I see you have tried abiraterone. Based on what I've learnt, Lu177 (Pluvicto) may be promising if all of your metastases show uptake on PSMA PET. Others include docetaxel or enzalutamide (or another 2nd generation antiandrogen). If feasible, consider getting a gene mutation test to guide future treatments. If you're not yet receiving care at a major cancer center, it might be time to consider that as treatment becomes more specialized after the first/second line therapies. Good luck!
