Phase 3

Not yet recruiting

• Conditions: Atopic Dermatitis
• Interventions: Drug: QLM3003 Placebo; Drug: 1.5% QLM3003 ointment; Drug: 2% QLM3003 ointment

• Registration Number: NCT06880276
• Lead Sponsor: Qilu Pharmaceutical Co., Ltd.

Brief Summary

It is a multicenter, randomized, double-blind, placebo-controlled, parallel-group phase 3 clinical trial to evaluate the efficacy of QLM3003 ointment at week 8 based on the primary endpoint (EASI 75) and key secondary endpoint (IGA-TS).in patients with mild to moderate atopic dermatitis. A total of 360 patients with mild to moderate atopic dermatitis are planned to be included and randomized at a ratio of 1:1:1 to receive 1.5% QLM3003 ointment、2% QLM3003 ointment and placebo, twice a day.

Recruitment & Eligibility

• Status: NOT_YET_RECRUITING
• Sex: All
• Target Recruitment: 360

Inclusion Criteria

• Male or female, 18-75 years old
• The diagnosis of atopic dermatitis (AD) during screening meets the Hanifin⁃Rajka standard, and the history of AD/ eczema ≥1 year before screening. All of the following conditions must be met during the screening and baseline periods:Number of participants with IGA score of "2" or "3".AD involving the head and neck (scalp excluded), trunk, and extremities, with a total affected BSA of 3-20% (inclusive)

Exclusion Criteria

• Subjects with comorbidities or other conditions that may interfere with the assessment of the investigational drug or the study disease, as determined by the investigator to be ineligible for participation
• Patients whose current AD disease status was assessed by the investigators to be unstable (spontaneous improvement or rapid deterioration) were not eligible to participate in the study.
• Patients who have received a marketed or investigational biologic for the treatment of AD, such as Dupilumab, within 3 months before baseline or within 5 half-lives of the drug (whichever was longer).
• Patients who had received systemic or topical JAK inhibitor therapy, including but not limited to Tofacitinib, Ruxolitinib, Upadacitinib, Baricitinib, Abrocitinib, Ivarmacitinib, and Gecacitinib, within 4 weeks before baseline or within 5 half-lives of the drug (whichever was longer).

Primary Outcome Measures

Name	Time	Method
Percentage of Participants Achieving >=75% Improvement in Eczema Area and Severity Index Total Score (EASI-75) From Baseline at Weeks 8	Baseline, Week 8	EASI evaluates severity of participant's AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions(head and neck, upper limbs, trunk \[including axillae and groin\] and lower limbs \[including buttocks\]) on4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in each 4 body region: 0 (0%), 1 (\>0 to \<10%), 2 (10 to \<30%), 3 (30 to \<50%), 4 (50 to \<70%), 5 (70 to \<90%) and 6 (90 to 100%). Total EASI score =0.1\*Ah\*(Eh+Ih+Exh+Lh) + 0.2\*Au\*(Eu+Iu+ExU+Lu) + 0.3\*At\*(Et+It+Ext+Lt) + 0.4\*Al\*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants Achieving Investigator's Global Assessment (IGA) Score Clear (0) or Almost Clear (1) and a Reduction From Baseline of Greater Than or Equal to ( >=2) Points at Week 8	Baseline, Week 8	IGA assesses severity of participant's AD on a 5 point scale. 0= clear, no inflammatory signs of AD; 1= almost clear, AD not fully cleared- light pink residual lesions (except post-inflammatory hyperpigmentation), just perceptible erythema, papulation/induration lichenification, excoriation, and no oozing/crusting; 2= mild AD with light red lesions, slight but definite erythema, papulation/induration, lichenification, excoriation and no oozing/crusting; 3= moderate AD with red lesions, moderate erythema, papulation/induration, lichenification, excoriation and slight oozing/crusting and 4= severe AD with deep dark red lesions, severe erythema, papulation/induration, lichenification, excoriation and moderate to severe oozing/crusting. Higher scores indicating more severity of AD. Assessment excluded soles, palms and scalp.
