aPooled analysis of Trials 1, 2, and 4 (phase 2 dose-ranging study).

bAnalysis of Trial 3 in which subjects were on background TCS therapy.

cDUPIXENT 600 mg at Week 0, followed by 300 mg every 2 weeks.

dConjunctivitis cluster includes conjunctivitis, allergic conjunctivitis, bacterial conjunctivitis, viral conjunctivitis, giant papillary conjunctivitis, eye irritation, and eye inflammation.

eKeratitis cluster includes keratitis, ulcerative keratitis, allergic keratitis, atopic keratoconjunctivitis, and ophthalmic herpes simplex.

fOther herpes simplex virus infection cluster includes herpes simplex, genital herpes, herpes simplex otitis externa, and herpes virus infection, but excludes eczema herpeticum.

  • Most patients experiencing conjunctivitis recovered or were recovering during the treatment period1

Select adverse events in the 52-week trial in adults

  • The rate of serious adverse events with DUPIXENT + TCS was comparable to placebo + TCS (4% vs 5%, respectively)2
  • Keratitis was reported in 4% of the DUPIXENT + TCS group and in 0% of the placebo + TCS group1
  • Conjunctivitis was reported in 16% of the DUPIXENT + TCS group and in 9% of the placebo + TCS group1
Fewer patients treated with DUPIXENT developed skin infections compared with placebo2
  • 11% vs 18% of adults in Trial 3, respectively

Discontinuation rates in adults due to adverse events with DUPIXENT with or without TCS were comparable to those with placebo1
  • 1.9% of patients treated with DUPIXENT discontinued treatment through Week 16 vs 1.9% of patients treated with placebo through Week 16 (Trials 1, 2, and 4)
  • Similar discontinuation rates occurred at Week 52 in Trial 3 (1.8% with DUPIXENT + TCS vs 7.6% with placebo + TCS)

Patients should discontinue DUPIXENT if a clinically significant hypersensitivity reaction occurs or until a parasitic (helminth) infection resolves in a patient who does not respond to anti-helminth treatment.1

Avoid use of live vaccines in patients treated with DUPIXENT1


Safety data collected from three phase 3 trials and one dose-ranging trial (Trial 4) (N=2304)1,2

  • 49% had allergic rhinitis
  • 37% had food allergy
  • 27% had allergic conjunctivitis

Safety and efficacy of DUPIXENT have not been established in the treatment of these conditions.1

DUPIXENT clinical trials included adult patients with a history of systemic steroid use2

Trial 3 (history of systemic steroid use)

38%
of adult patients treated with DUPIXENT + TCS (n=110) or placebo + TCS (n=315) had a history of using
systemic steroids

Trial 3 (systemic steroid rescue medication use)

8%
of adult patients required systemic steroids as rescue medication while on DUPIXENT + TCS vs 11% with placebo + TCS through Week 52 during Trial 3g

In addition to systemic steroids, other agents were used as rescue treatment.2

  • Overall, in adult patients through Week 52, 16% of DUPIXENT + TCS patients required rescue therapy vs 38% of placebo + TCS patients
In these clinical trials, a numerically smaller proportion of DUPIXENT patients required systemic steroids as a rescue medication vs placebo + TCS2

g These patients were considered nonresponders and their double-blind study medication was temporarily discontinued.2

Important Safety
Information and Indication

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

WARNINGS AND PRECAUTIONS

Hypersensitivity: Hypersensitivity reactions, including generalized urticaria, rash, erythema nodosum, 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 and keratitis occurred more frequently in atopic dermatitis subjects who received DUPIXENT. Conjunctivitis was the most frequently reported eye disorder. Most subjects with conjunctivitis or keratitis recovered or were recovering during the treatment period. Advise patients to report new onset or worsening eye symptoms to their healthcare provider.

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.

Atopic Dermatitis Patients with Comorbid Asthma: Advise patients 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.

ADVERSE REACTIONS: The most common adverse reactions (incidence ≥1% at Week 16) in adult patients with atopic dermatitis are injection site reactions, conjunctivitis, blepharitis, oral herpes, keratitis, eye pruritus, other herpes simplex virus infection, and dry eye. The safety profile in children and adolescents through Week 16 was similar to that of adults with atopic dermatitis. In an open-label extension study, the long-term safety profile of DUPIXENT in adolescents and children observed through Week 52 was consistent with that seen in adults with atopic dermatitis.

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

USE IN SPECIFIC POPULATIONS

  • Pregnancy: There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to DUPIXENT during pregnancy. Healthcare providers and patients may call 1-877-311-8972 or go to https://mothertobaby.org/ongoing-study/dupixent/ to enroll in or obtain information about the registry. 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.

Indication

DUPIXENT is indicated for the treatment of patients aged 6 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. DUPIXENT can be used with or without topical corticosteroids.
