Access Pharmaceuticals Announces Presentation on ProLindac(TM) Phase 2 Study

DALLAS, Oct. 24 /PRNewswire-FirstCall/ -- ACCESS PHARMACEUTICALS, INC. announced today that a poster providing early evidence of efficacy from the ProLindac(TM) Phase 2 Clinical Study in Recurrent Ovarian Cancer was presented yesterday 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.”

The presentation reported initial data from an ongoing ovarian cancer study utilizing ProLindac at two and three week intervals. Significantly, there was a reduction of the Ca125 biomarker in five of the six patients in the cohort receiving the higher dose of ProLindac on a once every three week dosing schedule. The Ca125 biomarker has been demonstrated to be a reliable indicator of the clinical progression of ovarian cancer, and it has been shown that a reduction in this biomarker provides an early sign that a treatment regimen is effective in combating ovarian cancer. Dose escalation in the trial is continuing. At the reported doses, toxic effects observed were generally mild and ProLindac displayed none of the acute neurotoxicity associated with other approved DACH platinum compounds.

“This early result provides us with a very positive indication that ProLindac is capable of effecting clinically meaningful stabilization of patients with ovarian cancer,” stated Dr. Esteban Cvitkovic, Access’ Vice-Chairman (Europe) and Senior Director, Oncology Clinical R&D. “Moreover, there was no indication of nephrotoxicity in any patient, and the only indication of neurotoxicity was a delayed, slight increase in baseline in two patients with such baseline conditions of neurotoxicity. These data allow us to continue dose escalation in order to establish a higher therapeutic index. It will also allow us to expand the study into a ProLindac combination drug trial to fully explore the potential of this very promising agent.”

“We are very pleased by the activity and safety of ProLindac in the early cohorts of the ovarian cancer trial,” added Stephen R. Seiler Access’ President and CEO, “Even as we continue dose escalation in the current trial, existing results have given us sufficient confidence to move forward with the execution of additional development plans for ProLindac and we have already commenced manufacturing drug supply for several further clinical trials, including combination trials, which we plan to commence beginning next year.”

The ProLindac Phase 2 clinical study in recurrent ovarian cancer is continuing at eleven leading oncology centers in France, and it is anticipated that further results will be reported on the study at leading oncology conferences in 2008. Access anticipates the initiation of additional Phase 2 studies in other indications during the first quarter of 2008.
