Name of the Trial

Pilot Study of Erlotinib in Patients with Stage IIIB or IV or Recurrent Non-Small Cell Lung Cancer (ECOG-E3503). See the protocol summary.

Principal Investigators

Dr. Julie Brahmer and Dr. Anne Traynor of the Eastern Cooperative Oncology Group.

Why This Trial Is Important

Lung cancer is the leading cause of cancer deaths in the United States. Several drugs developed recently to treat patients with non-small cell lung cancer (NSCLC) have targeted a receptor protein called epidermal growth factor receptor (EGFR). EGFR, which is found in abundance on some cancer cells, can promote cancer cell growth, survival, and metastases.

Erlotinib (Tarceva) is one drug that targets EGFR. Already approved by the FDA as a second-line treatment for advanced NSCLC, erlotinib has been proven in clinical studies to extend the lives of some, but not all, patients with advanced NSCLC. In this study, researchers hope to identify tumor characteristics associated with responses to erlotinib treatment. The study will also test erlotinib as a first-line treatment for advanced NSCLC.

"In past trials, researchers noticed that patients who developed a rash in response to erlotinib experienced prolonged survival," said Dr. Brahmer. "In this trial, we are also escalating the doses so that most, if not all, patients will develop a rash, and then we can see if that equates to an improvement in survival.

"With this trial, we hope to learn how to predict who will benefit from erlotinib as first-line therapy," Dr. Brahmer said.
