Failure of a Multi-Centric Clinical Trial Investigating Neoadjuvant Radio-Chemotherapy in Resectable Pancreatic Carcinoma (NEOPA-NCT01900327)-Which Lessons Are Learnt?

Abstract

A significant number of clinical trials must be prematurely discontinued due to recruitment failure, and only a small fraction publish results and a failure analysis. Based on our experience on conducting the NEOPA trial on neoadjuvant radiochemotherapy for resectable and borderline resectable pancreatic carcinoma (NCT01900327-funded by the German Federal Ministry of Education and Research-BMBF), we performed an analysis of potential reasons for recruitment failure and general problems in conducting clinical trials in Germany. Systematic analysis of environmental factors, trial history, conducting and funding in the background of the published literature. The recruitment failure was based on various study-specific conceptional and local environmental aspects and in peculiarities of the German surgical study culture. General reservations against a neo-adjuvant study concept combined with game changing scientific progresses during the long-lasting planning and funding phase have led to a reduced interest in the trial design and recruitment. Trial planning and conducting should be focused, professionalized and financed on a national basis. Individual interests must be subordinated to reach the goal to perform more relevant and successful clinical trials in Germany. Bureaucratic processes must be further fastened between a trial idea and the start of a study.
