The US Food and Drug Administration is facing another round of lawsuits over its marketing exclusivity decisions. Alvogen contends Teva forfeited its 180-day marketing exclusivity for a generic version of the opioid treatment Belbuca (buprenorphine buccal film). And Sandoz claims Sanofi’s multiple sclerosis drug Aubagio (teriflunomide) does not qualify for new chemical entity exclusivity.
