Correct. This is because regulations raise the barrier to entry for new drugs to $2.6 billion (in 2019 dollars) https://www.policymed.com/2014/12/a-tough-road-cost-to-devel...

Obviously, some amount of testing is necessary to bring a new drug to market (and the examples you point out support this). If there is no alternative but suffering and death for a condition, having these blanket regulations in place that block new drugs and new treatments only contributes to suffering.
