Clinical Trial Summary

This is an open label pilot study of the impact of treatment with standard dosing of Otezla for 16 weeks on AM-endotype psoriasis patients, identified by elevated (>150% of normal): 1.) Intermediate (CD14++CD16+) monocytes, or 2.) circulating monocyte doublets, or 3.) circulating monocyte-platelet aggregates (MPA).

Approximately 25 psoriasis patients with the AM-endotype will be followed during treatment over 16 weeks with 4 monthly individual blood draws will be enrolled. All treated psoriasis subjects will receive apremilast through Week 16.

Other	Evaluate Median Changes in Flow Cytometric Quantification of Monocytes	To assess change in quantitation of additional monocyte and neutrophil markers, including CD18/CD11b and NETotic neutrophils by computing relative percent reduction in circulating CD18/CD11b and NETotic neutrophils for each subject being treated.	16 weeks
Other	Monocyte Transcriptome Biomarkers	To assess change in expression levels of monocyte transcriptome biomarkers using quantitative PCR to measure changes from baseline to 16 weeks in identified monocyte genes.	16 weeks
Other	Percent Change in Dermatology Life Quality Index (DLQI)	Calculate the percent change in Dermatology Life Quality Index (DLQI) from baseline to 16 weeks in patients.	16 weeks
Other	Percent Change Between Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI: PSO	Calculate the percent change Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI: PSO) from baseline to 16 weeks in patients treated with apremilast 30 mg BID	16 weeks
Primary	The Primary Outcome Measure Will be to Evaluate Change in Aberrant Inflammatory Profiles of Activated Blood Monocytes (Aberrant-monocyte Endotype Patients (AM-endotype).	For each subject, we will identify a target biomarker of abnormally elevated monocytes, among 1.) intermediate, or 2.) doublets, or 3.) platelet doubles. Each subject will thus have one identified monocyte biomarker for which relative percent change will be its basis for analysis in the primary outcome measure. We will specifically assess change from baseline to 16 weeks by computing relative percent reduction for each subject being treated. Note for example that a change of 1.5% to 1.2% is (1 - (1.2/1.5))*100% = 20% reduction. The median and other summary statistics of these percent change values will be computed. Wilcoxon's signed rank test will be used to evaluate the null hypothesis of the median percent change being 0.	Baseline, Week 16
Secondary	Change in Serum Myeloperoxidase	To assess change in serum myeloperoxidase in the identified patient AM-endotype computing relative percent reduction for each subject being treated and serum marker. The median and other summary statistics of these percent change values will be computed	Baseline, Week 16
Secondary	Change in TNF Alpha	To assess change in in the identified patient AM-endotype computing relative percent reduction for each subject being treated and serum marker. The median and other summary statistics of these percent change values will be computed	Baseline, Week 16
Secondary	Change in IL-17	To assess change in IL-17 in the identified patient AM-endotype computing relative percent reduction for each subject being treated and serum marker. The median and other summary statistics of these percent change values will be computed	Baseline, Week 16
