Access Pharmaceuticals Announces Two Poster Presentations Reporting Significant Preclinical Data on ProLindac at the AACR-NCI-EORTC 'Molecular Targets and Cancer Therapeutics' Conference

DALLAS, October 29, 2007 /PRNewswire-FirstCall/ -- Access Pharmaceuticals, Inc. announced today that two posters describing significant preclinical studies performed by Access collaborators at two prominent institutes in France, were presented last week at the joint symposium of the American Association for Cancer Research (AACR), National Cancer Institute (NCI) and European Organization for Research and Treatment of Cancer (EORTC) entitled "International Conference Molecular Targets and Cancer Therapeutics: Discovery, Biology, and Clinical Applications One poster provides results of additional studies of the mechanism of ProLindac's anticancer activity, while the second poster demonstrates the potential benefits for cancer therapy of combining ProLindac with other anticancer agents.

"These studies, which are a continuation of work presented at the AACR annual meeting earlier this year, provide further support to our belief that ProLindac has the potential to become an important tool in the fight against cancer" stated David P. Nowotnik, Access' Senior Vice President Research and Development. "One poster shows that the cytotoxicity of ProLindac in a panel of cancer cell lines is greater than that found for either oxaliplatin or cisplatin, while the second poster demonstrates that combinations of ProLindac with certain other anticancer compounds produces cytotoxic effects which are greater than is produced by use of the drugs individually."

In addition, the studies reaffirmed that ProLindac becomes more effective in the lowered pH environment of many tumors by showing that the formation of cancer-killing platinum-DNA adducts increases in tumor cells which are exposed to lower pH conditions. Exposure to ProLindac also resulted in tumor cell cycle arrest at a phase of the cycle where the tumor cell is more susceptible to damage. These effects can lead to programmed death (apoptosis) of the tumor cell. A synergistic effect of ProLindac was found with such well-established anticancer compounds as 5-fluorouracil (5-FU) and gemcitabine, leading the authors to recommend that further investigation of ProLindac's use with other cancer drugs in clinical trials is warranted and lay the groundwork for the ProLindac combination clinical studies which Access is planning beginning in 2008.
