Vyvanse(R) Patents Found to Be Infringed and Valid

Vyvanse® Patents Found to Be Infringed and Valid by U.S. District Court Lexington, Mass., USA - June 25, 2014 - Shire plc (LSE: SHP, NASDAQ: SHPG)announces that Judge Stanley R. Chesler of the U.S. District Court for theDistrict of New Jersey granted Shire's summary judgment motion in a patentinfringement lawsuit, holding that certain claims of the patents protectingVyvanse® (lisdexamfetamine dimesylate) were both infringed and valid. The ruling prevents the five pharmaceutical manufacturers (the ANDA-Defendants) who have filed Abbreviated New Drug Applications (ANDAs) fromlaunching generic versions of Vyvanse until the earlier of either a successfulappeal to the U.S. Court of Appeals for the Federal Circuit, or the expirationof these patents in 2023. To appeal successfully, the ANDA-Defendants mustoverturn the Court's rulings for each of the 18 patent claims. The Court's summary judgment ruling concerning Shire's motion included 18patent claims from four of the FDA Orange Book-listed patents for Vyvanse,which cover Vyvanse's active ingredient, the lisdexamfetamine dimesylatecompound, and a method of using lisdexamfetamine dimesylate for the treatmentof ADHD. "We are extremely pleased with the Court's ruling, which affirms Shire's beliefthat it has strong patents protecting Vyvanse," said Flemming Ornskov, MD,Chief Executive Officer for Shire. Shire's Vyvanse patents expire in 2023 but Shire recently announced that it hasagreed to a Written Request by the Food and Drug Administration to conductpediatric clinical studies to investigate the potential use of Vyvanse for thetreatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in preschool-agechildren, ages 4 to 5. Upon FDA confirmation of a timely submission and reviewof data that adheres to the requirements of the Written Request, Shire will beentitled to the benefits of the Best Pharmaceuticals for Children Act,including a six-month extension to the exclusivity afforded by Shire's patentsfor Vyvanse. Shire's lawsuit is against the five ANDA - Defendants that filed ANDAs with theU.S. Food and Drug Administration (FDA) seeking to market generic versions ofVyvanse, and their Active Pharmaceutical Ingredient (API) manufacturer oflisdexamfetamine dimesylate API. The ANDA-Defendants are Actavis LLC/ActavisElizabeth LLC; Amneal Pharmaceuticals, LLC; Mylan Pharmaceuticals Inc./MylanInc.; Roxane Laboratories Inc.; and Sandoz Inc. The API manufacturer andsupplier to each of the ANDA-Defendants is Johnson Matthey Inc./Johnson MattheyPharmaceutical Materials. This lawsuit includes all of the known ANDAs that arecurrently pending for Vyvanse. The Court found that "[t]here is no real dispute about the ANDA Defendants'direct infringement of the compound claims," Johnson Matthey "is liable forinducing the ANDA Defendants' direct infringement of the compound claims," and"the ANDA Defendants have induced infringement" of a claimed method of treatingADHD. As to validity, the Court found that "Defendants have not shown thatlisdexamfetamine was disclosed in the prior art" and "Defendants have failed topoint to evidence sufficient to persuade a reasonable jury that [prior artreference] AU '168 anticipates by disclosing lisdexamfetamine dimesylate," and"have failed to defeat the motion for summary judgment regarding invalidity dueto obviousness of the compound patents." Additionally, the Court found that"Defendants have not offered evidence sufficient to prove [method of treatingADHD] claim 4 of the '486 patent is invalid due to obviousness oranticipation." Shire's summary judgment motion did not include every patent claim in thelitigation and, accordingly, the Court's decision did not dispose of thelitigation in its entirety. In addition to Shire's motion, the Court also ruledon five summary judgment motions filed by the defendants. The Court's rulingsdenied API-supplier Johnson Matthey's motion to dismiss certain indirectinfringement claims, dismissed Shire's willful infringement claims, granteddefendants' motion concerning noninfringement of certain method of use claims,and denied defendants' two invalidity motions. At this point, the Court mustdecide whether to conduct a trial on the remaining patent claims, or allow thedefendants to immediately appeal this ruling to the Federal Circuit. Shiremaintains its belief that it has strong infringement claims against each of thesix defendants for the patent claims that were not included in Shire's motion,and strongly believes that the asserted patent claims are valid.
