Comparison of two etanercept regimens for treatment of psoriasis and psoriatic arthritis: PRESTA randomised double blind multicentre trial.

OBJECTIVES: To compare the efficacy over 12 weeks of two different etanercept regimens in treating the skin manifestations of psoriasis in patients who also have psoriatic arthritis and to evaluate efficacy and safety over an additional 12 weeks of open label etanercept treatment. Design Randomised double blind multicentre outpatient study. SETTING: 98 outpatient facilities in Europe, Latin America, and the Asia Pacific region. Participants 752 patients with both psoriasis (evaluated by dermatologists) and psoriatic arthritis (evaluated by rheumatologists). INTERVENTIONS: During the blinded portion of the study, participants were randomised to receive etanercept 50 mg twice weekly (n=379) or 50 mg once weekly (n=373) for 12 weeks by subcutaneous injection. All participants then received open label etanercept 50 mg once weekly for 12 additional weeks, while remaining blinded to the regimen. MAIN OUTCOME MEASURES: The primary efficacy end point was the proportion of participants achieving "clear" or "almost clear" on the physician's global assessment of psoriasis at week 12. Secondary efficacy analyses included psoriasis area and severity index, American College of Rheumatology responses, psoriatic arthritis response criteria, and improvement in joint and tendon disease manifestations. RESULTS: At week 12, 46% (176/379) of participants receiving etanercept 50 mg twice weekly achieved a physician's global assessment of psoriasis of "clear" or "almost clear" compared with 32% (119/373) in the group treated with 50 mg once weekly (P<0.001). In contrast, an equally high percentage of participants in both groups achieved psoriatic arthritis response criteria (77% (284/371) in the twice weekly/once weekly group versus 76% (282/371) in the once weekly/once weekly group). Participants treated with 50 mg twice weekly/once weekly had greater mean reductions from baseline in the psoriasis area and severity index at week 12 compared with those who received 50 mg once weekly/once weekly (71% v 62%, P<0.001), with less difference at week 24 (78% v 74%, P<0.110). Joint and tendon disease manifestations improved from baseline in both groups to a similar extent. No new safety signals were seen in either etanercept treatment group, and no significant difference in the safety profiles was observed. CONCLUSIONS: In participants with active psoriasis and psoriatic arthritis, initial treatment of the psoriasis with etanercept 50 mg twice weekly may allow for more rapid clearance of skin lesions than with 50 mg once weekly. A regimen of 50 mg once weekly seems to be appropriate for treatment of joint and tendon rheumatic symptoms. The choice of regimen should be determined by the clinical needs of the individual patient. TRIAL REGISTRATION: Clinical trials NCT00245960.

Evaluation of parental preference for the treatment of asthmatic children aged 6 to 11 years with oral montelukast or inhaled cromolyn: a randomized, open-label, crossover study.

The objective of this study was to evaluate parental preference for the treatment of asthmatic children with oral montelukast sodium or inhaled cromolyn sodium. Additionally, we wanted to compare the two drugs in terms of patient preference for treatment, patient and parent satisfaction with treatment, frequency of inhaled albuterol use, adherence to treatment, and safety. This was a 12-week randomized, open-label, crossover study conducted in 42 primary care and asthma/allergy specialty centers in the United States. Three hundred thirty-three asthmatic patients, ages 6 to 11 years, who had a forced expiratory volume in 1 second (FEV1) of 60%-85% (inclusive) of predicted value with > or = 12% reversibility after administration of an inhaled beta-agonist and who used albuterol on at least 7 of the last 14 days of the run-in period. After a 2- to 3-week run-in period, patients were randomized either to 4 weeks of montelukast (5-mg chewable tablet once daily) followed by a 2-week washout period, then 4 weeks of cromolyn (two puffs 4 times daily from a metered-dose inhaler) or to the reverse sequence. More parents preferred montelukast (87%) than cromolyn (12%; p < 0.001). More patients preferred montelukast (82%) than cromolyn (17%; p < 0.001). Daily albuterol use (puffs/day) was reduced by 38% during montelukast therapy vs. 23% during cromolyn therapy. Seventy-eight percent of patients reported being highly adherent to montelukast therapy compared with 42% to cromolyn therapy (p < 0.001). Fewer patients receiving montelukast discontinued because of asthma exacerbation (1.0% vs. 5.0%, respectively), and fewer patients reported worsening asthma while receiving montelukast (3.5% vs. 7.5%, p = 0.036). Parents' and patients' preference, parents' and patients' satisfaction, and patients' adherence to therapy were all significantly better with oral montelukast compared with inhaled cromolyn. Beta-agonist use was decreased when taking montelukast, which was safe and well-tolerated.
