It’s for patients who had no remaining invasive cancer after neoadjuvant chemotherapy plus pembrolizumab.
Los Angeles, CaliforniaAges 18 years+ - NCT05827081RecruitingPhase 3
Ribociclib plus endocrine therapy for early breast cancer
This trial studies whether adding ribociclib to standard hormone (endocrine) therapy lowers the risk of breast cancer coming back in early-stage, hormone-receptor–positive cancer. It mainly looks at safety and how well the treatment controls cancer after surgery and (sometimes) prior hormone treatment.
Los Angeles, CaliforniaAges 18–100 - NCT06092892RecruitingPhase 2
Upfront targeted lymph node removal for early breast cancer

Los Angeles, CaliforniaAges 18 years+ - NCT06764940RecruitingPhase 2
Utidelone and capecitabine for HER2-negative breast cancer with brain metastases
This trial tests if the combination of Utidelone and capecitabine can shrink brain metastases in people with HER2-negative breast cancer. It is designed for those whose cancer has spread to the brain and who have not had many prior treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT07524322RecruitingPhase 1
RGT-490 for Advanced Cancers With PIK3CA Mutations
This study tests a new drug called RGT-490 in patients with advanced solid tumors (cancers that have spread or cannot be removed by surgery) that have a specific genetic change called a PIK3CA mutation. The drug is designed to block a protein involved in cancer cell growth.
Los Angeles, CaliforniaAges 18 years+ - NCT07629206Recruiting
Freezing therapy for small, early-stage breast cancer
This study tests whether freezing a small breast tumor (cryoablation) is a safe and effective treatment option for older adults with early-stage, hormone-receptor-positive breast cancer. Instead of surgery, the goal is to destroy the tumor by freezing it in place.
Glendale, CaliforniaAges 70 years+ - NCT05372614RecruitingPhase 1
Testing trastuzumab deruxtecan and neratinib for HER2-positive cancers
This trial tests a combination of two targeted drugs, trastuzumab deruxtecan (Enhertu) and neratinib, for people with solid tumors that have a HER2 gene change. The goal is to see if the combination is safe and works well for cancers that have not responded to at least one prior treatment.
South Pasadena, CaliforniaAges 18 years+ - NCT04305834RecruitingPhase 2
Abemaciclib plus hormone pills for metastatic breast cancer in older adults
This Phase 2 study tests whether abemaciclib combined with standard hormone (endocrine) therapy can better control metastatic breast cancer in people age 70 and older. It may help if your cancer has already grown despite prior hormone therapy and/or other cancer medicines.
South Pasadena, CaliforniaAges 70 years+ - NCT04722341Recruiting
Time-limited eating for people with certain breast or rectal cancers
This study tests whether eating only within a shorter daily time window can improve cancer outcomes in people with specific breast or rectal cancers. It also looks at how this affects the body (such as metabolism) and who is most likely to benefit.
West Hollywood, CaliforniaAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
