Autologous Natural Killer Cells in Subjects With Plaque Psoriasis

Plaque Psoriasis Clinical Trial

Official title: Phase 1, Open-Label, Safety Study of Escalating Doses of Ex Vivo Expanded, Autologous Natural Killer Cells in Subjects With Plaque Psoriasis

Status Completed

Clinical Trial Summary

This is a non-randomized, dose escalating and open-labeled clinical trial to evaluate the safety of autologous natural killer cell (NK) infusions (IV) of "SNK01" in adults with plaque psoriasis. The primary objective of this study is to investigate the safety and tolerability of four infusions of "SNK01" in subjects with plaque psoriasis. Secondary objective is preliminary efficacy of "SNK01" in subjects with plaque psoriasis.

Clinical Trial Description

Nine (9) subjects, male or female, aged 18 years or older will be enrolled in the study, all of whom will receive "SNK01" without placebo control. There are three (3) subjects in each of the three (3) cohorts. The SNK01 study product will be administered at the following doses using dose escalating rules: Cohort 1 will receive 4 weekly infusions of 1 billion cells, Cohort 2 will receive 4 weekly infusions of 2 billion cells, and Cohort 3 will receive 4 weekly infusions of 4 billion cells. Length of participation, per subject, is approximately 12 weeks. The primary endpoint for safety is dose-limiting toxicity (DLT) which is defined as TEAE of grade ≥ 3 considered related to SNK01. Secondary safety endpoints include other adverse events (graded according to National Cancer Institute's Common Toxicity Criteria for Adverse Events [NCI-CTCAE v 5.0]), vital sign measurements, clinical laboratory tests and physical examination. Preliminary efficacy will be measured by Psoriasis Area Severity Index (PASI) and by the Physician's Global Assessment (PGA. ;
