Armata Pharmaceuticals Announces $20 Million Investment to Support Advancement of the Company's Bacteriophage Development Programs

MARINA DEL REY, Calif., Jan. 27, 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 that it has entered into a securities purchase agreement to sell Armata common stock and warrant securities to Innoviva Strategic Opportunities LLC, a wholly-owned subsidiary of Innoviva, Inc. (Nasdaq: INVA) (collectively, "Innoviva"), Armata's largest shareholder. The gross proceeds to the Company from the transaction are expected to be approximately $20 million, before deducting the advisor's fee and other estimated offering expenses payable by the Company.

Armata intends to use the net proceeds for the ongoing advancement of its bacteriophage development programs, including its FDA cleared first-in-human study, SWARM-P.a., which is evaluating the Company's lead phage product candidate, AP-PA02, as a potential treatment for Pseudomonas aeruginosa airway infections in cystic fibrosis patients, as well as for general working capital. In addition, the Company expects to initiate a second clinical trial related to another product candidate, AP-SA02, a phage targeting Staphylococcus aureus, in patients with complicated bacteremia later this year.

"Multi-drug resistant bacterial infections are a serious and growing public health threat, and with two strong therapeutic candidates and a robust team to drive clinical development, we believe we are well positioned to be a leader in the innovative field of phage therapy," said Todd R. Patrick, Chief Executive Officer of Armata. "We are grateful for this continued financial support from Innoviva and pleased that they share our vision for the great potential of bacteriophage therapeutics.

"The proceeds from this transaction, together with our cash on hand and the $20 million in non-dilutive contract awards received in 2020, place us in a strong financial position to achieve meaningful clinical milestones this year and next," Mr. Patrick concluded.

Pursuant and subject to the terms and conditions of the securities purchase agreement and related agreements, Innoviva will purchase approximately 6.2 million newly issued shares of Armata's common stock, at a price of $3.25 per share, and warrants to purchase up to approximately 6.2 million additional shares of Armata's common stock, with an exercise price of $3.25 per share.  The stock purchases are expected to occur in two tranches.  Upon execution, Innoviva purchased approximately 1.9 million shares of common stock and warrants to purchase approximately 1.9 million shares of common stock for an aggregate purchase price of approximately $6.1 million.  At the closing of the second tranche, upon Armata stockholders voting in favor of the transaction, Innoviva will purchase approximately 4.3 million shares of common stock and warrants to purchase approximately 4.3 million shares of common stock for an aggregate purchase price of $13.9 million.

Subject to the satisfaction of certain closing conditions, including the approval of Armata's stockholders, the second closing contemplated by the securities purchase agreement is expected to occur at the end of the first quarter of 2021. The shareholders of Armata will receive a proxy statement seeking approval of the second closing in the coming weeks.

Armata expects to achieve the following milestones in 2021 and 2022:

  • 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 in an additional indication.

Armata received legal advice in the transaction from Thompson Hine LLP, and Ladenburg Thalmann & Co. Inc. acted as financial advisor. 

Willkie Farr & Gallagher LLP provided legal advice to Innoviva.
