<strong>Shire</strong> plc <strong>Annual</strong> <strong>Report</strong> and Accounts 20099Patents and market exclusivityThe loss or expiration of patent protection or regulatory exclusivity with respect to any of the Group’s major products could have a material adverseeffect on the Group’s revenues, financial condition and results of operations as generic manufacturers may enter the market. Generic manufacturersoften do not need to complete extensive clinical studies when they seek registration of a copy product and accordingly, they are generally able to sellthe Group’s drugs at a much lower price.As expected, in 2009 Teva Pharmaceutical Industries Ltd (‘Teva’) and Impax Laboratories, Inc. (‘Impax’) commenced commercial shipments of theirauthorized generic versions of ADDERALL XR. During the year to December 31, 2009 the Group’s sales of ADDERALL XR declined by 43% to$626.5 million, representing 21% of total revenues in 2009 (2008: 36%). In October 2005 the Group filed a Citizen Petition with the FDA requesting thatthe FDA require more rigorous bioequivalence testing or additional clinical testing for generic or follow-on drug products that reference ADDERALL XRbefore they can be approved. The Group received correspondence from the FDA in April 2006 stating that, due to the complex issues raised, whichrequire extensive review and analysis by the FDA’s officials, a decision cannot yet be reached by the FDA. The FDA has not yet reached a decisionon this Citizen Petition and did not provide any guidance as to when that decision may be reached.<strong>Shire</strong> is engaged in various legal proceedings with generic manufacturers with respect to its FOSRENOL and CARBATROL patents, as well as thepatents for certain other products. During 2009 <strong>Shire</strong> settled certain legal proceedings relating to ADDERALL XR and CARBATROL. <strong>Shire</strong> has alsointervened in a lawsuit brought by Actavis Elizabeth LLC against the FDA concerning FDA’s decision to grant VYVANSE new chemical entity regulatoryexclusivity. For more detail of current patent litigation, see Note 24 to the consolidated financial statements for further details.Products under developmentSPECIALTY PHARMACEUTICALSTreatments for ADHDVYVANSE for ADHD in EUVYVANSE for the treatment of ADHD in children aged six to 17 in the EU is in Phase 3 development. <strong>Shire</strong> anticipates submission of the regulatoryfiling for VYVANSE in Europe in 2011.INTUNIV for use in combination with other ADHD treatmentsPhase 3 trials in the US are ongoing to support the efficacy and safety of INTUNIV when combined with other approved ADHD treatments.Treatments for GI diseasesLIALDA for the maintenance of remission in ulcerative colitis in the USPhase 3 trials investigating the use of the product to maintain remission in patients who have ulcerative colitis were initiated in 2006 for the US marketand continued through 2009. The product was indicated for the maintenance of remission in patients who have ulcerative colitis on approval in the EU.LIALDA/MEZAVANT for the treatment of diverticulitisDiverticulosis is among the most common diseases in developed countries and manifests as weaknesses or out-pouches of the bowel wall primarilyin elderly populations. Approximately 15-20% of people with diverticulosis go on to develop diverticulitis which is an acute inflammation, infection andmicro or macro-perforation of these out-pouches. The current standard of care requires treatment with antibiotics and depending on the frequencyor severity of attacks, may require surgery. LIALDA/MEZAVANT is being investigated as a treatment to prevent recurrent attacks of diverticulitis.Phase 3 worldwide clinical trials investigating the use of the product for the treatment of diverticulitis were initiated in 2007 and are ongoing.Treatments for diseases in other therapeutic areasFOSRENOL for the treatment of pre-dialysis chronic kidney disease (‘CKD’)<strong>Shire</strong> is continuing to explore the regulatory pathway required to secure a label extension for FOSRENOL to treat hyperphosphataemia in pre-dialysisCKD in the US.JUVISTA for the improvement of scar appearanceRenovo initiated its first pivotal European Phase 3 trial in scar revision in the fourth quarter of 2008 to support the filing of a European regulatorydossier. If the outcome from Renovo’s multi-center, EU Phase 3 study is suitably positive, the data will be used to inform the strategy and designof <strong>Shire</strong>’s US development plan.VYVANSE for the treatment of non-ADHD indications in adults<strong>Shire</strong> is conducting Phase 2 pilot clinical trials to assess the efficacy and safety of VYVANSE as adjunctive therapy in depression, for the treatmentof negative symptoms and cognitive impairment in schizophrenia, and for the treatment of cognitive impairment in depression.SPD 535 for the treatment of arteriovenous grafts in hemodialysis patientsSPD 535 is in development as a novel molecule with platelet lowering ability and without phosphodiesterase type III inhibition. The initial proofof concept program will target prevention of thrombotic complications associated with arteriovenous grafts in hemodialysis patients. Phase 1development was initiated in the third quarter of 2009.Projects in pre-clinical developmentA number of additional projects are underway in the early stages of pre-clinical development for the Specialty Pharmaceuticals area, including potentialprograms leveraging Carrierwave technology primarily focused in the areas of pain and ADHD. More data on these programs is expected in the secondhalf of 2010.
