INTRODUCTION: Plaque psoriasis is a chronic condition that may impact patients work productivity. Tildrakizumab, an interleukin-23 p19 inhibitor, is approved for treatment of moderate-to-severe plaque psoriasis in adults. However, the effect of tildrakizumab treatment on work productivity in patients with psoriasis is not well characterized. METHODS: In this multicenter, open-label, uncontrolled phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. Patients completed the Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI:PSO) at baseline and every 12 weeks from week 16 through week 64. The following four domains of the WPAI:PSO were examined: absenteeism (percentage of time missed from work due to psoriasis), presenteeism (percentage reduction of productivity while at work due to psoriasis), total activity impairment (percentage impairment in activities other than work due to psoriasis), and total work productivity impairment (total percentage of work impairment from both absenteeism and presenteeism due to psoriasis). Missing data were not imputed. RESULTS: Of the 55 patients enrolled, 31 patients completed all domains of the WPAI:PSO at week 64. From baseline to week 64, respectively, mean ± standard deviation (SD) scores improved for presenteeism (20.5 ± 21.7 to 2.6 ± 5.8; P

Vitiligo is a chronic depigmenting disorder that significantly impacts the quality of life of patients. Though there have been significant advancements in targeted therapies in skin diseases such as psoriasis or eczema, the progress in the treatment of vitiligo has been slow, with minimal studies assessing the effect of biologics, though there has been recent evidence of the effectiveness of JAK inhibition. This paper reviews the published case reports and studies for the use of systemic targeted therapies including biologics and JAK inhibitors in vitiligo. [ABSTRACT FROM AUTHOR]

Objective: Tildrakizumab, an anti–interleukin-23 p19 monoclonal antibody, is approved for the treatment of adults with moderate-to-severe plaque psoriasis. Limited evidence is available regarding the effects of tildrakizumab on patient-reported symptoms and satisfaction. This report describes the secondary endpoints of patient-reported symptoms and treatment satisfaction over 64 weeks in patients with moderate-to-severe plaque psoriasis treated with tildrakizumab in a Phase IV, real-world study. Methods: In this uncontrolled, open-label study (NCT03718299), patients received tildrakizumab 100 mg at baseline, Week (W)4, and every 12 weeks thereafter to W52, with the final assessment at W64. Patient-reported secondary endpoints included numerical rating scale (NRS) scores for itch, pain, and scaling, and treatment satisfaction measured by 3 rating scales (Treatment Satisfaction Questionnaire for Medication [TSQM], Tildrakizumab Overall Satisfaction, and Patient Happiness with Psoriasis Control instrument) through W64. Results: Of the 55 patients enrolled, 45 were assessed at W64. Mean NRS scores for itch, pain, and scaling all decreased from baseline beginning as early as W4 with maintenance through W64 (P≤0.001). Treatment satisfaction was positive throughout treatment based on all 3 measures. Mean±SD TSQM domain scores increased from 59.5±17.0 at W4 to 79.5±20.1 at W64 for Effectiveness and from 72.7±18.6 to 81.9±20.5 for Global Satisfaction. Limitations: The study is small and lacks a comparator arm. Conclusion: Tildrakizumab treatment improved patient-reported symptoms in patients with moderate-to-severe plaque psoriasis in a real-world setting and was associated with high levels of treatment satisfaction over 64 weeks.

Background/Objectives: Psoriasis (PsO) is a chronic inflammatory skin disease that severely impacts patients' quality of life (QoL). Its global prevalence is about 2%, with significant regional variations. PsO manifests in the form of erythematous and scaly plaques, causing intense pruritus and discomfort and limiting daily activities. The condition often includes comorbidities such as psoriatic arthritis, cardiovascular diseases, and metabolic syndrome, further deteriorating QoL. Psychological well-being is notably affected, with high levels of depression and anxiety due to the visible lesions, leading to social stigma and isolation. QoL indexes like WHO-QoL and SF-36 assess various well-being aspects, while patient-reported outcomes (PROs) provide a comprehensive understanding of PsO's impact. However, there are no universally shared PROs in outpatient practice to fully understand the impact of the disease and associated therapies. This study aims to evaluate differences between DLQI and WHO-5 in adult patients with moderate-to-severe PsO treated with tildrakizumab 100 mg or 200 mg. Methods: The study was conducted at the University Hospital of Siena, Italy, from May 2023 to April 2024. Data from 15 patients treated with tildrakizumab 200 mg and 15 patients treated with tildrakizumab 100 mg, observed for at least 28 weeks, were recorded. Demographic data, PASI, DLQI, and WHO-5 scores were analyzed. Patients in the 100 mg group (G100) were selected to match the demographic characteristics of the 200 mg group (G200). Reduction rates of DLQI and WHO-5 were assessed at baseline values and after 4, 16, and 28 weeks. Results: Both groups experienced improvements in QoL. The group treated with 200 mg showed more pronounced and rapid reductions in DLQI and WHO-5 scores compared to the 100 mg group. WHO-5 demonstrated faster improvements in overall well-being than DLQI, indicating its greater sensitivity to changes in mental well-being and overall QoL. No differences in adverse events were observed between the two groups, with no major adverse events reported. Conclusions: In our study, WHO-5 proved more sensitive than DLQI in capturing well-being changes in PsO patients treated with tildrakizumab. However, a combined use of both WHO-5 and DLQI questionnaires should be encouraged in clinical practice. Furthermore, this study confirmed the superior QoL improvement associated with tildrakizumab 200 mg compared to 100 mg. Future research should explore the long-term impact on QoL and comparative effectiveness among other biologic therapies in diverse patient populations. [ABSTRACT FROM AUTHOR]

Introduction: The efficacy and safety of tildrakizumab for the treatment of plaque psoriasis were demonstrated by randomized clinical studies, but the reappraisal of prolonged experiences in the clinical practice helps to optimize the use of this biologic drug. The aim of this study was to evaluate the long-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the real world. Methods: This is a long-term retrospective observational study in a real-life setting. Overall, 136 adult patients with moderate-to-severe plaque psoriasis and treated with tildrakizumab were included. Results: One hundred percent reduction of Psoriasis Area Severity Index (PASI100) was reached by 21.7% of patients at 4 weeks of therapy and by 51.2% at week 16, and the proportion of patients with this improvement was between 66.9% and 64.5% from 36 weeks to 3 years. The mean PASI of the cohort progressively improved from 12.6 at baseline to 1.8 at week 36 and was stable at 1 year, 2 years and 3 years. We could not confirm a previous observation that patients naïve to biologic had a better response, but we observed that those with a short history of psoriasis had a higher probability of 90% PASI reduction (PASI90) or PASI 100 within 36 weeks, suggesting that early treatment could be useful. Conclusion: This long-term observation in the real life of patients with moderate-to-severe plaque psoriasis receiving tildrakizumab 100 mg showed that PASI100 can be obtained in a high proportion of patients by week 36 and be maintained for up to 3 years.

Characteristic islands of sparing are usually observed. A standardised therapeutic approach is lacking owing to the infrequent occurrence of this disease. However, anti-interleukin (IL)-17 and anti-IL-23 therapies have recently emerged as effective therapies in patients affected by PRP, with improvements in severity scores, change in severity of erythema, scaling, and thickness of lesions. Here, we report a 43-year old, female breast cancer who developed severe refractory PRP, which greatly impacted her quality of life. The patient experienced a marked improvement after treatment with tildrakizumab. Treatment was stopped after one year, and the three-year follow-up did not show relapse. In conclusion, 52- week treatment with tildrakizumab, an IL-23 antagonist, proved to be a favourable treatment option for PRP, leading to good patient adherence, improvement in quality of life, and long-term follow-up without relapse.Keywords: pityriasis rubra pilaris, treatment, tildrakizumab, breast cancer

Purpose of the article: Interleukin-23 inhibitors, such as tildrakizumab, have emerged as safe and effective options for the management of psoriasis. Yet their efficacy in elderly patients (aged 65years or more), particularly in those with difficult-to-treat areas involvement, remains insufficiently explored. We conducted this real-life retrospective multicentric observational study to assess the effectiveness of tildrakizumab in elderly patients with moderate-to-severe psoriasis, with involvement of difficult-totreat areas. Materials and methods: We enrolled forty-nine patients aged 65years old or more (mean age 73.1±6.0), all treated with tildrakizumab for at least 28weeks. The effectiveness of tildrakizumab was assessed by Static Physician’s Global Assessment of Genitalia (sPGA-G), fingernail-PGA (f-PGA), palmoplantar PGA (pp-PGA), scalp-specific PGA (sc-PGA), and Psoriasis Area and Severity Index (PASI) scores. Results: Significant improvements in PASI scores were observed within 28weeks of treatment, with 77.5%, 60%, and 45.2% of patients achieving PASI75, PASI90, and PASI100, respectively. The mean PASI decreased significantly from baseline (13.6±9.9) to 1.3±1.7 at week 28. More than 90% of patients had clear sPGA-G and pp-PGA scores and over 70% had clear f-PGA and sc-PGA scores after 28weeks. Conclusions: Our findings suggest that tildrakizumab could be a valuable option for the treatment of elderly patients, including those with difficult-to-treat areas involvement.

Purpose: Tildrakizumab is a selective inhibitor of IL-23 approved for the treatment of moderate-tosevere plaque psoriasis in two dosages. We conducted a 16-week multicenter retrospective study to compare the effectiveness and safety of tildrakizumab 200mg versus tildrakizumab 100mg in patients with a high disease burden or high body weight. Materials and methods: Our retrospective study included 134 patients treated with tildrakizumab 200mg and 364 patients treated with tildrakizumab 100mg from 28 Italian Dermatology Units affected by moderate-to-severe plaque psoriasis. The patients had a body weight above 90kg or a high disease burden (Psoriasis Area and Severity Index [PASI]≥16 or the involvement of difficult-to-treat areas). We evaluated the effectiveness of tildrakizumab at the week-16 visit in terms of PASI90, PASI100 and absolute PASI ≤ 2. Results: After 16weeks of treatment with tildrakizumab 200mg, PASI90 was reached by 57.5% of patients and PASI100 by 39.6% of patients. At the same time point, 34.3% and 24.2% of patients treated with tildrakizumab 100mg achieved PASI90 and PASI100, respectively. Conclusions: Our data suggest that tildrakizumab 200mg has better effectiveness than tildrakizumab 100mg in patients with a body weight ≥ 90kg and a high disease burden. [ABSTRACT FROM AUTHOR]

Background: Tildrakizumab is an interleukin-23p19 inhibitor, approved by the Food and Drug Administration for the management of moderate-to-severe plaque psoriasis. Purpose: This review aims to describe the dermatological implications and applications of tildrakizumab. Methods: PubMed and Google Scholar were searched for scholarly articles related to tildrakizumab and its utility in dermatology using the search terms “Tildrakizumab” AND “Psoriasis” AND “other dermatological disorders.” Results: Tildrakizumab is a valuable biologic agent for the management of psoriasis. It has also been successfully used for other dermatologic disorders such as hidradenitis suppurativa, lichen planus, pityriasis rubra pilaris, lupus erythematosus tumidus, and pyoderma gangrenosum. Conclusion: Tildrakizumab’s usage is not limited to psoriasis. Its benefit extends to many more dermatologic conditions. Besides, it has an acceptable safety profile.

Detecting the association of genetic variants to the response of biological therapy represents an important advance in developing a personalized therapy. The aim of this work was to study the association of polymorphisms with an optimal response to tildrakizumab in patients with psoriasis in a real‐life clinical practice. Ninety patients with plaque psoriasis recruited from—Spanish hospitals receiving tildrakizumab for at least 24 weeks were genotyped for 180 polymorphisms. Optimal response to tildrakizumab was evaluated by absolute PASI ≤1 at 6 and 12 months. Polymorphisms corrected for weight and disease duration with an FDR <0.15 were included in a multiple regression model. Sixty three percent of patients achieved an absolute PASI ≤1 at 6 months, while 71% did so after 12 months. Disease duration (>27 years) and weight (>76 kg) were associated with treatment response; after correcting by these factors, no association (FDR >0.15) was found for any polymorphism and response to tildrakizumab at 6 months. The analysis at 12 months identified the genotype GG for rs610604 (TNFAIP3), CT for rs9373839 (ATG5), and delCTGT/delCTGT for rs72167053 (PDE4D) as risk factors to not achieve an optimal response (PASI ≤1), while CT for rs708567 (IL17RC) was protective, independently of weight and disease duration (FDR <0.15). The final multivariable model at 12 months showed an AUC of 0.90 (95% CI 0.82 to −0.98). We identified a set of polymorphisms that could be helpful to identify psoriatic patients with an optimal response to tildrakizumab at 12 months in real‐world practice conditions.

Background: Tildrakizumab, the IL-23 inhibitor, is used to treat plaque psoriasis and psoriatic arthritis. Many studies have reported adverse drug reactions (ADRs) associated with Tildrakizumab. Objective: The aim of this study was to describe ADRs associated with Tildrakizumab monotherapy by mining data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). Methods: The signals of Tildrakizumab-associated ADRs were quantified using disproportionality analyses such as the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multiitem gamma Poisson shrinker (MGPS) algorithms. Results: A total of 10,530,937 reports of ADRs were collected from the FAERS database, of which 1,177 reports were identified with tildrakizumab as the "primary suspect (PS)". Tildrakizumab-induced ADRs occurred against 27 system organ classes (SOCs). A total of 32 significant disproportionality Preferred Terms (PTs) conformed to the algorithms. Unexpected significant ADRs such as coronavirus infection, herpes simplex, diverticulitis, atrial fibrillation and aortic valve incompetence were also possible. The median time to onset of Tildrakizumabassociated ADRs was 194 days (interquartile range [IQR] 84-329 days), with the majority occurring, within the first 1 and 3 months after initiation of Tildrakizumab. Conclusion: This study identified a potential signal for new ADRs with Tildrakizumab, which might provide important support for clinical monitoring and risk prediction. [ABSTRACT FROM AUTHOR]

Scalp psoriasis is common and difficult to treat. To evaluate efficacy and safety of tildrakizumab for the treatment of scalp psoriasis. In this Phase 3b, randomized, double-blind, placebo (PBO)-controlled study (NCT03897088), patients with moderate-to-severe plaque psoriasis affecting the scalp (Investigator Global Assessment modified [IGA mod] 2011 [scalp] ≥3, Psoriasis Scalp Severity Index [PSSI] ≥12, ≥30% scalp surface area affected) received tildrakizumab 100 mg or PBO at W0 and W4. The primary endpoint was IGA mod 2011 (scalp) score of "clear" or "almost clear" with ≥2-point reduction from baseline at W16 (IGA mod 2011 [scalp] response). Key secondary endpoints were PSSI 90 response at W12 and W16 and IGA mod 2011 (scalp) response at W12. Safety was assessed from adverse events. Of patients treated with tildrakizumab (n = 89) vs PBO (n = 82), 49.4% vs 7.3% achieved IGA mod 2011 (scalp) response at W16 (primary endpoint) and 46.1% vs 4.9% at W12; 60.7% vs 4.9% achieved PSSI 90 response at W16 and 48.3% vs 2.4% at W12 (all P <.00001). No serious treatment-related adverse events occurred. Only short-term data are presented. Tildrakizumab was efficacious for the treatment of scalp psoriasis with no new safety signals.

For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. Studies regarding infection rates after vaccination are lacking. Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases. [ABSTRACT FROM AUTHOR]

Treatment of psoriasis associated with human immunodeficiency virus (HIV) infection is challenging due to the high incidence of comorbidities and polypharmacy and the lack of evidence on the efficacy and safety of available drugs in these patients. Therefore, clinical or anecdotal reports provide useful indications for therapy decision-making. A 64-year male with plaque psoriasis (Psoriasis Area and Severity Index=14.3) infected with HIV for 4 years, with hypercholesterolemia, hypertension, and impaired quality of life (Dermatology Life Quality Index=14) was resistant to topical therapy and acitretin. Tildrakizumab 200 mg was started, obtaining Psoriasis Area and Severity Index=0 at week 16 which was maintained after 13 months of follow-up. No adverse event was reported, and immune cell levels were unchanged. This is the first report on the treatment of psoriasis with tildrakizumab in an HIV+ patient. A literature search showed that prior to this patient, 38 HIV+ subjects had been treated with anti-cytokine agents for psoriasis.

Despite its effectiveness and safety have been widely reported by clinical trials and real-life experiences, data regarding its use on patients who previously failed anti-IL17 (brodalumab, ixekizumab, bimekizumab and/or secukinumab) are scant. Therefore, further studies on this topic would be beneficial for clinicians in guiding the selection of biologic shifting, considering that anti-IL23, − 12/23, and -IL17 partially share their therapeutic targets. In this context, we performed a 28-week, single-center, real-life, retrospective study, with the aim of assessing the efficacy and safety of tildrakizumab in patients who previously failed anti-IL17, also focusing the attention on psoriasis located in difficult-to-treat areas (scalp, palms or soles, fingernails, genitals). A total of 23 patients (12 male, 52.2%; mean age 52.8 ± 12.4 years) were enrolled. Of these, 11 (47.8%) failed secukinumab, 7 (30.4%) ixekizumab, 3 (13.0%) brodalumab, 1 (4.3%) both secukinumab and ixekizumab and 1 (4.3%) bimekizumab. At baseline, mean PASI and BSA were 12.8 ± 5.9 and 18.7 ± 9.6, respectively. At W16 PASI75 and PASI90 response were achieved by 15 (65.2%), and 9 (39.1%) patients, respectively, whereas 19 (82.6%) and 13 (56.6%) subjects reached these scores at W28. One (4.3%) case of primary inefficacy and 1 (4.3%) case of secondary inefficacy were assessed. Finally, no severe adverse events were collected. Tildrakizumab seems to be a valuable option in selected patients with psoriasis unresponsive to anti-IL17, suggesting that prior exposure to biological therapies seem not directly affect its effectiveness.Keywords: Tildrakizumab, psoriasis, real-life, anti-IL23

Abstract Introduction Plaque psoriasis is a chronic condition that may impact patients’ work productivity. Tildrakizumab, an interleukin-23 p19 inhibitor, is approved for treatment of moderate-to-severe plaque psoriasis in adults. However, the effect of tildrakizumab treatment on work productivity in patients with psoriasis is not well characterized. Methods In this multicenter, open-label, uncontrolled phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. Patients completed the Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI:PSO) at baseline and every 12 weeks from week 16 through week 64. The following four domains of the WPAI:PSO were examined: absenteeism (percentage of time missed from work due to psoriasis), presenteeism (percentage reduction of productivity while at work due to psoriasis), total activity impairment (percentage impairment in activities other than work due to psoriasis), and total work productivity impairment (total percentage of work impairment from both absenteeism and presenteeism due to psoriasis). Missing data were not imputed. Results Of the 55 patients enrolled, 31 patients completed all domains of the WPAI:PSO at week 64. From baseline to week 64, respectively, mean ± standard deviation (SD) scores improved for presenteeism (20.5 ± 21.7 to 2.6 ± 5.8; P

Background: Real-world evidence plays a pivotal role in validating the efficacy of biologic drugs beyond the controlled environment of randomized trials. This study aimed to evaluate the effectiveness of tildrakizumab in treating moderate-to-severe psoriasis within a real-world setting over a 52-week period in Portugal. Methods: This multicentric, prospective, observational study included adult patients with moderate-to-severe psoriasis. All participants received tildrakizumab 100 mg at weeks 0 and 4, followed by a maintenance dose every 12 weeks, and were monitored for 52 weeks. Primary endpoints were determined based on Psoriasis Area and Severity Index (PASI) assessments at baseline, 16 (±2) weeks, 28 (±2) weeks and 52 (±2) weeks. Results: A total of 54 patients were enrolled in the study (56% men, mean age of 50.3 ± 14.4 years). Half of the sample (n=27) had no prior experience with biologic treatments. About 74% of patients (n=40) presented at least one comorbidity during the study, with psoriatic arthritis being the most prevalent (29.6%). By week 52, there was a significant decrease in the mean PASI from 17.8±10.3 at baseline to 1.3±1.9 (p

Introduction: Psoriasis is a chronic immune-mediated disease that can be challenging to treat, especially in patients with severe disease or high body weight. Tildrakizumab is a monoclonal antibody which inhibits IL-23, approved for moderate-to-severe psoriasis with a standard 100 mg dose. A 200 mg dose may provide greater efficacy for patients over 90 kg or with high disease burden.Methods: This multicenter, prospective study evaluated the effectiveness and safety of tildrakizumab 200 mg in patients with moderate-to-severe psoriasis, focusing on those with specific challenges: body weight over 90 kg, baseline PASI ≥20, and difficult-to-treat areas. The study also compared bio-naive versus bio-experienced and male versus female patients. Adults received tildrakizumab 200 mg subcutaneously at weeks 0 and 4, then every 12 weeks.Results: Clinical improvements were assessed using PASI, DLQI, genital PASI, and NAPSI scores. After 24 weeks, the mean PASI score dropped from 14.6 to 0.4, with PASI 90 and PASI 100 scores exceeding 80% (100.0% and 80.3%, respectively). DLQI scores improved from 14.2 to 1.8, and significant improvements were seen in genital PASI and NAPSI scores. No significant adverse events occurred.Conclusions: Tildrakizumab 200 has been shown to be an effective therapeutic option, particularly for patients with high body weight, significant disease burden, and involvement of sensitive areas with no new safety signals.

Background Tildrakizumab is an anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes final primary results of a 64-week real-world study of the effect of tildrakizumab on patients’ health-related quality of life (HRQoL).Materials and methods In this open-label phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. The primary endpoint was improvement from baseline in HRQoL measured by Psychological General Well-Being Index (PGWBI) total score at weeks 28 and 52. Secondary HRQoL endpoints included change from baseline in Dermatology Life Quality Index (DLQI) score through week 64. Missing data were not imputed.Results Of 55 patients enrolled, 45 were assessed at week 64. Mean ± standard deviation (SD) total PGWBI score improved from 78.1 ± 14.1 at baseline to 85.2 ± 12.0 at week 52 (p

AbstractPurpose Tildrakizumab is a selective inhibitor of IL-23 approved for the treatment of moderate-to-severe plaque psoriasis in two dosages. We conducted a 16-week multicenter retrospective study to compare the effectiveness and safety of tildrakizumab 200 mg versus tildrakizumab 100 mg in patients with a high disease burden or high body weight.Materials and methods Our retrospective study included 134 patients treated with tildrakizumab 200 mg and 364 patients treated with tildrakizumab 100 mg from 28 Italian Dermatology Units affected by moderate-to-severe plaque psoriasis. The patients had a body weight above 90 kg or a high disease burden (Psoriasis Area and Severity Index [PASI] ≥ 16 or the involvement of difficult-to-treat areas). We evaluated the effectiveness of tildrakizumab at the week-16 visit in terms of PASI90, PASI100 and absolute PASI ≤ 2.Results After 16 weeks of treatment with tildrakizumab 200 mg, PASI90 was reached by 57.5% of patients and PASI100 by 39.6% of patients. At the same time point, 34.3% and 24.2% of patients treated with tildrakizumab 100 mg achieved PASI90 and PASI100, respectively.Conclusions Our data suggest that tildrakizumab 200 mg has better effectiveness than tildrakizumab 100 mg in patients with a body weight ≥ 90 kg and a high disease burden.

The effectiveness of tildrakizumab was assessed by Static Physician’s Global Assessment of Genitalia (sPGA-G), fingernail-PGA (f-PGA), palmoplantar PGA (pp-PGA), scalp-specific PGA (sc-PGA), and Psoriasis Area and Severity Index (PASI) scores.Results: Significant improvements in PASI scores were observed within 28 weeks of treatment, with 77.5%, 60%, and 45.2% of patients achieving PASI75, PASI90, and PASI100, respectively. The mean PASI decreased significantly from baseline (13.6 ± 9.9) to 1.3 ± 1.7 at week 28. More than 90% of patients had clear sPGA-G and pp-PGA scores and over 70% had clear f-PGA and sc-PGA scores after 28 weeks.Conclusions: Our findings suggest that tildrakizumab could be a valuable option for the treatment of elderly patients, including those with difficult-to-treat areas involvement.

Psoriasis is an inflammatory chronic disease of the skin typically located on the extensor surfaces of the body, and the trunk. Patients with psoriasis can often present multiple characteristics, such as lesions located in difficult-to-treat (DTT) areas or a high severity of the disease, which can negatively affect their quality of life. There is a lack of consensus in identifying the best therapy for these complex patient populations, especially after the failure of one or multiple lines of therapy. In this regard, we report a case series describing patients with psoriasis located in different DTT areas or presenting a high Psoriasis Area and Severity Index score at baseline and treated ineffectively with prior lines of therapy. Finally, patients achieved complete remission following therapy with tildrakizumab 200 mg (anti-IL-23p19), highlighting its potential efficacy in these patient populations.

Abstract Background Tildrakizumab is an interleukin‐23p19 inhibitor approved for the treatment of moderate‐to‐severe plaque psoriasis. The new Dermatology Life Quality Index (DLQI)‐Relevant (DLQI‐R) scoring system avoids the bias in the not relevant response option of the DLQI by adjusting the total score to the relevant items. Objectives To assess the impact of tildrakizumab on health‐related quality of life (HRQoL) in patients with moderate‐to‐severe psoriasis in the reSURFACE 2 phase 3 trial as measured with the original DLQI scoring and with the new DLQI‐R. Methods Post hoc analysis of adult patients with moderate‐to‐severe plaque psoriasis from a double‐blinded, randomized, controlled, 52‐week trial. The presented analysis is based on observed cases. Results At baseline, 31.9%/33.6%/40.0% of patients on tildrakizumab 100 mg/tildrakizumab 200 mg/placebo had ≥1 DLQI item marked as ‘not relevant’. The most frequently ‘not relevant’ items were ‘sport’ (14.0%/13.9%/15.5%) and ‘working/studying’ (13.4%/11.3%/12.9%), in the tildrakizumab 100 mg/tildrakizumab 200 mg/placebo groups, respectively. At baseline, 68.1%/73.0%, 60.3%/63.2% and 62.6%/65.8% of patients on tildrakizumab 100 mg, tildrakizumab 200 mg and placebo had a DLQI > 10/DLQI‐R > 10, respectively. Mean DLQI/DLQI‐R scores at baseline were 14.8/15.5, 13.3/14.1, and 14.1/15.0 in the tildrakizumab 100 mg, tildrakizumab 200 mg and placebo groups, respectively. The median change from baseline in both DLQI and DLQI‐R scores at Week 12 was greater in the tildrakizumab 100 mg and 200 mg groups versus placebo (−10.0, −9.0, −1.0 and −11.0, −9.3, −1.1, respectively). At Week 52, the median change from baseline in DLQI/DLQI‐R was −13.0/−14.0 and −10.0/−10.1 in the tildrakizumab 100 mg and 200 mg groups, respectively. Conclusions Treatment with tildrakizumab resulted in significant and sustained improvements in HRQoL up to Week 52 in patients with moderate‐to‐severe psoriasis. The DLQI‐R provides a more unbiased HRQoL assessment ensuring that those who are unable to work/partake in sport have a truer assessment and opportunity for treatment.

Aim: To review the available evidence on the efficacy and safety profiles of four Interleukin-23 inhibitors in patients with Psoriatic Arthritis. Methods: Several databases were searched till July 2022. A total of 11 RCTs with at least one treatment arm were included. All articles were in English. The primary outcomes were ACR20, HAQ-DI, PASI90, and TEAEs experienced by the patients. Results: Compared to other groups, Guselkumab had the strongest association with ACR20 response (RR: 2.14; 95% CI: 1.84-2.49, p < 0.00001), while a mean change in HAQ-DI (MD: -0.24; 95% CI: -0.41- -0.13, p = 0.0001) and PASI90 (RR: 9.81; 95% CI: 3.18-30.22; p

The management of this condition is challenging as the available treatments show variable results, and the course of the condition is often chronic-recurrent; therefore, it will be necessary for the future to identify new therapeutic targets for HS. In recent years, studies have focused on the development towards new therapeutic targets. The purpose of our review was to perform a comprehensive literature review of real-life data on anti-IL23 (guselkumab, tildrakizumab, and risankizumab) in HS to summarize the existing evidence on the efficacy and safety of these drugs. We selected 64 articles, among which 32 had the characteristics that we were looking for in our review. To date, the positive data expressed in real-life experiences contrast with the three existing Phase 2 studies conducted so far, where it seems that these drugs may be useful only for a subgroup of patients with HS whose features need to be elucidated. Data from Phase 3 studies and other real-life experiences, perhaps more detailed and with higher numbers, will certainly be needed to fully understand the efficacy and safety of this class of drugs.Keywords: hidradenitis suppurativa, anti-IL23, guselkumab, tildrakizumab, risankizumab, real life evidence

Abstract Introduction Plaque psoriasis and hidradenitis suppurativa are chronic inflammatory skin conditions with common pathogenetic pathways. Methods We report the case of a 38-year-old man with 15-year history of psoriasis and hidradenitis suppurativa successfully treated with tildrakizumab for both conditions. After treatment failure to adalimumab, secukinumab, and guselkumab, tildrakizumab therapy was initiated and resulted in complete remission of psoriasis and the achievement of hidradenitis suppurativa clinical response after 40 weeks, without reporting adverse events. These responses were maintained at week 52. Conclusion Tildrakizumab may be an effective and safe therapeutic option for concomitant psoriasis and hidradenitis suppurativa.

Background Clinical trials have shown promising results for interleukin-23 inhibitors in the treatment of psoriasis. The drugs have been used in clinical practice since 2017. Objective To investigate the drug survival and effectiveness of interleukin-23 inhibitors in the treatment of psoriasis and psoriatic arthritis (PsA) in a real-world setting. Methods The study was a retrospective analysis of patients treated with either guselkumab, tildrakizumab, or risankizumab at the Department of Dermatology, Aarhus University Hospital, during the period from June 11 2018, to July 14 2021. Results A total of 80 patients were included. During the study, 19 patients discontinued treatment with an interleukin-23 inhibitor, and mean treatment duration (SD) was 61.4 weeks (43.7). Seventy-six patients (95%) had previous use of ≥1 biologic. One-year drug survival was 81.0%. Among patients, 64.3% achieved a Psoriasis Area and Severity Index (PASI) ≤ 2 at weeks 12–17; 61.3%, at weeks 40–60. There was no statistically significant difference between the drugs regarding the chance of achieving PASI ≤ 2 (p>.05). Twenty-two patients (27.5%) had PsA. Among these, 40.9% and 36.4% achieved complete remission and partial remission, respectively. Conclusions Interleukin-23 inhibitors appear to have high and similar drug survival and effectiveness in patients with difficult-to-treat psoriasis and PsA.

Background Tildrakizumab is an anti–interleukin-23 p19 monoclonal antibody approved for the treatment of adults with moderate-to-severe plaque psoriasis. Little real-world evidence is available regarding the effects of tildrakizumab on patients’ health-related quality of life (HRQoL) and patient-reported symptoms. Objective This real-world study of tildrakizumab evaluated changes in HRQoL and clinical symptoms in patients with psoriasis. Materials and methods In this Week (W)28 interim analysis of a 64-week Phase 4 study (NCT03718299), patients received tildrakizumab 100 mg at W0, W4, and every 12 weeks thereafter. Endpoints were improvement from baseline in Psychological General Well-Being Index (PGWBI), Dermatology Life Quality Index (DLQI), and Itch-, Pain-, and Scaling-Numerical Rating Scale scores through W28. Results Of 55 patients enrolled, 53 were assessed at W28. Mean (standard deviation [SD]) total PGWBI score improved from baseline to W28 (change, 3.7 [12.4]; p = .033), as did the positive well-being (1.0 [2.9]; p = .018) and general health (1.5 [2.2]; p < .001) domain scores. Mean (SD) DLQI score improved by −3.9 (4.3) at W4 and by −7.6 (5.1) at W28 (p < .001). Patient-reported symptoms improved starting at W4 (p < .001). Conclusion Tildrakizumab treatment improved HRQoL and patient-reported symptoms in patients with psoriasis in a real-world setting.

Background Five-year tildrakizumab safety data have been reported as exposure-adjusted incidence rates (EAIRs) of patients with events per 100 patient-years (PYs) of exposure. Objectives To present 5-year safety data from reSURFACE 1/2 phase 3 trials as EAIRs of events per 100 PYs of exposure, and the number needed to harm (NNH) for one adverse event of special interest (AESI) to occur. Methods Pooled analysis from two randomized controlled trials in patients with moderate-to-severe plaque psoriasis (n = 1800). PSOLAR registry was used as safety reference data for NNH estimation. Results Rates of AESI with tildrakizumab were comparable with rates reported in PSOLAR. The NNH for one-year severe infection occurrence was 412 with tildrakizumab 200 mg, and negative for tildrakizumab 100 mg due to lower rates in reSURFACE trials; the NNH for malignancy was 990 for one year with tildrakizumab 100 mg (negative for tildrakizumab 200 mg); and the NNH for major adverse cardiovascular events was 355 for one year with tildrakizumab 200 mg (negative for tildrakizumab 100 mg). Conclusion Tildrakizumab demonstrated a favorable safety profile over 5 years with low rates of AESI, comparable to those of the PSOLAR. Consequently, the NNH for AESI with tildrakizumab were very high or negative due to lower event rates for tildrakizumab.

Introduction: As a form of precision medicine, this study aimed to investigate the specific patient population that would derive the greatest benefit from tildrakizumab, as well as the mechanism of action and efficacy of tildrakizumab in reducing the occurrence of psoriatic arthritis (PsA). Methods: To achieve this, amulti-center, prospective cohort study was conducted, involving a population of 246 psoriasis patients who had not received any systemic therapy or topical finger therapy between January 2020 and April 2023. Two independent clinicians, who were blinded to the study, analyzed nailfold capillary (NFC) abnormalities, such as nailfold bleeding (NFB) and enlarged capillaries, as well as the incidence of new PsA. Additionally, the factors that determined the response of psoriasis after seven months of tildrakizumab treatment were examined. The study also examined the quantity and role of regulatory T cells (Tregs) and T helper 17 cells both pre- and post-treatment. Results: The severity of psoriasis, as measured by the Psoriasis Area and Severity Index (PASI), was found to be more pronounced in the tildrakizumab group (n=20) in comparison to the topical group (n=226). At 7months after tildrakizumab treatment, multivariate analysis showed that those 65 years and older had a significantly better response to treatment in those achieved PASI clear or PASI 2 or less (Likelihood ratio (LR) 16.15, p<0.0001; LR 6. 16, p=0.01). Tildrakizumab improved the number and function of Tregs, which had been reduced by aging. Tildrakizumab demonstrated significant efficacy in improving various pathological factors associated with PsA. These factors include the reduction of NFB, enlargement of capillaries, and inhibition of PsA progression. The hazard ratio for progression to PsA was found to be 0.06 (95% confidence interval: 0.0007-0.46, p=0.007), indicating a substantial reduction in the risk of developing PsA. Discussion: Tildrakizumab's effectiveness in improving skin lesions can be attributed to its ability to enhance the number and function of Tregs, which are known to decline with age. Furthermore, the drug's positive impact on NFB activity and capillary enlargement, both of which are recognized as risk factors for PsA, further contribute to its inhibitory effect on PsA progression.

Psoriasis is a chronic inflammatory skin disease characterized by plaque formation. Interleukin (IL)‐23 is upregulated in psoriatic lesions and is thought to be a major regulator of the Th17 pathway in psoriasis pathogenesis. Three monoclonal antibodies targeting the IL‐23p19 subunit, guselkumab, tildrakizumab, and risankizumab, have been approved for psoriasis therapy. The balance between cytokines IL‐23 and IL‐12 can affect antitumor and pro‐tumor immune activities, and patients with psoriasis may have higher rates of cancer than the general population. Moreover, a chronic inflammatory state typical of psoriasis may induce protumorigenic effects, however, the potential risk of malignancy in patients taking these drugs remains largely unknown. This study investigated the occurrence of malignancies as suspected adverse reactions (SARs) potentially associated with IL‐23 inhibitors by analyzing real‐world data from the European EudraVigilance database. Although indicatory, these real‐world data seem to confirm the potential association between the IL‐23 inhibitors risankizumab and tildrakizumab, and the occurrence of SARs linked to cancer in patients with psoriasis and, according to a gender perspective, they show that this relationship is asymmetrically distributed between women and men, with a clear prevalence of oncologic SARs in men.

Introduction: Tildrakizumab is a humanized IgG1κ monoclonal antibody targeting the p19 subunit of interleukin (IL)-23, approved in 2018 for the treatment of patients with moderate-to-severe chronic plaque psoriasis. Objectives: This study aimed to evaluate the effectiveness, safety and survival of tildrakizumab in the medium term (48 weeks) in psoriatic patients failure to previous biologic treatment in a real world setting. Methods: This was a retrospective, multicenter observational study that included adult patients with moderate-to-severe plaque psoriasis, failure to previous biologic therapy, consecutively treated with tildrakizumab. PASI and BSA values were recorded at baseline, at 12 and 48 weeks of treatment. Safety and tolerability of tildrakizumab were investigated by examining the presence of any adverse events. Results: Overall 51 patients were enrolled. Baseline disease severity was moderate to severe with a mean PASI score of 19.2 ± 8.5, mean BSA of 16 ± 10.4, and mean DLQI of 18.2 ± 6.8. A significant reduction in the mean PASI score was detected at 12 weeks of tildrakizumab therapy (3.5 ± 2.7, p < 0.001), with a further improvement at week 48 (0.6 ± 1.5, p < 0.001). At week 12, there was a great improvement in BSA score for all groups (p

The evidence on treating older patients with psoriasis with modern biologics is scarce. This study compared the efficacy and safety of tildrakizumab among younger and older patients with psoriasis (

The approved biologics targeting interleukin (IL)-23 p19 for the treatment of moderate-to-severe plaque psoriasis, including guselkumab, tildrakizumab, and risankizumab, have generally favorable safety profiles. The aim of the current review is to describe in detail the safety of these selective inhibitors. A literature search was performed using PubMed from inception to 1 November 2022, to identify clinical trials and real-world evidence publications using the keywords "guselkumab," "tildrakizumab," and "risankizumab." Overall, the most common adverse events (AEs) associated with IL-23 p19 inhibitors in clinical trials were nasopharyngitis, headache, and upper respiratory tract infections. Rates of serious AEs and AEs of interest, including serious infections, nonmelanoma skin cancer (NMSC), malignancies excluding NMSC, major adverse cardiovascular events, and serious hypersensitivity reactions, were not increased with long-term use in clinical trials. Selectively targeting IL-23 p19 was also not associated with elevated risk of opportunistic infections, tuberculosis reactivation, oral candidiasis, or inflammatory bowel disease. Results from real-world studies were similar, supporting the safe long-term use of these biologics in a wider population of patients with psoriasis, including older patients, patients for whom multiple biologics failed, and those with comorbidities such as obesity, metabolic syndrome, cardiovascular disease, dyslipidemia, diabetes, hypertension, and psoriatic arthritis. This review is limited by the lack of direct comparisons among therapeutic agents due to differences among study designs and safety data reporting methods. In conclusion, the favorable safety profiles of IL-23 p19 inhibitors support their long-term use in the management of patients with moderate-to-severe psoriasis. [ABSTRACT FROM AUTHOR]

Nowadays, the biological equipment available for the treatment of moderate-to-severe psoriasis is plenty. Anti-interleukin-23 represents the latest class of biologic approved for the management of moderate-to-severe psoriasis. Their efficacy and safety have been assessed through two major sources: clinical trials (CTs) and real-world experiences data (RWE). Notably, the two sources differ from one another, but together, they complement information and current knowledge on both efficacy and safety of biological therapy. We carry out a review on CTs and RWE reports on the latest group of biological approved for moderate-to-severe psoriasis: anti-IL23 (guselkumab, risankizumab, and tildrakizumab).

However, safety concerns still remain, particularly on patient affected by opportunistic infections. In this scenario, the safety of biologic drugs in patient with HBV infection is debated. Globally, screening for hepatitis before starting biological treatment is mandatory as well as a referral to an infectivologist and eventual prophylactic management should be evaluated case by case, also considering risk factors. On the one hand, the use of anti-Tumor Necrosis Factor seems to increase the risk of HBV reactivation, conversely, the use of recently approved classes of biologics [anti-interleukin (IL) 17 and anti-IL23] seems to have a lower risk of HBV reactivation. However, the evidence on the safety of anti-IL23 drugs in patients affected by HBV is scant, particularly for patients undergoing treatment with tildrakizumab. Herein, we report the first case of a female patient affected by moderate-to-severe psoriasis and with chronic HBV infection undergoing prophylaxis, successfully treated with tildrakizumab without reporting hepatitis reactivation. Even if limited, our case seems to confirm available evidence about the safety of anti-IL23, particularly tildrakizumab, on patients with chronic HBV infection undergoing prophylaxis.Keywords: psoriasis, HBV infection, biologic therapy, anti-IL23, tildrakizumab

Background/Objectives: For patients with vulvovaginal lichen planus (VLP), there exists limited data on the comparison between patient quality of life treated with topical and/or systemic treatments. We characterised the treatment outcomes of VLP using the vulvar quality of life index (VQLI) comparing women treated with systemic immunosuppression, including humanised interleukin‐23 monoclonal antibody tildrakizumab, to those treated with topical corticosteroids alone. Methods: A retrospective cohort study is reported from a dermatology practice in Sydney, Australia. Electronic medical records for adult women with a diagnosis of VLP were reviewed identifying 112 subjects. VQLI scores in four domains (symptoms, activities of daily living, anxiety and sexual function) were compared between women able to maintain remission of disease with topical monotherapy to those with recalcitrant disease requiring treatment with conventional systemic immunosuppressants and for those not responding to this treatment, tildrakizumab. Results: At baseline women requiring tildrakizumab treatment had the highest total VQLI score (24.6), whilst women whose disease was maintained on topical treatment had the lowest (19.2). Women treated whilst on tildrakizumab had significant reduced total mean VQLI scores (13.32, 95% CI 8.61–18.01) than when treated with other Systemic (22.00, 95% CI 16.52–27.53; p < 0.001) or topical (21.71, 95% CI 16.13–26.32; p < 0.01). Women treated with tildrakizumab demonstrated statistically significant decreases in mean VQLI scores in all four domains of the VQLI compared to previous scores when on other systemic treatments. Conclusion: We report the largest cohort study to date of adult women with VLP evaluating treatment responses to topical and systemic agents using the VQLI. In women whose VLP did not improve with conventional systemic immunosuppressants, tildrakizumab resulted in statistically significant decrease in mean VQLI scores in all 4 domains, highlighting tildrakizumab as an alternative treatment for VLP.

Tildrakizumab is a humanized IgG1κ monoclonal antibody that selectively targets the p19 subunit of interleukin IL-23, thereby inhibiting the IL-23/IL-17 axis, which is primarily implicated in the immunopathogenesis of psoriasis. Tildrakizumab is approved for the treatment of moderate-to-severe plaque-type psoriasis in adults based on the evidence of two randomized and controlled phase-III clinical trials (reSURFACE 1 and reSURFACE 2). Here, we report our real-life experience treating 53 psoriatic patients (19 female and 34 male) who were administered tildrakizumab every 12 weeks and received follow-ups over 52 weeks. Descriptive and inferential statistical analyses were performed, in particular the Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI) and, if applicable, the Nail Psoriasis Severity Index (NAPSI) and Palmoplantar Psoriasis Physician Global Assessment (PPPGA). These were assessed at baseline and after different timepoints (weeks) during the follow-up period. We described and evaluated demographical and epidemiological characteristics in our cohort group, focusing on comorbidities. In this group, 35.9% of patients were female and 64.1% were male, with 47.1% being smokers and with a mean age of 51.2 years. A total of 37.7% of these patients was affected by scalp psoriasis; regarding comorbidities, hypertension was the most frequent (32.5%), followed by psoriatic arthritis (PsA) (18.60%) and diabetes (13.9%). At week 52, 93%, 90.2% and 77% of patients achieved a PASI reduction ≥75% (PASI 75), PASI 90 and PASI 100, respectively. In addition, NAPSI, PPPGA and DLQI scores were significantly reduced by week 52. In our cohort of complex psoriasis patients, disease remission began at the end of the fourth week of treatment and remained constant from week 16 to week 52. [ABSTRACT FROM AUTHOR]

Background: IL-23 inhibitors are the latest class of biologic drugs approved for moderate-to-severe psoriasis. Objectives: to investigate real-life safety and efficacy of tildrakizumab. Methods: demographic data, medical history, psoriasis disease history, PASI, DLQI, BSA, NAPSI were recorded at weeks 0, 12, 24, 36. Results: PASI, BSA, DLQI and NAPSI all decreased rapidly during the 36 week follow-up period. PASI score reduced from 12.28 to 4.65 by week 12, followed by a further decrease to 1.18 at week 36 Multiple logistic regression showed that smoking, BMI ≥30, ≥3 comorbidities, previous systemic traditional or biologic drugs, psoriatic arthritis nor difficult-to-treat areas influenced the reduction of PASI and NAPSI scores during treatment with tildrakizumab (P >.05). Conclusions: we assessed a good performance of tildrakizumab in patients with multiple comorbidities, multi-failure, elderly patients, and in subjects with psoriatic arthritis.

Psoriasis is a chronic inflammatory disorder that is clinically characterized by scaly cutaneous plaques. New evidence suggests that dysregulation of interleukin (IL)-23, a key cytokine in the T-helper-17 pathway, plays a vital role in the development of psoriatic systemic inflammation. The novel biologic medication tildrakizumab is among the first drugs with specific action against IL-23 that has recently been approved by the United States Food and Drug Administration and the European Medicines Agency for moderate-to-severe psoriasis. Tildrakizumab has been shown in large randomized controlled trials to be effective in improving skin manifestations as well as enhancing quality of life outcomes in patients with psoriasis. Its simple dosing, prolonged duration of action, and mild adverse event profile make it a practical option for patients; however, only a small number of trials have investigated the clinical effectiveness of tildrakizumab, and long-term data regarding the drug's efficacy and safety are currently limited. Hence, further research is needed to better understand the risks and benefits of tildrakizumab. This review summarizes and analyzes phase I, phase II, and phase III clinical trials that investigate the mechanism, pharmacokinetics, efficacy, and safety of tildrakizumab. It also identifies areas in which additional studies are warranted to further elucidate the advantages of tildrakizumab over other biologic therapies.
