Frequently Asked Questions

DUPIXENT has a unique mechanism of action. It is the only dual inhibitor of IL-4 and IL-13 signaling, two of the key sources of local and systemic type 2 inflammation in asthma. GINA guidelines define type 2 inflammation as an immune response identified in part by 1 or more biomarkers. The mechanism of dupilumab action has not been definitively established.^1-3

DUPIXENT is indicated as an add-on maintenance treatment of adult and pediatric patients aged 6 years and older with moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid dependent asthma.
Limitations of Use: DUPIXENT is not indicated for the relief of acute bronchospasm or status asthmaticus.¹

Up to 84% of adult asthma patients present with type 2 inflammation, which can be both local and systemic. DUPIXENT targets both IL-4 and IL-13 signaling, two of the key sources of type 2 inflammation in asthma. The mechanism of dupilumab action has not been definitively established.^1,2,4,5

DUPIXENT is indicated as an add-on maintenance treatment of adult and pediatric patients aged 6 years and older with moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid dependent asthma.
Limitations of Use: DUPIXENT is not indicated for the relief of acute bronchospasm or status asthmaticus.¹

DUPIXENT is the only dual inhibitor of IL-4 and IL-13 signaling. It is the only FDA-approved biologic indicated for OCS-dependent asthma patients. The mechanism of dupilumab action has not been definitively established.¹

DUPIXENT is indicated as an add-on maintenance treatment of adult and pediatric patients aged 6 years and older with moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid dependent asthma.

DUPIXENT is a GINA-recognized treatment option for children with asthma aged 6-11 years and has a demonstrated safety profile.^1,3,6

DUPIXENT is not an immunosuppressant and avoids broad immunosuppression. It is unknown if DUPIXENT will influence the immune response against helminth infections. Treat patients with preexisting helminth infections before initiating therapy with DUPIXENT. If patients become infected while receiving treatment with DUPIXENT and do not respond to anti-helminth treatment, discontinue treatment with DUPIXENT until the infection resolves. DUPIXENT is a human monoclonal antibody that inhibits the signaling of IL-4 and IL-13, two of the key cytokines that contribute to type 2 inflammation in asthma. The mechanism of dupilumab action has not been definitively established.¹

In the DUPIXENT pivotal clinical trials, the most common adverse reactions (incidence ≥1%) in patients with asthma were injection site reactions, oropharyngeal pain, and eosinophilia. The safety profile of DUPIXENT in children 6-11 years of age with moderate-to-severe asthma through Week 52 was similar to the safety profile from studies in adult and pediatric subjects 12 years of age and older with moderate-to-severe asthma with the addition of helminth infections. Helminth infections were reported in 2.2% (6 subjects) in the DUPIXENT group and 0.7% (1 subject) in the placebo group. The majority of cases were enterobiasis, reported in 1.8% (5 subjects) in the DUPIXENT group and none in the placebo group. There was 1 case of ascariasis in the DUPIXENT group. All helminth infection cases were mild to moderate, and subjects recovered with anti-helminth treatment without DUPIXENT treatment discontinuation.¹

In addition to moderate-to-severe eosinophilic or OCS-dependent asthma, DUPIXENT is indicated in other disease states.¹

QUEST (12+ years)

DUPIXENT offers rapid breathing relief patients can feel as early as Week 2. Approximately 72% of the total FEV₁ improvement (470 mL improvement at Week 52 from baseline FEV₁ of 1.78 L) was seen at Week 2 in patients taking DUPIXENT 200 mg Q2W + SOC (n=264) (baseline blood EOS ≥300 cells/μL, QUEST, secondary endpoint).^1,7,8

A 320 mL improvement from baseline in pre-bronchodilator FEV₁ was seen at Week 12 with DUPIXENT 200 mg Q2W + SOC (n=631) vs 180 mL with placebo + SOC (n=317) (LSM difference: 140 mL [95% CI: 80, 190 mL]) (ITT population, QUEST, primary endpoint).^1,6

DRI12544 (18+ years), QUEST (12+ years), VOYAGE (6-11 years)

The most common adverse reactions from the DUPIXENT asthma trials were injection site reactions,^l oropharyngeal pain, and eosinophilia.^m These adverse reactions occurred in ≥1% of patients receiving DUPIXENT + SOC and at a higher rate than in patients receiving placebo + SOC in DRI12544 and QUEST (6-month safety pool).¹

The safety profile of DUPIXENT through Week 52 was similar to the safety profile from studies in adult and pediatric subjects 12 years of age and older with moderate-to-severe asthma with the addition of helminth infections.¹

DRI12544 (18+ years), QUEST (12+ years), VENTURE (12+ years), VOYAGE (6-11 years)

Subjects enrolled in DRI12544 and QUEST were required to have a history of at least 1 severe asthma exacerbation in the year prior to trial entry. A severe asthma exacerbation was defined as deterioration of asthma requiring the use of systemic corticosteroids for at least 3 days or asthma-related hospitalization or emergency department visit requiring systemic corticosteroids.¹

Subjects enrolled in DRI12544 and QUEST were receiving the SOC for their moderate-to-severe asthma. Those enrolled in VENTURE required dependence on daily OCS in addition to regular use of high-dose ICS plus a minimum of 1 and up to 2 additional controller medications as SOC for their asthma. In all 3 trials, enrollment was unrestricted by minimum baseline blood eosinophil count. In QUEST and VENTURE, subjects with baseline blood eosinophil levels >1500 cells/μL (<1.3%) were excluded.^1,10

Subjects enrolled in VOYAGE were children (6-11 years) with uncontrolled moderate-to-severe asthma on an SOC of medium-dose ICS with a second controller medication or high-dose ICS with or without a second controller medication. Subjects were evaluated in 2 prespecified populations: blood EOS ≥300 cells/μL and blood EOS ≥150 cells/μL or FeNO ≥20 ppb (eosinophilic phenotype).⁶

DUPIXENT is an injectable medicine that is administered by subcutaneous injection. A patient may self-inject DUPIXENT—or a caregiver may administer DUPIXENT—after training has been provided by a healthcare provider on proper subcutaneous injection technique using the pre-filled syringe or pen. In children 12 years of age and older, it is recommended that DUPIXENT be administered under the supervision of an adult. In children 6 to less than 12 years of age, DUPIXENT should be given by a caregiver.¹

If your patient is 12+ years and has moderate-to-severe asthma characterized by an eosinophilic phenotype, DUPIXENT is available in 200 mgⁿ and 300 mg^o doses. The 200 mg treatment, given every 2 weeks, has an initial loading dose of 400 mg (2 x 200 mg pre-filled pens or syringes), and the 300 mg treatment, given every 2 weeks, has an initial loading dose of 600 mg (2 x 300 mg pre-filled pens or syringes).¹

If your patient is 12+ years and has OCS-dependent asthma or comorbid moderate-to-severe atopic dermatitis or is an adult with comorbid chronic rhinosinusitis with nasal polyposis, the recommended dose is an initial loading dose of 600 mg (2 x 300 mg pre-filled pens or syringes) followed by every-2-week dosing of a 300 mg pre-filled pen or syringe.¹

If your patient is aged 6-11 years with uncontrolled moderate-to-severe asthma for which DUPIXENT is indicated, the dosing is weight-based. For children weighing 15 kg^p to less than 30 kg, the recommended dose is 300 mg given every 4 weeks via a pre-filled pen or syringe. For children weighing 30 kg^q or more, the recommended dose is 200 mg given every 2 weeks via a pre-filled pen or syringe. For children aged 6-11 years with asthma and comorbid moderate-to-severe atopic dermatitis, follow the recommended dosage for atopic dermatitis, which includes an initial loading dose.¹

The pre-filled syringe and pre-filled pen come with their own set of specific instructions and guidelines for administration. After choosing your preferred method of treatment, it is important to provide proper training to patients and/or caregivers on the preparation and administration of DUPIXENT prior to use to ensure each step is followed correctly.

It is recommended that children 12 years of age and older administer DUPIXENT under the supervision of an adult. In children 6 to less than 12 years of age, DUPIXENT should be given by a caregiver.¹

Provide proper training to patients and/or caregivers on the preparation and administration of DUPIXENT prior to use according to the Instructions for Use.¹

Advise patients to follow sharps disposal recommendations after administration of DUPIXENT. Patients and/or caregivers should read the appropriate Instructions for Use prior to injecting.¹

Download the full Instructions for Use below.

If a dose is missed, instruct the patient to administer the injection within 7 days from the missed dose and then resume the original schedule. If the missed dose is not administered within 7 days, instruct the patient to wait until the next dose on the original schedule (for an every-other-week dose) or administer the dose, starting a new schedule based on this date (for an every-4-week dose).¹

DUPIXENT should be refrigerated at 36 °F to 46 °F (2 °C to 8 °C) in the original carton to protect from light. If necessary, DUPIXENT may be kept at room temperature up to 77 °F (25 °C) for a maximum of 14 days. Do not store above 77 °F (25 °C). After removal from the refrigerator, DUPIXENT must be used within 14 days or discarded.¹

Do not expose DUPIXENT to heat or direct sunlight. Do NOT freeze. Do NOT shake.¹
