RINVOQ™ (upadacitinib) Monotherapy Shows Improvement in Skin Clearance and Itch in First Phase 3 Study for Atopic Dermatitis

– Top-line results from a Phase 3 study evaluating RINVOQ in moderate to severe atopic dermatitis in adults and adolescents show both doses of upadacitinib (15 mg and 30 mg) monotherapy met all primary and secondary endpoints versus placebo[1]

– No new safety risks were observed compared to the safety profile observed in patients with rheumatoid arthritis and psoriatic arthritis receiving RINVOQ[1-5]

– RINVOQ, a selective and reversible JAK inhibitor discovered and developed by AbbVie, is being studied as a once-daily oral therapy for moderate to severe atopic dermatitis and in several other immune-mediated diseases[1,6-12]

NORTH CHICAGO, IL, USA I June 18, 2020 I AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced upadacitinib (15 mg and 30 mg, once daily) monotherapy met the co-primary endpoints of at least a 75 percent improvement in the Eczema Area Severity Index (EASI 75) and a validated Investigator’s Global Assessment for Atopic Dermatitis (vIGA-AD) of clear or almost clear (0/1) at week 16 in adults and adolescents with moderate to severe atopic dermatitis who are candidates for systemic therapy.¹ Measure Up 1 is the first pivotal Phase 3 study to evaluate the efficacy and safety of RINVOQ for the treatment of moderate to severe atopic dermatitis.

In this study, patients receiving either 15 mg or 30 mg of upadacitinib monotherapy showed significant improvement in skin clearance.¹ Of patients receiving upadacitinib 15/30 mg, 70/80 percent achieved EASI 75 at week 16, respectively, versus 16 percent in the placebo group (p<0.001).¹ Of those treated with upadacitinib 15/30 mg, 48/62 percent of patients achieved vIGA-AD 0/1, respectively, versus 8 percent of patients receiving placebo (p<0.001).¹

“People with atopic dermatitis often struggle with relentless skin and itch symptoms, resulting in a significant unmet need,” said Michael Severino, M.D., vice chairman and president, AbbVie. “We’re excited by these results, which show the potential of RINVOQ for individuals living with the burden of atopic dermatitis.”

For both doses, patients experienced an early reduction in itch, which was maintained through week 16.¹ Clinically meaningful reduction in itch was defined as improvement in Worst Pruritus Numerical Rating Scale (NRS)≥4,¹ which was achieved by a significantly higher proportion of patients receiving upadacitinib 15/30 mg at week 16 compared to placebo (52/60 percent, respectively, versus 12 percent, p<0.001).¹ Clinically meaningful reductions in itch compared to placebo were observed as early as one day after the first dose (day 2) for patients receiving upadacitinib 30 mg (12 percent versus 4 percent, p<0.001) and two days after the first dose (day 3) for patients receiving upadacitinib 15 mg (16 percent versus 3 percent, p<0.001).¹

Measure Up 1 Results at Week 16*,1
	Upadacitinib 15 mg (n=281)	Upadacitinib 30 mg (n=281)	Placebo (n=285)
EASI 75a	70%	80%	16%
vIGA-AD 0/1b	48%	62%	8%
Improvement in Worst Pruritus NRS≥4c	52%	60%	12%
* Co-primary endpoints were EASI 75 and vIGA 0/1 at week 16. Co-primary endpoints achieved p-values of <0.001. Improvement in Worst Pruritus NRS≥4 at day 2, day 3 and week 16 were secondary endpoints. All secondary endpoints achieved p-values of <0.001. Not all secondary endpoints are shown.
a EASI 75 is defined as at least a 75 percent reduction in Eczema Area and Severity Index.
b vIGA-AD 0/1 is defined as a validated Investigator Global Assessment for Atopic Dermatitis of clear or almost clear (0/1) with at least two grades of reduction from baseline.
c Improvement in Worst Pruritus NRS≥4 is defined as an improvement (reduction) in Worst Pruritus NRS≥4. The endpoint was analyzed for participants with pruritus NRS≥4 at baseline.

Atopic dermatitis is a common, chronic, relapsing, inflammatory skin disease that can manifest as a recurring cycle of itching and scratching leading to painful, cracked skin.^13,14 It affects up to an estimated 25 percent of adolescents and 10 percent of adults at some point in their lifetime.¹⁵ Between 20 and 46 percent of adults with atopic dermatitis have moderate to severe disease.¹⁶ The range of symptoms pose significant physical, psychological and economic burden on individuals impacted by the disease.^13,14

“Both adolescents and adults patients living with moderate to severe atopic dermatitis often suffer from an enormous burden of disease that can affect every aspect of their daily life,” said lead investigator Emma Guttman-Yassky, M.D., Ph.D., professor of dermatology and immunology, Icahn School of Medicine at Mount Sinai Medical Center. “It is encouraging to see the high proportion of patients achieving clear or almost clear skin with upadacitinib, and the meaningful and rapid reduction in itch with both doses.”

No new safety risks were observed compared to the safety profile observed in patients with rheumatoid arthritis and psoriatic arthritis receiving RINVOQ.^1-5 In Measure Up 1, serious adverse events occurred in 2.1 percent of patients receiving upadacitinib 15 mg, 2.8 percent of patients receiving upadacitinib 30 mg, and 2.8 percent of patients receiving placebo at week 16.¹ The most common treatment-emergent adverse events were acne, upper respiratory tract infection and nasopharyngitis.¹ Acne was observed with both doses of upadacitinib (6.8 percent of patients on 15 mg and 17.2 percent of patients on 30 mg) versus placebo (2.1 percent of patients) and was mild to moderate in most cases.¹ Eczema herpeticum was observed in patients receiving upadacitinib 30 mg (1.1 percent of patients) and placebo (1.4 percent of patients); it was not observed in patients receiving upadacitinib 15 mg.¹ Serious infections were reported infrequently (0.7 percent of patients receiving upadacitinib 15 mg or 30 mg; none were observed on placebo).¹ No deaths, venous thromboembolic events (VTE) or major adverse cardiac events (MACE) were reported.¹

Full results from Measure Up 1 will be presented at a future medical meeting and published in a peer-reviewed publication. Use of RINVOQ in atopic dermatitis is not approved and its safety and efficacy have not been evaluated by regulatory authorities.

About the Measure Up 1 Study^1,17

Measure Up 1 is a Phase 3, multicenter, randomized, double-blind, parallel-group, placebo-controlled study designed to evaluate the safety and efficacy of upadacitinib in adult and adolescent (12 years or older) patients with moderate to severe atopic dermatitis who are candidates for systemic treatment. Patients were randomized to upadacitinib 15 mg, upadacitinib 30 mg or placebo, followed by either upadacitinib 15 mg or upadacitinib 30 mg at week 16.

The co-primary endpoints were the percentage of patients achieving EASI 75 and a vIGA score of 0/1 after 16 weeks of treatment. Secondary endpoints included Improvement in Worst Pruritus NRS≥4 at week 16, EASI 90, percent change in Worst Pruritus NRS, percent change in EASI at week 16, as well as improvement in Worst Pruritus NRS≥4 at day 2 (one day after the first dose) for patients receiving upadacitinib 30 mg and improvement in Worst Pruritus NRS≥4 at day 3 (two days after the first dose) for patients receiving upadacitinib 15 mg. The trial is ongoing, and the long-term extension period remains blinded to investigators and patients, to evaluate the long-term safety, tolerability and efficacy of the two once-daily doses (15 mg and 30 mg) of upadacitinib in patients who have completed the placebo-controlled period. More information on this trial can be found at www.clinicaltrials.gov (NCT03569293).

About RINVOQ (upadacitinib)

Discovered and developed by AbbVie scientists, RINVOQ is an oral, once-daily, selective and reversible JAK inhibitor studied in several immune-mediated inflammatory diseases.^1,6-12 It was engineered to have greater inhibitory potency for JAK1 versus JAK2, JAK3 and TYK2.² In August 2019, RINVOQ received U.S. Food and Drug Administration approval for adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to methotrexate. In December 2019, RINVOQ also received approval by the European Commission for the treatment of adult patients with moderate to severe active rheumatoid arthritis who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs. The approved dose for RINVOQ in rheumatoid arthritis is 15 mg. Phase 3 trials of RINVOQ in atopic dermatitis, rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis, Crohn’s disease, ulcerative colitis and giant cell arteritis are ongoing.^7-12,14 Use of RINVOQ in atopic dermatitis is not approved and its safety and efficacy have not been evaluated by regulatory authorities.
