I was in the 2021-22 Pluvicto clinical trial in the US. At that time, and I believe this is still the case, Pluvicto was shown to "extend life 11 to 15 months".
It knocked my cancer back for 22 months. I then received ARC targeted beam on three troublesome tumors. That helped for a few more months. I was then selected to repeat the full 6 Pluvicto treatments starting in the fall of 2024. After 4 of the repeat 6 treatments, it again has greatly reduced the cancer, related tumors, etc. and I am doing great. So good, the last 2 treatments have been paused for the last 4 months. I will receive the remaining 2 when needed, hopefully not before mid 2026.
So, to summarize my response to a couple of questions, 11 to 15 months and I am a lucky patient who has responded extremely positively and doing as well as most any Pluvicto patient.
Good luck, do your research.
