Apremilast Use in Severe Psoriasis: Real-World Data from Central and Eastern Europe.

INTRODUCTION: The broad and sustained efficacy of apremilast for psoriasis has been demonstrated in randomized and real-world observational studies. Data from Central and Eastern Europe (CEE) are lacking. Moreover, apremilast use in this region is limited by country-specific reimbursement criteria. This is the first study to report data on the real-world use of apremilast in the region. METHODS: APPRECIATE (NCT02740218) was an observational, retrospective, cross-sectional study assessing psoriasis patients 6 (± 1) months after apremilast treatment initiation. The study aimed to describe the characteristics of patients with psoriasis receiving apremilast, estimate treatment outcomes, including Psoriasis Area Severity Index (PASI), Body Surface Area (BSA), and Dermatology Life Quality Index (DLQI), and assess dermatologists' and patients' perspectives on treatment using questionnaires including the Patient Benefit Index (PBI). Adverse event reports were taken from the medical records. RESULTS: Fifty patients (Croatia: 25; Czech Republic: 20; Slovenia: 5) were enrolled. In patients continuing apremilast at 6 (± 1) months, mean (± SD) PASI score was reduced from 16.2 ± 8.7 points at treatment initiation to 3.1 ± 5.2 at 6 (± 1) months; BSA from 11.9% ± 10.3% to 0.8% ± 0.9%; DLQI from 13.7 ± 7.4 points to 1.6 ± 3.2. PASI 75 was reached by 81% of patients. Physicians reported that the overall treatment success fulfilled their expectations in more than two thirds of patients (68%). At least three-quarters of patients reported apremilast had a quite or very high benefit on the needs they identified as being most important. Apremilast was well tolerated; no serious or fatal adverse events were identified. CONCLUSION: Apremilast was effective in reducing skin involvement and improving quality of life in CEE patients having severe disease. Treatment satisfaction among physicians and patients was very high. These data add to the growing body of evidence showing consistent effectiveness of apremilast across the continuum of psoriasis disease severity and manifestations.

Infliximab treatment of intravenous immunoglobulin-resistant Kawasaki disease.

OBJECTIVE: To investigate the safety, tolerability, and pharmacokinetics of the anti-tumor necrosis factor-alpha monoclonal antibody infliximab in subjects with intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD). STUDY DESIGN: We conducted a multicenter, randomized, prospective trial of second IVIG infusion (2 g/kg) versus infliximab (5 mg/kg) in 24 children with acute KD and fever after initial treatment with IVIG. Primary outcome measures were the safety, tolerability, and pharmacokinetics of infliximab. Secondary outcome measures were duration of fever and changes in markers of inflammation. RESULTS: Study drug infusions were associated with cessation of fever within 24 hours in 11 of 12 subjects treated with infliximab and in 8 of 12 subjects retreated with IVIG. No infusion reactions or serious adverse events were attributed to either study drug. No significant differences were observed between treatment groups in the change from baseline for laboratory variables, fever, or echocardiographic assessment of coronary arteries. CONCLUSIONS: Both infliximab and a second IVIG infusion were safe and well tolerated in the subjects with KD who were resistant to standard IVIG treatment. The optimal management of patients resistant to IVIG remains to be determined.

A prospective open-label trial of Remicade in patients with severe exacerbation of Crohn's disease requiring hospitalization: a comparison with outcomes previously observed in patients receiving intravenous hydrocortisone.

PURPOSE: To evaluate treatment response to intravenous (IV) infliximab (IFX) as a first-line therapy in patients hospitalized for severe Crohn's disease and compare it with our earlier data using IV hydrocortisone. METHODS: Seventeen cases received IFX (5 mg/kg) and were matched for the same goal of therapy to those who had received hydrocortisone (300 mg/d). The Crohn's and Colitis Foundation of America-International Organization of Inflammatory Bowel Disease (CCFA-IOIBD) score was obtained for the IFX-treated cases on admission and daily and the Crohn's disease activity index (CDAI) score weekly throughout the hospitalization and compared with those who received hydrocortisone. Discharge was guided by the same criteria in both groups. RESULTS: For the IFX group, the admission mean CCFA-IOIBD score was 13.5 (+/-4.4). Eight of 17 patients achieved a clinical response with a mean score of 4 (+/-1.5), representing a >or=50% reduction from baseline to discharge. The mean admission score for the hydrocortisone group was 17.75 (+/-7.1) with 13 of 16 achieving a mean score of 4.5 (+/-2.3). The mean discharge score for the 17 IFX patients was 6.9 (+/-3) and for the hydrocortisone group was 5.9 (+/-3.2). Median length of hospitalization for the IFX patients was 4 days (range 1 to 9) and 7.5 (5 to 15) days for the hydrocortisone group (P<0.001). CONCLUSIONS: IFX therapy was an effective first-line agent in patients with severe Crohn's disease who require hospitalization and therefore a primary treatment option. Most patients receiving IFX can anticipate a briefer hospitalization than with IV hydrocortisone. Failure of an early response can provide an opportunity to consider an alternate form of therapy sooner with IFX than with hydrocortisone.

Open-label, pilot protocol of patients with rheumatoid arthritis who switch to infliximab after an incomplete response to etanercept: the opposite study.

OBJECTIVE: To incorporate a new trial design to examine clinical response, cytokine expression and joint imaging in patients with rheumatoid arthritis (RA) switching from etanercept to infliximab treatment. METHODS: A randomised, open-label, clinical trial of 28 patients with an inadequate response to etanercept was conducted. Eligible patients received background methotrexate and were randomised 1:1 to discontinue etanercept and receive infliximab 3 mg/kg at weeks 0, 2, 6, 14 and 22, or to continue etanercept 25 mg twice weekly. Data were analysed for clinical response, serum biomarker levels, radiographic progression, MRI and adverse events. RESULTS: At week 16, 62% of infliximab-treated patients achieved American College of Rheumatology 20% criteria for improvement in RA (ACR20) responses compared with 29% of etanercept-treated patients. A 30.8% decrease from baseline in Disease Activity Score 28 was observed in patients receiving infliximab, compared with a 16.0% decrease in patients receiving etanercept. ACR20 and American College of Rheumatology 50% criteria for improvement in RA responses correlated at least minimally with intracellular adhesion molecule-1 and interleukin 8 in patients receiving infliximab. 38% of patients who were switched to infliximab showed reductions in Health Assessment Questionnaire scores (>0.4), compared with 0% of patients receiving etanercept. MRI analyses were inconclusive. Both drugs were well tolerated; 54% of infliximab-treated patients and 50% of etanercept-treated patients reported adverse events. CONCLUSIONS: In this exploratory, open-label trial (with single-blind evaluator), patients were randomised to continue with etanercept or switch to infliximab. The small sample size of this hypothesis-generating study was underpowered to show statistical differences between groups. There was a numerical trend favouring patients who switched to infliximab, therefore warranting further study with a more rigorous design.

A Phase I and pharmacokinetic study of squalamine, an aminosterol angiogenesis inhibitor.

PURPOSE: The purpose of this study was to assess the feasibility and characterize the pharmacokinetics of squalamine administered as a continuous i.v. infusion daily for 5 days every 3 weeks. EXPERIMENTAL DESIGN: Patients with advanced solid malignancies were treated with escalating doses of squalamine as a 5-day continuous i.v. infusion every 3 weeks. Doses were initially escalated in 100% increments from a starting dose of 6 mg/m(2)/day, with a single patient treated at each dose level until moderate toxicity was observed, at which time additional patients were treated. RESULTS: Thirty-three patients were treated with 73 courses of squalamine at 13 dose levels ranging from 6 to 700 mg/m(2)/day. Hepatotoxicity, characterized by brief, asymptomatic elevations in transaminases and hyperbilirubinemia, was the principal dose-limiting toxicity of squalamine. At 700 mg/m(2)/day, two of three patients developed grade 4 hyperbilirubinemia, which precluded further dose escalation. At 500 mg/m(2)/day, one of seven patients experienced dose-limiting grade 4 hyperbilirubinemia and grade 3 neurosensory changes, which resolved soon after treatment. Squalamine pharmacokinetics were dose-proportional. At 500 mg/m(2)/day, the mean (percentage coefficient of variation) clearance, half-life, and volume of distribution of squalamine were 2.67 liters/h/m(2) (85%), 9.46 h (81%), and 36.84 liters/m(2) (124%), respectively, and steady-state concentrations [20.08 micro g/ml (13%)] were well above those that inhibit angiogenesis in preclinical models. CONCLUSIONS: At the recommended Phase II dose of 500 mg/m(2)/day, squalamine is well tolerated and results in plasma concentrations at least an order of magnitude higher than those required for prominent antiangiogenic effects in preclinical studies.
