Phathom Pharmaceuticals Inc. will begin marketing Voquezna (vonoprazan) in December, thanks to the Nov. 1 approval by U.S. regulators, who cleared the potassium-competitive acid blocker at 10-mg and 20-mg doses for all grades of erosive gastroesophageal reflux disease (GERD), maintenance of healing of all grades of the condition and relief of associated heartburn.
Phathom Pharmaceuticals Inc. made recent headway with its new mechanism of action in gastroesophageal reflux disease (GERD) even as further, disturbing discoveries in the space are seeing daylight. Florham Park, N.J.-based Phathom turned over to the U.S. FDA the requested six-month stability data related to reformulated vonoprazan tablets, and the numbers remained consistent with three-month data, reflecting N-nitroso-vonoprazan nitrosamine control and levels comfortably more than tenfold below the acceptable daily intake limit.
Phathom Pharmaceuticals Inc.’s shares sank 31% on news that the U.S. FDA will not take action on the company’s NDA for oral small-molecule potassium-competitive acid blocker vonoprazan by the Jan. 11 PDUFA date.
Thanks to positive phase III data from Phathom Pharmaceuticals Inc.’s Phalcon-EE study of patients with erosive esophagitis, the company is prepping to file an NDA with the FDA for its lead compound, vonoprazan.
With phase III data due from Phathom Pharmaceuticals Inc. in the near term, investor eyes are turning to the ways that lead compound vonoprazan, a potassium-competitive acid blocker, might distinguish itself from proton pump inhibitors (PPIs) in gastroesophageal reflux disease (GERD).
