Safety of Adalimumab Dosed Every Week and Every Other Week: Focus on Patients with Hidradenitis Suppurativa or Psoriasis.

BACKGROUND: Adalimumab is approved for the treatment of hidradenitis suppurativa (HS), plaque psoriasis, and other inflammatory conditions. OBJECTIVE: Our objective was to examine the safety of adalimumab administered every other week (EOW) and every week (EW) in patients with HS and psoriasis and to investigate informative data from non-dermatologic indications. METHODS: The safety of adalimumab 40-mg EOW versus EW dosing was examined during placebo-controlled and open-label study periods in patients with HS (three studies), psoriasis (two studies), Crohn's disease (six studies), ulcerative colitis (three studies), and rheumatoid arthritis (one study). RESULTS: No new safety risks or increased rates of particular adverse events (AEs) were identified with EW dosing. In patients with HS or psoriasis, the overall safety of adalimumab 40-mg EOW and EW was generally comparable. In studies of adalimumab for non-dermatologic indications, including Crohn's disease, ulcerative colitis, and rheumatoid arthritis, the overall AE rates were similar for EW and EOW dosing. CONCLUSION: In patients with HS or psoriasis, the safety of adalimumab EW and EOW was comparable and consistent with the expected adalimumab AE profile. The safety of adalimumab EW dosing in patients with dermatologic conditions is supported by data comparing adalimumab EW and EOW dosing for Crohn's disease, ulcerative colitis, and rheumatoid arthritis.

Body Region Involvement and Quality of Life in Psoriasis: Analysis of a Randomized Controlled Trial of Adalimumab.

BACKGROUND: Psoriasis severity and treatment responsiveness vary by body region, which differentially impacts quality of life (QoL). OBJECTIVE: The objective of the study was to examine adalimumab efficacy by body region and regional response and QoL relationship. METHODS: Patients (n = 1212) with moderate-to-severe psoriasis were randomized 2:1 to 80 mg at week 0, followed by adalimumab 40 mg or placebo every other week for 16 weeks in the double-blind REVEAL study. Psoriasis Area and Severity Index (PASI) responses and Dermatology Life Quality Index outcomes were analyzed. RESULTS: Week 16 regional mean PASI improvements were significantly greater with adalimumab (83.1 ± 1.57, 81.3 ± 1.58, 75.7 ± 1.34, and 73.9 ± 1.26% in the trunk, head, upper extremities, and lower extremities, respectively; all p < 0.001 vs. placebo). Likewise, percentages of patients with regional PASI ≥75/≥90/100% reduction from baseline were significantly higher with adalimumab (all p < 0.001); adalimumab responses were greater for the trunk (77.9/65.0/59.1%) and head (74.6/66.1/62.8%; all p ≤ 0.0001 vs. lower) than upper (67.7/45.1/39.6%; p = 0.4, p = 0.04, p = 0.0005, respectively, vs. lower) and lower extremities (65.7/40.0/31.3%). Adalimumab significantly improved Dermatology Life Quality Index scores vs. placebo (8.2- vs 1.7-point decrease from baseline; p < 0.001). LIMITATIONS: The study was a post hoc analysis. CONCLUSIONS: Adalimumab treatment resulted in statistically significant and clinically meaningful improvements in disease severity and QoL. QoL improvements were associated with PASI responses in all body regions. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT00237887.

Adalimumab Efficacy in Patients with Psoriasis Who Received or Did Not Respond to Prior Systemic Therapy: A Pooled Post Hoc Analysis of Results from Three Double-Blind, Placebo-Controlled Clinical Trials.

INTRODUCTION: There are limited data from randomized controlled clinical trials on the outcomes of biologics after discontinuation of a different systemic therapy. To determine the efficacy of adalimumab in patients who previously received systemic therapy (including failed therapy), we performed a pooled post hoc analysis of Psoriasis Area and Severity Index (PASI) response data from three double-blind, placebo-controlled clinical trials in patients with moderate to severe psoriasis. METHODS: Patients from the M02-528, REVEAL, and CHAMPION studies who were previously exposed to systemic treatment were categorized based on their response. The efficacy of adalimumab compared with placebo was analyzed at the end of the double-blind treatment period for the overall pooled intent-to-treat population (N = 1469) and subgroups that received (n = 780) or did not respond to (n = 229) previous systemic pretreatments. RESULTS: Rates for an improvement of ≥75% from baseline in the PASI score (PASI75 response) were significantly greater (p < 0.001) at week 16 in patients treated with adalimumab compared with patients who received placebo in the overall (72.1 vs. 8.0%, respectively), previously treated (72.7 vs. 8.5%), and previously failed treatment (70.4 vs. 8.1%) groups. PASI75 response rates were similar in the overall group and in patients who did not respond to methotrexate, cyclosporine, or psoralen plus ultraviolet A therapy. Improvements of ≥90 or ≥100 % from baseline PASI score were also higher with adalimumab vs. placebo in previously treated patients. Adverse events were similar among subgroups. CONCLUSIONS: Adalimumab was efficacious for the treatment of moderate to severe psoriasis regardless of prior exposure to systemic therapies or failure of those prior therapies. CLINICALTRIALS.

Final 10-year effectiveness and safety results from study DE020: adalimumab treatment in patients with rheumatoid arthritis and an inadequate response to standard therapy.

OBJECTIVE: To evaluate the long-term effectiveness and safety of 10 years of adalimumab (ADA) treatment in DMARD-refractory RA patients and to analyse efficacy based on RF status and baseline disease duration. METHODS: DE020 was a multicentre, phase 3, open-label continuation study. Adult RA patients who received s.c. ADA (40 mg every other week or monthly) in one of four early assessment studies could receive ADA for ≤10 years in DE020. Assessments included the 28-joint DAS with CRP (DAS28-CRP), Simplified Disease Activity Index (SDAI), HAQ Disability Index (HAQ-DI) and safety as events per 100 patient-years. RESULTS: Of 846 enrolled patients, mean age at baseline was 55.6 years, 78.1% were women, mean disease duration was 11.7 years and 27.0% were RF(-). Among 286 (33.8%) patients who completed 10 years of ADA, 168/236 (71.2%) achieved DAS28-CRP ≤3.2, 101/238 (42.4%) achieved HAQ-DI <0.5 and 90/241 (37.3%) achieved DAS28-CRP ≤3.2 plus HAQ-DI <0.5. DAS28-CRP- or SDAI-based remission was observed in 135/236 (57.2%) and 70/236 (29.7%) patients, respectively. Effectiveness outcomes were similar regardless of RF status. Higher proportions of patients with shorter vs longer baseline disease duration (≤2 vs >2 years) achieved HAQ-DI <0.5 (60.6% vs 39.5%; P = 0.023) and DAS28-CRP ≤3.2 plus HAQ-DI <0.5 (58.1% vs 32.5%; P = 0.006). Adverse events (317.2 events per 100 patient-years) during ADA exposure were consistent with the expected safety profile for TNF inhibitors. CONCLUSION: ADA led to sustained clinical and functional responses in the 33.8% of treatment-refractory RA patients who completed 10 years of treatment. Patients with shorter disease duration achieved better outcomes, highlighting the need for early treatment. No unexpected safety findings were observed.

Pioglitazone plus a sulphonylurea or metformin is associated with increased lipoprotein particle size in patients with type 2 diabetes.

OBJECTIVE: To determine the effect of pioglitazone plus metformin or a sulphonylurea on lipoprotein particle size and subclass distribution in patients with type 2 diabetes. METHODS: Lipid profiles were determined for blood samples from patients participating in two randomised, double-blind, 24-week studies of pioglitazone 30 mg or 45 mg daily plus either metformin or a sulphonylurea. RESULTS: Samples from 177 patients were evaluated; 96 of these patients received a sulphonylurea, and 81 received metformin. Pioglitazone combination treatment produced significant increases from baseline for average and peak low-density lipoprotein (LDL) particle size at weeks 12 and 24 (p<0.0001 for each; range 0.29-0.39 nm for average and 0.36-0.55 nm for peak particle size, respectively). Significant shifts in high-density lipoprotein (HDL) and LDL distribution showed an increase in large particles and a decrease in small particles. For pioglitazone plus metformin, significant increases in levels of apolipoprotein (Apo) Al, Apo Al/All-containing HDL, and lipoprotein(a) also were noted, whereas Apo B levels decreased. CONCLUSIONS: These observed changes are thought to affect the atherogenic profile positively. Therefore, pioglitazone combination treatment may lead to decreased cardiovascular risk in patients with type 2 diabetes.
