Discontinued drugs for pulmonary, allergy, gastrointestinal, arthritis (2012)

Various compounds are developed to interfere with pathogenic pathways involved in inflammation processes. Some of them are able to enter the clinical development for different diseases with a common pathogenic denominator such as, for example, rheumatoid arthritis and chronic obstructive pulmonary disease (COPD), based on the preclinical evidence, but not all these molecules prove to be efficacious while tested in different phases of clinical development.

This review discusses about the drugs that were discontinued from further development for pulmonary, allergy, gastrointestinal and arthritis diseases

Most of the drugs discontinued during 2012 were compounds with anti-inflammatory activity which were mostly designed to treat arthritis/rheumatoid arthritis. Some of these molecules were also intended for COPD. Many of them failed the late phases of the clinical development.
