GLIOMARK is segmented into 10 work packages. WP1 contains all regulatory support for preparation/conduct of clinical phases II and III (pivotal validation study), including clinical trial application. WP2-4 cover the phase II, with all preparatory work including training of trial site staff and qualification of all trial sites (WP2), trial conduct (WP3) and analysis (WP4). WP5-7 contain the phase III validation study, with preparatory work including training of trial site staff and qualification of all trial sites (WP5), conduct (WP6) and analysis with subsequent publication (WP7). WP8 comprises establishment of a GMP process and GMP manufacturing. Furthermore, distinct work packages are dedicated to management & administration (WP9), as well as to communication & commercialization (WP10).

The concept of this project was based on the innovative research work by Dr. Andreas Fotopoulos (Professor of Nuclear Medicine, University of Ioannina and University Hospital of Ioannina) and his group over the last decade.

Within the project, 2 clinical studies will be performed. In a phase II study the evaluation of technical and diagnostic performance will be conducted. The study has been conducted successfully with all endpoints met with sites in Hungary and France. Data will be used to decide on optimum L/N cut-off value to be used in phase III study.

Subsequently, a pivotal phase III validation study will be conducted which is blinded, controlled, multi-centered and randomised across Europe. This study serves as the pivotal study for application for EU marketing authorisation with EU orphan designation. The relationship between TTF uptake as biomarker for BBB permeability and differential glioma diagnosis, as well as between TTF uptake and histologic glioma grading/aggressiveness will be formally proven. This study is planned, clinical centres are identified and contracted and essentially the study is ready to start.

proACTINA SA is a privately owned Small-Medium Enterprise (SME), founded in 2006 as a Contract Research Organization, in Athens-Greece. Currently the company is active in Life Sciences projects with main focus the development of novel diagnostic tools for gliomas (brain tumors). In addition, the company cooperates with Universities and Research Institutes throughout Europe, in the frames of collaborative research programs funded by either national or European sources (see here).

ProACTINA has been is responsible for production of tetrofosmin and lead all commercialization activities. It has the know-how of manufacturing the diagnostic product to be used in the clinical validation.
