Current Secondary Outcome Measures  ICMJE
 (submitted: August 27, 2019)
  • Preliminary Efficacy by Physician Global Assessment (PGA) [ Time Frame: From enrollment to end of treatment at 8 Weeks ]
    The Physician Global Assessment (PGA) is a 6-point scoring system used to assess disease severity at a given time point. The PGA is a six-point score that summarizes the overall quality (erythema, scaling and thickness) and extent of Psoriasis plaques where (0) is clear, (1) minimal, (2) mild, (3) moderate, (4) severe, and (5) being very severe psoriasis. Change in score from baseline through Week 8 will be assessed.
  • Preliminary Efficacy by Psoriasis Area and Severity Index (PASI) [ Time Frame: From enrollment to end of treatment at 8 Weeks ]
    Psoriasis Area and Severity Index (PASI) is the most widely used tool for the measurement of severity of psoriasis. PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease). Change in score from baseline through Week 8 will be assessed.
  • Secondary Safety Measures: Other Non-DLT Adverse Events [ Time Frame: From enrollment to end of treatment at 8 Weeks ]
    Frequency and type of Non-DLT adverse events (graded according to National Cancer Institute's Common Toxicity Criteria for Adverse Events [NCI-CTCAE v 5.0]),

Change in score from baseline through Week 8 will be assessed.
  • Dermatology Life Quality Index (DLQI) [ Time Frame: From enrollment to end of treatment at 8 Weeks ]
    The Dermatology life Quality Index (DLQI) is a ten-question questionnaire used to measure the impact of skin disease on the quality of life of an affected person. The 10 questions cover the following topics: symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, treatment. Each question refers to the impact of the skin disease on the patient's life over the previous week. Each question is scored from 0 to 3, giving a possible score range form 0 (meaning no impact of skin disease on quality of life) to 30 (meaning maximum impact on quality of life). Change in score from baseline through Week 8 will be assessed.

Descriptive Information
Brief Title  ICMJE Autologous Natural Killer Cells in Subjects With Plaque Psoriasis
Official Title  ICMJE Phase 1, Open-Label, Safety Study of Escalating Doses of Ex Vivo Expanded, Autologous Natural Killer Cells in Subjects With Plaque Psoriasis
Brief 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.
Detailed 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.
