GRAPHIC

Phase 2 Clinical Trials Evaluating Multi-phage Candidates for the Treatment of Adults with Bacteremia due to Staphylococcus aureus (diSArm) and Chronic Respiratory Infections due to Pseudomonas aeruginosa (SWARM-P.a. & Tailwind) Mina Pastagia, MD, Stacey Kolar, PhD, Pierre Kyme, PhD, Thomas Feinberg, MS, Deborah Birx, MD Armata Pharmaceuticals, Inc., Los Angeles, California INTRODUCTION METHODS RESULTS* Novel therapeutics such as bacteriophage may be of clinical benefit in the treatment of challenging infections and respond to the need to combat antimicrobial resistance (AMR). Phages boast several potential advantages over conventional broad-spectrum antibiotics. As bactericidal agents with a narrow spectrum of activity, phages exert minimal disruption to normal flora, thereby exhibiting inherently lower toxicity profiles. Their efficacy extends to both antibiotic-sensitive and -resistant bacteria, rendering phage activity independent of prevailing antibiotic resistance patterns. Furthermore, phages demonstrate efficacy in disrupting bacterial biofilms, a feat poorly accomplished by antibiotics. Although phage therapy has enjoyed widespread utilization and success in human medicine, often serving as a last-resort salvage therapy, its safety and efficacy await conclusive validation through randomized, placebo-controlled clinical trials.1-3 Armata’s goal with the support of the U.S. Department of Defense is to prove the role of phage therapy through definitive pivotal trials addressing: • Phage therapy as an alternative or augmentation to antibiotics to prevent or delay resistance • Evidence that phage is non-inferior to standard-of-care antibiotics Advantages of phage therapy: • Targeted therapy while preserving the microbiome resulting in decreased patient morbidity • Ability to constantly update the phage cocktail based on evolution of bacteria at the population level • Antibiotic use eliminated or decreased OBJECTIVES 1. Administration of high doses of intravenous and inhaled phage for multiple days is well-tolerated in human clinical trial subjects 2. Systemic and local phage remain active in the blood and lungs, respectively when administered to human clinical trial subjects 3. Inhaled phage monotherapy may have similar bacterial load reduction as compared with antibiotics in human trial subjects diSArm is a Phase 1b/2a, placebo-controlled, multiple ascending dose escalation study of intravenous AP-SA02 as an adjunct to best available antibiotic therapy (BAT) compared to BAT alone. The trial has evaluated the safety and tolerability of AP-SA02 via IV bolus infusion every 6 hours for a period of 5 days in addition to BAT at 2 dose levels: 2 × 10⁹ PFU (Ph1b, Cohort 1) and 2 x 10¹⁰ PFU (Phase 1b, Cohort 2). The trial is actively enrolling subjects with complicated Staphylococcus aureus (S. aureus) bacteremia. Subjects in diSArm Phase 1b were dosed at 2 dose levels, for a total of 8 subjects. The dose was further increased in the enrolling Phase 2a. The study remains blinded. There have been no deaths or significant AEs precluding dose escalation. There is retention of phage activity from blood samples collected after dosing. Detection of phage despite 48 hours of antibiotics is observed in a subgroup of subjects (~50%), indicating that these subjects may have persistent S. aureus that the phage are potentially able to find and kill and is evidence of in vivo amplification. CONCLUSIONS* Multiple-dose administration of intravenous AP-SA02 and inhaled AP-PA02 have been well tolerated to date. Early pharmacokinetic data suggests intravenous AP-SA02 is active in all subjects, with longer phage persistence in a significant subset of subjects. This may garner increased clinical benefit for patients with difficult to treat S. aureus infections. Early evidence supports inhaled AP-PA02 monotherapy as a viable alternative to inhaled antibiotics in P. aeruginosa bronchiectasis. Promising data for both phage candidates is expected to be utilized for planning pivotal Phase 3 clinical trials in 2025. REFERENCES 1. Principi N, Silvestri E, Esposito S.

Armata Pharmaceuticals Announces Presentation at the 2024 Military Health System Research Symposium

 

LOS ANGELES, Calif., August 26, 2024 -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a biotechnology company focused on the development of high-purity, pathogen-specific bacteriophage therapeutics for antibiotic-resistant and difficult-to-treat bacterial infections, today announced that Mina Pastagia, M.D., MS, Chief Medical Officer, will deliver a poster presentation at the 2024 Military Health System Research Symposium (MHSRS), which is being held August 26-29 in Kissimmee, FL.

 

The poster provides an overview of Armata’s two distinct phage development programs, inhaled AP-PA02 (Pseudomonas aeruginosa bronchiectasis) and intravenous AP-SA02 (Staphylococcus aureus (S. aureus) bacteremia), which are being or have been evaluated in three distinct double-blind, placebo-controlled Phase 2 clinical trials.

 

Regarding AP-SA02, Armata is currently advancing its Phase 1b/2a multiple ascending dose study (diSArm) of intravenous AP-SA02 as an adjunct to best available antibiotic therapy (BAT) compared to BAT alone. Enrollment of the diSArm study is 80% complete, and Armata anticipates completing enrollment by the end of 2024.

 

The clinical development of AP-SA02 is supported by a $21.6 million Department of Defense grant, received through the Medical Technology Enterprise Consortium (MTEC) and managed by the Naval Medical Research Command (NMRC) – Naval Advanced Medical Development (NAMD) with funding from the Defense Health Agency and Joint Warfighter Medical Research Program.

 

“We are excited to participate in this year’s MHSRS and highlight the rigorously designed double-blind, placebo-controlled clinical trials that we are executing for both of our phage candidates,” stated Dr. Pastagia. “Through our completed and ongoing Phase 2 trials, our phage candidates have been well tolerated, allowing us to evaluate higher phage doses that can increase the ability of our phages to fulfill their mechanism of action of attacking only pathogenic bacteria. This in turn is expected to provide Armata with the necessary data to inform how best to administer phage therapy and decrease the usage of broad-spectrum antibiotics so as to preserve the human microbiome in an effort to lower patient morbidity. We greatly appreciate the collaborative partnership with the NMRC and NAMD as well as MTEC for its financial support of our AP-SA02 program. We look forward to advancing both AP-SA02 and AP-PA02 into pivotal Phase 3 trials next year with the hope of introducing a distinct new class of anti-infectives to patient care.”

Date/time:Tuesday, August 27, 10:00 am – 12:00 pm EDT

 

Summary: Multiple-dose administration of intravenous AP-SA02 and inhaled AP-PA02 have been well tolerated to date. Preliminary pharmacokinetic data suggests intravenous AP-SA02 is active in all subjects, with longer phage persistence in a significant subset of subjects potentially demonstrating a persistent reservoir of S. aureus bacteria (despite antibiotics) and in vivo amplification of the phages. This may garner increased clinical benefit for patients with difficult-to-treat S. aureus infections. Preliminary evidence supports inhaled AP-PA02 monotherapy as a viable alternative to inhaled antibiotics in Pseudomonas aeruginosa bronchiectasis. Promising data for both phage candidates is expected to be utilized for planning pivotal Phase 3 clinical trials in 2025.

16 Ph1b/2a SWARM - P.a. Study With Inhaled AP - PA02: Completed 1Q23 Outpatient Study in CF Adults with Chronic Pulmonary Pseudomonas aeruginosa Infections Study Objectives Key Inclusion Criteria Study Design (25 US sites) ≥10⁴ CFU of Pa per gram of induced sputum at Screening Pa isolates sensitive to AP - PA02, based on Screening sputum morphotypes For SAD: FEV1 ≥ 60% of predicted normal For MAD: FEV1 ≥ 40% of predicted normal Stable lung function: FEV1 at the Baseline Visit has not decreased by more than 5% compared to the FEV1 at Screening

 

17 Learnings for SWARM - P.a. Ph1b/2a CF Study AP - PA02 Well - Tolerated with Consistent Exposures by Dose Learnings Safety and Tolerability for up to 10 days bid dosing • No dose - limiting toxicity • No AEs >Grade 1 attributed to study drug: Grade 1 AEs appear to be intermittent with quick recovery Distribution and Clearance • Very low to undetectable systemic exposure after inhalation; no phage detected in urine • Initial assessment of clearance supports q12H dosing Pharmacodynamics (Target Engagement) • Single dose insufficient for CFU reduction • CFU reduction in highest - dosed subjects with higher trough levels (sustained exposure) • Trough level and schedule are key NCFB Phase 2 Tail wind study evaluates optimized dose and schedule

 

18 NCFB Phase 2 Tail wind Study Design Evaluate AP - PA02 as Monotherapy and in Combination with Inhaled Antibiotics • AP - PA02 nebulized q12h x 10 days • Subject dosing at home • Started with highest dose from CF study (increased dose 2X after lead in) • Evaluate optimized AP - PA02 exposures in correlation with bacterial load reduction and durability Cohort A Cohort B NCFB + confirmed chronic PA infection (Not on chronic inhaled abx) NCFB + confirmed chronic PA infection (On chronic inhaled abx) AP - PA02 bid x 10 days Placebo bid x 10 days AP - PA02 bid x 10 days + SOC inhaled Abx x 28 days SOC Inhaled Abx x 28 days Study Day Study Drug Administration 1 10

 

19 NCFB Phase 2 Tail wind Study: Fully Enrolled Top - Line Data Expected 2H2024 Enrollment Summary • Accelerated enrollment since 3Q23 • 48 subjects dosed (100%) • 23 sites activated Preliminary Insights into Inhaled AP - PA02* • Multiple - dose administration well tolerated; no significant safety signals • AP - PA02 treated subjects demonstrate a decline in Pseudomonas CFU that persists after treatment has completed • Potential for phage monotherapy as an alternative to rather than in addition to inhaled antibiotics Met Target of Enrollment Completion Mid - 2024 * Preliminary findings are subject to change pending complete data that will be presented in the future

 

20 Ph3 NCFB Study Design Considerations Evaluation of AP - PA02 Monotherapy as First Approved NCFB Therapeutic Study Objectives / Endpoints Effect of inhaled AP - PA02 monotherapy, administered BID x 48 weeks ** compared to placebo in NCFB chronically infected with P. aeruginosa : • Frequency of pulmonary exacerbations: Reduction by ~30 % • Respiratory function • QoL, respiratory symptoms • Bacterial load reduction ** dosing might be continuous vs. on/off schedule, pending trial data.
