Why Ardelyx Inc (ARDX) Shares Tumbled 30% Today

Ardelyx Inc (NASDAQ:ARDX) investors are having a rough day after the drug maker reported topline results from its T3MPO-1 trial, the first of two Phase 3 trials evaluating tenapanor for the treatment of patients with irritable bowel syndrome with constipation (IBS-C).

While the trial achieved statistical significance for the primary endpoint and seven of eight secondary endpoints, the results failed to beat out Synergy’s (NASDAQ:SGYP) drug plecanatide, which won FDA approval earlier this year.

As of this writing, shares of Ardelyx are falling over 30% to $8.30, while shares of Synergy are climbing nearly 5% to $4.07.

CEO Mike Raab commented, “We’re pleased to have achieved the primary endpoint in the T3MPO-1 trial. IBS-C is an extremely difficult, life-altering condition, and despite advancements, there remains a strong need for new, innovative treatments. In this trial, tenapanor demonstrated clinical activity across a large number of study parameters and had a favorable safety profile consistent with previous clinical experience. With a differentiated mechanism of action, we believe tenapanor has the potential to augment the care of patients with IBS-C.”

On the ratings front, Wedbush analyst David Nierengarten reiterated a Buy rating on ARDX, with a price target of $24, in a report issued on February 23. The current price target implies an upside of 200% from current levels. According to TipRanks.com, Nierengarten has a yearly average return of 28%, a 51% success rate, and is ranked #119 out of 4560 analysts.
