Successful management of treatment resistant nail psoriasis with tildrakizumab

Short-term efficacy of tildrakizumab on difficult-to-treat areas: a real-world experience

BACKGROUND

Novel biologics targeting the IL23/T-17 axis, such as tildrakizumab, have been developed to treat psoriasis. There is limited evidence on the use of tildrakizumab for the treatment of psoriasis in difficult-to-treat areas.

OBJECTIVE

Our aim was to evaluate the short-term efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis and with the involvement of difficult-to-treat areas.

METHODS

A multicentric retrospective study was conducted on patients who initiated tildrakizumab between July 2022 and July 2023. Psoriasis Area and Severity Index (PASI), Psoriasis Scalp Severity Index (PSSI), Palmoplantar Psoriasis Area and Severity Index (ppPASI), and Nail Psoriasis Severity Index (NAPSI) were measured at baseline and after 16 weeks. The percentages of achieving a PASI75, PASI90, or PASI100 response were assessed. Dermatology Life Quality Index (DLQI) and Itch Visual Analog Scale (VAS) were measured simultaneously. Data about potential safety issues and adverse events were collected.

RESULTS

A total of 76 patients were included, and 59 (77.6%) were affected by psoriasis localized to the scalp (n = 32), palmoplantar locations (n = 13), or nails (n = 14). The mean PASI score decreased from 16.5 ± 9.8 at baseline to 1.9 ± 1.6 after 16 weeks. Tildrakizumab treatment resulted in the improvement of PSSI (19.9 ± 10.7 to 2.7 ± 4.2), ppPASI (15.4 ± 6.9 to 1.9 ± 2.3), and NAPSI (20.3 ± 16.9 to 7.6 ± 10.8) from baseline to 16 weeks, respectively. DLQI and Itch VAS also showed marked improvement.

CONCLUSIONS

Tildrakizumab is a valuable option for treating difficult-to-treat psoriasis and pruritus, with rapid onset of action.

52-Week Mid-term Efficacy of Tildrakizumab in Moderate-to-severe Psoriasis: A Real-life Multicenter Experience

Tildrakizumab is an IL-23-inhibitor that has been approved to treat plaque psoriasis. However, few reports have become available on its efficacy profile in the real-world. Our objective was to study the mid-term efficacy of tildrakizumab in patients with moderate-to-severe psoriasis in the Spanish routine clinical practice setting. This was a retrospective multicenter study that included a total of 91 psoriatic patients on tildrakizumab. The mean Psoriasis Area and Severity Index (PASI) was 9.09 (SD, 5.30). The overall tildrakizumab survival rate was 93.47% for a mean treatment exposure of 30.18 weeks (SD, 16.57). No drug discontinuation was associated with drug tolerability, or adverse reactions. Absolute PASI ≤3 was reached by 91.3% and 96.5% of the patients on weeks 28 and 52, respectively. Response was not impacted by weight, age (>65), metabolic syndrome, presence of arthritis, or previous number of biological therapies used. Based on our own experience tildrakizumab is an effective strategy to treat plaque psoriasis and difficult-to-treat-areas.

Effectiveness and Safety After a Switch to Tildrakizumab: A Real World Multicenter Italian Study in Psoriasis

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. Psoriasis Area Severity Index (PASI) and Body Surface Area (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 Dermatology Life Quality Index (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 <0.001) with further increase at week 48. The effectiveness was confirmed also by DLQI assessment, with a significant decrease at week 12 and even more at week 48 (P <0.001).

CONCLUSIONS

This study confirms the effectiveness of tildrakizumab in daily clinical practice in patients with moderate-to-severe plaque psoriasis.

Nail Psoriasis: An Updated Review of Currently Available Systemic Treatments

Background

Nail psoriasis (NP) has a prevalence that ranges from 10 to 82% among patients with psoriasis (PsO) and is one of the most common difficult to treat site of psoriasis. We performed a thorough review of the literature, exploring evidence regarding all available NP systemic treatments, describing also in detail NP dedicated clinical trials.

Methods

A literature search was conducted in PubMed and Embase prior to February 2023 using a combination of the terms "nail" AND "psoriasis" AND "systemic therapy" AND/OR "systemic treatment". A total of 47 original studies and case reports were reviewed in this article.

Results

Systemic therapies should be considered when the disorder involves more than 3 nails, has extensive skin and joint involvement, and has a significant impact on QoL, due to their best long-term efficacy. In detail, conventional and biologic systemic drugs demonstrated efficacy in recent trials, including acitretin, methotrexate, cyclosporine, apremilast, adalimumab, infliximab, etanercept, certolizumab, golimumab, ustekinumab, secukinumab, ixekizumab, brodalumab, bimekizumab, guselkumab, risankizumab and tildrakizumab.

Conclusion

Several therapies have demonstrated efficacy and safety in the treatment of NP; however, the choice of treatment depends not only on the severity of the nail involvement, but also on whether PsA is present, the patient's comorbidities other than PsA, previous treatment history, and the patient's drug preferences.

Updates in treatment and impact of nail psoriasis

INTRODUCTION

Nail psoriasis is an inflammatory disorder without a potential scarring outcome, but the nail signs, even the milder ones, can cause discomfort to patients and severely affect their quality of life. Nail psoriasis may be associated with psoriatic arthritis and when it starts during infancy, it may be a predictor of a more severe disease course in adulthood. All these issues contribute to the high economic burden of psoriasis.

AREAS COVERED

Nail psoriasis is notoriously difficult to treat, even though new treatments are in continuous development. This paper provides an update on new treatments and address the current gaps in care of nail psoriasis.

EXPERT OPINION

A better understanding of the disease pathogenesis and more 'real-life' studies will definitely be helpful to improve treatment results. A lower level of heterogeneity should be advisable among trials when evaluating nail psoriasis. Moreover, the relationship between nail psoriasis and psoriatic arthritis should be the focus of unbiased studies in order to better define the real risk that nail psoriasis patients have to develop arthritis.

Drug safety evaluation of tildrakizumab for psoriasis: a review of the current knowledge

INTRODUCTION

Psoriasis is a chronic inflammatory skin disease that may have an important negative impact on a patient's quality of life. Biological agents deeply changed the management of its moderate-to-severe forms. Interleukin-23 inhibitors represent the latest biologics class approved for the treatment of moderate-to-severe psoriasis. In particular, tildrakizumab, the latest available anti-interleukin-23 on the Italian market, is a humanized monoclonal antibody specifically targeting the p19 subunit of IL-23.

AREAS COVERED

The objective of this review is to evaluate the safety profile of tildrakizumab in moderate-to-severe psoriasis patients. A literature review included articles until July 2022.

EXPERT OPINION

Our analysis showed tildrakizumab as a generally safe option for the treatment of psoriasis, with most of the reported adverse events being classified as mild or moderate, and rarely requiring treatment discontinuation. Furthermore, in line with other interleukin-23 inhibitor, no concerns have been raised for tildrakizumab in regard to inflammatory bowel diseases, which represent a significant comorbidity to investigate before starting other biologics (IL-17 inhibitors). However, more real-life long-term data are needed to confirm trial results to further confirm tildrakizumab as a generally safe treatment option for psoriasis.

Efficacy of Tildrakizumab for the Treatment of Difficult-to-Treat Areas: Scalp, Nail, Palmoplantar and Genital Psoriasis

Tildrakizumab, an IL-23 inhibitor, is effective and safe for the improvement of moderate-to-severe chronic plaque psoriasis. However, little evidence is available on the use of this biologic in psoriasis in difficult-to-treat locations. In this retrospective analysis, we treated patients with 100 mg tildrakizumab at Day 0, after 4 weeks and every 12 weeks thereafter. Disease severity and treatment response was assessed by the Psoriasis Area and Severity Index (PASI), the static Physician’s Global Assessment of Genitalia (sPGA-G), the Psoriasis Scalp Severity Index (PSSI), Nail Psoriasis Severity Index (NAPSI) and the Palmoplantar Psoriasis Area and Severity Index (ppPASI) at baseline and after 4, 12 and 28 weeks. We followed 18 patients (mean age 49.1 ± 12.7 years, 61.1% male) with psoriasis localized to the genital region (N = 7), scalp (N = 6), nails (N = 5) and palmar/plantar areas (N = 7). PASI score decreased from 11.5 at baseline to 3.1 and 2.4 at 12 and 28 weeks. Tildrakizumab treatment decreased sPGA-G (3.3 to 0.2), PSSI (36.2 to 2.7), NAPSI (48.4 to 15.7) and ppPASI (5.3 to 0) from baseline to 28 weeks, respectively. Data from this real-life retrospective analysis shows that tildrakizumab is an effective option for the management of psoriasis in difficult-to-treat areas.

Tildrakizumab for treatment of moderate to severe psoriasis: an expert opinion of efficacy, safety, and use in special populations

INTRODUCTION

Tildrakizumab is a monoclonal antibody that targets the p19 subunit of IL-23, a crucial cytokine for Th17 cells. Tildrakizumab has been assessed in several Phase I, II, and III clinical trials and is approved for treatment of adults with moderate to severe plaque psoriasis who are indicated for systemic therapy.

AREAS COVERED

The available evidence on the efficacy, safety, and use of tildrakizumab in special populations was evaluated by 14 experts who critically reviewed the current literature.

EXPERT OPINION

Tildrakizumab has good efficacy that lasts for at least 5 years in patients with moderate to severe psoriasis, and appears to be safe and well tolerated in the long-term with no apparent dose-related differences in adverse events, a low incidence of discontinuation due to adverse events, and no evidence of increased risk of malignancies. The safety and the efficacy of tildrakizumab has also been confirmed in special populations such as those with inflammatory bowel disease, cardiovascular disease, metabolic syndrome, and advanced age. Early intervention with IL-23-inhibitors, such as tildrakizumab, may help to control symptoms and change the long-term course of the disease in patients affected by plaque psoriasis, while improving the quality of life and potentially minimizing the risk of developing comorbidities.
