Psoriasis vulgaris is a common inflammatory condition of the skin that results in well-demarcated, scaly, erythematous, itchy plaques. In the United States, psoriasis remains a common, immune-mediated disease, affecting 7.4 million adults. Often topical prescription medications are used as first line treatment for moderate psoriasis. Some topical medications have side effects and risk with long time use, thus not ideal for extensive and indefinite amount of time. Conversely, over- the-counter emollient treatments are readily available, safe and potentially efficacious. This study is design to test the safety and efficacy of topical application of the Metaderm product cream. The Metaderm cream is non-prescription, natural product.

Inclusion Criteria for patients with plaque psoriasis 3-10% BSA

Subjects must satisfy the following criteria to be enrolled in the study:

1. Must be in general good health (except for disease under study) as judged by the Investigator, based on medical history, physical examination, clinical laboratories, and urinalysis. (NOTE: The definition of good health means a subject does not have uncontrolled significant co-morbid conditions).

    Exclusion Criteria

    The presence of any of the following will exclude a subject from enrollment:

13. Other than disease under study, any clinically significant (as determined by the Investigator) cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal, hematologic, immunologic disease, or other major disease that is currently uncontrolled.

14. Any condition, including the presence of laboratory abnormalities, which would place the subject at unacceptable risk if he/she were to participate in the study.

15. Prior history of suicide attempt at any time in the subject's life time prior to screening or randomization, or major psychiatric illness requiring hospitalization within the last 3 years.

16. Pregnant or breast feeding.

17. Active substance abuse or a history of substance abuse within 6 months prior to Screening.

18. Use of any investigational drug within 4 weeks prior to randomization, or 5 pharmacokinetic/pharmacodynamic half lives, if known (whichever is longer).

19. Prior treatment with the investigational product

20. Unable to comply with the protocol (as defined by the Investigator; i.e. drug or alcohol abuse or history of noncompliance)

21. Any other dermatologic conditions that prohibit or confound the ability of the investigator to interpret skin and/or nail exam findings.

22. Patients who will be unable to avoid the use of systemic steroids, excluding intranasal or inhaled steroids that will be permitted, for the duration of the trial

Adverse event data was collect over the life of the trial (12 weeks).

This study is limited by the absence of a vehicle-controlled arm and its small number of patients. The addition of patients on systemic medications may also confound the results of the study. The results would benefit from a larger cohort and longer study duration to assess for long term efficacy and adverse events.
