RESUMEN
BACKGROUND: Psoriasis involving challenging body areas, such as the scalp, face, palmoplantar surfaces, or nails, can be challenging to treat and negatively affects patient outcomes. OBJECTIVE: To assess clear responses and cumulative clinical benefits over 5 years of ixekizumab treatment of moderate-to-severe plaque psoriasis in patients with and without baseline involvement of challenging body areas. METHODS: This post hoc analysis included patients treated with ixekizumab in the UNCOVER-3 trial. We assessed PASI100 responses through the week (W) 264 and cumulative clinical benefits at W264 (calculated as least-squares mean of the percentage of maximum area under the curve for PASI100 and PASI% improvement and expressed as cumulative clearance days). Statistical differences were calculated via ANCOVA. RESULTS: A total of 385 patients were analyzed: 349 with scalp involvement, 152 with facial involvement, 96 with palmoplantar involvement, and 229 with nail involvement. Proportions of patients achieving PASI100 were numerically similar between patients with and without scalp and nail involvement. More patients without facial and palmoplantar involvement achieved PASI100 at W60 (only palmoplantar), W108, W156, W204, and W264 (only palmoplantar). At W264, cumulative clinical benefits for PASI100 and PASI% improvement were high and similar in both patient groups, with and without challenging body areas. A significant difference (P=0.006) was only observed for PASI% improvement between patients with and without nail involvement. CONCLUSION: For most efficacy measures, patients treated with ixekizumab over 5 years achieved similar clear responses and cumulative clinical benefits regardless of baseline involvement of challenging body areas.

BACKGROUND: The content validity (appropriateness and acceptability) of patient-reported outcome (PRO) measures for scalp hair loss, eyebrow loss, eyelash loss, nail damage and eye irritation has been demonstrated in adults with alopecia areata (AA) but not adolescents. OBJECTIVES: To explore the content validity of the suite of AA PRO measures and accompanying photoguides in an adolescent sample. METHODS: Semi-structured, 90-min, combined concept elicitation and cognitive interviews were conducted face-to-face with adolescents who experienced ≥ 50% AA-related scalp hair loss. Transcripts underwent thematic and framework analysis. RESULTS: Eleven adolescents (aged 12-17 years, 55% female, 45% nonwhite) diagnosed with AA for 5·9 years (mean) participated. Participants had 69·6% scalp hair (mean) and current eyebrow (82%) and/or eyelash loss (82%) and/or nail involvement (36%). Adolescents reported scalp, eyebrow and eyelash hair loss as their top three most bothersome signs/symptoms. Despite mostly accepting their AA, impacts related to visible areas of hair loss were prominent. Participants demonstrated good understanding and appropriate use of the PRO measures, and advocated including hair loss percentages alongside descriptive categories in the Scalp Hair Assessment PRO™. Results confirmed treatment success thresholds established with adults: achievement of ≤ 20% scalp hair loss, no/minimal eyebrow and eyelash loss, no/a little nail damage and eye irritation (PRO measure categories 0 or 1). CONCLUSIONS: The Scalp Hair Assessment PRO™, PRO Measure for Eyebrows™, PRO Measure for Eyelashes™, PRO Measure for Nail Appearance™ and PRO Measure for Eye Irritation™ and accompanying photoguides are fit-for-purpose self-reported measures of AA signs/symptoms that are impactful to adolescents 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.

BACKGROUND: The identification of early treatment factors that predict the long-term success of maintenance therapy for psoriasis may help optimize individual therapy. OBJECTIVE: To determine early treatment response rates to ixekizumab and ustekinumab and assess whether early response was associated with stable long-term response to these treatments in patients with moderate-to-severe psoriasis. METHODS: This post hoc subgroup analysis of the IXORA-S study (NCT02561806) measured disease severity using the Psoriasis Area Severity Index (PASI) and determined the percentage of patients treated with ixekizumab or ustekinumab who showed PASI 50 at week 2 or 4 (early response) and assessed whether early response was associated with maintaining complete (PASI 100) or almost complete (PASI 90) skin clearance at 80% of monthly visits during weeks 16−52 of treatment (stable response). Nonresponder imputation was used for missing PASI response status. RESULTS: A numerically higher portion of patients treated with ixekizumab were early responders and were significantly more likely to achieve a stable PASI 90 response (P<.0001) or PASI 100 response (P<.0001) than patients treated with ustekinumab. Patients treated with ixekizumab or ustekinumab who were early responders were more likely to achieve a stable response of PASI 90 or 100 (odds ratio>1). CONCLUSION: In patients with moderate-to-severe psoriasis treated with ixekizumab or ustekinumab, early response was a significant factor in maintaining stable complete or almost complete skin clearance. Therefore, rapid response is a clinically relevant factor to consider when optimizing individual therapeutic strategies. J Drugs Dermatol. 2022;21(2):122-126. doi:10.36849/JDD.6063.

BACKGROUND: There is a paucity of long-term real-world evidence comparing the effectiveness of ixekizumab (IXE) and adalimumab (ADA). We compared real-world treatment patterns of IXE-treated and ADA-treated patients with psoriasis over 24 months in the United States. METHODS: A retrospective observational study was conducted using IBM Watson Health MarketScan® databases. Adult patients with psoriasis having ≥1 claim for IXE or ADA from March 1, 2016 – October 31, 2019 were identified. Inverse probability of treatment weighting (IPTW) was used to address cohort imbalances. Cox proportional hazards models were used to estimate the risks of non-persistence, discontinuation, and switching. Logistic regression was used to estimate odds of high adherence. Persistence, adherence, discontinuation, reinitiation, and dosing and switching rates were also analyzed. RESULTS: The final cohorts comprised 475 IXE users and 3159 ADA users over 24 months. IXE users demonstrated higher adherence (36.3% vs 28.8%; P<0.001) and persistence rates (35.2% vs 28.8%; P=0.004), and a lower discontinuation rate (59.1% vs 65.3%; P=0.007) compared to ADA users. IXE users had a higher likelihood of being treatment-adherent compared to ADA users (OR=1.52, 95% CI: 1.24–1.87), a lower risk of non-persistence (HR=0.84, 95% CI: 0.75–0.95), and a lower risk of discontinuation (HR=0.83, 95% CI: 0.74–0.94), respectively. Switching rates were similar in both groups (31.2% vs 30.0%; P=0.608). CONCLUSION: IXE users had better treatment adherence and persistence, and a lower risk of discontinuation compared to ADA users over 24 months. There was no difference in the risk of switching between IXE and ADA. J Drugs Dermatol. 2022;21(4):399-407. doi:10.36849/JDD.6336.

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.

OBJECTIVE: We describe patient-reported outcomes and quality of life through 5 years of treatment in patients with moderate-to-severe plaque psoriasis in the UNCOVER-1 and -2 studies. METHODS: This analysis included patients who were randomized to ixekizumab every 2 weeks then received ixekizumab every 4 weeks during the maintenance period, and who achieved static physician global assessment (0,1) at week 12, completed week 60, and entered the long-term extension period (weeks 60–264). Outcomes measures included responses in itch numeric rating scale (NRS), skin pain visual analog scale (VAS), and dermatology life quality index (DLQI) (0,1), and mean change from baseline in short form health survey (SF-36) mental (MCS) and physical component summaries (PCS), psoriasis skin appearance bothersomeness (PSAB), and work productivity activity impairment (WPAI). RESULTS: At week 264 in UNCOVER-1 and -2, the observed itch NRS ≥4 responses were 82.4% and 93.1%, respectively, the itch NRS=0 responses were 51.7% and 58.5%, respectively, the skin pain VAS=0 responses were 59.3% and 63.1%, respectively, and the DLQI (0,1) responses were 75.0% and 88.1%, respectively. The observed mean changes from baseline at week 264 in UNCOVER-1 and UNCOVER-2 were 3.4 and 6.5, respectively, for SF-36 MCS, 4.4 and 4.8, respectively, for SF-36 PCS, and -21.3 and -22.0, respectively, for PSAB. WPAI psoriasis item scores improved from baseline in both UNCOVER-1 and -2. CONCLUSION: Ixekizumab provided clinically meaningful and sustained improvements in itch, skin pain, DLQI, PSAB, SF-36 PCS, SF-36 MCS, and WPAI through 5 years of treatment in patients with moderate-to-severe plaque psoriasis.

BACKGROUND/OBJECTIVES: Psoriasis is a chronic, immune-mediated dermatologic disorder with a prevalence among children estimated at 0.1%-0.45%, and a median age of onset at approximately 7-10 years. Pediatric psoriasis is known to have negative impacts on health-related quality of life. Among the most bothersome symptoms, itch has been measured using the Itch Numeric Rating Scale (NRS). This study explored the symptom and impacts of itch with pediatric psoriasis patients and evaluated the content validity of the Itch NRS in children. METHODS: Semi-structured qualitative interviews were conducted among a sample of pediatric patients diagnosed with plaque psoriasis. RESULTS: Concept elicitation interviews were completed with 22 children (ages 7-17 years). When asked about most frequent symptoms, 61% reported itching (n = 14) and 65% reported flaking (n = 15). The majority reported itching as bothersome; about half described impacts on their regular activities. Cognitive interviews were completed with 25 children (ages 8-17 years). Most reported that independently completing the Itch NRS would be easy, and all described the meaning of the response options similar to the intended value. Overall, the Itch NRS was received favorably, with comments that the scale was easy or relevant to their experience with psoriasis. CONCLUSIONS: This qualitative study supports the content validity of the Itch NRS for use in a pediatric psoriasis population aged 8-17. Given the established importance of itch to pediatric psoriasis patients, future research exploring the impact of itch on the lives of pediatric psoriasis patients may provide a valuable contribution to the field.

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.

BACKGROUND: Real-world data on treatment patterns associated with use of interleukin-17A inhibitors in psoriasis are lacking. OBJECTIVE: To compare treatment patterns between ixekizumab or secukinumab users in clinical practice. METHODS: 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. RESULTS: 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. LIMITATIONS: Disease severity and clinical outcomes were unavailable. CONCLUSION: 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.

PURPOSE: To assess improvements in health-related quality of life (HRQoL) with ixekizumab treatment in patients with moderate-to-severe psoriasis. METHODS: 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. RESULTS: 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. CONCLUSIONS: Ixekizumab-treated patients reported statistically significant improvements in HRQoL at 12 weeks that persisted through 1 year.

Ixekizumab was efficacious in treating moderate-to-severe genital psoriasis over 12 weeks. We evaluated the long-term efficacy and safety of ixekizumab for up to 52 weeks. Patients were randomized to 80 mg ixekizumab every 2 weeks or to placebo through Week 12, then received 80 mg open-label ixekizumab every 4 weeks through Week 52. In patients initially randomized to ixekizumab, clear or almost clear genital skin was achieved for 73% of patients at Week 12 and 75% at Week 52. Persistent improvements were also observed for overall psoriasis, genital itch, and the impact of genital psoriasis on the frequency of sexual activity. The safety profile was consistent with studies of ixekizumab in patients with moderate-to-severe plaque psoriasis. Ixekizumab provided rapid and persistent improvements in the signs and symptoms of genital psoriasis for up to 52 weeks of treatment.

BACKGROUND: Having psoriasis in hard-to-treat areas, i.e. the scalp, face, palms, soles, nails, and genitals, respectively, can impair patients' quality of life. We investigated the prevalence of hard-to-treat body locations of psoriasis, and described patients' clinical and demographic characteristics, and quality of life impacts in a population-based cohort. METHODS: We performed a cross-sectional study using a total of 4016 adults (≥18 years) with psoriasis from the Danish Skin Cohort. Groups were compared to patients without involvement of hard-to-treat areas. RESULTS: The most frequently affected hard-to-treat area was the scalp (43.0%), followed by the face (29.9%), nails (24.5%), soles (15.6%), genitals (14.1%), and palms (13.7%), respectively. Higher prevalence was generally seen with increasing psoriasis severity. Among all patients 64.8, 42.4, and 21.9% of patients had involvement of ≥1, ≥2, or ≥ 3 hard-to-treat areas. Those with involvement of certain hard-to-treat areas such as hands, feet, and genitals had clinically relevant DLQI impairments. Having involvement of one hard-to-treat area was significantly associated with other hard-to-treat areas affected even after adjusting for age, sex, and psoriasis severity. CONCLUSION: Psoriasis commonly affects hard-to-treat locations, even in patients with mild disease. For some of these areas, patient-reported disease burden, e.g. as measured by DLQI, is impaired.

INTRODUCTION: Genital psoriasis (GenPs) is common and distressing for patients, but is often not discussed with physicians, and no previous clinical trials have assessed the effects of biologics specifically on GenPs and its associated symptoms. AIM: To report results for novel patient-reported outcomes (PROs) for the assessment of symptoms and the sexual impact of GenPs before and after treatment in the IXORA-Q study. METHODS: IXORA-Q (NCT02718898) was a phase III, randomized, double-blind, placebo-controlled study of ixekizumab (80 mg/2 weeks after 160-mg initial dose) vs placebo for GenPs. Men and women ≥18 years old with moderate-to-severe GenPs and body surface area (BSA) ≥1% were assessed through 12 weeks. MAIN OUTCOME MEASURE: GenPs symptoms were assessed using the 8-item Genital Psoriasis Symptoms Scale (GPSS), Genital Psoriasis Sexual Frequency Questionnaire (GenPs-SFQ), and Genital Psoriasis Sexual Impact Scale (GPSIS) (validation data presented in the supplemental materials), and the Dermatology Life Quality Index (DLQI) item 9. RESULTS: For patients receiving ixekizumab (N = 75) vs placebo (N = 74), statistically significant improvement in GenPs symptoms were seen from week 1 onward (GPSS total and individual items, all P < .005). Sexual activity avoidance owing to GenPs symptoms (GPSIS) decreased significantly with ixekizumab from week 4 onward (all P <.005), whereas impact of sexual activity on GenPs improved significantly with ixekizumab at weeks 2-8 (all P < 0.05). Ixekizumab resulted in significant improvement vs placebo by week 1 onward in limitations on frequency of sexual activity owing to GenPs (GenPs-SFQ item 2). Sexual difficulties caused by skin (DLQI item 9) decreased significantly with ixekizumab from week 2 onward (all P < .001). CLINICAL IMPLICATIONS: Both GenPs symptoms and impact on sexual activity improved rapidly and significantly with ixekizumab vs placebo through 12 weeks in patients with moderate-to-severe GenPs and BSA ≥1%. STRENGTH & LIMITATIONS: To our knowledge, this is the first phase III, randomized, placebo-controlled, double-blinded clinical trial to evaluate the effect of any treatment on the symptoms and sexual impact related to GenPs. The study did not include an active comparator owing to the lack of any well-established treatment for moderate-to-severe GenPs, and the period assessed herein was of relatively short duration. CONCLUSION: These validated PRO measures may aid in future clinical studies of GenPs and in facilitating discussions of GenPs symptoms and their impact between patients and clinicians. Yosipovitch G, Foley P, Ryan C. Ixekizumab improved patient-reported genital psoriasis symptoms and impact of symptoms on sexual activity vs placebo in a randomized, double-blind study.

BACKGROUND: Ixekizumab has demonstrated improvement in patients with moderate-to-severe psoriasis by selectively targeting interleukin-17A, which is a proinflammatory cytokine that is important in the pathogenesis of psoriasis. OBJECTIVE: To report 4-year efficacy and safety results from the open-label extension (OLE) of this phase 2 trial. METHODS: Analysis was by last observation carried forward. Patients received ixekizumab, 120 mg, and then 80 mg subcutaneously once every 4 weeks. RESULTS: Of the patients who completed the randomized placebo-controlled trial, 93% entered the OLE. A 75% reduction in the Psoriasis Area Severity Index score was reported in 82% of patients at week 208 of the OLE. A static Physician's Global Assessment score of 0 or 1 was reported in 64% of patients, and a score of 0 was reported in 45% at week 208. Patients' Dermatology Life Quality Index and Itch Visual Analog Scale scores decreased when compared with baseline. Improvements were observed in other efficacy and health outcome measures. Serious adverse events were observed in 16.7% of patients, and 87% had 1 or more treatment-emergent adverse events. Three patients had serious infections. One patient reported 2 major cardiovascular events. LIMITATIONS: The study was unblinded and lacked a placebo or active comparator. CONCLUSIONS: Efficacy was shown to be maintained for up to 4 years of ixekizumab treatment.

Itching is a prevalent plaque psoriasis symptom. Ixekizumab, an IL-17A antagonist, has demonstrated rapid, significant improvements in itch severity over 12 weeks in Phase III psoriasis trials (UNCOVER-1, UNCOVER-2). We assessed the long-term (through 60 weeks) effect of ixekizumab maintenance therapy (80-mg ixekizumab every 4 weeks [IXEQ4W]) on itch severity, using the Itch Numeric Rating Scale, in psoriasis patients who received ixekizumab, placebo, or etanercept for 12 weeks in the Phase III UNCOVER-3 trial. After 12 weeks, patients either continued or switched to IXEQ4W. Mean improvements in itch severity achieved with 12 weeks of ixekizumab (-4.7 to -5.1) were maintained through 60 weeks with IXEQ4W (-4.9 to -5.0). Patients who initially received placebo or etanercept experienced rapid itch severity improvements after switching to ixekizumab at Week 12 (Week 12, placebo: -0.6; etanercept: -3.8; Week 60, placebo/IXEQ4W: -4.9; etanercept/IXEQ4W: -4.7). Ixekizumab maintenance therapy sustained improvements in itch severity through 60 weeks.

BACKGROUND: Little is known regarding real-world health outcomes data among US psoriasis patients, but electronic health records (EHR) that collect structured data at point-of-care may provide opportunities to investigate real-world health outcomes among psoriasis patients. Our objective was to investigate patient-perceived treatment effectiveness, patterns of medication use (duration, switching, and/or discontinuation), healthcare resource utilization, and medication costs using real-world data from psoriasis patients. METHODS: Data for adults (≥18-years) with a dermatology provider-given diagnosis of psoriasis from 9/2014-9/2015 were obtained from dermatology practices using a widely used US dermatology-specific EHR containing over 500,000 psoriasis patients. Disease severity was captured by static physician's global assessment and body surface area. Patient-perceived treatment effectiveness was assessed by a pre-defined question. Treatment switching and duration were documented. Reasons for discontinuations were assessed using pre-defined selections. Healthcare resource utilization was defined by visit frequency and complexity. RESULTS: From 82,621 patients with psoriasis during the study period, patient-perceived treatment effectiveness was investigated in 2200 patients. The proportion of patients reporting "strongly agree" when asked if their treatment was effective was highest for biologics (73%) and those reporting treatment adherence (55%). In 16,000 patients who received oral systemics and 21,087 patients who received biologics, median treatment duration was longer for those who received biologics (160 vs. 113 days, respectively). Treatment switching was less frequent among patients on systemic monotherapies compared to those on combination therapies. The most common reason for discontinuing biologics was loss of efficacy; the most common reason for discontinuing orals was side effects. In 28,754 patients, higher disease severity was associated with increased healthcare resource utilization (increased visit frequency and complexity). When compared between treatment groups (n = 10,454), healthcare resource utilization was highest for phototherapy. Annual medication costs were higher for biologics ($21,977) than oral systemics ($3413). CONCLUSIONS: Real-world research using a widely implemented dermatology EHR provided valuable insights on patient perceived treatment effectiveness, patterns of medication usage, healthcare resource utilization, and medication costs for psoriasis patients in the US. This study and others utilizing EHRs for real-world research may assist clinical and payer decisions regarding the management of psoriasis.

BACKGROUND: Newer psoriasis treatments can achieve greater levels of efficacy than older systemic therapies; however, current psoriasis costs are substantial. We sought to estimate costs per additional responder associated with ixekizumab and etanercept, versus placebo, using efficacy data from phase 3 clinical trials (UNCOVER-2 and UNCOVER-3). METHODS: In UNCOVER-2/UNCOVER-3, patients received subcutaneous placebo, etanercept 50 mg twice weekly (BIW), or ixekizumab one 80 mg injection every 2 weeks (Q2W) after a 160-mg starting dose. Twelve-week induction-phase Psoriasis Area and Severity Index (PASI) 75, PASI 90, and PASI 100 response rates for ixekizumab, etanercept, and placebo were obtained from pooled data from the overall and United States (US) subgroup intention-to-treat (ITT) populations, and used to calculate numbers needed to treat (NNTs) to achieve one additional PASI 75, PASI 90, or PASI 100 response for ixekizumab Q2W and etanercept BIW versus placebo. Twelve-week drug costs per patient were calculated based on the UNCOVER-2/UNCOVER-3 dosing schedule and wholesale acquisition costs. Mean costs per additional responder for PASI 75, PASI 90, and PASI 100 for each treatment versus placebo were calculated for pooled UN-COVER-2/UNCOVER-3 overall and US subgroup ITT populations. RESULTS: Pooled overall ITT population: costs per additional PASI 75, PASI 90, or PASI 100 responder were US $37,540, US $46,299, or US $80,710 for ixekizumab Q2W and US $57,533, US $120,720, or US $404,695 for etanercept BIW, respectively. US subgroup ITT population: costs per additional PASI 75, PASI 90, or PASI 100 responder were US $38,165, US $49,740, or US $93,536 for ixekizumab Q2W and US $69,580, US $140,881, or US $631,875 for etanercept BIW, respectively. CONCLUSIONS: Twelve-week costs per additional responder were lower for ixekizumab Q2W than for etanercept BIW across all levels of clearance (PASI 75, PASI 90, and PASI 100) in the pooled UNCOVER-2/UNCOVER-3 overall and US subgroup ITT populations.

A large medical and pharmacy claims database was used to evaluate outcomes in daily teriparatide (D-TPD) patients in Japan. 445 patients were identified (April 2008-July 2013) with 6+ months' pre- and 18+ months' post-index observation. D-TPD 20 µg subcutaneous injection is indicated for individuals at high risk of fracture. Descriptive analyses were conducted on clinical fractures, health care utilization, and costs. Adherence was measured by medication possession ratio (MPR) (High MPR > 0.8; 0.5 ≤ Medium MPR ≤ 0.8, Low MPR < 0.5). Adjusted analyses of Lower (Low + Medium) MPR vs. High MPR for fracture incidence and hospital admissions were performed using logistic and Poisson regression models; adjusted cost analyses used propensity bin bootstrapping methods. Baseline characteristics were: mean 74.7 years (standard deviation = 8.9); 90 % female; 20 % 1+ fracture. Post-index, 249 and 196 patients had High and Lower MPR, respectively. Mean incident fractures/1000 patient-years for Lower and High MPR patients were 77.4 and 57.7, respectively. Adjusted fracture risk was greater in Lower MPR patients [logistic odds ratio (OR) = 1.67, 95 % confidence interval 0.791-3.541; Poisson incidence rate ratio (IRR) = 1.505, 0.764-2.966]. Hospital admission risk was significantly greater in Lower than High MPR patients (OR = 1.85, 1.169-2.921; IRR = 1.47, 1.137-1.904). High MPR patients had numerically lower inpatient and total unadjusted costs than Lower MPR patients. Adjusted inpatient costs were significantly less in High MPR patients; outpatient and pharmacy costs were greater. Better adherence to D-TPD revealed a trend towards lower fracture risk, and significant reductions in hospital admissions and costs. The small sample size limited the robustness of these results.

BACKGROUND: Regulatory guidance recommends anchor-based methods for interpretation of treatment effects measured by PRO endpoints. Methodological pros and cons of patient global ratings of change vs. patient global ratings of concept have been discussed but empirical evidence in support of either approach is lacking. This study evaluated the performance of patient global ratings of change and patient global ratings of concept for interpreting patient stability and patient improvement. METHODS: Patient global ratings of change and patient global ratings of concept were included in a psychometric validation study of an osteoporosis-targeted PRO instrument (the OPAQ-PF) to assess its ability to detect change and to derive responder definitions. 144 female osteoporosis patients with (n = 37) or without (n = 107) a recent (within 6 weeks) fragility fracture completed the OPAQ-PF and global items at baseline, 2 weeks (no recent fracture), and 12 weeks (recent fracture) post-baseline. RESULTS: Results differed between the two methods. Recent fracture patients reported more improvement while patients without recent fracture reported more stability on ratings of change than ratings of concept. However, correlations with OPAQ-PF score change were stronger for ratings of concept than ratings of change (both groups). Effect sizes for OPAQ-PF score change increased consistently with level of change in ratings of concept but inconsistently with ratings of change, with the mean AUC for prediction of a one-point change being 0.72 vs. 0.56. CONCLUSIONS: This study provides initial empirical support for methodological and regulatory recommendations to use patient global ratings of concept rather than ratings of change when interpreting change captured by PRO instruments in studies evaluating treatment effects. These findings warrant being confirmed in a purpose-designed larger scale analysis.
