk factors, such as high-grade tumors or younger age. The goal is to see if the shorter treatment is just as safe and effective.
Salt Lake City, UtahAges 18 years+ - NCT06954831RecruitingPhase 2
Short-course radiation for early-stage breast cancer
This trial tests a shorter, more intense radiation schedule for people with stage I-III breast cancer after lumpectomy. It aims to find if giving a higher daily dose over fewer sessions is safe and effective.
Arcadia, CaliforniaAges 40 years+ - 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+ - NCT06949410RecruitingPhase 1
HER2 vaccine study for high-risk breast cancer
This trial tests a vaccine designed to help the immune system fight remaining HER2-positive breast cancer cells after standard treatment. It is for people who have completed at least six months of HER2-targeted therapy and still have a high risk of the cancer coming back.
Indianapolis, IndianaAges 18 years+ - NCT06938555Recruiting
Can extending nightly fasting improve sleep and thinking in breast cancer survivors?
This study tests whether eating all your meals within a shorter window each day (prolonged nightly fasting) can help improve sleep and thinking skills in breast cancer survivors who have memory or concentration problems.
Phoenix, ArizonaAges 18 years+ - NCT06927180RecruitingPhase 2
Study of SHR-A1811 plus pertuzumab before surgery for HER2+ breast cancer
This trial tests a combination of two targeted drugs (SHR-A1811 and pertuzumab) given before surgery to shrink HER2-positive breast cancer. It aims to see if this approach improves outcomes for patients with early-stage but high-risk disease.
Zhengzhou, HenanAges 18–70 - NCT06924788Enrolling by invitation

Radiation and immunotherapy before surgery for HR+/HER2- breast cancer
This trial is testing a new treatment approach for patients with a certain type of breast cancer (HR+/HER2-). It combines radiation therapy with chemotherapy and an immunotherapy drug before the patient's main surgery, to see if it can shrink or eliminate the tumor more effectively.

Chemo plus immunotherapy for early HR+/HER2- breast cancer
This trial tests adding an immunotherapy drug (serplulimab) to standard chemotherapy for early-stage HR+/HER2- breast cancer. The goal is to see if the combination works better than chemo alone before surgery.
