Abstract
Background:
With available funding from the public sector decreasing while medical needs and scientific complexity increase, private-sector collaborations with academia and government have become increasingly key in furthering medical innovation. Nonetheless, some skeptics diminish the contribution of the private sector to the discovery and development of truly innovative drugs on the one hand, while on the other hand they assert that research and development (R&D) of new medicines could and should be exclusively within control (at least financially) of the government. This begs the question, How much government funding would be needed to replace industry new drug R&D spending?
Methods:
We address the respective roles of the private and public sectors in drug development by examining a diverse array of evidentiary materials on the history of 19 individual drugs, 6 drug classes, and 1 drug combination identified as the most transformative drugs in health care over the past 25 years by a survey of over 200 physicians.
Results:
Only 4 of the individual drugs appear to have been almost completely researched and developed by one sector. One sector or the other, however, did dominate particular phases of the R&D continuum. For example, 54% of basic science milestones were achieved predominantly by the public sector and 27% by the private sector. For discovery milestones, it was 15% by the public sector and 58% by the private sector. The private sector was also dominant in achieving the major milestones for both the production and drug development phases (81% and 73% of the drugs reviewed, respectively). For 19% to 27% of the case histories for the various categories, dominance of one sector versus the other could not be determined. On the question of replacing industry’s spending on the R&D of medicines, we estimate quite conservatively that the amount that would have to be spent by government would be nearly double the budget of the National Institutes of Health just to maintain the flow of the most innovative drug approvals and would have to increase nearly 2.5 times that level to maintain the development of all new drugs.
Conclusions:
Our analysis indicates that industry’s contributions to the R&D of innovative drugs go beyond development and marketing and include basic and applied science, discovery technologies, and manufacturing protocols, and that without private investment in the applied sciences there would be no return on public investment in basic science.
