PharmaGap Reports Improved Potency and Bioavailability Using Liposome Formulations of GAP-107B8

OTTAWA, ONTARIO--(Marketwire - May 19, 2011) - PharmaGap Inc. (TSX VENTURE:GAP)(OTCBB:PHRGF) ("PharmaGap" or "the Company") today reports promising early results of internal testing of liposome formulations of its cancer drug GAP-107B8. In these tests, liposome prototypes loaded with GAP-107B8 have been shown to be significantly more potent than either peptide alone or the liposome carrier alone in both the ovarian and bladder cancer cell lines tested. These results establish that the GAP-107B8 peptide is bioavailable when formulated in liposomes.

The ovarian and bladder cancer cell lines tested were selected from those that the Company routinely screens and comprise both sensitive and resistant cell lines. Although some cell lines were more responsive than others, in all cases the GAP-107B8 loaded liposome formulations proved efficacious and reduced the dose level of GAP-107B8 required to effectively inhibit cell growth.

Testing of a number of liposomal formulations will continue employing different concentrations of peptide and liposome compositions, cell lines, GAP-107B8 components and liposome formulations in order to lead the Company to the final form of drug for each cancer type and route of administration, one of which will be selected for initial clinical trials by the end of the current year.

Data analysis will continue in order to determine statistical magnitude of effect from this initial data and from the results of further testing.

Liposomes are microscopic carriers with an aqueous core surrounded by one or more outer lipid layers, and release their contents by interacting with the targeted cells through adsorption, endocytosis, lipid exchange, or fusion. Liposomal delivery is a means to modify the pharmacokinetic and pharmacodynamic properties of drugs with the objective of increasing efficacy and mitigating any potential side effects of drugs by enabling the delivery and targeting of the drug to the target site.

Liposomal delivery systems are an accepted, proven, and commercially viable strategy for the formulation of pharmaceuticals for clinical use. These lipid-based delivery systems are employed to improve tumour targeting, modulate the pharmacokinetics of the active agent and enhance its stability following administration. Therapeutic activity may be improved by modulating drug exposure and accumulation (controlled release) in the region where the target cancer cells are located
