Efficacy of Reslizumab Dose Escalation in Patients With Severe Asthma

Asthma; Eosinophilic Clinical Trial

Official title: Efficacy of Reslizumab Dose Escalation in Patients With Severe Asthma and Persistent Sputum Eosinophilia Despite Standard Dose Therapy

Status Completed

Clinical Trial Summary

Dose escalation of reslizumab can ameliorate sputum eosinophilia in severe asthmatics who have persistent sputum eosinophilia despite treatment with reslizumab at the standard dose.

Clinical Trial Description

Monoclonal antibody therapies targeting the interleukin-5 (IL-5) pathway, critical for maintaining eosinophil homeostasis, have been developed as adjunct therapy for severe asthma with an eosinophilic phenotype. Reslizumab/Cinqair is an approved/marketed product administered monthly by intravenous to severe eosinophilic asthmatics at 3mg/kg. However some patients do exhibit sputum eosinophilia at this dosage. We are investigating whether those that receive 3mg/kg that have persistent sputum eosinophils would benefit at a higher dose of 4mg/kg and those that still exhibit sputum eosinophils at this elevated dose would show improvement at 5mg/kg. The overall aim of this study is to determine whether dose escalation of reslizumab can ameliorate sputum eosinophilia in severe asthmatics who have persistent sputum eosinophilia despite treatment with reslizumab at the standard dose. ;
