Piper Jaffray analyst Tyler Van Buren reiterates an Overweight rating and $200 price target for Loxo Oncology (LOXO) after the company provided an update of the thyroid patients in the Phase I/II study of LOXO-292. The analyst highlights that in the largest patient population the response rate increased from 45% to 59% with three additional patients responding between 9 and 12 months. Blueprint Medicines' (BPMC) competing BLU-667 reported a 49% ORR in a similar patient population and recall that adverse events of hypertension are still a concern, he notes. Van Buren believes that the 667's safety profile could continue to look worse as it continues to administer the drug to patients at higher doses and that treatment discontinuations could increase. Overall, the analyst believes Loxo's 292 appears to be the superior RET inhibitor in development, both in terms of efficacy and safety and could easily become a $1B+ drug.
