Brief 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.

Conditions

Plaque Psoriasis

Outcome Measures

Primary Outcomes (1)

• 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.

Apremilast for Treatment of Psoriasis with the AM-endotype

EXPERIMENTAL

Psoriasis patients with the AM-endotype will be followed during treatment over 16 weeks with 5 monthly individual blood draws will be enrolled.

Drug: Apremilast

Interventions

Apremilast DRUG

Apremilast will be given as approved by the FDA for the treatment of moderate to severe plaque psoriasis. An initial dosage titration from Day 1 (10mg) to Day 5 (30mg). Following the titration, the recommended maintenance dosage of 30 mg twice daily taken orally starting on Day 6 will be dispensed, as per labeled indication.
