Searching clinicaltrials.gov with intrathecal and trastuzumab as search key provided this as the only link to stateside trial.
Don't know how much "anecdotal" data from this evaluation has been published, if any, I hope that it was all positive.
Details of trial and contact particulars can be found at:

Hope this little bit of info was helpful.
