FLORHAM PARK, N.J., March 30, 2021 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a late clinical-stage biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal diseases, today reported financial results for the fourth quarter and full year ended December 31, 2020 and provided highlights of pipeline and business progress.

“During 2020 our teams made significant progress advancing the clinical development of vonoprazan and building the foundation to become a leader in the gastrointestinal space,” said Terrie Curran, President and Chief Executive Officer of Phathom. “Our accomplishments position Phathom for a catalyst-rich year in 2021, when we expect to share results from our pivotal Phase 3 trials in H. pylori infection and erosive esophagitis and expand our vonoprazan development program into non-erosive reflux disease (NERD). Building on our momentum from 2020, we are well-positioned financially and operationally to continue our efforts in bringing vonoprazan to the millions of underserved patients with acid-related disorders.”

Fourth Quarter 2020 and Recent Business Highlights:

  • Completed patient enrollment in pivotal Phase 3 trial for vonoprazan in erosive esophagitis (PHALCON-EE).
  • Completed patient enrollment in pivotal Phase 3 trial for vonoprazan in H. pylori infection (PHALCON-HP).
  • Announced the planned expansion of vonoprazan development program into NERD.
  • Completed a successful public offering of common stock with net proceeds of approximately $89 million to fund the clinical development of vonoprazan and for working capital and general corporate purposes, including pre-commercial activities.

  • Fourth quarter net loss for 2020 was $53.7 million, compared to $98.0 million for fourth quarter 2019.

  • Fourth quarter 2020 research and development expenses increased to $41.6 million compared to $12.7 million for fourth quarter 2019 as a result of higher clinical trial costs and personnel-related expenses related to the development of vonoprazan, including the acceleration of patient enrollment in the current quarter.
  • Fourth quarter 2020 general and administrative expenses increased to $10.8 million compared to $3.0 million for fourth quarter 2019 due to the ongoing buildout of administrative and commercial functions.

About Vonoprazan
Vonoprazan is an oral small molecule potassium-competitive acid blocker (P-CAB). P-CABs are a novel class of medicines that block acid secretion in the stomach. Vonoprazan has shown the potential to have rapid, potent, and durable anti-secretory effects as a single agent in the treatment of gastroesophageal reflux disease (GERD) and in combination with antibiotics for the treatment of Helicobacter pylori (H. pylori) infection. Phathom in-licensed the U.S., European, and Canadian rights to vonoprazan from Takeda, which completed 19 Phase 3 trials for vonoprazan and received marketing approval in Japan and numerous other countries in Asia and Latin America.

About PHALCON-EE
PHALCON-EE is a randomized, double-blind, two-phase, multicenter Phase 3 trial that has completed enrollment of patients with erosive esophagitis (EE) in the U.S. and Europe. The first phase of the trial is evaluating the efficacy and safety of vonoprazan 20 mg administered once-daily (QD) compared to lansoprazole 30 mg QD for the healing of EE for up to eight weeks. The second phase of the trial is evaluating the efficacy and safety of vonoprazan 10 mg QD and 20 mg QD compared to lansoprazole 15 mg QD for the maintenance of healing of EE for 24 weeks. Both phases are also evaluating heartburn symptoms.

About PHALCON-HP
PHALCON-HP is a randomized, multicenter, Phase 3 trial that has completed enrollment of patients with H. pylori infection in the U.S. and Europe. Participants are randomized 1:1:1 to one of three arms: vonoprazan 20 mg administered twice a day (BID) and amoxicillin 1g administered three times a day (TID); vonoprazan 20 mg BID, amoxicillin 1 g BID and clarithromycin 500 mg BID; and lansoprazole 30 mg BID, amoxicillin 1 g BID and clarithromycin 500 mg BID. Each treatment regimen is being administered for 14 days. PHALCON-HP is evaluating the percentage of patients with successful eradication of H. pylori infection.
