Autoimmun Rev 2024; 23:103530. [PMID: 38499168 DOI: 10.1016/j.autrev.2024.103530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 03/13/2024] [Accepted: 03/13/2024] [Indexed: 03/20/2024]
Abstract
BACKGROUND Formation of anti-drug antibodies (ADAs) against biologics is an important cause of psoriasis treatment failure. OBJECTIVE This study aimed to summarize the characteristics of ADAs formation under different biological therapies and the influence of ADAs on the clinical effects and safety of biologics in patients with psoriasis. METHODS PubMed, Embase, and Web of Science databases were searched from their inception to August 2022. Studies on biologics that assessed ADA levels in patients with psoriasis were included. The Cochrane risk-of-bias tool was used to assess the quality of randomized controlled trials (RCTs), the Newcastle-Ottawa Quality Assessment Scale (NOS) for case-control and cohort studies, and the Joanna Briggs Institute (JBI) critical appraisal checklist for single-arm studies. We calculated the pooled incidence with a random-effects model using R software. Subgroup analyses revealed that differences in patient characteristics, disease conditions, study design, and immunoassays may influence ADA generation and detection. RESULTS The analysis included 86 studies, with a total population of 42,280 individuals. The pooled ADA rates were 0.49%, 2.20%, 2.38%, 4.08%, 7.38%, 7.94%, 14.29%, 21.93%, 29.70%, 31.76%, and 39.58% for secukinumab, etanercept, brodalumab, ustekinumab, tildrakizumab, guselkumab, ixekizumab, risankizumab, infliximab, adalimumab, and bimekizumab, respectively. >70% (95% CI, 0.71-0.81) of ADAs against adalimumab were neutralizing antibodies, and over 70% of ADAs against secukinumab and brodalumab were transient. Concomitant methotrexate therapy with tumor necrosis factor-α (TNF-α) inhibitors decreased ADA levels. Lower infliximab doses and intermittent therapy with interleukin (IL)-23 p19 inhibitors increased ADA formation. Additionally, ADA formation under treatment using TNF-α inhibitors and IL-12/23 p40 inhibitors was associated with lower response rates or serum drug levels, but only high ADA titers reduced the clinical effects of IL-17 inhibitors. The occurrence of IL-23 p19 and TNF-α inhibitors has been linked to injection-site reactions. CONCLUSIONS Among the 11 biologics, secukinumab, etanercept, and brodalumab resulted in the lowest ADA formation rates. Immunogenicity contributes to lower biological efficacy and a higher likelihood of injection-site reactions. Low doses, intermittent treatment may increase ADA formation. An appropriate biologic should be selected based on the ADA formation rate and course of treatment.

Abstract
The COVID-19 vaccination program has probably been the most complex and extensive project in history until now, which has been a challenge for all the people involved in the planning and management of this program. Patients with immune-mediated inflammatory diseases (IMIDs) on immunosuppressive therapy have required special attention, not only because of the particular haste in carrying out the process but also because of the uncertainty regarding their response to the vaccines. We now have strong scientific evidence that supports the hypothesis that immunosuppressive therapy inhibits the humoral response to vaccines against other infectious agents, such as influenza, pneumococcus and hepatitis B. This has led to the hypothesis that the same could happen with the COVID-19 vaccine. Several studies have therefore already been carried out in this area, suggesting that temporarily discontinuing the administration of methotrexate for 2 weeks post-vaccination could improve the vaccine response, and other studies with various immunosuppressive drugs are in the same line. However, the fact of withholding or interrupting immunosuppressive therapy when dealing with COVID-19 vaccination remains unclear. On this basis, our article tries to compile the information available on the effect of immunosuppressant agents on COVID-19 vaccine responses in patients with IMIDs and proposes an algorithm for the management of these patients.

ABCC1, ABCG2 and FOXP3: Predictive Biomarkers of Toxicity from Methotrexate Treatment in Patients Diagnosed with Moderate-to-Severe Psoriasis. Biomedicines 2023; 11:2567. [PMID: 37761008 PMCID: PMC10526923 DOI: 10.3390/biomedicines11092567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/01/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Methotrexate (MTX) is one of the most extensively used drugs in the treatment of moderate-to-severe psoriasis (PS). However, it frequently must be suspended owing to the toxicity in certain patients. OBJECTIVE To evaluate the influence of ABCC1, ABCG2, and FOXP3 in the development of MTX toxicity in PS. METHODS Retrospective cohort study with 101 patients. Five single-nucleotide polymorphisms (SNPs) were genotyped using real-time polymerase chain reaction with TaqMan probes. RESULTS Patients carrying ABCC1 rs2238476-AG genotype (AG vs. GG: OR = 8.04; 95% CI = 1.48-46.78; p = 0.015); FOXP3 rs376154-GT and GG genotypes (GT vs. TT/GG: OR = 3.86; 95% CI = 1.17-13.92; p = 0.031) and ABCG2 rs13120400-T allele (T vs. CC: OR = 8.33; 95% CI = 1.24-164.79; p = 0.059) showed a higher risk of developing more than one adverse effect. The toxicity analysis by subtypes showed that the ABCC1 rs2238476-AG genotype (AG vs. GG: OR = 8.10; 95% CI = 1.69-46.63; p = 0.011) and FOXP3 rs376154-GT genotype (OR = 4.11; 95% CI = 1.22-15.30; p = 0.027) were associated with the appearance of asthenia. No association of the other ABCC1 polymorphisms (rs35592 and rs246240) with MTX toxicity was found. CONCLUSION ABCC1, ABCG2, and FOXP3 polymorphisms can be considered to be risk biomarkers of toxicities in PS patients treated with MTX.

Abstract
Psoriasis is a chronic inflammatory disease with an established genetic background. The HLA-Cw*06 allele and different polymorphisms in genes involved in inflammatory responses and keratinocyte proliferation have been associated with the development of the disease. Despite the effectiveness and safety of psoriasis treatment, a significant percentage of patients still do not achieve adequate disease control. Pharmacogenetic and pharmacogenomic studies on how genetic variations affect drug efficacy and toxicity could provide important clues in this respect. This comprehensive review assessed the available evidence for the role that those different genetic variations may play in the response to psoriasis treatment. One hundred fourteen articles were included in this qualitative synthesis. VDR gene polymorphisms may influence the response to topical vitamin D analogs and phototherapy. Variations affecting the ABC transporter seem to play a role in methotrexate and cyclosporine outcomes. Several single-nucleotide polymorphisms affecting different genes are involved with anti-TNF-α response modulation (TNF-α, TNFRSF1A, TNFRSF1B, TNFAIP3, FCGR2A, FCGR3A, IL-17F, IL-17R, and IL-23R, among others) with conflicting results. HLA-Cw*06 has been the most extensively studied allele, although it has only been robustly related to the response to ustekinumab. However, further research is needed to firmly establish the usefulness of these genetic biomarkers in clinical practice.

Abstract
Biological therapies (BTs) indicated for psoriasis are highly effective; however, not all patients obtain good results, and loss of effectiveness is the main reason for switching. Genetic factors may be involved. The objective of this study was to evaluate the influence of single-nucleotide polymorphisms (SNPs) on the drug survival of tumor necrosis factor inhibitors (anti-TNF) medications and ustekinumab (UTK) in patients diagnosed with moderate-to-severe psoriasis. We conducted an ambispective observational cohort study that included 379 lines of treatment with anti-TNF (n = 247) and UTK (132) in 206 white patients from southern Spain and Italy. The genotyping of the 29 functional SNPs was carried out using real-time polymerase chain reaction (PCR) with TaqMan probes. Drug survival was evaluated with Cox regression and Kaplan-Meier curves. The multivariate analysis showed that the HLA-C rs12191877-T (hazard ratio [HR] = 0.560; 95% CI = 0.40-0.78; p = 0.0006) and TNF-1031 (rs1799964-C) (HR = 0.707; 95% CI = 0.50-0.99; p = 0.048) polymorphisms are associated with anti-TNF drug survival, while TLR5 rs5744174-G (HR = 0.589; 95% CI = 0.37-0.92; p = 0.02), CD84 rs6427528-GG (HR = 0.557; 95% CI = 0.35-0.88; p = 0.013) and PDE3A rs11045392-T together with SLCO1C1 rs3794271-T (HR = 0.508; 95% CI = 0.32-0.79; p = 0.002) are related to UTK survival. The limitations are the sample size and the clustering of anti-TNF drugs; we used a homogeneous cohort of patients from 2 hospitals only. In conclusion, SNPs in the HLA-C, TNF, TLR5, CD84, PDE3A, and SLCO1C1 genes may be useful as biomarkers of drug survival of BTs indicated for psoriasis, making it possible to implement personalized medicine that will reduce financial healthcare costs, facilitate medical decision-making and improve patient quality of life. However, further pharmacogenetic studies need to be conducted to confirm these associations.

Abstract
BACKGROUND As a common skin disease, psoriasis is related to inflammation and immune response. Due to the frequent recurrence of psoriasis, the treatment of psoriasis remains a clinical challenge. As an effective tumor necrosis factor-alpha (TNF-α) inhibitor, etanercept has been used for the treatment of psoriasis. However, some patients with psoriasis have no response to etanercept or discontinue treatment. To improve the therapeutic effect of etanercept, searching the potential biomarkers and investigating the related mechanisms of etanercept in the treatment of psoriasis are vital. MATERIALS AND METHODS We stimulated HaCaT cells with lipopolysaccharide (LPS) to generate cellular psoriatic changes and established an imiquimod (IMQ)-induced psoriasis-like mouse model, and then used an etanercept to treat cell and mouse model. RESULTS Etanercept alleviated IMQ-induced pathological changes and inflammation, and it also decreased the protein expression of high mobility group box 1 (HMGB1), receptor for advanced glycation end-products, and toll-like receptor 4. Moreover, the results of in vitro experiments showed that etanercept inhibited proliferation and inflammation, and promoted cell cycle arrest and apoptosis in LPS-treated HaCaT cells. Knockdown of HMGB1 further enhanced the inhibitory effects of etanercept on LPS-treated HaCaT cell viability and inflammation, while overexpression of HMGB1 notably reversed the inhibitory effects of etanercept on LPS-induced HaCaT cell viability and inflammation. CONCLUSION Etanercept inhibited proliferation and inflammation and promoted cell cycle arrest and apoptosis in LPS-induced HaCaT cells, and etanercept ameliorated inflammation in a psoriasis-like mouse model.

Abstract
Rheumatoid arthritis (RA) is a systemic immune disease characterized by synovial inflammation. Patients with RA commonly experience significant damage to their hand and foot joints, which can lead to joint deformities and even disability. Traditional treatments have several clinical drawbacks, including unclear pharmacological mechanisms and serious side effects. However, the emergence of antibody drugs offers a promising approach to overcome these limitations by specifically targeting interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and other cytokines that are closely related to the onset of RA. This approach reduces the incidence of adverse effects and contributes to significant therapeutic outcomes. Furthermore, combining these antibody drugs with drug delivery nanosystems (DDSs) can improve their tissue accumulation and bioavailability.Herein, we provide a summary of the pathogenesis of RA, the available antibody drugs and DDSs that improve the efficacy of these drugs. However, several challenges need to be addressed in their clinical applications, including patient compliance, stability, immunogenicity, immunosupression, target and synergistic effects. We propose strategies to overcome these limitations. In summary, we are optimistic about the prospects of treating RA with antibody drugs, given their specific targeting mechanisms and the potential benefits of combining them with DDSs.

Abstract
BACKGROUND Factors other than efficacy and safety could influence the survival of biologics in patients with psoriasis. Little is known about whether different disease groups affect drug survival of biologics or not. OBJECTIVE This study aimed to investigate whether the availability of alternative biologics and disease groups could influence drug survival of biologics approved for psoriasis and psoriasis arthritis (PsA). METHODS A nationwide population-based retrospective cohort study was conducted using the Health Insurance and Review Assessment data in Korea between January 2009 and August 2019. RESULTS The drug survival analysis included 5,634 biologic episodes. Ustekinumab was the most frequently prescribed drug (n=2,488, 44.2%). Multivariable time-dependent Cox regression analysis showed that higher age, female sex, no comorbidity, concomitant cyclosporine or acitretin use, biologic-experienced and use of tumor necrosis factor (TNF)-α inhibitors were predictors of drug discontinuation. PsA was a predictor of drug persistence, particularly for TNF-α inhibitors. Ustekinumab and adalimumab discontinuation significantly increased after introducing secukinumab and ustekinumab, respectively. CONCLUSION The availability of alternative biologics and disease groups affect biologic drug survival in patients with psoriasis and PsA.

Abstract
Biological therapies revolutionized the treatment of many chronic inflammatory skin diseases, first of all psoriasis, thanks to their high efficacy and the reduced number of side effects. However, the use of a single biologic drug does not always provide complete control of the disease or associated comorbidities over time. The first biological drugs used for the treatment of psoriasis, tumor necrosis factor alpha inhibitors, have long been used in combination with traditional topical and systemic therapies to induce a complete remission of the disease that could not be achieved with innovative drug alone. Even with the advent of new biological therapies with more precise molecular targets, the challenge of using combination therapies remained. Psoriatic patients often have major comorbidities, such as arthritis, inflammatory bowel disease, uveitis or have other concomitant conditions such as chronic spontaneous urticaria and atopic dermatitis, which may require different biologic treatments than those indicated in psoriasis. The objective of this article is, through a comprehensive revision of the literature, to analyze in which cases the use of the combination of the latest therapies for psoriasis may be useful.

Abstract
Dermatologic pathologies are the fourth most common cause of non-fatal disease worldwide; however, they produce a psychosocial, economic, and occupational impact equal to or greater than other chronic conditions. The most prevalent are actinic keratosis, followed by basal-cell carcinoma, in a lesser proportion acne vulgaris, psoriasis, and hidradenitis suppurativa, among others, and more rarely dermatitis herpetiformis. To treat actinic keratosis and basal-cell carcinoma, 5-fluorouracil (5-FU) 0.5% is administered topically with good results, although in certain patients it produces severe toxicity. On the other hand, dapsone is a drug commonly used in inflammatory skin conditions such as dermatitis herpetiformis; however, it occasionally causes hemolytic anemia. Additionally, biologic drugs indicated for the treatment of moderate-to-severe psoriasis and hidradenitis suppurativa have proved to be effective and safe; nevertheless, a small percentage of patients do not respond to treatment with biologics in the long term or they are ineffective. This interindividual variability in response may be due to alterations in genes that encode proteins involved in the pathologic environment of the disease or the mechanism of action of the medication. Pharmacogenetics studies the relationship between genetic variations and drug response, which is useful for the early identification of non-responsive patients and those with a higher risk of developing toxicity upon treatment. This review describes the pharmacogenetic recommendations with the strongest evidence at present for the treatments used in dermatology, highlighting those included in clinical practice guides. Currently, we could only find pharmacogenetic clinical guidelines for 5-FU. However, the summary of product characteristics for dapsone contains a pharmacogenetic recommendation from the United States Food and Drug Administration. Finally, there is an enormous amount of information from pharmacogenetic studies in patients with dermatologic pathologies (mainly psoriasis) treated with biologic therapies, but they need to be validated in order to be included in clinical practice guides.

Abstract
Psoriasis is a chronic inflammatory skin pathology of autoimmune origin and unknown etiology. There are various therapies for treating it, including a wide range of biopharmaceuticals indicated in moderate-to-severe psoriasis. Depending on their therapeutic target, they are classified as tumor necrosis factor inhibitors (anti-TNF) or cytokine inhibitors (interleukin-12, 23, and 17 antagonists). Although they have proved effective and safe, in clinical practice, many patients show a short- and long-term suboptimal response and even varying degrees of toxicity. This variability in response may be influenced by genetic factors, such as polymorphisms in the genes involved in the pathological environment, metabolism or mechanism of action of the drug that could affect the effectiveness and toxicity of biological therapies. This review assesses pharmacogenetic studies of the impact of genetic factors on response to biopharmaceuticals and toxicity in patients diagnosed with moderate-to-severe psoriasis. The results suggest that polymorphisms detected in the HLA genes, in genes that encode cytokines (TNF, IL genes, TNFAIP3), transporters (PDE3A-SLCO1C1, SLC12A8), receptors (TNFRSF1B, CD84, FCGR2A and FCGR3A, IL17RA, IL23R, TLR genes, PGLYRP4) and associated proteins (TNFAIP3, LY96, TIRAP, FBXL19), as well as other genes implicated in the pathogenesis of psoriasis (CDKAL1, CARD14, PTTG1, MAP3K1, ZNF816A, GBP6, CTNNA2, HTR2A, CTLA4, TAP1) can be used in the future as predictive markers of treatment response and/or toxicity with biological therapies in patients diagnosed with moderate-to-severe psoriasis, tailoring treatment to the individual patient.

Dermatol Ther 2021; 34:e14926. [PMID: 33655646 DOI: 10.1111/dth.14926] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 02/01/2021] [Accepted: 02/27/2021] [Indexed: 02/05/2023]
Abstract
To investigate if the combination of biologics with methotrexate (MTX) would have better performance than biological monotherapy in clinical efficiency and safety for the treatment of psoriasis and psoriatic arthritis (PsA), a systematic review of randomized controlled trials (RCTs) searched from the Pubmed, Cochrane Library, and Embase was conducted. Psoriasis Area and Severity Index (PASI) responses (including PASI 50, 75, and 90), and proportion of patients with Physician's Global Assessment Scale (sPGA) scored 0 or 1, were used for psoriasis assessment. The American College of Rheumatology (ACR)20/50/70 responder indices were used to assess the efficiency for treating PsA. The incidences of adverse events and antidrug antibodies' development were also recorded. A total of 15 studies with 4221 patients were included in this study. Three of the 15 RCTs were categorized as low risk of bias, nine studies as unclear, and three as high. Significant greater improvement in the combination group than monotherapy group for psoriasis was observed at week 12, week 24, and week 48, with no increased risk of severe adverse events and drug withdrawals due to adverse events. There was no significant difference in the comparison of clinical efficiency for the treatment of PsA at week 24. In conclusion, biologics plus MTX made better performance on improving the clinical efficiency for the treatment of psoriasis when compared with biologic monotherapy, without a difference in tolerability. However, this combination cannot improve the clinical efficiency of PsA treatment and more studies are warranted to elucidate relevant problems.

Abstract
Anti-drug antibodies (ADAs) may develop against originator biologic and biosimilar therapies used for the treatment of psoriasis and may be the cause of initial therapeutic non-response or diminished therapeutic response over time. Comparing immunogenicity between therapeutic agents is challenging owing to the variation in assays used for detection, among other reasons. Using the results of a PubMed search for psoriasis clinical trials disclosing the rates of ADAs for originator biologic and biosimilar therapies approved for the treatment of psoriasis within the last 5 years, this review discusses the rates and potential clinical impact of ADA formation in patients with psoriasis managed with originator biologic and biosimilar therapies, along with novel methods of ADA testing. Anti-drug antibodies are detectable in all biologic and biosimilar therapies approved for the treatment of psoriasis in the last 5 years, and the effect of ADAs on clinical response varies by agent. Novel immunoassays used for the detection of ADAs may have increased sensitivity compared with traditional assays, although the increased rate of detection may not correlate with decreased clinical response and the decision to test for the presence of ADAs may vary from patient to patient. Though ADA formation seems ubiquitous with the use of biologic agents for the treatment of psoriasis, the increased rates of ADAs detected by novel immunoassays may not necessarily correlate with decreased treatment efficacy.

Abstract
Monoclonal antibodies or fusion proteins, defined as biological drugs, have modified the natural history of numerous immune-mediated disorders, allowing the development of therapies aimed at blocking the pathophysiological pathways of the disease, providing greater efficacy and safety than conventional treatment strategies. Virtually all therapeutic proteins elicit an immune response, producing anti-drug antibodies (ADAs) against hypervariable regions of immunoglobulins. Immunogenicity against biological drugs can alter their pharmacokinetic and pharmacodynamic properties, thereby reducing the efficacy of these drugs. In more severe cases, ADAs can neutralize the therapeutic effects of the drug or cause serious adverse effects, mainly hypersensitivity reactions. The prevalence of ADAs varies widely depending on the type of test used, occurrence of false-negative results, and non-specific binding to the drug, making it difficult to accurately assess their clinical impact. Concomitant use of immunosuppressors efficiently reduces the immunogenicity in a dose-dependent manner, either by decreasing the frequency of detectable ADAs or by delaying their appearance, thereby enhancing the effectiveness of biological therapies. Among the new therapeutic strategies for the management of psoriasis, biological agents have gained increasing importance in recent years as they interrupt key inflammation pathways involved in the physiopathology of the disease. Reports regarding ADA in new biologics are still scarce, but the most recent evidence tends to show little impact on the clinical response to the drug, even with prolonged treatment. It is therefore essential to standardize laboratory tests to determine the presence and titles of ADAs to establish their administration and management guidelines that allow the determination of the real clinical impact of these drugs.

Abstract
Introduction: Psoriasis is a chronic inflammatory skin disease that waxes and wanes, and long-term remission can be difficult to achieve regardless of disease severity. Currently, numerous treatment options are available for psoriasis including steroid and non-steroid topical agents, phototherapy, oral systemic agents, and biologics, with many more therapeutic agents under development.Areas covered: This article will review various combination therapy strategies such as rotational therapy and sequential therapy and describe a variety of safe and effective combination therapies for the treatment of psoriasis. Two or more agents with different mechanisms of action and safety profiles can be used to achieve and/or maintain adequate disease control while minimizing the toxicity of treatments. Combination therapy can also be used when a single agent is not enough for treating recalcitrant disease. Choosing a combination regimen that maximizes safety and efficacy while considering patient usability and compliance can be a challenge.Expert opinion: Given the various treatment options currently available for psoriasis and more agents under development, combination therapy will continue to be a valuable treatment strategy for any patient with psoriasis. It is crucial for clinicians to carefully consider the fine balance between safety and efficacy when combining various therapeutic agents.

Abstract
Introduction Antidrug antibody (ADA) production may be the reason behind secondary inefficacy of anti-TNF-α therapy in psoriasis. Aim To investigate the production of ADA, serum tumor necrosis factor α (TNF-α) and drug levels as predictors of clinical response in real-life circumstances. Material and methods Serum drug concentrations (TNFi), the presence of ADAs and serum TNF-α levels were measured in 158 patients by the ELISA method. Clinical response was evaluated by calculating PASI. Their correlation has been statistically analysed. Results In adalimumab and infliximab treated patients, ADA formation was observed in 18.4% and 33%, respectively, and the serum TNFi concentration was significantly higher in the ADA negative groups. In contrast there was no ADA formation detected among etanercept treated patients. The serum TNFi concentration was significantly lower among non-responders (n = 33). The serum TNF-α level was also measured and the correlation with the concentration of the serum TNFi level was analysed. Having evaluated the results of all patients together, the serum TNFi and TNF-α concentrations showed a significant negative correlation. However, when groups were analysed separately, in case of adalimumab, a significant negative correlation was detected between serum TNFi and TNF-α concentrations. With respect to infliximab, there was no significant correlation, and an inverse correlation was found in the etanercept group. The TNF-α levels and ADA positivity were significantly higher in non-responders. Conclusions This study revealed the major role of ADAs against TNFi in case of secondary inefficacy in real-life circumstances. ADA levels show a stronger correlation with PASI failure than serum TNFi or TNF-α levels.

Abstract
The introduction of biologic drugs for the treatment of moderate-to-severe psoriasis resulted in a significant improvement in patients' health. Moreover, treatment regimens in psoriatic patients should be tailored to meet specific needs based on disease severity, impact on quality of life, response to previous therapies and presence of comorbidities. Combination therapy of biologic agents with conventional systemic drugs has been proposed to optimize psoriasis treatment outcomes in unresponsive or partial responsive severe psoriatic patients. We report the case of a patient with a long-standing recalcitrant plaque psoriasis and psoriatic arthritis who was administered secukinumab combined with methotrexate. The patient had previously been treated with several topical and systemic therapies associated with loss of efficacy or adverse event occurrence. Approximately 24 weeks after starting the combined regimen, significant clearance of psoriasis and reduction of arthritis ensued, with no drug side effects.

Abstract
AIMS To evaluate the therapeutic benefits of Hesperidin (Hes) using an imiquimod (IMQ)-induced psoriasis-like mouse model and human immortalized keratinocytes (HaCaT) cells stimulated with lipopolysaccharide (LPS). METHODS Mice were treated with IMQ and orally administered Hes (125-500 mg/kg/day), methotrexate (MTX) 1 mg/kg/day or distilled water. HaCaT cells were stimulated with LPS (1 μg/mL) and relevant indices were measured after administration with different concentrations of Hes (5-20 μg/mL) for 24 h. Inflammatory skin lesions in IMQ mice were evaluated using the psoriasis area severity index (PASI) and pathological staining. Proteins in the IRS-1/ERK1/2 pathway and inflammatory factors were assessed using western blotting or quantitative real-time PCR. In addition, factors related to IRS-1 secretion levels were assessed by enzyme-linked immunosorbent assays. Extracellular flux (XF) analysis was used to assess cellular metabolic levels. KEY FINDINGS Hes significantly improved psoriasis-like skin lesions of IMQ-treated mice and inhibited LPS-induced HaCaT cell proliferation. In addition, Hes remarkably decreased PASI scores, reduced epidermal thickness, decreased proliferation and differentiation of epidermal cells, inhibited mRNA expression of inflammatory factors, reduced local skin lesions and serum insulin and glucose levels. Furthermore, Hes modulated the secretion levels of serum Leptin, Adiponectin and Resistin, and inhibited the activation of the IRS-1/ERK1/2 signaling pathway and regulated HaCaT cells metabolism. SIGNIFICANCE This study demonstrated that Hes administration could have significant therapeutic value for the prevention and clinical treatment of psoriasis.

Abstract
BACKGROUND Loss of efficacy is a major anticipated shortcoming of utilizing etanercept and other biologic agents for treating moderate-to-severe psoriasis. PURPOSE To investigate the addition of low-dose methotrexate as a means to increase etanercept drug survival. METHODS Eleven patients with severe psoriasis were switched to a combination of etanercept with low-dose methotrexate therapy, after a primary or secondary failure with etanercept treatment as a monotherapy. Time period for cessation of combined treatment and side effects were documented. The effect of previous methotrexate treatment was investigated. RESULTS Six men and five women were included in the study. The patients had moderate-to-severe psoriasis with a mean baseline Psoriasis Area and Severity Index (PASI) of 29 (median 25). Median duration of etanercept monotherapy was 12 months. Median duration of combined treatment was 13 months. Combined treatment was discontinued in three patients due to side effects. Previous failure of methotrexate monotherapy did not alter the duration of the combined treatment. CONCLUSION Addition of low-dose methotrexate may rescue etanercept therapy after failure of etanercept monotherapy in patients with moderate-to-severe psoriasis.

Abstract
Introduction Secukinumab, a fully human monoclonal antibody that selectively neutralizes IL-17A, has been shown to have significant efficacy in the treatment of moderate to severe plaque psoriasis (PsO) and psoriatic arthritis (PsA), demonstrating a rapid onset of action and sustained responses with a favorable safety profile. All biotherapeutics, including monoclonal antibodies (mAbs), can be immunogenic, leading to formation of anti-drug antibodies (ADAs) that can result in loss of response and adverse events such as hypersensitivity reactions. Thus, the immunogenicity potential of biotherapeutics is of particular interest for physicians. Of the 2842 patients receiving secukinumab across six phase 3 psoriasis clinical trials, only 0.4% developed treatment-emergent ADAs over 3 years of treatment. Direct comparison of clinical immunogenicity incidence rates is hampered by the nature of clinical immunogenicity assays, differences in study designs, patient populations, and treatment regimens. Methods We evaluated side-by-side in the same healthy donors two recently approved IL-17A selective antibodies, secukinumab and ixekizumab, along with adalimumab and ustekinumab, for their capacity to induce anti-drug related T cell responses in vitro and estimated their potential for developing ADAs in patients. Results We found that healthy donors show both significantly less frequent T cell responses and lower numbers of pre-existing T cells to secukinumab than to ixekizumab and adalimumab. Although there was a tendency for a lower response to ustekinumab, this difference was not significant. Conclusion In summary, this in vitro study confirms the significantly lower immunogenicity potential and provides an explanation for the lower clinical immunogenicity incidence found for secukinumab in comparison to other approved therapeutic antibodies used to treat plaque psoriasis.

Abstract
Atopic dermatitis is a chronic recurrent inflammatory disease caused, inter alia, by violations of the barrier function of the skin and pathological immune response in the form of an imbalance of Th1 and Th2 lymphocytes with increased production of IL-4, IL-5, IL-13, IL-31. Treatment of severe forms of atopic dermatitis is not an easy task due to the variability of the individual response to treatment, the short duration of the therapeutic effect and the frequent development of undesirable phenomena associated with the use of existing methods of systemic immunosuppressive therapy. The study of the pathogenesis of atopic dermatitis made it possible to identify the spectrum of molecular targets, providing the basis for researching alternative variants to the previously used systemic therapy methods – genetic engineering biological preparations. Contemporary data on the pathogenesis of atopic dermatitis as well as potential molecular targets for innovative biological preparations, the efficacy of which has been evaluated through clinical trials, are presented in the review.

Abstract
The introduction of biologic therapy has revolutionized the treatment of inflammatory bowel disease (IBD). However, like all therapeutic proteins, monoclonal antibodies have immunogenic potential which is influenced by multiple drug- and patient-related factors. The reported incidence of anti-drug antibodies (ADAs) towards biologic drugs in IBD varies greatly in the literature and depends not only on differences in sensitization but also on the assay methodology and the timepoint of measurement. Sensitization with formation of ADAs is associated with an increased risk of infusion reactions, accelerated drug clearance, and a loss of response (LOR) to drug. Recently, a greater understanding of the pharmacokinetics of therapeutic antibodies has led to the development of new strategies to reduce immunogenicity and more efficient use of these drugs. These preventive strategies include regular scheduled dosing with maintenance of stable therapeutic trough drug concentrations, and co-administration of an immunosuppressive. Sub-therapeutic drug concentrations with low levels of ADAs can generally be overcome with dose escalation, whereas the presence of high concentrations of ADAs requires a switch to another therapeutic agent.

Abstract
PURPOSE This study was conducted to examine the relationship between loss of clinical response to anti-tumor necrosis factor (TNF) therapy and the production of anti-drug antibodies (ADAs) and the potential effects of biologic immunogenicity. MATERIALS AND METHODS This observational, non-interventional, cross-sectional study included patients with moderate-to-severe plaque psoriasis and secondary failure of adalimumab, etanercept and infliximab who were seen in the clinical practice setting. Clinical data and blood samples were collected after patient enrollment at the time that next doses of anti-TNF therapy were scheduled. ADA and serum drug concentrations were detected at a central reference laboratory using ELISA. RESULTS Among 137 enrolled patients, ADA were identified in 31/65 (48%), 0/47 and 8/19 (42%) of patients treated with adalimumab, etanercept and infliximab, respectively. The presence of ADA was associated with a slightly worse clinical response in adalimumab-treated patients (Physician Global Assessment score: 3.7 vs. 3.2, ADA-positive vs. ADA-negative patients [p < .05]; correlation between serum ADA titer and body surface area: r = .292 [p = .019]). Concomitant DMARDs were not associated with anti-TNF immunogenicity in any treatment group. CONCLUSIONS Additional evidence is needed from studies of anti-TNF therapy in psoriasis for clinicians to gain a better understanding of the impact of immunogenicity on clinical response.

Abstract
A number of biologics is being used for the treatment of psoriasis. Itolizumab is one such agent which has been approved in India. It is an anti-CD6 monoclonal antibody that acts by binding to scavenger receptor cysteine-rich (SRCR) distal domain 1 of CD6. Itolizumab has been found to be safe, with infusion reactions as the most common adverse effect. However, its advantages and disadvantages over other biologicals and immunosuppressants need to be established. Also, its utility in treating other immune-mediated disorders is being explored.

Abstract
PURPOSE OF REVIEW This article describes the evolution of combination therapy in inflammatory bowel disease and how to determine when combination may not be necessary. RECENT FINDINGS The combination of an immunosuppressive agent with an antibody to tumor necrosis factor has proven to be more effective than monotherapy with either an immunosuppressive agent or an antibody to tumor necrosis factor alone. The emergence of therapeutic drug monitoring has identified the importance of maintaining adequate circulating drug levels and suppressing antibody formation to the biological agent. The concomitant use of an immunosuppressive agent can help effect this. Although this may be optimal therapy in moderately ill patients. I review why there still remains a role for using monotherapy with immunosuppressive agents, as well as consideration of therapy withdrawal. SUMMARY Although combination therapy is the treatment of choice in persons with moderate to severe disease or who have lost response to biological monotherapy, there remains a role for monotherapy with immunosuppressive agents. Though the newer biological therapies are mostly not used in combination, this may be a future approach considering their response rates are also correlated with higher drug levels. Many persons with inflammatory bowel disease can remain well on an immunosuppressive agent alone and some can even maintain a longstanding remission off all therapy.

Abstract
Secukinumab is a human monoclonal antibody that selectively targets interleukin-17A and has been demonstrated to be highly efficacious in the treatment of moderate to severe plaque psoriasis, starting at early time points, with a sustained effect and a favorable safety profile. Biotherapeutics--including monoclonal antibodies (mAbs)--can be immunogenic, leading to formation of anti-drug antibodies (ADAs) that can result in unwanted effects, including hypersensitivity reactions or compromised therapeutic efficacy. To gain insight into possible explanations for the clinically observed low immunogenicity of secukinumab, we evaluated its immunogenicity potential by applying 2 different in vitro assays: T-cell activation and major histocompatibility complex-associated peptide proteomics (MAPPs). For both assays, monocyte-derived dendritic cells (DCs) from healthy donors were exposed in vitro to biotherapeutic proteins. DCs naturally process proteins and present the derived peptides in the context of human leukocyte antigen (HLA)-class II. HLA-DR-associated biotherapeutic-derived peptides, representing potential T-cell epitopes, were identified in the MAPPs assay. In the T-cell assay, autologous CD4(+) T cells were co-cultured with secukinumab-exposed DCs and T-cell activation was measured by proliferation and interleukin-2 secretion. In the MAPPs analysis and T-cell activation assays, secukinumab consistently showed relatively low numbers of potential T-cell epitopes and low T-cell response rates, respectively, comparable to other biotherapeutics with known low clinical immunogenicity. In contrast, biotherapeutics with elevated clinical immunogenicity rates showed increased numbers of potential T-cell epitopes and increased T-cell response rates in T-cell activation assays, indicating an approximate correlation between in vitro assay results and clinical immunogenicity incidence.

Abstract
Secukinumab (Cosentyx™) is a human monoclonal IgG1k antibody that has been developed to target and block the actions of IL-17A. It is known that this cytokine is elevated in lesions of psoriasis. Interleukins in the Th17 pathway play a pivotal role in the pathogenesis of psoriasis and have thus become targets for recent biologic drug development. As a monoclonal antibody immune modulator, secukinumab exhibits the expected pharmacokinetic properties of slow subcutaneous absorption, low clearance, and long half-life, although formal studies examining the impact of impaired hepatic or renal function on the overall pharmacokinetic profile have not been conducted. Both Phase II and III clinical trials have demonstrated the effectiveness of secukinumab in the treatment of moderate-to-severe plaque psoriasis, psoriatic arthritis, rheumatoid arthritis, ankylosing spondylitis, and noninfectious uveitis. In June 2015, secukinumab was approved by the US Food and Drug Administration for the treatment of adults with moderate-to-severe plaque psoriasis, with a wealth of clinical trials showcasing its efficacy in improving psoriasis area and severity index scores, and it is superior to other comparable biologics on the market, including the TNF inhibitor etanercept. As such, this review focuses on the marquee clinical trials involving secukinumab treatment of plaque psoriasis, while also exploring this drug's efficacy in treating patients with psoriatic arthritis, a disease that has a well-documented comorbidity in patients diagnosed with moderate-to-severe plaque psoriasis. Finally, the safety and tolerability of this drug in a variety of clinical trials to date have also been reviewed, and will undoubtedly have a large impact on this drug's postmarketing surveillance and future studies regarding its long-term safety.
