Clinical Development
VeriStrat® Prospective Trial: PROSE
Randomized Proteomic Stratified Phase III Study of Second Line Erlotinib versus Chemotherapy in Patients with Inoperable Non-Small Cell Lung Cancer (NSCLC)
Objective: To evaluate the efficacy of treatment stratification using the VeriStrat test on the effect of erlotinib vs. chemotherapy in 2nd line therapy in patients with advanced stage NSCLC.
- Initiated March 2008
- Patients with inoperable NSCLC
- Primary endpoint: Overall Survival
- Secondary endpoint: Progression Free Survival, Overall Response Rate
- Italian multi-institutional study
- Principal Investigator: Dr. Vanesa Gregorc, Scientific Institute, University Hospital San Raffaele

Other Studies
A Phase II Selection Design of Pharmacodynamic Separation of Carboplatin/Paclitaxel/Erlotinib or Erlotinib Alone in Advanced Non-Small Cell Lung Cancer Patients with Performance Status 2 Selected by Serum Proteomics (SWOG S0709)
Objective: To evaluate the efficacy of a pharmacodynamic separation treatment regimen of first line NSCLC patients in a VeriStrat Good patient population.
- Initiated January 2008
- Primary endpoint: select a regimen (erlotinib ± carboplatin and paclitaxel) for testing in Phase III against Standard of Care, based on minimum median PFS for > 3 months
- Secondary endpoint: Response Rate in patents with measurable disease
- Principal investigators: Primo N. Lara, MD, UC Davis Cancer Center & Paul Hesketh, MD, St. Elizabeth’s Medical Center
