What is Nucala?

Nucala is a prescription medicine:

    • for the add-on maintenance treatment of severe asthma in people 6 years of age and older whose asthma is not controlled with their current asthma medicines. Nucala helps prevent severe asthma attacks (exacerbations).
      Nucala is not used to treat sudden breathing problems that occur with asthma.
    • for the treatment of adults with eosinophilic granulomatosis with polyangiitis (EGPA). Nucala helps reduce symptoms and flares, and it may allow your healthcare provider to reduce your oral corticosteroid medicine.
    • for the treatment of people 12 years of age and older with hypereosinophilic syndrome (HES). Nucala helps reduce symptoms and prevent flares.

Medicines such as Nucala reduce blood eosinophils. Eosinophils are a type of white blood cells that may contribute to your disease.

  • It is unknown if Nucala is safe and effective in children with severe asthma under 6 years of age.
  • It is unknown if Nucala is safe and effective in children and adolescents with EGPA under 18 years of age.
  • It is unknown if Nucala is safe and effective in children with HES under 12 years of age.

Description

Mepolizumab is a humanized IL-5 antagonist monoclonal antibody. Mepolizumab is produced by recombinant DNA technology in Chinese hamster ovary cells. Mepolizumab has a molecular weight of approximately 149 kDa.

NUCALA for injection is a sterile, preservative-free, white to off-white, lyophilized powder in a single-dose vial for subcutaneous injection after reconstitution. Upon reconstitution with 1.2 mL of Sterile Water for Injection, USP, the resulting concentration is 100 mg/mL and delivers 1 mL [see Dosage and Administration (2.5)]. Each vial delivers 100 mg of mepolizumab, polysorbate 80 (0.67 mg), sodium phosphate dibasic heptahydrate (7.14 mg), and sucrose (160 mg), with a pH of 7.0.

The vial stopper is not made with natural rubber latex.

NUCALA injection is a sterile, preservative-free, clear to opalescent, colorless to pale yellow to pale brown solution for subcutaneous use.

NUCALA injection is supplied in a single-dose, 1-mL, prefilled autoinjector with a fixed 29-gauge, half-inch needle and in a single-dose, 1-mL, prefilled syringe with a fixed 29‑gauge, half-inch needle with a needle guard. Each 1 mL delivers 100 mg mepolizumab, citric acid monohydrate (0.95 mg), EDTA disodium dihydrate (0.019 mg), polysorbate 80 (0.20 mg), sodium phosphate dibasic heptahydrate (4.16 mg), and sucrose (120 mg), with a pH of 6.3.

NUCALA injection is supplied in a single-dose, 0.4-mL, prefilled syringe with a fixed 29-gauge, half-inch needle with a needle guard. Each 0.4 mL delivers 40 mg mepolizumab, citric acid monohydrate (0.38 mg), EDTA disodium dihydrate (0.0074 mg), polysorbate 80 (0.08 mg), sodium phosphate dibasic heptahydrate (1.66 mg), and sucrose (48 mg), with a pH of 6.3.

The prefilled autoinjector and prefilled syringe are not made with natural rubber latex.

Mechanism of Action

Mepolizumab is an IL-5 antagonist (IgG1 kappa). IL-5 is the major cytokine responsible for the growth and differentiation, recruitment, activation, and survival of eosinophils. Mepolizumab binds to IL-5 with a dissociation constant of 100 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 cell surface. Inflammation is an important component in the pathogenesis of asthma, CRSwNP, EGPA, and HES.

Multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) are involved in inflammation. Mepolizumab, by inhibiting IL-5 signaling, reduces the production and survival of eosinophils; however, the mechanism of mepolizumab action in asthma, CRSwNP, EGPA, and HES has not been definitively established.

  • You should inject Nucala under your skin (subcutaneously) into your thigh or stomach (abdomen). Also, a caregiver may give the injection in your upper arm.
  • If you miss a dose, inject a dose as soon as possible. Then continue (resume) your injection on your regular dosing schedule. If you do not notice that you have missed a dose until it is time for your next scheduled dose, then inject the next scheduled dose as planned. If you are not sure when to inject Nucala, call your healthcare provider.

What are the possible side effects of Nucala?

Nucala can cause serious side effects, including:
