Study Overview
Brief Summary
This is a Phase I/II Study of MH004 in Healthy Adult Volunteers, participants with Mild to Moderate Atopic Dermatitis.
Detailed Description
The study includes 2 parts: The first part (Phase I) is the first-in-human trial of MH004, consisting of a single ascending dose (SAD) study and a multiple ascending dose (MAD) study in healthy volunteers. The second part is a multi-center, randomized, double-Blind, vehicle-controlled phase II study to evaluate the safety, tolerability and PK of MH004 Ointment for AD participants, using defined concentrations of the topical cream based on the PK and safety data in healthy volunteers in Phase I.

- •Any other concomitant skin disorder, pigmentation, or extensive scarring that, in the opinion of the investigator, may interfere with the evaluation of AD lesions or compromise participant safety.
- •Presence of AD lesions only on the hands or feet without prior history of involvement of other classical areas of involvement such as the face or the folds.
- •Other types of eczema.
- •Clinically significant cardiac disease; new cerebral infarction within 6 months from dosing; malignancies within 5 years from dosing; low hemoglobin; severe renal disease on dialysis; liver disease.

Outcomes
Primary Outcomes
Phase I: Incidence and severity of Treatment-Emergent Adverse Events (Safety and Tolerability)
Time Frame: 1 year
Assess incidence and severity of treatment-emergent adverse events as determined by CTCAE v5.0 The incidence, nature, and severity of AEs/SAEs including relationship to study treatment from MAD initial study drug administration time of randomization until Day 14 for MAD participants. The incidence, nature, and severity of AEs/SAEs leading to treatment discontinuation from MAD initial study drug administration time of randomisation until Day 7 for MAD participants. Clinically significant changes in laboratory parameters, vital signs, 12-lead ECG, and other safety assessments from initial study drug administration time of randomisation until Day 7 for SAD participants. Clinically significant changes in laboratory parameters, vital signs, 12-lead ECG, and other safety assessments from MAD initial study drug administration time of randomisation until Day 14 for MAD participants.
Phase II: Mean Percentage Change From Baseline in EASI Score at Week 4 in Participants Treated With MH004 Ointment
Time Frame: Baseline and week 4.
EASI is a validated composite scoring system integrating the proportion of the body region (area) involved and the intensity of key signs of atopic dermatitis (AD). The EASI score examines 4 areas of the body and weights them for participants 8 years of age and older as follows: Head/Neck (H) = 0.1, Upper limbs (UL) = 0.2, Trunk (T) = 0.3, and Lower limbs (LL) = 0.4. The severity strata for the EASI are as follows: 0 = clear; 0.1 to 1.0 = almost clear; 1.1 to 7.0 = mild; 7.1 to 21.0 = moderate; 21.1 to 50.0 = severe; 50.1 to 72.0 = very severe. The total EASI score for each region is calculated by multiplying the severity score by the area score, with adjustment for the proportion of the body region to the whole body. The total EASI score ranges from 0 to 72. A higher score indicated worse disease status, and a negative change from baseline indicated improvement.
