CENTER FOR DRUG EVALUATION AND RESEARCH APPLICATION NUMBER: 204640Orig1s000 MEDICAL REVIEW(S) ADDENDUM TO MEDICAL OFFICER REVIEW Division of Pulmonary, Allergy, and Rheumatology Products (HFD-570) APPLICATION: NDA 204640 TRADE NAME: Adrenalin 30 mL vials APPLICANT/SPONSOR: JHP Pharmaceuticals, LLC USAN NAME: Epinephrine injection solution, USP, MEDICAL OFFICER: Peter Starke, MD 1 mg/mL (1:1000), 30 mL vials TEAM LEADER: Janet Maynard, MD CATEGORY: Non-selective alpha and beta adrenergic agonist (catecholamine) DATE: December 12, 2013 ROUTE: SC or IM SUBMISSIONS REVIEWED IN THIS DOCUMENT Document Date CDER Stamp Date Submission Comments Sept. 14, 2012 Sept. 14, 2012 N-000, SD-1 Original NDA submission for NDA 204-640, split from NDA 204-200 August 2, 2013 August 2, 2013 SD-2 PDUFA fee paid, NDA 204-640 reopened November 25, 2013 November 25, 2013 Medical Officer review of NDA 204640 REVIEW SUMMARY: This is an addendum to my clinical review dated November 25, 2013, for a 505(b)(2) application submitted by JHP Pharmaceuticals for the use of the currently marketed but unapproved 30 mL multiple- dose vial presentation of Adrenalin® (epinephrine injection, USP), 1mg/mL (1:1000), for the emergency treatment of allergic reactions (Type 1), including anaphylaxis [‘anaphylaxis’]. This application relies on the Agency’s previous findings of efficacy and safety for EpiPen for the treatment of anaphylaxis, and also cross-references to the approved 1 mL single-use vial Adrenalin product, which was approved on December 7, 2012. My original review noted the presence of chlorobutanol in the 30 mL vial presentation (which is not in the 1 mL vial presentation), stating that it does not affect the risk/benefit assessment for this presentation for indication of anaphylaxis, which remains favorable. It went on to note that chlorobutanol is also present in Twinject, an approved epinephrine auto-injector, thereby erroneously implying that this application relied in part on the Agency’s previous findings for the Twinject application. However, that is not the case. The review neglected to note that chlorobutanol is found in multiple other drug products, (b) and that the safety of chlorobutanol at (4) % in the proposed product is based on its listing on FDA’s inactive ingredient list: http://www.accessdata.fda.gov/scripts/cder/IIG/index.cfm. On this basis, the presence of chlorobutanol in this product is acceptable from a clinical perspective.
