Yes. In vitro (petri dish), this method appears effective; and we have a solid understanding of why it works.

In practice, this does not always translate to effective treatments in actual people. Further, this type of treatment is known to have risks and side effects, so we will likely not be able to give it to everyone as a preventative measure. Further, it is not clear how early in the disease's progression one would need to take such a drug to get a significant benefit.
