Monopar Breathes New Life Into AstraZeneca’s Wilson Disease Drug

Despite a successful Phase III study of ALXN-1840 for the inherited disorder that prevents the liver from filtering copper out of the body, the UK major's rare disease division Alexion pulled the plug on the program last summer.

It is not often that a big pharma is tapped by a small player for a deal but the markets have reacted well to Monopar Therapeutics’ move to license AstraZeneca’s late-stage Wilson’s disease drug and reunite its CEO with a drug he worked on a couple of decades ago.

Monopar has entered into an agreement with Alexion, AstraZeneca’s rare disease unit, for an exclusive worldwide license to ALXN-1840 (bis-choline tetrathiomolybdate) for Wilson, a rare and progressive genetic condition caused by variants in the ATP7B gene and characterized by a build-up of toxic copper levels in the liver, brain and other organs
