Sanofi and its top-selling Lantus may have bought some time last month with a legal wrench in Eli Lilly's spokes, but now Merck has bulldozed its way into the conversation with plans to kick off late-stage studies for its own knockoff of the blockbuster drug, further complicating an already heated fight.
Sanofi's got the top-selling diabetes drug in the world right now, and it intends to keep it that way. The French drugmaker is suing Eli Lilly over infringement claims on four of the patents for its Lantus insulin product, which is set to lose protection next February.
You can scratch Eli Lilly's copycat version of Lantus off its short list of near-term approval prospects. Sanofi says it has filed a lawsuit against Lilly claiming that the pharma rival infringed four of its patents, which is likely to delay any launch until the middle of 2016.
Lantus is the best-selling diabetes drug in the world right now and the top-selling drug for Sanofi. But the drug goes off patent in 2015, so the French drugmaker is coming on strong with its Lantus successor, known as U300.
Sanofi has peeled back the cover on another chapter of Phase III data for U300, advancing its case that its next-gen diabetes therapy can be safer and just as effective as its blockbuster Lantus as it sets the stage for a regulatory pitch next year. But analysts may be left wondering if the long-acting insulin can successfully beat back rivals with a better set of data.
