Abstract
BI-X, a therapeutic protein under development for the treatment of human ocular disease via intravitreal administration, binds to its therapeutic targets and endogenous albumin in the vitreous humor. A monkey ocular pharmacokinetic (PK) study following BI-X administration was conducted to measure drug and albumin levels in plasma, the vitreous humor, the aqueous humor, and retina tissue at various timepoints post-dose. A comprehensive bioanalytical approach was implemented in support of this study. Five immunocapture-LC-MS/MS assays were developed and qualified for quantitating BI-X in different matrices, while ELISA was used for albumin measurement. Immunocapture at the protein or peptide level was evaluated to achieve adequate assay sensitivity. Drug and albumin assays were applied for the analysis of the monkey study samples.

Abstract
Noninfectious uveitis is a common blinding eye disease, and an autoimmune response is involved in its pathogenesis. Biological agents have gradually been introduced into the treatment of noninfectious uveitis. The authors reviewed the clinical application and side effects of different biological agents on noninfectious uveitis. Biological agents that target TNF-α are widely used in the clinic. Other biological agents, such as IL-6- and IL-1-neutralizing antibodies, are used in patients who do not respond to TNF inhibitors. The efficacy of IL-17 neutralizing antibodies in noninfectious uveitis is controversial. Biological agents targeting T cells and signaling pathways provide new drug options for treatment of noninfectious uveitis. However, it cannot be ignored that these biological agents have side effects, such as increasing risk of infection.

Abstract
Purpose: Many diseases of the cornea and ocular surface are manifestations of an underlying autoimmune process and require systemic immunosuppression for their management. These cases often present to a general ophthalmologist before being referred to an ocular immunologist or rheumatologist. However, the patients do need to be followed by the ophthalmologist to assess disease progression or for management of ocular co-morbidities and for taking care of ocular complications of the disease. Undeniably, there is a certain hesitance to promptly initiate them on systemic therapy because the literature regarding the indications, dosages, and side effects of this group of drugs is vast and dispersed.The aim of this review is to provide a source of ready reference for the general ophthalmologist as well as trainees and residents, on systemic immunosuppression for corneal and ocular surface disease. Methods: This review included 153 studies which were published as randomized controlled trials, systematic reviews, or as nonrandomized comparative studies (cohort or case-control series) on the topic of systemic immunosuppression in cornea and ocular surface disorders.Results: This review provides a concise summary of both the types of drugs and the common indications where they would be indicated, along with treatment and monitoring algorithms for each specific disease condition. The most used group of drugs are corticosteroids, which have significant side effects, particularly when administered systemically or for longer periods of time. To overcome this, steroid-sparing immunosuppressants are recommended. The four main classes of immunosuppressants used today are antimetabolites, T-cell inhibitors, alkylating agents and biologic agents. This review details the use of these drugs in ocular surface inflammation, including the dosing schedule, side effects and monitoring in allergic conjunctivitis, mucous membrane pemphigoid, peripheral ulcerative keratitis, immunological rejection against corneal allografts, anterior scleritis and aqueous deficiency dry eyes. Conclusions: This review provides an uncluttered and wholesome understanding of systemic immunosuppression in cornea and ocular surface diseases, with the hope that this will serve as a ready reckoner and help bridge the gap between ophthalmology and rheumatology for the betterment of our patients.

Abstract
INTRODUCTION Axial spondyloarthritis (axSpA) is an inflammatory arthritis which affects primarily the entheses of the spine and sacroiliac joints with peripheral joint synovitis and extra-articular manifestations. In 2017, the first IL-17A inhibitor (IL-17Ai) secukinumab was approved for the treatment of radiographic axSpA not responding adequately to conventional therapies, and this was followed in 2019 by a second IL-17Ai, ixekizumab. These agents represent the first alternative class of biological treatments after the TNF inhibitor which dominated the therapeutic landscape of axSpA for over a decade. AREAS COVERED This review discusses the role of IL-17Ais in the treatment in axSpA focusing on the newest IL-17Ai ixekizumab. It provides a detailed overview of the drug pharmacodynamic, pharmacokinetics, and clinical trial data, including areas of future research needed in the post-marketing era. EXPERT OPINION Early trials of ixekizumab for axSpA have shown encouraging results and an acceptable safety profile. Future phase IV trials should focus on direct head-to-head comparisons between ixekizumab and other biologic drugs, and stratify patients according to important disease characteristics known to affect treatment response including sex, HLA-B27 status, presence of MRI bone marrow edema at baseline, disease duration and any extra-articular manifestations.

Abstract
The profound impact that vision loss has on human activities and quality of life necessitates understanding the etiology of potentially blinding diseases and their clinical management. The unique anatomic features of the eye and its sequestration from peripheral immune system also provides a framework for studying other diseases in immune privileged sites and validating basic immunological principles. Thus, early studies of intraocular inflammatory diseases (uveitis) were at the forefront of research on organ transplantation. These studies laid the groundwork for foundational discoveries on how immune system distinguishes self from non-self and established current concepts of acquired immune tolerance and autoimmunity. Our charge in this review is to examine how advances in molecular cell biology and immunology over the past 3 decades have contributed to the understanding of mechanisms that underlie immunopathogenesis of uveitis. Particular emphasis is on how advances in biotechnology have been leveraged in developing biologics and cell-based immunotherapies for uveitis and other neuroinflammatory diseases.

Abstract
BACKGROUND Uveitis is an inflammatory and heterogeneous ocular disorder and has a profound impact on patients' life, work and family. There are substantial costs to the countries and individuals associated with treatment of the complications of uveitis and blindness. Conventional therapies did not lead to satisfactory outcomes for uveitis and are associated with substantial adverse events (AEs). Emerging evidences have proved the important value and potential prospect of Chinese medicines and its compound in uveitis. However, although Chinese medicines are widely used in uveitis, its therapeutic effect and safety are still controversial. It is, therefore, timely to perform an objective and normative systematic review to assess the efficacy and safety of Chinese medicines in treating uveitis on current research. METHODS The systematic review will include all of the randomized controlled trials (RCT) on the efficacy and safety of Chinese medicines for uveitis. A relevant literature search by sensitive search strategies was conducted using the following electronic databases from their inception to September 30, 2019: PubMed, Web of Science, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal database (VIP) and Chinese Biomedical Literature database (CBM). The strategy combines treatment terms and disease: that is, "Medicine, Chinese Traditional" (e.g., "Medicine, Chinese Traditional", TCM, Traditional Chinese medicine, Zhong Yi Xue) and uveitis. We will also search registers of clinical trials, potential gray literature, and conference abstracts. There are no limits on language and publication status. The literature screening, data extraction, and quality assessment will be conducted by 2 reviewers independently. The reporting quality and risk of bias will be assessed by other two researchers. Best-corrected visual acuity (BCVA) and improvement in disease activity were assessed as the primary outcome. The secondary outcomes will include laboratory efficacy indexes, score changes in the National Eye Institute Visual Functioning Questionnaire 25 (NEI-VFQ 25), uveitis-related tissue damage or complications, concurrent requirement of corticosteroids, immunosuppressive drugs or biologics, and AEs of treatment. Meta-analysis will be performed using RevMan5.3 software provided by the Cochrane Collaboration. RESULTS This study will provide a comprehensive review based on current evidence of Chinese medicines treatment for uveitis in several aspects, including BCVA and improvement in disease activity, laboratory efficacy indexes, score changes in the NEI-VFQ 25, uveitis-related tissue damage or complications, etc. CONCLUSION:: The conclusion of this study will provide evidence to determine whether Chinese medicines are an effective and safe intervention for patients with uveitis. ETHICS AND DISSEMINATION It is not necessary to obtain ethical approval for this study, given that this protocol is for a systematic review. The systematic review will be published in a peer-reviewed journal, presented at conferences and will be shared on social media platforms. PROSPERO REGISTRATION NUMBER PROSPERO CRD42020153620.

The associations between interleukin 10 polymorphisms and susceptibility to autoimmune uveitis - a meta-analysis. Cent Eur J Immunol 2019; 44:246-252.

Abstract
Autoimmune uveitis is an ocular inflammatory disease that is associated with genetic factors. Interleukin 10 (IL-10) is an immune-regulatory cytokine of autoimmune diseases. IL-10 is considered a candidate gene for uveitis. We evaluate the association of IL-10 with susceptibility to autoimmune uveitis. The results from seven studies were pooled in the meta-analysis, covering a total of 2893 cases of uveitis and 4873 controls. Published literature from MEDLINE and Embase was retrieved. Meta-analyses were conducted on the associations between autoimmune uveitis and the -1082 A/G and -819 C/T polymorphisms of the IL-10 gene. The meta-analysis revealed no association between uveitis and the IL-10 -1082 A allele (OR = 0.91, 95% CI = 0.64-1.30, p = 0.62). The recessive, dominant, and homozygous models of the IL-10 -1082 A/G allele also suggested no association between autoimmune uveitis and each genotype. The meta-analysis revealed significant association between uveitis and the -892 C allele (OR = 0.81, 95% CI = 0.67-0.98, p = 0.03). In addition, significant association was found in homozygous models (OR = 0.58, 95% CI = 0.36-0.92, p = 0.02). However, the dominant and recessive models of the IL-10 -819 C/T polymorphisms showed no association between uveitis and each genotype. This meta-analysis showed that the -1082 A/G polymorphisms of IL-10 were not associated with autoimmune uveitis, but the -819 C/T polymorphisms were significantly associated with uveitis.

Abstract
BACKGROUND Non-infectious uveitis describes a heterogenous group of ocular disorders characterised by intraocular inflammation in the absence of infection. Uveitis is a leading cause of visual loss, most commonly due to uveitic macular oedema (UMO). Treatment is aimed at reducing disease activity by suppression of the intraocular inflammatory response. In the case of macular oedema, the aim is to restore macular architecture as quickly as possible, in order to prevent irreversible photoreceptor damage in this area. Acute exacerbations are typically managed with corticosteroids, which may be administered topically, locally or systemically. Whilst these are often rapidly effective in achieving disease control, long-term use is associated with significant local and systemic side effects, and 'steroid sparing agents' are typically used to achieve prolonged control in severe or recalcitrant disease. Anti-tumour necrosis factor (TNF) drugs block a critical cytokine in the inflammatory signalling process, and have emerged as effective steroid-sparing immunomodulatory agents in a wide range of non-ocular conditions. There is mechanistic data to suggest that they may provide a more targeted approach to disease control in UMO than other agents, but to date, these agents have predominantly been used 'off label' as the majority are not licensed for ocular use. This review aims to summarise the available literature reporting the use of anti-TNF therapy in UMO, thus developing the evidence-base on which to make future treatment decisions and develop clinical guidelines in this area. OBJECTIVES To assess the efficacy of anti-TNF therapy in treatment of UMO. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 2), which contains the Cochrane Eyes and Vision Trials Register; Ovid MEDLINE; Ovid Embase; LILACS; Web of Science Conference Proceedings Citation Index- Science (CPCI-S); System for Information on Grey Literature in Europe (OpenGrey); the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. The date of the search was 29 March 2018. SELECTION CRITERIA We planned to include all relevant randomised controlled trials assessing the use of anti-TNF agents in treatment of UMO. No limits were applied to participant age, gender or ethnicity. The primary comparisons of this review were: anti-TNF versus no treatment or placebo; anti-TNF versus another pharmacological agent; comparison of different anti-TNF drugs; comparison of different doses and routes of administration of the same anti-TNF drug. The primary outcome measure that we assessed for this review was best-corrected visual acuity (BCVA) in the treated eye. Secondary outcome measures were anatomical macular change, clinical estimation of vitreous haze and health-related quality of life. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts retrieved through the database searches. We retrieved full-text reports of studies categorised as 'unsure' or 'include' after we had reviewed the abstracts. Two review authors independently reviewed each full-text report for eligibility. We resolved discrepancies through discussion. MAIN RESULTS We identified no completed or ongoing trial that was eligible for this Cochrane Review. AUTHORS' CONCLUSIONS Our review did not identify any evidence from randomised controlled trials for or against the role of anti-TNF agents in the management of UMO. Although there are a number of high-quality randomised controlled trials that demonstrate the efficacy of anti-TNF agents in preventing recurrence of inflammation in uveitis, the reported study outcomes do not include changes in UMO. As a result, there were insufficient data to conclude whether there was a significant treatment effect specifically for UMO. Future trials should be designed to include quantitative measures of UMO as primary study outcomes, for example by reporting the presence or absence of UMO, or by measuring central macular thickness for study participants. Furthermore, whilst UMO is an important complication of uveitis, we acknowledge that uveitis is associated with many significant structural and functional complications. It is not possible to determine treatment efficacy based on a single outcome measure. We recommend that future reviews of therapeutic interventions in uveitis should use composite measures of treatment response comprising a range of potential complications of disease.

Abstract
BACKGROUND To assess the efficacy and safety of immunomodulatory drugs in patients with noninfectious anterior uveitis (AU). METHODS Systematic review of studies were retrieved from Medline (1961 to March 2016), Embase (1961 to March 2016), and Cochrane Library (up to March 2016), and a complementary hand search was also performed. The selection criteria were as follows: (population) noninfectious AU patients, adults; (intervention) immunomodulatory drugs (any dose, regimen, route of administration, duration of treatment); (outcome) control of inflammation, steroid-sparing effect, AU flares, adverse events, and so on; (study design) systematic literature reviews, randomized controlled trials, and observational studies. The study quality was assessed using the Jadad scale and according to The Oxford Centre for Evidence-based Medicine (update 2009). RESULTS We included 13 studies of moderate-poor quality, with a mean duration from 5 months to 20 years, and number of AU patients ranging from 9 to 274. Patient's demographic and clinical characteristics were very heterogeneous. In most cases, uveitis anatomic classification criteria and outcomes definitions were unclear. Some of the studies only included AU patients with a systemic disease associated, mostly spondyloarthritis, others, mixed populations (idiopathic and systemic disease associated patients), and in some articles this data is not described. We found that methotrexate, cyclosporine A, azathioprine, adalimumab, and golimumab might prevent AU flares, improve ocular inflammation and visual acuity, and decrease systemic steroids doses. CONCLUSIONS Although there is a lack of robust evidence, methotrexate, cyclosporine A, azathioprine, adalimumab, and golimumab might be effective in AU patients.

Abstract
INTRODUCTION Biologics are generally macromolecules, large in size with poor stability in biological environments. Delivery of biologics to tissues at the back of the eye remains a challenge. To overcome these challenges and treat posterior ocular diseases, several novel approaches have been developed. Nanotechnology-based delivery systems, like drug encapsulation technology, macromolecule implants and gene delivery are under investigation. We provide an overview of emerging technologies for biologics delivery to back of the eye tissues. Moreover, new biologic drugs currently in clinical trials for ocular neovascular diseases have been discussed. Areas covered: Anatomy of the eye, posterior segment disease and diagnosis, barriers to biologic delivery, ocular pharmacokinetic, novel biologic delivery system Expert opinion: Anti-VEGF therapy represents a significant advance in developing biologics for the treatment of ocular neovascular diseases. Various strategies for biologic delivery to posterior ocular tissues are under development with some in early or late stages of clinical trials. Despite significant progress in the delivery of biologics, there is unmet need to develop sustained delivery of biologics with nearly zero-order release kinetics to the back of the eye tissues. In addition, elevated intraocular pressure associated with frequent intravitreal injections of macromolecules is another concern that needs to be addressed.

MC5r and A2Ar Deficiencies During Experimental Autoimmune Uveitis Identifies Distinct T cell Polarization Programs and a Biphasic Regulatory Response. Sci Rep 2016; 6:37790. [PMID: 27886238 PMCID: PMC5122918 DOI: 10.1038/srep37790] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Accepted: 11/02/2016] [Indexed: 12/16/2022] Open
Abstract
Autoantigen-specific regulatory immunity emerges in the spleen of mice recovering from experimental autoimmune uveitis (EAU), a murine model for human autoimmune uveoretinitis. This regulatory immunity provides induced tolerance to ocular autoantigen, and requires melanocortin 5 receptor (MC5r) expression on antigen presenting cells with adenosine 2 A receptor (A2Ar) expression on T cells. During EAU it is not well understood what roles MC5r and A2Ar have on promoting regulatory immunity. Cytokine profile analysis during EAU revealed MC5r and A2Ar each mediate distinct T cell responses, and are responsible for a functional regulatory immune response in the spleen. A2Ar stimulation at EAU onset did not augment this regulatory response, nor bypass the MC5r requirement to induce regulatory immunity. The importance of this pathway in human autoimmune uveitis was assayed. PBMC from uveitis patients were assayed for MC5r expression on monocytes and A2Ar on T cells, and comparison between uveitis patients and healthy controls had no significant difference. The importance for MC5r and A2Ar expression in EAU to promote the induction of protective regulatory immunity, and the expression of MC5r and A2Ar on human immune cells, suggests that it may be possible to utilize the melanocortin-adenosinergic pathways to induce protective immunity in uveitic patients.

The role of Fc-receptors in the uptake and transport of therapeutic antibodies in the retinal pigment epithelium. Exp Eye Res 2016; 145:187-205. [PMID: 26773870 DOI: 10.1016/j.exer.2015.12.013] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2015] [Revised: 11/11/2015] [Accepted: 12/31/2015] [Indexed: 10/22/2022]
Abstract
In the ophthalmological clinic, intravitreally applied antibodies or Fc-containing fusion proteins are frequently used, but the biology and pharmacokinetics of these therapeutics in the retina are not well understood. We have previously shown intracellular uptake of Fc-containing molecules in RPE cells. In this study, we investigated the involvement of Fc-receptors, both Fcγ-receptors and the neonatal Fc-receptor (FcRn) in the uptake and intracellular trafficking of the VEGF-antagonists bevacizumab, aflibercept and the anti-CD20 antibody rituximab in three different model systems, primary porcine RPE cells, ARPE-19 cells and porcine RPE/choroid explants. The expression of Fcγ-receptors was tested in primary porcine RPE cells, and the expression of Fcγ-receptors I and II could be shown in RT-PCR and qRT-PCR, while the expression of FcRn was additionally confirmed in Western blot and immunocytochemistry. All three compounds, bevacizumab, rituximab and aflibercept, were taken up into the cells and displayed a characteristic time-dependent pattern, as shown in Western blot and immunohistochemistry. The uptake was not altered by the inhibition of Fcγ-receptors using different inhibitors (TruStain FcX, genistein, R406). However, the inhibition of FcRn with an antagonistic antibody reduced intracellular IgG in porcine RPE cells (rituximab) and ARPE-19 cells (bevacizumab, rituximab). Colocalisations between the tested compounds and myosin7a could be found. In addition, limited colocalization with FcRn and the tested compounds, as well as triple localization between compound, FcRn and myosin7a could be detected, indicating a role of myosin7a in FcRn mediated transport. However, the colocalizations are restricted to small fractions of the Fc-containing compounds. Furthermore, the FcRn is mainly found in the membrane section, where only minute amounts of the Fc-containing compounds are seen, suggesting a limited interaction. An apical to choroidal transport of IgG through the RPE/choroid can be found in RPE/choroid explants. Inhibition of FcRn increases the amount of bevacizumab found on the choroidal side, suggesting a role of FcRn in the recycling of bevacizumab. In conclusion, our data indicate a role for FcRn, but not Fcγ-receptors, in the uptake and transport of Fc-containing molecules in the RPE and indicate a recycling function of FcRn in the retina.

Abstract
Intraocular inflammatory eye disease is one of the important causes of ocular morbidity. Even though the prevalence of uveitis is less common in relation to diabetic retinopathy, glaucoma or age related macular degeneration, the complexity and heterogeneity of the disease makes it more unique. Putative uveitogenic retinal antigens incite innate immunity by the process of antigen mimicry and have been shown to be associated in patients with intraocular inflammatory disease by numerous experimental studies. Laboratory diagnostic tools to aid the etiologic association in intraocular inflammatory disease have evolved over the last two decades and we are entering into an era of molecular diagnostic tests. Sophisticated novel technologies such as multiplex bead assays to assess biological signatures have revolutionized the management of complex refractory uveitis. Nevertheless, there is still a long way to go to establish the causal relationship between these biomarkers and specific uveitic entities. Experimental studies have shown the supreme role of infliximab in the management of Behcet's disease. Despite significant experimental and case control studies, the deficiency of randomized clinical trials using these biologic agents has handicapped us in exploring them as a front line therapy in severe refractory uveitis. Studies still need to answer the safety of these potentially life threatening drugs in a selected group of patients and determine when to commence and for how long the treatment has to be given. This review article covers some basic concepts of cytokines in uveitis and their potential application for therapy in refractory uveitis.

Abstract
Intraocular inflammation is an important cause of blindness both in the developing and developed world. Corticosteroids play a pivotal role in the treatment of intraocular inflammation. Lately, therapy by immunosuppression has taken the center stage for patients with severe intraocular inflammation. However, the side effects of immunosuppressive drugs are oncogenic, infectious, and hematological. Recently, biologic response modifiers specifically targeting suppression of the immune effector responses have revolutionized the treatment of intraocular inflammation. Anti-tumour necrosis factor agents are etanercept, infliximab, and adalimumab. Newer drugs include certolizumab and golimumab. Infliximab has been found to be superior to corticosteroids in treating retinal vasculitis. Anti-interlenkin therapies include rituximab, daclizumab, anakinra, tocilizumab and secukinumab. Rituximab has been proven to be quite effective. Other biologics used are interferons and abatacept. However, there are several limitations and side effects associated with their use.
