Why and How to Perform Therapeutic Drug Monitoring for Mycophenolate Mofetil
Trends in Transplantation 2007;12007;1:24-34 Why and How to Perform Therapeutic Drug Monitoring for Mycophenolate Mofetil Brenda de Winter and Teun van Gelder Department of Hospital Pharmacy, Clinical Pharmacology Unit, Erasmus Medical Centre, Rotterdam, the Netherlands Abstract The introduction of the immunosuppressive agent mycophenolate mofetil as a standard-dose drug has resulted in a reduced risk of rejection after renal transplantation and improved graft survival compared to azathioprine. The favorable balance between efficacy and safety has made mycophenolate mofetil a cornerstone immunosuppressive drug, and the vast majority of newly transplanted patients are now started on mycophenolate mofetil therapy. Despite the obvious success of mycophenolate mofetil as a standard-dose drug, there is reason to believe that the “one size fits all” approach is not optimal. Recent studies have shown that the pharmacokinetics of mycophenolic acid are influenced by patient charac- teristics such as gender, time after transplantation, serum albumin concentration, renal function, co-medication, and pharmacogenetic factors. As a result, with standard-dose therapy there is wide between-patient variability in exposure of mycophenolic acid. This variability is of clinical relevance because it has repeatedly been shown that exposure to the active metabolite mycophenolic acid is correlated with the risk of developing acute rejection. Especially with the increasing popularity of immunosuppressive regimens in which the concomitant immunosuppression is reduced or eliminated, ensuring an appropri- ate level of immunosuppression afforded by mycophenolic acid is of utmost importance. By introducing therapeutic drug monitoring, mycophenolic acid exposure can be targeted to the widely accepted therapeutic window (mycophenolic acid AUC0-12 between 30 and 60 mg·h/l). -

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.

Kevin Park1 Abstract | Immunomodulatory biologics, which render their therapeutic effects by modulating or harnessing immune responses, have proven their therapeutic utility in several complex conditions including cancer and autoimmune diseases. 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. Immunomodulatory Biologics currently represent more than 30% of licensed The high specificity of the interactions of immu- biologics pharmaceutical products and have expanded the thera- nomodulatory biologics with their relevant immune Biotechnology-derived peutic options available -

Comparative Effectiveness of Immunosuppressive Drugs and Corticosteroids for Lupus Nephritis: a Systematic Review and Network Meta-Analysis Jasvinder A
Singh et al. Systematic Reviews (2016) 5:155 DOI 10.1186/s13643-016-0328-z RESEARCH Open Access Comparative effectiveness of immunosuppressive drugs and corticosteroids for lupus nephritis: a systematic review and network meta-analysis Jasvinder A. Singh1,2,3*, Alomgir Hossain4, Ahmed Kotb4 and George A. Wells4 Abstract Background: There is a lack of high-quality meta-analyses and network meta-analyses of immunosuppressive drugs for lupus nephritis. Our objective was to assess the comparative benefits and harms of immunosuppressive drugs and corticosteroids in lupus nephritis. Methods: We conducted a systematic review and network meta-analysis (NMA) of trials of immunosuppressive drugs and corticosteroids in patients with lupus nephritis. We calculated odds ratios (OR) and 95 % credible intervals (CrI). Results: Sixty-five studies that met inclusion and exclusion criteria; data were analyzed for renal remission/response (37 trials; 2697 patients), renal relapse/flare (13 studies; 1108 patients), amenorrhea/ovarian failure (eight trials; 839 patients) and cytopenia (16 trials; 2257 patients). Cyclophosphamide [CYC] low dose (LD) and CYC high-dose (HD) were less likely than mycophenolate mofetil [MMF] and azathioprine [AZA], CYC LD, CYC HD and plasmapharesis less likely than cyclosporine [CSA] to achieve renal remission/response. Tacrolimus [TAC] was more likely than CYC LD to achieve renal remission/response. MMF and CYC were associated with a lower odds of renal relapse/flare compared to PRED and MMF was associated with a lower rate of renal relapse/flare than AZA. CYC was more likely than MMF and PRED to be associated with amenorrhea/ovarian failure. Compared to MMF, CYC, AZA, CYC LD, and CYC HD were associated with a higher risk of cytopenia. -

EISAI SUBMITS MARKETING AUTHORIZATION APPLICATION IN JAPAN FOR ANTICANCER AGENT DENILEUKIN DIFTITOX (GENETIC RECOMBINANT) FOR CUTANEOUS T-CELL LYMPHOMA AND PERIPHERAL T-CELL LYMPHOMA Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that it has submitted in Japan a marketing authorization application of the anticancer agent denileukin diftitox (genetic recombinant) (generic name, development code: E7777) for relapsed or refractory Cutaneous T-cell Lymphoma (CTCL) and Peripheral T-cell Lymphoma (PTCL). This application is based on data from a multicenter, open-label, single-arm Phase II clinical study (study 205) conducted in Japan for patients with relapsed or refractory CTCL or PTCL to evaluate the efficacy and safety of this agent. This study achieved the primary endpoint and exceeded a predetermined threshold with statistical significance: the objective response rate (ORR) of CTCL and PTCL patients in total (n=36) was 36.1% (95% confidence interval (CI): 20.8-53.8). The ORRs of each subtype were 31.6% (95% CI:12.6-56.6) for CTCL (n=19) and 41.2% (95%CI: 18.4-67.1) for PTCL (n=17). The five most frequent adverse events observed in this study were increased aspartate aminotransferase (AST) (89.2%), increased alanine aminotransferase (ALT) (86.5%), hypoalbuminaemia (70.3%), lymphopenia (70.3%), and pyrexia (51.4%). Denileukin diftitox (genetic recombinant) is a fusion protein of the receptor-binding portion of interleukin-2 (IL-2) and diphtheria toxin that specifically binds to the IL-2 receptor on the surface of tumoral lymphocyte.
