PFIZER RECEIVES FDA APPROVAL FOR EUCRISATM (CRISABOROLE), A NOVEL NON-STEROIDAL TOPICAL OINTMENT FOR MILD TO MODERATE ATOPIC DERMATITIS (ECZEMA)
EUCRISA Approved for Patients 2 Years of Age and Older
First Prescription Treatment Approved for Eczema in More than a Decade
Pfizer Inc. (NYSE:PFE) announced today that the U.S. Food and Drug Administration (FDA) approved EUCRISATM (crisaborole) ointment 2%, a novel non-steroidal topical phosphodieterase-4 (PDE-4) inhibitor for the treatment of mild to moderate atopic dermatitis (AD) in patients two years of age and older.1 AD, often called eczema, is a chronic condition impacting nearly 18 million children and adults in the United States.2 Approximately 90 percent of people living with AD have the mild to moderate form of the condition.3
“The approval of EUCRISA is great news for the children and adults suffering from mild to moderate eczema, a community that has not had a new prescription treatment for more than 10 years,” said Albert Bourla, Group President, Pfizer Innovative Health. “This is also an important milestone for Pfizer as we continue to build on our heritage in Inflammation and Immunology by offering innovative treatment options to patients who need them.”
EUCRISA is the first and only non-steroidal topical monotherapy that inhibits the PDE-4 enzyme in the skin. Overactive PDE-4 has been shown to contribute to the signs and symptoms of AD.4 The specific mechanism of action of crisaborole in AD is not well defined.1
“I’m delighted to have a new option for my patients with mild to moderate atopic dermatitis,” said Amy Paller, M.D., Walter J. Hamlin Professor and Chair of Dermatology, Professor of Pediatrics, Northwestern University Feinberg School of Medicine, a clinical trial investigator. “The results seen in these pivotal Phase 3 studies show the efficacy and safety of EUCRISA as a steroid-free treatment option for people as young as two living with mild to moderate atopic dermatitis.”
SELECTED IMPORTANT SAFETY INFORMATION
CONTRAINDICATION: EUCRISA is contraindicated in patients with known hypersensitivity to crisaborole or any component of the formulation.
EUCRISA TRIAL RESULTS
The approval of EUCRISA is based on a clinical development program including the results of two large, identical, multicenter, randomized, double-blind, parallel-group, vehicle- controlled (non-medicated ointment) trials (Trials 1 and 2) that treated 1,522 patients with mild to moderate AD between the ages of two and 79.1 At baseline, 38.5% of the subjects had an Investigator’s Static Global Assessment (ISGA) score of 2 (mild), and 61.5% had an ISGA score of 3 (moderate). The ISGA score includes erythema (redness), induration (hardening)/papulation (formation of papules), and oozing/crusting on a severity scale of 0 to 4.
In both trials, subjects were randomized 2:1 to receive EUCRISA or vehicle (non-medicated ointment) applied to skin with signs and symptoms of AD twice daily for 28 days.1 The primary efficacy endpoint was success in ISGA at day 29, defined as the proportion of patients achieving an ISGA score of 0 (clear) or 1 (almost clear) with at least a 2-grade improvement from baseline. These data showed EUCRISA to be an effective treatment that achieved statistically significant results versus vehicle for the primary efficacy endpoint in adults and children two years of age and older [32.8% versus 25.4% (P=0.038) for Trial 1 and 31.4% versus 18.0% (P<0.001) for Trial 2].1,3 Efficacy results were seen in some patients as early as day eight (first post-baseline assessment), with 13.4% of EUCRISA patients achieving success in ISGA versus 4.5% with vehicle in Trial 1 and 15.9% EUCRISA versus 6.3% vehicle in Trial 2.1,5,6
In these studies, the adverse reaction reported by more than 1% of EUCRISA patients was pain at the application site, such as stinging or burning [4% (N=45)] versus vehicle [1% (N=6)]. The rate of study discontinuation due to adverse reactions was the same in the EUCRISA group versus vehicle (1.2%).3
“After many years without new therapies, this is an exciting day for those living with mild to moderate eczema and their caregivers,” said Julie Block, President and Chief Executive Officer of the National Eczema Association.
INDICATION & IMPORTANT SAFETY INFORMATION
EUCRISA is indicated for topical treatment of mild to moderate atopic dermatitis in patients 2 years of age and older.
EUCRISA is contraindicated in patients with known hypersensitivity to crisaborole or any component of the formulation.
WARNINGS AND PRECAUTIONS
Hypersensitivity reactions, including contact urticaria, have occurred in patients treated with EUCRISA and should be suspected in the event of severe pruritus, swelling and erythema at the application site or at a distant site. Discontinue EUCRISA immediately and initiate appropriate therapy if signs and symptoms of hypersensitivity occur.
The most common adverse reaction occurring in = 1% in subjects in clinical trials was application site pain, such as burning or stinging.
The full results for these trials were published in July 2016, in the Journal of the American Academy of Dermatology.
