All recruiting trials (16)
-
Oral paclitaxel with anti-HER2 therapy in HER2-positive breast cancer before surgery
This trial tests a paclitaxel oral solution given with trastuzumab and pertuzumab to see if a safe dose can be found for women with HER2-positive breast cancer before they have surgery.
-
Olaparib with Trastuzumab and Pertuzumab before surgery for older women with HER2-positive breast cancer
This trial tests whether adding olaparib to standard HER2-targeted therapy can help older women with newly diagnosed, operable HER2-positive breast cancer before surgery.
-
Pyrotinib-based regimens for advanced HER2-positive breast cancer: real-world sequential therapy after progression
This real-world study tests whether giving disitamab vedotin after pyrotinib-based treatment helps people with advanced HER2-positive breast cancer.
-
Pre-surgery trastuzumab deruxtecan (SHR-A1811) plus pertuzumab for HER2-positive breast cancer
This trial tests giving trastuzumab deruxtecan (SHR-A1811) with pertuzumab before surgery to see if it helps women with stage II–III HER2-positive breast cancer achieve a complete response.
-
HLX22 plus HLX87 as first-line treatment for HER2-positive recurrent or metastatic breast cancer
This will test whether combining HLX22 with HLX87 helps adults with HER2-positive recurrent or metastatic breast cancer when given as a first-line treatment.
-
Capecitabine with or without elacestrant for ER-positive advanced breast cancer
This trial will try adding elacestrant to capecitabine to see if it helps people with ER-positive, HER2-negative advanced breast cancer that stopped responding to CDK4/6 inhibitors.
-
Using blood-based tumor DNA (ctDNA) to find leftover breast cancer after treatment
This research will test whether a simple blood test that looks for tiny bits of tumor DNA can tell if people treated for breast cancer (including HR+/HER2-, HER2+, and triple-negative) still have leftover cancer or are at risk of recurrence.
-
First human use of [177Lu]Lu-ABY-271 to target HER2-positive metastatic breast cancer
This first-in-human Phase 1 test will see if the radiopharmaceutical [177Lu]Lu-ABY-271 is safe and how it distributes in the body for people with HER2-positive metastatic breast cancer.
-
RC48 with bevacizumab or pyrotinib for HER2-positive metastatic breast cancer after T-Dxd failure
This trial will try RC48 together with either bevacizumab or pyrotinib in adults with HER2-positive metastatic breast cancer whose disease has progressed after trastuzumab deruxtecan (T-Dxd).
-
Radiology-based prediction of HER2 level and T‑DXd benefit in metastatic breast cancer
This study tests whether patterns in CT or FDG‑PET images can show HER2 level and help predict response to trastuzumab deruxtecan for people with metastatic breast cancer.
-
Understanding breast cancer response during pre-surgery treatment
This study is trying to see how breast cancer responds to treatment before surgery by looking at tissue and blood samples from patients to find out what factors might affect their recovery and risk of cancer coming back.
-
Registry for HER2-positive breast cancer patients
This study is collecting information from people with HER2-positive breast cancer to see how different factors affect their treatment outcomes and overall care.
-
Evaluating IAM1363 for HER2-related cancers
This study is testing a new treatment called IAM1363 to see if it can help people with advanced cancers that have changes in the HER2 gene.
-
Adding targeted radiation therapy to drug treatment for breast cancer
This study is testing whether adding targeted radiation therapy to regular drug treatment can help people with a specific type of breast cancer keep their disease from getting worse or spreading.
-
Evaluating PC14586 for advanced solid tumors with a specific mutation
This study is testing a new oral medication called PC14586 to see if it can help people with advanced solid tumors that have a specific mutation in the TP53 gene.
-
Evaluating PC14586 for advanced solid tumors with a specific mutation
This study is testing a new oral medication called PC14586 to see if it can help people with advanced solid tumors that have a specific mutation in the TP53 gene.
NIH-funded research (3)
Early-stage science funded by the US National Institutes of Health. Most of these projects don't enroll patients, but they show what is being worked on.
-
BRD8's role in hormone-receptor positive, HER2-positive breast cancer
This project looks at whether targeting a protein called BRD8 can help people with hormone-receptor positive, HER2-positive breast cancer respond better to HER2 treatments.
-
Understanding how BRD8 affects hormone receptor-positive and HER2-positive breast cancer
This study is looking into how a protein called BRD8 affects breast cancer that is both hormone receptor-positive and HER2-positive, to find out why some patients don’t respond well to current treatments and to discover new ways to help them feel better.
-
Targeting lipid metabolism to improve treatment for HER2+ breast cancer that has spread to the brain
This study is looking at how to make treatments work better for people with HER2 positive breast cancer that has spread to the brain by finding ways to block the cancer cells' use of fats to grow, which could help existing therapies be more effective.
