The cost of doing business Background: The total cost of bringing a drug to market is highly debated, but the most reliable estimates seem to place the figure at around US$1 billion or higher. Instructions: Read the text below and use the information to answer questions in a subsequent unit. Learning Goal: To learn about the cost of the different stages of drug development. According to DiMasi et al.,1 the costs of a drug can be broken down as shown below.
Note that the pre‐clinical stages of drug discovery, which can take years, only account for approximately one quarter of the total costs. The expenses begin to accrue quickly with the clinical trials. Phase III typically costs the most because of the very large number of patients involved. In Phase I and Phase II, volunteers and patients are intensely monitored. The costs of Phase I and Phase II might be lower than Phase III, but the per patient costs are higher in the early phases. 1.
