PALO ALTO, CA--(Marketwire - August 07, 2008) - The Stanford University Center on Longevity and the U.S. Department of Veterans Affairs Palo Alto Health Care System (VAPAHCS) today announced positive data from their 10-week study of the Cyclic Variations in Altitude Conditioning™ (CVAC™) process, CVAC Systems Inc.'s new modality being researched for insulin resistance and diabetes. The blinded, controlled clinical trial, which exposed subjects to the CVAC process for 40 minutes, three times a week for 10 weeks, found that the subject group receiving active CVAC exposure demonstrated a significant reduction in fasting blood glucose and a significant decrease in blood glucose during an oral glucose tolerance test (OGTT) following the 10 weeks of exposure. There was no significant change in the control group. No significant safety concerns were observed during the study.
