Cinqair
Cinqair Uses, Dosage, Side Effects, Food Interaction and all others data.
Cinqair 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 . 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 .
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 . 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 . In addition, a significant improvement in lung function was seen, as measured by the volume of air exhaled by patients in one second . Studies demonstrated that reslizumab was not effective in various asthma outcomes in patients without eosinophilia .
Cinqair 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. Cinqair is marketed as Cinqaero in Europe.

Uses
Cinqair is an IL-5 antagonist used as an add-on maintenance treatment of patients with severe eosinophilic asthma in adults.
Indicated for the add-on maintenance treatment of patients with severe asthma aged 18 years and older with an eosinophilic phenotype.
Cinqair is also used to associated treatment for these conditions: Severe Eosinophilic Asthma
How Cinqair works
Cinqair an interleukin-5 (IL-5) antagonist (IgG4, kappa) that binds to IL-5 with a dissociation constant of 81 pM. IL-5 is a proinflammatory cytokine responsible for the terminal maturation of eosinophils and increases chemotaxis, endothelial adhesion, activation and survival of eosinophils. Eosinophils are known to play a central role in the pathophysiology of many patients with asthma; upon activation, eosinophils release leukotrienes, platelet activation factor, major basic protein, eosinophil cationic protein, eosinophil peroxidase, eosinophil-derived neurotoxin, and other cytokines that are cytotoxic to the bronchial epithelium and lead to airway inflammation and bronchospasm . IL-5 production is increased by upon activation of TH2 lymphocytes after antigen exposure and IL-5 stimulates the production and maturation of eosinophil precursors in the bone marrow . IL-5 promotes the growth and differentiation, recruitment, activation, and survival of eosinophils via interacting with the IL-5 receptor expressed on the eosinophil surface . Increased production and activation of eosinophils is especially prominent in nonallergic forms of asthma .
Cinqair is a humanized monoclonal antibody that occupies the region ERRR (glutamic acid, arginine, arginine, arginine) corresponding to amino acids 89–92 on IL-5, which is a region critical for its interaction with the IL-5 receptor on the eosinophil surface . By binding to IL-5 and disrupting its binding to the alpha chain of the IL-5 receptor complex, reslizumab inhibits the bioactivity of IL-5 and attenuates IL-5 signaling. Blocking of IL-5 signalling thereby reduces the production and survival of eosinophils and inhibits eosinophilic-driven inflammation.
Toxicity
Single doses of up to 732 mg have been administered intravenously to subjects in clinical trials without evidence of dose-related toxicities. There is no specific treatment for an overdose with reslizumab. If the event of an overdose, the patient should be treated supportively with appropriate monitoring as necessary .
Based on the findings of a 6-month bioassay, reslizumab showed no evidence of carcinogenicity. In a fertility study, administration of reslizumab to parental mice at doses up to 50 mg/kg (approximately 6 times the MRHD on an AUC basis) had no effects on male or female mating or fertility. The malignancy risk of reslizumab in humans with effects on tumor growth is not yet established .

Volume of Distribution
The approximate volume of distribution of reslizumab is 5L, suggesting minimal distribution to the extravascular tissues .
Elimination Route
The peak serum concentrations of reslizumab were typically observed at the end of the infusion with the serum concentrations gradually declining from the peak in a biphasic manner. Following multiple doses, serum concentrations of reslizumab accumulated approximately 1.5 to 1.9-fold. Interindividual variability in peak and overall exposure across healthy individuals, patients with asthma, and other populations in pharmacokinetic studies was around 20-30% . Systemic exposure to reslizumab appeared to be unaffected by the presence of treatment-emergent anti-reslizumab antibodies.
Half Life
The half-life is approximately 24 days .
Clearance
Cinqair clearance was approximately 7 mL/hour .
