Brief Summary

This study has been designed to explore the clinical efficacy and safety of HS-10374 in the treatment of moderate to severe plaque psoriasis. Additionally, this study is to find the optimal dosing for the future clinical development of HS-10374.

Detailed Description

This is a 12-week, multi-center, randomized, double blind, placebo-controlled, Phase 2 study. The study duration includes a 4-week screening period, a 12-week treatment period, and a 4-week follow-up period. All eligible subjects will be randomly assigned to 1 of 3 treatment arms (HS-10374 Dose 1, HS-10374 Dose 2, and placebo) in an equal ratio.

Primary Outcome Measures
NameTimeMethod
Proportion of patients with moderate to severe plaque psoriasis achieving PASI 75 response at Week 12Baseline to Week 12

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity. PASI 75 response is defined as 75% or greater improvement in PASI score from baseline.

Secondary Outcome Measures
NameTimeMethod
Incidence, severity and association with the study drug of adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuationBaseline to Week 16
PASI 50 response rates at specified time pointsBaseline to Week 16

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity. PASI 50 response is defined as 50% or greater improvement in PASI score from baseline.

Change from baseline in PASI scores at specified time pointsBaseline to Week 16

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity.

Number of participants with abnormalities of physical examinationBaseline to Week 16

Physical examination includes assessments of general appearance, skin, lymph nodes, head, neck, lung, heart, abdomen, spine, extremities, nervous system, etc.

Incidence of clinically significant changes in electrocardiogram (ECG)Baseline to Week 16

ECG parameters include heart rate, PR interval, RR interval, QRS duration, QTcF interval.

PASI 90 response rates at specified time pointsBaseline to Week 16

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity. PASI 90 response is defined as 90% or greater improvement in PASI score from baseline.

CtroughBaseline to Week 12

Trough observed plasma concentration.

Number of participants with clinical laboratory abnormalitiesBaseline to Week 16

Clinical laboratory tests include hematology, coagulation testing, blood chemistry, urinalysis, stool analysis, high-sensitivity C-reactive protein, etc.

Number of participants with abnormalities of vital signsBaseline to Week 16

Vital signs measured include blood pressure, pulse rate, and temperature.

Proportion of patients with sPGA 0/1 at specified time pointsBaseline to Week 16

Static physician's global assessment (sPGA) of psoriasis is an average assessment of all psoriatic lesions based on erythema, induration, and scale. It's a 5-point scale performed by investigators. A sPGA score of 0 or 1 means "clear" or "almost clear" respectively.

PASI 100 response rates at specified time pointsBaseline to Week 16

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity. PASI 100 response is defined as 100% improvement in PASI score from baseline.

Change from baseline in DLQI scores at specified time pointsBaseline to Week 16

The dermatology life quality index (DLQI) is a patient reported outcome measurement. It's a questionnaire consisting of 10 questions concerning patients' perception of the impact of skin diseases on different aspects of their health-related quality of life over the last week. Each question is scored on a scale of 0 to 3, and the sum of each scores range from 0 (no impairment of life quality) to 30 (maximum impairment).

Change from baseline in BSA at specified time pointsBaseline to Week 16

Psoriasis body surface area (BSA) involvement is measured using the handprint method with the size of a patient's handprint representing \~1% of body surface area involved.

PASI 75 response rates at specified time pointsBaseline to Week 16

Psoriasis Area and Severity Index (PASI) is a scoring system quantifying the severity of psoriasis based on both lesion severity and area of involvement. PASI assessment is performed by investigators, and the numeric score ranges from 0 to 72, with higher PASI scores denoting more severe disease activity. PASI 75 response is defined as 75% or greater improvement in PASI score from baseline.
