Frequency and predictors of a high clinical response in patients with psoriasis on biological therapy in daily practice: results from the prospective, multicenter BioCAPTURE cohort.

BACKGROUND: It is important to assess which patients with psoriasis are more likely to achieve high clinical responses on biologics. OBJECTIVES: To assess the number of treatment episodes (TEs) that achieve a 100% improvement in Psoriasis Area and Severity Index (PASI 100), PASI 90 or PASI ≤ 5 at week 24 of biological treatment, and which baseline patient characteristics predict treatment response. METHODS: Data from patients with psoriasis treated with adalimumab, etanercept, infliximab or ustekinumab were extracted from a prospective cohort. TEs with high clinical responses were described. Uni- and multivariate regression analyses were performed with the generalized estimating equation method to elucidate which baseline patient characteristics were predictors for PASI 90 and PASI ≤ 5 at week 24. RESULTS: In total, 454 TEs were extracted (159 adalimumab; 193 etanercept; 19 infliximab; 83 ustekinumab) from 326 patients. At week 24, in 3%, 15% and 59% of TEs, respectively, PASI 100, PASI 90 and PASI ≤ 5 was reached. In TEs without a PASI 100 or PASI 90 response, PASI ≤ 5 was still achieved in 58% and 52%, respectively. Baseline PASI ≥ 10 was a strong predictor for achieving PASI 90; baseline PASI < 10 and a lower baseline body mass index (BMI) were significant predictors for PASI ≤ 5 at week 24. CONCLUSIONS: A limited number of patients achieved PASI 100 or PASI 90 at 24 weeks of biological treatment. Including an absolute PASI score in the assessment of psoriasis severity is important. Baseline BMI was an important, modifiable predictor for a high response.

Comparison of the 1- and 5-year effectiveness of adalimumab, etanercept and ustekinumab in patients with psoriasis in daily clinical practice: results from the prospective BioCAPTURE registry.

BACKGROUND: The efficacy of etanercept and ustekinumab in psoriasis has been compared in one randomized controlled trial. Comparison of the long-term effectiveness of biologics in daily-practice psoriasis treatment is currently lacking. OBJECTIVES: To compare the effectiveness between the three widely used outpatient biologics adalimumab, etanercept and ustekinumab in daily-practice psoriasis treatment and to correct for confounders. METHODS: Data were extracted from the prospective, multicentre BioCAPTURE registry. Multilevel linear regression analyses (MLRAs) and generalized estimating equation (GEE) analyses were performed on the course of mean Psoriasis Area and Severity Index (PASI) and PASI 75 (≥ 75% reduction vs. baseline). Both models were corrected for confounders. Subgroup analyses for biological dose were performed. RESULTS: We included 356 patients with 513 treatment episodes: 178 adalimumab, 245 etanercept and 90 ustekinumab. MLRA showed a similar effectiveness between adalimumab, etanercept and ustekinumab after 1 year, but the highest effectiveness for ustekinumab during 5 years of treatment (P = 0·047; ustekinumab vs. etanercept, P = 0·019). GEE analysis revealed a higher chance of attaining PASI 75 with adalimumab and ustekinumab than with etanercept at 1 year of treatment. A higher than label dose was more often used in patients treated with etanercept (adalimumab, etanercept and ustekinumab: respectively 31·5%, 55·1% and 17% after 1 year, P < 0·001; 39·3%, 71·4% and 24% after 5 years, P < 0·001). CONCLUSIONS: Compared with etanercept, ustekinumab had the highest effectiveness during 5 years of treatment. Patients receiving adalimumab and ustekinumab more often reached PASI 75 than those on etanercept at 1 year of treatment. Dose escalation was more frequent in etanercept and adalimumab than in ustekinumab.

Polymorphisms in CD84, IL12B and TNFAIP3 are associated with response to biologics in patients with psoriasis.

BACKGROUND: The effectiveness of biologics for psoriasis shows heterogeneity among patients. With pharmacogenetic markers, it might be possible to predict treatment response. OBJECTIVES: We aimed to test the association between genetic markers and the response to biologics in psoriasis (etanercept, adalimumab, ustekinumab) in a prospective cohort. METHODS: We investigated the copy number variation in the LCE3B and LCE3C genes, and eight single-nucleotide polymorphisms (SNPs) in HLA-C*06, CD84, IL12B, IL23R, TRAF3IP2, ERAP1, IFIH1 and TNFAIP3. The decrease in Psoriasis Area and Severity Index (PASI) was calculated as ∆PASI (absolute PASI decrease compared with baseline) and PASI 75 (proportion of patients with ≥ 75% improvement vs. baseline). Associations between genetic variants and treatment outcome were assessed using multivariable linear regression analysis (∆PASI corrected for baseline PASI, primary analysis) and Pearson's χ2 -test or Fisher's exact test (PASI 75, secondary analysis). RESULTS: We included 348 treatment episodes in 234 patients. Patients heterozygous (GA) for the SNP in CD84 (rs6427528) had a better ∆PASI response to etanercept after 3 months (P = 0·025) than the homozygous reference group (GG). In addition, patients heterozygous (CT) for the IL12B variant showed a better response (∆PASI) to ustekinumab (P = 0·017) than the reference group (CC). Patients homozygous (GG) for the SNP in TNFAIP3 showed a worse response (∆PASI) to ustekinumab (P = 0·031) than the reference group (TT). The associations with ustekinumab resulting from the primary analysis were not confirmed in the secondary (PASI 75) analysis. CONCLUSIONS: We demonstrated a strong association between etanercept use in psoriasis and variations in CD84, a gene that was previously found to be a predictor of response to etanercept in rheumatoid arthritis.

Body mass index predicts discontinuation due to ineffectiveness and female sex predicts discontinuation due to side-effects in patients with psoriasis treated with adalimumab, etanercept or ustekinumab in daily practice: a prospective, comparative, long-term drug-survival study from the BioCAPTURE registry.

BACKGROUND: Predictors for successful treatment are important for personalized medicine. Predictors for drug survival of biologics in psoriasis have been assessed, but not split for different biologics or for the reason of discontinuation. OBJECTIVES: To compare long-term drug survival between the outpatient biologics adalimumab, etanercept and ustekinumab in patients with psoriasis, and to elucidate predictors for overall survival and drug discontinuation due to ineffectiveness and side-effects for each biologic separately. METHODS: Ten years of data were extracted from the prospective, multicentre, long-term BioCAPTURE registry. Kaplan-Meier survival analyses and confounder-corrected multivariate Cox regression analysis for drug survival (MCR-DS) were performed to compare drug survival between biologics. To elucidate the predictors for different reasons of discontinuation for each biologic, univariate Cox regression analyses and multivariate Cox regression analyses for predictors (MCR-P) with backward selection were performed. RESULTS: In total, 526 treatment episodes - 186 adalimumab, 238 etanercept and 102 ustekinumab - were included covering 1333 treatment years. MCR-DS showed a significantly higher overall survival for ustekinumab compared with adalimumab and etanercept. MCR-P showed that higher body mass index (BMI) was a predictor for discontinuation due to ineffectiveness for etanercept and ustekinumab and that female sex was a predictor for discontinuation due to side-effects for adalimumab, etanercept and ustekinumab. CONCLUSIONS: Ustekinumab has the highest confounder-corrected long-term drug survival in psoriasis treatment, compared with adalimumab and etanercept. Higher BMI is a predictor for discontinuation due to ineffectiveness in etanercept and ustekinumab, and female sex is a consistent predictor for discontinuation due to side-effects in all three outpatient biologics.

Predictors of adalimumab drug survival in psoriasis differ by reason for discontinuation: long-term results from the Bio-CAPTURE registry.

BACKGROUND: Drug survival is an indicator for treatment success; insight in predictors associated with drug survival is important. OBJECTIVES (I): To analyse the long-term drug survival for adalimumab in patients with psoriasis treated in daily practice and (II) to identify predictors of prolonged drug survival for adalimumab split for different reasons of discontinuation. METHODS: Data were extracted from a prospective psoriasis cohort and analysed using Kaplan-Meier survival curves split for reasons of discontinuation. Baseline predictors associated with longer drug survival were identified using multivariate Cox-regression analysis. RESULTS: One hundred and sixteen patients were included with a total of 208 patient-years. Overall drug survival was 76% after 1 year and 52% after 4.5 years. In patients who stopped due to ineffectiveness, longer drug survival was associated with the absence of specific comorbidities (P = 0.03). In patients who stopped due to side-effects, longer drug survival was associated with male gender (P = 0.02). CONCLUSIONS: Predictors of adalimumab drug survival in psoriasis differ by reason for discontinuation. Strong, specific predictors can lead to patient-tailored treatment.

Comparing treatment goals for psoriasis with treatment decisions in daily practice: results from a prospective cohort of patients with psoriasis treated with biologics: BioCAPTURE.

BACKGROUND: Treatment goals have been developed to optimize daily clinical practice psoriasis care, but have not yet been studied in real life. OBJECTIVES: To investigate to what extent treatment decisions made by dermatologists in daily clinical practice for patients with psoriasis on biologics are already in accordance with treatment goals without the active application of the treatment goals algorithm. METHODS: Data were extracted from a prospective daily practice cohort of patients with psoriasis on biologics. Analysis was done on effectiveness (Psoriasis Area and Severity Index score) and quality of life (Dermatology Life Quality Index questionnaire). Treatment decisions such as dosage adjustments, combination treatments, or switching therapy were compared with the treatment goals algorithm. RESULTS: In 64% (253 of 395) of visits, physicians followed the treatment goals algorithm. There were 162 (41%) visits in which there should have been a treatment modification according to treatment goals (group Modify) and a modification was indeed made in 59 of these 162 visits (36%). In 233 (59%) visits no treatment modification was necessary (group Continue) and therapy was indeed not modified in 194 of 233 visits (83%). CONCLUSIONS: Physicians acted in accordance with treatment goals in the majority of patient visits. In the patient group not achieving these goals, physicians should have modified therapy according to treatment goals but continued the same therapeutic regimen in the majority of visits. Optimizing therapy and defining barriers in the latter group might increase treatment results in daily practice psoriasis care.

'Happy' drug survival of adalimumab, etanercept and ustekinumab in psoriasis in daily practice care: results from the BioCAPTURE network.

BACKGROUND: Drug survival is a marker for treatment success. To date, no analyses relating dermatological quality-of-life measures to drug survival have been published. OBJECTIVES: (i) To describe 1-year drug survival for adalimumab, etanercept and ustekinumab in a daily practice psoriasis cohort, and (ii) to introduce the concept of 'happy' drug survival, defined as Dermatology Life Quality Index (DLQI) ≤ 5 combined with being 'on drug' at a specific time point. METHODS: Data were extracted from a prospective registry. Drug survival was analysed using Kaplan-Meier estimates. 'Happy' drug survival was calculated, with data split into 'happy' (DLQI ≤ 5) vs. 'unhappy' (DLQI > 5) at baseline and months 3, 6, 9 and 12. RESULTS: 249 treatment episodes were included (101 adalimumab, 82 etanercept, 66 ustekinumab). The 1-year drug survival rates for ustekinumab, adalimumab and etanercept were 85%, 74% and 68%, respectively. Ustekinumab showed a better confounder-corrected drug survival vs. etanercept [hazard ratio (HR) 3·8, P = 0·02] and a trend towards better survival vs. adalimumab (HR 2·3, P = 0·1). At baseline, the majority (n = 115, 73%) was considered 'unhappy' and a minority 'happy' (n = 42, 27%) (ratio 'happy':'unhappy' was 1 : 2.7). The percentage of treatment episodes with 'happy' on-drug patients increased to 79% after 1 year. CONCLUSIONS: Ustekinumab showed a better overall drug survival than etanercept, and a trend towards a better overall drug survival than adalimumab. After 1 year, patients reported to be 'happy' in 79% of episodes and 'unhappy' in 21%. We introduced the new concept of 'happy' drug survival because the proportion of on-drug patients with good quality of life is an important indicator for treatment success.

Satisfaction of treatment with biologics is high in psoriasis: results from the Bio-CAPTURE network.

BACKGROUND: Although the effectiveness of biologics for psoriasis has been measured extensively with objective outcome measures, studies based on subjective, patient-reported outcome measures remain scarce. OBJECTIVES: To investigate satisfaction with medication, as measured by the Treatment Satisfaction Questionnaire for Medication (TSQM) for biologics in daily practice psoriasis care in the first 6 months of treatment; and to identify possible differences in satisfaction with medication between patients experienced (biologics-experienced) and inexperienced (biologics-inexperienced) in the use of biologics. METHODS: TSQM baseline measurements were compared using measurements taken after 6 months, using the Wilcoxon signed-rank test for paired comparisons. Intention-to-treat with last observation carried forward (ITT with LOCF) and as-treated analyses were performed. The difference between biologics-experienced and biologics-inexperienced patients for TSQM was analysed using ITT with LOCF. At 6 months, outcomes for biologics-experienced and biologics-inexperienced patients were compared using the Mann-Whitney U-test. RESULTS: One hundred and six patients were eligible for analysis, and treated with etanercept (n = 34), adalimumab (n = 49) or ustekinumab (n = 23). Fifty-four per cent of patients were biologics-inexperienced. A statistically significant improvement was seen in all domains of the TSQM ('effectiveness', 'side-effects', 'convenience' and 'global satisfaction') by comparison of months 3 or 6 with baseline (all P ≤ 0·02). After 6 months, biologics-inexperienced patients scored better on the 'global satisfaction' domain than biologics-experienced patients (P < 0·01). CONCLUSIONS: We provide a prospective, longitudinal analysis of TSQM for biologics in daily practice psoriasis care. High satisfaction rates were achieved. The 'effectiveness' and 'convenience' domains showed the most room for improvement.

Propranolol in a case series of 174 patients with complicated infantile haemangioma: indications, safety and future directions.

BACKGROUND: Infantile haemangioma (IH) is a benign, common and self-limiting tumour of infancy; only a minority of cases need active treatment. Currently, propranolol appears superior to classic treatments. OBJECTIVES: To document in a prospective study indications and side-effects of propranolol for complicated IH in a large patient group. METHODS: Analysis of prospectively collected data was performed on 174 patients with IH treated with propranolol in a tertiary referral centre from September 2008 to January 2012. RESULTS: The group consisted of children with a potentially threatening and/or complicated IH; the girl/boy ratio was 123/51, and the mean age at the start of treatment was 4·8 months. In 173 cases (99·4%), treatment was successful, as assessed nonquantitatively by clinical observation. This striking effect was characterized by immediate cessation of growth, softening, fading of the erythema and rapid induction of regression. The mean duration of treatment was 10·7 months. The most important adverse effects were hypotension (3·4%), wheezing (9·2%), nocturnal restlessness (22·4%) and cold extremities (36·2%). In one patient, propranolol was stopped. In 15 patients it was necessary to reduce the dose, although the lower dose was still effective. CONCLUSIONS: In this study, propranolol was effective and safe in almost all patients with complex IH. Administration of systemic medication to an infant with a benign condition requires careful consideration, as only a minority of patients with IH require an active medical intervention. A shift of the indication of propranolol for IH is evident, expanding its application for life-threatening situations or severe functional impairment to early prevention of disfigurement or cosmetically permanent sequelae. However, the indication for such an active approach should be determined by experienced physicians.
