Therapeutics NV submitted on 26 January 2016 an application for a marketing authorisation to the European Medicines Agency (The Agency) for GALLIPRANT, through the centralised procedure under Article 3(2)(a) of Regulation (EC) No 726/2004 (optional scope). The eligibility to the centralised procedure was agreed upon by the CVMP on 7 May 2015 as GALLIPRANT contains a new active substance (grapiprant) which was not authorised as a veterinary medicinal product in the Union on the date of entry into force of Regulation (EC) No 726/2004. The applicant applied for the following indication: For the treatment of pain and inflammation associated with osteoarthritis in dogs. The active substance in GALLIPRANT is grapiprant, a non-steroidal, non-cyclooxygenase inhibiting anti- inflammatory drug in the piprant class. Grapiprant is a selective antagonist of the prostaglandin E2 EP4 receptor, resulting in a reduction of pain and inflammation. The target species is dog. GALLIPRANT is presented in tablets of 20, 60 or 100 mg of grapiprant in a bottle containing 7 or 30 tablets. The applicant (Aratana Therapeutics NV) is registered as an SME pursuant to the definition set out in Commission Recommendation 2003/361/EC; however, the applicant out-licensed their application for GALLIPRANT to Elanco on 22 April 2016. The rapporteur appointed is Keith Baptiste and the co-rapporteur is Bruno Urbain. The dossier has been submitted in line with the requirements for submissions under Article 12(3) of Directive 2001/82/EC – full application. On 9 November 2017, the CVMP adopted an opinion and CVMP assessment report.
