Study of SFA002 in Patients with Mild to Moderate Psoriasis Plaques

Exclusion Criteria

• •The forms of psoriasis other than chronic plaque psoriasis (such as drug-induced psoriasis or guttate, erythrodermic, or pustular psoriasis) or if the psoriasis does not meet the criterion of chronicity (defined as a clinically significant flare of psoriasis within 12 weeks before baseline).
• •Presence of other form of inflammatory skin diseases (such as atopic dermatitis) or infectious diseases (such as cellulitis, warts, fungal cutaneous diseases, etc.)
• •A clinically significant flare of psoriasis within 12 weeks before baseline. (Note: The determination of whether prospective study participants had a "significant flare" prior to study baseline is left to the investigators. The intent of this criterion was to ensure the condition is sufficiently stable and aligned with the chronic nature of plaque psoriasis, so that an adequate assessment of the efficacy could be made.)
• •Prior or current use of psoriasis medications that might confound assessment of efficacy of the investigational supplements used in this study, unless there were used before their washout period prior to study initiation (see Table 2 for specific medications and their washout periods).
• •Known serious medical illness, such as significant cardiac disease (e.g., symptomatic congestive heart failure, unstable angina pectoris, symptomatic coronary artery disease, myocardial infarction within the past 6 months, uncontrolled or symptomatic cardiac arrhythmia, or New York Heart Association Class III or IV), or severe debilitating pulmonary disease, that would potentially increase subjects' risk for toxicity.
• •Known to have a history of risk factors for torsade de pointes (e.g., clinically significant heart failure, hypokalemia, family history of Long QT Syndrome).
• •Known to have arterial thrombotic event, stroke, or transient ischemia attack within the past 12 months.
• •Known to have uncontrolled hypertension (systolic blood pressure \>160 mm Hg or diastolic blood pressure \>90 mm Hg), or peripheral vascular disease ≥grade 2.
• •Known to have active central nervous system (CNS), epidural tumor or metastasis, or brain metastasis.
• •Any active uncontrolled bleeding, a bleeding diathesis (e.g., active peptic ulcer disease), or a history of bleeding (e.g., hemoptysis, upper or lower gastrointestinal \[GI\] bleeding) within the past 6 months.
• •Dyspnea with minimal to moderate exertion; large and recurrent pleural or peritoneal effusions requiring frequent drainage (e.g. weekly); or any amount of clinically significant pericardial effusion.
• •Diabetes of any type, except Non-Insulin Dependent Diabetes Mellitus (NIDDM) that is controlled and with hemoglobin A1c 8%.
• •Evidence of active infection during screening, or serious infection within the past month.
• •Patients with known Human Immunodeficiency Virus (HIV), hepatitis B or C virus (HBV) or (HCV), respectively), or active or latent Tuberculosis (TB).
• •Serious or non-healing wound, skin ulcer, or bone fracture.
• •Abdominal fistula, GI perforation, or intra-abdominal abscess within the past 6 months.
• •Neuropathy of grade ≥2.
• •Pregnant or lactating females.
• •Patients like to purposely undergoing sunlight exposure, including the skin area where the plaques being investigated are located, during the study
