Until very recently, additional therapies in pancreatic cancer have targeted either the vascular endothelial growth factor (VEGF) or epidermal growth factor (EGF) pathways, a strategy which has shown variable clinical efficacy. This inconsistency is not surprising, given the knowledge that tumors have a certain level of signal redundancy which may limit the effectiveness of any one single-targeted therapy. The dual blockade of the EGF and VEGF pathways takes aim at two of the most active cascades in tumorigenesis. Preliminarily, a phase II study done in pancreatic cancer with gemcitabine, bevacizumab and erlotinib or cetuximab has shown promising results and will most likely proceed to phase III study for definitive efficacy assessment (Kindler et al, 2006).
In this study, targeted blockade is carried one step further with the inhibition of the signaling cascade downstream of receptor tyrosine kinases at the level of raf. Given the fact that the majority of pancreatic tumors display constitutive activation of the Ras/Raf/MEK/ERK pathway, it is hoped that the addition of sorafenib to gemcitabine and erlotinib will obtain a more complete blockade of the signal transduction cascade responsible for pancreatic tumor growth and progression.

Experimental: Combination GES
Combination of Gemcitabine, Erlotinib, and Sorafenib
1000 mg/m^2, intravenous, Days 1, 8, 15 for every 28-day cycle. In the absence of disease progression or toxicity, a patient may continue to receive gemcitabine, erlotinib, and sorafenib until disease progression.
Other Name: Gemzar
150 mg, taken orally, once a day, Days 1-28 for every 28-day cycle. In the absence of disease progression or toxicity, a patient may continue to receive gemcitabine, erlotinib, and sorafenib until disease progression.
400 mg, taken orally, twice a day, Days 1-28 for every 28-day cycle. In the absence of disease progression or toxicity, a patient may continue to receive gemcitabine, erlotinib, and sorafenib until disease progression.
- 4-month Progression Free Survival (PFS) Rate [ Time Frame: 4 months ]The PFS rate at 4 months is defined as the percentage of patients whose disease is progression free at 4 months from the start of treatment. Disease progression is evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) (Therasse et al, 2000). Radiological measurements to determine progression is performed every 2 cycles.
- Objective Response Rate [ Time Frame: up to 1 year ]The response rate is the percentage of the patients who have a complete response or partial response based on RECIST from the start of the treatment. The response is evaluated every 2 cycles by radiologic methods (e.g., computer tomography (CT)).
- Median Overall Survival (mOS) [ Time Frame: up to 2 years ]Median overall survival is defined as the time when 50% of the patients are alive from the start of the treatment.
