Content - Clinical trials
Clinical cancer research in patients is quite distinct from basic research, in which disease processes are investigated in the laboratory and research is carried out for new active substances. In these preclinical studies, new medicines are tested in cell lines and animals to determine their efficacy, safety and dose. Only when these studies have been successfully completed can clinical studies be started. Clinical studies are carried out by pharmaceutical companies, contract research institutes, cooperative groups and state institutions. The study directors are responsible for the planning and implementation of the studies. In Switzerland, the studies are financed by industry, the federal government, the cantons, hospitals, research funds, foundations and private sponsors.
