Clinical Trial Summary

Psoriasis is a non-contagious erythematous scaly skin disease characterized by epidermal proliferation and inflammation. The etiology is related to heredity, infection, allergies, metabolic disorders and autoimmunity. The incidence of psoriasis in the survey was about 1.2‰ in 1984 in China, and 2.6% in the United States. In recent years, the incidence of psoriasis has been on the increase trend, mostly in the young to middle age adults, and it can last a lifetime. The characteristic of the disease is that it usually spreads all over the body, or gradually aggravates, or is fixed and difficult to subside,or the disease course is long, lingering and difficult to heal, and it brings great harm to the patient's body and mind. At present, there is no effective treatment for psoriasis. Although western medicine has good short-term curative effects, prolonged use is not advocated because of adverse side effects and poor long-term effects. Besides, it is easy to relapse and aggravate after stopping the medicine. Psoriasis belongs to the category of "baibi" in Chinese medicine. Doctors of the past dynasties mostly treated it from blood heat, blood stasis, and blood deficiency syndrome. Researcher Zhu Renkang believes that "blood with heat" is the main cause of psoriasis and famous TCM dermatologists such as Zhang Zhili, Gu Bohua, Xu Yihou and others all regard "blood-heat syndrome" as the basic pathogenesis of psoriasis. We used Qingre Liangxue Recipe Granules to observe the treatment of 31 patients with blood-heat type psoriasis vulgaris, and found that the PASI index of the patients after treatment was significantly lower than before treatment (P <0.01), and the serum VEGF level was significantly decreased (P < 0.01), the correlation analysis between the two showed a significant correlation. This study aims to further evaluate the efficacy and safety of Qing-Re-Liang-Xue Decoction in comparison with commonly used glucocorticoids and calcipotriol ointment in patients with blood-heat type psoriasis vulgaris.

Description:

This is a multi-center, randomized, open-label, controlled pilot study of Traditional Chinese medicine (Qing-Re-Liang-Xue Decoction) as a complementary therapy to treat psoriasis vulgaris of blood-heat syndrome during a 10-week period. We estimate to enroll 200 subjects (treatment group(N=100); controlled group(N=100)).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	participants achieving either a major clinical response or partial clinical response defind by Psoriasis Area Severity Index (PASI) over the 10 weeks treatment period.	Psoriasis Area Severity Index (PASI) is usually used to measure the clinical activity diseases of psoriasis.	10 weeks
Secondary	Changes in skin lesions are assessed by dermoscope.	Image data of skin lesions, capillaries in the nail bed, capillaries near the wing of the nose, etc will be analyzed by the Image-Pro Plus software(Version 6.0,Media Cybernetics) to figure out the inner diameter of the blood vessel wall thickness ratio, Wall cavity cross-sectional area ratio and density.	10 weeks.
Secondary	Evaluation of curative effect of Traditional Chinese medicine is assessed by patient reported outcome(PRO) and clinician reported outcomes(CRO).	Healed: TCM syndromes and skin lesions disappeared, only pigmentation spots or depigmentation spots remained, and no new skin rashes. The TCM syndrome score is reduced by more than 90%; markedly effective: TCM syndromes and skin lesions have basically disappeared or only a few intractable small pieces remain, and the skin lesions are still slightly infiltrated. TCM syndrome scores are reduced by 60-89%; effective: TCM syndromes are significantly reduced, and skin lesions have subsided by more than 30%. TCM syndrome scores are reduced by 30-56%; ineffective: after 3 courses of treatment, the skin lesions still have no progress or the skin lesions have subsided by less than 30%. The reduction of TCM syndrome points is less than 30%.	10 weeks.
Secondary	Compliance evaluation is assessed by Counting Days of Treatment.	Compliance=The number of days the subject has received treatment/The number of days the subject should receive treatment*100%	10 weeks.
