BACKGROUND
Today, there are many treatment options available for the management of ulcerative colitis, creating challenges in selecting the most efficacious and cost-effective treatment sequences. Treatments in the anti-tumor necrosis factor alpha (TNFα) therapeutic class, as well as vedolizumab, are widely used and endorsed as first-line options according to treatment guidelines. The aim of this study was to compare treatment sequences involving vedolizumab and the anti-TNFα treatment adalimumab in terms of cost-effectiveness in the treatment of moderately to severely active ulcerative colitis in Italy.
METHODS
A cost-effectiveness model comparing treatment sequences within the Italian National Health Service in terms of costs and quality-adjusted life years (QALYs) with a lifetime horizon was developed. The analysis focused on the relative positioning of vedolizumab and adalimumab, leveraging the results of the landmark head-to-head VARSITY clinical trial as key inputs. The robustness of the results was investigated through a range of sensitivity and scenario analyses.
RESULTS
The strategy of vedolizumab as a first-line advanced therapy followed by adalimumab was associated with higher costs and health benefits compared with first-line adalimumab followed by vedolizumab. The incremental cost-effectiveness ratio was €16,146/QALY, which was found to be robust to changes to inputs associated with areas of high uncertainty.
CONCLUSION
This economic evaluation estimated a 94% probability that vedolizumab as a first-line advanced therapy is cost-effective at a threshold of €33,004/QALY when compared with first-line adalimumab sequences. Using clinical trial evidence to inform the efficacy of second-line treatments estimated that the effectiveness of anti-TNFα treatments is not substantially reduced by vedolizumab exposure.

Monotherapy with a selective Janus kinase (JAK) inhibitor or intensive granulocyte and monocyte adsorptive apheresis (GMA) has been limited to patients with intractable ulcerative colitis (UC). No previous reports have described the efficacy including histopathological evaluations and the safety of combination therapy with upadacitinib (UPA) plus intensive GMA (two sessions per week) for intractable UC showing resistance to conventional agents and adalimumab. This retrospective study evaluated the 10-week clinical and histopathological efficacy of induction combination therapy with UPA plus intensive GMA in patients with intractable UC. Among eight patients (moderate UC, n = 1; severe UC, n = 7) who received combination therapy with UPA plus intensive GMA, 50.0% had achieved clinical remission by 10 weeks. Percentages of patients with histological-endoscopic mucosal improvement and mucosal healing at 10 weeks were 62.5% and 12.5%, respectively. After excluding one patient who discontinued treatment by week 10 because of intolerance for UPA, mean full Mayo score, endoscopic subscore and C-reactive protein concentration at baseline were 11.43 ± 0.37, 3 ± 0 and 1.29 ± 0.70 mg/dL, respectively. Corresponding values at 10 weeks were 2.28 ± 0.77 (P < 0.03), 1.14 ± 0.34 (P < 0.03) and 0.03 ± 0.008 mg/dL (P < 0.05), respectively. Adverse events of herpes zoster, temporary increase in creatinine phosphokinase and anemia were observed in one patient each. One patient discontinued combination therapy at week 4 because of temporary taste abnormality due to UPA. Combination comprising UPA plus intensive GMA appears likely to achieve satisfactory induction of clinical remission and histopathological improvement for patients with intractable UC for whom conventional agents and anti-tumor necrosis factor-α antibody have failed.

PURPOSE
Medication delivery device design impacts treatment satisfaction, adherence, and compliance in patients receiving biologics. This survey assessed autoinjector attributes that are important to patients, and assessed patient perceptions and preferences between an adalimumab biosimilar autoinjector (Hyrimoz SensoReady Pen [SDZ-ADL pen]) and the reference adalimumab autoinjector (Humira Pen [ref-ADL pen]) in patients with rheumatoid arthritis (RA) or Crohn's disease (CD) in Canada.
PATIENTS AND METHODS
In this survey, adult patients were recruited for web-assisted telephone interviews. Patients had ≥ 3 months' experience with the ref-ADL pen and 1-12 months' experience with the SDZ-ADL pen.
RESULTS
The survey included 120 patients with RA (n = 32) or CD (n = 88). Mean experience with the ref-ADL pen was 7 years for RA or 5 years for CD vs 9 months with the SDZ-ADL pen. The most important autoinjector attributes were the ability to use the pen independently and the ease and simplicity of self-injection. When comparing the two autoinjectors, patients significantly preferred the SDZ-ADL pen over the ref-ADL pen for nearly every attribute evaluated, with the greatest differences reported for visual and audible feedback mechanisms, ease of self-injection, and ability to use the device independently. Overall, 82% of patients preferred the SDZ-ADL pen over the ref-ADL pen, with buttonless activation and less injection pain being the main drivers for this preference.
CONCLUSION
Patients with RA or CD indicated a preference for the SDZ-ADL pen over the ref-ADL pen, independent of the duration of use of the pen. The preference for a biosimilar device within 1 year of switching provides reassurance of rapid patient acceptance of biosimilars and may simplify the switching process. These results confirm the importance of ensuring autoinjector design supports independent self-administration of medication and align with previous data showing high patient satisfaction with the SDZ-ADL pen.

BACKGROUND
This study explores prognostic factors influencing Vogt-Koyanagi-Harada (VKH) disease and observes the efficacy and safety of Adalimumab (ADA) in treating recurrence in Vogt-Koyanagi-Harada (VKH) patients.
METHODS
A retrospective study was conducted on all patients diagnosed with VKH disease at Beijing Tongren Hospital between 2020 and 2023. Clinical data included initial and final visual acuity, age, gender, ocular complications, treatment modalities, disease duration, and recurrence frequency.
RESULTS
A total of 62 VKH patients were included, comprising 34 in the acute-resolved group and 28 in the chronic-recurrent group. The mean age of patients in the acute-resolved group was 38.29 ± 15.46 years, while the mean age of chronic-recurrent group had a 49.00 ± 16.43 years. Initial best-corrected visual acuity (BCVA) examination at the first visit showed an average BCVA of 0.64 ± 0.29 logMAR in the acute-resolved group and 1.38 ± 0.54 logMAR in the chronic-recurrent group (p = 0.002). During follow-up, ocular complications were observed in 29.4% of the acute-resolved group patients and 41.7% of the chronic-recurrent group patients (P = 0.006). "Sunset glow fundus" was observed in 23.5% of the acute-resolved group and 64.3% of the chronic-recurrent group patients (P = 0.001). Poor initial BCVA (P = 0.046) and the occurrence of "sunset glow fundus" (P = 0.040) were significantly associated with progression to the chronic recurrent phase. Logistic regression analysis revealed that older age at onset (P = 0.042) and the occurrence of "sunset glow fundus" (P = 0.037) were significant predictors for progression to the chronic recurrent phase. ADA significantly reduced anterior chamber inflammatory cells (P = 0.000) and vitreous cavity inflammatory cells (P = 0.001) in the chronic-recurrent group, and markedly decreased the recurrence rate in VKH patients (P = 0.009).
CONCLUSION
In comparison to acute-resolved patients, chronic-recurrent patients exhibited poorer initial BCVA and a significantly increased incidence of "sunset glow fundus." Older age at onset and the occurrence of "sunset glow fundus" at diagnosis are crucial predictive factors for VKH patients progressing to the chronic recurrent phase. ADA effectively alleviates refractory VKH disease and is generally well-tolerated.

Review
There has been a call to action to enhance representation of non-white individuals in dermatology clinical trials. Investigations in differential response to treatment across populations are limited, particularly in conditions of commonality, impact, distinct presentation, and diagnosis in non-white participants, such as atopic dermatitis and psoriasis. This systematic review summarized and identified if biologic treatment outcomes in moderate-to-severe atopic dermatitis and psoriasis varied in skin of colour (SOC) participants in phase 3 trials. MEDLINE, COCHRANE, and EMBASE databases were used to conduct the search following PROSPERO registration. Following screening of 3209 articles, 11 studies were collected with 1781 SOC participants with a mean age of 40.99 ± 6.3 years (range: 30.6-51.6 years). Male participants accounted for 76.9% (n = 1370/1781) of the sample, and Chinese, Japanese, Taiwanese, and Korean participants accounted for 64.3%, 24.2%, 4.5%, and 3.4% of participants, respectively. Participants with atopic dermatitis were treated with dupilumab (n = 216/388) and participants with psoriasis were treated with adalimumab (n = 313/1393), bimekizumab (n = 62/1393), ixekizumab (n = 13/1393), secukinumab (n = 117/1393), and ustekinumab (n = 289/1393). No significant SOC population-based outcomes were found across treatment groups. However, differences in baseline characteristics or comorbidities were found, suggesting race or ethnic background should be considered when treatment is prescribed in psoriasis or atopic dermatitis. Although no significant SOC participant differential response to treatment were found, large-scale randomized controlled trials investigating comparable treatment outcomes and stratifying results by SOC population in atopic dermatitis and psoriasis are warranted to confirm these findings.

INTRODUCTION
Acquired Hemophilia A (AHA) is a rare autoimmune disorder characterized by the emergence of inhibitors that specifically target coagulation Factor VIII, frequently resulting in severe bleeding episodes.
METHODS
We conducted a retrospective analysis of the medical records of a 68-year-old male patient who presented with adalimumab-induced AHA.
RESULTS
The patient received adalimumab, a tumor necrosis factor inhibitor antibody, as part of his treatment for rheumatoid arthritis. The patient's clinical journey, characterized by intense bleeding and coagulopathy, was effectively managed with the application of recombinant Factor VIIa (rFVIIa) and the CyDRi protocol.
DISCUSSION
The case emphasizes the importance of prompt coagulation assessment in patients with bleeding symptoms receiving disease-modifying therapy for rheumatoid arthritis that includes adalimumab therapy, considering the rare yet life-threatening nature of AHA. Additionally, this report provides an extensive review of the existing literature on drug-induced AHA, with a special emphasis on cases linked to immunomodulatory medications. Through this two-pronged approach, our report aims to enhance understanding and awareness of this severe complication among healthcare providers, promoting timely diagnosis and intervention.

Outcomes after anti-tumour necrosis factor originator to biosimilar switching in children and young people with juvenile idiopathic arthritis in the UK: a national cohort study.
BACKGROUND
For cost-saving purposes, children and young people with juvenile idiopathic arthritis (JIA) are being switched (for non-medical reasons) from biological originators to biosimilars. Here, we aimed to investigate those who switched from an anti-tumour necrosis factor (TNF) originator to a biosimilar, regarding drug survival and disease activity, compared with a matched cohort who continued the originator.
METHODS
This analysis included all patients in the UK JIA Biologics Register switching directly from an anti-TNF originator to a biosimilar of the same product. All patients were matched (age, sex, disease duration, calendar year of when patients started originator therapy, line of therapy, and International League of Associations for Rheumatology [ILAR] category) to patients continuing the originator. For those matched successfully, a Cox proportional hazard model assessed whether drug persistence differed between those who switched compared with those who continued the originator. Overall change in the 71-joint juvenile arthritis disease activity score and the proportion of patients with a clinically important worsening score (by ≥1·7 units) after 6 months was compared between cohorts. This analysis was designed to address a priority research area set by our patient partners.
FINDINGS
There were 224 children and young people with non-systemic JIA (139 [62%] were female, and 85 [38%] were male) identified as switching from a biological originator to a biosimilar of the same product from Jan 1, 2017, to July 7, 2023. 143 (64%) patients were originally on adalimumab, 56 (25%) on etanercept, and 25 (11%) on infliximab. Of these, 164 patients were matched successfully to those continuing the originator. There was no evidence that patients switching were more likely to stop treatment compared with those continuing the originator, with a hazard ratio of 1·46 (95% CI 0·93-2·30). Of the 51 patients in the biosimilar group who stopped treatment, 18 (35%) switched back to the originator (14 in the first year), 28 (55%) started a different biological drug, and five (10%) discontinued all treatment by the last follow-up. Of the 87 matched patients with available disease activity, there was no evidence that JADAS-71 worsened more after 6 months, with an odds ratio of 0·71 (95% CI 0·34-1·51; p=0·38).
INTERPRETATION
In this matched comparative effectiveness analysis, children and young people with JIA switched from originators to biosimilars. Disease activity was similar between patients switching compared with those continuing the originator. Three quarters of patients were still receiving their biosimilar after 1 year, with switching back to originator uncommon, at only 9% after 1 year, suggesting good tolerability of non-medical switching in this patient population. This information is reassuring to clinicians and patients regarding the effect of non-medical biological switching.

PloS One 2024To evaluate the impact of the entry of biosimilars on the pricing of eight biologic products in 57 countries and regions.
OBJECTIVE
To evaluate the impact of the entry of biosimilars on the pricing of eight biologic products in 57 countries and regions.
METHODS
We utilized an interrupted time series design and IQVIA MIDAS® data to analyze the annual sales data of eight biologic products (adalimumab, bevacizumab, epoetin, etanercept, filgrastim, infliximab, pegfilgrastim, and trastuzumab) across 57 countries and regions from January 1, 2012, to December 31, 2019. We examined the immediate and long-term changes in biologics ex-manufacturer pricing following the entry of biosimilars to the market.
RESULTS
Following the entry of biosimilars, the average price per dose of biologic product was immediately reduced by $438 for trastuzumab, $112 for infliximab, and $110 for bevacizumab. The persistent effect of biosimilars' market entry led to further reductions in price per dose every year: by $49 for adalimumab, $290 for filgrastim, $21 for infliximab, and $189 for trastuzumab. Similarly, we analyzed the impact of biosimilars on four biologics' prices in the US, where the prices of three biologics significantly decreased every year, with filgrastim, pegfilgrastim, and infliximab decreasing by $955, $753, and $104, respectively.
CONCLUSIONS
The introduction of biosimilars has significantly reduced the prices of biologics both globally and in the US. These findings not only demonstrate the economic benefits of increasing biosimilar utilization, but also emphasize the importance of biosimilars in controlling healthcare costs. Policies should aim to expand the availability of biosimilars to counteract the exponential growth of medical spending caused by the use of biologics.

In recent years, with the increased usage of tumour necrosis factor (TNF) inhibitors, more side effects have been revealed. Paradoxical psoriasis, including psoriasis vulgaris, palmoplantar pustulosis, scalp psoriasis and their combinations, is a common adverse effect. However, erythrodermic psoriasis associated with alopecia due to anti-TNF-α is rarely reported in the literature. We report a 44-year-old woman who developed erythrodermic psoriasis associated with diffuse alopecia during her treatment with adalimumab for palmoplantar pustulosis.

Review
Ulcerative colitis (UC) is an inflammatory disorder affecting the colon, and typically, during the disease course, the condition may exacerbate, relapse, and remit. One of the most successful lines for inducing and maintaining clinical remission in subjects with UC is biological therapy with anti-tumor necrosis factor α (anti-TNF) agents, including adalimumab (ADA) and infliximab (IFX). This meta-analysis is an attempt to obtain complementary information driven by real-world experience (RWE) concerning the efficacy and safety of two of the most popular anti-TNFs in treating UC. This is a systematic review and meta-analysis of RWE studies comparing ADA and IFX as naïve anti-TNF agents for the treatment of subjects with UC. Studies were obtained by searching Scopus, Google Scholar, the Cochrane Central Register of Controlled Trials, Embase, and the PubMed Central databases. Patients treated with IFX showed significantly higher induction responses. No statistically significant difference was found in the comparison of response in the maintenance treatment period. Higher overall adverse events were related to IFX treatment, with serious adverse events that were nonsignificantly higher in the ADA-treated group. In conclusion, IFX demonstrated significantly higher induction responses compared to ADA in patients with moderate-to-severe UC. IFX was associated with higher overall adverse events, whereas serious adverse events were non-significantly higher in the ADA-treated group. IFX may be favored as a first-line agent for its induction efficacy, and the choice between IFX and ADA should be individualized based on comprehensive clinical evaluation.
