Modifying PEST for Psoriatic Arthritis Screening (ScreenX)

June 2, 2026 updated by: Novartis Pharmaceuticals

A Multicenter, Prospective, Study to Evaluate the Impact of Modifying the Validated Psoriasis Epidemiology Screening Tool (PEST) on the Potential Diagnosis of Psoriatic Arthritis in Adult Patients With Moderate-to-severe Plaque Psoriasis in Canada ("ScreenX")

The purpose of this study is to assess the impact of adding two questions and pictures to the validated PEST on the potential diagnosis of PsA in participants with moderate-to-severe plaque PsO in Canada.

Recruiting

Detailed Description

Patients will be enrolled in the study for up to 120 days and will be asked to fill-out a PsA screening questionnaire at their first dermatologist visit. Patients screening positive for PsA will have a second visit with a rheumatologist where a full PsA diagnosis assessment will be performed. A remote 'end of study' (EOS) visit will be conducted by the dermatologist to document the patient's biologic Disease-Modifying Antirheumatic Drugs (bDMARDs) treatment choice and status.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: PEST Screening group

When visiting their dermatologists, all eligible patients with moderate-to-severe plaque psoriasis (PsO) eligible for treatment with biologic Disease-Modifying Antirheumatic Drugs (bDMARDs) will be screened for psoriatic arthritis (PsA) using PEST+pictures+2, a variation of the PEST screening tool.

The PEST+pictures+2 is made up of 3 components:

  1. Psoriasis Epidemiology Screening Tool (PEST) consisting of 5 simple questions
  2. PEST+2 refers to the PEST modified with two additional questions (Do you have morning stiffness that lasts for more than one (1) hour? Do you wake up at night because of low back or buttock pain?), AND
  3. PEST+pictures which provides an opportunity for patients to modify their answers to PEST questions 1, 3, and 5 by presenting them with pictures of swollen joints, fingernail pitting, and swollen fingers and toes.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Positive Predictive Value (PPV) for PEST and PEST+2 in adult patients with moderate-to-severe plaque PsO who are candidates for bDMARDs
Time Frame: Up to approximately 1 year
To assess the impact of adding two questions (morning stiffness and low back or buttock pain) to the validated PEST for the potential diagnosis of PsA in moderate-to-severe plaque PsO patients who are candidates for biologic disease-modifying antirheumatic drugs (bDMARDs) The primary clinical question of interest is: Can the addition of two questions to PEST pertaining to presence of morning stiffness and low back or buttock pain (i.e., PEST+2) allow for improved screening and diagnosis of PsA in patients with moderate-to-severe plaque PsO?
Up to approximately 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
