	Description	Reslizumab is a humanized interleukin-5 (IL-5) antagonist monoclonal antibody (IgG4 kappa) that is produced by recombinant DNA technology in murine myeloma non-secreting 0 (NS0) cells. IL-5 is a pro-inflammatory cytokine that is responsible for the growth and differentiation, recruitment, activation, and survival of eosinophils [FDA Label]. Elevated levels of eosinophils increase the risk for asthma exacerbations, including both allergic forms and nonallergic forms of asthma where eosinophilia is prominent. By targeting the IL-5 and disrupting its signalling pathways, reslizumab aims to inhibit eosinophil maturation and promote programmed cell death [A31578]. Asthma is a chronic respiratory disease that causes inflammation in the lungs with asthma attacks that lead to severe breathing difficulties. Patients often experience persistent or exacerbating symptoms overtime despite conventional first-line therapies available. Inflammation-predominant asthma, which is chatacterized by eosinophilic infiltration of airway mucosa and elevated levels of eosinophils in the blood, sputum and BAL fluid, is associated with an increased risk for recurrent exacerbation and asthma-related hospitalizations [A31579]. In four double-blind, randomized, placebo‑controlled trials in patients with severe asthma on currently available therapies, patients receiving reslizumab had fewer asthma attacks, and a longer time to the first attack compared to patients receiving placebo [FDA Label, A31579]. In addition, a significant improvement in lung function was seen, as measured by the volume of air exhaled by patients in one second [L1133]. Studies demonstrated that reslizumab was not effective in various asthma outcomes in patients without eosinophilia [A31577]. Reslizumab was developed by Teva Pharmaceuticals. Approved by the FDA in March 2016, reslizumab is marketed under the brand name Cinqair for intravenous injection. It is injected once every four weeks via intravenous infusion. Cinqair is indicated as an add-on maintenance therapy for adults with severe asthma with an eosinophilic phenotype. It is approved for patients who have a history of severe asthma attacks (exacerbations) despite receiving their current asthma medicines. Reslizumab is marketed as Cinqaero in Europe.
