Ampliphi Biosciences (APHB) Stock Price, News & Analysis

Company Overview

Ampliphi Biosciences, Inc. is a clinical‐stage biopharmaceutical company headquartered in Cambridge, Massachusetts, focused on the discovery and development of novel therapies to prevent and treat life‐threatening drug‐resistant infections. The company’s core mission is to address the growing global threat of antibiotic resistance by advancing first‐in‐class and best‐in‐class antibacterial agents through late‐stage clinical trials.

The company’s lead product candidate, exeporfinium chloride (XF-73), is a pioneering topical antibacterial designed for pre‐operative nasal decolonization of Staphylococcus aureus in patients undergoing high‐risk surgical procedures. XF-73 has demonstrated the potential to significantly reduce surgical site infections by targeting nasal carriage of S. aureus, including methicillin‐resistant strains. Beyond XF-73, Ampliphi is expanding its pipeline through its proprietary drug conjugate platform, which seeks to create novel antibacterial compounds active against a broad spectrum of Gram‐negative and Gram‐positive pathogens.

Founded on a scientific foundation of antimicrobial innovation, Ampliphi Biosciences emerged following the strategic divestiture of earlier antifungal programs to a major pharmaceutical partner. The company operates primarily in North America and is preparing to extend its global footprint through strategic collaborations and licensing agreements. Ampliphi is supported by a leadership team with deep expertise in infectious disease drug development, manufacturing, and regulatory affairs, positioning the company to advance its candidates toward commercialization and address critical unmet needs in patient care.
