Hi Paul
I've had a similar experience, but been taken of the abiraterone much more quickly. I started the trial just under 4 weeks ago and a blood test after two weeks showed a rise in the ATS to around 90. This meant that I had to have another blood test the following week and as that showed ATS at over 200 I was told to come off the abi immediately, but continue with the enzo.
Last week I had a further blood test which showed the liver function returning to normal (down to 105) and was given a choice by my consultant - either go back onto a lower dose (750 rather than 1000mg) of abi, or come off abi altogether and continue with the ADT and enzo. Apparently this is an option for arm J.
I had no side effects on the two drugs together, in fact I have slightly more aches and pains now I'm back down to one (although that might be because of different exercise or a thousand and one other variables).
As my consultant explained, because of the new NICE guidelines I can't have both Abi and Enzo in the future, so coming off one now might be a blessing in disguise - I get the Enzo now, but as that's part of a trial I can have Abi at a point before or after chemo once the hormones stop working.
