Study information
Scientific title
A prospective, non-randomised phase II study of trastuzumab and capecitabine in patients with HER2 expressing advanced pancreatic cancer
Acronym
Study hypothesis
Pancreatic cancer is the fourth most common cause of cancer related death in Western countries. Advantages in surgical techniques, radiation and chemotherapy had almost no impact on the long term survival of affected patients. Therefore, the need for better treatment strategies is urgent. HER2, a receptor tyrosin kinase of the epidermal growth factor receptor (EGFR) family, involved in signal transduction pathways leading to cell growth and differentiation is overexpressed in a number of cancers, including breast and pancreatic cancer. While in breast cancer HER2 has already been successfully used as a treatment target, there are no studies thus far evaluating the effects of inhibiting HER2 tyrosine kinases in patients with pancreatic cancer.
Ethics approval
Ethics approval received from the Ethics Committee of the University of Freiburg, Germany on the 19th April 2004.

Condition
Advanced pancreatic cancer (stage IVb)
Intervention
The trastuzumab loading dose of 4 mg/kg body weight will be given on day one over 90 minutes. For maintenance therapy a weekly dose of 2 mg/kg body weight over 30 minutes will be infused until tumour progression takes place. Patients will be monitored closely for six hours during the first dose of trastuzumab and for two hours after the following rastuzumab infusions to rule out adverse reactions.
Capecitabine will be applied orally twice daily at a dose of 1250 mg/m^2 on day 1 - 14 followed by a break of seven days. The three weeks cycles will be repeated until tumour progression or until a grade three to four toxicity occurs.
Planned duration of treatment 12 weeks or until disease progression. In the case of stable disease treatment is continued until progression. Follow up is performed until death.
