The state of food systems worldwide in the countdown to 2030

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

Super-Response to Guselkumab Treatment in Patients With Moderate-to-Severe Psoriasis: Age, Body Weight, Baseline Psoriasis Area and Severity Index, and Baseline Investigator's Global Assessment Scores Predict Complete Skin Clearance

BACKGROUND

Psoriasis is a chronic immune-mediated inflammatory skin disease that often leads to a diminished quality of life. Goals of treating patients with psoriasis have shifted with more focus on achieving near or complete clearance of the skin. Guselkumab, a fully human monoclonal antibody targeting interleukin-23, is effective in treating moderate-to-severe psoriasis.

OBJECTIVE

To describe the baseline characteristics of patients with moderate-to-severe psoriasis achieving super-response (Psoriasis Area and Severity Index [PASI] 100 response at Weeks 20 and 28) after commencing guselkumab treatment.

METHODS

Pooled data from VOYAGE-1 and VOYAGE-2 studies identified super-response; baseline demographic, disease, and pharmacokinetic characteristics were compared with non-super-response. A stepwise logistic regression analysis identified which factors were potentially predictive of super-response status, with significance level of 0.1.

RESULTS

A subset of patients randomized to guselkumab comprised this post hoc analysis (n=664); 271 patients achieved super-response vs 393 with non-super-response. Patient age at study entry and baseline body weight (≤90 kg vs >90 kg), PASI, and Investigator's Global Assessment (IGA) score were significant predictors of super-response status, with odds ratios (95% confidence intervals) of 0.98 (0.967-0.993; p=0.003), 1.42 (1.026-1.977; p=0.034), 0.97 (0.955-0.993; p=0.007), and 0.66 (0.433-0.997; p=0.048), respectively. More patients with super-response achieved an early response: Week 2 PASI 75 (5.5% vs 1.8%) and Week 8 PASI 100 (22.5% vs 3.3%) vs non-super-response. Median serum guselkumab concentrations through Week 28 were slightly greater in patients with super-response vs non-super-response.

CONCLUSION

Guselkumab was more likely to achieve early clinical responses (complete skin clearance) in younger patients, less obese patients, and patients with less severe psoriasis.

AB0892 Targeted Safety Analyses of Guselkumab: Long-Term Results from Randomized Clinical Trials in Patients with Active Psoriatic Arthritis and Moderate to Severe Psoriasis

Background

Guselkumab (GUS) demonstrated efficacy and a favorable safety profile in active PsA in the Phase (Ph) 21 and Ph3 DISCOVER-1&2 trials2,3 and in moderate-to-severe plaque psoriasis (PsO) in the Ph3 VOYAGE-1&2 trials.4,5

Objectives

To assess long-term safety of GUS across PsA/PsO trials.

Methods

Using pooled safety data through 2 years (yrs) from PsA trials (N=1229; GUS 100 mg every 4/8 weeks [Q4W/Q8W])1-3 and through 5 yrs from PsO trials (N=1721; GUS 100 mg Q8W),4,5 incidences of serious adverse events (SAEs); gastrointestinal (GI)-related SAEs and other targeted AEs; including candidiasis, uveitis, and opportunistic infections (OIs) were evaluated. Incidence rates (IRs) were calculated as the number of events per 100 pt-yrs (PY) of follow-up with 95% CI. Patients (pts) with an IBD history were not excluded in PsA/PsO trials. Max exposure duration was W100 for PsA trials and W252 for PsO trials.

Results

The PsA and PsO populations had comparable mean age and BMI. IRs of SAEs and GI-related SAEs were generally similar between GUS- and PBO-treated pts during PBO-controlled periods, and between PsA pts receiving GUS Q4W/Q8W for up to 2 yrs and PsO pts receiving GUS Q8W for up to 5 yrs (Table 1). IRs of other targeted AEs of interest were low. OIs did not occur in PsO pts and were infrequent in PsA pts (Table 1). Candidal infections were infrequent and non-serious. Iridocyclitis was reported in 1 PBO- and 1 GUS Q8W-treated PsA pt. No exacerbations or new onset of IBD or active tuberculosis was reported in GUS-treated PsA/PsO pts.

AB1473 EFFICACY RESPONSES ACROSS DISEASE SEVERITY AND TREATMENT HISTORY SUBGROUPS OF PATIENTS WITH MODERATE TO SEVERE PLAQUE PSORIASIS TREATED WITH GUSELKUMAB: POOLED RESULTS FROM VOYAGE-1 AND VOYAGE-2 THROUGH 5 YEARS

Background

The VOYAGE-1 and VOYAGE-2 phase 3 studies evaluated efficacy and safety of guselkumab (GUS) in patients with moderate-to-severe plaque psoriasis.

Objectives

To assess the five-year efficacy of GUS by baseline disease characteristics and treatment history.

Methods

This study evaluated 1829 patients randomized to GUS, placebo (PBO)→GUS, and adalimumab (ADA) →GUS from the VOYAGE-1 and VOYAGE-2 trials. All patients received open-label GUS 100 mg every 8 weeks (Q8W) during Week (W) 52 to W252 in VOYAGE-1 and during W76 to W252 in VOYAGE-2. The proportions of combined GUS patients (including PBO→GUS and ADA→GUS) achieving Investigator’s Global Assessment of cleared or minimal (IGA-0/1) and Psoriasis Area and Severity Index (PASI) 90 response were evaluated from W100 to W252 by baseline PASI (<20/≥20) and IGA (<4/=4) scores, body surface area (BSA; <20%/≥20%), and prior psoriasis treatments. Analysis was performed using observed data after applying treatment failure rules.

Results

At W252, proportions of combined GUS patients achieving IGA 0/1 or PASI 90, respectively, were comparable or numerically greater for patients with baseline PASI < 20 (85.4%; 81.1%) vs PASI ≥ 20 (81.4%; 83.8%); IGA < 4 (85.1%; 82.7%) vs IGA = 4 (78.9%; 81.1%); BSA < 20% (85.1%; 82.7%) vs BSA ≥ 20% (82.6%; 82.0%); no prior phototherapy (83.3%; 84.0%) vs prior phototherapy (83.8%; 81.1%); no prior non-biologic systemic therapy (84.5%; 83.0%) vs prior non-biologic systemic therapy (83.2%; 82.0%); and no prior biologics (85.3%; 83.8%) vs prior biologics (76.7%; 76.3%). This trend was consistent at each timepoint evaluated from W100 to W252.

Conclusion

This analysis demonstrated that the high degree of efficacy of GUS treatment is durable through 5 years among broad subpopulations of patients with varying disease severity characteristics and previous psoriasis treatments.

Myocardial fibrosis predicts ventricular arrhythmias and sudden death after cardiac electronic device implantation

Funding Acknowledgements

Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Unrestricted educational grants

Background

Increasing evidence supports a link between myocardial fibrosis (MF) and ventricular arrhythmias. We sought to determine whether presence of MF on visual assessment (MFVA) and gray zone fibrosis (GZF) mass predicts SCD and ventricular fibrillation / sustained ventricular tachycardia after cardiac implantable electronic device (CIED) implantation.

Methods

In this prospective study, total fibrosis and GZF mass, quantified using cardiovascular magnetic resonance, was assessed in relation to the primary endpoint of sudden cardiac death (SCD) and the secondary, arrhythmic endpoint of SCD or ventricular arrhythmias after CIED implantation.

Results

Among 700 patients (age 68.0 ± 12.0yrs [mean ± SD]), 27 (3.85%) experienced a SCD and 121 (17.3%) met the arrhythmic endpoint over 6.93 yrs (median; interquartile range 5.82-9.32). MFVA predicted SCD (hazard ratio [HR]: HR:26.3 [95% confidence interval [CI] 3.70-3337]; negative predictive value: 100%). In competing risks analyses, MFVA also predicted the arrhythmic endpoint (subdistribution [sHR]: 19.9 [95% CI 6.40-61.9]; negative predictive value:98.6%). Compared with no MFVA, a GZF mass measured with the 5SD method (GZF5SD) &gt; 17 g was associated with highest risk of SCD (HR: 44.6;95% CI 6.12-5685) and the arrhythmic endpoint (sHR: 30.3 [95% CI 9.60-95.8]). Adding GZF5SD mass to MFVA led to reclassification of 39% for SCD and 50.2% for the arrhythmic endpoint. In contrast, LVEF did not predict either endpoint.

Conclusions

In CIED recipients, MFVA excluded patients at risk of SCD and virtually excluded ventricular arrhythmias. Quantified GZF5SD mass added predictive value in relation to SCD and the arrhythmic endpoint.

Five-year maintenance of clinical response and health-related quality of life improvements in patients with moderate-to-severe psoriasis treated with guselkumab: results from VOYAGE 1 and VOYAGE 2

BACKGROUND

Psoriasis is a chronic disease requiring long-term therapy.

OBJECTIVES

Physician- and patient-reported outcomes were evaluated through week 252 in VOYAGE 1 and VOYAGE 2.

METHODS

In total, 1829 patients were randomized at baseline to receive guselkumab 100 mg every 8 weeks, placebo or adalimumab. Patients receiving placebo crossed over to guselkumab at week 16. Patients receiving adalimumab crossed over to guselkumab at week 52 in VOYAGE 1, and randomized withdrawal and retreatment occurred at weeks 28-76 in VOYAGE 2; all patients then received open-label guselkumab through week 252. Efficacy and health-related quality of life (HRQoL) endpoints were analysed through week 252. Safety was monitored through week 264.

RESULTS

The proportions of patients in the guselkumab group who achieved clinical responses at week 252 in VOYAGE 1 and VOYAGE 2, respectively, were 84·1% and 82·0% [≥ 90% improvement in Psoriasis Area and Severity Index (PASI)]; 82·4% and 85·0% [Investigator's Global Assessment (IGA) 0 or 1]; 52·7% and 53·0% (100% improvement in PASI) and 54·7% and 55·5% (IGA 0). HRQoL endpoints were achieved as follows: 72·7% and 71·1% of patients (Dermatology Life Quality Index 0 or 1: no effect on patient's life); 42·4% and 42·0% [Psoriasis Symptoms and Signs Diary (PSSD) symptom score = 0] and 33·0% and 31·0% (PSSD sign score = 0). As measured in VOYAGE 2 only, approximately 45% of patients achieved ≥ 5-point reduction in Short Form-36 physical and mental component scores, and 80% reported no anxiety or depression (Hospital Anxiety and Depression Scale scores < 8). Similar findings were reported for adalimumab crossovers. These effects were maintained from week 52 in VOYAGE 1 and week 100 in VOYAGE 2. No new safety signals were identified.

CONCLUSIONS

Guselkumab maintains high levels of clinical response and improvement in patient-reported outcomes through 5 years in patients with moderate-to-severe psoriasis.

POS1031 LOW INCIDENCE OF GASTROINTESTINAL-RELATED AND OVERALL SERIOUS ADVERSE EVENTS AMONG GUSELKUMAB-TREATED PATIENTS: POOLED ANALYSES OF VOYAGE 1 & 2 AND DISCOVER 1 & 2 THROUGH 1-YEAR

Background:

Guselkumab (GUS), a human monoclonal antibody that specifically binds to the p19-subunit of interleukin (IL)-23, demonstrated efficacy in the Phase 3 VOYAGE 1&2 trials of patients (pts) with moderate to severe plaque psoriasis (PsO)1,2 and in the DISCOVER 1&2 trials of pts with active psoriatic arthritis (PsA).3,4 IL-17 inhibitors used to treat PsO and PsA have been associated with exacerbation or new onset of inflammatory bowel disease (IBD) (e.g., Crohn’s disease or ulcerative colitis).5

Objectives:

Evaluate the incidence of gastrointestinal (GI)-related and overall serious adverse events (SAEs) from pooled safety data through 1-year of GUS 100 mg treatment from the VOYAGE 1&2 and DISCOVER 1&2 trials.

Methods:

Using pooled safety data from the VOYAGE 1&2 PsO trials and DISCOVER 1&2 PsA trials, SAEs related to GI disorders were identified using the Medical Dictionary for Regulatory Activities (MedDRA) system-organ class “GI disorders”. Pts with a previous history of IBD were not excluded in these trials; medical history of IBD was collected at baseline in DISCOVER 1&2. Rates of overall SAEs and GI-related SAEs were calculated as the number of SAEs per 100 pt-years (PY) of follow-up (95% confidence intervals). Data are presented for the placebo (PBO)-controlled period (Weeks 0-16 for VOYAGE 1&2; Weeks 0-24 for DISCOVER 1&2) and through 1-year (defined as through Week 48 for VOYAGE 1&2; through Week 60 for DISCOVER 1, and through Week 52 for DISCOVER 2). Events of uveitis and opportunistic infections were also analyzed.

Results:

Through the PBO-controlled period, the overall rates of GI-related SAEs per 100 PY for pooled VOYAGE 1&2 were: PBO 0.78 (0.02, 4.34), GUS q8w 0; and for pooled DISCOVER 1&2: PBO 0.58 (0.01, 3.23), GUS q8w 0.58 (0.01, 3.21), GUS q4w 0. The GI-related SAEs included: gastrointestinal hemorrhage (PBO; n=1) for pooled VOYAGE 1&2; and inflammatory bowel disease (PBO; n=1) and mechanical ileus (GUS q8w; n=1) for pooled DISCOVER 1&2. Through 1-year, the overall rates of GI-related SAEs for pooled VOYAGE 1&2 were: Combined GUS group (GUS q8w and PBO→GUS groups) 0.51 (0.17, 1.20); and for pooled DISCOVER 1&2: GUS q8w 0.52 (0.06, 1.88), GUS q4w 0, Combined GUS group (GUS q8w, GUS q4w, and PBO→GUS groups) 0.21 (0.02, 0.74). The GI-related SAEs in the Combined GUS group for pooled VOYAGE 1&2 included: gastritis, hemorrhoids, inguinal hernia, pancreatitis, and umbilical hernia (0.10/100PY [0.00, 0.57]; n=1 for each); and in the Combined GUS group for pooled DISCOVER 1&2: mechanical ileus and pancreatitis chronic (0.10/100PY [0.00, 0.57]; n=1 for each). Overall, no cases of exacerbation or new onset of IBD were reported in GUS-treated pts, including 2 pts with a prior history of IBD in DISCOVER 1&2 (total PY of follow-up for the Combined GUS groups in VOYAGE and DISCOVER were 974 and 973, respectively). Through the PBO-controlled period, rates of overall SAEs for GUS-treated pts were comparable to PBO-pts and SAE rates remained low through 1-year of follow-up in the VOYAGE 1&2 and DISCOVER 1&2 trials. There were no reported cases of uveitis, opportunistic infections, or tuberculosis in GUS-treated pts through 1-year.

Conclusion:

Through 1-year of follow-up with GUS treatment in pooled VOYAGE 1&2 and DISCOVER 1&2, GI-related SAE rates were low. There were no reported cases of uveitis, opportunistic infections, or new onset/exacerbation of IBD in GUS-treated pts. No new safety concerns were identified through 1-year.

Five-year efficacy and safety of tildrakizumab in patients with moderate-to-severe psoriasis who respond at week 28: pooled analyses of two randomized phase III clinical trials (reSURFACE 1 and reSURFACE 2)

BACKGROUND

The phase III reSURFACE 1 and reSURFACE 2 (NCT01722331/NCT01729754) trials of the anti-interleukin-23p19 monoclonal antibody tildrakizumab (TIL) for psoriasis treatment are complete.

OBJECTIVES

We present 5-year pooled data from reSURFACE 1 and reSURFACE 2.

METHODS

reSURFACE 1 and reSURFACE 2 were double-blind, randomized, controlled studies with optional long-term extensions. Adults with moderate-to-severe chronic plaque psoriasis were randomized 2 : 2 : 1 to TIL 100 mg (TIL 100) or 200 mg (TIL 200) or placebo at weeks 0 and 4, and every 12 weeks thereafter [reSURFACE 2 included an etanercept (ETN) arm]. Efficacy outcomes included proportions of patients achieving absolute and relative improvement from baseline Psoriasis Area and Severity Index (PASI) score through week 244 in TIL responders (≥ 75% improvement from baseline PASI; PASI 75 response) continuously receiving the same dose and ETN partial responders and nonresponders (PASI < 75 response) switched to TIL 200 at week 28. Safety was assessed from adverse events (AEs) in all patients as treated.

RESULTS

Efficacy analyses included 329 and 227 week 28 responders to TIL 100 and TIL 200, respectively, and 121 ETN partial responders/nonresponders switched to TIL 200 at week 28. Of TIL 100 or TIL 200 responders and ETN partial responders/nonresponders entering the extensions, 235/302, 176/213 and 85/107, respectively, were evaluated at week 244, and 88·7%, 92·5% and 81·3%, respectively, achieved PASI 75 response. Exposure-adjusted rates of serious AEs were 6·3 and 6·0 patients with events per 100 patient-years of TIL 100 and TIL 200, respectively.

CONCLUSIONS

TIL treatment provided sustained disease control over 5 years in week 28 TIL responders and ETN partial responders/nonresponders, with a reassuring safety profile.

Efficacy and Safety of Bimekizumab in Patients with Moderate to Severe Plaque Psoriasis: Results from BE READY, a 56-Week Phase 3, Randomized, Double-Blinded, Placebo-Controlled Study with Randomized Withdrawal

Abstract not available.

Efficacy of risankizumab in patients with moderate-to-severe plaque psoriasis by baseline demographics, disease characteristics and prior biologic therapy: an integrated analysis of the phase III UltIMMa-1 and UltIMMa-2 studies

BACKGROUND

Risankizumab is a humanized IgG monoclonal antibody that selectively inhibits interleukin-23 through binding the p19 subunit. In Phase 3 trials, risankizumab demonstrated superior efficacy compared with adalimumab and ustekinumab in patients with moderate-to-severe plaque psoriasis. Here, we evaluated the impact of baseline characteristics on efficacy of risankizumab compared with ustekinumab in patients with moderate-to-severe plaque psoriasis.

METHODS

This analysis included all patients initially randomized to risankizumab or ustekinumab from the replicate, double-blinded, randomized, placebo-controlled phase 3 trials, UltIMMa-1 (NCT02684370) and UltIMMa-2 (NCT02684357). Patients received either risankizumab (150 mg) or ustekinumab (weight-based; 45 or 90 mg per label) at weeks 0, 4, 16, 28 and 40. Efficacy was assessed as the proportion of patients achieving ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at weeks 16 and 52 by baseline patient demographics, disease characteristics and prior biologic exposure. Mean per cent improvement in PASI was calculated by body weight and body mass index at week 52. Missing efficacy data were imputed as non-responders for categorical variables and last observation carried forward for continuous variables. Logistic regression analyses assessed for interactions between treatment and five independent variables (age, sex, weight, baseline PASI score and presence of psoriatic arthritis) at both weeks 16 and 52.

RESULTS

Baseline patient demographics, disease characteristics and prior biologic exposure were similar between patients randomized to risankizumab (n = 598) and ustekinumab (n = 199). At weeks 16 and 52, risankizumab demonstrated superior efficacy compared with ustekinumab across these patient characteristics (P < 0.01). Logistic regression analyses demonstrated that risankizumab was superior to ustekinumab at weeks 16 and 52 in all models tested (P < 0.0001 for all).

CONCLUSIONS

Risankizumab demonstrated consistent and superior efficacy compared with ustekinumab regardless of patient demographics, disease characteristics or prior biologic exposure.

AB0759 FOUR-YEAR EFFICACY AND SAFETY OF GUSELKUMAB IN PSORIASIS PATIENTS WITH AND WITHOUT PSORIATIC ARTHRITIS: A POOLED ANALYSIS FROM VOYAGE 1 AND VOYAGE 2

Background:

Guselkumab (GUS), a fully human monoclonal antibody, selectively binds and blocks interleukin-23. VOYAGE 1 and VOYAGE 2 are two ongoing Phase 3, randomized, double-blind, placebo (PBO)/active comparator-controlled clinical trials of GUS in patients (pts) with moderate-to-severe psoriasis (PsO).

Objectives:

This post-hoc analysis reports pooled results through 4 years among a subgroup of moderate-to-severe PsO pts with self-reported psoriatic arthritis (PsA) at baseline.

Methods:

1829 pts were randomized to GUS 100 mg at Weeks (Wks) 0, 4, and 12, then every 8 wks (q8wk); PBO at Wks 0, 4, and 12, GUS at Wks 16 and 20 then q8wk; or adalimumab (ADA) 80 mg at Wk 0, 40 mg at Wk 1, then 40 mg q2wk until Wk 47 (VOYAGE 1) or Wk 23 (VOYAGE 2). In VOYAGE 1, all pts received open-label GUS 100 mg q8wk during Wks 52-204. VOYAGE 2 incorporated a randomized withdrawal study design, followed by open-label GUS during Wks 76-204. Pooled subgroup analyses using the combined GUS group were conducted based on self-reported PsA status at baseline. Efficacy based on Investigator Global Assessment (IGA) score and Psoriasis Area and Severity Index (PASI) response was assessed using prespecified treatment failure rules (nonresponder status for all time points after discontinuing due to lack of efficacy, worsening of PsO, or use of a prohibited treatment).

Results:

For pooled VOYAGE 1 and VOYAGE 2 pts (N=1721), combined GUS and ADA to GUS response rates at Wks 100, 156, and 204 were: PASI 90 80.6%, 80.0%, and 80.4%; PASI 100 50.1%, 49.9%, and 52.2%; IGA 0/1 83.6%, 83.3%, and 81.7%; and IGA 0 54.3%, 52.9%, and 53.9, respectively. In the pooled subgroup analysis of pts with and without PsA, response rates were similar across the Wk 100, Wk 156, and Wk 204 evaluations (Table). Rates of adverse events through Wk 204 were comparable for pts with PsA vs those without PsA at baseline.

Conclusion:

Among GUS-treated pts with moderate-to-severe PsO with and without self-reported PsA at baseline, stable, durable, and high levels of skin responses, as well as comparable safety outcomes, through 4 years were observed.

Anxiety and depression in patients with moderate-to-severe psoriasis and comparison of change from baseline after treatment with guselkumab vs. adalimumab: results from the Phase 3 VOYAGE 2 study

BACKGROUND

Anxiety and depression are clinically significant comorbidities associated with psoriasis. Improvements in psoriasis are known to decrease anxiety and depression. Guselkumab, an anti-interleukin-23 monoclonal antibody, has demonstrated efficacy and safety for the treatment of moderate-to-severe psoriasis.

OBJECTIVE

Assess improvements in anxiety and depression with guselkumab vs. placebo and adalimumab using the Hospital Anxiety and Depression Scale (HADS).

METHODS

In VOYAGE 2, a Phase 3, randomized, double-blind, placebo- and adalimumab-controlled study, patients received placebo (through week 16 followed by crossover to guselkumab), guselkumab, or adalimumab through week 24. HADS consists of two subscales measuring anxiety (HADS-A) and depression (HADS-D), with scores ranging from 0 to 21 and higher scores indicating more severe symptoms. Scores ≥8 indicate instrument-defined anxiety or depression. Severity of psoriasis was assessed using the Psoriasis Area and Severity Index (PASI).

RESULTS

Among 989 patients randomized (with baseline HADS measurements), mean HADS-A and HADS-D scores were 6.8 ± 4.2 and 5.3 ± 4.2, respectively; 38.6% of patients reported HADS-A ≥8 and 27.7% HADS-D ≥8 at baseline. At week 16, a significantly greater proportion of guselkumab patients with baseline HADS-A or HADS-D ≥8 reported HADS-A <8 (51.4% vs. 25.9%; P < 0.001) or HADS-D <8 (59.2% vs. 27.0%; P < 0.001) vs. placebo patients. At week 24, a greater proportion of guselkumab patients with baseline HADS-A or HADS-D ≥8 reported HADS-A <8 (58.4% vs. 42.9%; P = 0.028) or HADS-D <8 (59.8% vs. 46.4%; P = 0.079) vs. adalimumab patients. PASI improvements correlated with improvement in anxiety (r = 0.27; P < 0.0001) and depression (r = 0.25; P < 0.0001) scores in patients with baseline HADS-A or HADS-D ≥8. Greater improvements in HADS were also observed at week 16 in guselkumab-treated patients vs. placebo using a more stringent cut-off of HADS ≥11.

CONCLUSION

Guselkumab treatment was associated with greater improvements in symptoms of anxiety and depression scores in patients with psoriasis compared with placebo and adalimumab.

Efficacy and safety of continuous every-2-week dosing of ixekizumab over 52 weeks in patients with moderate-to-severe plaque psoriasis in a randomized phase III trial (IXORA-P)

BACKGROUND

Ixekizumab is an interleukin-17A antagonist approved for treatment of moderate-to-severe plaque psoriasis with a recommended 160-mg starting dose, then 80 mg every 2 weeks (Q2W) to week 12, and every 4 weeks (Q4W) thereafter.

OBJECTIVE

To evaluate continuous Q2W dosing over 52 weeks.

METHODS

In this phase III, multicentre, double-blinded, parallel-group trial, three ixekizumab dosing regimens were assessed for efficacy and safety at week 52 in patients with moderate-to-severe plaque psoriasis randomized at a 2 : 1 : 1 ratio to continuous Q2W (n = 611), continuous Q4W (n = 310) or dose adjustment per protocol (Q4W/Q2W, n = 306), each with a 160-mg starting dose. Dose adjustment was determined by predefined criteria to which investigators were blinded; 72 (23?5%) patients in the Q4W/Q2W group adjusted dose. Efficacy outcomes were evaluated using logistic regression.

RESULTS

Co-primary end points were met at week 52: Psoriasis Area and Severity Index 75 responses for Q2W and Q4W dose groups were 85·9% and 79·0%, respectively (P = 0·006), and static patient global assessment 0/1 responses for Q2W and Q4W dose groups were 78·6% and 70·6%, respectively (P = 0·005). Treatment-emergent and serious adverse events were comparable across dose groups.

CONCLUSIONS

Ixekizumab Q2W had higher efficacy at week 52 than ixekizumab Q4W, with no increase in safety events.

Biosimilars for psoriasis: worldwide overview of regulatory guidelines, uptake and implications for dermatology clinical practice

The introduction of biological drugs for the treatment of patients with psoriasis has revolutionized treatment paradigms and enabled numerous patients to achieve disease control with an acceptable safety profile. However, the high cost of biologics limits access to these medications for the majority of patients worldwide. In recent years, the introduction of biosimilars for inflammatory diseases has become a fast evolving field. The future use of biosimilars offers the potential for decreased cost and increased access to biologics for patients with psoriasis. For approval of biosimilars, different regulatory agencies use highly variable methods for definition, production, approval, marketing and postmarketing surveillance. Due to potential interchangeability between biologics and biosimilars, traceability and pharmacovigilance are required to collect accurate data about adverse events in patients with psoriasis; spontaneous reporting, registries and use of 'big data' should facilitate this process on a global basis. The current article describes biosimilar regulatory guidelines and examples of biosimilar uptake in clinical practice in several countries around the world. As it is apparent that biological therapy treatment decisions may become more physician independent, the International Psoriasis Council recommends that dermatologists should take an active role in the development of biosimilar prescribing policies with their respective healthcare settings and government agencies.

Diversity of Flea (Siphonaptera) Parasites on Red Foxes (Vulpes vulpes) in Romania

Red foxes (Vulpes vulpes (L.)) are widespread across Europe, tolerant of synanthropic ecosystems, and susceptible to diseases potentially shared with humans and other animals. We describe flea fauna on red foxes in Romania, a large, ecologically diverse country, in part because fleas may serve as an indicator of the risk of spillover of vector-borne disease. We found 912 individual fleas of seven species on the 305 foxes assessed, for an infestation prevalence of 49.5%. Mean flea load per fox was 5.8 (range 0-44 fleas), and flea detections were most abundant in fall and early spring. Fleas included generalists (Ctenocephalides canis (Curtis), 32.6% of all fleas), Ct. felis (Bouché, 0.1%), and Pulex irritans L. (29.9%), the fox specialist Chaetopsylla globiceps (Taschenberg, 32.5%), mesocarnivore fleas Paraceras melis Walker (3.2%) and Ch. trichosa Kohaut (1.5%), and the small mammal flea Ctenophthalmus assimilis (Taschenberg, 0.1%), which is rarely or never reported from carnivores. There were significantly more female than male Ch. globiceps, Ct. canis, and Pu. irritans, and these three species were the most broadly distributed geographically. Diversity indices suggested reduced diversity in mountainous areas above 700 m. When compared to other flea studies on foxes in Europe, Romania had flea diversity near the median of reports, which was unexpected given Romania's high ecological diversity. Notably absent prey specialists, compared to other studies, include Archaeopsylla erinacei (Bouché) and Spilopsyllus cuniculi (Dale). Further studies of possible disease agents in fox fleas could help elucidate possible risks of vector-borne disease in foxes, domestic animals, and humans as well.

Management of thyroid eye disease in the United Kingdom: A multi-centre thyroid eye disease audit

This article aims to provide baseline data and highlight any major deficiencies in the current level of care provided for adult patients with thyroid eye disease (TED). We undertook a prospective, nonrandomized cross-sectional multicenter observational study. During a 3-month period June-August 2014, consecutive adult patients with TED who presented to nominated specialist eye clinics in the United Kingdom, completed a standardized questionnaire. Main outcome measures were: demographics, time from diagnosis to referral to tertiary centre, time from referral to review in specialist eye clinic, management of thyroid dysfunction, radioiodine and provision of steroid prophylaxis, smoking, and TED classification. 91 patients (mean age 47.88 years) were included. Female-to-male ratio was 6:1. Mean time since first symptoms of TED = 27.92 (73.71) months; from first visit to any doctor with symptoms to diagnosis = 9.37 (26.03) months; from hyperthyroidism diagnosis to euthyroidism 12.45 (16.81) months. First, 13% had received radioiodine. All those with active TED received prophylactic steroids. Seven patients who received radioiodine and did not have TED at the time went on to develop it. Then, 60% patients were current or ex-smokers. 63% current smokers had been offered smoking cessation advice. 65% patients had active TED; 4% had sight-threatening TED. A large proportion of patients (54%) were unaware of their thyroid status. Not enough patients are being provided with smoking cessation advice and information on the impact of smoking on TED and control of thyroid function.

Ixekizumab treatment improves fingernail psoriasis in patients with moderate-to-severe psoriasis: results from the randomized, controlled and open-label phases of UNCOVER-3

BACKGROUND

Fingernail psoriasis is difficult to treat.

OBJECTIVE

The objective was to evaluate the effect of ixekizumab, a monoclonal antibody selectively targeting IL-17A, on fingernail psoriasis.

METHODS

This Phase 3, double-blind trial (UNCOVER-3) randomized patients to placebo, etanercept (50-mg twice weekly), or 80 mg ixekizumab as one injection every 4 (IXE Q4W) or 2 weeks (IXE Q2W) after a 160-mg starting dose. At Week 12, ixekizumab patients received open-label IXE Q4W through Week 60; placebo patients received a 160-mg starting ixekizumab dose and etanercept patients a 4-week placebo washout before starting IXE Q4W. Efficacy was assessed by mean per cent Nail Psoriasis Severity Index (NAPSI) improvement at Weeks 12 and 60.

RESULTS

Of 1346 patients in the UNCOVER-3 trial, this subgroup analysis included only patients with baseline fingernail psoriasis: 116 (60.1%) placebo, 236 (61.8%) etanercept, 228 (59.1%) IXE Q4W and 229 (59.5%) IXE Q2W. At Week 12, greater mean per cent NAPSI improvements were achieved in IXE Q4W (36.7%) and IXE Q2W (35.2%) vs. placebo (-34.3%, P < 0.001 each comparison) and etanercept (20.0%, P = 0.048 vs. Q4W, P = 0.072 vs. Q2W). At Week 60, mean per cent NAPSI improvement was >80% regardless of initial treatment. At Week 12 (nonresponder imputation), complete resolution (NAPSI = 0) was achieved in 19.7% (IXE Q4W), 17.5% (IXE Q2W), 4.3% (placebo, P < 0.001 each comparison) and 10.2% (etanercept, P < 0.05 each comparison) of patients. By Week 60, >50% of patients achieved complete resolution.

CONCLUSIONS

At Week 12, significant improvements in fingernail psoriasis were achieved with ixekizumab therapy. With IXE Q4W maintenance dosing, additional improvement was demonstrated through 60 weeks, and >50% of patients achieved complete resolution. Registered at clinicaltrials.gov: NCT01646177.

Apremilast, an oral phosphodiesterase 4 inhibitor, improves patient-reported outcomes in the treatment of moderate to severe psoriasis: results of two phase III randomized, controlled trials

Background

Apremilast, an oral phosphodiesterase 4 inhibitor, has an acceptable safety profile and is effective for treatment of plaque psoriasis and psoriatic arthritis.

Objectives

To evaluate the impact of apremilast on health‐related quality of life (HRQOL), general functioning and mental health using patient‐reported outcome (PRO) assessments among patients with moderate to severe plaque psoriasis in the ESTEEM 1 and 2 trials.

Methods

A total of 1255 patients were randomized (2 : 1) to apremilast 30 mg BID or placebo for 16 weeks; all received apremilast through Week 32. PRO assessments included the Dermatology Life Quality Index (DLQI), 36‐Item Short‐Form Health Survey version 2 mental/physical component summary scores (SF‐36v2 MCS/PCS), Patient Health Questionnaire‐8 (PHQ‐8), EuroQol‐5D (EQ‐5D) and Work Limitations Questionnaire‐25 (WLQ‐25). Post hoc analyses examined relationships between Psoriasis Area and Severity Index (PASI) scores and PHQ‐8 in the apremilast‐treated population at Week 16.

Results

Treatment with apremilast improved all HRQOL PROs at Week 16 (vs. placebo), except the SF‐36v2 PCS, and improvements were sustained through Week 32. Mean DLQI and SF‐36v2 MCS improvements exceeded minimal clinically important differences. Changes at Week 16 in PHQ‐8 and PASI were weakly correlated, and only 35.8% of patients who achieved a ≥75% reduction from baseline in PASI score (PASI‐75) with apremilast treatment also achieved PHQ‐8 scores of 0–4.

Conclusions

Apremilast led to improvements in HRQOL PROs vs. placebo in patients with moderate to severe plaque psoriasis.

Tofacitinib withdrawal and retreatment in moderate-to-severe chronic plaque psoriasis: a randomized controlled trial

BACKGROUND

Tofacitinib is an oral Janus kinase inhibitor being investigated for the treatment of moderate-to-severe plaque psoriasis.

OBJECTIVES

To compare outcomes following tofacitinib withdrawal with outcomes of continuation.

METHODS

In this phase 3 study (NCT01186744), patients received tofacitinib 5 mg (n = 331) or 10 mg (n = 335) twice daily for 24 weeks. The patients who achieved both ≥ 75% reduction in Psoriasis Area and Severity Index (PASI 75) score from baseline and Physician's Global Assessment (PGA) of 'clear' or 'almost clear' (PGA response) received a placebo (withdrawal) or the previous dose. At relapse (> 50% reduction in the PASI improvement during initial treatment) or week 40, the patients received the initial dose.

RESULTS

Initial treatment: 33·5% and 55·2% achieved both PASI 75 and PGA responses with tofacitinib 5 and 10 mg twice daily, respectively, making them eligible for the treatment-withdrawal period. Withdrawal: 56·2%, 62·3%, 23·3% and 26·1% maintained PASI 75 responses with tofacitinib 5, 10 mg, placebo (5 mg) and placebo (10 mg) twice daily, respectively; 49·9%, 63·9%, 22·9% and 18·0% maintained PGA responses; and 92·3%, 93·0%, 32·8% and 42·9% did not relapse. Elevations in low-density lipoprotein-cholesterol levels following initial treatment (mean increase: 8·71 mg dL(-1) with 5 mg twice daily, 10·26 mg dL(-1) with 10 mg twice daily) were reversed upon withdrawal. Retreatment: 36·8% and 61·0% of patients who relapsed achieved PASI 75 responses with tofacitinib 5 or 10 mg after 16 weeks; 44·8% and 57·1% regained PGA responses.

CONCLUSIONS

Patients who received continuous treatment maintained a response more effectively when compared with placebo recipients. Safety profiles were comparable in both the continuous treatment group and retreatment group. Of those patients who relapsed, up to 60% recaptured a response with tofacitinib.

Pain in multiple sclerosis: a systematic review of neuroimaging studies

Introduction

While pain in multiple sclerosis (MS) is common, in many cases the precise mechanisms are unclear. Neuroimaging studies could have a valuable role in investigating the aetiology of pain syndromes. The aim of this review was to synthesise and appraise the current literature on neuroimaging studies of pain syndromes in MS.

Methods

We systematically searched PubMed and Scopus from their inception dates to the 2nd of April 2013. Studies were selected by predefined inclusion and exclusion criteria. Methodological quality was appraised. Descriptive statistical analysis was conducted.

Results

We identified 38 studies of variable methodology and quality. All studies but one used conventional structural magnetic resonance imaging, and the majority reported a positive association between location of demyelinating lesions and specific neuropathic pain syndromes. Most investigated headache and facial pain, with more common pain syndromes such as limb pain being relatively understudied. We identified a number of methodological concerns, which along with variable study design and reporting limit our ability to synthesise data. Higher quality studies were however less likely to report positive associations of lesion distribution to pain syndromes.

Conclusions

Further high quality hypothesis-driven neuroimaging studies of pain syndromes in MS are required to clarify pain mechanisms, particularly for the commonest pain syndromes.

•

We reviewed neuroimaging studies of pain syndromes in multiple sclerosis (MS).

•

All studies investigated neuropathic pain or headache, mainly using structural MRI.

•

Most reported associations between location of demyelinating lesions and pain.

•

Culprit lesions were most commonly reported in the brainstem.

•

High quality hypothesis-driven neuroimaging studies of pain in MS are still needed.

Simulated games activity vs continuous running exercise: a novel comparison of the glycemic and metabolic responses in T1DM patients

To compare the glycemic and metabolic responses to simulated intermittent games activity and continuous running exercise in type 1 diabetes. Nine patients (seven male, two female; 35 ± 4 years; HbA1c 8.1 ± 0.2%/65 ± 2 mmol/mol) treated on a basal-bolus regimen completed two main trials, a continuous treadmill run (CON) or an intermittent running protocol (INT). Patients arrived to the laboratory fasted at ∼ 08:00 h, replicating their usual pre-exercise meal and administering a 50% reduced dose of rapid-acting insulin before exercising. Blood glucose (BG), K(+) , Na(++) , pH, triglycerides, serum cortisol and NEFA were measured at baseline and for 60 min post-exercise. Interstitial glucose was measured for a further 23 h under free-living conditions. Following exercise, BG declined under both conditions but was less under INT (INT -1.1 ± 1.4 vs CON -5.3 ± 0.4 mmol/L, P = 0.037), meaning more patients experienced hypoglycemia (BG ≤ 3.5 mmol/L; CON n = 3 vs INT n = 2) but less hyperglycemia (BG ≥ 10.9 mmol/L; CON n = 0 vs INT n = 6) under CON. Blood lactate was significantly greater, and pH lower, with a temporal delay in K(+) under INT (P < 0.05). No conditional differences were observed in other measures during this time, or in interstitial glucose concentrations during the remaining 23 h after exercise. Simulated games activity carries a lower risk of early, but not late-onset hypoglycemia than continuous running exercise in type 1 diabetes.

Running behind a tourist: leisure-related skin cancer prophylaxis

The most important risk factor in the development of skin cancer is exposure to ultraviolet (UV) radiation. Cumulative lifetime UV radiation exposure has been shown to be most important in the pathogenesis of squamous cell carcinoma, whereas intermittent high-dose UV radiation exposure in childhood and adolescence may be more important in the aetiology of basal cell carcinoma and cutaneous malignant melanoma. Using established methodology and best available estimates on UV-related mortality and morbidity, it has been estimated that annually around 1·5 million disability-adjusted life years are lost through excessive exposure to UV radiation. Skin cancer is a significant health problem and its burden is such that it causes the health system more to treat than any other forms of cancer. Prevention is the key action in managing skin cancer at a population level. Investment in prevention programmes such as SunSmart encourages protective behaviours that will reduce the human and financial costs of skin cancer.

MAO-B inhibitors: multiple roles in the therapy of neurodegenerative disorders?

Monoamine oxidases play a central role in catecholamine catabolism in the central nervous system. The biochemical and pharmacological properties of inhibitors of the monoamine oxidase type B are reviewed. The evidence for biochemical activities distinct from their ability to inhibit MAO-B is discussed, including possible antioxidative and antiapoptotic activities of these agents. The significance of these properties for the pharmacological management of Parkinson's disease and the evidence for a neuroprotective effect of one such agent (selegiline) is also discussed.

Left hemispheric reductions of regional cerebral blood flow (rCBF) correlate with measures of dementia severity in patients with Alzheimer's disease: a SPECT study

Regional cerebral blood flow (rCBF) values were measured by single photon emission computed tomography (SPECT) in different regions of the brain in 27 patients with DAT. Significant correlations were found between rCBF in left parieto-temporooccipital regions and psychometric test scores. Patients with hemisphere asymmetry in SPECT performed worse on psychometric tests. SPECT did not permit prediction of or differentiation between depressive and psychotic symptoms.

Skin cancer prevention in Australia

Australia has one of the highest skin cancer incidence and mortality rates in the world. The reason for these high rates is due in part to the high ambient UV radiation levels, combined with a predominantly susceptible fair-skinned population. To address this problem, since 1980 Australians have been exposed to social marketing campaigns to raise awareness of skin cancer prevention. These campaigns have used mass media alongside interventions in schools, workplaces, and in community and leisure settings to motivate sun protective behaviour. As a result of these interventions it can be demonstrated that social marketing campaigns can be a very effective method to not only motivate behaviour change, reduce sunburn, and increase awareness but more importantly, reduce melanoma rates and bring positive economic returns to government. However long term investment in this area is required otherwise any population gains in behaviour are very likely to be quickly eroded.
