Clinical trial: Erlotinib Hydrochloride With or Without Carboplatin and Paclitaxel in Treating Patients With Stage III-IV Non-small Cell Lung Cancer

Summary: This randomized phase II trial studies how well erlotinib hydrochloride with or without carboplatin and paclitaxel works in treating patients with stage III-IV non-small cell lung cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving erlotinib hydrochloride together with carboplatin and paclitaxel may kill more tumor cells.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine the distribution of progression-free survival (PFS) in patients with previously untreated advanced adenocarcinoma of the lung who are never or light former smokers treated with either OSI-774 (erlotinib) (erlotinib hydrochloride) alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  SECONDARY OBJECTIVES:
  I. To determine the radiographic response rate in patients with previously untreated advanced adenocarcinoma of the lung who are never or light former smokers treated with either OSI-774 (erlotinib) alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  II. To determine the frequency of epidermal growth factor receptor (EGFR) and V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (K-ras) mutations and anaplastic lymphoma kinase (ALK) translocations in patients with previously untreated advanced adenocarcinoma of the lung who are never or light former smokers.
  III. To determine the response rate and time to progression in patients with and without EGFR mutations treated with either OSI-774 (erlotinib) alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  IV. To determine the response rate and time to progression in patients with and without K-ras mutations treated with either OSI-774 (erlotinib) alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  V. To determine the median and overall survival of patients with previously untreated advanced adenocarcinoma of the lung who are never or light former smokers treated with either OSI-774 (erlotinib) alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  VI. To estimate the response rate, progression-free, and overall survival of patients with echinoderm microtubule associated protein like (EML)4-ALK translocation who received OSI-774 erlotinib alone (arm A) or in combination with carboplatin/paclitaxel (arm B).
  OUTLINE: Patients are randomized to 1 of 2 treatment arms.
  ARM I: Patients receive erlotinib hydrochloride orally (PO) once daily (QD) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
  ARM II: Patients receive erlotinib hydrochloride as in Arm I. Patients also receive paclitaxel intravenously (IV) over 1-3 hours and carboplatin IV over 15-30 minutes on day 1. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. After completion of 6 cycles of treatment, patients may continue to receive erlotinib hydrochloride alone as above.
  After completion of study treatment, patients are followed at least every 3 months for 1 year and then every 6 months for up to 2 years.

Eligibility: Inclusion Criteria:
  -  Histologic documentation of primary lung adenocarcinoma including any variant thereof such as pure or mixed bronchioloalveolar carcinoma or adenosquamous cell carcinoma; patients with non-small cell lung cancer (NSCLC) not otherwise specified (NOS) are not eligible
  -  Pathology block or unstained slides from initial or subsequent diagnosis must be available for sequencing of EGFR, K-ras, Erb-2 and B-raf; patients need to have had at least a core biopsy; patients whose diagnosis was made through a fine needle aspirate will not have sufficient material for mutational analysis and are not eligible
  -  Select stage IIIB with cytologically documented malignant pleural or pericardial effusion OR stage IV disease
  -  Patients must be chemotherapy naïve; they may not have received neo-adjuvant or adjuvant chemotherapy
  -  No prior exposure to OSI-774 (erlotinib) or other treatments targeting the human epidermal growth factor receptor (HER) family axis (e.g., trastuzumab, gefitinib, cetuximab, lapatinib, etc.)
  -  No uncontrolled central nervous system metastases (i.e., any known central nervous system [CNS] lesion which is radiographically unstable, symptomatic and/or requiring corticosteroids); patients must be >= 3 weeks beyond completing cranial irradiation and off corticosteroid therapy
  -  >= 3 weeks since prior radiation therapy
  -  >= 3 weeks since prior major surgery
  -  No treatment with an investigational agent currently or within the last 28 days
  -  Non-smoker or former light smoker; non-smoker is defined as a person who smoked =< 100 cigarettes in their lifetime while a former light smoker is a patient who smoked between > 100 cigarettes AND =< 10 pack years AND quit >= 1 year ago; this must be documented on the On-study Form (C-1405)
  -  Eastern Cooperative Oncology Group (ECOG) 0 or 1
  -  Non-pregnant and non-nursing
  -  No dysphagia or active gastrointestinal disease or disorder that alters gastrointestinal motility or absorption; no lack of integrity of the gastrointestinal tract (e.g., a significant surgical resection of the stomach or small bowel); patients unable to swallow intact tablets must be able to swallow tablets dissolved in water
  -  Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral computed tomography (CT) scan; lesions that are considered non-measurable include the following:
  -  Bone lesions
  -  Leptomeningeal disease
  -  Ascites
  -  Pleural/pericardial effusion
  -  Lymphangitis cutis/pulmonis
  -  Abdominal masses that are not confirmed and followed by imaging techniques
  -  Cystic lesions
  -  Granulocyte >= 1,500/mcl
  -  Platelet count >= 100,000/mcl
  -  Hemoglobin >= 9.0 g/dL
  -  Total bilirubin =< upper limit of normal (ULN)
  -  Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) =< 2.5 x ULN
  -  Creatinine =< 1.5 mg/dl
