Dr. Shaw has written a comprehensive article on all 10 ALK Inhibitors being developed as of July 7, 2014.
It provides comparisons of testing status, concentration levels, side effects and much more. It also includes a 2 page list of references.
As I have posted elsewhere, it currently looks like only 8 ALK inhibitors are continuing clinical trials. Astellas recently appears to have stopped work on ASP-3026 and Teva recently appears to have stopped work on CEP-37440.
