JNJ-7777120 was a drug being developed by Johnson & Johnson Pharmaceutical Research & Development which acts as a potent and selective antagonist at the histamine H4 receptor.[1] It has anti-inflammatory effects,[2] and has been demonstrated to be superior to traditional (H1) antihistamines in the treatment of pruritus (itching).[3] The drug was abandoned because of its short in vivo half-life and hypoadrenocorticism toxicity in rats and dogs, that prevented advancing it into clinical studies.[4]
