Access Pharmaceuticals Announces Positive Top-Line Data From MuGard™ Phase IV Clinical Trial In Oral Mucositis Patients Presented At MASCC/ISOO 2013 Symposium

DALLAS and NEW YORK, June 27, 2013 /PRNewswire/ -- ACCESS PHARMACEUTICALS, INC. (OTCBB: ACCP), an emerging biopharmaceutical company, announced that Dr. Ron R. Allison of Carolina Radiation Medicine, Greenville, NC, presented top-line results today from a phase IV clinical trial evaluating MuGard™ Mucoadhesive Oral Wound Rinse at the MASCC/ISOO International Symposium on Supportive Care in Cancer in Berlin, Germany. The prospective, randomized, multi-center, double-blind, placebo-controlled study evaluated the efficacy of MuGard in controlling symptoms caused by oral mucositis in 120 patients receiving chemoradiation therapy for the treatment of cancers of the head and neck.

The presentation, entitled "The Multi-Institutional, Randomized, Double-Blind, Placebo-Controlled Trial to Assess the Efficacy of MuGard in Mitigating Oral Mucositis (OM) in Chemoradiation-Treated Head and Neck Cancer Patients" summarized top-line data on 78 patients who were enrolled in the study for a minimum of two weeks. The patients were randomized 1:1 to receive either MuGard or placebo (a saline-bicarbonate rinse), with 37 evaluable MuGard patients and 41 evaluable placebo patients summarized in this analysis.

The primary endpoint of the study was the reduction of symptoms of oral mucositis, as determined by the area-under-the-curve (AUC) of Oral Mucositis Daily Questionaire (OMDQ) Mouth and Throat Soreness (MTS) question 2, a validated mucositis assessment tool. MuGard met the primary study endpoint, with patients receiving MuGard experiencing a statistically significant reduction versus placebo in mouth and throat soreness.  In addition, fewer patients receiving MuGard had ulcerative OM (WHO score >/= 2) at the end of radiation therapy.

"For this head and neck cancer population, the debilitating side effect of oral mucositis remains one of our most significant clinical challenges. The benefits of MuGard shown in these results are critically important, both clinically and from a patient quality-of-life perspective," stated Dr. Ron R. Allison, a principal investigator in the MuGard trial, Carolina Radiation Medicine, Greenville, NC.  "MuGard helps patients manage their mucositis during these tough treatment regimens."

"Oral mucositis is a significant medical need for this population and these study results provide strong evidence of MuGard's effectiveness in managing the mouth and throat soreness associated with it," stated expert on cancer-treatment mucosal toxicities, Stephen T. Sonis, DMD, DMSc, Clinical Professor of Oral Medicine at Harvard and consultant to Clinical Assistance Programs for this trial.

About Oral Mucositis

Oral mucositis ("OM") is a debilitating side effect of some radiation and chemotherapy cancer treatments, characterized by sores and ulcers in the mouth and throat that make swallowing difficult or impossible. It is estimated that 97% of patients receiving radiation for head and neck cancer, 70% of patients receiving stem cell transplantation and up to 40% of patients receiving conventional chemotherapy develop oral mucositis. The NIH estimates that there are 400,000 patients diagnosed with OM in the US annually, but OM is often under-diagnosed and the population at risk is significantly higher.


MASCC, or the Multinational Association of Supportive Care in Cancer, is the leading international organization dedicated to the research and education in all aspects of supportive care for patients with cancer.  It joined forces with the International Society of Oral Oncology (ISOO) in 1998, and its members represent over sixty countries. The MASCC/ISOO membership includes oncology medical, surgical, and radiology physicians, nurses, dentists, dental hygienists, pharmacists and representatives from industry and non-profit sectors. Symposia are convened annually to share the most recent research in supportive care from throughout the world.
