Stifel analyst Stephen Willey said the incremental follow-up data from Loxo Oncology's (LOXO) LIBRETTO-001 trial isn't "transformational," but it does confirm his confidence in the establishment of a high competitive hurdle for LOXO-292, which he sees being a "best-in-class" and first-to-market asset in a $1B+ market. He remains confident LOXO-292 is the superior asset, but acknowledges the anticipation of Blueprint Medicines' (BPMC) updated BLU-667 data at some point in late-FY18 to early-FY19 could serve as a bit of headwind on Loxo shares nearer to that data release. Willey keeps a Buy rating and $217 price target on Loxo shares.
