Recruiting studies in California
- 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.
Anaheim, CaliforniaAges 18–79 - NCT04510597RecruitingPhase 3
Immunotherapy plus surgery versus immunotherapy alone for kidney cancer
This study tests whether adding surgery to remove the kidney improves outcomes compared with continuing immunotherapy without surgery. It is for people with metastatic kidney cancer whose disease has not worsened after initial immunotherapy.
Arroyo Grande, CaliforniaAges 18 years+ - NCT04389632RecruitingPhase 1
Sigvotatug vedotin for advanced solid tumors that spread
This early-stage study tests a drug called sigvotatug vedotin in people with advanced solid cancers that cannot be removed or have spread. It aims to see how well the treatment works and what side effects it causes.
Anaheim, CaliforniaAges 18 years+ - NCT04429542RecruitingPhase 1
Test of an EGFR-targeting drug for advanced solid cancers
This Phase 1 study tests the safety of BCA101 (an EGFR-targeting treatment) alone or combined with pembrolizumab. It may help people with certain EGFR-driven advanced cancers, depending on the tumor type, prior treatments, and required biopsy testing.
La Jolla, CaliforniaAges 18 years+ - NCT04267848RecruitingPhase 3
Testing immunotherapy with chemo after lung cancer surgery
This trial tests whether adding an immunotherapy medicine to standard chemotherapy after surgery can improve outcomes for some people with non-small cell lung cancer. It may help by boosting the immune system to reduce the chance the cancer comes back.
Anaheim, CaliforniaAges 18 years+ - NCT04333537RecruitingPhase 2/Phase 3
Sentinel node biopsy versus standard neck surgery for early mouth cancer
This trial compares two ways of checking whether early oral cavity squamous cell cancer has spread to neck lymph nodes. It tests whether sentinel lymph node biopsy can find spread as well as standard neck dissection, while potentially reducing more extensive surgery for some people.
San Jose, CaliforniaAges 18 years+ - NCT04181060RecruitingPhase 3
Osimertinib alone or with bevacizumab for EGFR-mutant lung cancer
This Phase 3 trial tests whether starting osimertinib with or without bevacizumab helps people with advanced EGFR-mutant lung cancer live longer and control the cancer better. Your EGFR mutation test result and past treatments are key to whether you can join.
Antioch, CaliforniaAges 18 years+ - NCT04221893Recruiting
Radiation therapy for metastatic gastrointestinal cancers
This trial tests whether adding radiation therapy to your current immunotherapy can help control cancer that has spread in the digestive system. It aims to improve symptoms and possibly slow the cancer's growth.
Walnut Creek, CaliforniaAges 18 years+ - NCT03866382RecruitingPhase 2
Immunotherapy plus a targeted drug for rare genitourinary tumors
This Phase 2 study tests whether nivolumab and ipilimumab (immunotherapy drugs) plus cabozantinib (a targeted anti-cancer drug) can shrink or control rare cancers of the urinary/reproductive system that have spread. It may help by boosting the immune system and blocking cancer growth signals at the same time.
Arroyo Grande, CaliforniaAges 18 years+ - NCT02734537RecruitingPhase 2
Radiation with or without cisplatin after head and neck surgery
This trial studies whether adding cisplatin (a chemotherapy medicine) to radiation therapy helps people with stage III–IVA squamous cell cancer of the head and neck after they’ve had surgery. It’s meant to lower the risk of the cancer coming back.
Merced, CaliforniaAges 18 years+ - NCT07222566RecruitingPhase 3
New drug plus chemotherapy for advanced lung cancer
This trial tests a new study drug called PF-08634404 combined with standard chemotherapy for people with advanced lung cancer that has not been treated before. It aims to see if this combination works better than chemotherapy alone.
Anaheim, CaliforniaAges 18 years+ - NCT06682793RecruitingPhase 1/Phase 2
Study of A2B395 therapy for solid tumors with EGFR and HLA loss
This trial tests a new cell therapy called A2B395 for cancers that have EGFR, a protein on the cell surface, and have lost a specific marker called HLA-A*02. The therapy uses specially engineered immune cells to target and kill these cancer cells. This may help patients with colorectal, lung, head and neck, breast, kidney, or other solid tumors that are no longer responding to standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT06949800RecruitingPhase 2
Probiotics to treat anal precancer (PROTECT trial)
This study tests if a probiotic called EXE-346 can help clear anal high-grade squamous intraepithelial lesions (HSIL), a precancerous condition, in people with HIV who are on effective antiretroviral therapy. If you have anal HSIL that wasn't fully removed by biopsy, you may be able to join.
San Francisco, CaliforniaAges 21 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+ - NCT07224750Recruiting
A blood test to find early signs of gastrointestinal cancer
This study is testing a blood-based test to detect unique molecules (called miRNAs) that may signal the presence of several types of gut or digestive system cancers. The goal is to develop a simple screening tool that could catch these cancers earlier.
Duarte, CaliforniaAges 18 years+ - NCT07219576RecruitingPhase 1/Phase 2
Study of Retifanlimab and Ruxolitinib for Certain Cancers
This trial tests a combination of two drugs, retifanlimab and ruxolitinib, for people with advanced kidney cancer (clear cell renal cell carcinoma) or lung cancer (non-small cell lung carcinoma) whose cancer has grown after previous treatment with a type of immunotherapy called PD-1/PD-L1 inhibitors. The goal is to see if this combination can help when standard treatments are no longer working.
La Jolla, CaliforniaAges Any age - NCT06758401RecruitingPhase 3
Study of combination treatment for advanced lung cancer with high PD-L1
This trial tests a new combination of two medicines (sigvotatug vedotin and pembrolizumab) for people with a type of lung cancer called non-small cell lung cancer (NSCLC) that has high levels of a protein called PD-L1. The treatment is designed to help your immune system fight the cancer more effectively, and this study aims to see how well it works.
Fullerton, CaliforniaAges 18 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors

Beverly Hills, CaliforniaAges 18 years+ - NCT07218003Enrolling by invitationPhase 1
Study of RNDO-564 alone or with pembrolizumab for bladder cancer
This trial tests an experimental drug, RNDO-564, either by itself or combined with another drug (pembrolizumab), for people with advanced bladder cancer or other solid tumors that have stopped responding to standard treatments. The goal is to see if it can shrink tumors or slow cancer growth.
San Francisco, CaliforniaAges 18 years+ - NCT05319730RecruitingPhase 1/Phase 2
Testing new drugs, with or without pembrolizumab, for advanced esophageal cancer
This trial studies investigational cancer medicines, either alone or along with pembrolizumab, for people with advanced esophageal squamous cell cancer whose cancer has grown despite prior immune and platinum-based treatment. It may offer a new option after standard therapy has not worked.
Los Angeles, CaliforniaAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Stanford, CaliforniaAges 18–75 - NCT06465069RecruitingPhase 1
Study of an experimental drug for advanced bladder and other cancers
This trial tests a new drug called LY4052031 for people with advanced or metastatic cancers, especially bladder cancer. The drug aims to slow or stop tumor growth. Doctors will check if it is safe and how well it works.
Duarte, CaliforniaAges 18 years+ - NCT07085091RecruitingPhase 1
Study of ALX2004 for advanced solid tumors

What taking part in a squamous cell carcinoma 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.
