I'm back, with mets... anyone in the Dasatinib+Femara trial?

Unfortunately, ladies, I'm back after three sweet years NED.  I'm one of those who was "never" supposed to have a recurrence, and here I am with bone mets in four thoracic vertebras and both sides of my sacrum/ilium.  I just had a quick oophorectomy/hysterectomy last week to start altering my hormone environment, and pathology found ILC in my right ovary, too.  At least the ovary is out of there now, and the bone spots are all tiny as yet, I'm told.  

My CA 27.29 tumor marker hovered between 15-19 until last January.  It wasn't checked again until the end of September.  It was 90.  That's what tipped us off.

Here's my question: I am to start on an aromatase inhibitor this coming week.  My oncologist has offered to put me in a Phase II trial for Femara + Dasatinib.  Half will get Femara only, the other half will get both drugs.  Do any of you know anything about this newish drug?  My other choice is to go for Arimidex off-study.  She says it's a "philosophical decision" and she's fine either way.  What would you do?  I really need some counsel as I know nothing about being in studies. 

She also wanted to put me on Pristiq (the next generation of Effexor, a new drug) for hot flashes, and I tried it but just could not handle it.  I felt horrible and had about seven side effects, one of which was a really gloomy mood-- on an anti-depressant!  Go figure.  So I will be gutting out the hot flashes and mood swings, I guess.  But I guess that's a story for another thread.

God bless us, every one,
