Lattice-Based Radiotherapy and Chemoimmunotherapy for Oropharyngeal Squamous Cell Carcinoma
United States60 participantsStarted 2026-05
Plain-language summary
This single-arm Phase I/II trial evaluates induction chemoimmunotherapy combined with lattice radiotherapy (LRT) in patients with non-low risk oropharyngeal squamous cell carcinoma and primary tumor ≥3 cm or primary tumor and pathologic lymph node ≥3 cm in longest dimension. BOIN12 adaptive dose-finding will guide dose across two anatomical cohorts-primary-tumor only (P) and primary + largest involved node (PN)-with a total target accrual of about 60 evaluable patients.
Dose-limiting toxicity is monitored separately in each cohort. If both tolerate the same dose, that unified optimal biological dose (OBD) advances to Phase II; if tolerability differs, the PN-specific OBD expands while the P cohort is analyzed descriptively.
After induction, imaging determines response: patients achieving ≥50% volumetric tumor shrinkage receive hypofractionated chemoradiation, whereas those with \<50% shrinkage are treated with conventional fractionation, personalizing definitive therapy according to early safety and efficacy signals.

Exclusion criteria
. Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months;
. Transmural myocardial infarction within the last 6 months;
. Acute bacterial or fungal infection intravenous antibiotics at the time of registration;
. Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy within 30 days of registration;
. Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects; note, however, that laboratory tests for liver function and coagulation parameters are not required for entry into this protocol other than those listed in 5.1.
. Acquired immune deficiency syndrome (AIDS) based upon the current CDC definition with immune compromise greater than that noted in section 5.1; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive. Protocol-specific requirements may also exclude immune-compromised patients.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
