Economic and comorbidity burden among moderate-to-severe psoriasis patients with comorbid psoriatic arthritis.

ABSTRACT:

Objective

To compare the prevalence of comorbidities, health care utilization, and costs between moderate-to-severe psoriasis (PsO) patients with comorbid psoriatic arthritis (PsA) and matched controls.

Methods

Adults ages 18-64 years with concomitant diagnoses of PsO and PsA (PsO+PsA) were identified in the OptumHealth Reporting and Insights claims database between January 2007 and March 2012. Moderate-to-severe PsO was defined based on the use of at least one systemic or phototherapy during the 12-month study period after the index date (randomly selected date after the first PsO diagnosis). Control patients without PsO and PsA were demographically matched 1:1 with PsO+PsA patients. Multivariate regressions were employed to examine PsO/PsA-related comorbidities, medications, health care utilization, and costs between PsO+PsA patients and controls, adjusting for demographics, index year, insurance type, and non-PsO/PsA-related comorbidities.

Results

Among 1,230 matched pairs of PsO+PsA patients and controls, PsO+PsA patients had significantly more PsO/PsA-related comorbidities, with the top 3 most common in both groups being hypertension (35.8% versus 23.5%), hyperlipidemia (34.6% versus 28.5%), and diabetes mellitus (15.9% versus 10.0%). Compared with controls, PsO+PsA patients had a higher number of distinct prescriptions filled (incidence rate ratio 2.3, P < 0.05); were more likely to have inpatient admissions (odds ratio [OR] 1.6), emergency room visits (OR 1.3), and outpatient visits (OR 62.7) (all P < 0.05); and incurred significantly higher total, pharmacy, and medical costs (adjusted annual cost differences per patient $23,160, $17,696, and $5,077, respectively; all P < 0.01).

Conclusion

Compared with matched PsO- and PsA-free controls, moderate-to-severe PsO patients with comorbid PsA had higher comorbidity and health care utilization and costs.

Project description:ObjectiveTo conduct a cost-effectiveness analysis from the perspective of the Spanish National Health System (NHS) comparing ixekizumab versus secukinumab.DesignA Markov model with a lifetime horizon and monthly cycles was developed based on the York model. Four health states were included: a biological disease-modifying antirheumatic drug (bDMARD) induction period of 12 or 16 weeks, maintenance therapy, best supportive care (BSC) and death. Treatment response was assessed based on both Psoriatic Arthritis Response Criteria (PsARC) and ≥90% improvement in the Psoriasis Area Severity Index score (PASI90). At the end of the induction period, responders transitioned to maintenance therapy. Non-responders and patients who discontinued maintenance therapy transitioned to BSC. Clinical efficacy data were derived from a network meta-analysis. Health utilities were generated by applying a regression analysis to Psoriasis Area Severity Index and Health Assessment Questionnaire‒Disability Index scores collected in the ixekizumab SPIRIT studies. Results were subject to extensive sensitivity and scenario analysis.SettingSpanish NHS.ParticipantsA hypothetical cohort of bDMARD-naïve patients with psoriatic arthritis and concomitant moderate-to-severe psoriasis was modelled.InterventionsIxekizumab and secukinumab.ResultsIxekizumab performed favourably over secukinumab in the base-case analysis, although cost savings and quality-adjusted life-year (QALY) gains were modest. Total costs were €153 901 compared with €156 559 for secukinumab (difference -€2658). Total QALYs were 9.175 vs 9.082 (difference 0.093). Base-case results were most sensitive to the annual bDMARD discontinuation rate and the modification of PsARC and PASI90 response to ixekizumab or secukinumab.ConclusionIxekizumab provided more QALYs at a lower cost than secukinumab, with differences being on a relatively small scale. Sensitivity analysis showed that base-case results were generally robust to changes in most input parameters.Trial registration numberSPIRIT-P1: NCT01695239; Post-results, SPIRIT-P2: NCT02349295; Post-results.

Project description:IntroductionEtanercept (ETN), a highly effective biological agent for the treatment of psoriasis (PSO) and psoriatic arthritis (PsA), is widely used in Spain. However, evidence of its economic impact is limited, indicating the need for a systematic review of the economic assessments conducted on the use of ETN in the treatment of both PSO and PsA in Spain.MethodsA systematic review was carried out in PubMed, Embase, Cochrane Library, Health Technology Assessment reports and not indexed sources up to November 2018. The inclusion criteria were economic evaluations (total and partial) and dose optimization studies published in English or Spanish on the use of ETN to treat PSO and PsA for ETN in Spain.ResultsA total of 402 publications were identified, of which 32 were selected for inclusion in the review; of these 32 publications, 81.3% analyzed PSO (14 full economic evaluations, 5 partial economic evaluations and 7 dose optimization studies) and 18.8% analyzed PsA (1 economic analysis and 5 dose optimization studies). The perspective of the Spanish National Health Service (NHS) was used in 90.0% (n = 18) of the full and partial economic evaluations. The time horizons ranged from 12 weeks to 2 years. Reductions in the Psoriasis Area and Severity Index (PASI) of 50, 75 and 90% (PASI 50, 75 and 90, respectively) were most commonly used as efficacy outcomes in the complete evaluations. The economic impact of ETN ranged from €9110-14,337/PASI 75 at 12 weeks (50 mg/week) to €82,279/PASI 90 at 2 years, depending on the health outcome, time horizon and ETN dose used. Only one study determined the cost of using ETN for the treatment of PSO (€29,430-52,367/QALY for dose 2 × 25 mg/week or 50 mg/week, respectively). Only one partial economic evaluation on PSA was identified (NHS perspective), resulting in an ETN annual cost of €8585/patient-year.ConclusionConsistent evidence on the economic impact of ETN for the treatment of PSO and PSA in Spain is lacking, mainly due to the highly heterogeneous methodology used and the broad range of outcomes found in the economic evaluations published to date.FundingPfizer S.L.U.

Project description:IntroductionSecukinumab, a fully human monoclonal antibody that directly inhibits interleukin-17A, has demonstrated robust efficacy in the treatment of moderate to severe psoriasis (PsO), psoriatic arthritis (PsA) and ankylosing spondylitis (AS), with a rapid onset of action, sustained long-term clinical responses and a consistently favourable safety profile across phase 3 trials. Here, we report the clinical data at enrolment from SERENA, designed to investigate the real-world use of secukinumab across all three indications.MethodsSERENA is an ongoing, longitudinal, observational study conducted at 438 sites across Europe in patients with moderate to severe plaque PsO, active PsA or active AS. Patients should have received at least 16 weeks of secukinumab treatment before enrolment in the study.ResultsOverall 2800 patients were included in the safety set; patients with PsA (N = 541) were older than patients with PsO (N = 1799) and patients with AS (N = 460); patients with PsO had a higher mean body weight than patients with PsA and patients with AS; and patients with PsO and patients with AS were predominantly male. Time since diagnosis was longer in patients with PsO compared with patients with PsA and patients with AS, and about 40% of patients were either current or former smokers. The proportion of obese patients (body mass index ≥ 30 kg/m2) was similar across indications. Patients were treated with secukinumab for a mean duration of 1 year prior to enrolment (range 0.89-1.04). The percentages of patients with prior biologics exposure were 31.5% PsO, 59.7% PsA and 55% AS. The percentages of patients prescribed secukinumab monotherapy were 75% (n = 1349) in PsO, 48.2% (n = 261) in PsA and 48.9% (n = 225) in AS groups.ConclusionBaseline demographics of the study population are consistent with existing literature. This large observational study across all secukinumab indications will provide valuable information on the long-term effectiveness and safety of secukinumab in the real-world setting.
