The CTCL Platform • Reasons for failure: - Complicated study design for the maintanance study - Prolongation due to regulatory affairs - Drug development was stopped - No aggreement within the BMT group on one protocol Arguments for EORTC studies in cooperation with academic medicine and industry EORTC as a label for independance and reputation in clinical research EORTC infrastructure with specialized and experienced expert in clinical studies EORTC as a clinical integrative research platform for Pan- European medicine EORTC as a strong inter-disciplinary network in oncology Problems for EORTC studies in cooperation with academic medicine and industry New drug developments are performed by pharmaceutical companies under their control and leadership: Data ownership Companies do not recognize the additional value of being asscociated with EORTC Clinical research is financed directly by clinical studies provided by pharma industry Individual centers have a higher profit margin EORTC‘s reputation is of controversial value Problems for EORTC studies in cooperation with academic medicine and industry How to solve the problems - Establishing a clinical study group - Defining new targets for therapy based on translational research - Involvement in early drug development - Performing small and effective Phase I and II studies - Performing studies in a given time frame - Fund raising Nature Review 2014 Nature Review 2014 Stage I II III CD4+ IV CD4+ CD8+ New target structures CD8+ Receptors eg.
