FLORHAM PARK, N.J., Oct. 30, 2025 (GLOBE NEWSWIRE) --  Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal (GI) diseases, today reported financial results for the third quarter ended September 30, 2025, and provided a business update.

“Our performance this quarter reinforces our belief in the strength of our GI-focused call strategy and reflects disciplined execution across the business,” said Steve Basta, President and Chief Executive Officer of Phathom. “Momentum for VOQUEZNA tablets continues to build as we deepen engagement with gastroenterologists. In the third quarter we grew revenues, reduced expenses, and reduced cash usage in line with our previously communicated plan. With strong commercial performance this quarter, continued expense discipline, and an experienced leadership team in place, we are advancing toward our goal of becoming a leader in GI.”

Recent Business Highlights and Third Quarter 2025 Results:

VOQUEZNA Commercial Progress:

• Over 790,000 filled prescriptions for VOQUEZNA tablets, VOQUEZNA TRIPLE PAK®, and VOQUEZNA DUAL PAK® as of October 17, 2025.
  
  
• In the third quarter 2025, approximately 221,000 VOQUEZNA prescriptions were filled, a 28% increase quarter over quarter. Covered prescriptions grew 23% during the third quarter and continue to be the primary driver of revenue.
  
  
• In July, sales force retargeting efforts commenced, focusing on deepening sales call engagement with gastroenterologists (GIs). In October, Phathom completed a national sales territory realignment consistent with this GI targeting focus.
  
  
• VOQUEZNA commercial coverage remains stable with greater than 80% of U.S. commercial lives covered.
  

Recent Business and Regulatory Updates:

• The Phase 2 pHalcon-EoE-201 trial evaluating VOQUEZNA in Eosinophilic Esophagitis (EoE) was initiated in October 2025, with patient screening underway and the first patient expected to be treated in the fourth quarter of 2025. Topline results are anticipated in 2027.
  
  
• Additional data from Phathom’s Phase 3 pHalcon-NERD-301 trial were recently published in the American Journal of Gastroenterology showing VOQUEZNA improved nocturnal GERD symptoms in patients with Non-Erosive Reflux Disease, including clinically meaningful increases in heartburn-free nights observed after the first dose and maintained through 24 weeks of treatment.
  
  
• Phathom strengthened its leadership team with the additions of Sanjeev Narula as Chief Financial and Business Officer and Nancy Phelan as Senior Vice President, Marketing and Analytics. Mr. Narula brings extensive experience in scaling commercial-stage biopharmaceutical companies, with expertise in finance, capital strategy, and operations, most recently serving as CFO at Intra-Cellular Therapies through its $14.6 billion acquisition by Johnson & Johnson. Ms. Phelan brings a digital-first, data-driven approach to commercialization and customer engagement, drawing on leadership roles at Novartis, Bristol Myers Squibb, Pfizer, and Schering-Plough.
  
  
• Phathom expects New Chemical Entity (NCE) exclusivity for VOQUEZNA 10 mg and 20 mg tablets through May 2032. Based on typical ANDA regulatory review timelines, the Company believes entry of a generic drug is unlikely before 2033.
  

Third Quarter 2025 Financial Results:

• Revenue: Net revenues for the third quarter 2025 were $49.5 million, an increase of $33.1 million compared to $16.4 million for the third quarter 2024.  
  
  
• Research and development (R&D) expenses: R&D expenses for the third quarter 2025 were $7.0 million, a decrease of $1.7 million compared to $8.7 million for the third quarter 2024.
  
  
• Selling, general and administrative (SG&A) expenses: SG&A expenses for the third quarter 2025 were $51.6 million, a decrease of $24.5 million compared to $76.1 million for third the quarter 2024. The decrease was primarily due to a reduction in advertising and promotional expenses, personnel-related expenses, and third-party spend.
  
  
• Operating expenses: Operating expenses for the third quarter 2025 were $58.6 million, compared to $84.8 million for the third quarter 2024 and $94.4 million during the second quarter 2025. The sequential decrease compared to the second quarter 2025 was attributable to cost savings associated with lower direct-to-consumer promotional spend, lower personnel-related expenses, and lower third-party spend. Third quarter 2025 operating expense included a non-cash charge related to stock-based compensation of $9.3 million compared to $5.6 million for the third quarter 2024 and $8.3 million for the second quarter 2025. Non-GAAP operating expenses for the third quarter 2025 were $49.3 million, compared to $79.2 million for the third quarter 2024 and $86.1 million during the second quarter 2025. As previously indicated, Phathom expects non-GAAP operating expenses to be less than $55 million for the fourth quarter 2025.
  
  
• Net loss: Net loss for the third quarter 2025 was $30.0 million, compared to $85.6 million for the third quarter 2024. Non-GAAP adjusted net loss for the third quarter 2025 was $11.2 million compared to $67.9 million for the same period in 2024. These non-GAAP adjusted net loss amounts, as more fully described below under "Non-GAAP Financial Measures," exclude non-cash share-based compensation charges, non-cash interest expense related to the accounting for our revenue interest financing liability, which are in excess of the actual interest owed, and interest expense related to the amortization of debt discount on our term loan. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below.
  
  
• Cash and cash equivalents: As of September 30, 2025, cash and cash equivalents were $135.2 million. Net cash usage was approximately $14 million in the third quarter 2025, representing a 77% improvement from net cash usage of approximately $63 million in the second quarter 2025. Based on its current operating plan and projected product revenues, Phathom believes these resources will be sufficient to fund operations and achieve operating profitability in 2026, excluding stock-based compensation, without the need for additional equity financing.
  
  
• Updated 2025 full year revenue guidance: Phathom updated full-year 2025 revenue guidance to $170 million to $175 million.
  

Conference Call and Webcast
Phathom will host a conference call and webcast to discuss its third quarter 2025 financial results and business highlights today, October 30, 2025, at 8:00 a.m. EDT.

Non-GAAP Financial Measures
This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also certain non-GAAP financial measures. In particular, Phathom has provided non-GAAP adjusted operating expense, net loss and adjusted net loss per share, adjusted to exclude the items below. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, Phathom believes the presentation of non-GAAP adjusted operating expense, net loss and adjusted net loss per share, when viewed in conjunction with GAAP results, provides investors with a more meaningful understanding of ongoing operating performance. These measures exclude (i) non-cash stock-based compensation, which is substantially dependent on changes in the market price of common shares, (ii) interest expense related to the accounting for our revenue interest financing liability, which are in excess of the actual interest owed, and (iii) interest expense related to the amortization of debt discount on our term loan.

Phathom believes the presentation of these non-GAAP financial measures provides useful information to management and investors regarding Phathom's results of operations. When GAAP financial measures are viewed in conjunction with these non-GAAP financial measures, investors are provided with a more meaningful understanding of Phathom's ongoing operating performance and are better able to compare Phathom's performance between periods. In addition, these non-GAAP financial measures are among those indicators Phathom uses as a basis for evaluating performance, and planning and forecasting future periods. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between these non-GAAP measures and the most directly comparable GAAP measures is provided later in this press release.
