This study tests a new drug called ficerafusp alfa (BCA101) combined with the immunotherapy pembrolizumab for people with advanced head and neck cancer that has not been treated before. The goal is to see if adding ficerafusp alfa helps shrink tumors better than pembrolizumab alone.
La Jolla, CaliforniaAges 18 years+ - NCT03556228RecruitingPhase 1/Phase 2
Tested medicine for tumors with TrkA changes, alone or with pembrolizumab
This early-phase study tests VMD-928, a targeted cancer medicine, for cancers that have TrkA-related tumor changes. It may be given by itself or with pembrolizumab to see if it can shrink tumors when standard treatments have not worked.
Santa Rosa, CaliforniaAges 18–80 - NCT04392622RecruitingPhase 1
Limonene gelcaps with radiation and chemo to prevent dry mouth
This Phase 1 study tests whether a citrus-flavored supplement (d-limonene gelcaps) can help prevent or reduce dry mouth (xerostomia) in people getting radiation plus chemotherapy for certain head and neck cancers. It aims to see how well the approach is tolerated and whether it can protect saliva function during treatment.
Stanford, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Santa Monica, CaliforniaAges 18 years+ - NCT05877430RecruitingPhase 1/Phase 2
Testing an anti-cancer drug plus pembrolizumab for advanced cancers
This Phase 1/2 study tests the safety and early signs of benefit from CJRB-101 when combined with pembrolizumab (Keytruda) in people with advanced or metastatic lung, head and neck, or melanoma cancer. It may help some participants, but the main goal is to see how safe the combination is and whether it can control cancer.
Irvine, 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+ - 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+ - 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+ - NCT06789172RecruitingPhase 1
New drug OKN4395 with or without pembrolizumab for solid tumors
This trial tests a new oral drug called OKN4395, which targets a COX2-related immune pathway, alone or with the immunotherapy pembrolizumab, in people with advanced solid tumors. It may be an option if you have certain types of cancer that have stopped responding to other treatments.
Santa Monica, 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.

What taking part in a hnscc 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.
