  Antivirals have been tested for effectiveness in the common cold; as of 2009, none had been both found effective and licensed for use. There are trials of the anti-viral drug pleconaril which shows promise against picornaviruses as well as trials of BTA-798. The oral form of pleconaril had safety issues and an aerosol form is being studied. The genomes of all known human rhinovirus strains have been sequenced.
