[Date of application] January 21, 2010 [Results of review] Based on the submitted data, the efficacy of the product in the treatment of psoriasis vulgaris and psoriatic arthritis in patients who have had an inadequate response to conventional therapy has been demonstrated and its safety is acceptable in view of its observed benefits. Serious adverse drug reactions such as infections may occur following administration of the product. Therefore, prior to the use of the product, the patient’s symptoms etc. should be monitored closely and the risks and benefits of the product should be weighed carefully. The risks of the product should be fully explained to the patient as well. It is necessary to closely monitor the course of the disease also after the initiation of treatment. After the market launch, a post-marketing surveillance study focusing on the occurrence of serious infections etc., covering all the patients treated with the product, and a long-term survey to follow the patients for the development of infections and malignancy etc. need to be conducted. As a result of its review, the Pharmaceuticals and Medical Devices Agency has concluded that the product may be approved for the indication and the dosage and administration as shown below, with the following conditions. [Indication] Treatment of the following diseases in patients who have had an inadequate response to conventional therapy: Psoriasis vulgaris and psoriatic arthritis [Dosage and administration] The usual initial adult dosage is 45 mg of Ustekinumab (Genetical Recombination) administered subcutaneously, followed 4 weeks later by a 45 mg dose, and then every 12 weeks thereafter. If the effect is insufficient, a dose of 90 mg may be used. [Conditions for approval] The applicant is required to: (1) Conduct a post-marketing drug use-results survey, which covers all the patients treated with the 5 product, until data from a certain number of patients will be accumulated, in order to collect data on the safety and efficacy of the product as soon as possible and to take necessary measures to ensure proper use of the product. (2) Conduct a large-scale post-marketing surveillance study to fully evaluate the safety of the product and to investigate the long-term safety of the product and the occurrence of infections etc. 6 Review Report (1) October 12, 2010 I.

These agents provide numerous benefits compared to traditional small molecule drugs, though their clinical use still requires optimization. The pharmacology of mAbs/ADCs is complex and because ADCs are comprised of multiple components, individual agent characteristics and patient variables can affect their disposition. To further improve the clinical use and rational development of these agents, it is imperative to comprehend the complex mechanisms employed by antibody-based agents in traversing numerous biological barriers and how agent/patient factors affect tumor delivery, toxicities, efficacy, and ultimately, biodistribution.

  • Advances in Immunosuppression for Renal Transplantation Antoine Durrbach, Helene Francois, Severine Beaudreuil, Antoine Jacquet and Bernard Charpentier
    REVIEWS Advances in immunosuppression for renal transplantation Antoine Durrbach, Helene Francois, Severine Beaudreuil, Antoine Jacquet and Bernard Charpentier Abstract | The development of immunosuppressants with minimal adverse and nephrotoxic effects is important to improve outcomes, such as acute and chronic antibody-mediated rejection, after organ transplantation. In addition, the application of expanded criteria for donors and transplantation in immunized patients necessitates the development of new therapies. Drug development over the past 10 years has generally been disappointing, but several new promising compounds have been or are being developed to prevent acute and chronic transplant rejection. In this Review, we report on several compounds that have been developed to remove allogenic T cells and/or to inhibit T-cell activation. We also discuss compounds that interfere with antibody-mediated rejection. Durrbach, A. et al. Nat. Rev. Nephrol. 6, 160–167 (2010); published online 2 February 2010; doi:10.1038/nrneph.2009.233 Introduction Renal transplantation has specific features that make or as a result of previous transplantation, has increased it different from transplantation procedures for other over the past decade. In addition, ABO­incompatible organs. For example, outcomes can be affected by grafts are becoming more frequently used. Together, these common states, such as donor and/or recipient age, high factors have led to a rise in the number of ‘immuno logically blood pressure, diabetes mellitus, metabolic disturbances at­risk’ kidney transplantations. Few immunosuppressants (such as high LDL cholesterol) and abnormalities in fluid targeted to B cells have, however, been available to control and electrolyte balance.

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.

The negative impact of MA use on individuals and communities warrants its consideration as a public health concern. MA has a complicated pharmacological action, and chronic use results in neurological dysfunction, including deficits in dopamine. Changes in dopaminergic function make treatment of MA dependence especially challenging, and the mainstay treatment of psychotherapy is insufficient in addressing dopamine deficit. Pharmacological treatments are being explored, but no medication has attained Federal Drug Administration approval, as it requires proof of achieving abstinence.

However, unwanted adverse reactions — including serious infections, malignancy, cytokine release syndrome, anaphylaxis and hypersensitivity as well as immunogenicity — pose a challenge to the development of new (and safer) immunomodulatory biologics. In this article, we assess the safety issues associated with immunomodulatory biologics and discuss the current approaches for predicting and mitigating adverse reactions associated with their use. We also outline how these approaches can inform the development of safer immunomodulatory biologics.
