What is the purpose of this trial?

This trial aims to determine if adding tirzepatide, a medication for weight management, to ixekizumab benefits people with moderate-to-severe plaque psoriasis who also face obesity or are overweight with related health issues like high blood pressure or type 2 diabetes. The study will last up to 12 months, monitoring the effectiveness of this treatment combination. Participants should have been taking ixekizumab for about three months and have a body mass index (BMI) of 27 or higher. As a Phase 4 trial, this research seeks to understand how the already FDA-approved and proven effective treatment benefits a broader range of patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you must not have taken tirzepatide or similar medications before, and you should have been on ixekizumab for about 3 months before starting tirzepatide.

What is the safety track record for tirzepatide?

Research has shown that tirzepatide is generally safe for people. In a study involving adults with obesity but not diabetes, tirzepatide proved to be safe. The most common side effects were mild, such as nausea and diarrhea, and most people tolerated them well. Additionally, the FDA has already approved tirzepatide for treating type 2 diabetes, supporting its safety profile. People using it for diabetes have not reported any unexpected serious side effects. Overall, current evidence suggests that tirzepatide is safe to use, although individual experiences may vary. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Unlike the standard treatments for psoriasis and obesity, which often involve topical steroids, phototherapy, or oral medications, tirzepatide offers a unique approach. Tirzepatide is a peptide that acts as a dual agonist targeting both GIP and GLP-1 receptors, which are involved in regulating glucose and energy balance. This mechanism not only helps with weight reduction but also shows potential in modulating immune responses, which could benefit psoriasis patients. Researchers are excited about tirzepatide because it combines these two actions, potentially offering a more comprehensive treatment option for individuals dealing with both conditions simultaneously.

What evidence suggests that tirzepatide might be an effective treatment for psoriasis and obesity?

Research has shown that tirzepatide aids weight loss in individuals with obesity. One study demonstrated that participants who took tirzepatide weekly lost significant weight over 72 weeks. Another study found that even with slower dosage increases, participants still lost a substantial amount of weight within six months. Continuing tirzepatide helped maintain weight loss, while discontinuation led to weight regain. Although these studies focus on weight loss, this trial will examine how tirzepatide, when combined with ixekizumab, might also benefit psoriasis. Participants in this trial will continue receiving ixekizumab and take tirzepatide subcutaneously according to the label. ^{1 3 6 7 8}

Are You a Good Fit for This Trial?

This trial is for people with moderate-to-severe plaque psoriasis (PsO) who are also overweight or obese, and have at least one weight-related health issue. It's not clear what the specific exclusions are, but typically they would include certain medical conditions or treatments that could interfere with the study.

Inclusion Criteria

I started treatment with ixekizumab about 2-4 months ago.

I have been diagnosed with moderate-to-severe plaque psoriasis.

My BMI is over 27 and I have a weight-related health issue, or it's over 30.

Exclusion Criteria

Are currently enrolled in any other clinical study

Have a known hypersensitivity to tirzepatide or to any of its components

I have had pancreatitis before the first visit.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive ixekizumab and tirzepatide subcutaneously as per label

12 months

Follow-up

Participants are monitored for safety and effectiveness after treatment

4 weeks

What Are the Treatments Tested in This Trial?

Interventions

• Tirzepatide

Trial Overview

The trial is testing if adding a drug called Tirzepatide to another medication named Ixekizumab helps patients with PsO and obesity better than Ixekizumab alone. The study will observe participants for up to one year in a real-world clinical setting.

How Is the Trial Designed?

Group I: Tirzepatide Experimental Treatment 1 Intervention

Participants will continue to receive ixekizumab and take tirzepatide subcutaneously (SC) as per label.
