Ustekinumab in psoriatic arthritis: need for studies from real-world evidence

The safety assessment of ustekinumab on psoriasis and psoriatic arthritis: A real-world analysis based on the FDA adverse event reporting system database

OBJECTIVE

To assess safety of ustekinumab (UST) on treatment of patients with psoriasis and psoriatic arthritis (PsA) by analyze UST related adverse drug events (ADEs).

METHODS

Data on ADEs associated with UST on psoriasis and PsA were collected from the fourth quarter of 2009 through the third quarter of 2024 in the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FEARS) database. A variety of signal quantization techniques such as reporting odds ratio (ROR), proportional reporting ratio (PRR), bayesian confidence propagation neural network (BCPNN), and multi-item gamma poisson shrinker (MGPS) are used for analysis.

RESULTS

A total of 67,765 ADE reports with UST on psoriasis and PsA as the primary suspected agent covered 25 system organ classes (SOCs). The three most common ADEs are infections and infestations (n = 9698), general disorders and administration site conditions (n = 6336), and injury, poisoning, and procedural complications (n = 6091). Specifically, reproductive system diseases (n = 262) was identified as unique adverse reactions not mentioned in official drug labels. At the preferred term (PT) level, the most common ADEs were psoriasis exacerbation (n = 3486), lower respiratory tract infection (n = 1302) and latent tuberculosis (n = 121). Strong yet rare signals, including notalgia paraesthetica (n = 3, empirical bayesian geometric mean [EBGM] 154.7) and chronic actinic dermatitis (n = 3, EBGM 101.15), were also detected. Compared to patients with PsA, patients with psoriasis treated with UST exhibit significantly stronger associations with hepatobiliary disorders (n = 955, ROR 2.44, PRR 2.4, information component [IC] 1.26, EBGM 2.4) and neoplasms (n = 3150, ROR 2.61, PRR 2.49, IC 1.31, EBGM 2.49). Spontaneous reports consistently demonstrated higher signal strength for infections and skin disorders compared to healthcare professional (HCP) reports. In contrast, at the PT level, HCP reports tended to emphasize stronger signals for rare or specific conditions.

CONCLUSION

This study highlights a spectrum of UST-associated ADEs covering 25 SOCs in the treatment of patients with psoriasis and PsA, which emphasizes the need for vigilant clinical monitoring, particularly for infections, hepatobiliary disorders, and rare but high-signal events such as notalgia paraesthetica, chronic actinic dermatitis and pure testicular seminoma stage I. Clinicians should combine insights from both spontaneous and HCP reports and pay special attention to infections and reproductive system disorders.

Long-term effectiveness and persistence of ustekinumab and TNF inhibitors in patients with psoriatic arthritis: final 3-year results from the PsABio real-world study

OBJECTIVES

To evaluate real-world persistence and effectiveness of the IL-12/23 inhibitor, ustekinumab or a tumour necrosis factor inhibitor (TNFi) for psoriatic arthritis over 3 years.

METHODS

PsABio (NCT02627768), a prospective, observational study, followed patients with PsA prescribed first-line to third-line ustekinumab or a TNFi. Persistence and effectiveness (achievement of clinical Disease Activity for PSA (cDAPSA) low disease activity (LDA)/remission and minimal disease activity/very LDA (MDA/VLDA)) were assessed every 6 months. Safety data were collected over 3 years. Analyses to compare the modes of action were adjusted on baseline differences by propensity scores (PS).

RESULTS

In 895 patients (mean age 49.8 years, 44.7% males), at 3 years, the proportion of patients still on their initial treatments was similar with ustekinumab (49.9%) and TNFi (47.8%). No difference was seen in the risk of stopping/switching; PS-adjusted hazard ratio (95% CI) for stopping/switching ustekinumab versus TNFi was 0.87 (0.68 to 1.11). In the overall population, cDAPSA LDA/remission was achieved in 58.6%/31.4% ustekinumab-treated and 69.8%/45.0% TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.89 (0.63 to 1.26) for cDAPSA LDA; 0.72 (0.50 to 1.05) for remission. MDA/VLDA was achieved in 41.4%/19.2% of ustekinumab-treated and 54.2%/26.9% of TNFi-treated patients with overlapping PS-adjusted ORs. A greater percentage of TNFi-treated patients achieved effectiveness outcomes. Both treatments exhibited good long-term safety profiles, although ustekinumab-treated patients had a lower rate of adverse events (AEs) versus TNFi.

CONCLUSION

At 3 years, there was generally comparable persistence after ustekinumab or TNFi treatment, but AE rates were lower with ustekinumab.

Persistence and effectiveness of the IL-12/23 pathway inhibitor ustekinumab or tumour necrosis factor inhibitor treatment in patients with psoriatic arthritis: 1-year results from the real-world PsABio Study

OBJECTIVE

We evaluated real-world treatment persistence and effectiveness at 1 year following initiation of IL-12/23 inhibitor ustekinumab or a tumour necrosis factor inhibitor (TNFi) for psoriatic arthritis (PsA).

METHODS

PsABio (NCT02627768), a prospective, observational study, followed patients with PsA prescribed first-line to third-line ustekinumab or TNFi. Drug persistence, effectiveness (achievement of clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) low disease activity (LDA)/remission and minimal disease activity/very low disease activity (MDA/VLDA)), and safety were assessed every 6 months. In addition to descriptive statistics, propensity score (PS)-adjusted comparisons across cohorts were performed.

RESULTS

At 1 year, overall persistence was similar in the ustekinumab (n=317/438, 72.4%) and TNFi (n=321/455, 70.5%) groups. PS-adjusted HR (95% CI) for stopping/switching ustekinumab versus TNFi was 0.82 (0.60; 1.13). cDAPSA LDA (including remission)/remission was achieved in 55.9%/22.1% of ustekinumab-treated and 67.1%/31.7% of TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.80 (0.57; 1.10) for cDAPSA LDA and 0.73 (0.49; 1.07) for remission. MDA/VLDA was achieved in 34.2%/11.9% of ustekinumab-treated and 43.1%/12.6% of TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.89 (0.63; 1.26) for MDA and 0.90 (0.54; 1.49) for VLDA. The safety profiles were similar in both groups.

CONCLUSION

In the real-world PsABio Study, after 1 year of treatment, although unadjusted persistence was numerically slightly higher for ustekinumab versus TNFi and unadjusted effectiveness was numerically slightly higher for TNFi versus ustekinumab, the PS-adjusted comparisons demonstrated comparable overall persistence, effectiveness and safety for both modes of action in PsA.

New-Onset Inflammatory Bowel Diseases Among IL-17 inhibitors-Treated Patients: Results From The Case-Control MISSIL Study

OBJECTIVES

To describe new-onset inflammatory bowel diseases (new IBD) in patients treated with interleukin 17 inhibitors (IL-17i), to assess their incidence and to identify their risk factors in real life.

METHODS

A French national registry (MISSIL) aimed to report all cases of new IBD in patients treated with IL-17i from January 2016 to December 2019. Using the estimated number of patients treated by IL-17 in France during the study period, the annual incidence rates of new IBD was reported in IL-17i-treated patients. A case-control study was performed with two controls per new IBD case matched by gender, age and underlying inflammatory disease.

RESULTS

31 cases of new IBD under IL-17i were collected: 27 patients treated for spondyloarthritis and 4 patients for psoriasis. All were observed with secukinumab (SEK). The median time to onset of new IBD symptoms was 4.0 (1.5-7.5) months. SEK was discontinued in all patients. The evolution was favourable with complete resolution (17/31), improvement (7/31) or stabilization (5/31). 2 patients died: one due to a massive myocardial infarction and one due to post-colectomy complications. The incidence of new IBD decreased from 0.69/100 PY (7/1010) in 2016, to 0.08/100PY (6/7951) in 2019. No previous treatment with etanercept (OR = 0.33, IC95% 0.14-0.80, p= 0.014) and low number of previous biological therapies (OR = 0.67, 95%CI 0.47-0.94, p= 0.021) were significantly associated with new IBD.

CONCLUSION

The incidence of new IBD was low and decreased from 2016 to 2019. The outcome was favourable in 24 out of 31 patients, but two patients died.

Effectiveness of IL-12/23 inhibition (ustekinumab) versus tumour necrosis factor inhibition in psoriatic arthritis: observational PsABio study results

OBJECTIVES

To evaluate 6-month effectiveness of ustekinumab versus tumour necrosis factor inhibitor (TNFi), analysing predictors of low disease activity (LDA)/remission.

METHODS

PsABio is a prospective, observational cohort study of patients with psoriatic arthritis (PsA) at 92 sites in eight European countries, who received first-line to third-line ustekinumab or a TNFi. Comparative achievement at 6 months of clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) LDA/remission, and minimal disease activity (MDA)/very LDA using propensity score (PS)-adjusted multivariate logistic regression was assessed.

RESULTS

In the final analysis set of 868 participants with 6-month follow-up data (ustekinumab, n=426; TNFi, n=442), with long-standing disease and a high mean cDAPSA score (31.0 vs 29.8, respectively), proportions of patients in ustekinumab/TNFi treatment groups achieving cDAPSA LDA at 6 months were 45.7%/50.7%. cDAPSA remission was achieved in 14.9%/19.2%, and MDA in 26.4%/30.8% of patients. PS-adjusted odds ratios (OR; 95% confidence interval (CI)) of reaching cDAPSA LDA and MDA were 0.73 (0.46 to 1.15) and 0.87 (0.61 to 1.25) with ustekinumab versus TNFi, indicating no significant difference. High baseline body mass index or high cDAPSA were associated with a lower chance (OR (95% CI)) of reaching cDAPSA LDA with TNFi (0.94 (0.89 to 0.99) and 0.64 (0.52 to 0.79), respectively). Predictive factors were similar to previously published evidence, with cDAPSA and 12-item Psoriatic Arthritis Impact of Disease scores and chronic widespread pain at baseline appearing as new risk factors for unfavourable outcome. Safety data were similar between groups.

CONCLUSION

Treatment targets were reached similarly after 6 months of treatment with ustekinumab and TNFi.

Secukinumab and ustekinumab treatment in psoriatic arthritis: results of a direct comparison

OBJECTIVES

To evaluate the characteristics of patients (pts) with PsA treated by ustekinumab (UST) or secukinumab (SEK) and to compare real-world persistence of UST and SEK in PsA.

METHODS

In this retrospective, national, multicentre cohort study, pts with PsA (CASPAR criteria or diagnosis confirmed by the rheumatologist) initiating UST or SEK with a follow-up ≥6 months were included from January 2011 to April 2019. The persistence between SEK and UST was assessed after considering the potential confounding factors by using pre-specified propensity-score methods. Causes of discontinuation and tolerance were also collected.

RESULTS

A total of 406 pts were included: 245 with UST and 161 with SEK. The persistence rate was lower in the UST group compared with the SEK group [median persistence 9.4 vs 14.7 months; 26.4% vs 38.0% at 2 years; weighted hazard ratio (HR) = 1.42; 95% CI: 1.07, 1.92; P =0.015]. In subgroup analysis, the persistence rate of SEK associated with MTX was significantly higher than that of UST associated with MTX: HR = 2.20; 95% CI: 1.30, 3.51; P =0.001, in contrast to SEK vs UST monotherapy: HR = 1.06; 95% CI: 0.74, 1.53; P =0.75. Discontinuation due to inefficacy was reported in 91.7% (SEK) and 82.4% (UST) of pts. Discontinuation due to an adverse event was reported in 12.2% (SEK) and 7.7% (UST) of pts.

CONCLUSION

In this first study comparing UST and SEK, the persistence of SEK was higher than that of UST in PsA. In subgroup analysis, this difference was only found in association with MTX.

Evaluation of the Feasibility of a Web-Based Survey to Assess Patient-Reported Symptom Improvement and Treatment Satisfaction Among Patients with Psoriatic Arthritis Receiving Secukinumab

BACKGROUND AND OBJECTIVE

Patient perspectives regarding treatment experience and satisfaction may be useful for clinicians when making treatment strategies. This US-based study assessed the feasibility of evaluating real-world, patient-reported narratives regarding symptom improvement and treatment satisfaction among patients with psoriatic arthritis treated with secukinumab.

METHODS

A cross-sectional, web-based survey collected data on demographics, disease characteristics, symptoms before and after secukinumab use, and treatment satisfaction with secukinumab.

RESULTS

Of 2755 patients screened, 200 patients with psoriatic arthritis were eligible and included in the analysis. Their mean age was 36.0 (standard deviation, 10.0) years; 55.5% were male and 75.0% were white. Most (87.5%) were biologic experienced; the primary reason for discontinuation of their previous treatment was lack of effectiveness (28.6%). Most patients (79.9%) reported overall psoriatic arthritis symptom improvement after secukinumab initiation compared with before secukinumab initiation; a similar trend was observed for all individual symptoms evaluated. Approximately half of patients reported improvement within 4 weeks after starting secukinumab treatment, and > 90% reported improvement within 6 months. Most patients (≥ 96%) expressed overall satisfaction with secukinumab regarding symptom improvement, speed of symptom improvement, frequency of administration, method of administration, ease of use, patient support services, and side effects, if any.

CONCLUSIONS

Patient-reported perspectives may be feasibly collected to provide insights into treatment experience and satisfaction of secukinumab. Most patients with psoriatic arthritis in our real-world study experienced symptom improvement after initiating secukinumab; > 50% of patients reported symptom improvement within 4 weeks. Additionally, almost all patients reported satisfaction with secukinumab treatment.
