What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests vamikibart, a new treatment for uveitic macular edema, a condition where inflammation causes swelling at the back of the eye. The study aims to determine the safety and effectiveness of this treatment. Participants will be divided into three groups: one receiving a high dose, another a low dose, and a third receiving a sham (placebo) treatment. Individuals with macular edema from non-infectious uveitis who meet specific vision criteria may be suitable for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot have used certain eye treatments like IVT biologics, methotrexate, or specific implants within a few months before starting. It's best to discuss your current medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that vamikibart has been tested in people with uveitic macular edema, primarily to assess its safety. In one study, some participants experienced side effects such as eye problems and inflammation. However, the overall results indicated that vamikibart is generally safe for most people, as most did not encounter serious issues. While these findings are encouraging, individual experiences can vary. It is important to consult a healthcare provider about any concerns before joining a clinical trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Most treatments for uveitic macular edema, like corticosteroids or anti-VEGF injections, focus on reducing inflammation or inhibiting blood vessel growth. But vamikibart works differently, targeting the underlying cellular pathways involved in the disease with its unique mechanism of action. Researchers are excited because vamikibart, delivered via intravitreal injections, offers the potential for a more direct and potentially more effective approach by directly modulating these pathways. The treatment's ability to tailor dosing as needed after initial administrations could also mean more personalized and flexible care for patients.

What evidence suggests that this trial's treatments could be effective for uveitic macular edema?

Research has shown that vamikibart is a promising new treatment for uveitic macular edema (UME), a condition that causes swelling in the eye due to inflammation. This trial will evaluate different dosages of vamikibart, with participants receiving either high-dose or low-dose injections. Studies have found that vamikibart targets the inflammation causing UME, making it the first non-steroid option available. In earlier trials, patients experienced improvements in vision and eye health with few eye-related side effects. These results suggest that vamikibart could be an effective and safer alternative to current UME treatments. ^{1 3 4 5 6}

Trial Overview

The study tests the effectiveness and safety of Vamikibart in treating uveitic macular edema compared to a sham treatment (placebo). It aims to see how well Vamikibart works and monitors any side effects that occur during the trial.

How Is the Trial Designed?

Group I: Arm B Experimental Treatment 1 Intervention

Participants will receive 4 low-dose vamikibart IVT injections Q4W to Week 12, followed by PRN dosing from Week 20 to Week 48.

Group II: Arm A Experimental Treatment 1 Intervention

Participants will receive 4 high-dose vamikibart intravitreal (IVT) injections every 4 weeks (Q4W) to Week 12, followed by as-needed (PRN) dosing from Week 20 to Week 48.

Group III: Arm C Placebo Group 1 Intervention

Participants will receive 4 sham injections Q4W to Week 12, followed by PRN sham dosing from Week 20 to Week 48.
