Phase I/II Study of Chemoprevention With EGFR and COX-2 Inhibitor

21 de outubro de 2014 atualizado por: Dong Shin, Emory University

Phase I/II Study of Chemoprevention With Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitor Erlotinib (OSI-774, Tarceva) and Cyclooxygenase-2 (COX-2) Inhibitor (Celecoxib) in Premalignant Lesions of Head and Neck of Former Smokers

Evaluate effect on cells and patient response to study medications, assess side effects of these medications, and evaluate chemicals in cells that may tell how the drug works, before, and after receiving the study medications.

Descrição detalhada

The purpose of this study is to evaluate the effect on cells and patient response to study medications, assess the side effects of these medications, and to evaluate chemicals in the cells that may tell how the drug works, before, and after receiving the study medications.

Approximately 61 patients will participate at Emory Winship Cancer Institute and Emory Crawford W. Long Hospital in Atlanta, Georgia.

Medida de resultado
Descrição da medida
Prazo
Dose Escalation and Toxicity: Toxicities Including Grades 1 to 4
Prazo: 12 months from time of enrollment
Participants received a fixed dose of celecoxib 400 mg orally BID continuously for 6 months. Erlotinib was dose escalated at 3 dose levels of 50, 75, and 100 mg orally every day for 6 months. Dose escalation followed a standard 3+3 escalation design.
12 months from time of enrollment
Clinical Outcome: Documented Progression
Prazo: 12 months from time of enrollment
Response evaluation was based on pathologic examination of the degree of dysplasia observed and recorded by an expert head and neck pathologist. Pathologic complete response was defined as complete disappearance of dysplasia from the epithelium. Pathologic partial response was defined as improvement of dysplasia by at least one degree (i.e., severe dysplasia becomes moderate dysplasia). Pathologic minor response or stable disease was defined as minor focal improvement without change of degree of dysplasia (i.e., focal improvement from moderate to mild dysplasia with still moderate dysplasia overall) or no pathologic changes after treatment. Pathologic progressive disease was defined as worsening by at least one degree of dysplasia (i.e., mild to moderate dysplasia) or development of invasive cancer on or following treatment.
12 months from time of enrollment
Clinical Outcome: Progression to a Higher-grade Dysplasia or Carcinoma
Prazo: Up to 55 months from initiation of therapy. Median duration of follow-up was 36 months.
