Armata reported positive Phase 2a diSArm results for AP-SA02 in complicated S. aureus bacteremia and highlighted a late-breaking IDWeek presentation. This signals clinical progress in its bacteriophage therapy program but provides no efficacy metrics or safety rates in the excerpt.

The disclosures are explicitly furnished under Item 7.01, meaning they are not deemed filed and carry different liability standards. Cash flows, revenue impact, or partnering terms are not addressed in the excerpt.

Subsequent company communications may add quantitative outcomes or next‑step plans; actual impact depends on detailed data and regulatory feedback not included here.
