About this study
Official title: Multicenter Randomized Phase II Study of Erlotinib, Cisplatin and Radiotherapy Versus Cisplatin and Radiotherapy in Patients With Stage III and IV Squamous Cell Carcinoma of the Head and Neck
This randomized phase II trial is studying cisplatin and radiation therapy together with or without erlotinib hydrochloride to compare how well they work in treating patients with stage III or stage IV head and neck cancer. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may also make tumor cells more sensitive to radiation therapy. Giving cisplatin and radiation therapy together with erlotinib hydrochloride may kill more tumor cells. It is not yet known whether cisplatin and radiation therapy are more effective with or without erlotinib hydrochloride in treating head and neck cancer
Read the detailed description
PRIMARY OBJECTIVES:
- Compare the complete response rate in patients with locally advanced head and neck cancer, treated with cisplatin, radiotherapy and erlotinib (erlotinib hydrochloride) versus cisplatin and radiotherapy alone.
SECONDARY OBJECTIVES:
- Evaluate whether the addition of erlotinib increases the acute and long term toxicities of cisplatin and radiotherapy, in patients with locally advanced head and neck cancer.
II. Compare the disease-free and overall survivals of patients with locally advanced head and neck cancer treated with cisplatin and radiotherapy, with and without erlotinib.
III. Evaluate whether the symptomatic improvement observed in the first week of erlotinib alone predicts for complete response and long term disease control.
IV. Correlate epidermal growth factor receptor (EGFR), p16 and excision repair cross-complementing 1 (ERCC-1) expression with response outcome to therapy with cisplatin and radiation with and without erlotinib.
- Identify other molecular correlates that may be relevant in the pathogenesis of squamous cell carcinoma of head and neck (SCCHN) or response to therapy.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive cisplatin intravenously (IV) on days 1, 22, and 43 and undergo 3-dimensional conformal or intensity modulated radiotherapy once daily, 5 days per week, on days 1-47. Patients also receive erlotinib hydrochloride orally (PO) once daily (QD) on days -7 to 47.
ARM II: Patients receive cisplatin and undergo radiotherapy as in Arm I.
Within 10-14 weeks after completion of study treatment, patients with N2 or N3 disease at the time of screening undergo a neck dissection.
After completion of study treatment, patients are followed up periodically for 5 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Comparison of the Percentage of Participants With a Complete Response in Each Treatment Arm
Complete response requires both a pathological complete response (independent of observer) and a complete response radiologically (RECIST 1.0).
Measured: 12 weeks after the completion of therapy
Secondary outcomes (2)
Safety as Assessed Through Summaries of Adverse Events and Laboratory Test Results by Treatment Arm
Measured: 30 days after the completion of therapy
Progression Free Survival of Patients With Locally Advanced Head and Neck Cancer Treated With Cisplatin and Radiotherapy, With and Without Erlotinib Hydrochloride
Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
Measured: Every 3 months for up to 5 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing erlotinib hydrochloride, cisplatin and 3-dimensional conformal radiation therapy in people with Stage III Squamous Cell Carcinoma of the Hypopharynx and Stage III Squamous Cell Carcinoma of the Larynx, run by University of Washington at 9 sites 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 13 inclusion and 10 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 10 May 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Apr 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Comparison of the Percentage of Participants With a Complete Response in Each Treatment Arm (time frame: 12 weeks after the completion of therapy). 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 NCT00410826, which also lists 3 linked publications.
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 10 May 2013; AzTrials last refreshed its copy on 8 Nov 2026.
