A Study to Evaluate the Equivalence of IBI3027 and Dupilumab Injection in Participants With Moderate to Severe Atopic Dermatitis

NCT07754786 | Not Yet Recruiting Phase 3

• 1 other identifier: CIBI3027A301
• Study Type: interventional
• Target: 520
• Locations: 1 country
• Sites: 1

Brief Summary

This study is expected to include approximately 520 patients with moderate to severe AD, and they will be randomly assigned to the treatment group (IBI3027) and the control group (Dupilumab Injection ) in a 1:1 ratio. Study period: It includes a screening period (4 weeks), a treatment period (44 weeks), and a follow-up period (8 weeks). After screening is completed, participants will be randomly grouped in a 1:1 ratio. On Day 1 (D1), they will receive a loading dose of either IBI3027 or Dupilumab Injection 600 mg by subcutaneous injection (SC), followed by 300 mg each time, SC administration, once every 2 weeks (Q2W), until the last administration on W44. After the treatment is completed, a 8-week safety follow-up will be conducted.

Conditions

Atopic Dermatitis

Outcome Measures

Primary Outcomes (1)

• The proportion of participants who achieved EASI-75

  EASI is an assessment tool used to evaluate the severity of atopic dermatitis and the extent of skin lesions involved. The score of EASI ranges from 0 to 72 points. The higher the score, the more severe the disease. EASI divides the affected areas into four regions: head and neck, trunk, upper limbs, and lower limbs. Scores are given for each region based on the area of involvement. The severity of skin lesions in each region is calculated according to the severity of erythema, sclerosis or papules, epidermal desquamation, and lichenification. Finally, the scores of the four regions are added together to obtain the total score.

  Week 16

Secondary Outcomes (7)

• The proportion of participants who reached EASI-75

  Week 24＆Week 52

• The proportion of participants who reached EASI-50

  Week16、Week24、Week52

• The proportion of participants who achieved EASI-90

  Week16、Week24、Week52

• The change in the EASI score compared to the baseline

  Week16、Week24、Week52

• The overall assessment by the researchers - the proportion of participants who achieved treatment success (IGA-TS, with an IGA score of 0 or 1 and a reduction of ≥ 2 points from the baseline)
