PARI Aerosol Research Institute's eFlow In Cystic Fibrosis Clinical Trial Of L-arginine

11/29/2006 12:12:00 PM

MONTEREY, Calif., Nov. 29 /PRNewswire/ -- PARI Aerosol Research Institute and The Hospital for Sick Children (SickKids) in Toronto are studying an inhaled L-arginine formulation delivered by PARI's eFlow to treat cystic fibrosis.

Dr. Felix Ratjen, chief of Respiratory Medicine and senior scientist in Physiology & Experimental Medicine at SickKids, is conducting the multi- centre, double-blind, randomized, placebo-controlled trial. The study evaluates the safety, tolerability, and durability of response to L-arginine therapy in cystic fibrosis (CF) patients.

In CF patients, nitric oxide formation and nitric oxide synthases, the enzymes responsible for the synthesis of nitric oxide, are decreased, which is believed to impair lung function. Lab studies have shown that adding L-arginine, the precursor of enzymatic nitric oxide formation, relaxes the trachea. The hope is that lung function in CF patients can be improved by increasing L-arginine concentrations.

"We are currently working on a variety of clinical trials aimed at helping cystic fibrosis sufferers live healthier and longer. The lab work conducted to date on L-arginine is very promising, and our hope is that this will lead to a new medication that will improve lives," said Dr. Martin Knoch, Managing Director of PARI. "SickKids is a wonderful research and clinical hospital, and we are pleased that we can work so closely together on this study."

Cystic fibrosis is an inherited chronic disease that affects the lungs and digestive systems of about 70,000 children and adults worldwide. Patients have a defective gene that causes the body to produce unusually thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections. CF also obstructs the pancreas and stops natural enzymes from helping the body break down and absorb food. With the advancements in medical care over the last decades, the median age of survival has increased to 37. Additional information is available from the Cystic Fibrosis Foundation at

About eFlow

eFlow, an electronic, portable nebulizer, enables extremely efficient aerosolization of liquid medications via a vibrating, perforated membrane. Compared to other nebulizer systems, eFlow can produce aerosols with a very high density of active drug, a precisely defined droplet size, and a high proportion of respirable droplets delivered in the shortest possible period of time. Combined with its silent mode of operation, small size (it fits in the palm of your hand), light weight, and battery use, eFlow helps reduce the burden of taking daily inhaled treatments.
