Pancreatic Cancer
Conditions
Brief summary
The purpose of the study is to determine the optimal safe and tolerable dose of gemcitabine in combination with once daily or twice daily dose of PTK/ZK in patients with unresectable pancreatic cancer. The Phase II part of this study planned to determine the antitumor activity of this regimen and its effectiveness of preventing tumor growth and spread.
Interventions

Population: Evaluable subset of subjects that terminated from the study due to disease progression (endpoint).~No participants were analyzed in the Stage 1 Dose Exploration 2 - Gemcitabine 850 + Vatalanib 2 x 250 / 2 x 500 group because no evaluable participants progressed within 12 months.
