Recruiting studies in California
- NCT07287917RecruitingPhase 1/Phase 2
Testing a new drug combo for advanced breast cancer or melanoma
This trial tests a new combination of drugs (AMXT 1501, DFMO, and standard therapies) for people with advanced solid tumors, specifically breast cancer (ER+ HER2-) or melanoma that has progressed after other treatments. The goal is to see if this combination can help shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - 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 Francisco, CaliforniaAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 3
Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Cerritos, CaliforniaAges 18 years+ - NCT06022029RecruitingPhase 1
Study of injected ONM-501 alone or with cemiplimab for advanced cancers
This trial tests an injected study drug (ONM-501) alone or with another drug (cemiplimab) for people with advanced solid tumors or lymphomas that haven't responded to other treatments. It aims to find a safe dose and see if the combination helps shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06393374RecruitingPhase 3
Study of a new drug combination for residual TNBC after initial treatment
This trial tests a new combination of two drugs (sacituzumab tirumotecan and pembrolizumab) compared to standard chemotherapy for people with triple-negative breast cancer that did not fully respond to initial treatment. It aims to see if this combination helps prevent cancer from coming back.
Fountain Valley, CaliforniaAges 18 years+ - NCT03053193Recruiting
Testing gene activity to guide breast cancer treatment
This study links breast tumor test results from MammaPrint and optional BluePrint (and full genetic data) with real-world clinical information to understand which new gene activity patterns matter. It may help future patients by improving how doctors use these tests to guide care.
Redding, CaliforniaAges 18 years+ - NCT04049214Recruiting
Mindfulness program during breast cancer surgery
This trial tests whether a structured mindfulness program before and after breast cancer surgery can reduce stress and improve how patients feel and cope. You may be offered mindfulness materials to use around the time of your operation.
Newport Beach, CaliforniaAges 18 years+ - NCT06123286RecruitingEarly Phase 1
Tart cherry and omega-3s for joint pain from hormone therapy
This study tests whether taking tart cherry and omega-3 supplements can help reduce joint pain and stiffness caused by aromatase inhibitors (a common breast cancer treatment). If you have bothersome joint pain while on this hormone therapy, you may be able to join.
Los Angeles, CaliforniaAges 18 years+ - NCT06353997RecruitingPhase 2
New immunotherapy combination before surgery for triple-negative breast cancer
This trial tests a new combination of two immunotherapy drugs (INBRX-106 and pembrolizumab) given before surgery for people with early-stage triple-negative breast cancer. The goal is to see if this treatment can shrink the tumor and improve outcomes.
Los Angeles, CaliforniaAges 18 years+ - NCT06908928RecruitingPhase 1
Study of Bulumtatug Fuvedotin for advanced triple-negative breast cancer
This study tests a new drug called bulumtatug fuvedotin for people with triple-negative breast cancer that has spread or come back. It's for those who have already tried certain other treatments, including a taxane and a specific type of antibody-drug conjugate.
La Jolla, CaliforniaAges 18 years+ - NCT05978128Recruiting
Use advocates to boost lung cancer screening
This trial tests whether trained advocates and supporters can help people who are eligible for lung cancer screening actually get screened. It may help you (and others) by making screening easier to plan and complete.
Los Angeles, CaliforniaAges 40–80 - NCT07310004Recruiting
VR vs Music for Breast Biopsy Anxiety
This trial compares using a virtual reality headset versus listening to relaxing music to help lower your anxiety and pain during a breast biopsy. Both methods are non-drug ways to help you feel more comfortable during the procedure.
Los Angeles, CaliforniaAges 18 years+ - NCT06126276RecruitingPhase 2
Testing neratinib with or without palbociclib for HER2+ solid tumors
This trial tests two targeted drugs—neratinib alone or with palbociclib—for people with HER2-positive solid tumors (other than breast cancer) that have returned or not gone away. The goal is to see if blocking HER2 and CDK4/6 can shrink or slow the tumor.

What taking part in a breast cancer female 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.
