About this study
Official title: Phase II Study of TARCEVA (Erlotinib) as Adjuvant Treatment for Locally Advanced Head and Neck Squamous Cell Carcinoma With Evaluation of Neoadjuvant Biomarker Modulation With TARCEVA vs. TARCEVA Plus Sulindac
This trial was originally designed and powered to compare biomarker modulation in the neo-adjuvant setting (erlotinib versus erlotinib plus sulindac versus placebo) with clinical response to erlotinib in the adjuvant setting. Since implementing the trial in late 2005, The investigators have encountered significant obstacles to implementing the adjuvant therapy phase of the trial.
- Barriers included:
Read more
- disease recurrence
- patient refusal to take the agent
- patient refusal to travel to Pittsburgh for clinical evaluations.
Given the institutional challenges to implement and complete the adjuvant portion, the investigators have decided to change the primary endpoint to a biomarker modulation endpoint. To achieve this goal, the investigators determined that they needed 39 paired tissue specimens (see statistical justification below).
The central hypothesis to be tested in this study is that persistent activation of parallel and/or downstream pathways contributes to tumor progression in the setting of EGFR blockade. While not all head and neck squamous cell carcinoma (HNSCC) patients will respond to EGFR targeting, the optimal strategy to identify those subjects whose tumors are sensitive to EGFR inhibition remains unknown.
The primary objective is centered around the concept of tumor biomarkers which may be modulated by EGFR and Cox-2 inhibitors and may serve as future therapeutic targets for therapy. To this end patients on this trial will be randomly assigned to one of three arms to receive either Tarceva, Tarceva plus sulindac, or a placebo in the 2 week pre-operative period. A panel of biomarkers will be obtained by biopsy prior to pre-operative therapy and again at surgery. Biomarkers will be examined for modulation in the 2-week pre-operative period, for group differences, for treatment effects and for further understanding of protein signaling pathways.
Sample size for the primary objective
Modification of Statistical Design:
The primary endpoint is the difference between pre (biopsy) and post (surgery). There are 3 hypotheses of interest: (1) placebo vs erlotinib alone, (2) placebo versus erlotinib plus sulindac, and (3) erlotinib vs erlotinib + sulindac. With a randomization in a 3:5:5 ratio, we have 88% power, alpha = .01 for an omnibus test to show between-group differences of 1 log exist. This requires 39 patients. Basically, 39 patients will provide the ability to detect a one log difference between any 2 of the 3 groups in pre-post change.
Read the detailed description
Head and neck squamous cell carcinoma (HNSCC) constitutes 3 percent of all malignancies and is the sixth most common malignancy worldwide. There will be an estimated 38,000 new cases and 11,000 deaths in the United States in 2004 and approximately 500,000 cases worldwide yearly [1]. Squamous cell carcinoma accounts for at least 95 percent of all head and neck cancers. Surgical treatment remains the standard of therapy for patients with resectable HNSCC. For patients with high risk of local or distant relapse, radiation therapy (RT) alone, or in combination with chemotherapy, is given after surgery to improve loco-regional control and overall survival.
Neoadjuvant chemotherapy for patients with respectable HNSCC remains an experimental option for these patients. A two-week delay in definitive surgical resection in patients with operable HNSCC is not thought to impact the clinical outcome of these patients and in many cases may be needed to complete all of the preoperative work-up. As a result, a study design involving a two-week preoperative course of therapy in patients with operable HNSCC should not be a concern.
EGFR as a therapeutic target in HNSCC
Epidermal growth factor receptor (EGFR) is a 170-Kda transmembrane protein that is thought to be important in the proliferation and survival of cancer cells [2]. Overexpression of EGFR has been found in several malignancies, including head and neck, lung, breast, prostate, bladder, and pancreatic cancer [3-7]. In HNSCC, EGFR and its ligand TGF are overexpressed in 80-90% of tumors compared to normal mucosa; [8] the coexpression of receptor and ligand implicates an autocrine regulatory pathway in HNSCC carcinogenesis. The clinical relevance of EGFR overexpression as an independent prognostic factor in HNSCC has been well demonstrated. High tumor EGFR levels are correlated with advanced stage,[9] increased tumor size, [9] decreased survival,[10-13] increased recurrence,[10] and decreased sensitivity to radiation treatment [14]. A recent study suggests that high serum EGFR levels may even correlate with higher head and neck tumor grade [15]. The overexpression of EGFR and ligand in partially and fully transformed HNSCC tissue, its correlation with poor clinical outcome, and the aberrant function of the EGFR network in HNSCC provide compelling evidence of a relationship between EGFR and the development and progression of HNSCC, and suggest a role for EGFR as a target for cancer therapy.
EGFR has been targeted at the extracellular domain by blocking ligand binding, at the intracellular domain by inhibiting tyrosine kinase activity, and at the genetic level by targeting production of the receptor itself. EGFR-specific monoclonal antibodies interfere with ligand binding, while conjugation of an EGFR ligand or antibody to a bacterially derived toxin enables the delivery of a cytotoxic agent to the cell surface. Many of the EGFR-targeting agents are undergoing clinical evaluation in HNSCC. In general, clinical responses in HNSCC patients with advanced disease have only been observed when these agents have been combined with cytotoxic chemotherapy or radiation therapy. Clinical trials using EGFR inhibitors as adjuvant therapy for HNSCC are currently underway.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Erlotinib and Erlotinib plus sulindac in people with Head and Neck Squamous Cell Carcinoma, run by University of Pittsburgh 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 12 inclusion and 17 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 28 Mar 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?
Phase II Study of TARCEVA (Erlotinib) as Adjuvant Treatment for Locally Advanced Head and Neck Squamous Cell Carcinoma with Evaluation of Neoadjuvant Biomarker Modulation with TARCEVA vs. TARCEVA Plus Sulindac (time frame: 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 28 Mar 2023.
