AbbVie Presents New Late-Breaking Phase 2b Data on Upadacitinib in Atopic Dermatitis at the 2018 American Academy of Dermatology Annual Meeting

NORTH CHICAGO, Ill., Feb. 17, 2018 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global research and development-based biopharmaceutical company, today presented new positive results from a Phase 2b dose-ranging study evaluating upadacitinib, an investigational, once-daily oral JAK1-selective inhibitor, in adult patients with moderate to severe atopic dermatitis. These results were featured during the "Late-Breaking Research: Clinical Trials" session at the 2018 American Academy of Dermatology (AAD) Annual Meeting in San Diego. Upadacitinib is not approved by regulatory authorities and its safety and efficacy have not been established.

In September of 2017, AbbVie announced positive top-line results from this Phase 2b study, including an evaluation of the primary endpoint – mean percent change in Eczema Area and Severity Index (EASI) at week 16 versus placebo.¹ The press release is available here.

In today's presentation, across all doses (30/15/7.5 mg once-daily), additional exploratory results showed significant reduction of select symptoms of atopic dermatitis in upadacitinib patients, including reduction in itch (pruritus) at week 1 and improvement in the extent and severity of skin lesions at week 2.¹

"Patients living with atopic dermatitis are seeking relief from the intense itching and skin lesions - which can have a profound impact," said Emma Guttman-Yassky, M.D., Ph.D., Professor of Dermatology and Immunology, Icahn School of Medicine at Mount Sinai Medical Center and lead study investigator. "For this patient population, given the severity of their disease and available targeted therapies, additional options are needed."

Evaluation of Signs and Severity (Eczema Area and Severity Index)

• In an exploratory analysis, results at week 2 of treatment with upadacitinib showed all dose groups (30/15/7.5 mg once-daily) achieved significant improvement in extent and severity of atopic dermatitis, as measured by the mean percent change in Eczema Area and Severity Index (EASI) score.¹

Evaluation of Reduction in Itch (Pruritus)

• In an exploratory analysis, results at week 1 showed reduction in itch in patients treated with upadacitinib, as measured by the pruritus numerical rating scale (NRS).¹

The most common adverse events were upper respiratory tract infection, atopic dermatitis worsening and acne.¹ Serious adverse events across treatment groups occurred in 0/1/2 patients in the 30/15/7.5 mg groups compared to 1 patient on placebo.¹ No herpes zoster, malignancies, deaths or cases of pulmonary embolism (PE) or deep vein thrombosis (DVT) occurred in the first 16 weeks of this Phase 2b study.¹

"This study showed that upadacitinib significantly reduced itch and improved skin lesions supporting its potential to be a meaningful treatment option for patients," said Marek Honczarenko, M.D., Ph.D., vice president, immunology development, AbbVie. "We strive to make a remarkable impact on patients' lives and we look forward to advancing this development program into registration-enabling studies this year."

About Atopic Dermatitis
Atopic dermatitis, a chronic inflammatory skin disease, is characterized by skin erosion, oozing and crusting, redness, intense itching and dry skin.¹⁰ Symptoms can appear as a rash on the skin, or the skin may become thickened and leathery.¹¹

About the Phase 2b Upadacitinib Study¹
This dose-ranging study is an ongoing 88-week Phase 2b, randomized, double-blind, parallel-group, placebo-controlled multicenter study designed to evaluate the safety and efficacy of upadacitinib in adult patients with moderate to severe atopic dermatitis not adequately controlled by topical treatments, or for whom topical treatments were not medically advisable. In Period 1, subjects were randomized in a 1:1:1:1 ratio to one of four treatment groups (three dosing groups, 30/15/7.5 mg once-daily, and one placebo group) for 16 weeks. The primary endpoint of the study was mean percentage change from baseline in Eczema Area and Severity Index (EASI) score at 16 weeks in comparison with placebo. Secondary endpoints included proportion of patients achieving EASI 90, EASI 75, an Investigator Global Assessment (IGA) of 0 or 1 and percent change in pruritus/itch numerical rating scale from day 1 (baseline) to week 16 in comparison with placebo. More information on this trial can be found at www.clinicaltrials.gov (NCT02925117).

About Upadacitinib
Discovered and developed by AbbVie, upadacitinib is an investigational oral agent engineered to selectively inhibit JAK1, which plays an important role in the pathophysiology of immune-mediated disorders.^2,3 Phase 3 trials of upadacitinib in rheumatoid arthritis, psoriatic arthritis and Crohn's disease are ongoing.^4-6 Upadacitinib is also being evaluated as a potential treatment for ankylosing spondylitis.⁷ AbbVie plans to begin registration-enabling studies in atopic dermatitis, ulcerative colitis and giant cell arteritis this year.^8,9

In January 2018, the U.S. Food and Drug Administration granted Breakthrough Therapy Designation for upadacitinib in adult patients with moderate to severe atopic dermatitis who are candidates for systemic therapy. Breakthrough Therapy Designation is intended to expedite the development and review of medicines with preliminary clinical evidence that indicate that the investigational treatment may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints.¹²

Upadacitinib is an investigational oral agent and is not approved by regulatory authorities. Safety and efficacy have not been established.
