Recruiting studies near San Francisco
- 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 Francisco, CaliforniaAges 50–70 - NCT06224673RecruitingPhase 2
Testing ARX788 for HER2-low advanced breast cancer
This trial tests a new drug, ARX788, for people with HER2-low breast cancer that has spread or cannot be removed by surgery. The goal is to see if ARX788 helps shrink or control the cancer.
San Francisco, CaliforniaAges 18 years+ - NCT07391774RecruitingPhase 3
Hormone therapy with or without chemo for early breast cancer
This trial tests whether skipping chemotherapy and using only hormone therapy with a drug called ribociclib works as well as chemotherapy followed by hormone therapy with ribociclib for certain early breast cancers that have a low risk of coming back.
San Francisco, CaliforniaAges 18 years+ - 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 Francisco, CaliforniaAges 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 Francisco, CaliforniaAges 18–60 - NCT06586957RecruitingPhase 1
Study of NKT3964 for advanced solid tumors
This trial is testing an experimental oral drug called NKT3964 for people with advanced solid tumors that have stopped responding to standard treatments. The drug works by blocking a protein called CDK2, which some cancers need to grow.
San Francisco, CaliforniaAges 18 years+ - NCT04665739RecruitingPhase 2
Lutetium Lu-177 for lung carcinoid tumors with somatostatin receptors
This trial tests lutetium Lu 177 dotatate, a targeted radiation treatment, for advanced lung neuroendocrine (carcinoid) tumors that have a specific marker called somatostatin receptors. It may help shrink tumors by delivering radiation directly to cancer cells that “light up” on a special scan.
San Francisco, CaliforniaAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Greenbrae, CaliforniaAges 18 years+ - NCT06790693RecruitingPhase 3
Inavolisib plus hormone therapy for advanced breast cancer
This trial tests a new targeted therapy, inavolisib, combined with standard hormone therapy and a CDK4/6 inhibitor for people with a specific genetic mutation (PIK3CA) in their hormone receptor-positive, HER2-negative advanced breast cancer that has not been treated before. It compares this combination to a placebo plus the same standard treatments.
San Mateo, CaliforniaAges 18 years+ - NCT05059444Recruiting
Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.
Redwood City, CaliforniaAges 18 years+ - NCT07213791RecruitingPhase 1
Study of a new drug for FAP-positive cancers
This trial tests a new drug (LY4337713) for cancers that have a specific protein called FAP on their surface. It may be an option for people whose cancer has continued to grow after standard treatments.

What taking part in a hormone receptor positive breast carcinoma study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
