Clinical trials have recently become very complex, especially for small and medium biotech companies, due to increased costs and regulatory requirements. Between 2008 and 2019, the cost of clinical trials increased by around 100 percent. In a 2018 study, a central cluster of trials had estimated costs of $12.2 million to $33.1 million. The trials cost a median of $41,117 per patient and $3,562 per patient visit. (Clinical Leader)
