Reslizumab

What is Reslizumab?

Reslizumab (CINQAIR) is an interleukin-5 antagonist monoclonal antibody (IgG4 kappa) used therapeutically to reduce allergic symptoms of asthma in patients with an eosinophilic phenotype.

What are the uses of this medicine?

This medicine is used for maintenance treatment of patients with severe asthma aged 18 years and older with an eosinophilic phenotype.

Limitations of Use:

• CINQAIR is not indicated for treatment of other eosinophilic conditions.
• CINQAIR is not indicated for the relief of acute bronchospasm or status asthmaticus.

How does this medicine work?

• Reslizumab is an interleukin-5 antagonist (IgG4, kappa). IL-5 is the major cytokine responsible for the growth and differentiation, recruitment, activation, and survival of eosinophils.
• Reslizumab binds to IL-5 with a dissociation constant of 81 pM, inhibiting the bioactivity of IL-5 by blocking its binding to the alpha chain of the IL-5 receptor complex expressed on the eosinophil surface.
• Reslizumab, by inhibiting IL-5 signaling, reduces the production and survival of eosinophils; however, the mechanism of reslizumab action in asthma has not been definitively established.

Who Should Not Use this medicine ?

This medicine cannot be used in patients with:

• hypersensitivity to reslizumab or any of its excipients

What drug interactions can this medicine cause?

• No formal clinical drug interaction studies have been performed with CINQAIR.

• Observe the patient over the infusion and for an appropriate period of time following infusion.
• Upon completion of the infusion, flush the intravenous administration set with 0.9% Sodium Chloride Injection, USP to ensure that all CINQAIR has been administered.
