Brief Summary in Lay Language

A therapy for advanced pancreas carcinoma by surgical removal which is the cure for early stages is not possible. Chemotherapy and radiation therapy had only small success rates.
During the last few years a few drugs have been whic had an effect in different malignant tumors.
The new substance capecitabine is converted into the effective drug in tumor tissue. The conversion into the effective drug at the location of the tumor helps to minimize toxicities and side effects concerning other organs. Capecitabine can be applied orally in tablet form. Therefore venous port systems and intravenou infusions are not necessary. A therapeutic response for Capecitabine has been observed for patients with pancreas carcinoma.
A second new medication Trastuzumab has a specific effect on tumor cells, which have a specific protein (HER2/neu) in large quantities on their surface. Trastuzumab is an antibody, which is directed against the target structure (HER2) and slows down tumor growth. Up to 30% of all pancreas carcinomas carry a sufficient amount of this target proptein. The presence of the target will be assessed by tissue biopsy festgestellt. The medication will be applied once a week by infusion.Preliminary studies for pancrea carcinoma with a combination of Trastuzumab and other Chemotherapies a response.
This study was designed to find outif the combination of capecitabin and Trastuzumab in comparison with established chemotherapies shows a better response i. e. improves survival time and quality of life.

Brief Summary in Scientific Language

A generall accepted standard-chemotherapy for advanced pancreas carcinoma does not exist. Therapy of advanced, inoperable pancreas carzinoma is still of palliative character. Therefore it is the goal of any therapy to achieve an improvement of survival time with optimal quality of life.
The specific mechanism of capecitabine (Xeloda®) by accumulation and activation in tumor tissue and the Inhibition of HER2 receptor mediated tumor cell proliferation by Trastuzumab (Herceptin®) can improve the prognosis of HER2 positive pancreas carcinoma. Because of differentv mechanisms there are no overlapping toxicities. The side effects are all known, managable and reversible. The therapy can be applied on an outpatient basis and fullfills the needs of a patient for a minimum of stays in the hospital. Because of the pharmacocinetic similarities and the advantages of oral capecitabine versus continuous infusion of 5-FU it appears to be in the interest of improvement of palliative therapies for pancreas carcinoma patients to design combination protocols of Capecitabine with Trastuzumab. Clinical data for this combination are not yet available for the pancreas carcinoma.
In this multicenter phase-II-study the combinationen of Capecitabin/Trastuzumab should be assessed for efficacy and toxicity for the therapy of advanced , inoperable pancreas carcinoma.
