Study Purpose

The purpose of this research study is to compare the efficacy and safety of SCT630 and adalimumab (HUMIRA®) in adults with plaque psoriasis.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 70 Years
Gender All

Subjects had hypersensitivity to test drugs and their excipients, or drugs with the same pharmacological and biological classification as test drugs, and had a history of allergy to active substances or excipients of adalimumab or SCT630. 16. Positive test for anti-nuclear antibody(ANA) or anti-double-stranded DNA antibody at screening. 17. Subjects were accompanied by active neuropathy, including but not limited to multiple sclerosis, Guillain-Barre syndrome, optic neuritis, transverse myelitis, or neurological symptoms suggesting demyelinating lesions of the central nervous system. 18. Positive test for HIV antibodies, hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies ,or Treponema pallidum antibody at screening. 19. The results of five tests for hepatitis B virus infection should be further tested for hepatitis B virus DNA, if it is greater than or equal to the upper limit of the reference value of each hospital. 20. Women who are pregnant or nursing.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions


Experimental: SCT630

Participants received 80 mg SCT630 subcutaneously on week 1/day 1 (initial loading dose) and 40 mg at week 2 and every 2 weeks thereafter until week 16. Participants with a PASI 50 response at week 16 continued to receive 40 mg SCT630 until week 48.

Active Comparator: adalimumab-EU source

Participants received 80 mg adalimumab subcutaneously on week 1/day 1 (initial loading dose) and 40 mg at week 2 and every 2 weeks thereafter until week 16. At week 16 participants with a PASI 50 response were re-randomized to treatment with adalimumab or were transitioned to SCT630 until week 48
