Summary
Brief summary (as posted)
This is a single-arm, open-label, multicenter, international pilot study to evaluate changes that occur in 2-deoxy-2-\[18F\]fluoro-D-glucose (FDG)- and 3'-deoxy-3'-\[18F\]fluorothymidine(FLT)-PET (Positron Emission Tomography) imaging as a result of treatment with erlotinib in patients with recurrent or refractory non-small cell lung cancer (NSCLC). The study will enroll approximately 30 patients at approximately 4 sites in Australia and 2 sites in the United States.

Arms (1)
- type
- EXPERIMENTAL
- label
- Erlotinib
- description
- Erlotinib 150 mg/day taken orally at approximately the same time of day with 200 mL (6-8 Ounces) of water on an empty stomach. Participants received Erlotinib for 1 year or until they developed progressive disease or intolerable toxicity. After 14 days and after 56 days of treatment with Erlotinib participants underwent FDG-PET and FLT-PET scans.

- Other: 3'-deoxy-3'-[18F]fluorothymidine (FLT)
- Drug: erlotinib HCl
Primary outcomes (8)
- measure
- Progression Free Survival (PFS) of Groups by FDG Response at Day 56
- timeFrame
- Time from first erlotinib treatment to disease progression on CT (per RECIST 1.0) or death, whichever occurs first, assessed up to 2 years
- description
- PFS was defined as the time from the date of first erlotinib dose to disease progression or death, whichever occurs first. PFS was compared between patients with FDG-PET response and patients without FDG-PET response, independent of CT response (per RECIST 1.0) at Day 56 of treatment with erlotinib. Mean of the percent changes in maximal standard uptake values (mSUVmax) from FDG-PET scans was used to define FDG-PET response. Based on European Organization for Research on the Treatment of Cancer (EORTC) definitions, an objective FDG-PET response was defined an mSUVmax \<-25%.

Inclusion Criteria: * Signed Informed Consent Form(s) * Histologically confirmed NSCLC * Recurrent or progressive disease after receiving at least one chemotherapy regimen for advanced or metastatic NSCLC * Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2 * Age ≥ 18 years * Recovery from reversible acute effects of prior anti-cancer therapy (chemotherapy, radiotherapy, or investigational treatment) to NCI Common Toxicity Criteria for Adverse Events (NCI CTCAE) Grade ≤ 1 (excluding alopecia) * Ability to comply with the study and follow-up procedures, including all specified imaging studies * Ability to take oral medication * Availability of archival diagnostic paraffin-embedded tumor tissue and willingness to provide sufficient tissue for testing for EGFR levels in tumor by both immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) * Life expectancy ≥ 3 months * Measurable disease on computed tomography (CT) * At least one detectable lesion on FDG-PET scan and/or FLT-PET scan that is measurable on CT * Use of an acceptable means of contraception (men and women of childbearing potential) or documentation of infertility Exclusion Criteria: * Prior treatment with an investigational or marketed agent for the purpose of inhibiting epidermal growth factor receptor (EGFR) (including, but not limited to, erlotinib and gefitinib) * Chemotherapy, radiotherapy, or investigational treatment within 14 days or within 5 half-lives of the active molecules in the chemotherapy or investigational treatment, whichever is longer, prior to study entry or from which patients have not yet recovered * Inability to take oral medications, disease affecting gastrointestinal absorption, or prior surgical procedure affecting gastrointestinal absorption * Uncontrolled diabetes * Any unstable systemic disease (including active infection, unstable angina, congestive heart failure, myocardial infarction within 1 month prior to study entry, hepatic, renal, or metabolic disease) * Pregnancy or lactation * History of another malignancy in the past 2 years, unless the malignancy has been adequately treated, is currently not detectable, and is associated with a 5-year survival \> 90% * Claustrophobia * Any other disease, condition, physical examination finding, or clinical laboratory finding which, in the opinion of the investigator, makes the patient inappropriate for the study
