August 31, 2020 updated by: University of California, San Francisco

Characterization of the Response to Secukinumab in Plaque Psoriasis Using Novel Immunologic and Genetic Profiling

This is a single-arm, open-label study, which will examine the effect of secukinumab on the immunologic and genetic environment within psoriatic lesions.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Quantitative analysis of the immunologic changes in immune cell populations will be performed after secukinumab treatment in 15 patients at weeks 2, 4, and 12 compared to baseline week 0. The immunologic profiles in psoriasis patients will also be compared to healthy control skin surgical discard specimens (n=10). The number of differentially expressed genes in each cell population will be quantified by RNA-seq at weeks 2, 4, 12 after secukinumab compared to baseline.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Evidence of active tuberculosis infection as defined by a positive QuantiFERON TB-Gold test (QFT) with a positive chest X-ray at screening, or untreated latent tuberculosis defined by positive QFT with a negative chest X-ray without prophylactic therapy with isoniazid for a course of 9 months with one month of therapy completed prior to first dose of secukinumab.
  10. History of an ongoing, chronic or recurrent infectious disease including past medical history record of HIV, hepatitis B or hepatitis C.
  11. Subjects possess other diagnoses that, in the investigator's opinion, preclude him/her from safely participating in this study or interfere with the evaluation of the subject's psoriasis.
  12. History of known or suspected intolerance to any of the ingredients of the investigational study product.
