Hi Grifmat,
Promacta is not yet approved for AA - only for ITP and Hepatitis C.

In clinical trials AA patients have responded.

It is very good that your mother can try Promacta either because she perhaps has ITP or off record (I have been treated with Thalidomide off record since 2010).
Kind regards
Birgitta-A
