Number of companies dedicated to biotechnology: 570 (incl. 13 start ups) • Number of employees in dedicated biotechnology companies 16.950 • Over 90 drugs in clinical trial testing • R&D expenditure of dedicated biotechnology companies 899 Mio.€ • The German Biotechnology Sector 2014 source: Report: The German Biotechnology Sector 2014, biotechnologie.de
10-15 years for a drug to travel from the research lab to the patient. • 1 to 3 billion euros is the cost of a new drug development from the research lab to the patient • 1 in 10 000 active substances tested in research lab will be placed on the market • Drug development process source: Report: The German Biotechnology Sector 2014, biotechnologie.de

Phase I clinical trial Primary goal: safety & tolerabilty (20-80 subjects, weeks to months) • Clinical Trial Overview First in class First in man I a: safety & tolerability [single dose, healthy subjects] I b: safety & tolerability [multiple doses, healthy subjects] I c: safety & tolerability [single dose, patients] • Phase II clinical trial • Primary goal: efficacy & safety (30 -200 patients, months to years) First in class II a: explorative POC study [multiple dose, patients] II b. Proof of concept study [multiple ascending dose, patients] • The number and design of clinical trials may vary depending on country and regulatory agency

Scientific publications • Conference presentations & posters • Reports from preclinical and toxicological studies a including raw data • Documents submitted to regulatory agencies: Investigator´s Brochure (IB), clinical trial protocol, Investigational Medical Product Dossier (IMPD) • Audit reports of the external collaborators • SOP (Standard Operating Procedure) process overview • Evaluation criteria
The goal & destination of academic spin-off should be defined at the beginning based on: human resources, financial status, potential of research facility • Interaction with business partners is inscribed in the nature of academic spin-off • Therefore, quality standards required by business partners have to be fullfilled (or exceeded!) in order to ensure collaboration and secure seed financing • Meeting quality standards in practice means that the structure of academic spin-off should be carefully designed (professional writer & quality control, GLP) • Summary
