Help to look for treatment or a trial for ER positive, HER2 negative in bone and brain.

Clinicaltrials.gov might be a good place to start. It’s a US site but lists worldwide trials, Cancer Research has details of all current clinical trials in the Uk. I realise you have said outside the UK but I mention this as phase 3 trials are usually done globally. So if you can identify a trial of interest, you might be able to find out if it is also active where you are. 

Thank so much for this - I'll look into it straight way.
