PharmaGap Reports That GAP-107B8 Showed Strong and Consistent Anti-Cancer Activity in a Wide Range of Cancers in NCI Test
Last Update: 10/27/2009 8:30:49 AM

OTTAWA, ONTARIO, Oct 27, 2009 (Marketwire via COMTEX) -- PharmaGap Inc. (GAP)(PHRG.F) ("PharmaGap" or "the Company") is pleased to announce highly positive results from the United States National Cancer Institute ("NCI") 5-dose in vitro anti-cancer screen of PharmaGap drug GAP-107B8. These results confirm and extend results announced in August from the single-dose study and provide definitive independent validation of GAP-107B8 as an active pharmaceutical ingredient against a wide range of cancers.

GAP-107B8 is a novel peptide protein kinase inhibitor that was designed to specifically target molecular signaling pathways in cancer cells. Targeted therapies are designed to target cancer cells while sparing surrounding normal, healthy, cells, thus causing less toxic effects than many standard chemotherapeutic agents currently in use.

Within a dose concentration range of 10 to 100 micromolar (u M), GAP-107B8 caused 100% growth inhibition (measured against cancer cell growth in untreated groups) in 51 of 56 cancer cell lines and caused at least 50% cancer cell death (measured against the number of cancer cells at the beginning of the test period) in 29 of 56 cancer cell lines.

The standard NCI test methodology generates three values that are used to measure the drug compound's activity against the cancer cell-line panel. These are: the GI50, the dose that causes an average 50% growth inhibition in the cell lines; the TGI, the dose that causes an average 100% growth inhibition in the cell lines; and the LC50, the dose that causes an average 50% cell death in the cell lines. For GAP-107B8, the GI50 was determined to be 23 u M, the TGI was 51 u M, and the LC50 was 89 u M. These data provide a very clear range of focus for all future studies.

These results provided a large amount of data, from the NCI testing which will be used by the Company to select specific cancer types and to determine an optimum dosing range for future animal studies and subsequent clinical trials. Based on these and prior results, the Company will be focusing its immediate development program on ovarian cancer and melanoma. The first of these animal studies is currently underway at the Ottawa Hospital Research Institute ("OHRI") in ovarian cancer. Further testing of GAP-107B8 on melanoma is about to commence under the guidance of Dr. Gary Schwartz at Memorial Sloan Kettering Cancer Center in New York. GAP-107B8 showed a strong effect in both melanoma and ovarian cancers in both single-dose and 5-dose testing at the NCI. In addition, the Company and NCI staff will meet in late November to discuss these results and ways in which the NCI may participate in various aspects of the development program for GAP-107B8.

The results across such a wide range of cancer cell lines, including a number which are known to be resistant to standard chemotherapy, indicate that GAP-107B8 has the potential to become a new cancer drug with less toxic side effects than common chemotherapeutic regimens.

Robert McInnis, President of the Company, stated "We are very pleased with the extent of activity in the NCI panel, as this activity against all cell lines provides a wide range of development opportunities for us, and provides us with additional support for a focus on ovarian cancer and melanoma. Our objective of the testing at the NCI - independent and verifiable validation of activity - has been fully realized. Over the past 12 months we have made significant progress in moving our lead drug to clinical trials: generating quality- controlled gram-scale production of the compound; achieving verifiable independent validation of compound activity at both the NCI and here in Ottawa at the OHRI; and programs underway in the area of bioassay development, understanding of signalling pathways involved, and continued testing programs at Memorial Sloan Kettering. This progress is very encouraging to me and to our team. Most importantly, results so far indicate a potential for new hope for the future of patients suffering from several types of cancer".

About The National Cancer Institute

The National Cancer Institute (NCI), located in Bethesda, MD is an institute of the National Institutes of Health, the primary U.S. Federal Agency for conducting and supporting medical research. The NCI has a mandate to select and screen novel drug compounds that could potentially make a material difference in the "war against cancer". Selection to the NCI screening program is through a competitive application process. Details on the NCI's compound screening program can be found at http://dtp.nci.nih.gov/ .
