Thoughts on Krystal Biotech, Inc. (KRYS)?

I am big into biotech (as an interest, not a representation of my portfolio), and have been looking into what would make a biotech company a good position. I have been looking into Krystal Biotech, Inc. (KRYS), and a lot about their international growth along with the nature of their unique, orphan therapies make it look somewhat promising given U.S. regulations (orphan drug exclusivity). I don't wan't anyone to invest just based on my shallow analysis, but I wan't people's thoughts or general advice as to equity research specifically for biotech (small to mid-cap) companies.
