Safety and Efficacy of Secukinumab in Mild Psoriasis

Clinical Trial ID: NCT03131570


Mild psoriasis not only progresses to moderate-to-severe psoriasis but also precedes systemic inflammation that leads to psoriatic arthritis and cardiovascular comorbidities. By curing mild psoriasis with a short-term anti- interleukin (IL)-17A treatment, investigators may reduce the costs of treating psoriasis and associated medical conditions, including psoriatic arthritis, cardiovascular disease, and diabetes.

Psoriasis is an immune-mediated disease of the skin that, even in mild disease, increases the risk of comorbidities such as cardiovascular disease and metabolic derangements. Mild psoriasis tends to be treated with topical drugs, while moderate-to-severe disease is optimally treated with systemic immune modulators. However, the treatment of "mild" psoriasis needs to be re-thought because recent studies have revealed that mild psoriasis is characterized by stronger expression of pathogenic molecules, such as interleukin (IL)-17A, and higher numbers of T cells in the skin, compared to severe psoriasis. A key distinction between mild and severe psoriasis is now discovered to be the higher expression of negative immune regulatory genes in mild lesions. Therefore, targeted immune therapy with anti-IL-17A, which is highly effective in severe psoriasis, might be equally (or even more) effective in mild disease. Also, restoration of immune tolerance might be more easily achieved in mild disease. Thus, short-term anti-IL-17A treatment of mild psoriasis might prevent the recurrence and eventually cure the disease. The aim of study is to test this hypothesis by exploring whether 3 months or 6 months of anti-IL17A treatment will prevent relapses after medication has been discontinued in mild psoriasis patients.


Inclusion Criteria: 1. Written informed consent must be obtained before any assessment is performed 2. 18 years of age or older 3. Chronic plaque-type psoriasis for at least 6 months 4. Negative PPD (negative chest w-ray if positive) or negative QuantiFERON-TB Gold 5. Have a PASI between 6 and 12 and Body Surface Area (BSA) affected by plaque-type psoriasis less than 10% at screening and baseline 6. Willing to wash off steroid creams and ultraviolet B light (UVB) therapy for 2 weeks prior to the baseline visit Exclusion Criteria: 1. Has a nonplaque form of psoriasis (eg, erythrodermic, guttate, or pustular) 2. Has previously received Secukinumab or other biologics 3. History of Inflammatory Bowel Disease (IBD) 4. History of Rheumatoid Arthritis 5. Use of topical treatments for psoriasis, including steroids, vitamin D derivatives, vitamin A derivatives, salicylic acid, tar (except moisturizers) and/or ultraviolet A light (UVA)/UVB phototherapy within the last 2 weeks (if these have used them, the participant needs to wash off of them for at least 2 weeks after signing consent prior to baseline) 6. Is pregnant, nursing, or planning a pregnancy (both men and women) within 5 months following the last administration of study drug 7. Has recently received or is planning to receive a vaccination while on the study 8. HIV positive 9. Chronic untreated hepatitis C, positive hepatitis B surface antigen and acute hepatitis A infection 10. Known tuberculosis (TB) or evidence of TB infection. Subjects with a positive QuantiFERON; TB test or a positive purified protein derivate (PPD) skin test result may participate in the study if further work up (according to local practice/guidelines) establishes conclusively that the subject has no evidence of active TB. 11. Any severe, progressive or uncontrolled medical condition at screening that in the judgment of the investigator prevents the subject from participating in the study.
