FDA Law Blog In Generic PRECEDEX Litigiation, Hospira Wins Temporary Restraining Order; Court Orders Recall of Generics, then Backtracks

The pace of litigation concerning FDA’s approval of generic versions of Hospira, Inc.’s (“Hospira’s”) PRECEDEX (dexmedetomidine HCl) Injection, 100 mcg (base)/mL packaged in 200 mcg(base)/2 mL single-dose vials, has been anything but sedate.  On the morning of August 18, 2014, there was no sign of the controversy that would erupt later that day after FDA issued its long-awaited Letter Decision addressing issues raised in the Agency’s January 15, 2014 “Dear NDA/ANDA Applicant” letter (Docket No. FDA-2014-N-0087) concerning approval of generic PRECEDEX.
As we reported earlier this week, FDA ruled that ANDA sponsors could omit (i.e., carve out) from their generic drug labeling information protected by U.S. Patent No. 6,716,867 (“the ‘867 patent”).  The ‘867 patent is currently listed in the Orange Book for PRECEDEX with a “U-1472” patent use code defined as: “INTENSIVE CARE UNIT SEDATION, INCLUDING SEDATION OF NON-INTUBATED PATIENTS PRIOR TO AND/OR DURING SURGICAL AND OTHER PROCEDURES.”  (The ‘867 patent was previously listed in the Orange Book with a “U-572” patent use code defined as “INTENSIVE CARE UNIT SEDATION.”)
