Recruiting studies
- NCT06058377RecruitingPhase 3

Study of SX-682 with atezolizumab for advanced lung cancer
This trial tests a new drug combination (SX-682 plus atezolizumab) for people with advanced non-small cell lung cancer that has grown after standard treatments like immunotherapy and chemotherapy. It aims to see if the combination can help shrink or slow the cancer.
Seattle, WashingtonAges 18 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+ - NCT07109817RecruitingPhase 2
Desloratadine to prevent nerve damage from taxane chemo in breast cancer

The Bronx, New YorkAges 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+ - NCT07102381RecruitingPhase 2
Zanidatamab plus chemo before surgery for HER2+ breast cancer
This trial tests a new drug called zanidatamab combined with chemotherapy to shrink HER2-positive breast cancer before surgery. It may help improve treatment outcomes for people with stage 2 or 3 breast cancer that has not spread.
Long Beach, CaliforniaAges 18 years+ - NCT05269381RecruitingPhase 1/Phase 2
Personalized cancer vaccine with pembrolizumab for advanced solid tumors
This trial tests a personalized vaccine made from your tumor's unique markers, combined with the drug pembrolizumab, to help your immune system fight cancer. It is for people with advanced solid tumors who have already tried standard treatments.
Jacksonville, FloridaAges 16 years+ - NCT07641985Recruiting
Fat grafting for breast reconstruction after cancer and radiation
This study compares two ways to rebuild the breast after mastectomy and radiation using your own tissue: fat grafting alone, or a more complex surgery using abdominal tissue. The goal is to see which method gives better results and quality of life.
Maastricht, LimburgAges 18 years+ - NCT07191717RecruitingPhase 2
Imlunestrant and abemaciclib for early ER+ breast cancer
This trial tests whether adding two targeted drugs, imlunestrant and abemaciclib, to your usual hormone therapy can lower the chance of your breast cancer coming back. It is for people with early-stage ER+ breast cancer who have no signs of cancer on scans but have tiny amounts of tumor DNA in their blood (called ctDNA).
Los Angeles, CaliforniaAges 18 years+ - NCT07017829RecruitingPhase 2
Combination therapy for STK11-mutant lung cancer
This trial tests a new drug (GT103) combined with the approved immunotherapy drug pembrolizumab for people with advanced lung cancer that has a specific genetic change (STK11). The goal is to see if adding GT103 helps control the cancer better than pembrolizumab alone.
Buffalo, New YorkAges 18 years+ - NCT02734537RecruitingPhase 2
Radiation with or without cisplatin after head and neck surgery
This trial studies whether adding cisplatin (a chemotherapy medicine) to radiation therapy helps people with stage III–IVA squamous cell cancer of the head and neck after they’ve had surgery. It’s meant to lower the risk of the cancer coming back.
Birmingham, AlabamaAges 18 years+ - NCT05919108RecruitingPhase 2
Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Atlanta, GeorgiaAges 18 years+ - NCT07631052RecruitingPhase 2
Low-dose Capecitabine for High-risk Early Breast Cancer
This study tests whether a low-dose chemotherapy pill called capecitabine can help prevent breast cancer from coming back in patients whose cancer shows signs of remaining disease (called MRD) despite standard treatment. The trial focuses on hormone-receptor-positive, HER2-negative breast cancers.
Toronto, OntarioAges 18 years+ - NCT06869629Recruiting
Avoiding armpit lymph node removal in breast cancer
This trial tests whether it is safe to skip removing lymph nodes from the armpit when cancer has spread there but has been found by ultrasound. If you have breast cancer that has spread to armpit lymph nodes and are not getting chemotherapy before surgery, this study may be an option.
HelsinkiAges 18 years+ - NCT07541079RecruitingPhase 3
Testing a New Breast Cancer Drug for Women Who Can't Tolerate Current Therapy
This study tests giredestrant, a new hormone-blocking medication, in postmenopausal women with early-stage ER+ breast cancer who have experienced intolerable side effects from their current aromatase inhibitor therapy. The trial will measure how well you tolerate this new drug and how it affects your quality of life.
Fountain Valley, CaliforniaAges 18 years+ - NCT07699991Recruiting
Support program for breast cancer survivors

Watching DNA in blood while taking capecitabine after breast cancer
This trial checks how a blood test that looks for cancer DNA (ctDNA) changes during and after you take capecitabine after early triple-negative breast cancer. It aims to see whether these blood test results can help monitor the chance of the cancer coming back.
Stanford, CaliforniaAges 18 years+ - NCT05304962RecruitingPhase 1
Test drug RGT-419B for advanced ER+ HER2- breast cancer
This Phase 1 study tests a new drug (RGT-419B), given alone or with hormone (endocrine) therapy, in people with advanced ER-positive, HER2-negative breast cancer that has progressed after standard treatments. It looks mainly at safety and early signs of how well the treatment may work.
La Jolla, CaliforniaAges 18 years+ - NCT05327608RecruitingPhase 2
Time-restricted eating during breast cancer chemotherapy
This study is testing whether time-restricted eating (confining all meals to a specific window each day) can improve the response to chemotherapy in women with newly diagnosed breast cancer. Participants will follow this eating pattern for 16 weeks while receiving their standard chemotherapy, and the researchers will monitor how the tumor shrinks.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06930859Recruiting
