"Real question is what % of drugs are granted the OK for compassionate use."
And the answer is 99%:
"Yes, FDA approval may take a long time, but patients are able to access drugs (if the drug company permits) via compassionate use as soon as—or even before—the drug is first tried in humans. The FDA does a case-by-case review of all requests and approves more than 99 percent of them."
The "FDA granted compassionate use for brilacidin so they must believe it works" argument was always completely wrong, as has been highlighted here many times.
