Recruiting studies in California
- NCT04145622RecruitingPhase 1/Phase 2
Ifinatamab deruxtecan for advanced hard-to-treat solid cancers
This early-stage trial tests an investigational antibody-drug medicine (ifinatamab deruxtecan) in people with advanced solid tumors. It aims to see whether it can shrink tumors or help control cancer, and to learn about side effects and the best way to use it.
Los Angeles, CaliforniaAges 18 years+ - NCT04282044RecruitingPhase 1
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+ - 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.
Irvine, CaliforniaAges 12 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.

Givastomig for advanced solid cancers, including gastric and pancreas
This Phase 1 trial tests how safe and effective givastomig (TJ033721) is for advanced or metastatic solid tumors. It may help people whose cancer has grown despite standard treatment, or—if in the combination parts—specific cancers that meet certain lab test and tumor-marker requirements.

Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.
San Diego, CaliforniaAges 18 years+ - NCT05118789RecruitingPhase 1/Phase 2
Study drug for ROS1-positive lung or solid tumors
This Phase 1/2 study tests zidesamtinib (NVL-520), a medicine meant to attack cancers that have a ROS1 genetic change. It’s for people with advanced or metastatic ROS1-rearranged NSCLC (lung cancer) and, in one group, other solid tumors.
Sacramento, CaliforniaAges 12 years+ - NCT05216432RecruitingPhase 1
RLY-2608 for PIK3CA-mutant advanced solid tumors and breast cancer
This early study (Phase 1) tests RLY-2608, a targeted cancer drug for tumors with a PIK3CA mutation. It studies the drug alone and combined with hormone therapy (and sometimes CDK4/6 or CDK4 medicines) to see safety, dose, and whether it can shrink tumors.

Chiauranib for advanced cancers that returned or won’t respond
This Phase 1/2 study tests chiauranib in people with advanced solid cancers (including small cell lung cancer) that have come back or no longer respond to standard treatments. It aims to find a safe dose and see whether the treatment can help shrink tumors.
Encinitas, CaliforniaAges 18 years+ - NCT05315700RecruitingPhase 1/Phase 2
ORIC-114 for advanced lung or breast cancers with EGFR or HER2 changes
This early-phase study tests ORIC-114 to treat advanced solid tumors that have certain EGFR or HER2 genetic changes, often found in lung and breast cancers. It may help by targeting those specific cancer mutations, especially when standard treatments no longer work or aren’t tolerated.

What taking part in a locally advanced solid tumor 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.
