Recruiting studies in California
- NCT06841354RecruitingPhase 3
Sac-TMT alone or with pembrolizumab for advanced triple-negative breast cancer
This trial tests a new drug, Sac-TMT, given alone or with an immunotherapy drug (pembrolizumab) for people with advanced triple-negative breast cancer who have not yet received any treatment for advanced disease. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Duarte, CaliforniaAges 18 years+ - NCT06103864RecruitingPhase 3
Study of Dato-DXd with or without durvalumab for advanced triple-negative breast cancer
This trial is testing whether a new drug combination (Dato-DXd with or without durvalumab) works better than standard chemotherapy plus pembrolizumab for people with a certain type of advanced triple-negative breast cancer that has a protein called PD-L1. The study aims to find a more effective treatment option for this specific group.
Duarte, CaliforniaAges 18 years+ - NCT05985655RecruitingPhase 1/Phase 2
Study of GTAEXS617 for advanced solid tumors
This trial tests a new drug called GTAEXS617 for adults with certain advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT04768426RecruitingPhase 2
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+ - 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+ - NCT07741968Recruiting

Arcadia, CaliforniaAges 18 years+ - NCT06966700RecruitingPhase 3
Study of Sac-TMT in Early High-Risk Breast Cancer
This study tests a new drug called Sacituzumab Tirumotecan (Sac-TMT) for people with early-stage, high-risk breast cancer that hasn't spread. The drug is given before surgery to see if it can shrink tumors and improve outcomes.
Burbank, 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+ - NCT06827613RecruitingPhase 1/Phase 2
Study of invikafusp alfa plus sacituzumab govitecan for advanced solid tumors
This trial tests a new drug combination for people with advanced breast cancer (triple-negative or hormone receptor-positive). The goal is to see if the combination helps shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT05812807RecruitingPhase 3
Pembrolizumab versus monitoring after triple-negative breast cancer response
This trial checks whether giving pembrolizumab (an immunotherapy) after surgery helps people with triple-negative breast cancer reduce the chance of the cancer coming back, compared with close monitoring only. It’s for patients who had no remaining invasive cancer after neoadjuvant chemotherapy plus pembrolizumab.
Arroyo Grande, CaliforniaAges 18 years+ - NCT05929768RecruitingPhase 3
Shorter chemo plus immunotherapy without anthracyclines for early TNBC
This Phase 3 trial tests whether a shorter course of chemotherapy plus immunotherapy can work as well as standard treatment for early-stage triple-negative breast cancer. It avoids anthracycline drugs and may help reduce exposure to those medicines if the shorter plan is effective and safe.
Berkeley, CaliforniaAges 18 years+ - NCT06465069RecruitingPhase 1
Study of a new drug for advanced bladder and other solid tumors
This study tests a new drug (LY4052031) for people with several types of advanced solid tumors, especially bladder cancer. It aims to see if the drug is safe and effective when given alone or after other treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT07173751RecruitingPhase 3
Pumitamig for advanced triple-negative breast cancer
This study tests a new drug called pumitamig for people with a type of breast cancer that is triple-negative or has very low hormone receptors and has come back or spread. It aims to see if pumitamig works better than standard treatment and how safe it is for people who cannot get PD(L)-1 immunotherapy with chemo.
La Jolla, CaliforniaAges 18 years+ - NCT06562192RecruitingPhase 1
Testing a radioactive drug for advanced pancreatic, lung, breast, and colorectal cancers
This trial tests a new radioactive drug (177Lu-NNS309) for people with advanced pancreatic, lung, breast, or colorectal cancer that has not responded to prior treatments. It aims to see if the drug can target and shrink tumors.
Los Angeles, CaliforniaAges 18–100 - NCT05208762RecruitingPhase 1
PD-L1 antibody drug study for advanced lung and head/neck cancers
This Phase 1 trial tests a new experimental drug (PF-08046054/SGN-PDL1V) in people with advanced solid tumors that have not responded to standard treatment or can’t use it. It is designed to see how the drug works and how safe it is, with a focus on tumors that have PD-L1 seen on prior lab testing.
Irvine, CaliforniaAges 18 years+ - NCT07318805RecruitingPhase 1

Duarte, CaliforniaAges 18 years+ - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer

Individualized vaccine added to standard treatment for metastatic triple-negative breast cancer
This Phase 2 trial tests whether adding a personalized cancer vaccine to durvalumab (an immunotherapy), tremelimumab (another immunotherapy), and chemotherapy can improve outcomes for people with metastatic triple-negative breast cancer. It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 18 years+ - NCT03808337RecruitingPhase 2

CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Stanford, CaliforniaAges 18 years+ - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04510129Recruiting
Cancer biospecimen collection study for immunotherapy patients
This study collects samples (like tissue biopsies and imaging information) from people with certain cancers who are starting anti–PD-1/PD-L1 immunotherapy. It helps researchers gather material to study how these treatments work.

What taking part in a triple negative breast cancer 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.
