New treatment gives hope for pulmonary fibrosis patients

21.05.2008
Patients with idiopathic pulmonary fibrosis (IPF) may have a new treatment option, according to researchers in Japan.

In a Phase III, double-blind, placebo-controlled clinical trial, the investigators discovered that a daily dose of pirfenidone could slow the progression of IPF, reducing the loss of lung capacity. The results will be announced at the American Thoracic Society’s 2008 International Conference in Toronto on Tuesday, May 20.

“The most common treatment for IPF is anti-inflammatory agents such as steroids,” said lead researcher Takashi Ogura, M.D., of Kanagawa Cardiovascular and Respiratory Center in Yokohama, Japan. “However our study confirmed that pirfenidone, the main action of which is thought to be antifibrotic, achieved a therapeutic effect on IPF. I expect that our study will serve as a guide to develop a new therapy for IPF in the future.”

The researchers recruited a total of 275 Japanese patients with mild to moderate IPF and randomized them to a high dose pirfenidone (1,800 mg/day) group, a low dose pirfenidone group (1,200 mg/day) and a placebo group. They measured lung capacity (vital capacity or VC) and progression-free survival, defined as a period without death or a greater than 10 percent decrease in VC, to determine the effectiveness of the regimens.

At the end of one year, they found that patients who had been randomized to the high dose regimen had significantly lower loss of VC than the placebo group. Furthermore, pirfenidone slowed the overall deterioration of IPF compared to the placebo.

“Taken altogether, our study demonstrated positive clinical effects of pirfenidone that suppresses the progress of IPF and potentially contributes to improving the outcomes of patients with IPF,” said Dr. Ogura.

Pirfenidone represents new hope, not only for IPF patients who currently have no curative treatment options, but because it is thought to be an antifibrotic agent, it may be able to treat other fibrotic lung diseases, such as interstitial pneumonia with collagen vascular disease and extrapulmonary fibrosis.

“We will continue the follow-up of the patient cohort included in this study to identify whether pirfenidone can contribute to prolonged survival in patients with IPF,” said Dr. Ogura. “Other clinical studies of pirfenidone are also being conducted in the U.S. and Europe, and we hope that our results will be replicated there.”

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
