Pfizer Inc. (NYSE:PFE) today announced top-line results from a Phase 4 study (CrisADe CARE 1) which showed that crisaborole ointment, 2%, was well-tolerated in children aged 3 months to less than 24 months with mild to moderate atopic dermatitis (AD), also known as eczema. The data from the trial are supportive of the primary study objective to examine the safety of crisaborole ointment, 2%, in this patient population, and are consistent with previous clinical trial experience.1 Crisaborole ointment, 2%, is currently approved in select countries for mild to moderate AD in patients two years of age and older.2,3,4,5

“This study reinforces our commitment to young AD patients worldwide who need more options,” said Michael Corbo, Chief Development Officer, Inflammation & Immunology, Pfizer Global Product Development. “These results add to the growing body of evidence that underscores the strength of data for crisaborole as a steroid-free, topical treatment option for people with mild to moderate atopic dermatitis. We look forward to discussing the data with regulatory authorities in the future.”

The primary endpoints of CrisADe CARE 1 were the number of patients with treatment-emergent adverse events (AEs) and severe adverse events (SAEs) and number of patients with clinically significant changes from baseline in height, weight, vital signs, electrocardiogram (ECG), and clinical laboratory parameters.

Detailed analyses of the study will be submitted for presentation at a future scientific meeting.

Crisaborole ointment, 2%, is a novel, steroid-free, topical phosphodiesterase (PDE4) inhibitor.6 It is approved in the U.S. and Canada as EUCRISA® (crisaborole ointment, 2%) and Israel and Australia as STAQUIS™ (crisaborole ointment, 2%) for mild to moderate atopic dermatitis (AD) in patients two years of age and older.2,3,4,5

About the CrisADe CARE 1 Study

The phase 4 crisaborole study (CrisADe CARE 1) was a 4-week, multicenter, open-label, single-arm study to evaluate the safety, pharmacokinetics (PK), and efficacy of crisaborole ointment, 2%, applied twice daily (BID) in 125 pediatric patients who were 3 months to less than 24 months of age with mild to moderate atopic dermatitis (AD) involving at least 5% treatable body surface area (%BSA), excluding the scalp. A cohort of 16 of the 125 subjects were included in a subgroup for PK assessment, with clinical diagnoses of moderate AD and a minimum of 35% treatable %BSA, excluding the scalp.1

About Atopic Dermatitis

AD is a chronic skin disease characterized by inflammation of the skin and skin barrier defects. Lesions of AD are characterized by erythema (redness), induration (hardening)/papulation (formulation of papules), and oozing/crusting.7,8

AD is one of the most common, chronic, relapsing childhood dermatoses, affecting up to 10% of adults and up to 20% of children worldwide.9,10 A total of 45% of all AD cases begin within the first 6 months of life, 60% begin during the first year, and 85% begin before 5 years of age.8,11 Approximately 50% of pediatric AD patients globally have recurrent symptoms into adolescence and adulthood.11,12
