Patient case: 54-year-old female with non-small cell lung cancer; genetic feature: EGFR (D770N)

Clinical trial: Erlotinib Hydrochloride Before Surgery in Treating Patients With Stage III Non-Small Cell Lung Cancer

Summary: This phase II trial studies how well erlotinib hydrochloride works before surgery in treating patients with stage III non-small cell lung cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib hydrochloride before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Detailed description: PRIMARY OBJECTIVES:
  I. To estimate the rate of mediastinal nodal clearance and complete pathological response after neoadjuvant erlotinib (erlotinib hydrochloride) in patients with epidermal growth factor receptor (EGFR) mutated stage III non-small cell lung cancer (NSCLC).
  SECONDARY OBJECTIVES:
  I. To determine the progression free survival in patient population of EGFR mutated stage III NSCLC patients who are treated with neoadjuvant erlotinib therapy.
  II. To determine the overall survival. III. To estimate the overall response rate from neoadjuvant erlotinib. IV. To estimate the surgical resection rate. V. To evaluate the safety of neoadjuvant erlotinib.
  TERTIARY OBJECTIVES:
  I. To determine several molecular and cellular biomarkers in the tumors, the skin and the serum that are predictive of the efficacy of neoadjuvant erlotinib.
  OUTLINE:
  Patients receive erlotinib hydrochloride orally (PO) once daily (QD) for 2 months and then undergo thoracotomy.
  After completion of study treatment, patients are followed up at 30 days, every 3 months for 1 year, and then every 6 months for 5 years.

Eligibility: Inclusion Criteria:

  -  Ability to take oral medication
  -  Patient must sign study specific informed consent prior to study entry
  Exclusion Criteria:
  -  Pleural or pericardial effusion
  -  Pleural effusions allowed if one of the following conditions are met: 1) negative cytology after adequate sampling by thoracentesis 2) effusion seen on CT scan but not on chest x-ray and deemed too small to tap under CT or ultrasound guidance

  -  Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
  -  Ongoing or recent (=< 3 months) significant gastrointestinal bleeding
  -  Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
