Treatment of hemorrhagic hepatic cysts with omentalization in a serval.

A 2 year old, spayed female African serval was evaluated for a history of abdominal distention. Physical examination findings were consistent with cranial abdominal masses and anemia. Abdominal imaging revealed soft tissue opacity masses in the cranial abdomen and hypoechoic cysts arising from the liver parenchyma. Conservative management failed to improve clinical signs, and a midline exploratory laparotomy was performed. Three large hemorrhagic cysts were visualized occupying a significant amount of the liver parenchyma. The cysts were drained, omentalized and partially closed with a surgical stapler and suture. Histopatological evaluation of the resected tissue was consistent with a chronic hepatic hematoma. The patient recovered well and was discharged 3 days postoperatively. Two years later, the patient was readmitted with the same clinical signs and large multiple hepatic cysts involving most of the liver lobes. These were surgically omentalized similarly to the previous surgery and the patient recovered well postoperatively. Two years later, return to normal life and no recurrence of the cysts was reported

Long-term efficacy and safety of brodalumab in the treatment of psoriasis : 120-week results from the randomized, double-blind, placebo- and active comparator-controlled phase 3 AMAGINE-2 trial

Randomized controlled trials have shown the efficacy and safety of brodalumab in patients with moderate to severe plaque psoriasis. To evaluate the efficacy and safety of brodalumab through 120 weeks of treatment in the AMAGINE-2 trial. Patients received ustekinumab through week 52 followed by brodalumab 210 mg every 2 weeks, continuous brodalumab 210 mg every 2 weeks, or any dose of brodalumab. Efficacy data were reported through 120 weeks by using observed data, last observation carried forward, and nonresponder imputation analyses. Of patients who received brodalumab 210 mg every 2 weeks, 84.4%, 75.6%, and 61.1% achieved 75%, 90%, and 100% improvement from baseline in Psoriasis Area and Severity Index at 120 weeks (observed data analysis), respectively. Patients who received brodalumab 210 mg every 2 weeks after receiving ustekinumab through 52 weeks achieved a similar skin clearance response as patients who received continuous brodalumab 210 mg every 2 weeks. Safety through 120 weeks was comparable to that of the blinded study periods. A large number of discontinuations toward the end of the study (31% in the final 6 months) were due to early termination and led to differences between observed data and nonresponder imputation results. Brodalumab is well tolerated and showed robust efficacy for more than 2 years

Efficacy of a fixed combination of calcipotriol/betamethasone dipropionate topical gel in adult patients with mild to moderate psoriasis: blinded interim analysis of a phase IV, multicenter, randomized, controlled, prospective study

Background: Psoriasis is a common, chronic, inflammatory skin disease with the majority of individuals having limited disease, treated with topical medication. However, special attributes of topical treatments like galenic/cosmetic properties or an inconvenient treatment schedule may result in low preference for topical treatments. Hence, there is strong medical need for a topical medication, which is highly efficacious, easy-to-use and preferred by both physicians and patients. Objective: Blinded interim analysis with the purpose to assess efficacy of (both from the physician's and patient's perspective) and the patients' preference with a highly efficacious and easy-to-use fixed combination of calcipotriol/betamethasone dipropionate topical gel after 8 weeks of once daily treatment in a large patient population. Methods: In this phase IV, international, multicentre, randomized, controlled, prospective, parallel group study, adult patients with active, mild to moderate psoriasis despite previous topical psoriasis treatment, i.e. unsuccessful in the 8 weeks preceding study participation, are followed over 64 weeks. During the first 8 weeks the patients apply their medication once a day followed by a 56-weeks maintenance period according to SmPC. Blinded interim analysis of all patients included demographics, Physician's Global Assessment, the novel Patient's self Global Assessment (PsGA) and Patient Preference Questionnaire (PPQ). Results: 1795 patients were analysed. At week 8, 36.5% of the physicians rated the patients' psoriasis as clear/almost clear. Similarly, based on the patients' self-assessment, 34.2% had a clear/almost clear score of PsGA in week 8. Analysis of the PPQ showed that the vast majority of the patients judged their 8-week treatment to be preferable compared with their previous treatments. Conclusion: Results of this blinded interim analysis indicate that the fixed combination of calcipotriol/betamethasone dipropionate gel is highly efficacious and preferred by the majority of analysed patients

Clinical similarity of biosimilar ABP 501 to adalimumab in the treatment of patients with moderate to severe plaque psoriasis: A randomized, double-blind, multicenter, phase III study

Background ABP 501 is a biosimilar of adalimumab. Objective We sought to compare the efficacy and safety of ABP 501 with adalimumab. Methods This 52-week, double-blind study randomized patients with moderate to severe psoriasis to ABP 501 or adalimumab. At week 16, those with 50% or more improvement in Psoriasis Area and Severity Index score from baseline on ABP 501 continued the same treatment, whereas adalimumab-treated patients were rerandomized to adalimumab or ABP 501. Clinical similarity in Psoriasis Area and Severity Index percent improvement from baseline to week 16 (primary end point) was established if the point estimate of treatment difference and its 2-sided 95% confidence interval between groups was within equivalence margin of ±15. Patients, including those undergoing a single transition at week 16, were evaluated for safety and immunogenicity. Results Psoriasis Area and Severity Index percent improvement at week 16 was 80.9 for ABP 501 and 83.1 for adalimumab (least-square mean difference −2.18 [95% confidence interval −7.39 to 3.02]). Adverse events (67.2% [117/174] vs 63.6% [110/173]) and antidrug antibody incidence (55.2% [96/174] vs 63.6% [110/173]) for ABP 501 vs adalimumab were similar. Safety, including immunogenicity, was similar among groups after single transition (week 20). Limitations The 52-week data are not reported here. Conclusions ABP 501 was shown to be clinically similar to adalimumab. Safety and immunogenicity were not impacted immediately after single transition (adalimumab to ABP 501)

Rapid and sustained improvements in Generalized Pustular Psoriasis Physician Global Assessment scores with spesolimab for treatment of generalized pustular psoriasis flares in the randomized, placebo-controlled Effisayil 1 study

BACKGROUND: Effisayil 1 was a randomized, placebo-controlled study of spesolimab, which is an anti-IL-36 receptor antibody, in patients presenting with a generalized pustular psoriasis flare. OBJECTIVE: To assess the effects of spesolimab over the 12-week study. METHODS: The primary endpoint of the study was Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 at week 1. Patients (N = 53) were randomized (2:1) to receive a single intravenous dose of 900 mg spesolimab or placebo on day 1. Patients could receive open-label spesolimab for persistent flare symptoms on day 8. RESULTS: Most patients receiving spesolimab achieved a GPPGA pustulation subscore of 0 (60.0%) and GPPGA total score of 0 or 1 (60.0%) by week 12. In patients randomized to placebo who received open-label spesolimab on day 8, the proportion with GPPGA pustulation subscore of 0 increased from 5.6% at day 8 to 83.3% at week 2. No factors predictive of spesolimab response were identified in patient demographics or clinical characteristics. LIMITATIONS: The effect of initial randomization was not determined conventionally beyond week 1 due to patients receiving open-label spesolimab. CONCLUSION: Rapid control of generalized pustular psoriasis flare symptoms with spesolimab was sustained over 12 weeks, further supporting its potential use as a therapeutic option for patients

Generalized pustular psoriasis is a disease distinct from psoriasis vulgaris: evidence and expert opinion

Introduction: Generalized pustular psoriasis (GPP) is a rare, severe, clinically heterogeneous disease characterized by flares of widespread, noninfectious, macroscopically visible pustules that occur with or without systemic inflammation, and are associated with significant morbidity and mortality. Historically, GPP has been classified as a variant of psoriasis vulgaris (PV, or plaque psoriasis); however, accumulating evidence indicates that these are distinct conditions, requiring different treatment approaches. Areas covered: In this perspective article we review evidence that supports the classification of GPP as distinct from PV. Expert opinion: The histopathologic and clinical appearance of GPP is distinct from that of PV and fundamental differences exist between the two conditions in terms of genetic causes and expression-related mechanisms of disease development. GPP results from dysregulation of the innate immune system, with disruption of the interleukin (IL)-36 inflammatory pathway, induction of inflammatory keratinocyte responses, and recruitment of neutrophils. PV is driven by the adaptive immune system, with a key role played by IL-17. Considering GPP as a separate disease will enable greater focus on its specific pathogenesis and the needs of patients. Many treatments for PV have insufficient efficacy in GPP and a therapeutic approach developed specifically for GPP might lead to better patient outcomes. Plain Language Summary: Generalized pustular psoriasis (GPP) is a rare disease. During episodes of worsening disease, the immune system attacks the skin. This causes large areas of skin to become red and painful, pus-filled blisters suddenly form. Some people with GPP have a history of another, more common, skin condition called psoriasis vulgaris (PV). People with PV develop patches of scaly, itchy skin. In the past, GPP was classed as a type of PV and treated with the same medicines. However, these medicines do not work well in GPP. Researchers now understand more about what causes GPP and how it differs from PV. GPP can cause medical problems throughout the body, leading to life-threatening complications. This means that people with GPP often need urgent medical treatment in hospitals. People with PV are mostly treated outside of hospitals. Any other medical problems are not usually due to PV itself. Researchers have found several genes that are altered in people with GPP and PV, and they differ between the two diseases. For example, changes in a gene called IL36RN are common in GPP but are not seen in PV. The skin of people with these two diseases also looks different under a microscope. Knowing more about GPP and how it differs from PV will help people with GPP to be diagnosed more quickly. It will also help researchers to develop new medicines specifically for GPP, so people can receive better treatment in the future

Design of Effisayil™ 2: A randomized, double-blind, placebo-controlled study of spesolimab in preventing flares in patients with generalized pustular psoriasis

INTRODUCTION: Generalized pustular psoriasis (GPP) is a rare autoinflammatory skin disease characterized by flares of widespread erythema with sterile pustules, and can be relapsing with recurrent flares, or persistent with intermittent flares. Spesolimab, a humanized anti-interleukin-36 (IL-36) receptor monoclonal antibody, targets the key IL-36 pathogenetic pathway in GPP. A previous study showed that spesolimab treatment led to rapid pustular and skin clearance in patients with GPP flares, which was sustained for up to 12 weeks. This study investigates the long-term effects of spesolimab on GPP flares, for which no specific treatments are currently available. The Effisayil™ 2 study will assess whether maintenance treatment with subcutaneous spesolimab prevents the occurrence of GPP flares and determine the optimal dosing regimen to achieve this aim. METHODS: Patients will have a documented history of GPP with a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) score of 0 or 1 (clear or almost clear) at screening and randomization. Patients will be randomized 1:1:1:1 to three groups receiving a 600-mg subcutaneous loading dose of spesolimab followed by a 300-mg maintenance dose administered every 4 or 12 weeks, or a 300-mg loading dose followed by a 150-mg maintenance dose administered every 12 weeks, and one group receiving placebo, for 48 weeks. The primary endpoint is time to first GPP flare. If a patient experiences a GPP flare during the randomized maintenance treatment period, an open-label intravenous dose of 900-mg spesolimab will be administered, with an option for a second intravenous dose after 1 week. CONCLUSIONS: Effisayil™ 2 is the first placebo-controlled study in patients with GPP to investigate whether maintenance treatment with spesolimab can prevent flares and provide sustained disease control. This study will provide valuable insights on the long-term management of patients with this potentially life-threatening skin disease. TRIAL REGISTRATION NUMBER: NCT04399837

Long-Term Safety of Risankizumab in Patients with Psoriatic Disease: A Comprehensive Analysis from Clinical Trials

Introduction: Risankizumab has demonstrated a favourable safety profile in patients with psoriatic disease (moderate-to-severe psoriasis [PsO] and psoriatic arthritis [PsA]). We evaluated the long-term safety of risankizumab in psoriatic disease. Methods: Long-term safety was evaluated by analysing data from 20 (phase 1–4) clinical trials for plaque PsO and four (phase 2–3) trials for PsA. Treatment-emergent adverse events (TEAEs) and AEs in areas of special interest were reported among patients receiving ≥ 1 dose of risankizumab. Exposure-adjusted event rates were presented as events (E) per 100 patient-years (PY). Results: The long-term safety data analyses included 3658 patients with PsO (13,329.3 PY) and 1542 patients with PsA (3803.0 PY). The median (range) treatment duration for patients with PsO and PsA was 4.1 (0.2–8.8) years and 2.8 (0.2–4.0) years, respectively. In the PsO population, rates of TEAEs, serious AEs and AEs leading to discontinuation were 145.5 E/100 PY, 7.4 E/100 PY and 1.9 E/100 PY, respectively; in the PsA population, these rates were 142.6 E/100 PY, 8.6 E/100 PY, and 1.8 E/100 PY, respectively. The rates of serious infections (excluding COVID-19-related infections) in the PsO and PsA populations were 1.2 and 1.4 E/100 PY, respectively. The rates of opportunistic infections (excluding tuberculosis and herpes zoster) were low (< 0.1 E/100 PY) in both populations. The rates of both nonmelanoma skin cancer (NMSC) and malignant tumours excluding NMSC were 0.6 and 0.5 E/100 PY in PsO and PsA, respectively, which are within the benchmarks of prior epidemiological studies. Adjudicated major cardiovascular event rates were 0.5 E/100 PY in PsO and 0.3 E/100 PY in PsA, which are within the epidemiologic reference benchmarks for both indications. No additional safety concerns were identified with this long-term exposure. Conclusions: The results support the favourable safety profile of risankizumab for long-term treatment of psoriatic disease with no new safety concerns and similar safety profiles among both PsO and PsA populations
