Phathom Pharmaceuticals Reports First Quarter 2023 Results

FLORHAM PARK, N.J., May 10, 2023 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal diseases, today reported financial results for the first quarter of 2023 and provided updates on recent regulatory progress.

“This quarter, we made remarkable progress advancing mission-critical priorities that position Phathom to potentially deliver vonoprazan to patients suffering from Erosive GERD and H. pylori infection before year end,” said Terrie Curran, President and Chief Executive Officer of Phathom. “Our ongoing stability program for the minor drug product reformulation continues to demonstrate effective control of the N-nitroso-vonoprazan (NVP) impurity and confirms our confidence that our planned NDA resubmission will address the sole deficiency cited in the FDA’s complete response letters. Building on this positive momentum, our commercial team continues to prepare for a planned fourth quarter commercial launch and we remain engaged with payers, healthcare providers, and key opinion leaders to capitalize on the blockbuster potential of our first-in-class therapy.”

Clinical, Regulatory, and Business Updates:

  • Phathom remains on track to resubmit its erosive esophagitis (Erosive GERD) NDA this quarter, with potential for FDA approval and a subsequent U.S. commercial launch for Erosive GERD and H. pylori infection anticipated in the fourth quarter of 2023. The Company’s ongoing stability program for the minor reformulation of vonoprazan drug product continues to demonstrate that it is achieving the intended effects of limiting and controlling NVP formation. Based on FDA feedback from the March 2023 meeting, Phathom believes the data package it expects to include in the resubmission will address the NVP issue, the sole deficiency noted in the FDA’s complete response letters (CRLs).

  • In January 2023, Phathom shared positive topline results from the Phase 3 PHALCON-NERD-301 trial evaluating the daily dosing of vonoprazan for Non-Erosive GERD. Both vonoprazan 10 mg and 20 mg doses met the primary endpoint and showed highly statistically significant greater percentage of 24-hour heartburn free days as compared to placebo (p<0.0001). The blinded 20-week long-term extension period of the trial is proceeding as planned and a regulatory submission is expected for the second half of 2023 seeking approval of vonoprazan as a daily (QD) treatment for Non-Erosive GERD, the largest subcategory of GERD with an estimated U.S. patient population of over 45 million people.

  • Phathom has currently secured coverage for 60% of commercial lives for first-in-class H. pylori infection treatments VOQUEZNA® TRIPLE PAK® and VOQUEZNA® DUAL PAK®.

  • New data from two post-hoc analyses were presented in poster presentations during Digestive Disease Week® (DDW) 2023, held May 6-9 in person in Chicago, IL and virtually:

    • Higher eradication rates of H. pylori infection were demonstrated with vonoprazan-based regimens vs. lansoprazole triple therapy, regardless of different baseline demographics and clinical characteristics.
    • A meta-analysis showed that potassium-competitor acid blockers (PCABs), including vonoprazan, provide a longer duration of pH >4, higher predicted Erosive GERD healing rates, and lower probabilities of failure to achieve healing, as compared to histamine2–receptor antagonists (H2RAs) and proton pump inhibitors (PPIs).

First Quarter 2023 Financial Results:

  • Net loss for the first quarter ended March 31, 2023 was $37.8 million, compared to $40.7 million for first quarter 2022. First quarter 2023 net loss included a non-cash charge related to stock-based compensation of $7.0 million compared to $5.8 million for first quarter 2022.

  • Operating expenses for the first quarter 2023 were 36% lower than the preceding quarter, primarily due to cost control measures enacted as a result of the delayed commercial launch of VOQUEZNA TRIPLE PAK and DUAL PAK for H. pylori infection, and, if approved, VOQUEZNA for Erosive GERD.

  • Research and development expenses for the first quarter 2023 were $11.5 million, a decrease of $6.2 million compared to $17.7 million for first quarter 2022. The decrease was a result of decreased clinical trial costs and chemistry, manufacturing and controls costs, partially offset by increased personnel costs.

  • General and administrative expenses for the first quarter 2023 were $18.6 million, a decrease of $1.6 million compared to $20.2 million for first quarter 2022. The decrease was primarily due to a reduction in professional services partially offset by increased personnel costs.

  • As of March 31, 2023, cash and cash equivalents were $129.6 million. An additional $100.0 million is available under Phathom’s term loan with Hercules Capital and $175.0 million becomes available to Phathom upon FDA approval of VOQUEZNA for Erosive GERD under the terms of our revenue interest financing agreement.

  • Based on its current operating plan, including the funds currently available under our existing term loan and cash available under our royalty interest financing agreement following approval of VOQUEZNA for Erosive GERD, Phathom believes it will have sufficient capital to fund operations through the end of 2024.
