Recruiting studies near San Diego
- NCT06625775RecruitingPhase 1
Study of BBO-10203 for advanced solid tumors
This trial tests a new drug called BBO-10203, alone or combined with other cancer treatments, for people with certain advanced breast, colorectal, or lung cancers. It aims to see if the drug is safe and effective.
San Diego, CaliforniaAges 18 years+ - NCT07144280RecruitingPhase 3
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+ - NCT06632977RecruitingPhase 2
Matching targeted treatments to your prostate cancer's genetics
This trial is testing whether matching your cancer's specific genetic changes to a targeted treatment can help control metastatic prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. You may receive a drug, a radioactive treatment, or a combination based on your tumor's molecular profile.
San Diego, CaliforniaAges 18 years+ - NCT07046260Recruiting
Blood test study for early cancer detection
This study is testing a new blood test to help doctors find cancer earlier. If you are 45 or older and have symptoms that might be cancer, or were recently diagnosed with cancer, you may be able to join.
San Diego, CaliforniaAges 45 years+ - NCT03869814Recruiting
Blood test to study cancer signals without invasive procedures
This study looks at a non-invasive blood test to detect cancer-related “signal patterns” and see how well they match different types of cancer. It may help researchers learn better ways to find or understand cancer using less invasive testing.
San Diego, CaliforniaAges 21–80 - NCT06616584RecruitingPhase 2/Phase 3

San Diego, CaliforniaAges 18 years+ - NCT06031688RecruitingPhase 2
Targeted treatment for lung cancer with a MET gene change
This trial tests a targeted drug for advanced non-small cell lung cancer that has a specific genetic change called MET exon 14 skipping. It aims to see if the drug can shrink tumors or slow the cancer's growth, and may help people who have or haven't had prior treatment.
San Diego, CaliforniaAges 18 minutes+ - NCT07124000Recruiting
T-DXd for advanced HER2-positive solid tumors
This trial is for people with advanced HER2-positive solid tumors (cancers that cannot be removed by surgery or have spread). It tests the drug T-DXd (also called Enhertu) when your doctor has already decided it's the right treatment for you and you have no other good options.
San Diego, CaliforniaAges 18–130 - NCT07543757Recruiting

This study tests a new blood test (Proclarix) that may help doctors decide if a prostate biopsy is needed. It is for men with a slightly elevated PSA who are already considering a biopsy.
San Diego, CaliforniaAges 40–75 - NCT04671667RecruitingPhase 2
Pembrolizumab vs chemo-radiation after surgery for recurrent head/neck cancer
This trial tests whether pembrolizumab (an immunotherapy drug) works better than the usual chemo plus radiation after surgery for cancer that has come back in the head and neck area. It may help reduce cancer returning or spreading by using your immune system, but eligibility depends on how the cancer came back and your prior treatments.
San Diego, CaliforniaAges 18–79 - NCT06577883Recruiting
New chest X-ray technique for lung cancer screening
This trial tests a new type of chest X-ray called tomosynthesis to improve lung cancer screening. It looks at people who are getting screened for lung cancer, have a suspicious spot on their lung, or have just been diagnosed—as long as they haven't been treated for lung cancer before.
San Diego, CaliforniaAges 30–85 - NCT06906562RecruitingPhase 2
Pemigatinib for advanced pancreatic cancer with FGFR changes
This trial tests a targeted pill, pemigatinib, for people with advanced pancreatic cancer that has a specific FGFR gene change. The study is done entirely through telemedicine, so you can participate from home if eligible.
San Diego, 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 Diego, CaliforniaAges 18–60 - NCT05579366RecruitingPhase 1/Phase 2
Study of rinatabart sesutecan for advanced solid tumors
This trial tests an investigational drug called rinatabart sesutecan (also known as Rina-S) for people with advanced solid tumors, including ovarian, endometrial, lung, breast, and other cancers. The drug is designed to target and kill cancer cells, and the study aims to see if it is safe and effective.
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+ - NCT07005154RecruitingPhase 2
Study of ASP5541 for metastatic prostate cancer
This study tests an experimental drug called ASP5541 for men with metastatic prostate cancer (either hormone-sensitive or castration-resistant). It aims to see if the drug can slow cancer growth and improve outcomes when added to standard hormone therapy.
San Diego, CaliforniaAges 18 years+ - NCT06324357RecruitingPhase 1/Phase 2
Zongertinib for HER2-positive cancers that have spread
This trial tests a new pill called zongertinib, alone or with other drugs, for people with HER2-positive cancers (like breast, stomach, or colorectal cancer) that have spread and are no longer responding to standard treatments. The goal is to find the best dose and see if it can help shrink tumors or slow the disease.
San Diego, CaliforniaAges 18 years+ - NCT06580314RecruitingPhase 3
Olaparib with or without bevacizumab for ovarian cancer
This trial tests whether taking the drug olaparib for one or two years, alone or with another drug called bevacizumab, can help keep ovarian cancer from coming back after initial chemotherapy and surgery. It is for people with certain genetic markers in their tumor.
San Diego, CaliforniaAges 18 years+ - NCT06728579RecruitingPhase 2
Group therapy for joint pain in breast cancer survivors
This study tests two supportive group programs—one using mindfulness skills, the other providing supportive talk therapy—to help breast cancer survivors manage joint pain caused by hormone-blocking pills. If you have ongoing joint pain and are taking an aromatase inhibitor, you may be able to join a free, video-based group.

Study for HER2-positive bladder cancer after limited treatment
This Phase 2 trial tests disitamab vedotin alone or with pembrolizumab for urothelial (bladder/urinary tract) cancer that has HER2-positive tumors. It aims to shrink tumors and improve outcomes, including for people who have had limited prior treatment or specific prior drug exposures.
San Diego, CaliforniaAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
San Diego, CaliforniaAges 18 years+ - NCT04184973Recruiting
Testing a colon bypass device during colorectal cancer surgery
This trial studies a device (CG-100) placed inside the bowel to see if it can improve safety and outcomes during surgery for colorectal cancer. You would be asked to follow extra study check-ins after your operation, and the team would monitor whether the device works as intended.

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.
