Résumé
Date de début de l'étude : 1 décembre 2004
Date à laquelle le premier participant a commencé l'étude.PRIMARY OBJECTIVES: I. To determine the biochemical response rate (> 75% decrease in P-MAPK and/or P-AKT) with daily oral OSI-774 (erlotinib) for 14 consecutive days in patients with early stage, operable NSCLC. SECONDARY OBJECTIVES: I. To evaluate the safety and tolerance of daily oral OSI-774 (erlotinib) as pre-operative treatment for early stage operable NSCLC. TERTIARY OBJECTIVES: I. To correlate antiproliferative (Ki-67, p27) and apoptotic (TUNEL assay) tumor responses to OSI-774 (erlotinib) with pre-therapy tumor and skin EGFR pathway functional status and post-therapy tumor and skin EGFR pathway inhibition in patients with resectable NSCLC treated preoperatively with OSI-774 (erlotinib) for 14 days. II. Assessment of functional EGFR status: HER1, HER-2, HER3, HER4, PHER1, AKT, P-AKT, MAPK-P-MAPK, STAT-3, P-STAT-3, EGFR-III by immunohistochemistry (IHC). III. Assessment of proliferative response: Ki67 and p27 by IHC. IV. Assessment of apoptotic response: TUNEL assay. V. To study the role of the gastrin-releasing factor and estrogen receptor pathways in the sensitivity and resistance of NSCLC to OSI-774 (erlotinib). VI. To identify patterns of gene and protein expression pre-therapy and post-therapy that are associated with tumor clinical, biochemical, antiproliferative, and apoptotic responses. VII. To study the antitumor activity of OSI-774 (erlotinib) in NSCLC tumors heterotransplanted in nude mice after surgical resection and to investigate the sequential molecular changes associated with tumor response to OSI-774 (erlotinib) therapy. OUTLINE: This is a multicenter study. Patients receive oral erlotinib once daily on days 1-14 or days 1-21 in the absence of unacceptable toxicity. Patients then undergo surgical resection on the last day of study drug administration (day 14 or day 21). Patients may receive chemotherapy and/or radiotherapy after surgical resection at the discretion of the primary physician. Patients are followed for 5 years after study registration.

Critères
Inclusion Criteria: * Patients with suspicion of lung cancer without distant metastases * Patients are scheduled to have a tissue diagnostic procedure within 3 to 5 days of pre-registration * Patients are willing to allow collection and submission of baseline and post-therapy tumor tissue, skin and blood samples for this study * Patients must have ECOG performance status of 0, 1, or 2 * Patients must have no psychological, familial, sociological, or geographic conditions that will interfere with medical follow-up and compliance with the study protocol * Patients must have no prior chemotherapy or radiation therapy or no prior anti- EGFR treatment exposure * Patients must be able to take oral medication and not have malabsorption syndrome, or prior gastrointestinal surgery that limits their absorption (i.e. requiring total parental nutrition) * Patients must not be using phenytoin, carbamazepine, barbiturates, rifampicin, phenobarbital, oxcarbazepine, rifapentine, St John's Wort, or any other CYP 3A4 enzyme-inducing agent; any use of these substances must be discontinued at least 2 weeks prior to registration * Patients must not be taking any anti-coagulants * Patients must not have been treated with a non-approved or investigational drug within 21 days prior to pre-registration; patients must not have serious underlying medical condition that would impair the ability of patient to receive the planned treatment * Patients with a known hypersensitivity to OSI-774 (erlotinib) are not eligible * Patients must have histologically confirmed NSCLC; cytologic specimens obtained by brushing, washing or needle aspiration of defined lesions will be acceptable * Patients must have stage IA (T1N0M0), stage IB (T2N0M0), stage IIA (T1N1M0), stage IIB (T2N1M0; T3N0-1M0), or stage IIIA (T1-3N2M0) disease * Patients with small cell component on histology specimen are not eligible * A paraffin-embedded cell block and 1-2 segments of frozen tissue demonstrating NSCLC and obtained during the diagnostic biopsy is available for submission * Patients must be considered operable candidates and disease must be considered resectable * Pregnant or breastfeeding women are excluded from the study because the agents used in this study may be teratogenic to a fetus or child and there is no information on the excretion of the agents or their metabolites into breast milk * All females of childbearing potential must have a blood test or urine study within 1 week, prior to registration to rule out pregnancy * Women of childbearing potential and sexually active males are strongly advised to use an accepted and effective method of contraception * WBC \>= 3500/mm\^3 * ANC \>= 1500/mm\^3 * Platelet count \>= 100,000/mm\^3 * Total bilirubin \< 1.5mg/dL * SGPT and SGOT \< 3 times institution's upper limit of normal * Serum creatinine \< 2mg/dl or creatinine clearance \>= 20 ml/min
