LU 177 after docetaxel and radium 223?

[charliecar]

My husband has stage four prostate cancer that has progressed throughout his bones, Docetaxel did not work and his psa went up into the 90's. He is now on his second treatment of radium 223. We do not know, at this point, if it is working. My question is as follows: Is he still eligible for the Lu 177 trials/treatments even though he has gone through these 2 treatments? Thank you
