clinical trials costs are largely driven by labor, much of these savings are from lower salaries to physicians, nurses, and trial coordinators. It is true that some regions of the globe are vastly more expensive than others to conduct clinical trials. For example, a clinical trial in India can cost one-tenth of the price that it would cost in the US. However, the Risk of low quality in the other countries could be a pitfall for your clinical trials. I think clinical trials should not be about running inexpensive trial sites to benefit distant people, but should focus the quality and the results more than the cost!
