Higher-than-expected serum bicarbonate values in the placebo group foiled Tricida Inc.’s effort in its phase III renal outcomes trial to compare an untreated acidotic chronic kidney disease (CKD) population with those given veverimer. The hitch meant the company could not measure the oral, non-absorbed polymer’s ability to slow the disease in patients with metabolic acidosis, an estimated market of several million people in the U.S.
Shares in Ardelyx Inc. have crashed after its tenapanor, under FDA review for managing phosphate levels in chronic kidney disease (CKD), ran into trouble with the regulator. The company said that the FDA has identified “deficiencies” in the data package, which prevent discussions about labeling and postmarketing commitments.
A failure of Tricida Inc.'s most recent efforts to overcome FDA objections to an NDA for the company's sole candidate, veverimer, for treating metabolic acidosis, sent company shares (NASDAQ:TCDA) 30.6% lower to $5.11 on Feb. 26. The complex story appears focused now on the agency's desire for additional and more reliable data to support a potential approval. Tricida President and CEO Gerrit Klaerner on Thursday suggested the ongoing renal outcomes study, Valor-CKD, might provide it.
Tricida Inc. executives were not surprised when the FDA issued a complete response letter for veverimer to treat chronic metabolic acidosis.

With an Aug. 22 PDUFA date set, Tricida Inc. said it received an FDA notification regarding the NDA for veverimer (TRC-101) for treating metabolic acidosis in chronic kidney disease (CKD) patients, noting that it had identified deficiencies precluding discussion of labeling and postmarketing requirements/commitments.
