Recruiting studies in California
- NCT06064877RecruitingPhase 3
Study of ficlatuzumab plus cetuximab for advanced head and neck cancer
This trial tests a combination of two drugs, ficlatuzumab and cetuximab, for people with recurrent or metastatic head and neck cancer that is HPV-negative and has not responded to prior immunotherapy and chemotherapy. It aims to see if this combination can help shrink tumors or slow the disease.
Los Angeles, CaliforniaAges 18 years+ - NCT06163534Recruiting
Biomarker profiling study for advanced head and neck cancer patients
This study collects blood and tumor tissue samples to analyze biological markers in patients with advanced head and neck squamous cell carcinoma before starting immunotherapy. The goal is to better understand how these markers relate to treatment response.
Los Angeles, CaliforniaAges 18 years+ - NCT06211335RecruitingPhase 1
Losartan, pembrolizumab and radiation for advanced head & neck cancer
This trial tests a combination of three treatments—a blood pressure drug (losartan), an immunotherapy (pembrolizumab), and targeted radiation—for people with head and neck cancer that has come back, spread to a few spots, or is not responding to other treatments. The goal is to see if this mix can shrink tumors and help patients who have few options left.
Sacramento, CaliforniaAges 18 years+ - NCT06242470RecruitingPhase 1
Study of MGC026 for advanced solid tumors
This trial tests a new drug called MGC026 that targets a protein called B7-H3 on cancer cells, aiming to shrink or slow different advanced solid tumors. It is an early-phase study to find the right dose and check safety.
Los Angeles, CaliforniaAges 18 years+ - NCT06256588RecruitingPhase 3
Dostarlimab vs placebo after chemoradiation for head and neck cancer
This study tests whether the immunotherapy drug dostarlimab, given after standard chemoradiation, can keep advanced head and neck cancer from coming back. It is for people who have not had surgery and whose tumors are PD-L1 positive.
Torrance, CaliforniaAges 18 years+ - NCT06444815RecruitingPhase 1
Study of VET3-TGI for advanced solid tumors
This trial tests an experimental treatment called VET3-TGI, which is injected directly into tumors. It is for people with advanced solid tumors who have already tried other treatments and are looking for new options.
Orange, CaliforniaAges 18 years+ - NCT06525220RecruitingPhase 3
New drug combo vs. standard for head and neck cancer
This trial tests a new combination of two immunotherapy drugs (petosemtamab plus pembrolizumab) compared to pembrolizumab alone for people with head and neck cancer that has spread or come back and cannot be cured locally. It may be an option if your cancer has a certain protein (PD-L1) and you haven't had prior cancer treatment for this stage.
Palo Alto, CaliforniaAges 18 years+ - NCT06532279RecruitingPhase 2
Testing BMX-001 with chemoradiation for head and neck cancer
This trial tests whether adding BMX-001 (a drug that may protect healthy tissues) to standard chemoradiation can reduce side effects and improve outcomes for people with head and neck cancer. It's a randomized study, so you would have a 50/50 chance of getting BMX-001 or a placebo.
Buena Park, CaliforniaAges 18 years+ - NCT06606028Recruiting
Blood test for leftover cancer DNA after head and neck cancer treatment
This study uses a simple blood test to look for leftover cancer DNA after treatment for head and neck squamous cell carcinoma. The goal is to see if the test can find very small amounts of cancer early, which might help doctors make better decisions about follow-up care.
San Francisco, 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+ - NCT06693323RecruitingPhase 2
AHCC supplement with standard therapy for HPV-related head and neck cancer
This trial tests whether adding an AHCC supplement to standard treatment can improve outcomes for people with HPV-positive head and neck cancer. It is for patients who have had surgery and have certain high-risk features, like positive margins or cancer spread to lymph nodes.
Orange, CaliforniaAges 18–79 - NCT06699212RecruitingPhase 3
Light-activated therapy with immunotherapy for head and neck cancer
This trial tests a new light-activated treatment (ASP-1929) combined with an immunotherapy drug (pembrolizumab) as a first treatment for head and neck cancer that has come back in the same area but has not spread to other parts of the body. It aims to see if this combination works better than standard treatment alone.
Duarte, CaliforniaAges 18 years+ - NCT06385080RecruitingPhase 1/Phase 2
Study of amivantamab for head and neck cancer
This trial tests a drug called amivantamab, either alone or with other treatments, for people with head and neck cancer that has spread or come back. The goal is to see if the drug can help shrink tumors or control the cancer.
La Jolla, CaliforniaAges 18 years+ - NCT06535607RecruitingPhase 2
Study of volrustomig for advanced solid tumors
This trial tests a new drug called volrustomig, alone or with other cancer treatments, for people with advanced or metastatic solid tumors. It aims to see if the drug can help shrink or control the cancer.
Los Angeles, 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.
Los Alamitos, CaliforniaAges 18 years+ - NCT06736379RecruitingPhase 1
RNA Therapy Injections for Head and Neck Cancer
This trial tests a new type of immunotherapy made of self-amplifying RNA (saRNA) that produces a protein called IL-12. It's injected directly into head and neck tumors to help your immune system fight the cancer. The study is for people whose cancer has not responded well to standard treatments or who are having surgery to remove their tumor.
Stanford, CaliforniaAges 18 years+ - NCT06778863RecruitingPhase 1
A study of CLSP-1025 for adults with certain solid tumors
This trial tests a new drug called CLSP-1025 for people with advanced solid tumors that have a specific change in the p53 gene (R175H). The drug targets this change to help fight the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06943521RecruitingPhase 1/Phase 2
Study of MT-4561 for advanced solid tumors
This trial tests a new drug called MT-4561 in people with advanced solid tumors that have not responded to prior treatments. It aims to see if the drug can help shrink tumors or slow their growth.

FT836 immune cell therapy for advanced solid tumors
This study tests a new immune cell therapy called FT836, given alone or with chemotherapy or other antibodies, for people with advanced solid tumors that have not responded to previous treatments. The goal is to see if it is safe and helps shrink or control tumors.
La Jolla, CaliforniaAges 18 years+ - NCT00568490Recruiting

What taking part in a head and neck 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.
