Dupixent Pre-filled Pen Uses, Dosage, Side Effects, Food Interaction and all others data.
Dupixent Pre-filled Pen is a fully human monoclonal antibody of the immunoglobulin G4 subclass that binds to the interleukin-4 (IL-4) receptor, inhibiting the receptor signaling pathways. As an interleukin-4 receptor alpha antagonist, dupilumab inhibits the signaling of pro-inflammatory cytokines, called interleukins (IL), that induce inflammatory and immunological reactions in several atopic or allergic conditions, such as eczema, allergic reaction, and rhinosinusitis. Dupixent Pre-filled Pen was generated by recombinant DNA technology in Chinese Hamster Ovary cell suspension culture.
Dupixent Pre-filled Pen is commonly marketed as Dupixent®, which is available as a formulation for subcutaneous injection. It was first approved by the FDA in 2017 for patients 12 and older with eczema or atopic dermatitis. Dupixent Pre-filled Pen is also approved by Health Canada for the same indication and the European Commission for use in atopic dermatitis as well as severe asthma with type 2 inflammation. It is the first biologic therapy to have been approved for the treatment of adult patients with moderate-to-severe AD in the EU and USA. In 2018, FDA approved the use of dupilumab as an add-on maintenance treatment for patients 12 years and older with moderate-to-severe eosinophilic asthma or with oral corticosteroid-dependent asthma. In June 2019, dupilumab was also approved by the FDA as a treatment for inadequately controlled chronic rhinosinusitis with nasal polyps in adult patients. Dupixent Pre-filled Pen is currently under investigations for potential therapeutic use in diseases driven by allergic reactions or type 2 inflammation, such as pediatric atopic dermatitis, eosinophilic esophagitis, and chronic obstructive pulmonary disease. It is also being studied in combination with another antibody that which targets IL-33.
Dupixent Pre-filled Pen is an recombinant human IgG4 antibody to the IL-4 receptor that works by inhibiting the activation of certain pro-inflammatory cytokines that are implicated in the pathophysiology of several allergic and atopic conditions, including asthma, chronic rhinosinusitis with nasal polyps, and food and environmental allergies. In vivo, dupilumab was shown to reduce the levels of type 2 inflammatory biomarkers associated with atopic dermatitis, such as thymus and activation-regulated chemokine (TARC/CCL17), total serum IgE, allergen-specific IgE, and lactate dehydrogenase (LDH). A decrease in the levels of biomarkers of asthma, such as FeNO, eotaxin-3, IgE, periostin, and eotaxin-3 (CCL26) was also observed. Since dupilumab works to suppress the immune response, it is proposed that it may influence the immune response against some infections, such as helminth infections, by inhibiting IL-4/IL-13 signaling. It is advised that infections are appropriately treated until resolved before initiating dupilumab therapy.

Uses
Dupixent Pre-filled Pen is a monoclonal antibody used to treat moderate to severe atopic dermatitis, asthma, and nasal polyps accompanied by chronic rhinosinusitis in adolescents and adults.
Dupixent Pre-filled Pen indicated, as monotherapy or in combination with topical corticosteroids, for the treatment of patients aged 12 years and older with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.
Indicated as an add-on maintenance treatment in patients with moderate-to-severe asthma aged 12 years and older with an eosinophilic phenotype or with oral corticosteroid dependent asthma. It is not indicated for the relief of acute bronchospasm or status asthmaticus.
Indicated for the treatment of nasal polyps accompanied by inadequately controlled chronic rhinosinusitis in adult patients.
Dupixent Pre-filled Pen is also used to associated treatment for these conditions: Moderate to Severe Asthma, Severe Atopic Dermatitis, Moderate Atopic dermatitis
How Dupixent Pre-filled Pen works
Type 2 inflammatory processes in various allergic and atopic conditions, such as asthma and atopic diseases, involve the type 2 helper T-cell (Th2) immunity. Upregulation of this Type 2/Th2 pathway is commonly observed in other inflammatory conditions and the activation of Th2 cells is linked to the production of Th2-associated cytokines, such as interleukin (IL) 4, IL-5, IL-9, and IL-13. IL-4 and IL-13 play a central role in inducing inflammatory conditions such as allergic rhinitis, asthma, and atopic dermatitis, by regulating Type 2 inflammation and immune function. These inflammatory cytokines work by modulating gene expression downstream of receptor signalling, regulating Th2 cell differentiation, and activating inflammatory cells such as mast cells and macrophages.
There are two types of receptors for IL-4: the type 1 receptor, which is composed of the IL-4 chain (IL-4Rα) and a γ chain (γC), and the type 2 receptor, which is composed of the IL-4Rα chain and the α1 chain of the IL-13 receptor (IL-13Rα1). Essentially, IL‐4Rα is a component shared by the IL‐4 and IL-13 receptor complexes and is ubiquitously expressed on both innate and adaptive immune cells to promote the signaling of IL-4 and IL-13. The type I receptor is primarily expressed on lymphocytes and controls Th2-cell differentiation, whereas the type II receptor is mostly found across resident and myeloid cells. Dupixent Pre-filled Pen is a fully human monoclonal antibody directed against IL‐4Rα to inhibit the signalling of IL‐4 and IL‐13. Dupixent Pre-filled Pen inhibits IL-4 signalling via the Type I receptor (IL-4Rα/γc), and both IL-4 and IL-13 signaling through the Type II receptor (IL-4Rα/IL-13Rα). It ultimately downregulates type-2 immunity.
Toxicity
There is limited data on the overdose of dupilumab. As there is no specific treatment for dupilumab, close monitoring of the patient with appropriate symptomatic treatment is advised in case of suspected overdosage.[]

Volume of Distribution
The estimated volume of distribution is 4.8 ± 1.3 L.
Elimination Route
The Cmax following administration of a single subcutaneous dose of 600 mg or 400 mg of dupilumab were 70.1 ± 24.1 mcg/mL or 41.8 ± 12.4 mcg/mL, respectively. The Tmax ranged from 3 to 7 days following administration of a single subcutaneous dose ranging from 75 to 600 mg. Following a subcutaneous dose, the absolute bioavailability of dupilumab ranged between 61% and 64% in patients with atopic dermatitis or asthma.
In clinical trials, the steady-state concentrations were reached by week 16 following the administration of 600 mg starting dose and 300 mg dose every other week. At these concentrations, the mean trough concentrations ranged from 60.3 ± 35.1 mcg/mL to 79.9 ± 41.4 mcg/mL for 300 mg dose and from 29.2 ± 18.7 to 36.5 ± 22.2 mcg/mL for 200 mg dose administered every other week.
Half Life
There is limited human data on the half-life of dupilumab. In single-dose pharmacokinetic studies, the mean half-life of dupilumab following intravenous or subcutaneous administration ranged from 4.8 to 7 days in rats and 11.7 to 20.5 days in cynomolgus monkeys. In these studies, the mean half-life was comparable was comparable following intravenous and subcutaneous administration.
Clearance
There is limited data on the clearance of dupilumab.
Elimination Route
Being a monoclonal antibody, dupilumab is not expected to undergo significant renal elimination. It is proposed that dupilumab is eliminated via parallel linear and nonlinear pathways. At higher concentrations, dupilumab is primarily cleared through a non-saturable proteolytic pathway. At lower concentrations, it undergoes a non-linear saturable IL-4R α target-mediated elimination.
