About Pacgen

Pacgen is a life sciences company focused on the development of therapeutics for the treatment of infectious and inflammatory diseases. Pacgen’s current development efforts are focused on PAC-113, an anti-fungal for the treatment of oral candidiasis and PAC-G31P, a novel peptide therapeutic designed to treat inflammatory diseases characterized by non-beneficial neutrophil.

PAC-113 is a 12 amino-acid antimicrobial peptide derived from a naturally occurring histatin protein found in saliva. This peptide alters the permeability of fungal cell membranes causing cell death. In June 2008, Pacgen announced positive results from its Phase IIb clinical trial demonstrating that PAC-113 is effective in the treatment of oral candidiasis and compares favourably to the efficacy demonstrated by Nystatin, a current standard of care. PAC-G31P is a small recombinant protein that is a synthetic analogue of the human cytokine called Interleukin-8 which is the key chemokine involved in neutrophil recruitment. PAC-G31P is currently being investigated in preclinical studies for its potential to treat inflammatory diseases characterized by non-beneficial neutrophil. For additional information, please visit
