PF-03893787 is potent and selective histamine H4 receptor (H4R) antagonist. It has comparable binding affinity to the human histamine H3 receptor. PF-03893787 was found to have significant affinity for the hERG channel. Novartis initiates a phase II extension trial in Atopic dermatitis. Studies exploring the utility of PF-3893787 in patients would be reported in due course, being the potential indications of asthma, pruritus, inflammatory skin diseases and pain, among others.
