Recruiting studies
- NCT07029399RecruitingPhase 1
Study of NKT5097 for advanced solid tumors
This trial tests an experimental oral drug (NKT5097) for people with advanced solid tumors that have not responded to other treatments. It may also be an option for people with a specific type of breast cancer (HR+/HER2-). The goal is to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07030569Recruiting
Predicting treatment response in metastatic breast cancer
This trial studies how well CT and PET scans can predict if a certain type of breast cancer will respond to a targeted treatment. It focuses on women who had a biopsy of the liver, lung, or chest lining after the cancer spread.
MilanAges Any age - NCT07037576Recruiting
Breast reconstruction study for patients needing radiation after mastectomy
This study compares two types of breast reconstruction for women who need radiation therapy after their mastectomy: one-stage reconstruction using a permanent implant placed in front of the chest muscle, versus the standard two-stage approach where a tissue expander is used first and replaced with a permanent implant later. The goal is to see which method works better and is safer for patients who require post-mastectomy radiation.
Henan, HenanAges 18–70 - NCT07040891Recruiting
Testing a program to boost breast cancer trial talks
This study is testing a program called 'Just ASK' that helps cancer care teams talk to patients about clinical trials. The researchers want to see if the program increases how often patients discuss and consider joining a breast cancer trial.
Plainsboro, New JerseyAges 18 years+ - NCT07042581RecruitingPhase 4
Revaree Plus for vaginal dryness in breast cancer survivors
This trial tests a vaginal insert called Revaree Plus to see if it helps breast cancer survivors who have vaginal dryness or pain from hormone therapy. It may be a good option if you are on an aromatase inhibitor or tamoxifen and have discomfort.
Basking Ridge, New JerseyAges 18 years+ - NCT07044310RecruitingPhase 2
Probiotics for preventing bone loss during breast cancer hormone therapy
This trial tests if a probiotic supplement can help prevent bone loss in women with HR-positive breast cancer who are starting an aromatase inhibitor. You would take the probiotic daily and provide blood and stool samples to see how it affects your bone health.
Jacksonville, FloridaAges 18 years+ - NCT07053085RecruitingPhase 2
Surgery or radiation for stable HER2+ breast cancer spread
This study tests whether combining surgery or strong focused radiation with standard treatment can help people whose HER2-positive breast cancer has spread to a few spots (5 or fewer) in the body, but not the brain. It's for patients whose cancer is stable after at least 3 months of first-line therapy.
Basking Ridge, New JerseyAges 18 years+ - NCT07054190RecruitingPhase 2
Testing Inavolisib in early-stage breast cancer with PIK3CA mutation
This trial is testing a drug called Inavolisib (a type of targeted therapy) given before surgery for people with early-stage, hormone receptor-positive, HER2-negative breast cancer that has a specific genetic change (PIK3CA mutation). The goal is to see if adding Inavolisib to standard endocrine therapy can shrink the tumor more effectively.
Los Angeles, CaliforniaAges 18 years+ - NCT07057427RecruitingPhase 3
Nab-paclitaxel vs TCbHP for HER2-positive early breast cancer
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 - NCT07070791Recruiting
Exercise program for arm strength and fitness after breast cancer
This trial tests whether a combination of arm-strengthening and aerobic exercises helps breast cancer patients who are at least 15 months past surgery and not very active. The goal is to see if this home-based program improves arm function and overall fitness.
Ankara, StateAges 18–80 - NCT07071038RecruitingPhase 2
Switching medication to relieve side effects from aromatase inhibitors
This trial tests whether switching to a different aromatase inhibitor or using standard treatments works better for managing side effects in breast cancer survivors. It aims to help you stay on hormone therapy longer with fewer discomforts.
Lebanon, New HampshireAges 18 years+ - NCT07071272Recruiting
Comparing two breast imaging methods before surgery
This trial compares a special mammogram with dye (CEDM) to MRI for women already diagnosed with invasive breast cancer. The goal is to see if CEDM works as well as MRI for planning surgery, potentially offering a faster or easier option.
Verona, ItalyAges 30 years+ - NCT07071402Recruiting
Ultrasound-guided vacuum removal plus surgery for early small breast cancer
This trial tests a less invasive approach for early breast cancer. First, doctors use ultrasound to guide a vacuum device to remove the small tumor (≤2 cm). Then surgery is done. The goal is to see if this combined method works well and is safe for women with early-stage breast cancer.
Xi'an, ShaanxiAges 18–70 - NCT07073755Recruiting
Study of next treatments after targeted therapy resistance for advanced breast cancer
This study looks at what happens when people with advanced breast cancer switch to a new treatment after their cancer becomes resistant to targeted therapies like CDK4/6 inhibitors, PIK3CA inhibitors, or T-DXd. Researchers want to understand which next treatments work best in real life.
Changsha, HunanAges 18 years+ - NCT07076485RecruitingPhase 2
Shorter radiation after surgery for node-positive breast cancer
This trial tests shorter radiation schedules for people with breast cancer that has spread to lymph nodes or is high-risk. It aims to find a shorter course of radiation that is just as effective after surgery.
Loveland, ColoradoAges 18 years+ - NCT07080476Recruiting
Kinesio taping for chronic swelling after breast cancer
This trial tests whether Kinesio taping, a special type of elastic tape, can reduce long-term swelling in the breast or upper body (trunk) after breast cancer treatment. If you have had breast cancer and still have swelling lasting more than six months, this study may help find a new way to manage that swelling.
AntwerpAges 18 years+ - NCT07081555RecruitingPhase 1
Testing a new radioactive drug for HER2-positive advanced breast cancer
This trial tests a new radioactive drug, [177Lu]Lu-ABY-271, to see how safe it is and where it goes in the body. It is for people with HER2-positive breast cancer that has spread and cannot be removed by surgery.
GothenburgAges 18 years+ - NCT07084571Recruiting
Testing Tissue Sampling Over Time in Advanced Breast Cancer
This study is testing whether it is safe and practical to take multiple small tissue samples (biopsies) from different sites of your breast cancer over time. The goal is to learn how breast cancer changes as it grows, which could help doctors develop better treatments.
LondonAges 18 years+ - NCT07095023Recruiting
Oral chemo and targeted therapy before breast cancer surgery
This trial tests a combination of an oral chemotherapy pill (paclitaxel) with two targeted antibodies (pertuzumab and trastuzumab) given before surgery for HER2-positive breast cancer. The goal is to shrink the tumor and make surgery more effective.
Beijing, Beijing MunicipalityAges 18–75 - NCT07095114Recruiting
Disappearing markers for daily breast radiation
This study tests whether small disappearing ink marks can be used to guide daily radiation treatments for breast cancer. It may help make radiation more precise and comfortable.
Detroit, MichiganAges 18 years+ - NCT07096180Recruiting

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,472 recruiting breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
