NCT04630652

Brief Summary

Although the newly developed biologics (drugs derived from living cells cultured in a laboratory) are highly effective in controlling psoriasis, all the biologics should be continuously injected to suppress recurrence of the disease. In this regard, the observation in the phase II clinical trial conducted by us (Laboratory for Investigative Dermatology at the Rockefeller University) was groundbreaking that just a single dose of anti-IL-23p19 antibody (risankizumab, trade name: Skyrizi, study drug in this clinical trial) administration produced disease clearance up to 66 weeks in 46% (6 of 13) of patients. However, there is a lack of understanding about immune regulation in human skin induced by anti-IL-23p19 antibody injection, and there is a need to conduct a psoriasis clinical trial for single-cell sequencing immune cells in human psoriasis skin before and after anti-IL-23p19 antibody administration, and to correlate regulatory immune cell alterations with clinical disease progression. The overall objective of the clinical trial is to study regulatory immune cell alterations induced by anti-IL-23p19 antibody administration in psoriasis patients who achieve long-term disease clearance off drugs.

  • Females who are pregnant, lactating, planning on pregnancy during the study period, or unwilling to use a medically acceptable method of birth control.
  • Severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, cardiac, or neurological disease, or any other medical condition that, in the investigator's opinion, places the participant at risk by participating in this study.
  • Any medical history, including laboratory results, deemed by the investigator to be likely to interfere with their participation in the study, or to interfere with the interpretation of the results, or any social condition that, in the opinion of the Investigator, might pose additional risk to the participant or confound the results of the study.

Model Details: The interventional study model is to treat moderate-to-severe psoriasis patients with risankizumab for 4 months and analyze pre- and post-treatment skin biopsy samples to (i) identify regulatory immune cell alterations induced by risankizumab administration in the skin of patients whose psoriasis is cleared without recurrence and (ii) develop pre-treatment predictive models for psoriasis patients that anticipate disease clearance and recurrence.
