Sounds to me like the reporter (not surprisingly) oversimplified a complex issue. It is the case that ponatinib seems to be able to overcome all single-point mutations in CML (but not multiple mutations) and likely the reporter read about that and reported it as "block all mutations." Berger's actual quote is much more realistic.
I've very rarely read a newspaper article where I have actual knowledge of the facts reported in which I can't point to an error of some kind in the article.
