Exeporfinium (XF-73), a dicationic porphyrin derivative, is an antibacterial drug. Exeporfinium acts via a bacterial cell-surface mechanism that affects membrane permeability and integrity, leading to release of intracellular components and bacterial cell death, without lysis. Exeporfinium represents a broad-spectrum Gram-positive antibacterial drug. It also has activity against a number of Gram-negative bacteria. Exeporfinium has been granted Fast Track designation by the US FDA for the prevention of post-surgical staphylococcal infections such as Methicillin Resistant Staphylococcus aureus.

Sample Use Guides

In Vivo Use Guide

Phase 2 study: 0.3 mL applications in each naris of 0.2% w/w exeporfinium (XF-73) nasal gel for a cumulative dose of 6.0 mg of XF-73.

Route of Administration: Nasal

In Vitro Use Guide

XF-73 was active [minimum inhibitory concentration (MIC) 0.25-4 mg/L] against all of the Gram-positive bacteria tested, irrespective of the antibiotic resistance profile of the isolates, suggesting that the mechanism of action of XF-73 is unique compared with the major antibiotic classes. Gram-negative activity was lower (MIC 1 mg/L to > 64 mg/L).
