Brief Summary:
This study tests the combination of two targeted therapies,along with chemotherapy treatment in the treatment of pancreatic cancer.

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Drug: Gemcitabine Drug: Erlotinib Drug: Sorafenib Phase 2

Detailed Description:

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.

Other Names:
  • Nexavar
  • BAY 43-9006

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. 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)).

  2. 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.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically or cytologically confirmed pancreatic adenocarcinoma not amenable to curative treatment with surgery. Patients with locally advanced disease must have disease that extends outside the boundaries of a standard radiation port.
  • Measurable disease, as defined by Response Evaluation Criteria In Solid Tumors (RECIST). This requires 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 CT scan. Pleural effusions and ascites are not considered measurable lesions.
  • No prior cytotoxic chemotherapy for metastatic disease. Prior adjuvant chemotherapy is allowed, however at least 6 months must have elapsed from administration of the last dose of chemotherapy or radiotherapy.
  • No prior therapy with a VEGF, EGFR, or multi-targeted kinase inhibitor.
  • Age >18 years.
  • Life expectancy of greater than 3 months.
  • Eastern Cooperative Oncology Group performance status 0-1.
  • Normal organ and marrow function as defined below:

    • White blood cells (WBC) >3,000/µl
    • Absolute neutrophil count >1,500/µl
    • Platelets >100,000/µl
    • Total bilirubin ≤ 2.5 x institutional upper limit of normal (ULN)
    • Transaminases(SGOT/ SGPT)

      • without liver mets ≤ 2.5 x institutional ULN
      • with liver mets ≤ 5 x institutional ULN
    • International Normalized Ratio (INR)

      • patients not on warfarin ≤ 1.5
      • patients on warfarin ≤ 3

  • Patients who received prior radiation therapy must have a site of measurable disease that is not located within the prior radiation port.
  • Patients who are on warfarin anticoagulation are allowed to participate as long as they fit the following 3 criteria:

    • They are therapeutic on a stable warfarin dose
    • Their INR target range is no greater than 3
    • They are monitored with regular INR testing
  • Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment.
  • Women of childbearing potential and men must agree to use adequate contraception (barrier method birth control) prior to study entry and for the duration of study participation. Men should use adequate birth control for at least three months after the last administration of study drugs.
