Objective To describe adherence, persistence, discontinuation, restarting, switching, dosing, and health care costs among patients with psoriatic arthritis (PsA) treated with ixekizumab (IXE). Methods MarketScan administrative claims databases were used to select adults (≥18 years) initiating IXE between January 1, 2016, and June 30, 2019, for this retrospective study (earliest IXE claim = index). Eligible patients had one or more PsA diagnoses during the 12 months preceding the index and had 12 months of follow‐up time after the index. Adherence (measured by proportion of days covered [PDC]) persistence ( 0.80)to IXE prior to discontinuation. Dose values were consistent with prescribing information for patients with and without comorbid psoriasis. Although IXE costs ($5233 [SD = $2497]) accounted for 85.6% of PsA‐related health care costs, only 3.5% of IXE costs were patient out‐of‐pocket expenses. Adjusting for the ICER discounts decreased all‐cause and PsA‐related costs by $2509 PPPM. Conclusion Results from this real‐world analysis suggest that treatment patterns and costs among patients with PsA initiating IXE are consistent with prior literature for other biologics.

Objective To assess treatment patterns of Ixekizumab (IXE) and evaluate the speed of onset and long-term clinical and quality-of-life outcomes among a subset of patients who switched from adalimumab (ADA) and secukinumab (SEC) to IXE in a real-world setting. Method A retrospective chart review study was conducted at a single US dermatology referral center. Result 153 patients were included in the study, 69.3% of patients were biologic-experienced. ADA was the most commonly used biologic prior to IXE initiation. 66.7% of patients remained on IXE at the study end. 47.7% of patients received concomitant methotrexate, and usage decreased consistently after 1 month. IXE treatment duration was longer among patients who were early responders (achieved sPGA (0,1) at 1 month) vs. non-early responders. 69.4% and 43.3% of patients who switched from ADA and SEC to IXE achieved sPGA (0,1) by week 4, respectively. Conclusion Patients who switched to IXE, specifically from ADA or SEC, had rapid treatment response as well as desirable long-term outcomes. IXE persistence was longer among early responders than non-early responders. Concomitant usage of methotrexate prior to switching to IXE and as a concomitant bridging treatment was reduced after IXE initiation while the proportion of patients achieving treatment targets remained high.

Background: Real-world data on patients newly initiating ixekizumab is limited. Our study describes the characteristics of patients who initiated ixekizumab and other biologics for psoriasis treatment in North American dermatological practices. Materials & methods: Characteristics of patients ascertained at registry enrollment are described via means and frequencies. Results: Compared with other biologic initiators, ixekizumab initiators had: longer disease duration (17.1 vs 15.1 years); more were considered least severe by body surface area (33 vs 26%); moderate-to-severe by IGA (56 vs 48%); were biologic-experienced (80 vs 52%); obese (54 vs 47%); and experienced greater impact in work productivity (5.3 vs 2.9%) versus other biologic initiators. Conclusion: Psoriasis patients initiating ixekizumab had more severe disease, biologic experience, and worse patient-reported outcomes than those initiating other biologics.

BACKGROUND: Measuring cumulative clinical treatment benefit over time captures speed and magnitude of effects. Assessing the cost of biologics relative to their cumulative clinical benefits versus a single time point represents an alternative to evaluate the value of a given biologic used to treat psoriasis. OBJECTIVE: To compare cumulative benefit and cost per cumulative benefit of biologics in treatment of moderate to severe psoriasis from a network meta-analysis (NMA). METHODS: Biologics included in the analysis were ixekizumab, adalimumab, guselkumab, ustekinumab, secukinumab, risankizumab, and certolizumab pegol. Psoriasis Area and Severity Index (PASI) responses over the initial 16-week treatment period were obtained from 31 articles. Cumulative benefits for PASI 75, PASI 90, and PASI 100 responses were measured as area under the curve (AUC) using the trapezoidal method. Bayesian-based NMA modeled percent maximum AUC through week 16 (%Max_AUCW16). The AUC estimates over 16 weeks were converted to total skin clearance threshold days achieved for PASI 75, PASI 90, and PASI 100 with each biologic. Cost per cumulative benefit was estimated by multiplying number of doses (per FDA label) by nationally representative discounted wholesale acquisition costs (WACs) for 16 weeks of treatment divided by %Max_AUCW16. The primary cost analysis used WACs, including week 16 doses. Co-primary cost analysis used discounted WACs, including week 16 doses. Sensitivity analysis was conducted using WACs and discounted WACs, excluding doses administered at week 16. RESULTS: Among biologics with available week 16 AUC data for PASI 90 and PASI 100, cumulative benefits over the initial 16-week treatment period ranged from 20.2% (certolizumab pegol) to 47.0% (ixekizumab) for PASI 90 and from 7.4% (adalimumab) to 22.2% (ixekizumab) for PASI 100. The total number of estimated PASI 90 and PASI 100 days achieved over the first 16 weeks of treatment was highest with ixekizumab (53 days and 25 days, respectively). In the primary analysis, guselkumab had the lowest cost per cumulative benefit (95% credible interval [CrI]; $99,742 [$89,941-$111,653]), followed by ixekizumab ($108,906 [$95,928-$126,093]) and adalimumab ($111,233 [$97,549-$129,022]) for PASI 90, and ixekizumab had the lowest cost per cumulative benefit ($230,884 [$191,611-$291,115]), followed by secukinumab ($238,945 [$204,029-$288,072]) and risankizumab ($279,968 [$250,683-$316,872]) for PASI 100 responses. In the co-primary analysis, ixekizumab had the lowest discounted cost per AUC (95% CrI; $60,988 [$53,719-$70,612]), followed by guselkumab ($66,827 [$60,260-$74,807]) and secukinumab ($69,622 [$61,783-$79,786]) for PASI 90, and ixekizumab had the lowest cost per cumulative benefit ($129,295 [$107,302-$163,024]), followed by secukinumab ($148,146 [$126,498-$178,605]) and guselkumab ($188,190 [$166,791-$215,969]) for PASI 100 responses. Conclusions: Among biologics studied, ixekizumab demonstrated the greatest cumulative clinical benefit, maintaining the lowest cost per cumulative benefit for PASI 100 responses and lowest discounted cost per cumulative benefit for PASI 90 and PASI 100 responses for moderate to severe psoriasis over the initial 16-week treatment period.

Introduction Ixekizumab has demonstrated rapid onset of action, high levels of skin clearance, and improvements in quality of life in patients with moderate-to-severe psoriasis, including plaque, erythrodermic, or generalized pustular psoriasis. Methods This was a post hoc analysis of UNCOVER-J, a phase 3, multicenter, single-arm, open-label study of ixekizumab for treatment of Japanese patients with psoriasis. The objective was to assess the proportion of patients who achieved Dermatology Life Quality Index (DLQI) (0,1) and Itch Numeric Rating Scale (NRS) (0) at weeks 4 and 12 according to Psoriasis Area and Severity Index (PASI) percentage improvement levels. All intent-to-treat patients with plaque, erythrodermic, or generalized pustular psoriasis were analyzed. Results A total of 91 patients were treated with ixekizumab and included in the analysis. Rapid improvements in PASI at weeks 4 and 12 were associated with improvements in DLQI (0,1) response at week 4 and at week 12. Complete skin clearance (PASI 100) achieved either at week 4 or week 12 was associated with a higher Itch NRS (0) response at week 12. Conclusions Patients with rapid improvement in clinical symptoms of psoriasis had better patient outcomes than those with slower responses. These findings highlight the clinical importance of achieving a fast response in patients with psoriasis, which may lead to better treatment outcomes.

Background Cumulative clinical improvement and speed of improvement are important to psoriasis patients. Objective Compare cumulative benefits of biologics over 12 to 16 weeks in the treatment of moderate to severe psoriasis. Methods A systematic literature review identified phase III trial data on Psoriasis Area and Severity Index (PASI) responses for biologics during 12 and 16 weeks of treatment. Cumulative clinical benefit, measured by the area under the curve for PASI ≥75% improvement (PASI 75), ≥90% improvement (PASI 90), and 100% improvement (PASI 100), was compared using the network meta-analysis and Bayesian methodology on the relative probability of achieving percentage of maximum area under the curve. Results Among biologics approved for psoriasis treatment, anti–interleukin-17 biologics demonstrated consistently greater cumulative clinical benefits on PASI 75, PASI 90, and PASI 100 over the 12- or 16-week period than anti–interleukin-23 and other biologics. For biologics with 12-week data, ixekizumab and brodalumab showed greater cumulative benefits for PASI 75, PASI 90, and PASI 100 than secukinumab, followed by guselkumab, infliximab, adalimumab, ustekinumab, and etanercept. Ixekizumab showed greater cumulative benefits than all other biologics reporting 16-week data. Limitations Recently approved biologics were not included. Conclusion Ixekizumab (at 12 weeks and 16 weeks) and brodalumab (at 12 weeks) had greater cumulative clinical benefit than all of other biologics studied.

Real-world data on treatment patterns associated with use of interleukin-17A inhibitors in psoriasis are lacking.To compare treatment patterns between ixekizumab or secukinumab users in clinical practice.A retrospective cohort study included patients with psoriasis aged ≥18 years treated with ixekizumab or secukinumab between March 1, 2016, and May 31, 2018 in IBM MarketScan (IBM Corp, Armonk, NY) databases. Inverse probability of treatment weighting and multivariable models were used to address cohort imbalances and estimate the risks of nonpersistence (60-day gap), discontinuation (≥90-day gap), switching, and the odds of adherence.The study monitored 645 ixekizumab users for 13.7 months and 1152 secukinumab users for 16.3 months. Ixekizumab users showed higher persistence rate (54.8% vs 45.1%, P .001) and lower discontinuation rate (37.8% vs 47.5%, P .001) than secukinumab. After multivariable adjustment, ixekizumab users had lower risks of nonpersistence (hazard ratio, 0.82; 95% confidence interval, 0.71-0.95) and discontinuation (hazard ratio, 0.82; 95% confidence interval, 0.70-0.96), and higher odds of high adherence to treatment measured by a medication possession ratio ≥80% (hazard ratio, 1.31; 95% confidence interval, 1.07-1.60). The risk of switching was similar between cohorts.Disease severity and clinical outcomes were unavailable.Ixekizumab users demonstrated longer drug persistence, lower discontinuation rate and risk of discontinuation, higher likelihood of adherence, and similar risk of switching compared with secukinumab users in clinical practices.

Objective To evaluate the effect of ixekizumab on self-reported functioning and health in patients with active nonradiographic axial spondyloarthritis (SpA). Methods COAST-X was a randomized, controlled trial conducted in patients with nonradiographic axial SpA over 52 weeks. Participants were randomized at a ratio of 1:1:1 to receive 80 mg of ixekizumab subcutaneously every 4 weeks or 2 weeks or placebo for 52 weeks. Self-reported functioning and health end points included the Medical Outcomes Study Short Form 36 (SF-36) health survey, Assessment of Spondyloarthritis International Society (ASAS) health index, and European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) health-utility descriptive system. Results Compared to placebo, ixekizumab treatment resulted in improvement of SF-36 physical component summary scores from baseline, with a score of 4.7 improving to 8.9 with ixekizumab therapy every 4 weeks (P < 0.05) and a score of 9.3 with ixekizumab therapy every 2 weeks (P < 0.01); the greatest improvements were observed in the domains of physical functioning, role-physical, and bodily pain at weeks 16 and 52. A higher proportion of patients receiving ixekizumab therapy every 2 weeks reported >= 3 improvements based on the ASAS health index from baseline to weeks 16 and 52 (P < 0.05). Significantly more patients receiving ixekizumab every 4 weeks reported improvements in "good health status" on the ASAS health index (ASAS score of

Background There is lack of real-world treatment pattern comparison data between ixekizumab and adalimumab which are approved for the treatment of moderate-to-severe plaque psoriasis. Objective To compare real-world treatment patterns among psoriasis patients initiating ixekizumab or adalimumab in the United States. Methods Psoriasis patients with ≥1 claim for ixekizumab or adalimumab between March 1, 2016, and May 31, 2018, were identified (index date = date of first ixekizumab or adalimumab claim) from the IBM Watson Health MarketScan® databases. Patients were required to be continuously enrolled for ≥12 months before the index date and followed for a minimum of 6 months until inpatient death, enrollment end, or study end, whichever occurred first. Treatment persistence, adherence, discontinuation, restart, and switching were analyzed. Inverse probability of treatment weighting and multivariable regression modeling were employed to address cohort imbalances and estimate the adjusted risk of non-persistence, discontinuation, and switching, and the odds of adherence. Results A total of 646 ixekizumab and 3668 adalimumab users were included and followed for a mean of 14.0 and 16.5 months, respectively. Compared to adalimumab, ixekizumab was associated with 19% lower risk of non-persistence (hazard ratio [HR]=0.81, 95% confidence interval [CI]: 0.69-0.95), 26% lower risk of discontinuation (HR=0.74, 95% CI: 0.62-0.88), and 28% lower risk of switching (HR=0.72, 95% CI: 0.57-0.91). Ixekizumab users had higher odds of medication possession ratio ≥80% (odds ratio [OR]=1.36, 95% CI: 1.10-1.69) but similar odds by proportion of days covered ≥80% (OR=1.22, 95% CI: 0.98-1.53). Conclusion Psoriasis patients treated with ixekizumab demonstrated longer persistency, higher adherence and were less likely to discontinue or switch treatment compared to adalimumab users. However, while patients achieving highly adherent threshold significantly differed by MPR ≥80%, it did not by PDC ≥80%; hence, further analysis using fixed-length follow-up is required.

Introduction Real-world data comparing effectiveness of ixekizumab (IXE) and secukinumab (SEC) among biologic-experienced patients are limited. This study compared treatment patterns over 18 months among biologic-experienced patients with psoriasis receiving IXE or SEC in the USA. Methods A retrospective observational study using administrative claims data from IBM® Watson Health MarketScan® Research Databases included adult patients with ≥ 1 inpatient or ≥ 2 non-diagnostic (≥ 30 days apart) outpatient claim/s with diagnosis of psoriasis between March 1, 2015 and October 31, 2019, and ≥ 1 claim/s for index drugs, IXE or SEC, between March 1, 2016 and October 31, 2019. Patients had to have ≥ 1 claim/s for biologics indicated for psoriasis in the 6-month pre-period. During the 18-month follow-up, treatment adherence (proportion of days covered [PDC]), high adherence (PDC ≥ 80%), persistence, discontinuation, reinitiation, and switching were assessed. To address cohort imbalances, inverse probability of treatment weighting was employed. Logistic regression was used to estimate odds ratio for high adherence. Cox proportional hazard models were used to estimate hazard ratio for non-persistence, discontinuation, and switching. Results Overall, 411 IXE and 780 SEC users were included. After weighting, IXE users had significantly higher rate of high treatment adherence (42% vs. 35%, p = 0.019), higher persistence rate (44.9% vs. 36.9%, p = 0.007), lower discontinuation rate (48.4% vs. 56.0%, p = 0.012), and lower switching rate (26.6% vs. 34.0%, p = 0.009) compared with SEC users. After multivariable adjustment, compared with SEC, IXE use was associated with 36% higher odds of high treatment adherence (OR 1.36, 95% CI 1.05–1.74), 20% lower risk of treatment non-persistence (HR 0.80, 95% CI 0.68–0.93), 19% lower risk of discontinuation (HR 0.81, 95% CI 0.68–0.96), and 25% lower risk of switching (HR 0.75, 95% CI 0.60–0.93). Conclusion This study suggests that IXE treatment is associated with significantly higher adherence rates and significantly lower non-persistence, discontinuation, and switching compared with SEC treatment.

Introduction Alopecia areata (AA) is an autoimmune disorder causing sudden, non-scarring hair loss. There are currently no drugs approved for AA treatment. This study assessed prevalence of comorbidities, treatments, and healthcare costs and resource utilization among patients with AA in the USA. Methods Patients diagnosed with AA between January 2011 and December 2018 were identified in IBM MarketScan® Research Databases. Eligible patients had no other hair loss-related disorders and were continuously enrolled with medical and pharmacy benefits at least 12 months before and after AA diagnosis. Descriptive statistics were used to summarize comorbid conditions, treatments related to AA or other autoimmune/inflammatory conditions, and all-cause and AA-specific healthcare costs and resource utilization identified from claims data. Results A total of 68,121 patients with AA were identified. Mean (SD) age was 40.3 (17.8) years and 61.0% were female. The most common comorbidities included hyperlipidemia (22.4%), hypertension (21.8%), thyroid disorders (13.1%), contact dermatitis or eczema (10.8%), depression (9.5%), and anxiety (8.4%). Comorbid autoimmune diseases included atopic dermatitis (2.8%), psoriasis (2.1%), chronic urticaria (1.5%), and rheumatoid arthritis (1.1%). During the 12-month follow-up period, 37,995 patients (55.8%) were prescribed treatment for their AA or other comorbid autoimmune/inflammatory disease; 44.9% of treated patients were prescribed therapy within 7 days of AA diagnosis. Of patients receiving treatment, 80.3% received topical steroids and 30.0% received oral steroids. Mean (SD) total healthcare costs were $11,241.21 ($43,839.69) for all-causes and $419.12 ($1534.99) for AA. AA-related expenses were driven by outpatient and prescription costs. Conclusion Patients with AA have a high comorbidity burden and lack of treatment. Current AA treatments, including systemic therapies other than oral steroids, were not frequently utilized in this study population. Healthcare costs incurred by patients with AA went beyond AA-related expenses. Longitudinal data are needed to better understand treatment trajectories and the disease burden in patients with AA.

Background Real-world data on long-term treatment patterns associated with interleukin-17A inhibitors in plaque psoriasis are lacking. Objective To compare ixekizumab or secukinumab treatment patterns over a 24-month period among plaque psoriasis patients. Methods Adult patients with psoriasis who had 1 or more claims for ixekizumab or secukinumab between March 1, 2016, and October 31, 2019, and with 24 months of follow-up after starting treatment were identified from IBM MarketScan claims databases. Inverse probability of treatment weighting and multivariable models were employed to balance cohorts and estimate the risks of nonpersistence, discontinuation, and switching and odds of highly adherent treatment (proportion of days covered ≥ 80%). Results A total of 471 ixekizumab and 990 secukinumab users were included. Compared to secukinumab, ixekizumab use was associated with a 20% lower risk of nonpersistence (hazard ratio, 0.80; 95% CI, 0.70-0.92), a 17% lower risk of discontinuation (hazard ratio, 0.83; 95% CI, 0.72-0.96), and a 42% higher odds of being highly adherent to treatment (odds ratio, 1.42; 95% CI, 1.12-1.80). No difference in risk of switching was observed (hazard ratio, 0.83; 95% CI, 0.68-1.01). Limitations Disease severity and clinical outcomes were unavailable. Conclusion Over 24 months, ixekizumab users exhibited better persistence and adherence, and a lower risk of discontinuation than secukinumab users in real-world settings.

Introduction Patients with ankylosing spondylitis (AS) are burdened with symptoms impacting work productivity measured by presenteeism, absenteeism, overall work impairment, and activity impairment. Ixekizumab, a high-affinity monoclonal antibody selectively targeting interleukin-17A, has been demonstrated to improve disease signs and symptoms in two phase 3 trials of AS. This study investigated for 52 weeks the effect of ixekizumab treatment on work productivity in patients with active AS. Methods COAST-V (NCT02696785) and COAST-W (NCT02696798) were phase 3, multicenter, randomized, controlled trials investigating the efficacy of ixekizumab 80 mg every 4 weeks (Q4W) and every 2 weeks (Q2W) in patients with AS naïve to biologic disease-modifying antirheumatic drugs (bDMARDs; COAST-V) or who were inadequate responders or intolerant to tumor necrosis factor inhibitors (TNFi; COAST-W). Work productivity was measured with the Work Productivity and Activity Impairment Questionnaire for Spondyloarthritis at weeks 16 and 52. Absenteeism, presenteeism, and overall work impairment were assessed for patients reporting paid work. Activity impairment was assessed regardless of work status. Results At baseline, 66.2% (434/656) of patients reported paid work. At week 16, bDMARD-naïve patients treated with both ixekizumab dose regimens and TNFi-experienced patients treated with ixekizumab Q2W reported significant improvements in activity impairment (p

To compare drug survival of ixekizumab to other IL‐17 inhibitors (IL‐17i) and TNF inhibitors (TNFi) among patients with psoriasis (PsO) in a real‐world setting. Participants included adult PsO patients enrolled in the Corrona Psoriasis Registry who initiated ixekizumab, TNFi, or other IL‐17i between 16 March 2016 to 10 August 2019 and completed ≥1 follow‐up visit. Multivariable adjusted hazard ratios (HR) were calculated to estimate the risk for drug discontinuation in the ixekizumab group relative to the other drugs. Among the 1604 drug initiations, 552 initiated ixekizumab, 450 initiated TNFi, and 602 initiated other IL‐17i. Mean age was 51 years, 49% were women, and 52% were obese (BMI > 30). Ixekizumab patients had a higher proportion of patients with PASI >12 at drug initiation (24%) than TNFi (15%) and other IL‐17i (19%). Over a median of 11 months of follow‐up, 723/1604 (45%) drug discontinuations occurred. Persistence of ixekizumab, TNFi, and other IL‐17i at 24‐months were 68%, 33%, and 46%, among biologic‐naïve patients (n = 543), and 46%, 23%, and 36%, for biologic‐experienced patients (n = 1061), respectively. Ixekizumab patients had a 64% lower risk of discontinuation vs TNFi (HR = 0.36; 95% CI 0.27‐0.47) and a 31% lower risk vs other IL‐17i (HR = 0.69, 95% CI 0.55‐0.87) after adjustment for biologic experience and other covariates. HRs were similar when limited to patients with moderate‐to‐severe PsO (BSA > 3, PASI > 3, and IGA > 1, n = 1076) at initiation. In our study of real‐world patients with PsO, initiators of ixekizumab had more prolonged drug survival than both initiators of TNFi and other IL‐17i up to 2 years of follow‐up.

Background: Psoriasis is a chronic immune-mediated inflammatory skin condition that has a significant negative impact on the physical, emotional, and psychosocial well-being of those affected. Ixekizumab (IXE) has demonstrated an early and high-level treatment response in the real-world setting. This study aimed to assess the rapidity and long-term disease severity and quality of life (QOL) outcomes among IXE-treated plaque psoriasis patients. Method: A retrospective cohort study was conducted at a single US dermatology referral center. Medical charts were reviewed for adult psoriasis patients starting IXE (index date) between March 22, 2016, and February 28, 2018. Disease severity and QOL data were abstracted up to one-year pre-IXE initiation and up to 35 months post-IXE initiation. Static Physician Global Assessment (sPGA), Body Surface Area (BSA), and Dermatology Life Quality Index (DLQI) were summarized at 1-month post-index and at 3-month intervals. Logistic regressions were performed to evaluate the 1-month response in relation to long-term sPGA, BSA, DLQI outcomes. Subgroup analysis were conducted to compare outcomes among biologic naïve and biologic experienced patients.Results: A total of 153 patients (median age at index: 47.7 years; 65.4% male; 93.5% Caucasian) were included in the study. Majority of patients (69%; n=106) were biologic experienced prior to IXE initiation. In the total study cohort, at 1-month post-index 58.8% of patients achieved sPGA (0,1), 55.9% achieved DLQI (0,1), and 66.9% achieved BSA≤1%. Patients with sPGA (0,1) at 1-month post-index had greater odds of remaining sPGA (0,1) and BSA≤1% at 24-month (sPGA 0,1: OR=10.1; 95% CI: 2.1-47.9; BSA≤1%: OR=13.3; 95% CI: 2.2-80.2). Among patients who achieved sPGA (0,1) at 1-month post-index, the proportion of patients with sPGA (0,1), DLQI (0,1), and BSA≤1% remained largely the same for the 24-month follow-up. Among biologic experienced and naïve patients, more than half achieved sPGA (0,1), DLQI (0,1), and BSA≤1% at 1-month after IXE initiation. Conclusion: This real-word study demonstrated that majority of patients initiating IXE achieved sPGA (0, 1), DLQI (0, 1) and BSA ≤1% targets within the first month of treatment and were able to maintain treatment response for up to 24 months independent of prior biologic exposure.

Item does not contain fulltext BACKGROUND: Psoriasis symptoms may decrease quality of life for patients. Skin-related personal relationship difficulties in psoriasis patients are common, under-reported and poorly understood. OBJECTIVE: To assess the effect of ixekizumab (IXE) treatment on skin-related personal relationship difficulties in patients with moderate-to-severe psoriasis. METHODS: Pooled data (N = 2570) on skin-related relationship problems were obtained from two large phase 3 trials (UNCOVER-2 and UNCOVER-3) in patients with moderate-to-severe plaque psoriasis randomized to subcutaneous placebo (PBO, N = 361), etanercept (ETN; 50 mg twice weekly, N = 740), or 80 mg IXE as one injection every 4 (IXEQ4W, N = 733) or 2 weeks (IXEQ2W, N = 736) for 12 weeks, following a 160-mg initial dose. The Dermatology Life Quality Index (DLQI) Personal Relationships Domain (PRD) (Items 8 and 9) was used to assess how much the skin caused any personal relationship difficulties at weeks 0, 2, 4 and 12. Improvement was compared for IXE vs PBO and ETN using logistic models. Factors associated with improvement were assessed using multiple linear regressions. DLQI Item 9, assessing sexual difficulties, was also analysed separately. RESULTS: PRD scores (mean +/- standard deviation) at baseline were similar across all treatment groups (PBO: 1.8 +/- 1.9; ETN: 1.7 +/- 1.8; IXEQ4W: 1.6 +/- 1.8; IXEQ2W: 1.7 +/- 1.8). Treatment with IXE rapidly and significantly improved the mean PRD score compared to PBO and ETN (P < 0.001 at all time points). Baseline PRD score was the strongest negative predictor of improvement. IXE enabled significantly more patients with moderate-to-severe plaque psoriasis to reduce their skin-related sexual difficulties at Week 12 compared to PBO (P < 0.001) or ETN (P < 0.001). CONCLUSION: Ixekizumab improves patient-reported skin-related PRD difficulties in patients with moderate-to-severe psoriasis.

Background A significant gap exists in how psoriasis severity is related to validated patient-reported outcomes (PROs), which are critical in characterizing disease burden. Objective Determine the association between psoriasis severity and PROs, including health-related quality of life (HRQoL), depression, and work productivity, from patients’ perspectives. Methods An online survey using validated PRO instruments was administered in 2013. PROs included the Dermatology Life Quality Index, Quick Inventory of Depressive Symptoms-Self-Report (16 items) (QIDS-SR16), and Work Productivity and Activity Impairment Questionnaire-Psoriasis. Results The survey was completed by 1109 patients, 42% of whom had psoriatic arthritis. Respondents reported worse HRQoL and work productivity impairment with greater psoriasis severity ( p < 0.05). Similarly, there was a greater proportion of participants with moderate-or-greater depressive symptoms (QIDS-SR16 total score) among patients with increasing psoriasis severity ( p < 0.05). Conclusion Greater levels of impairment in HRQoL, work productivity, and depressive symptoms were associated with increased psoriasis severity.

Background and Objective Previous large studies have highlighted the impact of psoriasis on health-related quality of life (HRQoL) but not on interpersonal touch. This survey assessed the prevalence of touch avoidance among psoriasis patients, and its relationship to clinical characteristics and HRQoL. Methods Using an online, cross-sectional study with a standardized questionnaire, psoriasis patients reported their level of touch avoidance. The relationships between touch avoidance, patient-reported outcome measures, and patient demographics were analyzed using linear models for continuous outcomes and logistic models for categorical outcomes. Results Touch avoidance was reported by 48.2% of participants. Higher levels of touch avoidance were associated with worse HRQoL, depression, and itch outcomes (pConclusion Nearly half of psoriasis patients report avoidance of touch. Those who had worse disease severity, HRQoL, and depression reported higher levels of touch avoidance.

As more biologics become available for the treatment of psoriasis (PsO), there is a lack of direct comparisons of health care costs between patients who are treated by different medications, including ixekizumab (IXE), secukinumab (SEC), and adalimumab (ADA).To compare the real-world health care costs of patients with PsO initiating IXE with those of patients initiating either SEC or ADA.Patients diagnosed with PsO between July 1, 2015, and May 31, 2018, were identified from the IBM MarketScan commercial and Medicare databases. Two weighted patient sample sets were constructed based on drug claims between March 1, 2016, and May 31, 2018: IXE versus SEC and IXE versus ADA. Within each sample, the first claim of eligible drugs was set as the index date. Patients were aged ≥ 18 years and had ≥ 12 months of continuous eligibility before and after the index date. Patients with other indications for the index drug in the preperiod or with use of the index drug within 90 days before the index date were excluded. Inverse probability of treatment weighting (IPTW) was employed to balance cohorts. All-cause and PsO-related health care costs per member per month (PMPM) incurred during the 12-month follow-up period were assessed. Monthly PsO-related pharmacy costs were adjusted using drug discount rates published by the Institute for Clinical and Economic Review (ICER). Annual index drug costs were estimated by adjusting for medication possession ratio and ICER discount rates. All costs were weighted by IPTW.Two study samples were identified: 357 IXE users were compared with 763 SEC users, and 388 IXE users were separately compared with 2,578 ADA users. Before weighting, IXE users were demographically and clinically similar to SEC users but were older and had worse health status than ADA users. Cohorts were balanced postweighting. After weighting, mean monthly all-cause health care costs were $7,313 and $6,477 (After adjusting for drug discount programs (through application of ICER discount rate), this real-world study estimated that average monthly PsO-related costs during the first year of treatment were similar between patients treated with IXE compared with those treated with SEC or ADA.Funding for this study was provided to IBM Watson Health by Eli Lilly and Company. The analysis was conducted independently by IBM Watson Health. Eli Lilly and Company and IBM Watson Health collaborated on study design and interpretation of results.

To assess improvements in health-related quality of life (HRQoL) with ixekizumab treatment in patients with moderate-to-severe psoriasis. Adults with plaque psoriasis were enrolled in phase III, double-blind, randomised, controlled trials (UNCOVER-1, UNCOVER-2, or UNCOVER-3). All 3 protocols included a 12-week, placebo-controlled induction period; UNCOVER-2 and UNCOVER-3 also had an active-control group (50 mg etanercept) during induction. After induction, patients in UNCOVER-1 and UNCOVER-2 entered a 48-week withdrawal (maintenance) period (Weeks 12–60), during which Week-12 sPGA (0,1) responders were rerandomized to receive placebo, or 80 mg ixekizumab every 4 weeks (Q4W) or 12 weeks. As a secondary objective, HRQoL was measured by the generic Medical Outcomes Survey Short Form-36 (SF-36) at baseline and Weeks 12 and 60. Changes in mean SF-36 Physical and Mental Component Summary (PCS and MCS) and domain scores and proportions of patients reporting improvements ≥ minimal important differences in SF-36 scores were compared between groups. At Week 12, ixekizumab-treated patients (both dose groups in UNCOVER-1, -2, and -3) reported statistically significantly greater improvements in mean SF-36 PCS and MCS and all 8 SF-36 domain scores versus placebo. Further, more ixekizumab-treated patients than placebo-treated patients reported at least minimal treatment responses in SF-36 PCS and MCS scores and domain scores. Overall improvements in SF-36 PCS and MCS scores were maintained through Week 60. Ixekizumab-treated patients reported statistically significant improvements in HRQoL at 12 weeks that persisted through 1 year.

The incremental benefits of obtaining higher levels of skin clearance for patients with psoriasis have been established across several patient reported outcomes (PROs). Patients who obtain clear or almost clear skin are more likely to report no impact of psoriasis on health-related quality of life (HRQoL) and other symptom measures. While the benefits of obtaining higher skin clearance have been reported with different therapeutic agents, the question of whether the benefits of such high levels of response may be offset by an increased risk for adverse outcomes has not been fully explored with biologics.

Evidence of the cost-efficacy of ixekizumab for the treatment of moderate-to-severe plaque psoriasis (PsO) in the US is limited.To estimate the number needed to treat (NNT) and monthly cost of achieving one additional Psoriasis Area and Severity Index (PASI) 75, 90, and 100 responder for ixekizumab and other Food and Drug Administration (FDA)-approved biologics in PsO.A network meta-analysis estimated the probability of achieving PASI 75, 90, or 100 response during induction for each biologic. NNTs were calculated using response difference of each respective biologic vs placebo at the end of induction. Monthly costs per additional PASI responder were based on FDA-approved doses, wholesale acquisition costs, and induction NNTs.Induction NNTs for ixekizumab 80 mg once every 2 weeks (Q2W) relative to placebo were consistently lower across all levels of clearance compared with the other biologics. Monthly cost per additional responder was lowest for ustekinumab 45 mg at PASI 75 and for secukinumab 300 mg and ixekizumab 80 mg Q2W at PASI 90. Ixekizumab 80 mg Q2W had the lowest cost for PASI 100.In this analysis, ixekizumab is the most cost-efficient biologic in the US when targeting complete resolution, as measured by PASI 100 in PsO.

To quantify healthcare costs in patients with psoriasis overall and in psoriasis patient sub-groups, by level of disease severity, presence or absence of psoriatic arthritis, or use of biologics.Administrative data from Truven Health Analytics MarketScan Research Database were used to select adult patients with psoriasis from January 2009 to January 2014. The first psoriasis diagnosis was set as the index date. Patients were required to have ≥6 months of continuous enrollment with medical and pharmacy benefits pre-index and ≥12 months post-index. Patients were followed from index until the earliest of loss to follow-up or study end. All-cause healthcare costs and outpatient pharmacy costs were calculated for the overall psoriasis cohort and for the six different psoriasis patient sub-groups: (a) patients with moderate-to-severe disease and mild disease, (b) patients with psoriatic arthritis and those without, and (c) patients on biologics and those who are not. Costs are presented per-patient-per-year (PPPY) and by years 1, 2, 3, 4, and 5 of follow-up, expressed in 2014 US dollars.A total of 108,790 psoriasis patients were selected, with a mean age of 46.0 years (52.7% females). Average follow-up was 962 days. All-cause healthcare costs were $12,523 PPPY. Outpatient pharmacy costs accounted for 38.6% of total costs. All-cause healthcare costs were highest for patients on biologics ($29,832), then for patients with psoriatic arthritis ($23,427) and those with moderate-to-severe disease ($21,481). Overall, all-cause healthcare costs and outpatient pharmacy costs presented an upward trend over a 5-year period.Psoriasis is associated with significant economic burden, which increases over time as the disease progresses. Patients with moderate-to-severe psoriasis, those with psoriatic arthritis, or use of biologics contributes to higher healthcare costs. Psoriasis-related pharmacy expenditure is the largest driver of healthcare costs in patients with psoriasis.

Log data is a valuable resource for failure prediction and troubleshooting in large-scale systems. However, with the rapid growth of the system scale and the popularity of various applications in productional environments, the volume of logs emerged per day becomes huge, posing serious challenges for storage and analysis. To solve these problems, we propose an online log filtering mechanism to eliminate the redundant and noisy log records through event filtering and instance filtering, aiming to minimize the log size without losing important information required for the fault diagnosis. Our proposed log filtering is evaluated on a real log data derived from a productional cloud computing system, observing that over 76% of the storage space are saved without losing important information.

Summary Background Early identification of responsiveness to biologic treatments in psoriasis has significant clinical and economic implications. Objectives To evaluate whether early clinical improvements in Psoriasis Area and Severity Index (PASI) scores could predict subsequent clinical responses in patients treated with ixekizumab, an anti-interleukin-17 monoclonal antibody. Methods This post hoc analysis was derived from a phase II study in patients with moderate-to-severe plaque psoriasis (n = 114) who received multiple doses of ixekizumab 10, 25, 75 or 150 mg subcutaneously over 20 weeks. PASI score improvements from baseline to weeks 2, 4 and 6 were evaluated to determine the optimal threshold for predicting subsequent PASI responses at week 12. Results Early clinical improvement in disease symptoms at weeks 4 and 6 was predictive of ≥ 75% improvement in PASI score (PASI 75) at week 12 with ≥ 90% predictability. A 40–50% improvement in PASI (PASI 40 to PASI 50) from baseline to weeks 4 and 6 was the optimum range for predicting PASI 75 response at week 12. For all doses combined, achieving PASI 40 at week 4 or week 6 was associated with high negative predictive values (NPVs) (80% and 95%, respectively) and positive predictive values (PPVs) (89% and 84%, respectively). For all doses combined, achieving PASI 50 at week 4 or week 6 was associated with NPVs of 71% and 89% and PPVs of 94% and 89%, respectively. Sensitivity analysis with the high-dose group (75 and 150 mg) results confirmed these findings. Conclusions Early clinical responses (and nonresponse) may help predict later clinical responses in patients treated with ixekizumab.

Patients with moderate-to-severe psoriasis report impaired health-related quality of life (HRQoL).To assess speed of onset of ixekizumab-induced clinically relevant improvement in HRQoL.This post hoc analysis used pooled data from patients randomized in UNCOVER-2 and UNCOVER-3, and treated with 80 mg ixekizumab every 2 weeks (IXEQ2W), 80 mg ixekizumab every 4 weeks (IXEQ4W), 50 mg etanercept (ETN) twice weekly or placebo (PBO) for 12 weeks. HRQoL and pruritus were assessed using the Dermatology Life Quality Index (DLQI) and Itch Numeric Rating Scale (NRS), respectively. Minimally clinical important differences (MCID) in DLQI and Itch NRS were defined as ≥5-point and ≥4-point improvements from baseline, respectively. Time to response from randomization was estimated using Kaplan-Meier methodology and the log-rank test. Hazard ratios between treatments were calculated using a Cox proportional hazards regression model adjusting for studies.A total of 2570 patients were included: 361 PBO; 740 ETN; 733 IXEQ4W and 736 IXEQ2W. Significantly greater differences in time to DLQI ≥5 point or Itch NRS ≥4 point improvement for IXEQ2W or IXEQ4W compared with ETN and PBO (P 0.001) were observed. The median time when 50% of patients reached a ≥5-point reduction in DLQI was shorter for ixekizumab-treated patients (2 weeks, both schedules) compared with ETN- (4 weeks) or PBO-treated (12 weeks) patients. Likewise, the median time when 50% of patients reached a ≥4-point reduction in Itch NRS was shorter for ixekizumab-treated patients (2 weeks, both schedules) compared with ETN- (8 weeks) or PBO-treated (12 weeks) patients. Significantly more ixekizumab-treated patients were likely to achieve MCIDs in DLQI or itch reduction compared with ETN or PBO after 12 weeks of treatment.Ixekizumab-treated patients achieved more rapid improvements both in HRQoL and itch compared with patients treated with ETN and PBO.

Statins have been shown to impact international normalized ratio (INR) when coadministered with warfarin. The aim of this study was to assess the effect of pitavastatin compared with rosuvastatin on steady-state pharmacodynamics (PD) of warfarin by measuring INR in healthy adult subjects.Subjects received oral doses of warfarin 5 mg once daily on days 1 through 3. The dose was titrated on days 4 through 9 to reach a steady-state INR of 1.5 to 2.2. Warfarin was continued on days 10 through 21 and pitavastatin 4 mg or rosuvastatin 40 mg was administered once daily on days 14 through 22. After a 14-day washout period, the process was repeated with the alternate statin. STUDY NUMBER: NK-104-4.03US.For pitavastatin, mean INR changed from 1.73 ± 0.18 (n = 42) on day 14 before starting statin dosing, to 1.78 ± 0.29 (n = 42) on day 22 at treatment end; the difference in INR was not significant (p = 0.219). For rosuvastatin, mean INR increased significantly from 1.74 ± 0.20 (n = 43) at baseline to 1.90 ± 0.30 (n = 43) at treatment end (p 0.001). Rosuvastatin caused a significantly greater increase in INR than pitavastatin (p 0.001).Steady-state INR during warfarin treatment did not change significantly when pitavastatin 4 mg was added to the regimen, while a significant increase was observed when rosuvastatin 40 mg was added. The effect of rosuvastatin on INR was significantly larger than the effect of pitavastatin. This study is limited because it was done in healthy volunteers. Further studies in patient populations are needed to better understand the clinical significance of the results.

Background Platelet inhibition is critical in reducing both short- and long-term atherothrombotic risks after acute myocardial infarction (MI), especially among patients managed with percutaneous coronary intervention (PCI). Currently available antiplatelet medications, including adenosine diphosphate (ADP) receptor inhibitors, have demonstrated variability in efficacy and safety in clinical trials, yet few studies have examined contemporary "real-world" approaches to platelet inhibition and associated outcomes. Methods TRANSLATE-ACS is a prospective observational study that will track up to 17,000 MI patients managed with PCI, from the inhospital to outpatient settings for up to 12 months postdischarge to provide a comprehensive picture of current treatment patterns and outcomes in routine clinical practice. TRANSLATE-ACS exemplifies a collaborative study design that efficiently builds upon a well-established PCI registry platform, and yet, through a systematic telephone interview follow-up process, provides important longitudinal clinical and economic follow-up capacity through 15 months after initial MI hospitalization. Furthermore, TRANSLATE-ACS incorporates a hospital-level, clustered, randomized substudy to investigate the impact of point-of-care platelet inhibition testing on subsequent patient management. Finally, TRANSLATE-ACS provides feedback through quarterly reports to participating sites on their care practices benchmarked to peer performance to support and promote longitudinal quality of cardiovascular care delivery. Conclusion TRANSLATE-ACS not only addresses important clinical and scientific questions but also includes pioneering design features that will assist in the evolution of clinical registries.

The purpose of this analysis was to determine the time by which a prasugrel 60-mg loading dose (LD) achieved significantly greater inhibition of platelet aggregation (IPA) than the peak IPA after a clopidogrel 300-mg LD or 600-mg LD. Data were pooled from nine studies representing 587 individuals: 274 healthy subjects and 313 patients with stable coronary artery disease. The primary pharmacodynamic measure was IPA using 20 mu M adenosine-5`-diphosphate as the agonist. Gatekeeping analysis compared the peak IPA at 4, 6, and 24 hours after a clopidogrel 300-mg or 600-mg LD with IPA at various prior time points backwards after a prasugrel LD until a statistically nonsignificant difference was reached. Prasugrel 60-mg LD produced greater IPA by 30 minutes than the peak IPA after a clopidogrel 300-mg LD (P < 0.0001). Significantly greater IPA was achieved at 1 hour after prasugrel 60-mg LD compared with the peak IPA after 600-mg clopidogrel LD (P < 0.0001), regardless of sex, body weight, or age and as early as 30 minutes in the diabetic subgroup. A prasugrel 60-mg LD produces significantly faster onset and greater IPA compared with a clopidogrel 300-mg LD or 600-mg LD.

Aims Patients with diabetes mellitus (DM) have increased platelet reactivity and reduced platelet response to clopidogrel compared with patients without DM. Prasugrel, a more potent antiplatelet agent, is associated with greater reductions in ischaemic events compared with clopidogrel, particularly in patients with DM. The aim of this study was to perform serial pharmacodynamic assessments of prasugrel with high-dose clopidogrel in patients with DM. Methods and results Optimizing anti-Platelet Therapy In diabetes MellitUS (OPTIMUS)-3 was a prospective, randomized, double-blind, crossover study in patients with type 2 DM and coronary artery disease (CAD). Patients ( n = 35) were randomly assigned to either prasugrel 60 mg loading dose (LD)/10 mg maintenance dose (MD) or clopidogrel 600 mg LD/150 mg MD over two 1-week treatment periods separated by a 2-week washout period. Platelet function was assessed by Verify Now ® P2Y12 assay, light transmission aggregometry, and vasodilator-stimulated phosphoprotein phosphorylation at 0, 1, 4, and 24 h and 7 days. Greater platelet inhibition by Verify Now ® P2Y12 was achieved by prasugrel compared with clopidogrel at 4 h post-LD (least squares mean, 89.3 vs. 27.7%, P < 0.0001; primary endpoint). The difference in platelet inhibition between prasugrel and clopidogrel was significant from 1 h through 7 days ( P < 0.0001). Similar results were obtained using all other platelet function measures. Prasugrel resulted in fewer poor responders at all time points irrespective of definition used. Conclusion In patients with type 2 DM and CAD, standard-dose prasugrel is associated with greater platelet inhibition and better response profiles during both the loading and maintenance periods when compared with double-dose clopidogrel.

Recent guidelines recommend use of aspirin and either clopidogrel or prasugrel for at least 12 months following use of drug-eluting or bare metal stents in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). This study evaluated factors associated with clopidogrel use and adherence in ACS patients following PCI.The US employer-based MarketScan commercial claims database was used to examine factors associated with clopidogrel use and adherence. Adherence was defined as a medication possession ratio of 80% or higher. Multivariate logistic regression analyses were conducted to identify factors associated with clopidogrel use and adherence and included patient demographics, comorbidities, and prior beta-blocker, statin, and angiotensin converting enzyme inhibitor (BSI) use as factors.A total of 10,465 patients aged 18-65 years who met inclusion criteria were hospitalized for ACS and underwent PCI between 01/01/2005 and 12/31/2006. Overall, the rate of clopidogrel use was 92.8% for ACS-PCI patients and 66.8% of the clopidogrel users were adherent. Receiving PCI without stenting (Odds Ratio [OR] = 3.28), comorbid hypertension (OR = 1.50), diabetes (OR = 1.49), and atrial fibrillation (OR = 1.91) were associated with decreased filled prescriptions for clopidogrel. Younger age (OR = 0.83) and prior use of clopidogrel (OR = 0.54) or other BSI medications (OR = 0.44) were associated with increased use of clopidogrel (all p values 0.05). Factors significantly associated with non-adherence of clopidogrel were prior use of clopidogrel (OR = 1.40), prior hospitalization (OR = 1.34), chronic pulmonary disease (OR = 1.31), PCI without stenting (OR = 1.32), diabetes (OR = 1.17), and younger age (OR = 1.29). Prior use of BSI medications (OR = 0.82) increased adherence to clopidogrel.Prior use of clopidogrel, comorbid conditions such as diabetes and chronic pulmonary disease, prior hospitalization, PCI without stenting, and younger age had a negative impact on clopidogrel adherence. These findings may assist programs to improve thienopyridine compliance through a better understanding of patients' disease profiles and concomitant medication use.

OBJECTIVE To compare adherence and persistence to typical versus atypical antipsychotics and between specific atypical agents in the usual care of schizophrenia and to examine the association between adherence and persistence. METHOD Data were drawn from a 3-year prospective, nonrandomized, noninterventional study of schizophrenia conducted during 1997-2003. Initiators on haloperidol, risperidone, olanzapine, quetiapine, and clozapine with at least 1 year of follow-up were included (n = 878). Adherence (Medication Possession Ratio, MPR) and persistence (time to all-cause medication discontinuation) were assessed using medical record prescription information. Analyses employed multivariate statistics adjusted for group differences. RESULTS Overall, 58% of the patients were deemed adherent (MPR >80%). Adherence rates were higher: for atypical (59.4%) than typical antipsychotics (34.5%, p < 0.001), for clozapine (77%) than each comparator excluding olanzapine (p < 0.01), and for olanzapine (64%) than risperidone (57%, p = 0.027) and quetiapine (52%, p = 0.019). Differences between risperidone and quetiapine were not statistically significant. Adherence and persistence were highly correlated (r = 0.957, p < 0.001). CONCLUSION In the usual care of schizophrenia, medication adherence and persistence appear to be highly correlated and to significantly differ between typical and atypical antipsychotics and among atypical agents. The choice of antipsychotic may play a meaningful role in patients' adherence to and persistence with antipsychotic medications.

Psoriasis is a chronic, incurable, and immune-mediated skin disorder that is characterized by erythematous scaly papules and plaques. Understanding of psoriasis at the molecular level has led to the development of biologic agents that target disease-specific inflammatory mediators in psoriatic lesions. Biologic agents have become important components of the psoriasis armamentarium, but some patients become refractory to these agents over time or fail to respond to subsequent biologics.To (a) evaluate demographic and clinical characteristics of psoriasis patients who have treatment patterns suggestive of failure to a newly initiated biologic agent (treatment-regimen failures) compared with those who do not (non-treatment-regimen failures) and (b) to assess health care-related resource utilization and costs in non-treatment-regimen failures and treatment-regimen failures.In this retrospective observational cohort study, patients were selected from the MarketScan claims database of commercially insured individuals and individuals with Medicare supplemental insurance. The index event was a newly initiated biologic agent for the treatment of psoriasis (etanercept, adalimumab, ustekinumab, or infliximab) between January 2010 and December 2011. The analysis included psoriasis patients aged ≥ 18 years with ≥ 1 prescription claim for a biologic and continuous enrollment 12 months pre- and post-index date. Patients with claims for a biologic in the pre-index period were excluded. Patients were divided into treatment-regimen-failure and non-treatment-regimen-failure groups based on their treatment patterns post-index date. The treatment-regimen-failure group included patients who switched to another biologic, discontinued the biologic without restarting, increased the dose of the biologic, or augmented treatment with a nontopical psoriasis medication during the post-index period. Between-group patient characteristics and medication use were compared using analysis of variance for continuous variables and chi-square tests for categorical variables without adjustment. Cost differences were compared using the propensity score-adjusted bin bootstrapping method.Overall, 2,146 patients met the enrollment criteria. The mean age was 45.1 years. Of these patients, 41.5% were considered treatment-regimen failures. Among treatment-regimen failures, 53% were females, and among non-treatment-regimen failures, 61% were male. Patients who experienced treatment-regimen failure had higher incidences of comorbid cerebrovascular disease, hypertension, chronic pulmonary disease, depression, and anxiety in the pre-index period and were more likely to use concomitant topicals (67.0% vs. 58.4%; P0.001), methotrexate (20.2% vs. 7.3%; P0.001), and cyclosporine (3.1% vs. 1.0%; P0.001) in the post-index period. Mean total all-cause health care costs were higher in patients with treatment-regimen failure versus non-treatment-regimen failure during the pre-index period ($8,024 vs. $6,637; P = 0.002), but patients with non-treatment-regimen failure had higher all-cause costs ($30,759 vs. $28,012; P = 0.002) and psoriasis-related costs ($25,286 vs. $19,625; P0.001) during the post-index period.The results of the current study demonstrated that psoriasis patients with treatment patterns suggestive of treatment-regimen failure on an index biologic had different characteristics and incurred higher all-cause health care costs than did patients without treatment-regimen failure during the pre-index period.

Background: Itch is a prevalent symptom of psoriasis that impacts quality of life. Objective: We sought to describe improvements in itch severity, skin pain, and bothersomeness of skin appearance caused by psoriasis among patients who received ixekizumab, etanercept, or placebo in three 12 -week, phase III clinical trials (UNCOVER -1, -2, and -3). Methods: The itch numeric rating scale evaluated psoriasis itch severity in all 3 trials. Skin pain was assessed by skin pain visual analog scale. Bothersomeness because of redness/discoloration, thickness, and scaling/flaking was assessed with the Psoriasis Skin Appearance Bothersomeness instrument. Psoriasis skin appearance bothersomeness and skin pain were assessed at baseline and week 12; itch numeric rating scale score was assessed at baseline and weeks 1, 2, 4, 8, and 12. Results: Patients who received ixekizumab demonstrated statistically significant improvements (P

Objective: This prospective observational study compared the 3-year clinical and functional course of schizophrenia among individuals with and without diabetes at study entry. Method: Data were drawn from a large, 3-year, multisite, prospective, naturalistic study of treatment for schizophrenia-related disorders. The study was conducted in the United States between July 1997 and September 2003 and represented treatment practices in diverse systems of care. Participants were diagnosed with schizophrenia or schizoaffective or schizophreniform disorders based on DSM-IV criteria. Clinical and functional outcomes were assessed at study enrollment and at 12-month intervals using standard psychiatric measures, medical records, and a validated patient-reported questionnaire. Diabetes status was determined by participant interview at enrollment. Statistical analyses used mixed models with repeated measures. Results: Of 594 participants queried about comorbid medical conditions at enrollment, 76 (12.8%) reported having diabetes. Other comor-bid conditions were reported by 79% of the diabetes group (N = 60) and 50% of the nondiabetes group (N = 259). Across the 3-year study, participants with diabetes differed significantly from participants without diabetes on 2 of 36 outcome measures: more contacts with nonpsychiatrist physicians (p < .001) and poorer physical health (p = .015). Groups did not differ significantly on mental health symptomatology, mental health resource utilization, legal and safety issues, substance use, productivity, activities and relationships, or quality of life. Conclusions: In this 3-year, prospective, naturalistic study, the course of schizophrenia did not differ significantly between participants with and without diabetes, although persons with diabetes did have poorer physical health and more contacts with nonpsychiatrist physicians. Findings highlight the need for better medical treatment for people with schizophrenia, both with and without comorbid diabetes.

To prospectively measure the link between depressive symptoms and functional outcomes in the long-term treatment of people with schizophrenia.Data were drawn from a large, multi-site, 3-year, prospective, naturalistic, observational study, in which subjects with schizophrenia were assessed at enrollment and at 12-month intervals thereafter. Individuals who were "Depressed" (defined as a total scoreor =16 on the Montgomery-Asberg Depression Rating Scale) at enrollment were compared to those "Non-depressed" on functional outcomes, using self-report measures, clinicians' ratings, and information from medical records. Statistical analyses included Generalized Estimation Equation and mixed regression analyses adjusted for individual characteristics. Longitudinal group comparisons across the 3-year study were augmented with a cross-sectional group comparison at enrollment.At enrollment, 39.4% (877/2228) of the participants were deemed Depressed. Across the 3-year study, the depressed cohort was significantly more likely than the Non-depressed to use relapse-related mental health services (emergency psychiatric services, sessions with psychiatrists); to be a safety concern (violent, arrested, victimized, suicidal); to have greater substance-related problems; and to report poorer life satisfaction, quality of life, mental functioning, family relationships, and medication adherence. Furthermore, changes in depressed status were associated with changes in functional outcomes.People with schizophrenia and concurrent depressive symptoms have poorer long-term functional outcomes compared to the Non-depressed. Their poorer quality of life, greater use of mental health services, and higher risk of involvement with law enforcement agencies underscore a need for special treatment interventions. Treatment of the non-psychotic dimensions of schizophrenia is a critical part of recovery.

Background: Relatively little is known about the relationships between medication adherence and long-term functional outcomes in the treatment of schizophrenia. To extend previous research, we prospectively examined the relationships between adherence with any antipsychotic medication and functional outcomes among schizophrenia patients treated over a 3-year period, assessed the stability of adherence over time, and examined whether adherence in the first year predicts changes in functional outcomes over the following 2 years. Method: Analyses included 1906 participants with DSM-IV diagnoses of schizophrenia or schizoaffective or schizophreniform disorder in a multi-site, 3-year, prospective, naturalistic study conducted in the United States between July 1997 and September 2003. Outcome measures were assessed at 6-month intervals using systematic medical record abstraction and structured interview of patients. Adherence with antipsychotic regimen was assessed using patient-reported adherence and the medication possession ratio (percent days with prescription for any antipsychotic), dichotomized into adherence and nonadherence. Analyses employed generalized estimating equations and mixed models with repeated measures. Results: Nonadherence was associated with poorer functional outcomes, including greater risks of psychiatric hospitalizations, use of emergency psychiatric services, arrests, violence, victimizations, poorer mental functioning, poorer life satisfaction, greater substance use, and more alcohol-related problems (all p
