Australian Public Assessment Report for Ixekizumab Australian Public Assessment Report for Ixekizumab Proprietary Product Name: Taltz Sponsor: Eli Lilly Australia May 2017 Therapeutic Goods Administration About the Therapeutic Goods Administration (TGA) • The Therapeutic Goods Administration (TGA) is part of the Australian Government Department of Health and is responsible for regulating medicines and medical devices. • The TGA administers the Therapeutic Goods Act 1989 (the Act), applying a risk management approach designed to ensure therapeutic goods supplied in Australia meet acceptable standards of quality, safety and efficacy (performance) when necessary. • The work of the TGA is based on applying scientific and clinical expertise to decision- making, to ensure that the benefits to consumers outweigh any risks associated with the use of medicines and medical devices. • The TGA relies on the public, healthcare professionals and industry to report problems with medicines or medical devices. TGA investigates reports received by it to determine any necessary regulatory action. • To report a problem with a medicine or medical device, please see the information on the TGA website <https://www.tga.gov.au>. About AusPARs • An Australian Public Assessment Report (AusPAR) provides information about the evaluation of a prescription medicine and the considerations that led the TGA to approve or not approve a prescription medicine submission. • AusPARs are prepared and published by the TGA. • An AusPAR is prepared for submissions that relate to new chemical entities, generic medicines, major variations and extensions of indications. • An AusPAR is a static document; it provides information that relates to a submission at a particular point in time. • A new AusPAR will be developed to reflect changes to indications and/or major variations to a prescription medicine subject to evaluation by the TGA.

Email: [email protected] Received: 14 July 2015, Revised and Accepted: 24 August 2015 ABSTRACT Psoriasis is an autoimmune disease and further classed as a chronic inflammatory skin condition serving as a global burden. A moderate to severe psoriasis can be treated with conventional therapies. Less efficacy, poor patient compliance, and toxicity issues were the major problems associated with conventional therapies. The introduction of biologic therapy has a great impression on psoriatic treatment duration and enhanced quality of life in psoriasis patients. The new biologic therapies are tailor-made medications with the goal of more specific and effective treatment; less toxicity. The biologic therapy is aimed to target antigen presentation and co-stimulation, T-cell activation, and leukocyte adhesion; and pro-inflammatory cascade. They act as effective and safer substitute to traditional therapy. Secukinumab, certolizumab, itolizumab, golimumab, ustekinumab, adalimumab, infliximab etanercept, alefacept, etc. are the approved biologic with the global market. This review briefs about psoriasis pathogenesis, traditional treatments, and biologic therapies potential. Keywords: Psoriasis, Biologic, Non-biologic treatment. INTRODUCTION migration, potentiation of Th1 type of response, angiogenesis, and epidermal hyperplasia [7]. Psoriasis is an autoimmune disease and further classed as a chronic inflammatory skin condition with prevalence ranging 1-3% in the TNF- is plays vital role in the pathogenesis of psoriasis.

  • Novel Psoriasis Therapies and Patient Outcomes, Part 2: Biologic Treatments
    Novel Psoriasis Therapies and Patient Outcomes, Part 2: Biologic Treatments Meghan A. Feely, MD; Barry L. Smith, MD; Jeffrey M. Weinberg, MD Practice Points Novel biologic treatments promise exciting new therapeutic avenues for psoriasis and psoriatic arthritis (PsA). Although biologics currently in use for treatment of psoriasis and PsA are in the form of tumor necrosis factor α inhibitors, other drugs in phase 2 through phase 4 clinical trials aim to target alternative pathways underlying the pathogenesis of these disorders, including IL-12/IL-23 inhibition, IL-17 inhibition, inhibition of T-cell activation in antigen-presenting cells, regulatory T-cell activation, toll-like receptor inhibition, and granulocyte-macrophage colony-stimulating factor inhibition. New approaches to the management of psoriasis and PsA offer patientscopy hope for more targeted treat- ment regimens. not Biologic treatments have revolutionized the man- second in a 3-part series on treatments presently agement of psoriasis and psoriatic arthritis (PsA).Do in the pipeline for the management of psoriasis Anti–tumor necrosis factor (TNF) α monoclo- and PsA including topical agents, biologic treat- nal antibodies presently are approved by the ments, and systemic therapies in phase 2 through US Food and Drug Administration (FDA) for treat- phase 4 clinical trials as well as agents that are ment of these conditions.

The FDA background package often contains assessments and/or conclusions and recommendations written by individual FDA reviewers. Such conclusions and recommendations do not necessarily represent the final position of the individual reviewers, nor do they necessarily represent the final position of the Review Division or Office. We have brought Siliq (brodalumab) injection, 210 mg/1.5 ml to this Advisory Committee in order to gain the Committee’s insights and opinions. The background package may not include all issues relevant to the final regulatory recommendation, but instead is intended to focus on issues identified by the Agency for discussion by the advisory committee. The FDA will not issue a final determination on the issues at hand until input from the advisory committee process has been considered and all reviews have been finalized. The final determination may be affected by issues not discussed at the advisory committee meeting.
