New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
San Antonio, TexasAges 18 years+ - NCT06492616RecruitingPhase 3
Elacestrant vs standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy pill (elacestrant) against standard hormone therapy for people with a common type of early breast cancer (ER+, HER2-) that has a higher chance of returning. You may qualify if you've already been on hormone therapy for 2 to 5 years and want to see if a different pill works better.
San Antonio, TexasAges 18 years+ - NCT07524855RecruitingPhase 1
HLD-0117 study for metastatic breast cancer
This early-stage study tests a new drug called HLD-0117 in women whose metastatic breast cancer (cancer that has spread beyond the breast) has stopped responding to previous hormone and targeted therapies. The goal is to see if this drug can slow or shrink the cancer in patients who have limited options left.
San Antonio, TexasAges 18 years+ - NCT05029999RecruitingPhase 1
Test drugs for HER2-negative advanced breast cancer
This Phase 1 trial tests a combination of immune-targeting drugs (a CD40 medicine and a substance that helps immune cells act) plus chemotherapy in people with HER2-negative advanced breast cancer that has progressed. It aims to find a safer dose and see whether the treatment can shrink tumors or slow the cancer.
San Antonio, TexasAges 18–99 - NCT06058377RecruitingPhase 3
Adding immunotherapy to chemo for stage II-III breast cancer
This trial tests whether adding the immunotherapy drug durvalumab to standard chemotherapy works better than chemo alone for people with hormone receptor positive, HER2 negative breast cancer that is stage II or III and has a high-risk genetic score (MammaPrint High Risk 2).
San Antonio, TexasAges 18 years+ - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
San Antonio, TexasAges 18–60 - NCT04389632RecruitingPhase 1
Sigvotatug vedotin for advanced solid tumors that spread
This early-stage study tests a drug called sigvotatug vedotin in people with advanced solid cancers that cannot be removed or have spread. It aims to see how well the treatment works and what side effects it causes.
San Antonio, TexasAges 18 years+ - NCT06757634RecruitingPhase 3
A study of gedatolisib for first-line advanced breast cancer
This trial tests a new targeted therapy called gedatolisib for people with HR-positive, HER2-negative advanced breast cancer who have not yet received treatment for metastatic disease. It aims to see if adding this drug to standard hormone therapy can help control the cancer longer.
San Antonio, TexasAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
San Antonio, TexasAges 50–70 - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
San Antonio, TexasAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
