Details and patient eligibility

About

The purpose of the study is to evaluate a new treatment strategy for advanced pancreatic cancer disease by combining the new investigational medicinal product Atu027 with the standard chemotherapeutic gemcitabine. This combination aims at enhancing gemcitabine´s anti-tumor activity with Atu027.

The objectives of this clinical trial are to evaluate safety and activity of two Atu027 schedules in combination with standard gemcitabine treatment in patients with advanced or metastatic pancreatic adenocarcinoma.

• Life expectancy of at least 3 months
• No interstitial pneumonia or extensive and symptomatic interstitial fibrosis of the lung
