Chapter 925 Brainwashing

New drugs, especially those that are particularly effective in treating tumors, tend to be extremely expensive, and there's no way around it because the research and development costs for new drugs are exceedingly high. Pharmaceutical companies invest vast sums in the R&D of new drugs, and the risks are also extremely high.

In the pharmaceutical industry, there's a "rule of thirty" regarding the R&D of new drugs: on average, it takes 10 years, costs 1 billion US dollars, and the success rate is less than 10%.

Take, for instance, the investments in the development of the latest cancer and immune drugs. Someone has calculated that, among 20 new drug samples, the average investment amounts to a staggering 4.46 billion US dollars.
