Pooled Results from Incyte’s TRuE-AD1 and TRuE-AD2 Atopic Dermatitis Studies of Ruxolitinib Cream Show Clinically Meaningful Improvements in Patient-Reported Quality of Life Assessments

Incyte (Nasdaq:INCY) today announced efficacy and safety results from a pooled analysis of two randomized, double-blind, vehicle-controlled Phase 3 studies – TRuE-AD1 and TRuE-AD2 – evaluating ruxolitinib cream for the treatment of patients with mild-to-moderate atopic dermatitis (AD). The presentation (FC08.08) will be available on-demand as part of the 29th European Academy of Dermatology and Venereology (EADV) Congress, held virtually from October 29-31, 2020.

Key findings from the individual TRuE-AD1 and TRuE-AD2 studies were previously reported.

The new, pooled data reinforce that treatment with ruxolitinib cream resulted in a rapid, substantial and sustained reduction in itch; and improved the extent and severity of AD as measured by the Eczema Area Severity Index (EASI) and Scoring Atopic Dermatitis (SCORAD) assessment tools.

In addition, treatment with ruxolitinib cream resulted in notable improvements in quality of life measures such as the PROMIS (Patient-Reported Outcomes Measurement Information System)¹ sleep disturbance (8b)² score. PROMIS is a set of well-accepted patient-reported outcome measurement tools that are psychometrically supported.¹ In the TRuE-AD trials, the PROMIS Short Form-Sleep Disturbance (8b) questionnaire was used to assess patients’ self-reported perceptions of sleep quality, sleep depth and restoration associated with sleep.

Key results from the pooled analysis include:
	Ruxolitinib cream 0.75% BID	Ruxolitinib cream 1.5% BID	Vehicle
Primary endpoint
IGA-TS, responders	n=483	n=481	n=244
	44.7%*	52.6%*	11.5%
Key secondary endpoints
EASI-75, responders	n=483	n=481	n=244
	53.8%*	62.0%*	19.7%
Itch NRS (≥4-point improvement)†, responders	n=313	n=307	n=158
	41.5%*	51.5%*	15.8%
PROMIS Short Form-Sleep Disturbance (8b) (≥6-point improvement)‡, responders	n=446	n=449	n=226
	20.9%**	23.8%**	14.2%
Secondary endpoint
SCORAD, mean change from baseline	n=483	n=481	n=244
	-62.9%*	-67.3%*	-30.4%
Additional efficacy analysis
Daily Itch NRS Score, mean change from baseline within 12 hours	n=483	n=481	n=244
	-0.4***	-0.5***	-0.1
IGA-TS: Investigator’s Global Assessment (IGA)-Treatment Success defined as an IGA score of 0 (clear) or 1 (almost clear) with ≥2-point improvement from baseline at Week8; BID: twice daily; EASI-75: ≥75% improvement from baseline at Week 8 in the Eczema Area and Severity Index (EASI) score; NRS: Numerical Rating Scale; PROMIS: Patient-Reported Outcomes Measurement Information System; SCORAD: Scoring Atopic Dermatitis. †Patients included in the analysis had an Itch NRS score ≥4 at baseline; ‡Patients included in the analysis had a PROMIS Short Form-Sleep Disturbance (8b) score of ≥6 at baseline. *P<0.0001 vs. vehicle at Week 8; **P<0.05 vs. vehicle at Week 8; ***P<0.02 vs. vehicle.

The overall safety profile of ruxolitinib cream was consistent with previously reported data, with no new safety signals observed in this pooled analysis.

“Atopic dermatitis is a chronic inflammatory skin condition that may result in decreased quality of life for patients; attributable in part to sleep disturbances resulting from intense and persistent itch,” said Jim Lee, M.D., Ph.D., Group Vice President, Inflammation & AutoImmunity, Incyte. “Pooled results from the TRuE-AD studies reinforce the potential of ruxolitinib cream to become an important antipruritic and anti-inflammatory treatment option for patients with atopic dermatitis and we are on track to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration at the end of this year.”

About Atopic Dermatitis

Atopic dermatitis (AD) is a common chronic and intensely pruritic disease characterized by inflammation of the skin. AD affects more than 30 million individuals in the United States and 80-90% of patients have mild-to-moderate disease. Signs and symptoms of AD include irritated and itchy skin that can cause red lesions that may ooze and crust. Patients with AD are also more susceptible to bacterial, viral and fungal infections.

About TRuE-AD

The TRuE-AD clinical trial program consists of two randomized, double-blind, vehicle-controlled Phase 3 studies, TRuE-AD1 (NCT03745638) and TRuE-AD2 (NCT03745651), evaluating the safety and efficacy of ruxolitinib cream compared to vehicle (non-medicated cream) in patients with atopic dermatitis (AD). Both studies enrolled more than 600 patients (age ≥12 years) diagnosed with AD for at least two years and who were candidates for topical therapy.

Patients with an Investigator’s Global Assessment (IGA) score of 2 to 3, and with AD on 3% to 20% of their Body Surface Area (excluding scalp) were randomized 2:2:1 into one of three arms for eight weeks: ruxolitinib cream 0.75% applied twice daily (BID); ruxolitinib cream 1.5% applied BID; and vehicle. Participants who successfully completed an assessment at Week 8 were offered participation in the 44-week long-term safety treatment extension period with ruxolitinib cream 0.75% or 1.5% applied BID.

The primary endpoint of the TRuE-AD studies was the proportion of participants achieving an Investigator’s Global Assessment Treatment Success (IGA-TS), defined as an IGA score of 0 (clear) or 1 (almost clear) with at least a 2-point improvement from baseline at Week 8. Key secondary endpoints include: the proportion of patients achieving at least a 75% improvement from baseline in the Eczema Area and Severity Index (EASI-75) score, the proportion of participants with at least a 4-point improvement in the itch Numerical Rating Scale, and the proportion of participants with at least a 6-point improvement in the Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form – Sleep Disturbance (8b) 24-hour recall score. Additional secondary endpoints include mean percentage change from baseline in Scoring Atopic Dermatitis (SCORAD) score. The studies have also been tracking the frequency, duration and severity of adverse events associated with the use of ruxolitinib cream.
