I believe since human bodies have not changed that a technology that worked 20 or even 50 years will work even better today than it did then because technology is better. So yes and it will prove that during trials no matter who refutes it.
Under normal circumstances, you're right about improvements in technology. One exception is pancreatic cancer, for which outcomes today are hardly better than they were 20 years ago. Lots of recent failures with potential treatments in this disease. It's an area of unmet need. That being said, PMCB has not shown that it has the ability or the finances to capitalize on this unmet need. I own shares but I realize it's a risky proposition.
