About this study
Official title: A Pilot, Single-center, Interventional Clinical Trial in Which Subjects With Polypoidal Choroidal Vasculopathy (PCV) Secondary to Age-Related Macular Degeneration (AMD) Will Receive Low Voltage Stereotactic Radiotherapy (IRay®) Treatment and Lucentis® Treatment as Needed.
This study will evaluate the efficacy of IRay treatment in patients with Polypoidal Choroidal Vasculopathy (PCV)secondary to AMD as determined by the change in the proportion of lesion activity and lesion size at 12 months.
Read the detailed description
This is a single-center, interventional clinical trial in which subjects will receive 16 Gy of IRay treatment and Lucentis, followed by Lucentis treatment as needed to evaluate the efficacy of IRay treatment in patients with PCV as determined by the change in the proportion of lesion activity and lesion size at 12 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IrayRadiation
The Oraya IRay stereotactic radiotherapy device will be used to deliver a 16 Gy dose of radiation to the macula. The radiotherapy will be delivered in a single session utilizing three sequential beams, each depositing 5.3 Gy at the macula through calculated scleral entry points, crossing the pars plana region of the eye, and overlapping at the same region of the macula.
| Study group | Role | What they receive |
|---|---|---|
| Iray plus Lucentis | Experimental | open label arm in which all subjects recieve a single 16 gy dose of radiation plus an injection of Lucentis. Receives: Radiation: Iray |
What is being measured
The primary outcome is the main question the study is designed to answer.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lesion change as measured with fluorescein angiography. (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
