Data Indicate Dual Modes of Action and Synergy with Chemotherapy

DALLAS, Oct. 2 /PRNewswire-FirstCall/ -- Access Pharmaceuticals, Inc. (OTC Bulletin Board: ACCP) presented data this week from preclinical studies on Angiolix showing that by blocking lactadherin, Angiolix has both an anti-angiogenic effect as well as a direct anti-proliferative effect on tumors themselves. In preclinical models of human breast cancer (MX-1), Angiolix had a significant anti-cancer effect in vivo; this effect was enhanced when Angiolix was given in combination with conventional chemotherapy for breast cancer. The studies were conducted at Imperial College London and presented at the International Conference titled "Realizing the Commercial Potential of Therapeutic Antibodies," held in London, UK.

"We are delighted with these results which demonstrate the substantial anti-cancer effect of Angiolix, which we feel is comparable to Avastin yet achieved through a different and potentially complementary mechanism of action," stated Jeffrey B. Davis, President & CEO. "As stated previously, Access is actively seeking potential partners for the further clinical development of Angiolix."

"Angiolix is highly tumor specific," continued Agamemnon Epenetos, Chief Scientific Officer, Europe, "because the target lactadherin is primarily found in tumors and not in normal tissues. Other targets, such as VEGF, are present in many normal tissues; the blocking of VEGF may contribute to side effects such as high blood pressure and bleeding episodes, for example. Angiolix appears to be a more tumor selective anti-angiogenesis monoclonal antibody, with the benefit of having anti-proliferative activity."

Access is continuing to conduct pre-clinical studies at Imperial College London to more fully define the safety and efficacy profile of Angiolix.
