Randomized Controlled Trial Multicenter Study
A Proof-of-Concept, Randomized, Controlled Trial of Omalizumab in Patients With Severe, Difficult-to-Control, Nonatopic Asthma.
While up to 50% of patients with severe asthma have no evidence of allergy, IgE has been linked to asthma, irrespective of atopic status. Omalizumab, an anti-IgE monoclonal antibody, is reported to significantly benefit a subset of patients with severe, persistent, allergic asthma. Therefore, we investigated whether omalizumab has biologic and clinical effects in patients with refractory nonatopic asthma. ⋯ Omalizumab negatively regulates FcεRI expression in patients with severe nonatopic asthma, as it does in severe atopic asthma. Omalizumab may have a therapeutic role in severe nonatopic asthma. Nonetheless, our preliminary findings support further investigation to better assess the clinical efficacy of omalizumab.

Meta Analysis Comparative Study
Relative Effects of Two Different Enoxaparin Regimens as Comparators Against Newer Oral Anticoagulants: Meta-analysis and Adjusted Indirect Comparison.
Two different regimens of enoxaparin (40 mg once daily or 30 mg bid) have been used as control arms in trials of new oral anticoagulants. The choice of enoxaparin comparator may influence the perceived relative efficacy and safety of the newer agents, and we aimed to identify any significant differences between the two enoxaparin regimens. ⋯ The use of once-daily enoxaparin regimen as control in clinical trials will lead to more favorable estimates of relative efficacy for the new oral anticoagulants than if enoxaparin 30 mg bid had been chosen as a comparator.
