The deal for SmartCells Inc. would exceed $500 million if various milestones for development, regulatory approval and sales are met, the person said. It's the latest in a string of biotech purchases by major drug makers looking to replace aging blockbuster drugs.
SmartCells, of Beverly, Mass., is developing a form of insulin that aims to address a difficult aspect of treatment: the need to constantly monitor blood-sugar levels and adjust insulin levels accordingly. Usually several times a day, insulin-dependent patients must stick themselves to check their blood sugar and then inject themselves with insulin.
The new approach under development would require as few as one injection a day, with a new form of "glucose-responsive" insulin that would adjust throughout the day to changing blood-sugar levels. This "Smart Insulin," first developed in a Massachusetts Institute of Technology laboratory, hasn't yet been tested in humans, but SmartCells has said the method has shown promise in preclinical testing.
