Impact of Glucagon-like Peptide-1 (GLP-1) Analogs on Disease Outcomes in Psoriatic Arthritis: A Pragmatic Randomized Controlled Trial
What this study is about
Psoriatic arthritis (PsA) is a chronic inflammatory condition that affects the joints but can also have an effect on multiple parts of the body.
View original scientific description
Psoriatic arthritis (PsA) is a chronic inflammatory condition that affects the joints but can also have an effect on multiple parts of the body. This study will assess if the effectiveness of Glucagon-like peptide-1 (GLP-1) medications used to treat type 2-diabetes and weight management, or nutrition counseling can better treat individuals with Psoriatic Arthritis who are also needing treatment for obesity and type 2 diabetes. The main objectives it aims to answer are: To assess disease outcomes of PsA patients undergoing treatment for concomitant obesity and type 2 diabetes with GLP-1 analogs vs nutrition counseling. To assess effectiveness as measured by clinical and patient reported outcome measures in patients treated with GLP-1 and nutrition counseling. Participants will be randomized to receive a GLP-1 or nutrition counseling. Participants will be asked to come to the study center at most four times during a 24-week period. During this time participants will be asked to fill out questionnaires, receive a physical exam, and have their blood drawn.

Primary outcome measures
Change from the baseline Minimal Disease Activity (MDA) Scores at Week 12 and 24 with GLP-1 Agonists vs Nutrition Counseling
Time frame: Week 12 and 24
In order to meet Minimal Disease Activity (MDA) participants need to meet 5 of the 7 criteria: tender joint count less than or equal to 68 and greater than or equal to 1 (TJC68), swollen joint count less than or equal to 66 and greater than or equal to 1 (SJC66), psoriasis body surface area is less than or equal to 3%, patient pain Visual Analogue Scale (VAS) is less than or equal to 15mm, patient global disease activity VAS is less than or equal to 20mm, Health Assessment Questionnaire (HAQ) is less than or equal to 0.5 and tender entheseal points is less than or equal to 1. One of the outcomes of this study is to see how these scores change with the participants receiving a GLP-1 or nutrition counseling.
Proportion of Patients who Achieve Disease Activity in Psoriatic Arthritis (DAPSA) Remission with GLP-1 Agonists Vs. Nutrition Counseling at Week 12 and 24
Time frame: Week 12 and 24
DASPA is a composite measure based on the summation of four variables: tender and swollen joints (TJC68, SJC66), C-reactive protein (CRP), Patient Global Assessment (PtGA) and Patient Pain both reported on a 0-100 mm VAS. DASPA classifications validated for PsA include Less than or equal to 4 (remission), greater than 4 but less than or equal to 14 is low disease activity. Greater than 14 but less than or equal to 28 is moderate disease activity and greater than 28 is high disease activity.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
