Napo Presents at ISPOR Meeting ...( SOUTH SAN FRANCISCO Calif. May 12...),Health

SOUTH SAN FRANCISCO, Calif., May 12 /PRNewswire-FirstCall/ -- Napo Pharmaceuticals, Inc., (LSE: NAPL and NAPU), announces that it presented a poster in collaboration with QualityMetric, Inc. describing the development of a patient reported outcomes questionnaire focused on the Health-Related Quality of Life (HR-QoL) aspects of chronic diarrhea in persons living with HIV/AIDS at the 13th International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Annual Meeting in Toronto, Ontario, May 3 through 7, 2008.

Using classic and modern psychometric methods, a single scale comprised of 9 survey questions covering two HR-QoL content areas was developed. The survey questions showed consistency across gender, race and education level, demonstrated a statistically significant greater negative impact on HR-QoL with more frequent and more severe diarrhea symptoms.

Cathy Olufs, President, AIDS Activist Treatment Coalition (ATAC) stated, "We are fortunate to currently have a wide choice of HIV medications and combinations. This makes understanding medication side effects and their impact on a patient's quality of life more important than ever. Controlling side effects such as diarrhea can help give patients access to the full armamentarium of anti-retroviral drugs. We are pleased to see Napo taking the initiative to develop this new instrument to measure health-related quality of life as affected by diarrhea."
