MARINA DEL REY, Calif., March 18, 2021 /PRNewswire/ — Armata Pharmaceuticals, Inc. (NYSE American: ARMP) (“Armata” or the “Company”), a biotechnology company focused on pathogen-specific bacteriophage therapeutics for antibiotic-resistant and difficult-to-treat bacterial infections, today announced results for the fourth quarter and full year 2020 and provided a corporate and clinical update.

Fourth Quarter 2020 and Recent Highlights:

• Announced FDA clearance of Investigational New Drug (IND) application to initiate Phase 1b/2a SWARM-P.a. clinical trial of lead candidate AP-PA02 in Pseudomonas aeruginosa infections
• Appointed biotechnology finance veteran Robin C. Kramer to its Board of Directors
• Hired Mina Pastagia, M.D., M.S., as Vice President of Clinical Development, adding significant expertise in the field of anti-infective development, including phage-based therapeutics
• Subsequent to the end of the fourth quarter 2020, the Company raised gross proceeds of $20.0 million through a securities purchase agreement with Innoviva Strategic Opportunities LLC, a wholly owned subsidiary of Innoviva, Inc., Armata’s largest shareholder

“During the fourth quarter and subsequent period, we made great progress across all aspects of our business,” stated Todd R. Patrick, Chief Executive Officer of Armata. “We took a significant step forward in the clinical development of our lead candidate, AP-PA02, and strengthened both our Board and leadership team. We also solidified our balance sheet which, together with remaining funds from the non-dilutive contract awards that we received last year, provide the resources to achieve meaningful milestones both this year and next.

“Looking ahead, in addition to initiating a Phase 1b/2 trial of AP-SA02 in Staphylococcus aureus bacteremia infections, we are also working toward the initiation of additional clinical trials assessing phage-based candidates in difficult to treat pathogens. Indications we are exploring include non-cystic fibrosis bronchiectasis, pneumonia and prosthetic joint infection. With an efficient clinical plan targeting several distinct indications, we believe we can play a key role in the advancement of phage therapy as a viable answer to the rise of antimicrobial resistance,” Mr. Patrick concluded.

Anticipated 2021 and 2022 Milestones:

• Complete the single ascending dose (SAD) cohort of the SWARM-P.a. Phase 1b/2a clinical trial evaluating AP-PA02 as a potential treatment for Pseudomonas aeruginosa infections in the coming months
• Initiate and complete the multiple ascending dose (MAD) cohort of SWARM-P.a. trial in late 2021/early 2022
• Initiate a Phase 1b/2 clinical trial evaluating AP-SA02 as a potential treatment for Staphylococcus aureus bacteremia
• Initiate at least one additional clinical trial using either of its two lead phage product candidates or slightly altered mixtures of phage products in an additional indication

Fourth Quarter Financial Results

Grant Revenue. The Company recognized grant revenue of $0.5 million for the three months ended December 31, 2020, which represents MTEC’s share of the costs incurred for the Company’s AP-SA02 program for the treatment of Staphylococcus aureus bacteremia. For the full year 2020, the Company recognized grant revenue of $0.8 million. The Company recognized no grant revenue in 2019.

Research and Development. Research and development expenses for the three months ended December 31, 2020 were approximately $5.0 million as compared to $1.7 million for the comparable period in 2019. The increase was primarily related to the increase in clinical trial and personnel related expenses. For the full year 2020, research and development expenses were $14.4 million as compared to $9.8 million for the full year 2019. Research and development expenses for the full year 2019 included a credit of $1.3 million for Australian tax rebates received.

General and Administrative. General and administrative expenses for the three months ended December 31, 2020 were $2.0 million as compared to $2.0 million for the comparable period in 2019. For the full year 2020, general and administrative expenses were $8.0 million as compared to $9.3 million for the full year 2019. The net decrease of $1.3 million for the full year was driven by a reduction in share-based compensation and lower professional expenses in 2020 as compared to those expenses incurred in 2019.

Loss from Operations. Loss from operations for the three months ended December 31, 2020 was $(6.5) million as compared to a loss from operations of $(4.4) million for the comparable period in 2019. For the full year 2020, loss from operations was $(21.6) million as compared to a loss from operations of $(19.8) million for the full year 2019.

Cash and Equivalents. As of December 31, 2020, Armata held approximately $9.7 million of unrestricted cash and cash equivalents, as compared to $6.0 million as of December 31, 2019. Subsequent to the end of the fourth quarter 2020, the Company raised gross proceeds of $20.0 million through the sale of common stock to Innoviva Strategic Opportunities LLC, a wholly owned subsidiary of Innoviva, Inc. (Nasdaq: INVA), Armata’s largest shareholder. Management believes the Company’s existing resources will be sufficient to fund planned operations into the first quarter of 2022.

The audit opinion included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 contains a going concern explanatory paragraph.

As of March 18, 2021, there were approximately 24.9 million shares of common stock outstanding.
