Armata Pharmaceuticals, Inc. (NYSE American: ARMP) is a clinical-stage biotechnology company at the forefront of developing high-purity, pathogen-specific bacteriophage therapeutics to tackle the growing global threat of antibiotic-resistant bacterial infections. With a robust pipeline targeting chronic pulmonary diseases and acute systemic infections, Armata is poised to redefine the treatment landscape through its innovative phage-based approach.
Business Overview and History
Armata Pharmaceuticals, Inc. was founded in 2015 with a mission to harness the power of bacteriophages – viruses that selectively target and destroy bacteria – to combat the rising tide of antibiotic resistance. The company's origins are rooted in the development of a proprietary bacteriophage-based technology platform designed to create pathogen-specific therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections.
Over the past several years, Armata has meticulously built a comprehensive platform for the identification, characterization, and development of phage-based therapeutics. The company's proprietary technology enables the production of high-purity, pathogen-specific phage cocktails tailored to treat a wide range of bacterial infections, including those caused by multidrug-resistant strains.
Armata's clinical pipeline is anchored by two lead candidates: AP-PA02, an inhaled phage therapy targeting chronic pulmonary Pseudomonas aeruginosa infections, and AP-SA02, an intravenous phage therapy for the treatment of Staphylococcus aureus bacteremia. Both programs have demonstrated promising results in early-stage clinical trials, positioning the company for potential pivotal studies in the near future.
In 2020, Armata secured a $15 million grant from the U.S. Department of Defense's Medical Technology Enterprise Consortium (MTEC) to support the development of AP-SA02. This non-dilutive funding has been instrumental in advancing the bacteremia program, with the company recently announcing the completion of enrollment in the Phase 1b/2a diSArm study. Topline data from this trial is anticipated in the first quarter of 2025, potentially paving the way for a pivotal efficacy study later that year.
Armata's second lead candidate, AP-PA02, has also made significant strides. In 2023, the company reported positive topline results from the SWARM-P.a. Phase 1b/2a trial, which evaluated the safety and tolerability of inhaled AP-PA02 in cystic fibrosis patients with chronic P. aeruginosa infections. Building on this success, Armata initiated the Tailwind Phase 2 study in 2022 to assess AP-PA02 in non-cystic fibrosis bronchiectasis (NCFB) patients with similar chronic pulmonary infections. The Tailwind study completed enrollment in the third quarter of 2024, and topline data is expected by the end of the year, potentially setting the stage for a pivotal bronchiectasis trial in 2025.
To support its ongoing operations and research efforts, Armata has actively pursued various funding options. In 2023, the company received a significant financial boost from its principal shareholder, Innoviva, in the form of a $30 million convertible loan and a $25 million term loan. This financing, combined with the non-dilutive grant funding from MTEC, has been crucial in enabling Armata to progress its phage therapy pipeline and advance its clinical programs.
Financial Overview
Armata's financial performance has been primarily driven by its focus on research and development activities, as the company continues to advance its phage-based therapeutic candidates through clinical trials. As a clinical-stage biotechnology company, Armata has not yet generated significant revenue from product sales, relying instead on grant funding and capital raised through equity and debt financing to support its operations.
For the nine months ended September 30, 2024, Armata reported grant revenue of $3.94 million, a slight increase compared to the $3.00 million recorded in the same period of the prior year. This grant revenue is primarily associated with the MTEC funding for the development of AP-SA02.
Research and development expenses for the nine-month period ended September 30, 2024, amounted to $25.98 million, remaining relatively flat compared to the $25.84 million incurred in the corresponding period of 2023. The company's focus on advancing its lead candidates through clinical trials has been the primary driver of these expenses. Specifically, $5.46 million was dedicated to the AP-PA02 NCFB trial, while $2.75 million was allocated to the AP-SA02 bacteremia trial.
General and administrative expenses, which include costs related to Armata's corporate operations and infrastructure, increased from $8.47 million in the first nine months of 2023 to $9.86 million in the same period of 2024. This increase was largely attributable to higher stock-based compensation expenses and lease-related costs.
During the nine months ended September 30, 2024, Armata reported a net loss of $21.52 million, a significant improvement compared to the $49.20 million net loss recorded in the same period of the prior year. This reduction in net loss was primarily driven by gains in the fair value of the company's convertible debt, partially offset by higher interest expenses.
For the most recent quarter, Armata reported no revenue, a net loss of $5.48 million, operating cash flow of -$8.86 million, and free cash flow of -$9.20 million. Year-over-year growth figures were not provided.
Liquidity
As of September 30, 2024, Armata had cash and cash equivalents of $17.14 million, which, combined with the remaining MTEC grant funding, is not sufficient to fund the company's operations for the next 12 months. Armata is actively exploring various funding options, including public and private equity offerings, debt financings, and potential collaborations, to secure the necessary resources to advance its clinical programs and support its ongoing operations.
On March 4, 2024, the company entered into a $35 million secured credit agreement with Innoviva Strategic Opportunities LLC, providing additional financial flexibility. Furthermore, on November 12, 2024, Armata amended its Convertible Credit Agreement and 2023 Credit Agreement to extend the maturity dates, further improving its liquidity position.
The company's current ratio and quick ratio both stand at 0.1894, indicating potential short-term liquidity challenges. Armata does not provide a specific debt-to-equity ratio, but the recent credit agreements and amendments suggest a significant reliance on debt financing to support its operations.
Operational Highlights and Milestones
Armata's operational focus has been centered on the clinical development of its two lead phage candidates, AP-PA02 and AP-SA02, as the company works to establish the safety, tolerability, and efficacy of these novel therapeutics.
In the chronic pulmonary disease space, the completion of enrollment in the Tailwind Phase 2 study of inhaled AP-PA02 in NCFB patients with P. aeruginosa infections was a significant milestone achieved in the third quarter of 2024. The company anticipates topline data from this trial by the end of the year, which could pave the way for a pivotal bronchiectasis study in 2025.
The Tailwind study enrolled subjects both on and off chronic inhaled antibiotics to analyze AP-PA02 as monotherapy as well as in combination with inhaled antibiotics.
