Registration Number
NCT06552520
Lead Sponsor
Shanghai Chia Tai Tianqing Pharmaceutical Technology Development Co., Ltd.
Brief Summary

This is a randomized, double-blind, placebo-controlled clinical trial with 500 participants. In this study, the safety evaluation used the common toxic reaction criteria of the National Cancer Institute to evaluate the adverse events of the drugs, and the effectiveness evaluation used the eczema area and severity score and the overall investigator score to confirm the efficacy.

Primary Outcome Measures
NameTimeMethod
Participants who achieved EASI-75 (≥75% improvement from baseline) on the eczema Area and Severity score (EASI)Baseline to 16 weeks after treatment

Percentage of participants who achieved EASI-75 (≥75% improvement from baseline) on the eczema Area and Severity score (EASI)

Subjects with an Investigator's Overall Rating (IGA) score (5-scale) of 0 or 1 and ≥2 points decline from baselineBaseline to 16 weeks after treatment

Percentage of subjects with an Investigator's Overall Rating (IGA) score (5-scale) of 0 or 1 and ≥2 points decline from baseline.

Secondary Outcome Measures
NameTimeMethod
Eczema area and severity score (EASI) change from baselineFrom baseline to week 60

The affected area of each site was assessed. According to the percentage of the affected area, the corresponding Region score was 0 to 6. The higher the score, the more severe the involvement.

Rate of change from baseline in the Investigator's overall Score (IGA)After medication to 60 weeks

The researchers assessed the form of the dermatitis using a 5-point scale (0-5), with higher scores being more severe.

Change rate of atopic dermatitis score (SCORAD) from baselineAfter medication to 60 weeks

According to the involvement of skin surface area, the severity of skin lesions and the subjective symptom score, the higher the value, the more severe the dermatitis.

Incidence of neutralizing antibodies (Nab)After medication to 60 weeks

Incidence of neutralizing antibodies (Nab)

Rate of change in dermatological quality of life (DLQI) score from baselineAfter medication to 60 weeks

Assess how much the skin problems of the last week have affected the subjects' lives

Change in patients' self-assessment of eczema (POEM) from baselineAfter medication to 60 weeks

The number of days in the past 7 days to assess whether eczema caused skin problems such as itching and bleeding, 0 indicates no days, 1 indicates 1-2 days, 2 indicates 3-4 days, 3 indicates 5-6 days, and 4 indicates all days.

The incidence of adverse eventsAfter medication to 60 weeks

Adverse events that occur during treatment

The incidence and titer of drug-resistant antibodies (ADA) in subjectsAfter medication to 60 weeks

The incidence and titer of drug-resistant antibodies (ADA) in subjects

Change of body surface area from baseline in moderate to severe atopic dermatitisAfter medication to 60 weeks

The researchers used a nine-point scale to assess the percentage of AD affected area in the whole body (0-100%), with the larger the value, the more severe the involvement.

Steady valley concentration of TQH2722After medication to 60 weeks

Relatively stable concentration levels of TQH2722

Change in daily Peak Itch Digital Rating Scale (NRS) score from baselineAfter medication to 60 weeks

Rate the most severe itching in the past 24 hours on a scale of 0-10, with higher numbers being more severe.
