Phase I/II Study in Severe COPD Patients
Study #3: Sodium Pyruvate/SaO2 Pilot Study in Subjects with COPD (Dr. John Votto, Hospital for Special Care and the University of Connecticut Health Center, and Roger S. Thrall, PhD. Hospital for Special Care, New Britain, Connecticut).
The effect of the inhalation of a single dose of sodium pyruvate (0.5mM and 5.0mM) or placebo (0.9% sodium chloride) was studied in a double-blinded protocol on five patients. Each patient inhaled all three solutions at different time points in a blinded manner.
The inhalation of 0.5mM sodium pyruvate decreased Nitric Oxide (NO) levels by -35.87 % in 80% of the patients, while the 5.0mM concentration of sodium pyruvate increased NO levels by +19.5 in 100% of the patients producing a statically significant number. Inhalation of saline increased NO in 40% of the patients, and decreased NO in 60% of the patients averaging a decrease in NO. Figure 5 |
