NCT01111305 ↗	Reslizumab to Prevent Post-treatment Eosinophilia in Loiasis	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 2	2010-04-01	Diethylcarbamazine citrate (DEC) treatment of Loa loa infection is complicated by the development of severe adverse reactions that are correlated with the number of circulating microfilariae in the blood. The cause of these reactions is unknown, but they are accompanied by a dramatic interleukin-5 (IL-5)-dependent increase in eosinophilia and evidence of eosinophil activation. This randomized, placebo-controlled, double-blind pilot study (conducted at the NIH Clinical Center) will assess whether and to what extent the administration of reslizumab (Cinquil ), a humanized monoclonal antibody directed against IL-5, given 3 to 7 days before administration of the anthelminthic drug DEC (at 3 mg/kg 3 times daily for 21 days), prevents the development of eosinophilia in 10 adult subjects with Loa loa infection and 0-5000 microfilariae/mL. Secondary outcomes will include the severity of post-treatment effects, markers of eosinophil activation, and effects of reslizumab on microfilarial clearance.
NCT01270464 ↗	A Study to Evaluate the Efficacy and Safety of Reslizumab (0.3 or 3.0 mg/kg) as Treatment for Patients (12-75 Years of Age) With Eosinophilic Asthma	Completed	Teva Branded Pharmaceutical Products R&D, Inc.	Phase 3	2011-02-01	The primary objective of this study is to determine whether reslizumab, at a dosage of 0.3 or 3.0 mg/kg administered once every 4 weeks for a total of 4 doses, is more effective than placebo in improving lung function in patients with eosinophilic asthma as assessed by the overall change from baseline in forced expiratory volume in 1 second (FEV1).
