Armata reports positive results for phage therapy trial

LOS ANGELES - Armata Pharmaceuticals, Inc. (NYSE American: ARMP), a clinical-stage biotechnology company with a current market capitalization of $48.85 million, announced today that its Phase 1b/2a clinical trial for AP-SA02, a bacteriophage therapy for Staphylococcus aureus bacteremia (SAB), met all primary endpoints for safety, tolerability, and clinical response in the intent-to-treat population. The study demonstrated significant improvement in clinical outcomes and prevention of relapse with AP-SA02 compared to the best available antibiotic therapy (BAT). According to InvestingPro data, while the company’s stock currently trades at $1.35, analysts have set a significantly higher target price of $7.

The randomized, double-blind, placebo-controlled trial evaluated the intravenous administration of AP-SA02 in addition to BAT. The trial included 50 subjects who received at least one dose of the phage therapy or placebo. AP-SA02 was well-tolerated, with no serious adverse events linked to the drug. Two subjects experienced adverse events possibly related to AP-SA02, which were resolved upon discontinuation of treatment.

Significant findings from the trial showed an 88% responder rate at the Test of Cure (TOC) for AP-SA02, compared to 58% for placebo, and by the end of the study, 100% of the AP-SA02 treated subjects had clinically responded versus 25% of placebo subjects considered non-responsive. The treatment was effective against both methicillin-sensitive and methicillin-resistant S. aureus.

Dr. Deborah Birx, CEO of Armata, emphasized the groundbreaking nature of the trial, noting it as the first clear evidence in a randomized controlled trial of phage efficacy against a serious systemic pathogen. She also highlighted the successful repetitive IV administration of high purity phage without significant safety concerns.

Armata’s capacity to manufacture drug product at its cGMP facility in California was underscored, with the ability to produce over 10,000 full courses of phage therapy annually. The positive trial results are propelling the company towards initiating a pivotal trial. InvestingPro analysis reveals the company generated $4.7 million in revenue over the last twelve months, though it faces challenges with cash burn and debt management.
