Non-dilutive funding to be used to advance the company’s second phage-based therapeutic candidate in a Phase 1b/2 clinical study

MARINA DEL REY, CA, USA I June 17, 2020 I Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant and difficult-to-treat bacterial infections, today announced that it has received a $15 million award for a three year program from the U.S. DoD through the Medical Technology Enterprise Consortium (MTEC) with funding from the Defense Health Agency and Joint Warfighter Medical Research Program. Armata will use the award to partially fund a Phase 1b/2, randomized, double-blind, placebo-controlled, dose escalation clinical study of Armata’s therapeutic phage-based candidate, AP-SA02, for the treatment of complicated Staphylococcus aureus bacteremia infections.

“Today, I am pleased to announce that we have achieved our goal of receiving non-dilutive funding to support clinical development of our optimized phage candidate, AP-SA02, as a promising potential treatment for S. aureus bacteremia. We are excited to have exceeded the amount of funding we had originally targeted, which enables us to robustly examine the potential efficacy of our optimized phage candidate,” stated Todd R. Patrick, Chief Executive Officer of Armata Pharmaceuticals. “This funding from the DoD validates the potential of phage-based therapeutics and helps us move AP-SA02 into clinical development while continuing to carefully manage our financial position. Drug-resistant S. aureus bacteremia infections carry mortality rates as high as 40%, reflecting the urgent need for novel and improved treatment options.”

Mr. Patrick added, “This award from the DoD facilitates what will be our second clinical program in our  development pipeline, enabling Armata to advance phage therapy in two distinct indications: our lead program, AP-PA02, will explore inhaled phage therapy in cystic fibrosis patients with Pseudomonas aeruginosa lung infections and is partially funded by the US Cystic Fibrosis Foundation, and AP-SA02, which will test intravenous phage therapy in S. aureus bacteremia and is partially funded by the DoD.”

Thomas Dunn, Acting Program Manager Naval Advanced Medical Development, stated “Antibiotic resistance is a global challenge and has become more prevalent in recent years, threatening the lives of both warfighters and civilians. There is an imminent need for alternative therapies to help protect the population. Using Armata’s targeted phage cocktail to treat Staphylococcus aureus bacteremia that are non-responsive to standard of care is a novel method that can potentially greatly reduce the number of these complicated, drug-resistant infections and help span the ever-growing bacteria / antibiotic resistance gap.”

The primary objectives of the Phase 1b/2 bacteremia study will be to evaluate the safety and tolerability of AP-SA02 as an adjunct to best available antibiotic therapy, and to determine the appropriate dose or doses for future clinical trials of efficacy. Because of the impact of COVID-19 on the Company’s development programs, Armata does not believe the clinical trial will initiate prior to mid-2021.  The clinical trial of AP-PA02 targeting Pseudomonas aeruginosa is on target to enroll later this year.  

About Bacteremia

Bacteremia is a bacterial infection of the bloodstream. A common diagnosis, the Centers for Disease Control and Prevention (CDC) estimates that up to 1.7 million people in the United States develop bacteremia each year. S. aureus is the most commonly identified pathogen in both hospital- and community-acquired blood stream infections. Annually in the United States there are approximately 200,000 hospitalizations for S. aureus bacteremia (SAB). Despite conventional antibiotics, mortality in SAB results in death of up to 40% of all cases and 57% of patients over the age of 85. Patients with comorbidities such as alcoholism, malignancy, diabetes, end-stage renal disease requiring hemodialysis, and immunosuppression are at even higher risk for death when SAB develops. Age-adjusted mortality assessments show that SAB mortality is higher than that of AIDS, tuberculosis, or viral hepatitis, and comparable to mortality rates for breast or prostate cancer. Outcomes are even poorer for SAB due to methicillin-resistant S. aureus (MRSA), classified as a serious threat to global health by the CDC and a high priority threat by the World Health Organization, with higher rates of complications and increased mortality as compared to methicillin-susceptible S. aureus (MSSA). Average hospital costs to patients with nosocomial SAB ranges between $40,000 (MSSA) and $114,000 (MRSA). Treatment failures are common in SAB, with highest rates due to MRSA. These failures can be attributed in part to poor penetration of some tissues by antibiotics, slow onset of bactericidal effects, emerging resistance patterns, and biofilm formation. While biofilms can render traditional antibiotics ineffective, phages may have the ability to penetrate the biofilm allowing rapid and efficient infection of the host and amplification at the site of infection. Daptomycin (approved in 2005; based on clinical cure rates of <50%) and vancomycin are the only two antibiotics with label indications in the United States for the treatment of SAB, and the emergence of drug-resistant S. aureus isolates, including to these two standard of care drugs, represents a major threat in terms of increasing morbidity, mortality and health care utilization.
