Piper Jaffray analyst Christopher Raymond is incrementally positive on shares of Akebia Therapeutics after new nephrologist survey data indicated that Auryxia "has not just turned a corner, but is really on quite a roll, both in terms of the drug's perception and its market share dynamics." With the stock down 4% since before last month's merger announcement with Keryx (KERX), Raymond sees a "significant opportunity" to own Akebia before the drug's near-term share gains and the "real potential of a nephrology powerhouse with both Auryxia and vadadustat, become more apparent." He raised his price target for the shares to $22 from $20 and keeps an Overweight rating on the name.
