It's a drug trial,
With PSA rising (doubling about every 5 weeks) my husband was offered Abiraterone or Enzalutmide or to look at trials, We went to the Marsden and it was suggested a trial with Abiraterone plus either the trial drug or a placebo. This trial drug is Ipatasertib it's a double blind so only half the people will be on it. Lots of testing and checking and scans. So far it has reduced PSA and having scans done this week so will find out more next week. Minimal side effects. This trial is world wide. Many different countries are taking part.
There are lots of different drugs being trialled.
