Long-Term Safety of Risankizumab in Patients with Psoriatic Disease: A Comprehensive Analysis from Clinical Trials.

INTRODUCTION: Risankizumab has demonstrated a favourable safety profile in patients with psoriatic disease (moderate-to-severe psoriasis [PsO] and psoriatic arthritis [PsA]). We evaluated the long-term safety of risankizumab in psoriatic disease. METHODS: Long-term safety was evaluated by analysing data from 20 (phase 1-4) clinical trials for plaque PsO and four (phase 2-3) trials for PsA. Treatment-emergent adverse events (TEAEs) and AEs in areas of special interest were reported among patients receiving ≥ 1 dose of risankizumab. Exposure-adjusted event rates were presented as events (E) per 100 patient-years (PY). RESULTS: The long-term safety data analyses included 3658 patients with PsO (13,329.3 PY) and 1542 patients with PsA (3803.0 PY). The median (range) treatment duration for patients with PsO and PsA was 4.1 (0.2-8.8) years and 2.8 (0.2-4.0) years, respectively. In the PsO population, rates of TEAEs, serious AEs and AEs leading to discontinuation were 145.5 E/100 PY, 7.4 E/100 PY and 1.9 E/100 PY, respectively; in the PsA population, these rates were 142.6 E/100 PY, 8.6 E/100 PY, and 1.8 E/100 PY, respectively. The rates of serious infections (excluding COVID-19-related infections) in the PsO and PsA populations were 1.2 and 1.4 E/100 PY, respectively. The rates of opportunistic infections (excluding tuberculosis and herpes zoster) were low (< 0.1 E/100 PY) in both populations. The rates of both nonmelanoma skin cancer (NMSC) and malignant tumours excluding NMSC were 0.6 and 0.5 E/100 PY in PsO and PsA, respectively, which are within the benchmarks of prior epidemiological studies. Adjudicated major cardiovascular event rates were 0.5 E/100 PY in PsO and 0.3 E/100 PY in PsA, which are within the epidemiologic reference benchmarks for both indications. No additional safety concerns were identified with this long-term exposure. CONCLUSIONS: The results support the favourable safety profile of risankizumab for long-term treatment of psoriatic disease with no new safety concerns and similar safety profiles among both PsO and PsA populations.

Rapid onset of efficacy predicts response to therapy with certolizumab plus methotrexate in patients with active rheumatoid arthritis.

BACKGROUND/AIMS: The objective of this study was to determine the efficacy and safety of add-on therapy with certolizumab pegol (CZP) in active rheumatoid arthritis (RA) patients of a single ethnicity. METHODS: In this 24-week, phase 3, randomized, double-blind, placebo-controlled trial, eligible patients (n = 127) were randomized 2:1 to subcutaneous CZP + methotrexate (MTX; 400 mg at week 0, 2, and 4 followed by 200 mg every 2 weeks) or placebo + MTX. RESULTS: At week 24, the American College of Rheumatology criteria for 20% (ACR20) response rate was significantly greater with CZP + MTX than with placebo (66.7% vs. 27.5%, p < 0.001). Differences in ACR20 response rates for CZP vs. placebo were significant from week 1 (p < 0.05) and remained significant through week 24. The CZP group reported significant improvement in physical function and disability compared to the placebo group (p < 0.001) at week 24, as assessed by Korean Health Assessment Questionnaire-Disability Index (KHAQ-DI). Post hoc analysis indicated that the proportion of patients who had ACR70 responses, Disease Activity Score 28 (DAS28) low disease activity, and DAS28 remission at week 24 was greater in CZP + MTX-treated patients who achieved a decrease in DAS28 ≥ 1.2 (43.8%) at week 4 than in nonresponders. Among 18 (22.2%) and 14 patients (35.0%) in CZP and placebo groups who had latent tuberculosis (TB), none developed active TB. Most adverse events were mild or moderate. CONCLUSION: CZP treatment combined with MTX in active RA patients with moderate to severe disease activity and an inadequate response to MTX resulted in rapid onset of efficacy, which is associated with better clinical outcome at week 24 and has an acceptable safety profile, especially in an intermediate TB-burden population.

Efficacy of Epratuzumab, an Anti-CD22 Monoclonal IgG Antibody, in Systemic Lupus Erythematosus Patients With Associated Sjögren's Syndrome: Post Hoc Analyses From the EMBODY Trials.

OBJECTIVE: EMBODY 1 (ClinicalTrials.gov identifier: NCT01262365) and EMBODY 2 (ClinicalTrials.gov identifier: NCT01261793) investigated the efficacy and safety of epratuzumab, a CD22-targeted humanized monoclonal IgG antibody, in patients with systemic lupus erythematosus (SLE). The studies showed no significant difference from placebo in primary or secondary clinical outcome measures but did demonstrate B cell-specific immunologic activity. The aim of this post hoc analysis was to determine whether epratuzumab had a different clinical efficacy profile in SLE patients with versus those without an associated diagnosis of Sjögren's syndrome (SS). METHODS: The efficacy and safety of epratuzumab were compared between 2 patient subpopulations randomized in EMBODY 1 and 2: SLE patients with and those without a diagnosis of associated SS. British Isles Lupus Assessment Group (BILAG) total score, BILAG-based Combined Lupus Assessment (BICLA) clinical response to treatment, biologic markers (including B cells, IgG, IgM, and IgA), and safety were assessed. RESULTS: A total of 1,584 patients were randomized in the EMBODY 1 and EMBODY 2 trials; 113 patients were anti-SSA positive and had a diagnosis of associated SS, and 1,375 patients (86.8%) had no diagnosis of associated SS (918 patients were randomized to receive epratuzumab and 457 to receive placebo). For patients with associated SS, but not those without associated SS, a higher proportion of patients receiving epratuzumab achieved a BICLA response and a reduction from baseline in BILAG total score. B cell reduction was faster in patients with associated SS. The sensitivity of B cells to epratuzumab as measured by the mean concentration producing 50% of the maximum B cell count depletion was lower for patients with associated SS (9.5 µg/ml) versus the total EMBODY population (87.1 µg/ml). No difference in the frequency of adverse events in those receiving placebo was reported. CONCLUSION: Patients with SLE and associated SS treated with epratuzumab showed improvement in SLE disease activity, which was associated with bioactivity, such as decreases in B cell number and IgM level.

A Randomized Trial Comparing Disease Activity Measures for the Assessment and Prediction of Response in Rheumatoid Arthritis Patients Initiating Certolizumab Pegol.

OBJECTIVE: The aim of the Patient/Physician Reported Efficacy Determination In Clinical Practice Trial (PREDICT; ClinicalTrials identifier NCT01255761) was to compare the patient-reported Routine Assessment of Patient Index Data 3 (RAPID-3) instrument with the investigator-based Clinical Disease Activity Index (CDAI) for assessing certolizumab pegol (CZP) treatment response in rheumatoid arthritis patients at 12 weeks and to predict the treatment response at week 52 using the data from week 12 (coprimary end points). METHODS: Patients received 400 mg of CZP at weeks 0, 2, and 4 (loading dose), followed by 200 mg every 2 weeks thereafter. Patients were randomized 1:1 to assessment with the RAPID-3 or the CDAI. Responder classification was performed at week 12; treatment response was defined as a score of ≤6 or a 20% improvement over baseline on the RAPID-3 or a score of ≤10 or a 20% improvement over baseline on the CDAI. Long-term treatment success was defined as a Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR) of ≤3.2 at week 52. Comparisons were made for the coprimary end points using noninferiority methods. Patients with improvement of <1 on the CDAI score or with no improvement on the RAPID-3 score at week 12 or patients with high levels of disease activity (CDAI score >22 or RAPID-3 score >12) at 2 consecutive visits were withdrawn from the study. RESULTS: Patients had longstanding disease (mean 8.9 years) and high levels of disease activity (mean scores of 6.3 on the DAS28-ESR, 16.1 on the RAPID-3, and 40.2 on the CDAI). Previous anti-tumor necrosis factor therapy had failed in 55.5% of them. At week 12, a total of 64.7% (by RAPID-3) and 76.4% (by CDAI) of the patients were classified as responders (difference of -11.9% [95% confidence interval -18.4%, -5.3%]). At week 52, a total of 31.5% (by RAPID-3) and 32.3% (by CDAI) of the responders achieved a low level of disease activity on the DAS28-ESR (difference of -1.3% [95% confidence interval -9.3%, 6.6%]). CONCLUSION: The CDAI classified more patients as CZP responders at week 12 than did the RAPID-3. Although these outcome measures were not statistically comparable, the positive predictive value for low disease activity at week 52 was similar. As these tools cover differing domains of therapy response, further evaluation for clinical disease activity assessments and treatment decisions is needed.

Assessing the long-term impact of drug court participation on recidivism with generalized estimating equations.

Drug courts are one of the most common strategies for dealing with the large proportion of criminal offenders who are drug-involved, yet methodological limitations limit the conclusions that can be drawn from many existing evaluations of their effectiveness. The current study examined the long-term impact of drug court participation compared to regular probation on the recidivism of 475 drug-involved offenders under supervision in Hillsborough County, Florida. Using a combination of self-reported data (collected through in-person interviews at baseline, i.e., the beginning of supervision) and administrative records, the study employed a repeated measures framework (examining five 6-month time periods from baseline to 30 months post-baseline) and generalized estimating equations to compare the likelihood of being arrested between drug court participants and a matched sample of comparison offenders. The results indicate that participation in drug court was associated with a significant decrease in the likelihood of being arrested in the 12-18 months post-baseline time period. Although the drug court effect was somewhat delayed (it was not significant prior to 12 months) and short-lived (it was not significant after 18 months), the fact that significant program effects were observed during a time period that coincides with the conclusion of drug court participation for graduates and a time period well beyond initial program exposure, suggests that drug court participants are more likely than comparable offenders not exposed to drug court to remain arrest free when no longer under community supervision.
