Recruiting studies near San Diego
- NCT05929768RecruitingPhase 3

San Diego, CaliforniaAges 18 years+ - NCT06592924RecruitingPhase 3
Adding chemo to hormone therapy for prostate cancer with slow PSA drop
This trial tests if adding docetaxel chemotherapy helps men whose PSA hasn't dropped enough after at least 6 months of standard hormone therapy (ADT) plus an ARPI pill (like abiraterone or enzalutamide) for metastatic prostate cancer that still responds to hormones.
San Diego, CaliforniaAges 18 years+ - NCT07100106RecruitingPhase 1/Phase 2
Study of GDC-4198 alone or with giredestrant for advanced breast cancer
This trial tests a new treatment (GDC-4198) alone or with another drug (giredestrant) compared to a standard combination (abemaciclib and giredestrant) for people with advanced hormone receptor-positive, HER2-negative breast cancer that has progressed after previous treatments.
San Diego, CaliforniaAges 18 years+ - NCT06162221RecruitingPhase 1/Phase 2
Study of RAS inhibitors for advanced RAS-mutated lung cancer

San Diego, CaliforniaAges 18 years+ - NCT04205968RecruitingPhase 2
Testing ramucirumab with chemo for advanced small bowel cancer
This trial studies whether adding ramucirumab to chemotherapy (either paclitaxel or FOLFIRI) works better for advanced small bowel adenocarcinoma that has already been treated with certain prior medicines. It may help shrink tumors or slow cancer growth in people whose cancer has progressed.
San Diego, CaliforniaAges 18 years+ - NCT06031688RecruitingPhase 2

San Diego, CaliforniaAges 18 years+ - NCT06172296RecruitingPhase 3
Dinutuximab plus transplant for high-risk neuroblastoma
This trial tests adding a targeted drug called dinutuximab to standard chemotherapy, surgery, and a stem cell transplant for children and young adults with a new diagnosis of high-risk neuroblastoma. The goal is to see if this combination helps more patients stay in remission.
San Diego, CaliforniaAges Up to 30 years - NCT05746182Recruiting
Genetic testing program for pancreatic neuroendocrine tumors

San Diego, CaliforniaAges 18 years+ - NCT05208047RecruitingPhase 3
CGT9486 plus sunitinib for advanced gastrointestinal stromal tumors
This trial tests whether adding a new drug called CGT9486 to sunitinib (a standard cancer drug) works better than sunitinib alone for gastrointestinal stromal tumors (GISTs) that have grown or spread. You may qualify if your GIST stopped responding to or caused problems with imatinib, an earlier treatment.
San Diego, CaliforniaAges 18 years+ - NCT06767514RecruitingPhase 3
Ivonescimab for first-line treatment of advanced NSCLC with high PD-L1
This trial tests a new drug called Ivonescimab as the first treatment for people with advanced (stage IV) non-small cell lung cancer whose tumors have high levels of PD-L1 (a protein that helps cancer hide from the immune system). The goal is to see if it can help shrink or control the cancer.
San Diego, CaliforniaAges 18 years+ - NCT06627647RecruitingPhase 3
Comparing two immunotherapy drugs for advanced lung cancer
This trial tests a new immunotherapy drug, rilvegostomig, against the standard pembrolizumab, both given with chemotherapy, as a first treatment for advanced non-squamous non-small cell lung cancer (NSCLC) that cannot be cured with surgery or radiation. It is for people whose tumors have high PD-L1 levels and do not have certain genetic mutations.
San Diego, 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.
San Diego, CaliforniaAges 18 years+ - NCT05174169RecruitingPhase 2/Phase 3
Adjuvant colon chemotherapy guided by tumor DNA results
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
San Diego, CaliforniaAges 18 years+ - NCT07061977RecruitingPhase 3
New cancer drug combo for advanced cervical cancer
This trial tests if giving the immunotherapy drug pembrolizumab before and after standard chemoradiation works better than the standard approach for people with high-risk cervical cancer that has spread locally.
San Diego, CaliforniaAges 18 years+ - NCT06934239RecruitingPhase 4
AI-assisted vs. standard mammograms for breast cancer screening
This trial compares standard mammograms with mammograms aided by artificial intelligence (AI) to see if AI helps find breast cancer more accurately and reduces unnecessary callbacks. If you're 18 or older and getting a routine screening mammogram at one of the six participating health systems, you may be eligible.

Study of a new drug vs docetaxel for advanced lung cancer
This trial tests a new experimental drug called PF-08046054/SGN-PDL1V against a standard chemotherapy (docetaxel) for people with a type of advanced lung cancer that has PD-L1 protein on at least 1% of tumor cells and has progressed after prior treatments. The goal is to see if the new drug works better or has fewer side effects.
San Diego, CaliforniaAges 18 years+ - NCT06982521RecruitingPhase 3
Comparing two drug combinations for advanced breast cancer
This trial tests two different combinations of medicines for people with a certain type of advanced breast cancer (HR-positive, HER2-negative) that has a specific gene change called PIK3CA. The goal is to see which combination is better at slowing down the cancer.
San Diego, CaliforniaAges 18 years+ - NCT04269902RecruitingPhase 3
Early treatment check for high-risk CLL/SLL
This Phase 3 trial studies an early treatment approach for people with high-risk CLL or SLL who have not yet needed standard therapy. It aims to see if treating earlier can improve outcomes while keeping side effects manageable.
San Diego, CaliforniaAges 18 years+ - NCT05455619RecruitingPhase 1/Phase 2
Targeted drugs for PI3K-altered, HR+/HER2- breast cancer
This Phase 1/2 trial tests how well a combination of targeted medicines works for advanced or returning HR+/HER2- breast cancer that has a PI3K pathway change (such as PIK3CA, PTEN, or AKT1). It may help by blocking growth signals in the cancer and is especially for people whose cancer has progressed after hormone therapy and a CDK4/6 inhibitor.

What taking part in a 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.
