FLORHAM PARK, N.J., Nov. 07, 2024 (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 of 2024, and provided recent business updates.

“We are thrilled with Phathom’s progress over the past quarter, particularly the strong and continued momentum of the commercial launch for our first-in-class gastroesophageal reflux disease (GERD) treatment, VOQUEZNA,” said Terrie Curran, President and CEO of Phathom. “Demand from physicians and patients has been robust, and favorable payer coverage continues to expand, now reaching over an estimated 120 million U.S. commercially covered lives. These positive trends in prescription data, market sentiment, and patient access validate our launch strategies and reinforce our confidence in the potential of VOQUEZNA to displace standard of care proton pump inhibitors (PPIs). The recent approval for Non-Erosive GERD has greatly expanded our market opportunity, and the strong demand highlights the high unmet need in GERD treatment. Additionally, our successful $130 million equity raise further strengthens our ability to invest in the growth of the brand and we believe we remain well-positioned to deliver on VOQUEZNA’s blockbuster opportunity.”

Recent Business Highlights and Third Quarter 2024 Results:

VOQUEZNA Launch Progress:

• VOQUEZNA's commercial momentum continues to accelerate, bolstered by the July 2024 label expansion to include Non-Erosive GERD. Total filled prescriptions grew steadily throughout the third quarter, underscoring strong market adoption and positive feedback from both healthcare providers and patients. Launch to date through October 25, 2024, over 143,000 prescriptions for VOQUEZNA tablets, VOQUEZNA TRIPLE PAK^®, and VOQUEZNA DUAL PAK^® have been filled through both retail pharmacies and patient support at BlinkRx, an increase of 138% compared to 60,000 filled prescriptions as of the company’s last quarterly report. The sequential growth of prescriptions filled in the third quarter 2024 nearly doubled with over 69,000 prescriptions for VOQUEZNA products filled, compared to approximately 35,000 filled prescriptions in the second quarter 2024.
  
• As the launch progresses, VOQUEZNA’s prescriber base continues to expand with the number of VOQUEZNA prescribers growing to more than 13,600 cumulative prescribers as of October 18, 2024, up from 8,200 writers since the company’s last quarterly report, an increase of over 65%.
  
• Phathom has secured broad and favorable commercial coverage for VOQUEZNA, with access now expanded to over an estimated 120 million covered lives, representing over 80% of U.S. commercial lives.
  

Recent Business and Regulatory Highlights:

• New data from multiple studies for first-in-class treatment VOQUEZNA were presented at the American College of Gastroenterology (ACG) 2024 Annual Meeting, held October 25-30 in Philadelphia, PA:
  
  • A new analysis of data from the Phase 2 PHALCON-NERD-201 trial assessing additional clinical outcomes related to the efficacy of investigational As Needed (On-Demand) VOQUEZNA dosing compared to placebo for relieving episodic heartburn in Non-Erosive GERD patients following a 4-week daily VOQUEZNA run-in period was presented by Ronnie Fass, M.D. This research was recognized with the ACG Outstanding Research Award and highlighted the potential for transitioning from daily VOQUEZNA treatment to As Needed dosing of VOQUEZNA, showing symptom improvement within one hour of VOQUEZNA administration and sustained low heartburn burden in patients who switched to As Needed treatment after achieving control with daily use.
    
  • In a poster presentation recognized with ACG’s prestigious Presidential Poster Award, an exploratory analysis from Phathom's Phase 3 Non-Erosive GERD study assessed the common yet infrequently evaluated nocturnal symptoms among Non-Erosive GERD patients. Patients with nighttime GERD prior to VOQUEZNA treatment reported significant and meaningful relief with VOQUEZNA daily dosing, further underscoring VOQUEZNA’s potent and long-lasting acid suppression and potential in addressing both daytime and nighttime heartburn.
    
• Phathom’s recent launch of VOQUEZNA for Non-Erosive GERD has begun to generate real-world data which is being reviewed to understand consumer usage patterns and prescribing habits of healthcare providers. These insights will help assess the value and potential timing for advancing a separate Phase 3 program to validate the As Needed dosing of VOQUEZNA for active heartburn episodes, building on the positive results from the company's prior Phase 2 study.
  
• Phathom is in the final stages of obtaining FDA feedback on the Phase 2 study and program investigating VOQUEZNA as a potential treatment for Eosinophilic Esophagitis (EoE) in adults and adolescents, with plans to now initiate the program in the first half of 2025.
  

Third Quarter 2024 Financial Results:

• Revenue: Net revenues for the third quarter 2024 were $16.4 million related to sales of VOQUEZNA, VOQUEZNA TRIPLE PAK, and VOQUEZNA DUAL PAK. There were no revenues for the third quarter 2023 due to the launch of VOQUEZNA taking place in the fourth quarter 2023.
  
• Research and development (R&D) expenses: R&D expenses for the third quarter 2024 were $8.7 million, a decrease of $3.6 million compared to $12.3 million for the third quarter 2023. The decrease was a result of lower clinical trial expenses due to the wrap-up of activities related to the PHALCON-NERD-301 daily dosing study.
  
• Selling, general and administrative (SG&A) expenses: SG&A expenses for the third quarter 2024 were $76.1 million, an increase of $52.7 million compared to $23.4 million for the third quarter 2023. The increase was a result of higher personnel costs and increased activity related to the ongoing buildout of commercial infrastructure and marketing activity in support of the launch of VOQUEZNA products.
  
• Net loss: Net loss for the third quarter 2024 was $85.6 million, compared to $43.2 million for the third quarter 2023. Third quarter 2024 net loss included a non-cash charge related to stock-based compensation of $5.6 million compared to $6.1 million for the third quarter 2023. Non-GAAP adjusted net loss for the third quarter 2024 was $67.9 million compared to $30.8 million for the same period in 2023. These non-GAAP adjusted net losses, more fully described below under "Non-GAAP Financial Measures," exclude non-cash stock-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, 2024, cash and cash equivalents were $334.7 million. Up to an additional $125 million is also available under the Company’s term loan with Hercules.
• Cash runway: Based on its current cash resources, operating plan, estimated product revenues, and potential funds available under its existing term loan, the company believes these resources will be sufficient to fund operations and enable Phathom to achieve cash flow positivity.
  

Conference Call and Webcast
Phathom will host a conference call and webcast to discuss its third quarter financial results and business highlights today, November 7, 2024, at 8:30 am ET.

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 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 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.
