Armata Pharmaceuticals Announces Third Quarter 2025 Results and Provides Corporate Update

LOS ANGELES, Nov. 12, 2025 /PRNewswire/ -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) ("Armata" or the "Company"), a clinical-stage biotechnology company focused on the development of high-purity, pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections, today announced financial results for its third quarter ended September 30, 2025, and provided a corporate update.

Third Quarter 2025 and Recent Developments:

• Highlighted positive results from Phase 2a "diSArm" study of Armata's lead therapeutic phage candidate, AP-SA02, as a potential treatment for complicated Staphylococcus aureus ("S. aureus") bacteremia ("SAB") at IDWeek 2025^TM, on October 22 in Atlanta, Georgia. The abstract was accepted as a late-breaking abstract for oral presentation and was presented by Dr. Loren G. Miller, M.D., M.P.H., Professor of Medicine, David Geffen School of Medicine at UCLA, Chief, Division of Infectious Diseases at Harbor-UCLA Medical Center and the Lundquist Institute.
  • AP-SA02 combined with Best Available Antibiotic Therapy ("BAT") had a higher and earlier cure rate compared to placebo (BAT alone) in patients with complicated SAB at day 12 as assessed by both blinded site investigators and independent adjudicators. Additionally, patients who received AP-SA02 demonstrated 100% response rate without relapse one week post-BAT and 28 days later at End of Study when compared to the placebo (BAT alone) group which showed approximately 25% lack of response or relapse at both timepoints.
  • AP-SA02 was well-tolerated with clinical efficacy against both methicillin-resistant S. aureus and methicillin-sensitive S. aureus, and patients treated with AP-SA02 showed trends toward rapid normalization of key predictors of mortality and complications in SAB including C-reactive protein and interleukin-10, shorter time to negative blood culture, quicker time to resolution of signs and symptoms at the infection site, and shorter intensive care unit and hospital utilization.
• Announced that its state-of-the-art current Good Manufacturing Practice ("cGMP") manufacturing facility in Los Angeles, California, has been formally commissioned. Full production runs have been completed with no issues or concerns.
  • Armata's 56,000 square foot facility includes 10,000 square feet of cGMP clean rooms, an automated fill and finish suite, and quality control laboratories, to support future clinical trials and full commercialization as well as potential partnering and contract manufacturing opportunities.
  • Aligns with the federal government's focus on onshoring manufacturing to secure the supply chain of essential medicines for the health and safety of the American people.
  • Aligns with the need to confront the growing antimicrobial resistance crisis and the risk of bacterial escape from current antibiotics.
• Entered into a secured credit agreement with Innoviva Strategic Opportunities LLC, a wholly owned subsidiary of Innoviva, Inc., Armata's largest shareholder, for a loan of $15.0 million that will mature on January 11, 2029, the proceeds of which are being used to continue to advance development of AP-SA02.
• Further advanced bacteriophage science through a structural biology publication in the Journal of Molecular Biology.
• Participated in the H.C. Wainwright 27^th Annual Global Investment Conference.

"Compelling efficacy data from the Phase 1b/2a randomized controlled study of intravenously administered AP-SA02, including the favorable safety and tolerability profile, underscore the precision infection control enabled by Armata's well-characterized, high-purity phage cocktails, and provide strong rationale for advancement of AP-SA02 into late-stage clinical development," stated Dr. Deborah Birx, Chief Executive Officer of Armata. "Subject to review and feedback from the U.S. Food and Drug Administration, we are committed to developing a superiority pivotal trial with the goal of introducing AP-SA02 as a new standard of care for complicated Staphylococcus aureus bacteremia, a common, extremely severe, and often deadly infection."

"With the full commissioning of our state-of-the-art cGMP manufacturing facility in Los Angeles, California, we are now operationally ready to scale production for late-stage clinical development. We reiterate our commitment to U.S.-based manufacturing in support of the federal government's efforts to secure the pharmaceutical supply chain through onshore manufacturing of essential medicines. We have made tremendous progress this year advancing phage-based therapeutics as potential treatments for both acute and chronic bacterial infections, and with line-of-site to the potential initiation of a Phase 3 study in 2026, we believe we are well positioned to bring new hope to patients with significant unmet medical need, while creating long-term value for our shareholders," Dr. Birx concluded.
