About this study
Official title: A Phase Ib Trial of Concurrent Cetuximab (ERBITUX®) and Intensity Modulated Radiotherapy (IMRT) With Ipilimumab (YERVOY®) in Locally Advanced Head and Neck Cancer
This phase Ib trial studies the side effects and best dose of ipilimumab when given together with cetuximab and intensity-modulated radiation therapy (IMRT) in treating patients with previously untreated stage III-IVB head and neck cancer. Monoclonal antibodies, such as ipilimumab and cetuximab, may block tumor growth in different ways by targeting certain cells. Specialized radiation therapy, such as IMRT, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving ipilimumab together with cetuximab and IMRT may kill more tumor cells.
Read the detailed description
PRIMARY OBJECTIVES:
- To identify the starting dose of ipilimumab, in combination with standard cetuximab-IMRT in patients with high- or intermediate-risk, locally advanced head and neck squamous cell carcinoma (HNSCC), for use in a future clinical efficacy trial.
SECONDARY OBJECTIVES:
- To estimate the clinical response of patients with high- or intermediate-risk, locally advanced HNSCC treated with above regimen using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
II. To estimate the 2-year progression-free survival of patients with high- or intermediate-risk, locally advanced HNSCC treated with the above regimen.
III. To investigate serum, lymphocyte and tissue biomarkers as predictors of progression-free survival, toxicity and other outcome parameters in patients with high- or intermediate-risk, locally advanced HNSCC treated with above regimen.
IV. To estimate the association by dose-response modeling between dose of ipilimumab, clinical response and biomarkers.
OUTLINE: This is a dose-escalation study of ipilimumab.
Patients receive cetuximab intravenously (IV) over 60-120 minutes on days 1, 8, 15, and 22. Treatment with cetuximab repeats every 4 weeks for 2 courses. Beginning in week 2 of course 1, patients undergo concurrent IMRT 5 days per week for 7 weeks. Beginning in week 4 (day 1 of course 2) patients also receive ipilimumab IV over 90 minutes once every 21 days for 3 courses. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients achieving disease progression may undergo surgery after completion of therapy.
After completion of study treatment, patients are followed up every 12 weeks for 1 year, every 6 months for 1 year, and then every 12 months for 3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Cetuximab, Intensity-Modulated Radiation Therapy and Ipilimumab in people with Stage III Hypopharyngeal Squamous Cell Carcinoma AJCC v7 and Stage III Laryngeal Squamous Cell Carcinoma AJCC v6 and v7, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of dose limiting toxicities at each dose level assessed using National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (time frame: Up to 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01935921, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2023.
