DUPIXENT PROVIDED Rapid and sustained improvement in sense of smell, seen as early as week 2

Significantly Improved UPSIT Score vs Placebo at Week 24 (Key Secondary Endpoint) With Sustained Improvement Through Week 52 (Other Secondary Endpoint)1

Analysis of change at Week 52 was not multiplicity controlled; result is descriptive.



bChange in UPSIT score at Week 2 (LSM difference vs placebo: 5.36 [95% CI: 3.62, 7.10]).1


IMPROVEMENT AT WEEK 24 with DUPIXENT 300 mg Q2W + INCS (n=295, pooled DUPIXENT arms) (9.71 compared with a baseline score of 13.53) vs 6% worsening with placebo + INCS (n=153) (-0.81 compared with a baseline score of 13.78) (LSM difference: 10.52 [95% CI: 8.98, 12.07]) in Trial 21



  • 79% (n=228/287, pooled DUPIXENT arms) of patients taking DUPIXENT 300 mg Q2W + INCS had anosmia at baseline, which was reduced to 30% (n=84/280, pooled DUPIXENT arms) at Week 24 in Trial 21,2
    • There was almost no change with placebo: 76.7% (n=115/150 total patients) of patients taking placebo + INCS had anosmia at baseline, which was reduced to 76.6% (n=111/145 total patients) at Week 24 in Trial 21,2

University of Pennsylvania Smell Identification Test (UPSIT) score (range 0 to 40): higher score indicates improvement.

INCS, intranasal corticosteroids; LSM, least squares mean; Q2W, once every 2 weeks.

Important Safety
Information and Indications

CONTRAINDICATION: DUPIXENT is contraindicated in patients with known hypersensitivity to dupilumab or any of its excipients.


Hypersensitivity: Hypersensitivity reactions, including generalized urticaria, rash, erythema nodosum, erythema multiforme, anaphylaxis, and serum sickness or serum sickness-like reactions, were reported in <1% of subjects who received DUPIXENT in clinical trials. If a clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue DUPIXENT.

Conjunctivitis and Keratitis: Conjunctivitis occurred more frequently in subjects with chronic rhinosinusitis with nasal polyposis who received DUPIXENT. There were no cases of keratitis reported in the CRSwNP development program. Among asthma subjects, the frequencies of conjunctivitis and keratitis were similar between DUPIXENT and placebo. Advise patients to report new onset or worsening eye symptoms to their healthcare provider.

Eosinophilic Conditions: Patients being treated for asthma may present with serious systemic eosinophilia sometimes presenting with clinical features of eosinophilic pneumonia or vasculitis consistent with eosinophilic granulomatosis with polyangiitis (EGPA), conditions which are often treated with systemic corticosteroid therapy. These events may be associated with the reduction of oral corticosteroid therapy. Physicians should be alert to vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients with eosinophilia. Cases of eosinophilic pneumonia were reported in adult patients who participated in the asthma development program and cases of vasculitis consistent with EGPA have been reported with DUPIXENT in adult patients who participated in the asthma development program as well as in adult patients with co-morbid asthma in the CRSwNP development program. A causal association between DUPIXENT and these conditions has not been established.

Acute Asthma Symptoms or Deteriorating Disease: Do not use DUPIXENT to treat acute asthma symptoms, acute exacerbations, acute bronchospasm or status asthmaticus. Patients should seek medical advice if their asthma remains uncontrolled or worsens after initiation of DUPIXENT.

Risk Associated with Abrupt Reduction of Corticosteroid Dosage: Do not discontinue systemic, topical, or inhaled corticosteroids abruptly upon initiation with DUPIXENT. Reductions in corticosteroid dose, if appropriate, should be gradual and performed under the direct supervision of a physician. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy.

Patients with Co-Morbid Asthma: Advise patients with CRSwNP who have co-morbid asthma not to adjust or stop their asthma treatments without consultation with their physicians.

Parasitic (Helminth) Infections: It is unknown if DUPIXENT will influence the immune response against helminth infections. Treat patients with pre-existing 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. Helminth infections (5 cases of enterobiasis and 1 case of ascariasis) were reported in pediatric patients 6 to 11 years old in the pediatric asthma development program.


  • Asthma: The most common adverse reactions (incidence ≥1%) are injection site reactions, oropharyngeal pain, and eosinophilia.
  • Chronic rhinosinusitis with nasal polyposis: The most common adverse reactions (incidence ≥1%) are injection site reactions, eosinophilia, insomnia, toothache, gastritis, arthralgia, and conjunctivitis.

DRUG INTERACTIONS:  Avoid use of live vaccines in patients treated with DUPIXENT.


  • Pregnancy: A pregnancy exposure registry monitors pregnancy outcomes in women exposed to DUPIXENT during pregnancy. To enroll or obtain information call 1‑877‑311‑8972 or go to https://mothertobaby.org/ongoing-study/dupixent/. Available data from case reports and case series with DUPIXENT use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Human IgG antibodies are known to cross the placental barrier; therefore, DUPIXENT may be transmitted from the mother to the developing fetus.
  • Lactation: There are no data on the presence of DUPIXENT in human milk, the effects on the breastfed infant, or the effects on milk production. Maternal IgG is known to be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for DUPIXENT and any potential adverse effects on the breastfed child from DUPIXENT or from the underlying maternal condition.

Please see accompanying full Prescribing Information.


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

Chronic rhinosinusitis with nasal polyposis (CRSwNP): DUPIXENT is indicated as an add-on maintenance treatment in adult patients with inadequately controlled CRSwNP.
