The researchers can always come up with another research project. A large scale study is to examine adherence and non-adherence with MS therapies. Now I'm not a scientist, and I must have lost a few brain cells to this disease, but my wild guess for non-adherence could be that people don't like sticking needles into themselves with drugs that have horrible side effects and have limited efficacy. Of course I might be wrong, so X,000 researchers and $X,000,000 might find different reasons. Now, if they came up with a once a day tablet, with no side effects, which stopped this disease in its tracks, then non-adherence might not be a problem. But then there'd be no more work for the researchers! And Biogen want us to be adherent as it means we're using their drugs to the fullest possible extent - which of course means more revenue!
