A Study to Evaluate the Efficacy and Safety of Secukinumab in Adult Patients With Skin Types IV-VI With Moderate to Severe Plaque Psoriasis

ID#: NCT04571567

Age: 18 years - 66+

Gender: All

Healthy Subjects: Accepts Healthy Volunteers

Study Phase: Phase 4

Recruitment Status: Enrolling by invitation

Start Date: December 02, 2019

End Date: April 01, 2022


This will be a single-center, open-label clinical study to determine the efficacy and safety of secukinumab in the treatment of moderate to severe psoriasis vulgaris in skin of color (SOC) (FST IV-VI). This study will also evaluate the degree of erythema versus hyperpigmentation in psoriasis plaques in SOC (and its change with secukinumab treatment) as well as the effect of secukinumab on post-inflammatory hyperpigmentation and quality of life in SOC.


Inclusion Criteria:

- Provide written, signed and dated informed consent prior to initiating any study-related activities.

- Male or female ≥18 years of age at the time of screening

- Fitzpatrick Skin phototype IV-VI, non-white race/ethnicity, including but not limited to African Americans, Asians, Pacific Islanders and Hispanics

- Clinical diagnosis of chronic plaque-type psoriasis of the body for at least 6 months prior to randomization

- Moderate to severe plaque psoriasis at randomization as defined by: PASI≥12 AND BSA ≥ 10% AND IGA mod 2011 ≥ 3 (scale 0-4)

- Candidate for systemic therapy, as defined by having psoriasis inadequately controlled by topical treatments and/or phototherapy and/or previous systemic therapy

- Females of childbearing potential (FCBP) must have a negative pregnancy test at Screening and Baseline. While using investigational product and for at least 28 days after last application of investigational product, FCBP who engage in activity in which conception is possible must use one of the approved contraceptive options described below: Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner's vasectomy; OR Option 2: Male or female condom (latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]; PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.

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

Exclusion Criteria:

- Form of diagnosed psoriasis other than chronic plaque psoriasis (i.e. guttate, erythrodermic, pustular) or drug-induced psoriasis

- Subjects with lighter skin as defined by Fitzpatrick Skin Types I-III

- Subjects of European ancestry or other white ethnic group

- Previous exposure to secukinumab or other biologic agent targeting IL-17A or IL-17RA

- Ongoing use of prohibited treatments or lack of adherence to specified washout periods:

- 6 months for biologic drugs directly targeting IL-12/23 or IL-23, alefacept, and efalizumab

- 12 weeks for biologic agents other than the above (i.e. adalimumab, etanercept, infliximab)

- 4 weeks for other systemic psoriasis treatments (i.e. methotrexate, systemic steroids, retinoids, apremilast), and photochemotherapy

- 2 weeks for phototherapy (UVA, UVB)

- 2 weeks for topical psoriasis therapies

- Subjects unwilling to limit exposure to UV light

- Use of other investigational drugs within 5 half-lives prior to randomization

- Pregnant/nursing women or women of child-bearing potential unwilling to use appropriate method of contraception

- Diagnosis of other ongoing skin disease or skin infection that may interfere with the treatment and/or examination of psoriasis lesions

- Current significant medical problems or laboratory abnormalities that, in the opinion of the investigator, would put the patient at significant risk by participating in the study

- Previous history of or current infection with hepatitis C, hepatitis B, or HIV

- Active systemic infection during the 2 weeks prior to randomization

- Evidence of tuberculosis infection (indeterminate or positive quantiferon gold) at screening. Subject may be enrolled if full tuberculosis workup has been completed in the 12 weeks preceding randomization and patient has been started on appropriate treatment at least 4 weeks prior to randomization

- Malignancy with the past 5 years, with the exception of basal cell carcinoma, actinic keratosis, Bowen's disease of the skin, carcinoma in situ of the cervix(removed) or non-invasive malignant color polyps (removed)

- History of allergy to any component of the IP
