TNF antagonists such as soluble p75 receptor constructs and anti-TNF monocl
onal antibodies are both currently licensed therapies for the treatment of
rheumatoid arthritis (RA). Based on experimental studies in animals and the
presence of elevated TNF levels in patients, there is also a strong ration
ale for TNF antagonism to be employed in asthma and COPD. In particular, TN
F seems to play an important role in determining the severity of asthma. TN
F antagonism might therefore be of particular interest for the treatment of
severe persistent asthma as well as acute severe exacerbations It might al
so constitute a novel anti-inflammatory therapy to control disease progress
ion in COPD.
