- NCT06974110RecruitingPhase 1
Study of a new drug for advanced solid tumors with MSI-H or dMMR

San Diego, CaliforniaAges 18 years+ - NCT05994482Recruiting
Surveillance colonoscopy study in older veterans
This study looks at how often older veterans (age 75 and older) should get a follow-up colonoscopy after having polyps removed. Researchers will review medical records and talk to patients and doctors to help create better guidelines for surveillance colonoscopies in older adults.
San Diego, CaliforniaAges 75 years+ - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
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.
San Diego, CaliforniaAges 18 years+ - NCT06906562RecruitingPhase 2
Pemigatinib for advanced pancreatic cancer with FGFR changes

San Diego, CaliforniaAges 18 years+ - NCT04628767RecruitingPhase 2/Phase 3
Durvalumab plus chemo before surgery for upper tract cancer
This trial tests whether adding an immunotherapy drug (durvalumab) to chemotherapy before surgery can improve outcomes for people with high-grade upper tract urothelial cancer. It compares different treatment approaches based on whether a patient can receive cisplatin chemotherapy.
San Diego, CaliforniaAges 18 years+ - NCT06134232RecruitingPhase 2
Extra sipuleucel-T after Provenge for prostate cancer
This trial tests whether adding one extra infusion of sipuleucel-T (the same drug as Provenge) after the standard three doses can help men with advanced prostate cancer that no longer responds to hormone therapy. It is for men who have already finished their three Provenge infusions and have mild or no symptoms.
San Diego, CaliforniaAges 18 years+ - NCT06543576RecruitingPhase 1/Phase 2
Radiation and drug therapy for stage IVB cervical cancer
This trial tests combining external and internal radiation with chemotherapy and immunotherapy for stage IVB cervical cancer that has not been treated before. The goal is to see if this approach can help shrink tumors and improve outcomes.

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+ - NCT06513962RecruitingPhase 3
Triptorelin to protect ovaries in young women with cancer
This study tests whether a medicine called triptorelin can protect the ovaries in young women and teens receiving strong chemotherapy for cancer. If you are newly diagnosed with a cancer (other than breast cancer) and are about to get certain chemotherapy drugs, this trial may help preserve your fertility.
San Diego, CaliforniaAges Up to 39 years - NCT06917079RecruitingPhase 1
BBO-11818 for KRAS-mutated cancers
This trial tests a new oral drug (BBO-11818) for people with solid tumors that have a specific KRAS mutation. It's for those whose cancer has spread or cannot be removed by surgery and who have not had other cancers recently.
San Diego, CaliforniaAges 18 years+ - NCT05856773RecruitingPhase 3
Standard vs shorter radiation to lymph nodes for breast cancer
This trial compares two ways of giving radiation to the breast/chest wall and nearby lymph nodes after breast surgery: a standard schedule versus a shorter “hypofractionated” schedule. It uses proton therapy and may help reduce treatment time while still controlling the cancer.
San Diego, CaliforniaAges 19 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+ - 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+ - NCT07421700RecruitingPhase 1/Phase 2
Study of PF-08634404 alone or with enfortumab vedotin for bladder cancer
This trial tests a new drug, PF-08634404, either by itself or together with another drug called enfortumab vedotin, for people with advanced bladder cancer that has spread. The goal is to see if these treatments can shrink tumors or slow the cancer's growth.
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+ - NCT04363164RecruitingPhase 2
Testosterone then enzalutamide to stop prostate cancer spread
This Phase 2 trial tests whether giving testosterone first, then enzalutamide (a prostate cancer hormone-blocking pill), can slow or prevent worsening metastatic prostate cancer. It is designed for men whose cancer progressed despite ongoing hormone-suppression treatment.
San Diego, CaliforniaAges 18–90 - NCT06545955RecruitingPhase 3
Gene therapy study for high-grade bladder cancer not responding to BCG
This trial tests a gene therapy called nadofaragene firadenovec, given directly into the bladder, either alone or with chemo or immunotherapy. It's for people with high-grade bladder cancer that hasn't gone away after BCG treatment.
San Diego, CaliforniaAges 18 years+ - NCT06995677RecruitingPhase 2
TYRA-300 pill for low-grade bladder cancer with FGFR3 change
This study tests an experimental pill called TYRA-300 for people with low-grade bladder cancer that hasn't spread into the muscle layer. The pill targets a specific gene change (FGFR3) found in the tumor. The goal is to see if it can slow or shrink the cancer.
San Diego, CaliforniaAges 18 years+ - NCT06931340RecruitingPhase 3
Adding chemo to hormone therapy for advanced prostate cancer
This trial is for men with metastatic prostate cancer that has already spread beyond the pelvis. It tests whether adding a chemotherapy drug (docetaxel) to the usual hormone therapy plus apalutamide can help control the cancer better than hormone therapy alone.
San Diego, CaliforniaAges 18 years+ - NCT05705219Recruiting
3D ultrasound scan to guide treatment decisions in liver cancer
This study tests whether a special 3D ultrasound scan (using contrast) can help support decisions for people with colorectal cancer that has spread to the liver. If you have planned new cancer treatment, the scan may add information to help doctors guide care.

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.
