ABT-263 experimental drug or feasible solution in the near future?

Hi.

Just stumbled across this article. Published a while back but just recently made available online.

I know it is still about saving mice ;), but it is indeed interesting given the preliminary results.

However I can´t really distill whether ABT263 is an existing drug developed for other purposes (http://www.selleckchem.com/products/ABT-263.html), if it is experimental but in human trials or if its experimental and to this point only applied to xenographs.

Any views/perspectives on the application of ABT-263?
