This is a phase IV, single-center, open label, single arm study in which a group of 30 subjects with moderate to severe plaque psoriasis will receive secukinumab therapy. Non-invasive imaging with optical coherence tomography (OCT) will be used to monitor the resolution of psoriatic plaques with treatment in comparison to observed clinical improvements. Early subclinical finding will be used to elucidate drug mechanism of action. Assessment will be based on intrasubject comparisons, and all findings will be compared to patients baseline imaging.


Secukinumab, an anti-IL-17A monoclonal antibody, is an effective treatment for moderate to severe plaque psoriasis.While there is an abundance of clinical data in the literature supporting the clinical efficacy of this therapy, there is limited data on early disease clearance and other histologic findings elucidating a drug mechanism of action. Hyper-proliferation of the epidermis and inflammation of dermis seen in psoriasis are thought to be due to persistent T-cell activation and production of several pro-inflammatory cytokines by dermal immune reaction. Therefore, with treatments with immunomodulatory effects, such as Secukinumab, monitoring markers of inflammation, angiogenesis, and collagen synthesis would be useful in establishing mechanism of action. While a skin biopsy can show these findings at one moment in time, it does not allow for repetitive monitoring overtime. The investigators propose the use of non-invasive imaging with Optical Coherence Tomography (OCT) to demonstrate histologic features of plaque psoriasis not clinically evident. Upon completion of the study, the investigators will assess when OCT improvements of psoriasis treatment are detectable and how these findings correlate to observed clinical improvements.

Inclusion Criteria

Male or female subject at least 18 years of age with a diagnosis of moderate to severe chronic plaque psoriasis vulgaris for at least 6 months
Subjects must be candidates for systemic therapy and have at least moderate to severe psoriasis, as defined by the Psoriasis Area and Severity Index (PASI) score: body surface area (BSA) involvement >10% , PASI >12 and/or IGA modified (mod 2011) score of 3 ("moderate") or 4 ("severe"). [2-4]
Patients must be nave to prior biologic treatment
Subject is able to provide written informed consent and comply with the requirements of this study protocol
Subjects who are women of childbearing potential must have a negative urine pregnancy test at screening and must be practicing an adequate, medically acceptable method of birth control for at least 30 days before Day 0 and at least 6 months after the last study drug administration. Acceptable methods of birth control include intrauterine device (IUD); oral, transdermal, implanted or injected hormonal contraceptives (must have been initiated at least 1 month before entering the study); tubal ligation; abstinence and barrier methods with spermicide. Otherwise, if not of childbearing potential, subjects must: have a sterile or vasectomized partner; have had a hysterectomy, a bilateral oophorectomy or be clinically diagnosed infertile; or be in a menopausal state for at least a year
Tuberculin purified protein derivative (PPD) or QuantiFERON TB-Gold test (QFT) negative at the time of screening, or if patient has a history of positive PPD or QuantiFERON, he/she has completed the appropriate prophylaxis
Subject is judged to be in good general health as determined by the principal investigator based upon the results of medical history, laboratory profile, and physical examination

Exclusion Criteria

Patients with guttate, erythrodermic, exfoliative, or pustular psoriasis, other skin conditions affecting the treatment area, severe hepatic disorders or severe renal insufficiency
Have received systemic psoriasis treatments (such as psoralen and PUVA light therapy, cyclosporine, corticosteroids, methotrexate, retinoids, mycophenolate, hydroxyurea, azathioprine, sirolimus) or phototherapy within the previous 4 weeks; or have had topical therapy within the previous 2 weeks
Have received any biologic agent for the treatment of psoriasis, including etanercept, infliximab or adalimumab, alefacept, ustekinumab, or any other biologic agent
Use of other drugs with potential effect on psoriasis, such as beta blockers, antimalarials, angiotensin-converting enzyme inhibitors, and lithium, are allowed, provided that treatment was not initiated and the dosage did not change during the trial
Any subject who is pregnant or refuses to practice an acceptable method of birth control (as stated in inclusion criterion # 4)
History of an ongoing, chronic or recurrent infectious disease, or evidence of tuberculosis infection as defined by a positive tuberculin purified protein derivative (PPD) or QuantiFERON TB-Gold test (QFT) at screening. Subjects with a positive or indeterminate PPD or QFT test may participate in the study if a full tuberculosis work up (according to local practice/guidelines) is completed within 12 weeks prior to randomization and establishes conclusively that the subject has no evidence of active tuberculosis. If presence of latent tuberculosis is established, then treatment must have been initiated at least for 4 weeks prior to randomization and the course of prophylaxis is planned to be completed
Active Crohn's disease
History of significant allergies or intolerances
Imumunocompromised patients, including Subjects with a history of TB, HIV, Hepatitis B or Hepatitis C infections
Have had live vaccination within 12 weeks prior to study
Have evidence of active infection, such as fever, within 5 days of dosing
