Recruiting studies
- NCT05736367Recruiting
Study tumor metabolism in certain types of breast cancer surgery
This study looks at how breast cancer cells use energy and nutrients in hormone-receptor positive, HER2-negative tumors during planned surgery. It may help researchers understand the cancer better by comparing tumor tissue with nearby normal tissue.
New Brunswick, New JerseyAges 18 years+ - NCT05748834RecruitingPhase 2
Tucatinib plus Doxil for HER2-positive metastatic breast cancer
This Phase 2 study tests tucatinib (a HER2-targeted pill) plus Doxil (a chemotherapy medicine) to slow or shrink HER2-positive metastatic breast cancer that has been treated before. It may help by targeting HER2 cancer cells more effectively than past treatments alone.
Columbia, MarylandAges 18 years+ - NCT05760612RecruitingPhase 3
After breast cancer surgery, test neratinib plus trastuzumab
This trial studies whether adding neratinib to standard trastuzumab treatment after neoadjuvant (before-surgery) therapy lowers the risk of breast cancer coming back. It is for people whose breast cancer is hormone-receptor positive and HER2 positive, with residual cancer found after neoadjuvant treatment.
GuangzhouAges 18–70 - NCT05769010RecruitingPhase 2
HER2-positive or low breast cancer brain metastasis drug study
This Phase 2 study tests SHR-A1811 in people with HER2-positive (or HER2-low) advanced breast cancer that has spread to the brain. It aims to shrink brain tumors and control the cancer in the brain, especially when there was no need for urgent local treatment like radiation or surgery.
Zhengzhou, HenanAges 18–75 - NCT05795101RecruitingPhase 2
TRUDI trial for inflammatory breast cancer with HER2/low markers
This Phase 2 trial tests two medicines—durvalumab and trastuzumab deruxtecan—to treat stage III inflammatory breast cancer. It may help by controlling cancer growth using treatments aimed at specific breast cancer markers (HER2 positive or “HER2-low”).
Boston, MassachusettsAges 18 years+ - NCT05816655RecruitingPhase 2
Test two hormone treatment combinations for metastatic breast cancer
This Phase 2 study compares two combinations of hormone-blocking drugs plus an anti-cancer targeted pill to see which works better for hormone-receptor positive, HER2-negative metastatic breast cancer. It may help by finding a more effective treatment plan when the cancer has spread.
SeoulAges 19–80 - NCT05824975RecruitingPhase 1/Phase 2
Test drug GI-102 alone or with cancer medicines
This Phase 1/2 study tests whether GI-102 is safe and can help shrink advanced solid tumors. It also looks at GI-102 used with standard cancer treatments like pembrolizumab or trastuzumab deruxtecan (T-DXd).
Scottsdale, ArizonaAges 18 years+ - NCT05837455RecruitingPhase 2
Biomarker-guided treatment for early breast cancer before surgery
This trial looks at whether using tumor test results (biomarkers) can help guide the best hormone treatment and chemotherapy before surgery. It focuses on people with stage II or III, ER-positive, HER2-negative breast cancer, with the goal of improving how well the tumor responds before it is removed.
St Louis, MissouriAges 18 years+ - NCT05838066RecruitingPhase 3
KN026 plus HB1801 for HER2-positive advanced breast cancer
This Phase 3 study tests whether taking KN026 with HB1801 as first treatment works better and is safe for people with HER2-positive breast cancer that has come back or spread. It may help by improving tumor response and delaying progression compared with the study’s treatment plan.
Beijing, chaoyangAges 18 years+ - NCT05846789RecruitingPhase 2
Chemotherapy with or without tocilizumab for breast cancer
This Phase 2 trial tests whether adding tocilizumab (a drug that targets inflammation signals) to standard chemotherapy helps people with triple-negative or ER-low metastatic or locally recurring breast cancer. It’s for adults who have had up to two prior treatments for metastatic disease and who can receive standard chemo.
Atlanta, GeorgiaAges 18 years+ - NCT05851014RecruitingPhase 3
GB491 plus letrozole for HR+ HER2- advanced breast cancer
This Phase 3 study tests whether GB491 used together with letrozole works better for hormone receptor–positive and HER2-negative advanced breast cancer. You may be eligible if you have not had certain prior cancer treatments and your health tests are within safe limits.
Bengbu, AnhuiAges 18–75 - NCT05858398Recruiting
How body composition affects chemotherapy results in breast cancer
This study looks at whether body fat and muscle (body composition) change how well certain chemotherapy works after surgery for early breast cancer. You may be considered if you are planned to receive docetaxel as adjuvant (after-surgery) chemotherapy and have recent CT scan images.
RouenAges 18 years+ - NCT05861271RecruitingPhase 2
Adjuvant pyrotinib plus capecitabine for tiny HER2 breast cancer
This trial studies whether adding pyrotinib and capecitabine after surgery can lower the risk of cancer coming back in people with very small, lymph-node–negative, HER2-positive breast cancer. It’s for patients who fit specific tumor size and HER2 test results and who can safely take chemotherapy-like medicines and stay on contraception during treatment.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05867251RecruitingPhase 1/Phase 2
AVZO-021 for advanced breast and ovarian cancers
This early-stage study tests AVZO-021, a new anti-cancer medicine, in people with advanced solid tumors like specific types of breast and ovarian (or related) cancers. It’s meant to find the safest dose and look for signs the medicine can shrink tumors, especially in cancers with certain gene changes.
New Haven, ConnecticutAges 18 years+ - NCT05868226RecruitingPhase 1
Early cancer drug study for adults with advanced tumors
This Phase 1 study tests early (first-in-program) cancer medicines in people whose cancer has not been adequately controlled. It helps researchers learn the safest dose and early signs of whether the treatment may work for different tumor types and treatments.
Birmingham, AlabamaAges 18 years+ - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT05877859Recruiting
Testing pembrolizumab with chemo before breast cancer surgery
This trial studies whether adding pembrolizumab (an immunotherapy) to standard chemotherapy before surgery improves immune and clinical responses in people with early-stage triple-negative breast cancer. You may benefit by getting a potentially more effective treatment plan, while the study team closely monitors your response.
Atlanta, GeorgiaAges 18 years+ - NCT05891561RecruitingPhase 2
Short antibody treatment after surgery for early HER2+ breast cancer
This Phase 2 study tests a shorter schedule of trastuzumab and pertuzumab combined with chemotherapy (taxanes) to reduce breast cancer coming back after surgery. It mainly helps people with early-stage, HER2-positive breast cancer that has not spread, by testing whether a shorter plan still works well and is tolerable.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05894239RecruitingPhase 3
Tested targeted drug for HER2-positive breast cancer with PIK3CA changes
This Phase 3 study tests inavolisib plus Phesgo versus placebo plus Phesgo in people whose breast cancer has both HER2-positive and PIK3CA-mutated tumor markers. The goal is to see if adding inavolisib improves how well the treatment controls the cancer and how safe it is.
Gilbert, ArizonaAges 18 years+ - NCT05900206RecruitingPhase 2
Trastuzumab deruxtecan vs standard chemotherapy before breast surgery
