Effects of Febuxostat on Autistic Behaviors and Computational Investigations of Diffusion and Pharmacokinetics
Effects of Febuxostat on Autistic Behaviors and Computational Investigations of Diffusion and Pharmacokinetics Jamelle M. Simmons Dissertation submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biomedical Engineering Yong W. Lee, Chair Luke E. Achenie Hampton C. Gabler Alexei Morozov Aaron S. Goldstein John H. Rossmeisl November 27, 2018 Blacksburg, Virginia Keywords: Autism Spectrum Disorder, Xanthine Oxidase, Reactive Oxygen Species, Pharmacokinetics, Animal Behavior Copyright 2019, Jamelle M. Simmons Effects of Febuxostat on Autistic Behaviors and Computational Investigations of Diffusion and Pharmacokinetics Jamelle M. Simmons (ABSTRACT) Autism spectrum disorder (ASD) is a lifelong disability that has seen a rise in prevalence from 1 in 150 children to 1 in 59 between 2000 and 2014. Patients show behavioral ab- normalities in the areas of social interaction, communication, and restrictive and repetitive behaviors. As of now, the exact cause of ASD is unknown and literature points to multiple causes. The work contained within this dissertation explored the reduction of oxidative stress in brain tissue induced by xanthine oxidase (XO). Febuxostat is a new FDA approved XO- inhibitor that has been shown to be more selective and potent than allopurinol in patients with gout.The first study developed a computational model to calculate an effective diffu- sion constant (Deff ) of lipophilic compounds, such as febuxostat, that can cross endothelial cells of the blood-brain barrier (BBB) by the transcellular pathway. In the second study, male juvenile autistic (BTBR) mice were treated with febuxostat for seven days followed by behavioral testing and quantification of oxidative stress in brain tissue compared to controls.

Guideline for Preoperative Medication Management
Guideline: Preoperative Medication Management Guideline for Preoperative Medication Management Purpose of Guideline: To provide guidance to physicians, advanced practice providers (APPs), pharmacists, and nurses regarding medication management in the preoperative setting. Background: Appropriate perioperative medication management is essential to ensure positive surgical outcomes and prevent medication misadventures.1 Results from a prospective analysis of 1,025 patients admitted to a general surgical unit concluded that patients on at least one medication for a chronic disease are 2.7 times more likely to experience surgical complications compared with those not taking any medications. As the aging population requires more medication use and the availability of various nonprescription medications continues to increase, so does the risk of polypharmacy and the need for perioperative medication guidance.2 There are no well-designed trials to support evidence-based recommendations for perioperative medication management; however, general principles and best practice approaches are available. General considerations for perioperative medication management include a thorough medication history, understanding of the medication pharmacokinetics and potential for withdrawal symptoms, understanding the risks associated with the surgical procedure and the risks of medication discontinuation based on the intended indication. Clinical judgement must be exercised, especially if medication pharmacokinetics are not predictable or there are significant risks associated with inappropriate medication withdrawal (eg, tolerance) or continuation (eg, postsurgical infection).2 Clinical Assessment: Prior to instructing the patient on preoperative medication management, completion of a thorough medication history is recommended – including all information on prescription medications, over-the-counter medications, “as needed” medications, vitamins, supplements, and herbal medications. Allergies should also be verified and documented.

Cross-Over Trial of Febuxostat and Topiroxostat for Hyperuricemia with Cardiovascular Disease (TROFEO Trial)
Circ J 2017; 81: 1707 – 1712 ORIGINAL ARTICLE doi: 10.1253/circj.CJ-17-0438 Preventive Medicine Cross-Over Trial of Febuxostat and Topiroxostat for Hyperuricemia With Cardiovascular Disease (TROFEO Trial) Akira Sezai, MD, PhD; Kazuaki Obata; Keisuke Abe; Sakie Kanno; Hisakuni Sekino, MD, PhD Background: We previously reported that febuxostat was more effective for hyperuricemia than allopurinol. The efficacy, however, of topiroxostat (a novel xanthine oxidase reductase inhibitor similar to febuxostat), for hyperuricemia is unknown. Methods and Results: Patients with cardiovascular disease and hyperuricemia, in whom serum uric acid (s-UA) was controlled at ≤6 mg/dL, were eligible for enrollment. Fifty-five patients were randomized to receive either febuxostat or topiroxostat for 6 months and were switched to the other drug for the following 6 months. The primary endpoint was s-UA. Secondary endpoints included serum creatinine, estimated glomerular filtration rate, urinary albumin, cystatin-C, oxidized low-density lipoprotein, eicosapentaenoic acid/ arachidonic acid ratio, lipid biomarkers, high-sensitivity C-reactive protein and B-type natriuretic protein. Although s-UA level was similar for both drugs, significantly more patients required dose escalation during treatment with topiroxostat. There were no differ- ences in renal function, inflammatory and lipid markers between the 2 drugs. A biomarker of oxidative stress was significantly lower after 3 months of febuxostat compared with topiroxostat. Conclusions: Febuxostat causes more marked and more rapid reduction of s-UA than topiroxostat. With regard to the antioxidant effect, febuxostat was superior to topiroxostat after 3 months. The renal protective and anti-inflammatory effects of both drugs were also similar after 6 months of treatment.

Febuxostat Pretreatment Attenuates Myocardial Ischemia/Reperfusion
Wang et al. J Transl Med (2015) 13:209 DOI 10.1186/s12967-015-0578-x RESEARCH Open Access Febuxostat pretreatment attenuates myocardial ischemia/reperfusion injury via mitochondrial apoptosis Shulin Wang, Yunpeng Li, Xudong Song, Xianbao Wang, Cong Zhao, Aihua Chen* and Pingzhen Yang* Abstract Background: Febuxostat is a selective inhibitor of xanthine oxidase (XO). XO is a critical source of reactive oxygen species (ROS) during myocardial ischemia/reperfusion (I/R) injury. Inhibition of XO is therapeutically effective in I/R injury. Evidence suggests that febuxostat exerts antioxidant effects by directly scavenging ROS. The present study was performed to investigate the effects of febuxostat on myocardial I/R injury and its underlying mechanisms. Methods: We utilized an in vivo mouse model of myocardial I/R injury and an in vitro neonatal rat cardiomyocyte (NRC) model of hypoxia/reoxygenation (H/R) injury. Mice were randomized into five groups: Sham, I/R (I/R Vehicle), I/R FEB (I/R febuxostat), AL I/R (I/R allopurinol) and FEB (febuxostat), respectively. The I/R FEB mice+ were pretreated+ with+ febuxostat (5 mg/kg;+ i.p.) +24 and 1 h prior to I/R. NRCs received febuxostat (1 and 10+ µM) at 24 and 1 h before exposure to hypoxia for 3 h followed by reoxygenation for 3 h. Cardiac function, myocardial infarct size, serum levels of creatine kinase (CK) and lactate dehydrogenase (LDH), and myocardial apoptotic index (AI) were measured in order to ascertain the effects of febuxostat on myocardial I/R injury. Hypoxia/reperfusion (H/R) injury in NRCs was examined using MTT, LDH leakage assay and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay.

Summary of Risk Management Plan for Adenuric (Febuxostat)
SUMMARY OF RISK MANAGEMENT PLAN FOR ADENURIC (FEBUXOSTAT) This is a summary of the risk management plan (RMP) for Adenuric. The RMP details important risks of Adenuric, how these risks can be minimised, and how more information will be obtained about Adenuric's risks and uncertainties (missing information). Adenuric's summary of product characteristics (SmPC) and its package leaflet give essential information to healthcare professionals and patients on how Adenuric should be used. This summary of the RMP for Adenuric should be read in the context of all this information including the assessment report of the evaluation and its plain-language summary, all which is part of the European Public Assessment Report (EPAR). Important new concerns or changes to the current ones will be included in updates of Adenuric 's RMP. I. THE MEDICINE AND WHAT IT IS USED FOR Adenuric is authorised for the treatment of chronic hyperuricaemia in conditions where urate deposition has already occurred (including a history, or presence of, tophus and/or gouty arthritis) and for the prevention and treatment of hyperuricaemia in adult patients undergoing chemotherapy for haematologic malignancies at intermediate to high risk of Tumor Lysis Syndrome (TLS) (see SmPC for the full indication). It contains febuxostat as the active substance and it is given by oral formulations (80 mg film-coated tablets and 120 mg film- coated tablets). Further information about the evaluation of Adenuric’s benefits can be found in Adenuric ’s EPAR, including in its plain-language summary, available on the EMA website, under the medicine’s webpage. II. RISKS ASSOCIATED WITH THE MEDICINE AND ACTIVITIES TO MINIMISE OR FURTHER CHARACTERISE THE RISKS Important risks of Adenuric, together with measures to minimise such risks and the proposed studies for learning more about Adenuric's risks, are outlined below.
