This study looks at how your immune system reacts to anti-HER2 treatments in people with HER2-positive breast cancer. It may help doctors understand who responds best by studying immune signals in blood (and sometimes tissue) during or after treatment.
Jacksonville, FloridaAges 18 years+ - NCT04589468Recruiting
Exercise for cancer survivors at high risk
This study tests whether a structured exercise program can help prevent cancer from coming back in people who have been treated for certain solid tumors (colorectal, ovarian, lung, or breast cancer). If you've completed surgery and adjuvant therapy within the past 2 years and are currently not exercising much, you may be eligible. Participation involves following an exercise plan and regular check-ins.
Durate, CaliforniaAges 18 years+ - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04267848RecruitingPhase 3
Testing immunotherapy with chemo after lung cancer surgery
This trial tests whether adding an immunotherapy medicine to standard chemotherapy after surgery can improve outcomes for some people with non-small cell lung cancer. It may help by boosting the immune system to reduce the chance the cancer comes back.
Anchorage, AlaskaAges 18 years+ - NCT04333537RecruitingPhase 2/Phase 3
Sentinel node biopsy versus standard neck surgery for early mouth cancer
This trial compares two ways of checking whether early oral cavity squamous cell cancer has spread to neck lymph nodes. It tests whether sentinel lymph node biopsy can find spread as well as standard neck dissection, while potentially reducing more extensive surgery for some people.
Birmingham, AlabamaAges 18 years+ - NCT04329065RecruitingPhase 2
Vaccine with targeted breast cancer drugs before surgery
This Phase 2 trial tests whether adding a cancer vaccine (with GM-CSF) to standard HER2-targeted chemotherapy before surgery improves treatment outcomes for HER2-positive breast cancer. If you join, you’ll receive planned medicine before surgery to treat the tumor, then continue with the study schedule.
Seattle, WashingtonAges 18 years+ - NCT04005690RecruitingEarly Phase 1
Targeted drug treatment for pancreatic cancer using pathway changes
This early-phase trial tests how well targeted medicines (and possibly an immunotherapy drug) work for people with pancreatic cancer that can’t be fully removed with surgery or has spread. It also looks at whether the treatment is safe and can shrink or control tumors by blocking specific cancer pathways.
Portland, OregonAges 18 years+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Gilbert, ArizonaAges 30 years+ - NCT02918474Recruiting
Decision tool for mastectomy choices in new breast cancer
This study tests a decision-making tool to help people with newly diagnosed breast cancer make choices about removing the other (opposite) breast as a preventive step. It may help you think through risks and options in a clearer, more structured way.
Houston, TexasAges 18 years+ - NCT02732860Recruiting
Test your tumor’s drug response using a lab model
This trial grows a lab model from your own tumor tissue (or resected tissue) to predict which drugs might work best. It’s meant to match investigational treatments to your specific tumor biology.
Toronto, OntarioAges 18 years+ - NCT02772367Recruiting
Make heart muscle cells from blood or skin in breast cancer
This study grows heart muscle cells from your blood or skin to better understand why some people develop heart problems from HER2 cancer treatments. You may be helping researchers learn how to predict and prevent treatment-related heart damage.
New York, New YorkAges 18 years+ - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Birmingham, AlabamaAges 18 years+ - NCT07743190RecruitingPhase 2
Lighter chemo for early-stage triple-negative breast cancer with high immune cells
This trial tests a less intense chemotherapy regimen (without one of the standard drugs) combined with immunotherapy for people with early-stage triple-negative breast cancer whose tumors have a high level of immune cells (TILs). The goal is to see if this approach is effective while reducing side effects.
Syracuse, New YorkAges 18 years+ - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT07655934Recruiting
Lifestyle and energy in breast cancer survivors
This study looks at how lifestyle and energy levels affect women recently diagnosed with early-stage breast cancer. It may help researchers understand the body's changes during treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06636981RecruitingPhase 2
Combination therapy for advanced triple negative breast cancer
This trial tests a new combination of a vitamin A derivative (all-trans retinoic acid), an immunotherapy drug (toripalimab), and chemotherapy for people with advanced triple negative breast cancer that cannot be removed by surgery or has spread. The goal is to see if this combination helps shrink or control the cancer better than current treatments.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07393425RecruitingPhase 2
Study of two targeted therapies before surgery for HER2+ breast cancer
This trial tests a combination of two drugs, trastuzumab deruxtecan (SHR-A1811) and pertuzumab, given before surgery to shrink HER2-positive breast cancer. It is for women with stage II or III breast cancer who have not yet had treatment and are in good overall health.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06811870RecruitingPhase 1/Phase 2
Hyperbaric oxygen before surgery for breast cancer
This trial tests adding hyperbaric oxygen (breathing pure oxygen in a pressurized chamber) before standard chemotherapy for breast cancer. The goal is to see if it helps shrink the tumor more effectively before surgery.
Guangzhou, GuangdongAges 18–60 - NCT07162298RecruitingPhase 2
Dragon boat racing vs. home exercise for breast cancer patients
This study compares dragon boat racing with unsupervised home exercise to see which better improves physical function and quality of life in breast cancer patients. It may help you become more active and feel better during recovery.
