As reported late last week, SunTrust analyst Peter Lawson downgraded NewLink Genetics (NLNK) to Hold from Buy and lowered his price target to $5 from $19. Lawson cites the announcement of negative results from the Phase 3 ECHO-301 of epacadostat + Keytruda in melanoma by Incyte (INCY), saying the data also implies a "significant negative read through for NewLink's IDO agent, indoximod". Lawson adds that the results have led him to remove melanoma from his NewLink model and also reduce the probability of success in pancreatic cancer, lowering the probability of adjusted peak sales from $415M to just $11M.
