This is true. There is only so long you can target anti-androgens (as abiraterone does) before it causes a whole heap of weird side effects. 201 in theory may bypass many of these issues, but as always, poking a new end of biology does occasionally have unintended consequences. In theory, I suspect we already know the consequences, as 201 is operating very similarly to existing medication, just on the very specific area.
Old 'best in class theory': Block all androgens - dozens of complications, side effects. Feedback mechanisms build up over the long term and create havoc in many body processes, in order to prevent hormone-induced tumour growth. Eventually this stops working. Common side effects: diarrhoea, high blood pressure, hypokalemia,urinary infections, sepsis, heart failure, rashes, weak bones, etc etc.
New potential '201 best in class theory' Leave androgens alone unless they try to drive hormone-induced tumour growth. No known side effects? May work eternally? (assuming non-mutated core DNA).
