A Clinical Trial of TQH3906 Capsules in Adult Patients With Moderate to Severe Plaque Psoriasis

7 septembre 2026 mis à jour par: Chia Tai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., Ltd.

A Randomized, Double-Blind, Parallel-Group, Placebo- and Active-Controlled, Multicenter Phase 3 Clinical Trial to Evaluate the Efficacy and Safety of TQH3906 Capsules in the Treatment of Adult Patients With Moderate to Severe Plaque Psoriasis

This study is a multicenter, randomized, double-blind, placebo- and active-controlled Phase III clinical trial sponsored by Nanjing Shunxin Pharmaceutical Co., Ltd., a subsidiary of Chiatai Tianqing Pharmaceutical Group. The study aims to evaluate the efficacy and safety of once-daily oral TQH3906 capsules (24 mg) in adult participants with moderate to severe plaque psoriasis. TQH3906 is a highly selective TYK2 allosteric inhibitor targeting the JH2 domain, which blocks the IL-23 and Type I interferon inflammatory pathways. Approximately 400 eligible participants aged 18-75 years will be enrolled. Participants will be stratified based on prior biologic use and randomized in a 2:2:1 ratio to the TQH3906 group, the deucravacitinib active control group, or the placebo group. The trial includes a screening period, a 16-week double-blind controlled treatment phase, a 36-week open-label extension phase (during which all participants will receive TQH3906), and a 4-week safety follow-up after the last dose. The co-primary endpoints are the proportion of participants achieving sPGA 0/1 and PASI 90 response at Week 16. Secondary endpoints include improvements in scalp, nail, and palmoplantar psoriasis, Dermatology Life Quality Index (DLQI), long-term safety, and steady-state pharmacokinetic parameters. This study will collect comprehensive efficacy and safety data over 52 weeks to support the New Drug Application (NDA) for TQH3906 for the treatment of plaque psoriasis.

Effects on participants' Psoriasis Area and Severity Index (PASI)
Délai: Baseline up to 52 weeks
Questionnaire: Psoriasis Area and Severity Index (PASI) total score, range 0-72. The body is divided into 4 regions (head, upper extremities, trunk, lower extremities) weighted by 0.1, 0.2, 0.3, 0.4 respectively. Each region is scored for erythema, induration, desquamation (0-4 each) and lesion area (0-6). Higher scores indicate more severe psoriasis.
Baseline up to 52 weeks
Effects on participants' static Physician's Global Assessment (sPGA)
Délai: Baseline up to 52 weeks

Questionnaire: Static Physician's Global Assessment (sPGA) is a single-item static global severity scale (0-4 points) assessing overall psoriasis lesion severity at a single timepoint, based on equal-weighted evaluation of 3 lesion features: erythema, induration, desquamation (each scored 0-4, averaged to final global score).

Scoring grading:

0 = Cleared (no active lesions, residual pigmentation allowed)

  1. = Almost cleared
  2. = Mild
  3. = Moderate
  4. = Severe sPGA 0/1 responder = score 0 or 1 at target visit;
Baseline up to 52 weeks
Effects on participants' Scalp static Physician's Global Assessment (ssPGA)
Délai: Baseline up to 52 weeks

Questionnaire: ssPGA is a static 5-point single-item scale (0 to 4) exclusively evaluating scalp psoriatic lesions, comprehensively and equally assessing three lesion features: erythema, plaque induration/thickening, and scaling limited to scalp only.

Scoring grading:

0 = Clear

  1. = Almost clear
  2. = Mild
  3. = Moderate
  4. = Severe
Baseline up to 52 weeks
Effects on participants' Palmoplantar Psoriasis Physician Global Assessment (pp-PGA)
Délai: Baseline up to 52 weeks

Questionnaire: Palmoplantar Psoriasis Physician Global Assessment (pp-PGA). is a static single-item 5-point scale (score range 0-4), exclusively evaluating plaque psoriasis lesions limited to palms and soles. Investigators equally assess three core lesion features: erythema, hyperkeratosis/induration, scaling (fissures/pain secondary to plaques are referenced as auxiliary manifestations).

Grading definition:

0 = Clear

  1. = Almost clear
  2. = Mild
  3. = Moderate
  4. = Severe
Baseline up to 52 weeks
Effects on participants' Physician's Global Assessment of Fingernail Psoriasis (PGA-F)
Délai: Baseline up to 52 weeks

Questionnaire: Physician's Global Assessment of Fingernail Psoriasis (PGA-F) is a static single-item 5-point scale (score range 0-4), exclusively evaluating psoriatic lesions of all fingernails. Investigators comprehensively assess core nail psoriasis manifestations: nail pitting, onycholysis, subungual hyperkeratosis, splinter hemorrhages, nail discoloration, crumbling.

Grading definition:

0 = Clear

  1. = Almost clear
  2. = Mild
  3. = Moderate
  4. = Severe
Baseline up to 52 weeks
Effects on participants' Dermatology Life Quality Index (DLQI)
Délai: Baseline up to 52 weeks
Questionnaire: The Dermatology Life Quality Index (DLQI) is a validated self-administered 10-item patient-reported questionnaire evaluating the impact of skin disease on quality of life over the prior 7 days. The scale covers 6 domains: symptoms & feelings, daily activities, leisure, work/school, personal relationships, treatment burden. Each question is scored 0 (not at all/not relevant) to 3 (very much); total score ranges from 0 to 30. Lower scores indicate less impairment to quality of life.
