Clodronate therapy, I'm not sure if you know this, but looks very interesting

I was searching the internet for something else and I've found this interesting site. It is not for me (I'm from uterine cancer board) but I thought maybe can help some of you.
It is about a drug clodronate, nothing new, popular in Europe and not approved by FDA but still maybe someone want to read it.
