About This Trial

This is a multi-center, randomized, double-masked, active-comparator-controlled, Phase 3 study in a broad participant population (treatment-naïve and treatment-experienced) with neovascular (wet) age-related macular degeneration (nAMD). The study will evaluate a single intravitreal (IVT) injection of Ixo-vec compared to an active comparator. The primary endpoint of this study is the mean change in best corrected visual acuity (BCVA) of Ixo-vec compared to an active comparator measured at an average of Weeks 52 and 56. Safety, tolerability, and efficacy will be evaluated throughout the study.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Neovascular Age-Related Macular Degeneration (nAMD), Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 284 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Neovascular Age-Related Macular Degeneration (nAMD) subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Able and willing to provide willing to sign a consent form (or have a legally authorized representative who is able and willing to provide willing to sign a consent form) prior to any study assessments and procedures and comply with the study requirements and visits. 2. Male or female with a diagnosis of CNV secondary to nAMD in the study eye, with nAMD disease activity at Screening Visit 1. 3. At least 50 years old at Screening Visit 1. 4.

Who can participate in NCT06856577?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT06856577?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
